Hyundai Tucson Fuel Cell 2017 — Problemas reportados

While driving down the highway, the check engine light started to flash. Once the car was turned off and back on again, it shook violently. It was hard to keep it in the lane and I was worried it would cause an accident. It was driven off the highway while constantly shaking. Once it sat off for roughly 30 minutes, it would turn on, but wouldn't turn over and drive. It was towed to a dealership where it was diagnosed, though I was never given anything past a verbal "it stopped compressing". It turns on and over, but makes a grinding noise. It will die and turn off the engine after roughly 45 minutes. This had never happened before. *I've been told a few different things by people who hear about the problem, but I've never received a real diagnosis by the Hyundai dealership it is located at. It has always had a oil consumption problem, adding roughly one quart of oil every 800-1000 miles. It has had oil changes every 5,000 miles. It also had a hard time when cold-started accelerating, but would work fine once heated up. It is available for inspection upon request.

The issues is the engine shuts off at idle or in motion. Sometimes hard to start but it cranks over well. Then when it restarts after a shut down, three lights stay on some traction control, the steering and a picture of a car downhill with a clock or engine RPM light. No check engine light on. Then recently the tachometer doesn’t work after a shutdown then restart. But when you turn off the engine with ignition, then restart the third time. The lights all go off then the RPM gauge works. But the whole time the engine runs great. When I check ECM all is good no Fault codes, I monitor fuel pressure the low psi is 40 the high side is 999 psi. Is this a common issue with these cars?

My name is [XXX]. My husband, [XXX], and I purchased a 2017 Hyundai Tucson (VIN: [XXX]) from a Hyundai dealership in 2023 with 53,920 miles for our daughter to commute to school. The vehicle now has approximately 77,940 miles, and she is still attending school. Since purchasing the vehicle, we have consistently returned to the same Hyundai dealership for regular maintenance, trusting its professionals to keep the vehicle safe and reliable. While driving on the freeway, our daughter suddenly lost engine power. The vehicle slowed down and would no longer accelerate. Thankfully, she managed to exit the highway before it stopped completely. Highway patrol assisted her in moving the vehicle to the roadside. The Check Engine Light and oil-pressure warning light came on, the engine made a pronounced knocking sound, and it would no longer run. We believe these symptoms closely resemble the engine defect described in Hyundai's Recall 209 (NHTSA 21V-727), involving connecting-rod-bearing failure in certain 2017 Tucson vehicles. Hyundai Motor America denied our request for assistance, stating that our VIN is not included in the recall and that no warranty coverage applies. We respectfully question whether vehicles experiencing the same or substantially similar defect may have been excluded from the recall. We request a technical investigation into why our vehicle was excluded and whether its engine failure is related to the recalled defect. This was a serious safety concern, not merely a repair expense. Our daughter could have suffered a serious accident had she been unable to exit the freeway safely. We are grateful she escaped without injury. We respectfully request that Hyundai reconsider its decision, review the vehicle's maintenance and diagnostic records, and investigate the engine failure. If the failure is related to the recalled defect, we ask Hyundai to cover the cost of engine repair or replacement.

The contact owns a 2017 Hyundai Tucson. The contact stated that while stopped at a stop light, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that the accelerator pedal was depressed to the floorboard, and the vehicle jumped forward and then stopped. The contact stated that the vehicle was stuck in the middle of a busy highway. The vehicle was coasted to the shoulder of the roadway. The vehicle was taken to the dealer, where it was diagnosed with a dual clutch failure. The contact was informed that the dual clutch needed to be replaced. The contact stated that the failure was a known failure with the vehicle. The manufacturer was made aware of the failure, and a case was filed. The contact was informed that the repair was not covered under a special coverage program. The failure mileage was approximately 133,000.

On [XXX], I purchased a 2017 Hyundai Tucson from DriveTime, located at 6400 Pensacola Boulevard, Pensacola, FL 32505. Within approximately nine days of purchase, the vehicle began experiencing serious mechanical problems, raising significant concerns about its safety and roadworthiness. On [XXX], the vehicle suffered a severe loss of acceleration and was unable to exceed approximately 30 mph. This sudden reduction in engine performance created a dangerous situation while driving, particularly when attempting to maintain normal traffic speeds. Following these issues, mechanical inspections revealed water inside the spark plug wells, a severely rusted ignition coil, and a failing catalytic converter. Firestone estimated the catalytic converter repair at approximately $5,000. The presence of water and corrosion raised concerns about possible pre-existing damage and whether the vehicle had been properly inspected before being sold. The vehicle remained in repair-related custody for approximately 29 days. Despite repeated communications with DriveTime, the mechanical problems were not satisfactorily resolved. DriveTime representatives informed me that a replacement vehicle had been approved. On [XXX], I returned to the dealership expecting a replacement but was informed that no suitable vehicle was available. I was left without transportation, and the dealership failed to provide a satisfactory resolution. As of October 21, 2026, I remain without a vehicle. I am requesting that NHTSA investigate the sudden loss of engine power, possible electrical or ignition system damage caused by moisture intrusion, and any similar safety complaints involving the 2017 Hyundai Tucson. My primary concern is that these mechanical failures could cause another driver to experience a dangerous loss of power while operating the vehicle, potentially resulting in a serious collision.

engine failure even though this car has always had oil changes at 110,000 miles. I would like the company to fix this since i am not the first to complain about this. I still have the car parked.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at 65 MPH, the vehicle unexpectedly stalled and was unable to exceed 30 MPH. The contact pulled the vehicle over to the shoulder of the road, and the vehicle failed to restart. The vehicle was towed to the dealer, where it was diagnosed that the transmission failed and oil contaminated the catalytic converter, causing the catalytic converter to fail and require replacement. The transmission was repaired by the dealer, and the catalytic converter was replaced by an independent repair facility. The contact subsequently observed continued oil loss following the repairs. The vehicle was returned to the dealer, where it was diagnosed that the exhaust manifold headers failed and required replacement. The vehicle was not repaired. The contact requested and received a complete diagnostic report from the dealer. The failure mileage was approximately 90,502.

While going down the highway at around 72 mph , my car went into limp mode. I was unable to accelerate, the brake and wheel locked. And then the engine light began flashing. The limp mode , non acceleration, and flashing engine light have happened twice before this instance. The first two times the pulled the P1326 knock sensor code and replaced it. Did the update, and sent me on my way saying it was fine. Now this most recent time (the 3rd time), the engine has failed. A CARFAX report says my car already had the engine replaced at 52k miles, meaning there’s 1 something internally wrong and 2 it’s still well within mileage warranty for another engine replacement. This car is extremely dangerous as it can literally stop in the middle of the highway. I went from 72 to about 15 mph in seconds, I was unable to get over or accelerate. It was terrifying. Now dealing with Hyundai - they don’t want to take fault.

