What 131 owners told NHTSA about the 2024 Hyundai Santa Fe Hybrid Hev

I was merging onto the highway and the acceleration stopped working and the vehicle would not go more than 25 mph. Had to restart car in shoulder, isue seemed to self correct but then it happened 10 minutes later stranding me in between the highway and exit ramp. This was a huge safety issue and myself and others lives were at risk. I am bringing the vehicle in for inspection but this seems to be a recurring hyundai issue. There were no warnings that came on. The auto mode on the dash went from green to an amber color. When i restarted the vehicle nothing changed. After the second time it occurred a check engine light came on.

We just brought this vehicle in for the ongoing transmission problem (previously reported to your agency after the car self-accelerated), as well as the missed seatbelt recall that was not addressed at the last dealership. I advised the service advisor that the seatbelt recall needed to be fixed. The service advisor contacted us several hours later to tell us that they were replacing the transmission. 10 days later we picked up the vehicle after the transmission replacement, and the service advisor told us they did not do the seatbelt repair, citing lack of parts and/or special order. I asked if this was a safety issue and if I should leave the vehicle with them for longer, but was told not to worry about it, and to bring the vehicle back at another time. Fast forward to today, and the vehicle is rolling forward when we start it. This is worse than the way it rolled forward before the transmission replacement. Coupled with the disregard for the seatbelt recall, I believe there is a serious safety issue with this vehicle. I have notified Hyundai Corporate, as well as our attorney, and will be contacting the dealership to drop the vehicle off. I have a video recording of the car rolling forward during startup, but it appears I cannot upload it here. I have forward that video to the above mentioned entities, and am happy to share it with your agency as well.

I have had my vehicle inspected twice for an intermittent issue with the rear driver's-side brake light. The brake light continues to go in and out even though the issue has not been identified during inspection. Multiple people have informed me that the brake light was not working, but when checked later, it was functioning again. Because the problem is intermittent, I am concerned that it has not been properly diagnosed. In addition, I have experienced ongoing transmission and drivability concerns. While stopped at traffic lights, the vehicle has occasionally accelerated unexpectedly or surged, and it can be difficult to shift into gear to proceed. I have also experienced hard shifting when moving from Park or Reverse into Drive. These symptoms continue to occur despite being told that no problems were found during inspection. I am requesting a more thorough diagnosis of both the brake light issue and the transmission/drivability concerns, as these problems are ongoing and may present a safety risk.

The contact owns a 2024 Hyundai Santa Fe. The contact stated that the anchor in the third row detached. The vehicle rolled while in the drive position. The vehicle failed to accelerate. While reversing, the vehicle jerked. No warning lights The vehicle was taken to the local dealer on five occasions and was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 20,000. The VIN was not available.

My 2024 Hyundai Santa Fe (VIN: [XXX] ) was manufactured on March 14, 2024, in [XXX] . The vehicle is currently experiencing dual-clutch transmission (8DCT) juddering, shuddering, and extreme hesitation when trying to accelerate from a complete stop at traffic lights and intersections. This creates a severe lag in acceleration, leaving the vehicle dangerously exposed to oncoming traffic. This component failure directly mirrors the mechanical hazards outlined in NHTSA Safety Recall 263. Because my manufacturing date falls just outside the official recall window, this vehicle has not received a formal recall remedy, yet it actively exhibits the identical, dangerous powertrain defects, suggesting the recall's production scope may be too narrow. Furthermore, in November 2024, the vehicle suffered a catastrophic safety failure where it completely lost all propulsion power for approximately 30 seconds while moving through the middle of a live intersection. Most recently, on XXX, right after being released from an extended 38-day service stay at an authorized dealership, the electronic infotainment displayed an active warning screen stating the car should be shifted to park while the vehicle shifter was physically and securely locked in Park. Time-stamped video evidence of this active transmission/braking sensor failure has been captured and preserved. The vehicle remains an active, uncorrected threat to my physical safety on the road.

We have had several transmission issues with this vehicle for over a year. On March 5th we dropped the car off for an oil leak, a malfunctioning middle row seat belt, and an on going transmission clunk and roll. The dealer repaired the oil leak, replaced the seat belt, (damaged the interior of the vehicle while doing so, then denied it) and said they were unable to replicate the transmission problem. The car went back to the dealer again on March 26 for the transmission clunk and roll. They kept it for 8 weeks, and said they couldn’t replicate the issue. I have confirmation that they didn’t even start the vehicle for 4 weeks. We picked up the Vehicle on May 22, and the issue persists. Yesterday, when pulling out of a gas station, the vehicle accelerated on its own until I intervened stepping on the brake pedal. When I typed in the issue to Google, I was made aware that the vehicle now has a front seat belt safety recall from April 6, which the dealer didn’t even advise us on or offer to repair. I am finding out about this on an interstate family drive and we are of course terrified of driving our vehicle now, based on the unintended accessories and now faulty front seat seat belts. I have asked Hyundai serval times for a buy back which they have refused. Corporate has asked us to bring the car back to the dealer this week, and we are about to sign papers with a lemon law lawyer tomorrow. I wanted to at least file this complaint so that it is in writing should something happen to us in our travels this week. This has all been so unacceptable with Hyundai. We bought this car new and it is paid off.

