Hyundai Elantra 2022 — Problemas reportados

My vehicle did not have any warning lights or issue lights on the dashboard at the time of crash. We were at a full stop on the highway when a car rear ended us going 50-70MPH. The driver had a broken left clavicle. No air bags deployed despite the severity of the crash.

Hyundai's forward collision warning light is on and won't allow me to use cruise control. I've tried cleaning the area, but still won't turn off. It did turn off for about an hour and while on the freeway using cruise control it came back on.

Braking system failed to brake properly. It feels like even though the brakes were pressed all the way down, the car did not brake as it should. Also, the automatic collision avoidance system did not respond.

I own a 2022 Hyundai Elantra N Line. The HVAC system began malfunctioning when the center/forward-facing dashboard vents stopped producing airflow, while the side vents continued to work. Changing the HVAC mode does not properly redirect airflow to the center vents as intended. The vehicle was inspected and diagnosed, and I was informed that the ventilator lever/mode mechanism is broken or not functioning properly. This appears consistent with a known issue described in Hyundai Technical Service Bulletin 25-HA-001H/26-HA-001H concerning the ventilator lever and loss of airflow from the forward-facing center vents. This failure affects my ability to properly control where air is directed inside the vehicle, including directing airflow toward the windshield for defrosting/defogging. This could potentially reduce visibility in conditions where windshield defrosting is necessary and therefore create a safety concern. The problem has been confirmed through a vehicle diagnostic inspection. The vehicle/component is available for inspection upon request. I have also found other Hyundai Elantra owners reporting similar loss of center-vent airflow and HVAC mode-control problems. The issue occurred without a collision or other known event that would have caused the component to fail. The repair is also unusually labor-intensive because the failed ventilator lever is located behind the dashboard and requires extensive disassembly just to access the component. I was informed that the repair would require at least 14 hours of labor, resulting in an extremely high repair cost for what is essentially a small mechanical component. The amount of labor required to reach and replace the lever makes the repair disproportionately expensive. Additionally, I have encountered multiple other Hyundai Elantra owners reporting the same or very similar symptoms, including loss of airflow from the center/forward-facing vents while the side vents continue to function. Suggests occurring issues.

Horn not functioning. Engine mount needs replacement.

Transmission slippage, near failure, unable to accelerate safely past 20mph. Need to floor the gas peddle which causes me to go over the desired speed.

I own a 2022 Hyundai Elantra with only 72,000 miles my check engine light came on for the code p048900 for the Egr valve. It is no longer covered by any warranties but other year models have been recalled due to the same issue.

Federal Safety Recall Fraud and Vehicle Endangerment Report Vehicle: 2022 Hyundai Elantra Blue Hybrid | Involved Dealerships: Earnhardt Hyundai North Scottsdale & Larry H. Miller Hyundai Peoria This complaint documents severe federal safety recall fraud and mechanical endangerment by authorized manufacturer franchise dealerships. In April 2025, Earnhardt Hyundai took physical possession of my vehicle for a federally mandated Hydraulic Electronic Control Unit (HCU) braking/cruise control safety recall. Staff verbally verified the recall was complete, but the physical invoice and subsequent written email admission from Service Drive Manager [XXX] confirmed the safety repair was completely omitted with "no excuse."To resolve this braking risk, on April 22, 2026, I brought the vehicle to Larry H. Miller Hyundai Peoria to have the uncompleted HCU safety recall corrected. Subsequently, on June 17, 2026, I returned to the Peoria facility for a warranty deck lid repair and a scheduled oil change.Upon releasing the vehicle on June 17, the Peoria service department actively jeopardized my hybrid engine integrity by installing an incorrect, out-of-spec oil fluid weight (5W30) and releasing the vehicle with a completely loose, unsealed engine oil cap. This gross negligence forced me into a dangerous 140-mile high-altitude mountain highway transit ([XXX] to Flagstaff) with a compromised engine bay, creating an immediate engine fire hazard and risk of sudden highway power failure. The loose cap and incorrect fluid were independently verified and caught on video by Milestone Auto Repair in Flagstaff.The manufacturer's franchise network is falsifying federally mandated safety recall records and releasing vehicles in life-threatening, non-compliant conditions. I'm requesting an immediate NHTSA investigation on both dealerships. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My car was hit from the rear by another vehicle while I was traveling with my [XXX] daughter. The impact was very strong, and one of the tires came off. None of the airbags deployed, and I feel there may have been an issue with the airbag system. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Description of Incident: The vehicle is experiencing significant engine oil dilution by gasoline. Upon inspection of the dipstick, the oil level is consistently found to be well above the "Full" mark, and the oil emits a strong, pungent odor of raw fuel. This indicates that unburnt gasoline is bypassing the piston rings and entering the crankcase during normal operation, particularly in colder temperatures or during hybrid engine cycling. Safety Risk: The dilution of engine oil with fuel significantly reduces the oil's viscosity and lubricating properties. This creates a high risk of premature engine wear, rod bearing failure, and sudden engine seizure or stalling while the vehicle is in motion. A sudden loss of motive power at highway speeds poses a severe crash hazard to myself and other motorists. Attempts to Correct: I have noted that similar Hyundai models using the 1.6L platform (such as the Tucson Hybrid via TSB 23-EE-002H) have received software updates to address this specific issue. However, when contacting the dealer regarding my Elantra Hybrid, I was informed that no such software fix or service campaign currently exists for the CN7 Elantra model, leaving the safety defect unaddressed. Expected Resolution: Hyundai should be required to issue a recall or technical service bulletin for the Elantra Hybrid to update the Engine Control Unit (ECU) logic, ensuring the engine reaches and maintains temperatures necessary to prevent fuel accumulation in the oil.