Unknown believe it engine was replaced due to engine knock

Failed Component: Engine assembly / internal powertrain (specifically, a connecting rod bearing failure in cylinder #2 causing severe engine knocking and risk of mechanical seizure). The vehicle is available for inspection, the complete vehicle and affected engine assembly are intact and available for inspection upon request at CMA's Hyundai of Lexington Park: [XXX] Safety Risk: A rod bearing failure causes violent engine knocking, severe loss of engine power, and eventual engine seizure or stalling while driving. Losing propulsion unexpectedly—especially at highway speeds or in heavy traffic—creates an immediate collision risk for the vehicle occupants and surrounding traffic due to sudden loss of power, power steering, and power brake assistance. The issue was formally diagnosed and confirmed by an authorized Hyundai dealership service department. The technician performed a physical diagnostic evaluation and officially documented a knocking condition resulting from a connecting rod bearing failure in cylinder #2. Symptoms & Timeline: Initial engine knocking noises first appeared on XXX. The vehicle was previously updated with Hyundai's Knock Sensor Detection System (KSDS) Product Improvement Campaign, which is intended to detect excessive vibration from rod bearing wear prior to catastrophic failure. No check engine light illumination occurred or and type of indication from the vehicle there was something wrong other than the knocking noises.

I am reporting a suspected safety defect involving my daughter's 2017 Hyundai Tucson, VIN [XXX], with approximately 77,940 miles. The vehicle experienced an engine failure beginning with the illumination of the oil-pressure warning light and Check Engine Light, followed by a pronounced engine knocking noise. The vehicle subsequently could not continue running. The vehicle was inspected by a Hyundai dealership, which diagnosed an engine failure. I am aware of Hyundai Safety Recall 209 / NHTSA Recall 21V-727 involving certain 2017 Hyundai Tucson vehicles equipped with the 2.0-liter Nu GDI engine. Hyundai's recall documentation identifies premature connecting-rod-bearing wear and specifically identifies abnormal engine knocking and illumination of the oil-pressure warning light as symptoms that can precede engine damage and stalling. My daughter's vehicle experienced these same symptoms. Hyundai has informed us that this particular VIN is not included in Recall 209 and Hyundai Motor America has denied our request for assistance. I am therefore asking NHTSA to review this complaint as a potential safety defect and determine whether there may be additional 2017 Tucson vehicles outside the current Recall 209 population experiencing the same or substantially similar engine failure. I am not claiming that the vehicle is definitively covered by Recall 209. Rather, I am asking NHTSA to investigate whether the exclusion of this vehicle is appropriate given the similarity between the actual failure symptoms and the defect identified in Recall 209. I can provide the dealership's diagnostic documentation, Hyundai Motor America's denial, photographs, maintenance records, and other supporting information upon request.

The contact owns a 2017 Hyundai Tucson. The vehicle was taken to the dealer for an engine replacement due to a separate issue; however, during the service, the dealer discovered that the front axle was leaking and noted that the steering was becoming stiff. The contact had not experienced any issues prior to the vehicle being taken to the dealer. The contact stated that the dealer had damaged the vehicle during the engine replacement. The manufacturer was notified of the failure and stated that the dealer would be contacted about a courtesy repair for the axle. The dealer confirmed the failure.

Vehicle is losing a lot of oil. But there is no oil leaking on the ground. Upon looking at the safety recall, it says it might be fire hazardous. I noticed smoke coming from under the hood. Vehicle run rough and also hear sounds.

Franchise dealer Preson Hyundai is actively obstructing a court-ordered settlement tracking test for an engine burning 2.0 qts internally, forcing a young driver with child to operate an oil starving vehicle at risk of highway engine seizure and fire.

I have a 2017 Hyundai Tucson with a 1.6 turbo engine, and I have been experiencing massive oil consumption. Oil is coming out of the tail pipe with occasional big puff of smoke out of the tailpipe. Skipping and hesitation during acceleration, rough cold start, I have previously had the check engine light on with a multiple misfire code. I changed the plugs and the coils, and it did not resolve the problems. I then took it to the mechanic, and he told me that the car has to go to Hyundai because these are known problems with my particular motor. I took it to Balise Hyundai in Hyannis Mass. and was told that they know about these motor issues but could not help me because the engine light was not on.' If the light comes on, then bring it back and we will check it out'.I was then told that any work performed would be my responsibility to pay for it out of my pocket. If it a known problem by Hyundai, then I think that a recall or something should be posted so customers are not stuck with a very big service bill. Any help to get my vehicle running the way it was designed to would be greatly appreciated. Apparently, there are no recalls or campaigns about these issues on my vehicle even though they are well known to Hyundai

My transmission warning light is currently on. I’ve had problems with the transmission and the dual clutch. My car falls on the cusp of 2016-2017 dual clutch problems. The 2016 was recalled although 2017 has not. Hyundai has received numerous complaints just like this and nothing has been resolved.

I keep having to add oil but there is no puddle from a leak on the ground. There is also no smoke coming out of the exhaust. It is using an excessive amount of oil.

Car was driving weird Consuming lots of oil Check engine light flashing Took to mechanic where they replaced the spark plugs and ignition coils, cleared light. Issue was resolved for about a month. Rough idling began car begin to shake while driving. Took back to shop was told rod bearring problem. Upon research found out this is a COMMKON problem among Hyundai vehicles however my vehicle was not apart of the ‘affected batch’. Took to Hyundai and got a diagnostic where it was confirmed that a new engine was needed, for $9000.

The Core Symptoms: "The high-pressure fuel pump is leaking internally. Raw gasoline is flooding into the engine oil crankcase, causing severe fuel dilution. The engine air filter is physically soaked in raw fuel and smells strongly of gasoline." My engine is always extremely hot after I have only went 15 mins away from home. Sometimes takes over two hours to cool down. The Safety Risk: "When attempting to accelerate, the vehicle experiences severe fuel starvation, causing the engine to bog down and act like it is going to stall in the middle of traffic, creating a severe crash hazard. Additionally, there is a loud 'popping' sound/mini-backfire upon turning the vehicle off due to unburnt fuel vapors, presenting a high risk of an underhood engine fire. I have only 83,000 miles on my car.

