Hyundai Santa Fe 2023 — Reported problems

The AWD coupler has failed and the rear wheels feel like they are slipping and catching when I accelerate from a stop, particularly when turning. The car was taken to the dealership and inspected, but no longer under warranty as we are not the original owners.

I bought my 2023 Hyundai Santa Fe at Auto Fair Hyundai in [XXX] in XXX new. This is my third Hyundai from this location over the years. I have always serviced it there ever since I bought it. ( oil changes, tire rotation etc.) Back in XXX while driving home from [XXX] to [XXX] on [XXX] I hit the brakes in the left hand lane, in traffic and my vehicle shut off and wouldn’t restart. Very scary luckily a young man helped push my car off the highway. I sat 5 minutes or so and it restarted. I was told to disable the start/ stop feature which I did. On XXX I went back to auto fair in [XXX] with my issue. I was told I needed a new battery there was corrosion $408. I had them clean the corrosion $95 and I’d bring the vehicle to my mechanic friend where my battery was tested and it was good. I was told to disable the start/stop feature. I went out XXX and forgot to disable the feature and I stalled at 4 way intersection. Stuck there people beeping, traffic backing up and drivers passing by running red lights very frustrated. Yesterday I called Auto Fair service department (on a recorded line) asking if this is an ongoing issue with this make/model. Is there a recall? I was told they haven’t heard about this issue at all and she said good luck. I have 5 year warranty and there is only 24,000 miles on my vehicle. I found a forum online with many others with Hyundais having this issue. This is an accident waiting to happen I’m also reporting it to Hyundai Corporate and Highway safety commission.

While traveling on [XXX] from [XXX] to [XXX] XXX, I initiated the adaptive cruise control. While engaged, with no other vehicles or other impediments on the roadway in front of me, the emergency braking system engaged and attempted to stop the vehicle. The first time this happened, I pressed the accelerator which disengaged the braking action. Later I reengaged the cruise control and after a few minutes, with no traffic near the vehicle, the same action happened again. I disengaged the adaptive cruise control and drove the vehicle manually with no further problems. I have scheduled an examination of the vehicle with a Hyundai dealer but have read of 25-30 similar issues with no resolution by Hyundai. This is a safety issue that will eventually cause an accident and needs to be resolved. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I own a 2023 Hyundai Santa Fe Calligraphy AWD equipped with the 2.5L turbo engine and 8-speed wet dual-clutch transmission. At approximately 39,900 miles, the check-engine light illuminated. Hyundai Bluelink diagnostics reported powertrain/TCU diagnostic trouble code P1C2D03, identified as a high-pressure electric oil pump motor position sensor fault. I am concerned because this same diagnostic trouble code and high-pressure electric oil pump/transmission issue was associated with Hyundai Safety Recall 236 (NHTSA Recall 22V746) involving certain earlier Santa Fe model years. Hyundai's recall documentation described the possibility of the transmission high-pressure electric oil pump malfunctioning and causing loss of motive power while driving. My vehicle is a 2023 model and therefore was not included in that earlier recall, but Hyundai has subsequently issued technical service information covering 2021–2023 Santa Fe vehicles equipped with the 2.5T engine and 8-speed wet DCT, including vehicles displaying DTC P1C2D03. The current Hyundai service procedure indicates that affected vehicles may require transmission replacement. I have stopped driving the vehicle because of my concern about a possible loss of propulsion and have scheduled an appointment with a Hyundai dealership for diagnosis. At this time, I have not experienced a loss of motive power or an accident. I am reporting the issue because a 2023 vehicle outside the original recall population is displaying the same fault code associated with the previously recalled transmission condition. I believe NHTSA should evaluate whether the affected population should include additional model years.