The contact owns a 2022 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. Additionally, there was an abnormally strong gasoline odor coming from the vehicle. The vehicle was taken to an independent mechanic; however, the vehicle was not formally diagnosed. The contact was informed that there was a crack in the engine, causing a leak. The vehicle was then taken to the dealer, but it was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 23,825.

The contact owned a 2022 Hyundai Elantra. The contact stated while the vehicle was parked, the contact stated that a relative had entered the residence and informed the contact that the vehicle was on fire. The vehicle was unoccupied. The contact stated that no warning lights were illuminated prior to the failure. The fire department arrived and extinguished the fire. A fire report was filed. In addition, the contact stated that the vehicle was parked five minutes prior to the failure. The vehicle was towed to a local tow yard. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to have the vehicle towed to the dealer for inspection. The failure mileage was approximately 40,000.

The horn on my vehicle all of a sudden does not work. Im afraid that i'll be in a accident because im unable to blow it. Plenty times ive almost been in a accident & it was literally nothing i could do because my horn isnt working. secondly, something is going in with the suspension on the right side of my car. Too much rattling noise. I see in the complaints im not the only one having this issue. third but not least, the ac isnt working. blowing out hot air. ive also seen where alot of people is complaining about that Ive had this car only a year and it has too many recall issues.

Vehicle: 2022 Hyundai N Line Mileage at Initial Incident: ~17,000 miles Components Involved: Engine and Engine Cooling; Exhaust System / Emissions; Air Bags (SRS) I am submitting this complaint to document unresolved emissions system and Supplemental Restraint System (SRS) safety concerns involving my 2022 Hyundai N Line, as well as the manufacturer’s refusal to ensure proper diagnosis and corrective action following a documented dealer service error and subsequent warranty repair. At approximately 17,000 miles, a Hyundai-authorized dealership failed to reinstall an engine oil seal during a routine oil change. This error caused rapid engine oil loss at highway speed, activation of the oil warning system, and oil discharge onto the roadway. The incident is documented in Hyundai service records and is not disputed. Sudden oil-loss events of this nature are known to cause latent or progressive damage to internal engine components and federally regulated emissions systems, even when immediate engine failure does not occur. Despite proper maintenance after this incident, the vehicle subsequently set DTC P0420 (Catalyst System Efficiency Below Threshold – Bank 1) at a mileage far below expected durability. Hyundai replaced the catalytic converter under warranty. I requested diagnostic data, inspection findings, and documentation supporting the repair, but the dealership refused to provide anything beyond a basic repair invoice. Immediately following this Hyundai-authorized warranty repair, the vehicle developed a new drivability defect, specifically hesitation during acceleration, which was not present prior to the catalytic converter replacement. This indicates a post-repair nonconformity and raises concern that emissions-related components may not have been fully repaired or that additional systems were affected during the warranty repair process. When I returned the vehicle for evaluation, the dealership stated that it would not diagnose the vehicle unless an acti

There is an issue with mice getting into the front of the car. It smells like urine and is unsafe to breathe. I have cleaned out air filters monthly and find nests every time and have even found a dead mice. My car has nothing that would attract the mice. I have tried everything and spent so much money to prevent this from happening. Apparently with this car it is a known issue, and has not been fixed.