Subject: Formal Safety Complaint Regarding Steering Failure – 2017 Hyundai Tucson To Whom It May Concern, I am submitting this complaint to request that the National Highway Traffic Safety Administration (NHTSA) investigate a potentially serious safety defect involving the Motor-Driven Power Steering (MDPS) system in my 2017 Hyundai Tucson. I am the second owner of this vehicle. The vehicle currently has approximately 61,000 miles and remains within Hyundai's 10-Year/100,000-Mile Powertrain Warranty period applicable to subsequent owners. Approximately two years ago, the vehicle's engine was replaced under a Hyundai safety recall. Recently, I began experiencing intermittent steering problems in which the steering wheel becomes extremely difficult to turn and appears to momentarily jam or lock while driving. This condition significantly affects vehicle control and creates a serious safety hazard, particularly during turns, lane changes, or emergency maneuvers. I brought the vehicle to Advantage Hyundai in [XXX] for diagnosis. The dealership determined that the vehicle had a Motor Position Sensor Error (Diagnostic Trouble Code C2401) within the Motor-Driven Power Steering (MDPS) system. The dealership informed me that the repair is not covered under the vehicle's warranty and declined to repair it. The dealer also submitted a request to Hyundai for goodwill assistance (Prior Authorization No. XXX), but Hyundai denied that request. I subsequently contacted Hyundai National Consumer Affairs (Case No. XXX) seeking assistance. Unfortunately, Hyundai also denied my request despite the relatively low mileage and the serious safety implications of the steering malfunction. My concern extends beyond the cost of repair. A malfunction in the electronic power steering system that causes steering to bind, jam, or become difficult to control presents a significant risk of a crash, injury, or loss of life.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, an abnormal knocking sound was heard coming from under the hood, and the RPMs independently increased. The "Check Engine Oil" warning light illuminated. The contact managed to pull over to the shoulder of the road, and the vehicle was towed to a local Midas shop, where it was diagnosed with total engine failure.The vehicle was towed to a local dealer, who discovered metal shavings in the engine oil pan during diagnosis. The vehicle was not repaired due to the high cost. Upon further investigation, the contact associated the failure with an unknown NHTSA Campaign number. The manufacturer was made aware of the failure. The failure mileage was approximately 62,000.

#1. This vehicle uses a lot of oil !!! It burns through it like crazy I have to check the oil every other day. #2. When I come to a stop while driving and give it gas to take off IT WONT GO !!!!! It hesitates and when it does go it LUNGES FORWARD!! This is a huge manufacturer problem not a buyer problem. The engine is junk.! 3. I’ve called numerous places to get help. This car needs to be recalled. This is a huge safety violation. It doesn’t wanna go when you give it gas and when it does, it lunges forward that can cause a huge accident on the highways. This car was made in China. It is junk. I’ve called to get help with this issue and no one wants to help. Nobody returns my calls and I’ll Hyundai wants to do is it even more money out of me when this isn’t my fault the car is junk. For safety concerns I would like someone to call me at [XXX].

I am filing a safety complaint regarding my Hyundai vehicle after experiencing a sudden engine failure that appears consistent with known rod bearing and engine defects affecting certain Hyundai engines. While driving, my vehicle began making a knocking noise and shortly thereafter suffered catastrophic engine failure. The engine lost power and became inoperable, requiring the vehicle to be towed. This failure occurred without any prior indication that the engine was about to fail. My concern is that this type of engine failure creates a significant safety hazard because it can occur unexpectedly while driving, potentially causing a loss of power in traffic and increasing the risk of a crash. The dealership inspected the vehicle and engine but did not report excessive sludge buildup. I have provided available maintenance records showing that oil changes were performed during my ownership. Despite this, there appears to be disagreement regarding the cause of the failure. I am aware of reports involving rod bearing and engine failures in similar Hyundai vehicles and believe NHTSA should investigate whether this failure is related to a broader manufacturing or design defect. The cost of replacing the engine is substantial, and consumers may be placed at risk if these failures occur while vehicles are being operated on public roads. I am requesting that NHTSA review this issue and determine whether additional investigation, recalls, or other corrective actions are warranted.

While traveling on the highway the car began to lose speed rapidly until coming to a complete stop, no warning lights were present prior.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at undisclosed speeds, the vehicle was consuming an excessive amount of engine oil. The contact stated that oil was frequently added to the engine. The vehicle became inoperable. The vehicle was towed to a dealer, where it was diagnosed and determined that the catalytic converter needed to be replaced. The catalytic converter was replaced; however, the failure persisted. The vehicle was returned to the dealer for inspection, and the catalytic converter was replaced a second time. The vehicle was repaired; however, the failure persisted. No additional repairs were performed. The manufacturer was notified of the failure. The approximate failure mileage was 86,000.

Catastrophic engine failures AT 57k miles while driving, resulted in engine replacment under recall warranty. Timing chain replacement done at 93K miles. Second Engine failure while driving at 107K. Hyundai refuses to fix the engine.

The engine (connecting rod bearings in the 2.0L Nu GDI engine) failed. The vehicle entered limp mode with DTC P1326, then died on the road and the engine seized completely (will not turn by hand when attempted; only clicks on starter). It is currently at First Hyundai dealer in [XXX], under Repair Order #XXXand available for inspection. The vehicle suddenly lost power and died while driving on the road. This created a significant risk of an accident or being stranded in traffic. I was on a busy highway and almost got hit twice. There is also a known fire risk associated with this exact defect (oil leaking onto hot engine components), as stated in Recall 209 (NHTSA 21V727). The vehicle was towed to First Hyundai. They have documented the no-start/seized condition on Repair Order #XXX. A prior independent scanner reading showed P1326 before the code was cleared. The dealer has not performed the full diagnostic inspection (scheduled around June 11). Hyundai Corporate (Claim #XXX) has been notified but has not responded after multiple escalation emails. The vehicle first went into limp mode ("Engine Protection Mode") with DTC P1326 on the scanner. Shortly after, the engine died completely and would not restart. This occurred after Recall 209 (bearing/KSDS campaign) was completed on XXX. Additional Details: This is a known issue with premature connecting rod bearing wear. The dealer is refusing to provide a loaner/rental upon drop-off, which contradicts TSB 22-01-023H (Dealer Best Practices for P1326 vehicles). The vehicle has been inoperable since 6/4 ..with no resolution. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2017 Hyundai Tucson | VIN: [XXX] | Mileage: 75,000 I have owned this vehicle for approximately five years and have experienced severe excessive oil consumption for the past two to three years. The issue was first discovered when the vehicle entered protective mode due to critically low oil levels despite a routine oil change having been performed only a few months prior. I am currently required to add approximately one quart of oil every month to maintain safe operating levels. I visited an authorized Hyundai dealership to have an oil consumption test performed. The dealership informed me that if the test confirmed excessive consumption, I would be required to pay out of pocket for an engine replacement. I declined, as Hyundai Motor America has publicly acknowledged this exact defect in the 2017 Tucson through NHTSA Recall 21V727000, multiple Technical Service Bulletins, and a class action settlement covering 2014-2021 Tucson vehicles with the Nu 2.0-liter GDI engine. My VIN was found ineligible on the class action settlement website despite the acknowledged defect. Hyundai has admitted this engine suffers from premature bearing wear, excessive oil consumption, and risk of engine failure and fire. I am requesting NHTSA investigate why my VIN falls outside current recall coverage despite presenting identical symptoms to affected vehicles.