Collision warning sensor alarm randomly comes on my dash and my car slams on the breaks. Very dangerous, I’m scared to drive down the highway going 60mph. 80,109 miles 2023 Hyundai Santa Fe. I have not brought it in to a Hyundai dealership because they want a diagnosis fee and everything else. Hyundai should fix it. This alarm has happened several times than it will go away and come on like 3 times in a row, usually daily when I use the car

Horn stopped working

Subject: Formal Dispute: Warranty Breach and Failure to Repair – 2023 Hyundai Santa Fe Timeline & Facts:11/2/25 (~52,000 miles): I officially reported an intermittent loss of power and severe engine revving (up to 7,000 RPM). This created a severe safety hazard when merging and accelerating from an idle stop.3/28/26 (Under 60k miles): After months of diagnostic delays, Hyundai confirmed the Dual-Clutch Transmission (DCT) needed replacement under the 60,000-mile warranty. A Hyundai Case Manager tracked the issue.Service Delay: Hyundai delayed repairs due to a lack of loaner vehicles, which were grounded for recall updates. Commuting pushed my mileage to 60,218. The Case Manager assured me coverage was locked in because the defect was documented before 60,000 miles.4/8/26: Due to corporate protocol, they ordered a valve body installation instead of a new transmission.8/11/26: The valve body failed. Hyundai delaership resubmitted the transmission replacement request. Corporate denied 100% coverage because the odometer was now over 60,000 miles (60,218). They are offering only 80%, leaving me with a $1,000 plus out-of-pocket expense.Legal & Contractual Position:Hyundai is contractually and legally obligated to cover 100% of this replacement. Under federal and state consumer protection laws, any defect reported prior to warranty expiration must be fully repaired by the manufacturer, even if the final repair occurs after the mileage threshold. The current mileage is a direct result of Hyundai’s internal diagnostic and loaner delays.Demanded Resolution:I demand that Hyundai cover 100% of the transmission replacement costs immediately. I am hoping this escalation to the NHTSA will help in bringing this matter to a positive end result, otherwise I have no choice but to pursue formal legal remedies.

This complaint concerns a serious, unresolved powertrain/propulsion safety defect in my 2023 Hyundai Santa Fe. While traveling approximately 70 mph, the vehicle suddenly lost propulsion and would not accelerate normally while surrounded by highway traffic.MOST IMPORTANTLY, THERE WAS NO WARNING OR ADVANCE INDICATION. No warning lights, messages, or symptoms appeared before the loss of propulsion. I had no opportunity to anticipate the failure or prepare to safely exit traffic. This placed me and other motorists at immediate risk of a serious or potentially fatal collision.A Hyundai dealership inspected the vehicle and documented DTC P284001, Shift Fork D Position Fault. Despite this documented fault, the underlying safety issue remains unresolved. Hyundai has not identified a permanent correction or established that the vehicle is safe to operate.There has not been another incident because I will not risk another sudden loss of propulsion by driving the vehicle. The absence of another failure does NOT mean the problem is resolved. The vehicle remains available for inspection.I have repeatedly sought assistance from Hyundai and the dealership without a meaningful resolution. Newer information regarding a possible computer reset/relearn procedure has also been presented, but the dealership refuses to perform it.I reviewed NHTSA complaints for 2023 Santa Fe vehicles and found multiple reports describing similar safety symptoms, including sudden loss of propulsion, inability to accelerate, abnormal transmission shifting, and loss of speed. This raises serious concern that this may not be an isolated failure.A vehicle that can unexpectedly lose propulsion at highway speed WITHOUT ANY WARNING creates an extreme crash risk. I respectfully request that NHTSA review the similar complaints, investigate whether a broader transmission/powertrain safety defect exists, and determine whether corrective action is necessary before this results in serious injury or death.

I was driving, and the SUV all of a sudden lost power. I was trying to press harder on the gas pedal to keep up with the traffic, but the SUV was stalling. The SUV would not move, and as I kept trying to press on the gas pedal, a roaring noise like something was trying to turn but the engine kept trying to move the car. It felt like something in the car was trying to move but something kept slipping. I had to turn the car off in the middle of the street and restart it before it would move. Cars were blowing their horns. This is a safety issue and a dangerous Problem. The SUV just did the same thing a few days ago. I am calling the dealer to see what is wrong. I brought this car new 2023. It is under 12,000 miles

The horn stopped working.