The vehicle has experienced repeated transmission-related failures beginning at approximately 5,000 miles. The dashboard warning “Transmission System Error – Check Transmission Oil Immediately” first appeared while driving and was accompanied by sudden loss of power. When this occurs, the vehicle loses acceleration and drivability while in motion, creating a safety risk in traffic. The only way to temporarily clear the warning is to pull over, shut the vehicle off, and restart it. Photographs of the warning message were documented at approximately 6,738 miles on [XXX] and again at approximately 12,664 miles on [XXX]. The vehicle was returned to the selling dealer in Massachusetts multiple times for the same issue. During the first visit, the dealer drove the vehicle approximately 19 miles but stated they could not duplicate the problem. During the second visit on or about 3/25/2025, the dealer kept the vehicle for approximately six days while providing a loaner vehicle, but again stated they could not duplicate the condition. The vehicle was later inspected by another Hyundai dealer in New Hampshire on 8/19/2025 for the same dashboard warning and loss of power condition while driving. That dealer found the transmission fluid level below specification but stated they could not duplicate the warning message during inspection. Following that visit, the transmission warning did not reappear until [XXX], when the same “Transmission System Error – Check Transmission Oil Immediately” warning returned again while driving. On [XXX], the situation escalated into a possible rollaway event. While at an auto detailing facility, the vehicle was reportedly placed in Park with the engine running after being repositioned. The operator stated the vehicle indicated it was in Park. Moments later, after the operator exited the vehicle, the vehicle moved from its parked position and rolled into a building. The event was documented in writing by the detailing facility. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

3 times now, I am driving and the vehicle goes into limp mode, the "D" on the dash is flashing but the vehicle sends no codes. The tech said the vehicle can immediately delete the code and they can't fix it if they can't duplicate it. It also hesitates when accelerating and is dangerous to myself, my 4 children and anyone driving around me when it goes into limp mode. There is no code, therefore they say they can't do anything about it.

2024 Hyundai Santa Fe purchased new in May 2024. On three occasions since December 2025, while driving, the dashboard went completely black as if the vehicle shut off. The Hyundai startup logo then reappeared while the vehicle was still moving, and the vehicle lost acceleration. The most recent event occurred at highway speed, approximately 65-70 mph, requiring us to coast to the shoulder. No warning lights appeared before the event. A video of the most recent incident is available. Dealer inspected vehicle but could not duplicate the problem and reported no error codes.

NHTSA ODI 11725263

When making a right turn from a complete stop, the vehicle intermittently exhibits noticeable hesitation and reduced acceleration compared to normal straight-line launches. This has occurred approximately 5–6 times. The delay in power delivery creates an unsafe condition when merging from on-ramps into higher-speed traffic, as the vehicle does not accelerate as expected. This mismatch between expected and actual acceleration can lead to misjudgment of traffic gaps. No warning lights or diagnostic messages have appeared. The issue appears intermittently and specifically during right-turn launches from a stop.

On November 18, 2025, at 24,370 miles, the vehicle suffered a catastrophic powertrain failure, triggering a dashboard warning: "Transmission system error! Check transmission oil immediately." The vehicle suffered a loss of reliable motive power. This sudden failure is a severe safety hazard that presents a high risk of stalling or stranding in active traffic, which is especially dangerous as this vehicle is used for a 40-mile round-trip school commute four days a week on local highways. The dealership replaced the transmission, keeping the vehicle out of service for 27 days. However, the exact same critical failure occurred a second time on December 24, 2025, at 24,878 miles. The vehicle was once again completely incapacitated and required a second transmission replacement as well as a new TCU, resulting in an additional 50 days out of service. Two catastrophic transmission failures within a 500-mile span on a brand new vehicle demonstrate a highly dangerous defect that puts the driver, passengers, and other motorists at unreasonable risk of a crash due to sudden loss of power.