Left rear passenger door latch failure to open either from inside or outside. This is a mechanical failure of the cables operating the latch. A passenger could not easily exit the vehicle in an emergency situation, also there is no way short of breaking the glass to easily access or if necessary extricate the passenger in an emergency situation. As evidenced from online searches and forums this failure is all too common and has been addressed with a narrow set of vehicles with an extended warranty applied to this failure. This is an issue of safety. There needs to be a recall to upgrade affected vehicles and their door mechanisms.

I am submitting a complaint regarding a 2017 Hyundai Tucson Ultimate AWD equipped with the 1.6L Turbo Gamma GDI engine. My vehicle currently has approximately 127,000 miles and has experienced sudden engine knocking consistent with rod bearing failure and/or catastrophic internal engine damage. The vehicle has been properly maintained, including regular oil changes. However, the engine began consuming excessive oil without warning. Upon inspection by an independent repair facility, the engine was found to have extremely low oil levels despite being within the normal oil change interval. After refilling the oil, the engine continued making severe knocking noises, and the repair facility advised that the engine is likely non-repairable and requires replacement. This failure appears materially similar to the rod bearing and engine failure issues already widely documented in Hyundai/Kia engine defect investigations and class action settlements involving related Gamma and GDI engine platforms. I have learned that Hyundai extended warranties for certain vehicles with similar engine defects up to 15 years/150,000 miles; however, my specific Tucson trim/engine configuration does not appear included despite experiencing the same type of failure. This vehicle has also previously required major drivetrain repairs under warranty, including two transmission replacements and turbocharger replacement. My concern is both financial and safety-related. A sudden engine failure or seizure while driving could create a serious roadway hazard and risk of loss of power in traffic. Additionally, Hyundai dealerships have advised that replacement engines for this vehicle are no longer readily available. I believe Hyundai should further investigate whether the 2017 Tucson 1.6T Gamma GDI engine should be included in existing engine defect warranty extensions and/or recalls.

The vehicle has experienced life-threatening safety defects during operation; shaking, hesitation, and stalling in high-speed traffic. The vehicle unexpectedly stalled/lost power while driving, putting myself and others in direct risk of collision. The Hyundai dealership claimed it needed an Actuator Gasket replacement, Throttle Body replacement, and ECM/TCM update. The vehicle had NO warning lights until after it stalled, then warning lights illuminated briefly. The Hyundai dealership claimed repairs were "completed" 5/8/26; within 72 hours of "completion" the vehicle's symptoms reappeared. The Hyundai Executive Case Manager has made NO efforts to resolve this LIFE-THREATENING SAFETY issue. This has put myself and children in danger and is legally unsafe to drive.

My 2017 Hyundai Tucson is experiencing dangerous, sudden engine stalling, which are symptoms directly matching Service Campaign T1B. These critical safety issues surfaced following a total engine replacement in June 2025. Despite the vehicle being within the 12-month/12,000 mile workmanship warranty, the dealership is refusing to honor this coverage or offer goodwill assistance. My claim is based on a documented pattern of physical and technical negligence: - Failure to Update Software: The dealership failed to perform the mandatory ECM/TCM software integration (Campaign T1B) during engine swap, which is required to prevent the exact stalling I am now experiencing. - Dismissal of Warning Lights (Code P0456): One day after the engine replacement was “completed,” I returned to the dealership because the Check Engine Light illuminated with Code P0456. This was dismissed by the service provider without a proper diagnostic resolution, despite being a direct indicator of improper vacuum line reconnection during the engine installation. - Mechanical Negligence (Coolant Leak): Post-engine swap, the vehicle developed a coolant leak, which was a direct result of improper reassembly. Additional proof of the lack of due diligence during the repair. The lack of follow-through, combined with the dismissal of a life-safety defect and poor physical workmanship, suggests a total failure in the case management process. I am urgently requesting assistance to resolve this hazardous situation.

The panoramic sunroof glass suddenly shattered while the vehicle was being driven on the interstate, with no visible impact, object strike, or prior damage observed. The component involved is the sunroof glass panel, and it has already been removed and replaced through insurance repairs, so it is not available for inspection (however, pictures are available upon request). The incident created a loud, explosion-like sound and resulted in glass fragments falling into the interior of the vehicle, including onto the driver and the front-seat passenger, causing minor injuries. This also created a significant safety risk due to driver distraction, panic, and the potential for more serious injury while the vehicle was in motion at highway speeds. The issue has not been reproduced or independently duplicated by a dealer or service center; however, it was inspected and documented by the insurance company and repair facility during the claims and repair process, which confirmed that full glass replacement was necessary. The vehicle or component has been inspected by insurance representatives and a repair shop, but it has not been inspected by the manufacturer or law enforcement. There were no warning lamps, dashboard messages, or any prior symptoms indicating a problem before the failure occurred, and the sunroof appeared to fail suddenly and without any advance indication while the vehicle was in motion.

The vehicle has a difficult time turning over when cranking, the RPMs are sticking and the car periodically shuts off at red lights. Several warning lights pop up when it won't crank and then other warnings when the car just completely shuts off at red lights. I drive the interstate in [XXX] daily for work, so with the engine stalling my safety is at risk every time I drive it. Likewise when it won't crank, my safety is at risk. I had two Hyundai recalls updated in my car in 2022, Hyundai Recall 209 which was a connecting rod bearing test and my car passed so they installed the other Hyundai Recall 966 which was software update for the knock sensor detection system to alert the driver of future issues. Those issues are now current. The software is detecting a critical failure which is why the car is shutting off - entering limp mode, or the engine is failing. On April 9th through the 11th, 2026 my vehicle was inspected by a Hyundai dealership, where a technician identified a developing engine concern and advised me to continue driving the vehicle.

My Hundai Tuscon 2017 was making a whurring sound on the highway, at which time my RPM's were not going over 3. As I was looking for places to pull over on the highway, I heard a loud 'pop' and then my engine started smoking and an intense rattling ensued to where I could hear a series of parts drop out of the bottom of my car. My car began smoking and the engine completely stalled just in time for me to make it to the side of the road. I took it to a local shop for repairs and they showed me three holes in my engine.

The vehicle was taken back to the dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 67,700.

The contact owns a 2017 Hyundai Tucson. The contact stated that the vehicle was consuming an excessive amount of engine oil. There was an abnormal knocking sound coming from the vehicle. There was no warning light illuminated. Due to the failure, the vehicle was towed to a dealer, and the excessive oil consumption was confirmed. The contact was informed that the vehicle was included in NHTSA Campaign Number: 21V727000 (Engine), and the engine was replaced. The vehicle was repaired, and a family member retrieved the vehicle and drove it to the residence without failure. Several days later, the family member started the vehicle, and fuel started pouring out from underneath the vehicle. Due to the failure, the vehicle was towed back to the dealer and was diagnosed the vehicle with an O-ring failure inside the fuel injectors. The dealer repaired the O-ring, and the contact picked up the vehicle from the dealer. Soon after retrieving the vehicle, fuel started pouring out from under the vehicle at start-up. The vehicle was towed back to the dealer and remained with the dealer. The manufacturer was notified of the failure, and a claim was filed. The vehicle was not repaired. The failure mileage was approximately 68,000.

the door latches are no longer opening the doors from the inside of the vehicle. This started with the passenger rear and now is effecting the drivers door. The only way to get out of the vehicle is to crawl over the seat to get to a door that is still operational. No warnings, just doesn't open when you pull on the handle. Will be making an appointment with a local dealer/service dept but given the security concerns this is being reported here as well.