COMPONENT/SYSTEM: The powertrain launch control system — the Transmission Control Unit (TCU) and 8-speed wet dual-clutch transmission paired with the 2.5T engine — fails to deliver engine power in response to full accelerator input from a stop. The engine does not rev and the vehicle does not move for approximately 1–2 seconds despite the accelerator pedal being fully depressed, then power engages abruptly and violently. The vehicle is available for inspection upon request. SAFETY RISK: The failure occurs when launching from a stop into intersections and cross-traffic. In the most recent incident, I was turning left across the roadway from a stop with an oncoming vehicle approaching. I applied full accelerator and the vehicle did not respond at all for approximately 2 seconds — no engine response, no movement — leaving me stationary in the oncoming vehicle’s path. Power then engaged violently and without warning, causing the vehicle to lurch across the road. I was nearly struck. Similar events have occurred multiple times throughout my ownership; this was the closest to a collision. DEALER CONFIRMATION: Not yet inspected by a dealer. A dealer service appointment is being scheduled. OTHER INSPECTIONS: The vehicle has not been inspected by the manufacturer, police, or insurance representatives. WARNING LAMPS/PRIOR SYMPTOMS: No warning lamps or messages have appeared before, during, or after any of the events. The failure is intermittent and occurs without warning. The condition has been present since I purchased the vehicle in October 2022 and has occurred regularly throughout ownership — numerous occurrences over more than three years. No warning lamps have ever accompanied it. ADDITIONAL: Condition persists with Idle Stop & Go disabled, ruling out engine-restart delay. Same 8-speed wet DCT was subject to Recall 236 (NHTSA 22V-746) on 2021–2022 models for similar throttle non-response; 2023 excluded despite identical hardware.

My dealership has reground the rotors on my car twice. Now with less than 40,000 mileson the car the brakes need ground again. The issue with the brakes is it causes the front end of the car to shake when the brakes are applied. This could lead to loss of control on down hill stops in slippery conditions.

First Failure occurred 7 months after purchase at 5,270 miles on August 1, 2024. The vehicle suddenly went into "Limp Mode" abruptly decelerating to 25 mph with a non-responsive gas pedal. A code reader displayed PO653 Sensor Reference: "Voltage B Circuit High". Dealer found corroded wire to battery and cleaned it. Second Failure: Horn loss to 1 tone. Fixed at 30K mile dealer service on June 12, 2026 and found to have faulty packing resulting in corrosion. At the same standard service the Brake System was flushed. 3rd Failure was 5 days and 437 miles (30,712 miles) after the 30K dealer service. On June 17, 2026 during my early morning commute while merging onto the interstate, alarms began to blare and the gas pedal suddenly became unresponsive. The initial alarms read Blind Spot Failure. Car would not accelerate from 40 mph that it was going coming down the bridge ramp so I took the very close off ramp down from the aqua duct and the console display alert showed "Engine Management System: details: Braking and Body Control System with a recommendation to get "a full system check...TODAY". I brought it to the dealer that afternoon and as of yesterday, 6/26/26 they can find nothing wrong, declaring it an intermittent issue and asked me to come get the car, refusing to continue looking or providing alternate options other than referring me to Hyundai Consumer Affairs.

Vehicle stalled while driving — unsafe loss of power. While driving at normal speed, the vehicle suddenly shut off without warning and the electrical system malfunctioned. I had to pull over and restart car. This created a dangerous situation and could have caused a collision. Prior to this incidenct, the vehicle had intermittent electrical issues during startup (flickering electronics). This is the first time the car has experienced during driving, and is now at the Hyundai dealership. The car has been reported as unsafe to drive. This appears similar to other Hyundai stalling/power loss issues and may indicate a developing safety defect. Requesting investigation.