While driving my 2024 Hyundai Santa Fe, the vehicle experienced a complete dashboard and system blackout, as if the vehicle shut off and rebooted. This has occurred on two separate occasions. On one occasion, while stopped at a traffic light, the dashboard went completely black and restarted. After the system rebooted, the vehicle would not accelerate or move when the accelerator was pressed. I had to turn the vehicle off, restart it, and wait before it would drive again. The suspected malfunction involves the vehicle’s electrical/infotainment and related vehicle control systems. The vehicle is available for inspection upon request. My safety and the safety of others were put at risk because the vehicle lost critical dashboard information and temporarily lost the ability to accelerate while in traffic, creating the risk of being struck by other vehicles. The vehicle was inspected by an authorized Hyundai dealership (World Hyundai of Matteson). On December 23, 2025, I was informed by the dealer that a system/infotainment “glitch” had been identified and that a replacement part would be ordered. However, the part was never replaced. The dealer later stated that because the issue could not be duplicated during test drives (approximately 85 miles driven), the repair was not authorized. The dealer acknowledged the issue could not be reproduced on demand. The manufacturer (Hyundai) has not yet physically inspected the vehicle beyond dealership involvement. No police or insurance inspections occurred, as there was no crash. There were no warning lamps or messages prior to the failure. The failure occurred suddenly with a complete dashboard blackout and system restart. The first occurrence happened prior to December 23, 2025; the second occurred afterward. The issue is intermittent and unresolved. I am concerned that the defect must reoccur while driving in order to be repaired, posing an ongoing safety risk.

I was driving and the car started to loose power and then the engine light came on and the car would not go. Everything happened at one time. The wrecker took the car to the dealer and the dealer confirmed the transmission went out. It is very dangerous for a new car to have the transmission fail while driving. This is a new car. The transmission failed and it is available for inspection at the dealer. The car is currently at the dealer and I am waiting to find out how long it will take to get a new power train.

this truck has repeatedly gone in for service over 6 times for multiple issues. The worst issue which they cannot fix is the vehicle going into limp mode while driving . Loosing all acceleration then racing on its own . This is a very dangerous problem when on the highway.hyundai service keeps telling me that the diagnostic is not showing a problem. This can be caused due to many things including transmission electrical or computer problems. I have reported to the office of consumer affairs and they claim hyundai dealership in myrtle beach has not responded to them. meanwhile i am driving in a very scary situation not knowing when this will occur. This happens at random times with no warning. This has happened at least 10 times in the last few months.

Transmission. Less than 6 months of buying the vehicle, Hyundai replaced the transmission and now I’m still having problems..it revved up to 2.3 rpms but didn’t change gears then jerks into gear..not everyday but atleast once a week. I’m waiting now on the dealership to look at my car now..but they’re dragging their feet.

The transmission is the problem that caused the vehicle to downshift while driving and resulted is a sudden jerk and slowdown in speed. My safety was at risk as the car slowed down suddenly and almost caused the vehicle behind me to rear end my vehicle. But luckily the other driver was able to stop. I previously brought the vehicle to Hyundai service (12/12/24) and they indicated that they couldn’t replicate the problem and there was no situation. The vehicle will be brought to the aforementioned service center again to check the situation (1/07/25). There were no warning the first time it happened, as mentioned earlier and after the second incident the car displayed the message that occurred the first time again which I have attached.

On December4th 2024 my car rolled forward into a barrier post. I stopped to get air in my tires and the Parking Allert went off as I got near the barrier post. I then parked my car. I left my car running and driver door partially opened. I dropped the valve cap between the spokes of the last tire being filled. So, I got into the car and backed up about three feet to get the cap. Parked the car got out and it rolled forward into the barrier post. I was completely out of the car but just by my driver door. I tried to get back in but it was too quick. Subsequently, I drove to work to let my supervisor know i would need time to go to the dealership. I was concerned air bags would deploy since that didnt happen. Also because the car didnt stop on its own felt the integrity of systems were questionable. So, I repeated the steps at work like the incident. Except, I stayed in the car. The car beeped and the dash said Shift to P when my door was open and placing in drive and reverse. I NEVER got any indications of such when the car hit the barrier. I found the two DTC's that showed on my Hyundai App were related to DTC U110387 and U110382. I had 99 miles on the car having purchased it with 15 miles on it. The original date of these DTCs is Aug 27th, 2024, with a last reported Aug 30, 2024. I see recalls 24V529000 and 24V246000. I don't know if they are related. but this has to be addressed. My car is at the dealership being repaired and my insurance rate will no doubt go up and the value of my car down. This isnt right.

My vehicle was in for repairs at both a collision shop and a dealership following a minor accident. When I got the vehicle back, I found that the seat controls were not working, preventing me from moving the seat backward or forward. During a test drive, the car lost power despite the gas pedal being fully pressed; it wouldn't accelerate and then suddenly jerked forward. This could have caused an accident if I had been on a busy highway. Further testing revealed an abnormal noise at 1500 RPM in multiple gears. The vehicle has been towed back to the dealership, but there's no word yet on when it will be fixed. Hyundai has been contacted multiple times, as the car has been awaiting parts and undergoing repairs for over four months. They don't seem to be taking these safety issues seriously nor helpful in resolving the issue.

At approximately 1500 miles on the odometer, I started to receive a warning roughly one out of every 3 times I started my 2024 HYUNDAI SANTA FE. The warning would flash red and read "Transmission System Error!, Check transmission oil immediately" and would refuse to move out of first gear, revving to approximately 5000 RPMs. The onboard vehicle diagnostic system reads all systems NORMAL when performed and this error requires a vehicle restart to clear.