The contact owns a 2017 Hyundai Tucson. The contact stated that while starting the vehicle and driving at an undisclosed speed, there was an abnormally loud grumbling sound coming from the engine. There was no warning light illuminated. The contact stated that the vehicle unexpectedly entered LIMP Mode. There was no warning light illuminated. The vehicle was towed to the dealer but was not diagnosed or repaired. The manufacturer was made aware of the failure and informed the contact that documentation of previous oil changes was required. The contact stated that the manufacturer accused the contact of a lack of maintenance, which was associated with the engine failure. The failure mileage was approximately 98,000.

To Whom It May Concern, I am writing to formally escalate an unresolved safety issue involving my 2017 Hyundai Tucson (VIN: [XXX] ) that has now been ongoing for over two years. I have made repeated attempts to complete a safety recall repair through multiple authorized Hyundai dealerships, including Hyundai of [XXX] and Hyundai in [XXX] . Despite scheduling several appointments, I have consistently been turned away, had appointments effectively canceled, or been told that no one is available to perform the repair. This has occurred across more than one location and over an extended period of time. This is unacceptable. A federally mandated safety recall especially one involving the engine is not optional and must be completed within a reasonable timeframe. The continued failure to complete this repair places me at risk and reflects a serious breakdown in both dealership accountability and corporate oversight. Additionally, my vehicle has experienced significant paint chipping. While I understand this may not be a safety recall issue, it has affected the overall condition and value of my vehicle. Given the prolonged delay and inconvenience I have experienced, I am requesting that this concern also be reviewed for potential goodwill repair or coverage. At this point, I am requesting immediate action: Assignment of a case manager A confirmed and honored appointment date for recall repair at a dealership that is able to complete the work Written confirmation that the repair will be completed without further delay Information regarding a loaner vehicle or transportation if the repair requires extended time Please note that I am filing a formal complaint with the Illinois Attorney General’s Office due to the repeated failure to complete a federally required safety recall. If this matter is not resolved promptly, I will pursue additional consumer protection and legal remedies. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My ABS has been sticking and finally the pad broke off. my car made a squealing noise everytime I drove it. I had parked in my driveway and there was a piece of metal on the ground. I showed it to my son, he took the tire off and said it held my ABS Brake pad on to my Driver side rear. He is a master tech for Subaru. I just haven't had time to take it into Hyundai. It has stopped squealing, but my ABS brakes no longer work.

This unresolved issue has created serious safety risks. On two separate occasions, my vehicle lost power while crossing the Leo Frigo Bridge in Green Bay—an extremely dangerous scenario for both my family and other drivers. Most recently, within just ~40 miles of picking up the vehicle from service, the issue recurred. The service department reported finding oil on the ignition coils—symptoms consistent with known and documented warranty concerns such as: Valve cover gasket leaks Spark plug tube seal failure High-pressure fuel pump gasket leaks The vehicle has been brought multiple times to a certified Hyundai dealership for recurring problems including power loss, poor engine performance, and excessive oil consumption. Despite these repeated service visits, the underlying issue has not been properly addressed. I have now been informed that I am responsible for diagnostic charges—even though the vehicle is covered under the TXXM Engine Warranty Extension / Powertrain Limited Warranty due to known oil consumption-related defects.

In April of 2023 while driving I heard a pop noise and my engine started smoking. A connecting rod had broke in half and went through my oil tank. My 2017 Hyundai Tucson had only 54k miles. I was denied warranty and my vehicle was branded maintenance neglect due to lack of proof of oil change but when I sent the dealership I purchased my vehicle from the all my oil change receipts in August 2023 I was still denied and my car is still branded today without explanation.

The turbocharger on my 2017 Hyundai Tucson 1.6T has failed three times within one year. Most recently, the dealership diagnosed the turbo’s wastegate actuator as being completely open, resulting in severe power loss and unsafe driving conditions. The replacement turbo from an authorized parts supplier is still under a 5-year warranty, and the dealership confirmed there were no oil feed or installation issues contributing to this repeated failure. Component/System Failed: Turbocharger (wastegate actuator stuck fully open). The failed turbocharger is available for inspection upon request. Safety Risk: The vehicle experienced severe loss of power while and also the dealer made me aware there is a valve stuck in the turbo itself and if i drive it it could blow the motor up, which made merging and accelerating unsafe and could have resulted in a collision. The lack of engine power when entering traffic or climbing steep grades put both myself and other drivers at risk. Dealer Confirmation: The issue has been confirmed and documented by a Hyundai dealership service center. This is the third turbocharger replacement within one year for the same vehicle, indicating a potential defect or underlying issue. Warning Lamps/Symptoms: The check engine light illuminated (P0299 – Underboost) prior to the failure. I also experienced significant loss of acceleration and increased fuel consumption. These symptoms began days before the dealership confirmed the wastegate actuator failure. Resolution Sought: I am requesting Hyundai Consumer Affairs review this case due to repeated turbo failures, potential underlying defects, and financial burden. I would like to know what Hyundai can do to address the repeated turbocharger failures and associated labor costs.

I own a 2017 Hyundai Tucson with the 1.6L turbocharged engine. My vehicle is experiencing serious and potentially dangerous engine issues, including knocking, loss of power while driving, sudden engine stalling, and low oil pressure. These problems have worsened over time and now occur regularly during normal operation. The vehicle has stalled in traffic on multiple occasions, creating a significant safety hazard for myself and other drivers. I am aware of an existing recall (21V-727) for 2017 Hyundai Tucson models with the 2.0L engine related to premature engine bearing wear, and the symptoms I’m experiencing appear to be identical — yet my 1.6L turbo model is not included. I strongly believe this issue may also affect the 1.6T engine variant and poses a serious safety risk. I am requesting that NHTSA investigate whether the 1.6L turbocharged engine used in this model year should also be subject to recall due to the same type of internal engine failure. I am currently pursuing diagnostics and have contacted Hyundai to request assistance, but the cost of repair and potential danger while driving remain urgent concerns. Please take this report into account as part of your investigation.

The vacuum pump cap was diagnosed as the issue. All the lights came on the dash. I lost power steering and speedometer. There has been recalls for other years.