We were at full stop with Auto Hold feature enabled. Car lurched / jumped forward with no depression of the gas pedal. This caused us to strike the car in front of us.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while driving and decelerating to approximately 10 MPH onto an exit ramp, the vehicle suddenly stalled and failed to restart. The contact noticed that there was blue smoke coming from the exhaust pipes, and several unknown warning lights and messages illuminated, including the Check Engine warning light. The vehicle was towed to the local dealer, who diagnosed that a fuel injector had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was not yet contacted. The failure mileage was 35,652.

I was driving down the road and came to a stop at a stop light. After accelerating again my car lost the ability to increase speed above 20 miles/hour and would not shift gears. I was heading to the turn lane to get on the interstate and quickly had to change lanes to find an area to pull over as I could not reach highway speeds. I turned the car off. I turned the car back on and the problem resolved. This is the second time this has happened. I have seen this problem mentioned dozens of time on Reddit message boards including Hyundai buybacks on some of these vehicles. It doesn't sound like Hyundai has any idea what is causing this issue. This issue should be looked into further.

Hyundai Corporate is refusing to ground or provide alternative transportation for a documented, warranty-covered engine cooling fault (Code P2181), creating a highway stalling risk. Hyundai's legal compliance team reviews these logs daily.

While running errands around town, I noticed my 2023 Sante Fe 2.5T was sluggish shifting out of first gear into second. The RPMS revved to about 3K before the transmission shifted into 2nd. I didn't notice any problem shifting into 3rd and above. I drove to a gas station for fuel and shut off my car. When I started it and began to drive, I received an immediate warning to take the car to a dealer and the check engine light came on. The car had the same problem getting out of 1st gear at each of the traffic signals I got caught at on my way to the dealership about 2 miles away. The following day, the service department contacted me and determined I needed a new transmission due to the failure of the Dual Clutch electric high pressure oil pump in the transmission. They submitted a parts request and Hyundai approved a refurbished DCT warranty replacement. The transmission only has 50200 miles on it I am second owner but the car was a CPO so I have full warranty coverage. I was given a loaner under Hyundai' warranty provisions. My main concern is that although this vehicle is a 2023 Sante Fe, it was put in service around August of 2022 and would therefore have the same transmission as the 2021 and 2022s covered under Hyundai recall 236, but this has yet to be acknowledged as far as I know. Please investigate my situation and consider further requirements of Hyundai! Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle activates the emergency braking system while driving. It has happened several times now, almost causing a collision. I took it to the dealership, they held it for a week and gave it back to me telling me they could not find anything wrong with it. They did not fix anything at all. It has since done it once more.

Shifter malfunction has appeared since I bought the vehicle new. Once I took it in, they said it was the software. The vehicle now skipped and hesitate in the lower gears. When in high gears ride fine. But once it stops and start driving again, lower gears won’t drive properly. Drives with hesitation and skips.

Two unsafe scenarios in past two months: 1) Driving 80 mph, engine misfire, vehicle will not accelerate past 1 rpm, had to drive home from out of town with very slow acceleration, dangerous to not be able to accelerate efficiently on highways 2) Driving 55 mph, all driver safety systems malfunction, accelaration completely disabled, had to coast to safe stopping point. Restarted vehicle and could drive home with check engine light on, incredibly dangerous for car to lose all ability to accelerate in the middle of a highway.

While driving on the interstate, while using cruise control, my vehicle braked and decelerated, uncontrollably. The collision alert alarm went off. I forced the vehicle to accelerate and it stopped the braking and the collision alarm ceased. I took the car to the dealer and they spend the day checking it over. They said they couldn’t get the same reaction I reported, but reset the cruise control. On my way back home on, again on the interstate, and with the cruise control activated, it again had the same failures. I called the dealer and told them. They asked if I had recently mounted any new equipment on the windshield. I said I had Velcro attached and EZPASS toll reader. They asked me to remove it, because might be interfering with the cruise sensor. After I removed it, and while continuing on the interstate, with cruise activated, it again repeated the same failures. The dealer arranged to have my vehicle towed to their shop.