I am reporting a safety-related defect involving the vehicle’s infotainment and forward safety systems. When this occurs, the vehicle also shows a “Check Forward Safety System” warning message. Diagnostic trouble code C162078 is triggered, indicating a front radar out of alignment. As a result, critical safety features such as Forward Collision-Avoidance Assist, Smart Cruise Control, and other radar-based driver assistance systems are disabled. This issue creates a significant safety risk because the driver is not alerted to potential forward collisions and cannot rely on active safety systems. The blank infotainment screen also prevents access to vehicle settings, warnings, and camera functions. In South Korea, this same defect has resulted in an official recall and free front radar replacement and calibration. However, in the United States, customers are not covered under a recall and are required to pay out of pocket for radar realignment or replacement, even though the issue is identical and a lot of time the issue came back 3 months later and customer have to pay out of pocket once again to fix the same issue. Many owners report receiving official recall notices in other markets, while U.S. owners must independently diagnose the issue. Dealers often state that the problem may be caused by radar misalignment after a software update or system fault. In some cases, cleaning or recalibration temporarily resolves the issue, but in other cases, full radar replacement is required. This inconsistent treatment places U.S. consumers at a financial disadvantage and allows a known safety defect to remain unresolved. I am requesting that NHTSA investigate this defect and require the manufacturer to issue a U.S. recall with free repair, calibration, or replacement, consistent with actions already taken in other countries.

My vehicle experienced a sudden and complete brake assist failure, including the emergency brake. I was unable to stop the vehicle, which directly resulted in a collision. Prior to the crash, the car showed no warning lights. After the accident, I had the vehicle inspected at the Hyundai dealership. The dealership stated they could not reproduce the failure and “found no issues,” which contradicts the symptoms. Since the crash, I discovered two Hyundai Technical Service Bulletins that directly match the failure I experienced: TSB 23-01-036H-1 (Relates to HECU/Electronic Parking Brake failure) TSB addressing DTC C1620 (Relates to FCA Sensor/Automatic Braking malfunction) These TSBs relate to brake assist malfunction, emergency brake concerns, and similar stopping failures. The dealership did not disclose these TSBs, did not apply the corrective procedures, and cleared the car as having “no defects.” The dealership wrote “could not reproduce concern” and “no problems found,” despite the vehicle having just been in a brake-failure crash. This brake failure created a major safety risk with potential for severe injury or fatality. I am reporting this because the defect appears unresolved, the dealership denied it, and the TSBs show Hyundai is aware of brake-related issues. I request that NHTSA investigate this brake-system failure as part of a potential manufacturer safety defect. The vehicle is currently secured at the dealership (Lithia Hyundai, Las Vegas) and is available for inspection upon request by NHTSA investigators.

I didn't know the horn wasn't working. I was driving and a vehicle almost backed into me on the drivers door. I couldn't warn them that I was behind them I was fortunate to move before they backed into me. I haven't taken the car to the dealer. I searched on the internet to see if this was an isolated incident and I found hundreds of incidents of people reporting faulty horns on Hyundai vehicles. This should be a safety and a recall issue/

The headlights go off and on randomly It happens during the day and evening I have brought it to the dealer two times and they said after five days they cannot duplicate the problem At night time it is very dangerous when the headlights go off as I drive in a rural area I have submitted daytime photos which shows the malfunction I cannot submit nighttime photos as it is too dangerous The problem occurs daily The vehicle is available for inspection

Horn does not work

I was pulling into a parking spot, moving very slowly, and the car suddenly accelerated. I’m not sure if it was the brakes only because I was slowed down and preparing to stop. I was lucky that I only went into a PVC fence and no one was injured. There was no indication of any sort of a possible problem. No one looked at it because I had no idea that that could be done, and I wouldn’t know where to go.

The car now shows a warning "Check Forward Safety System" and cruise control, understandably does not work. I have not had any collisions or accidents for this to occur. There seems to be no recall from Hyundai, however, this appears to be a safety issue that needs to be addressed by Hyundai.

The contact owns a 2022 Hyundai Elantra. The contact stated while her daughter was driving 63 MPH, several unknown warning lights illuminated, and the message that the vehicle was in neutral was displayed. The contact pulled over to the side of the road and waited for a tow truck to arrive on the scene. The contact stated that a Police Officer showed up on the scene because the vehicle was blocking the right side of the roadway. The vehicle was towed to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure but offered no assistance. The contact was referred to the NHTSA Hotline to report the failure. The approximate failure mileage was 34,000.

FAULTY REARVIEW CAMERA My 2022 Hyundai Elantra sedan rearview camera fails to display clear image or displays no image when shift gear is in reverse position. 2021 and 2022 Hyundai Elantra sedan models were recalled - Recall #271. I need my vehicle repaired but have been told by Hyundai Corporate that my vehicle is not eligible. That is why I am filing this complaint.

Every time I try to use the cruise button I get an error message.

My car has 62,000 miles on it just about three weeks ago. The air conditioner evaporator went out now the car is making a bunch of noise and it’s blowing very hot air. Car should not be having this issue with less miles is this. I took it to the Dealership for a diagnostic check and they told me that this is a known problem with these cars I asked was there a recall on the part due to a failing with less miles, as such The mechanic told me I need to put in a complaint and maybe something will be done so I’m sitting with this car and I literally had to keep the windows down to stay cool

For the past 2 years my Forward Safety System light on has been on in my car. It has turned off and back on repeatedly but has now been on for about 6 months. Hyundai dealerships are estimated a week or two of labor to fix which is extremely expensive for rental cars and outlandish that I bought this brand new and it is already giving me issues. No damage has been had to the car in any way.