The contact owns a 2017 Hyundai Tucson. The contact stated that while attempting to accelerate, the transmission failed. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired, but the failure reoccurred. The contact stated that while driving approximately 25-30 MPH, the vehicle was making an abnormal rattling and knocking sound that was coming from the engine while accelerating. The transmission was shaking continuously while driving at 10 MPH. The vehicle was taken to the local dealer, where it was diagnosed with camshaft and engine failure and needed a cam finish over an advanced timing system overhaul. The contact was informed that the camshaft, CVT, timing chain and tensioner, front valve cover and valve cover gasket, turbocharger, turbocharger gasket, and turbocharger lines needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 92,000.

My door to drivers side only fully unlocks from the inside. When my door is locked it now requires me to climb through another door of my car and pop open the drivers door. If I were to get in an accident people wouldn’t be able to get me out if I was incapacitated.

Without any warning, the engine stalled out going through an intersection.

The vehicle suffered extreme oil consumption while under the 'famed' 100k mile warranty. Tests were performed at the dealership confirming excessive oil consumption. Hyundai USA refused to service the issue claiming my personal service records did not meet their standards of responsible maintenance. At 108k miles the engine failed while on the interstate in CO. Cylinder 2 had blown and the dealership noted the towed vehicle was low in oil. The engine failure is a direct result of excessive oil consumption, something that hyundai has been aware of and has chosen to fight against owners damaged vehicles, rather than remedy the issue. Hyundai has faced class action suits and settled on these, yet still has not admitted fault. This issue poses a safety hazard for owners who may suffer catastrophic engine failure while driving.

The controls (buttons) on the right side of my steering wheel progressed from slow to respond to completely unresponsive, and then the driver airbag light started coming on. At first it was intermittent, then constant. I didn't expect those two issues to be related but did come to learn it was the clock switch. According to my Hyundai dealer, this is a known issue in several other years/models of Hyundais and they have extended those warranties, "but it hasn't reached the Tucson yet". I was told that either 1 - my airbag wouldn't deploy or 2 - it would deploy randomly when I was driving the vehicle. I spent nearly $1000 in diagnostics and repairs.

The engine blew. It had to be replaced at my costs because hyduadai does not warrant when a car changes hands. It has 81250 in miles. This is happening to lots of people. It’s a 1.6 L engine. The 2.0 has a recall. But the 1.6 needs to be recalled also. Something needs to be done.

The contact owns a 2017 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact became aware of an abnormal knocking sound. No warning lights were illuminated. The contact stated while driving uphill, the vehicle stalled and lost motive power. The vehicle was taken to the dealer; however, the failure was not duplicated. The dealer requested an oil consumption test. The oil consumption test was performed and indicated that the engine was consuming an excessive amount of engine oil. The contact stated there was no warning light to indicate that the oil pressure was low. The contact stated that the oil was six quarts low. The failure was persistent. The contact stated that there were several failures reported to the dealer. The contact stated that while driving uphill, the vehicle stalled and lost motive power. The vehicle was towed to an independent mechanic. In addition, the contact stated that the abnormal knocking and ticking sound was persistent. In addition, the contact stated that the engine was six quarts of engine oil low every two weeks. The vehicle was taken back to the dealer. The contact was informed that the cause of the failure was not identified. In addition, the dealer requested an engine replacement due to the persistent failure. The vehicle was not repaired. The contact stated that due to the persistent failure, the vehicle had been taken to the dealer several times. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 86,790.

The engine in my 2017 Hyundai Tucson Limited failed at approximately 111,000 miles. The vehicle began to run roughly, misfiring and losing power with no warning lights or prior indication of an issue. Within days, the vehicle became undriveable and had to be towed to a dealership. The dealership diagnosed the issue as a cylinder misfire due to internal engine damage caused by excessive oil consumption. They confirmed the only solution was a full engine replacement. I was told this issue is not currently covered by recall, despite its similarity to known engine defects Hyundai has recalled in other vehicles. This failure posed a serious safety risk. The vehicle stalled and lost power while driving, making it dangerous to accelerate or keep pace with traffic. Fortunately, the failure did not cause an accident in my case, but it easily could have in different circumstances. There were no dashboard warning lights, oil pressure warnings, or check engine indicators before the symptoms began. The oil level had not been excessively low, and the car had been well maintained. I have opened a case with the manufacturer, but assistance was denied due to mileage and ownership history. This appears to be part of a broader pattern of engine failure in similar Hyundai models. I am reporting this in hopes it contributes to further investigation and potential recall expansion.

We purchased this car brand new in 2017 for my late mother.... It had 12000 Miles on it and started shaking intensely last year. We took it into Tuttle click Hyundai multiple times and they said it was fine.... Charged us several thousand and it continued to shake so we took it back multiple times. They have taken tons of our money and the car shakes as it drives.... Yesterday we found out that there was a major recall on this engine and we were never notified.

My engine was recalled and they inspected it and said it was fine in 2023. Fast forward to June 2025, My engine failed. I took it back to the dealership and they tested it and said "it was not bad enough to be fixed under the recall." Before I took it the dealership the check engine light was on, reduced power when accelerating, knocking noise from the engine that increases when the rpms increase, and the oil pressure light is flashing. Upon taking it to the dealership the check engine light has been turned off, but all the other issues still remain. All of these issues were components to the recall. I have called Customer Care and they assured me that it would be fixed at no cost under the recall, and then I requested a different dealership due to terrible customer service at the prior dealership. Customer Care then contacted prior dealership, and went based on the incorrect findings of the dealership, they are refusing to fix my engine that is under recall. Because they inspected it in 2023 they marked the recall campaign as closed.

My 2017 Hyundai Tucson 1.6 liter is experiencing severe engine issues that closely mirror those subject to recent class action lawsuits. The engine exhibits excessive oil consumption. I have experienced a sudden loss of power on roadways in traffic as well as on the highway. This issue happened just today. Unfortunately due to a loss of smell, I have been unable to smell if there has been burning oil, however in between my last two oil changes (I only bought the car in October) I had to go it to get it refilled or refill it myself. I use full synthetic oil as well. I brought it into a reputable mechanic and I have been told if I continue to drive the vehicle the excessive oil consumption will lead to premature engine failure, potentially causing a dangerous stall or accident, putting myself and other motorists or pedestrians at risk. The mechanic received codes P0420, P0300, P0302, P0303, and P0304. They were able to conclude oil consumption based on the low amount of oil in the vehicle, the spark plugs being oil fouled, the misfiring on three cylinders, and the P0420 code. I called customer service, the Hyundai dealership in Clive, IA, and the contact for the class action lawsuit and litigation II. I was informed my VIN number was not part of the current recalls or class action, however the symptoms are identical to those widely reported. In the litigation my make and model are mentioned, Hyundai Tucson 2017, however it is listed as the 2.0 liter engine. My engine is mentioned, the 1.6 liter, in at least one other vehicle. I believe this vehicle was only excluded by a lack of representation at the time of the litigations. From my call with the dealership, and in research I am not the only one experiencing this problem. While I was lucky enough not to have been harmed, this has the potential to cause great harm. As someone who works for a DOT, safety first is in everything I do. I believed this necessary to report for the safety of all those involved.