It is not just this vehicle; it is ALL vehicles with adaptive cruise control and automatic emergency braking. When sensors get snow or debris on them, they shut the vehicles down without warning. I have had 3 times this winter when the roads were fine, cruise control set, and because another vehicle was kicking up road salt, the vehicle instantly shut off the cruise control without any warning to the driver, all 3 times I had traffic behind me at 55mph or on the highway at 70mph. The emergency braking is another issue, as it will bring the vehicle to almost a stop, and does not take into account if there are other vehicles behind it or not! How more people have not been killed because of these 2 systems is beyond me! BOTH of these systems and the vehicle they are on NEED to be recalled and either sensors removed or workarounds implemented, that at least give the driver some advanced notice before the cruise control is turned off or before a vehicle decides to hard-brake itself!

The front rotors need machining every 10,000 to 15,000 miles. The rotors experience exceeding distortion due heating by the brake pads. When brakes are applied, there are large vibrations in the front suspension which inhibits braking. This is especially true when braking on wet pavement where stopping distances become unsafe.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while operating the vehicle, the horn was inoperable and inaudible when pressed. The cause of the failure was not yet determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was approximately 31,000.

Today, i received an extended warranty for my horn. There is a known issue with water getting into the horn and causing them to fail. Upon researching this, people have reported having their horns changed several times. This is a safety matter that an extended warranty is not fixing. Please enforce a recall so that this matter may be properly resolved. Canada has already issued a recall, I hope we can do the same. Thank you.

Driving on sunny day, the fixed roof glass located between the windshield and sunroof exploded across the entire width of the glass insert with a very distracting noise.

On March 4, 2026, at approximately 7:30 AM EST, while driving my 2023 Hyundai Santa Fe Limited on [XXX] , the vehicle experienced a sudden loss of propulsion while traveling at approximately 70 mph (posted speed limit). The vehicle would not accelerate or maintain speed and would not move forward when placed in drive, indicating a failure within the powertrain/transmission system. The vehicle is currently located at a Hyundai dealership and is available for inspection upon request. This incident created a significant safety risk, as I was traveling at highway speed in active traffic when the vehicle unexpectedly lost the ability to move under its own power. This placed me at risk of being rear-ended and made it difficult to safely maneuver out of traffic. The vehicle was inspected by a Hyundai dealership. Diagnostic trouble code P284001 (Shift Fork “D” Position) was identified, and I was informed the failure is transmission-related. The condition was reproduced by placing the vehicle in drive, at which point the vehicle would not move. The vehicle has been inspected by the dealership. The manufacturer has been notified but has not physically inspected the vehicle. No police or insurance inspection was involved. There were no warning lights, messages, or prior symptoms before the failure. The issue occurred suddenly without any indication of a problem.

Oil pan leak.

I have been fighting this issue now for 2 years, vibration while driving interstate speeds, especially right rear seat. I have had tires replaced twice trying to fix balance issue only to find out that one rim will not road force balance correctly, even with tire matched it only reduced road force balance to 20lbs (30lbs with out match). I have had it at discount tire and Gettel Hyundai of Lakewood ranch, FL several times. Hyundai sent a senior tech to look at tires, did not speak to me to get explanation of my concern, did a balance, got same numbers and said was good to go. My other 3 rims have a max road force of 12lbs without even being matched. This causes vibrations when driving, extra wear and force on the tire and is a safety concern. This rim is the issue and Hyundai refuses to fix it.

Driving to work and a loud noise (pop) was heard and then I realized the sunroof had basically exploded. Glass was all over the car and all over myself. I immediately got off the road and turned on my hazard lights to assess the situation. This could have caused an accident had I not remained calm. Contacted dealership this morning. Waiting to hear back. No prior warning to this happening.