I’ve gotten my horn replaced for the second straight time in the past year. Currently at the dealership and service advisors here at West Herr Hyundai in Williamsville state many horns go bad as of today they’ve replaced 7 of them.

My Rear view camara has stop working and there is no recall available for my Elantra by vin number. Is the same problem from the 24V879000 campaign. Please inform me if there is a recall for my car because it’s causing problems in visibility for reverse parking.

Intermittently while driving the vehicle will suddenly engage the traction control (TC)/electronic stability control (ESC). The light flashes for a short period (probably no more than a couple of seconds) and the car slightly jerks to the right. A loud noise is heard when this happens and the brake pedal shakes. Then the light will stop flashing and the car will begin operating normally again. Typically, the problem will reoccur shortly after it happens. I took the car to a dealer, and the dealer was unable to replicate the problem. The service manager stated that there were no codes and no history, and without a code the problem could not be diagnosed. This problem occurred multiple times over the last few months.

I had just drove back home from work and I was driving to pick up my child from his basketball game. I was able to pull out of my driveway and get through two stop signs before I came to a third and needed to make a left hand turn. I stopped and let the cars from the highway pass until it was my turn to go. I was proceeding through the sign and started to turn and in the middle of the turn my vehicle cuts off acceleration and stops moving in the middle of the street and turn. No lights. No warning. Just loses power. I pressed the gas and my rpm’s just reved extremely high. I couldn’t move out of the middle of the street. I pressed the gas again and the car started moving approximately 5-10 mph. Luckily the car driving by didn’t hit me as I was sitting in the middle of the road. I finally got to the side of the road and put the vehicle into park for a couple minutes and tried to take off again. I couldn’t go faster than 5mph at this time. I had to drive back home and by the time I got back I had lost reverse capabilities. Dealer said no recalls and mechanics said not much they can do because there isn’t a code or light on for them to check. I just have a new car that doesn’t drive or go into reverse. I’m going to the original dealer to see if they can help now. I believe this is possibly the transmission but I am not sure.

On June 13 2023, I received an alert on my dashboard that my cruise control was unable to be used due to an issue with the front sensor. The alert went away soon after but then reappeared on August 27th, 2023 the error appeared again. Specifically error code C162078. I wasn't able to get the issue repaired until November 2023, which is also where they replaced my faulty backup camera.

At the beginning of December 2022 (a year after I purchased my brand new vehicle), two of the ignition coils misfired. I was driving down the highway and suddenly my car lost power and then cut off. I was able to start it again, but it would not drive faster than 25mph and would randomly lose power again. On December 7th, 2022 I took it to Hyundai and they were able to replace the two coil packs under the warranty. However, they didn't change the spark plugs (unbeknownst to me), a few months later I decided to change my spark plugs (which had to be purchased directly from Hyundai for $120), all of my spark plugs were completely burnt and looked terrible. There was a caution signal on my dash board and after running an OBD code scanner, one of the error codes that were triggered were "P030400".

On six seperate occasions since I purchased new my traction control light flashed and the vehicle jerked and would lose power. It would then gain and lose power again. Four of these occurances happened in the last few months. It would not subside until I stopped the car. I took the car to the dealer three times and they said they could not duplicate the problem. They also said there were no codes in the car system history that showed any problems. I contacted Hyundai USA for advice. They said to bring it into the dealer and ask them to inspect the car again. That was visit number 3 and the results were the same. The person from Hundai said she would let her supervisor know of my concern for the vehicle safety but I never heard back.

Unknown, "no remedy available"

Rearview camera failure in my 2022 Hyundai Elantra. I need an urgent repair and need to have the rearview camera repair process speeded up because I need to drive at night. I need urgent repair of the rearview camera in my Hyundai Elantra because I do not want to injure pedestrians and do not want to get into collisions that are a direct result of rearview camera failure in my Hyundai Elantra

The back up camera has stopped working. If you read google, yelp, and other forums, a lot of back up cameras have stopped working as early as 24k miles. My vehicle is 2 years old and back up camera has died. I drive a lot of miles for work but cameras do not use mileage. The is a safety hazard as we had a 7 year old killed from a vehicle with no back up camera years ago. I do not agree with having to pay $1000.00 to have this item replaced. Hyundai also did not give me a proper diagnosis. Just need to relace the camera for $980.00 in a link that was a text message.

Rear view back up camera no longer functioning correctly. Has been to dealership where purchased with system update but no remedy.