I have a 2017 Hyundai Tucson with approximately 120,000 miles. The vehicle had issues with oil consumption and jerking when put into drive. I took the vehicle to the dealership to be checked and was told it was fine. I recently was driving at 70 mph when the engine light came on and lost power. I had it towed to a mechanic that checked and cylinder #3 had lost compression. After finding this out I did an internet research and found that this is a common issue with this motor and vehicle. My vin is not included in the recall but Hyundai has replaced other engines in “goodwill” when the vin number was not included. One search shows that it usually happens from 120,000 to 150,000 miles. After the mechanic looked at the vehicle, Hyundai instructed me to take it to a dealership. After another tow to the dealership they said it was only the spark plugs but upon futher investigation they found that the cylinder was damaged with scoring to engine. The cost for a used engine with 54,000 miles is 10,000 and is more than the value of the car and the remaining loan amount of 10,000. So far we are out approximately 300.00 in towing fees. The dealership has not yet billed us for the checking they have done. We have contacted Hyundai with a response of no help to replace the engine even though the company has helped others in our situation. We haven’t replaced the motor due to the amount owed, cost of used motor vs the value of the vehicle. The safety of the vehicle is very questionable due to the high incidence of this happening and there could have been catastrophic consequences if I would not have been able to pull off the road.

UNKNOWN There is a issue with paint on the car. The paint is white and is chipping on hood, top of car and back of car. The car looks terrible with a cheap paint job.

On [July 4, 2025], while driving, my vehicle experienced a sudden loss of power followed by smoke and flames coming from the engine compartment. The fire required emergency response and caused significant damage to the vehicle. Thankfully, no one was injured, but the incident posed a serious risk to my safety and others on the road. I had not received any prior warning signs such as engine knocking or warning lights. The fire appears to be directly related to the known defect outlined in Recall 209. I am requesting that NHTSA investigate this incident and ensure Hyundai is held accountable for the full scope of this defect, including fire risk. I am also seeking assistance in ensuring Hyundai provides appropriate compensation or resolution for the damages caused.

The car has issues with major oil consumption, and a chatter engine noise, also has issues with acceleration. Oil will run dry if not topped off every 3 weeks.

Power windows will go down by driver buttons but driver buttons will not work to make windows go back up. Engine is stalling, can smell exhaust, manifold is said to be needed to be replaced. Burns oil badly.

Vehicle Make/Model/Year: Hyundai Tucson 2017 NHTSA: Recall Number 21V727000 Description of Problem: My vehicle is affected by a known safety recall related to the engine (likely recall campaign P1326 or similar, affecting Hyundai engines). I contacted the authorized Hyundai dealership to schedule the recall service. However, the dealership is requiring me to pay out-of-pocket for parts and/or tests — specifically, they mentioned charging for testing engine gaskets/joints — before confirming whether they will replace the engine under the recall. The recall notice clearly states that diagnosis, testing, and any necessary engine replacement should be done at no cost to the consumer. The dealership’s request for payment appears to be in violation of federal recall laws. I am being forced to delay this safety repair because I cannot afford these unexpected charges, which I believe are not allowed under NHTSA recall policies. This compromises my safety and could affect many other consumers in the same situation. Please investigate this dealership’s handling of the recall. I am requesting that Hyundai be held accountable for ensuring proper and legal recall service.

limp mode check engine light code p1326

My engine needs to be replaced. Out of nowhere it failed. No stuttering, no stalling, no check engine light or any other warnings. Just failed.

While driving under normal conditions, the engine began misfiring and losing power. Inspection revealed that two of the spark plugs had suffered a broken ceramic insulator, which likely occurred during a pre-ignition or detonation. As a result, the ceramic insulators were pushed through the engine causing at least one of the exhaust valves to burn leading to loss of compression resulting in engine failure on the highway. This engine has no current recall, despite numerous similar complaints. Hyundai has issued detonation-related recalls for other engines (like the Theta II), yet the 1.6L Turbo GDI engine in this Tucson is also experiencing similar failures. At the time of this complaint there are 955 complaints in the NTHSA database about this vehicle with more than half citing engine failure issues — many of them sudden and severe failures while driving. This creates both a safety risk and an excessive financial burden. These failures occur without warning and can leave the driver stranded. It is concerning that Hyundai has not acknowledged a defect pattern, despite consistent failure modes being reported across this engine type. I am requesting that NHTSA investigate the 1.6L Gamma II Turbo engine for potential systemic detonation or pre-ignition issues that can lead to severe engine damage. A recall or special service campaign should be considered, and Hyundai should be held accountable to cover these repairs.

The vehicle is experiencing severe engine shaking and misfiring during operation. Initial diagnostics confirmed that the spark plugs and ignition coils are functioning correctly and are not the source of the problem. A compression test revealed that two cylinders have no compression, indicating a likely internal engine failure. Potential causes include damaged or worn piston rings, valves, or a blown head gasket. This condition results in rough idling, reduced power, poor drivability, and potential long-term engine damage if not addressed promptly. Immediate engine repair or replacement is required.

While driving, the vehicle started knocking and jerking, lost power and began to run roughly. The check engine light initially flashed and then turned solid before the vehicle shut off. The next day, I took the vehicle to the dealership for a diagnostic after experiencing problems with knocking when the check engine light illuminated. The codes were P302 and 304 indicating misfiring. The diagnostic tech wrote the problem up as having oil in the cylinder and suggesting engine/turbo replacement for approximately $15,000.00. The engine has less than 100,000 miles. I asked about the 10/100. After inquiring about the recalls for GDI engines in the 2017 Tucson for rods causing engine fires due to oil leaking into the cylinders, the service agent stated that it was only the 2.0 and not the 1.6 with recalls. I said sir it is the same issue: high oil consumption, sputtering and knocking, check engine light indicating misfire. Now the oil is accumulating in the cylinders. He stated that because I am the secondary owner neither the dealership nor Hyundai will correct the problem. However, if I was the original owner the powertrain warranty would cover the repair. The problem with the 2017 GDI, DCT in the Tucson is a safety issue for all owners. Escalated the issue to Hyundai Motor America, agent Kyrillos, who said that he would contact the dealership to check for prior authorization with the dealership to see if they would cover it under the recall. After numerous calls (on my behalf) and finally speaking with Kyrillos, I was advised that the dealership denied the repair. I requested supervisor contact and have not had any further communication from the company. I did send a follow up email asking when I could expect to hear from them.

The contact owns a 2017 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the low oil light illuminated, and the vehicle was shaking abnormally. The contact added oil to the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed with oil shavings in the oil pan and engine failure. The contact was informed that the engine needed to be replaced. The dealer was made aware of the failure but provided no assistance. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 101,000.