While driving on the interstate at 70mph the vehicle’s fuel injectors failed causing the vehicle to lose power suddenly.

On 6/7/2023 with the original owner, the vehicle displayed code P1c2D03, according to carfax history the transmission was replaced 7/12/2023. I purchased the vehicle in May, 2025. In December, 2025, while driving to work I experienced intermittent loss of ability to accelerate, followed by the vehicle again displaying code P1C2D03 in the Bluelink app. The dealership performed a software update and told me to come get my car. On Monday, February 16, 2026, I started the vehicle and the dash displayed "Transmission error. Check transmission fluid immediately!", I again had it towed to the dealership where it has remained for the past three weeks. Now I have been called again to pick up the vehicle as the dealership cannot duplicate the error. At this time I am unsure if the service center actually checked the transmission fluid as the warning indicated should be done.

I am submitting this complaint regarding a safety-related incident involving my 2023 Hyundai Santa Fe on February 14, 2026. While driving, the vehicle suddenly began to overheat, creating an immediate safety hazard. I was close to my home and was able to return there safely, but once parked, I observed coolant leaking from the front of the vehicle. Due to the risk of further overheating or engine failure, the vehicle was not drivable and had to be towed to a local Hyundai dealership. At the time of the incident, the vehicle had fewer than 38,000 miles and was purchased brand new. Despite this, the dealership informed me that the repair would not be covered under warranty, claiming the radiator damage was caused by “road debris.” However, they did not provide any evidence of an impact, puncture, or external damage. The only documentation offered was a video showing coolant spewing from the radiator after a technician inserted an object into the grille. This video does not demonstrate any pre‑existing road damage or confirm that debris caused the failure. I requested proof of actual damage multiple times, including photographs or inspection notes showing an impact point, but none was provided. Without verifiable evidence of external damage, I am concerned that this may represent a premature component failure or a potential safety defect in the cooling system. The sudden overheating while driving, combined with the lack of substantiated cause, raises significant safety concerns for me and potentially for other owners of this model. Thank you for your attention to this matter.

I have attached a photo since I couldn’t save it

The horn stops working which is a safety hazard in case someone is backing into you, etc. This horn has stop working 4 times and had to be replaced.

1. The factory-supplied scissor-type jack that came with my 2023 Hyundai Santa Fe failed. While changing a flat tire on the side of the road, the jack collapsed three times and could not hold the vehicle. Yes, the jack is still available for inspection. I have it in my possession and have provided photographs of the jack, its capacity label, and the incident location as evidence. 2. My safety was put at serious risk. The vehicle fell off the jack three times while I was attempting to change the tire on the road. The car remained on the ground without a tire until roadside assistance arrived. If I or a family member had been under or near the vehicle when it fell, we could have been seriously injured or killed. My wife and three toddlers travel in this vehicle, making this a major safety concern for our family. 3. No. Rosen Hyundai dismissed my concern. Service Manager Jeff Bravieri claimed the jack is rated for 3 tons (6,000 lbs) and blamed user error. But my photo shows the jack's label states 1,200 kg (2,645 lbs). The road was flat. The dealership dismissed my safety concern and refused to replace the jack unless I paid for it. They have not inspected the jack despite my request until the involvement of Hyundai Motor America. 4. Not sure, that vehicle and jack have been inspected by the manufacturer, police, or insurance representatives. However, manager later agreed to inspect it and instead blamed user error. I am reporting this directly to NHTSA because the dealership and Hyundai have not taken this safety defect seriously. 5. No. No warning lights or signs. The jack looked normal. It failed the first time when I used it in an emergency situation. 6. The jack label says 1,200 kg (2,645 lbs). My vehicle weight is 1,724 kg (3,801 lbs) . The jack is under-rated and unsafe. It failed on a flat road. The dealer ignored the evidence. I fear this could happen to others and cause serious injury or death.

Needed to use horn in an emergency situation and that's when I found out my horn no longer works. 20,000 miles on 2023 Hyundai Santa Fe.