Car cuts off when driving the speed drops down automatically stops the dash lights go out and can’t start it right away

I was returning home from a 224 mile trip. I was driving 65mph with the AC on low. Vehicle started slowing and losing power. I pulled over at the next possible location when I noticed the engine light was blinking then stayed solid yellow. I tried to rev the engine a few times only to be met with engine shutter and misfire. Had to have the vehicle towed the remaining 65 miles home. Took the vehicle to my mechanic where he stated cylinder 3 and 4 misfiring and told me this is a common problem with this vehicle. After doing my own investigations, I see this vehicle has an extensive history of the same problem from several other people. But yet no recall.... Why?

The contact owns a 2017 Hyundai Tucson. The contact stated while driving 35 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The vehicle hesitated, and the contact pulled over to a parking lot. The check engine warning light illuminated. The vehicle was taken to O'Reilly's and was diagnosed with spark plug failures. The vehicle was taken to Meineke, where it was diagnosed and determined that the engine had failed and needed to be replaced. The vehicle was towed to the dealer where it was confirmed that the engine had failed and needed to be replaced. The engine was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 100,000.

It is my belief that the engine is failing or has something wrong, due to an engine recall. I started having issues with acceleration and took it to a local mechanic who advised it was an engine issue and needed to be taken to the Hyundai dealer asap. As of today, May 27, 2025, it was taken to Autonation Hyundai in Columbia, SC who is alleging that all engine recalls related to my vehicle are not covering any engine issues. I have had this car for quite a while and have never had any issues until now. Multiple diagnostics have been performed.

There is an excessive engine oil consumption on the 1.6L turbo charged motor. Motor oil is completely depleted between recommended oil changes. It is a necessary to add roughly 1qt of oil per 1,000 miles driven, between oil changes, in order to maintain safe oil levels. No signs of leakage, therefore oil is burning at an unsafe rate.

In February of 2025, my oil lamp warning light came on. My husband checked the oil dipstick and noticed that it didn't have any oil on it. There was a visible burn mark as well. I called my local Hyundai dealer to schedule an appointment to see why my car was burning oil like that as it was not due for an oil change. The appointment was made for February 20, 2025. My car at that time had 79,803 miles on it. The Hyundai dealer suggested performing an engine combustion cleaning service, per Hyundai, to see if it would "fix" the problem. They also went ahead and did an oil change. After these services were done, I was told to bring the car back in after 1,000 miles. Hyundai's guidelines are that they allow 1 quart of oil loss per every 1,000 miles. I brought the car back to the Hyundai dealer after 1,000 miles and that was in April of 2025. I was told that my vehicle passed the inspection. The oil level on the dipstick was in the "normal range." After a few weeks, my husband checked the oil level again just to make sure the engine wasn't burning any additional oil since we were not convinced that the engine combustion cleaning service solved the problem. He checked it on May 11, 2025. The dipstick showed that it was below the L. I called the Hyundai dealer once again, and they were able to get me in on Tuesday, May 13th. My mileage was 81,792 on the day I brought it back in. They confirmed that it had burned over 2 quarts of oil in less than 2,000 miles. That is more oil consumption than Hyundai "allows" per their 1 quart of oil for every 1,000 miles rule. The dealer put in a request to Hyundai for a new engine replacement and I was denied due to my vehicle having no warranty.

The power steering of the vehicle suddenly stopped working. We had the car towed, and after inspection we were told that the steering column had failed. We were expected to purchase a new original part from Hyundai, which we did. After waiting a week, we were told that the replacement that was sent did not work and was defective. This has happened again and again, and we are currently waiting for our 4th part from Hyundai. Hyundai corporate told our auto shop that they "opened a case" to see why these parts are defective. I'm hoping that they eventually get to the bottom of this and can fix our Tuscan. We were lucky that our steering column failed on the driveway at our home, but I would imagine it could case quite a bad accident if power steering went out suddenly on someone else.

Blind spot warning stopped working due to electric issues. Engine started miss firing causing a turn over issue and loud knocking. Brought to auto shop and was diagnosed that engine is failing.

1)Component that failed: Engine 2)Driving 75 miles on the interstate in traffic and suddenly losing speed was very dangerous. 3)Yes, the issue is still occurring, even worse now as my vehicle shakes just starting the engine. 4) The mechanic has inspected, diagnosed and attempted to repair. However due to the condition of the engine, and the cost of replacing it; fixing may not be an option. 5)The engine light began flashing and then went off; then back to steady on. I purchased this 2017 Hyundai Tucson used just 4 years ago. Everything seemed to be working just fine, I've had regular oil changes. On Saturday, May 10, 2025, as I was driving on the Interstate with my cruise control set, I began to lose power and my speed slowed. I took my car off of cruise control and pushed on the gas pedal to gain speed and my car started to shake and it struggled to pick up speed. My mechanic has changed the spark plugs and performed a BG upper engine induction cleaning; did compression testing and leak down testing. He found that cylinder 4 has no compression. In addition to that, he noticed there was oil on the spark plug. I had my oil changed 3 months ago, and less than 3,000 miles - my engine is burning up the oil to the point where the oil level is extremely low. I have now found out that this is a known issue with this type of vehicle. I'm told it's $10,000 to replace the engine. I have no warranty coverage since I'm not the original owner. I was not aware of the class action lawsuit that was settled last year. I'm extremely upset that Hyundai has not recalled ALL the engines for this make and model of vehicle as it seems EVERYONE has had engine problems.

Purchased this in June of 2024. Ran fine until August 19th 2024 when I was returning to work from my lunch break. I went home for lunch and everything was fine. On the way back, I was pulling out into highway speed traffic and while merging, the engine just stopped. No warning lights or anything. It just stopped running. The vehicles behind me luckily were able to see what happened and get around me without incident. Once I was able to coast back to a safe area, I proceeded to try to restart it with nothing but a click as a response. Tried a few more times with same result. Called roadside assistance and proceeded to check under hood. Found oil stick barely showing any oil when just under 2 months ago it was full, and I had not seen any warning light indicating low oil. Took oil cap off and felt what was inside and found metal shavings in oil. Roadside showed and pretty much confirmed the metal shavings and my worst fear. Still had it taken to a Hyundai dealership where they told me the motor was seized at it would be $13,200 to fix. Asked about the existing class action suit and pretty got told my engine wasn't part of it. After looking at all the complaints here, not seeing how they CANT classify this as a major issue. Still fighting with dealership I purchased from to get something done.

The transmission failed, and it's only at 70k. This was only diagnosed AFTER being told that my dual clutch was faulty. I had that replaced, only to be told that my actuator was faulty and NOT the clutch, after haviing paid for the replacement. Now, the vehicle will barely move with rpms through the roof. So not only was Ithe vehicle misdiagnosed TWICE, the cost of repairs was sky high! This could have been avoided. I contacted the dealerships, at they advised that they did everything as hyundai instructed them. Well, hyundai was wrong, and now my vehicle doesn't even work.
