2025 Hyundai Santa Fe

While operating the vehicle, the vehicle suddenly began severely hesitating and stalling. During the incident, engine RPM surged to approximately 6,000 RPM and accelerator pedal response became abnormal. The vehicle was not responding normally to accelerator input, which significantly affected the ability to operate the vehicle safely. The vehicle subsequently recorded diagnostic trouble code P0304 – Cylinder 4 Misfire Detected. The abnormal operation of the vehicle during the incident was also captured on video. The vehicle was taken to an authorized Hyundai dealership for diagnosis. The dealership has advised that because the condition is not currently occurring and they have been unable to duplicate the problem, they may be unable to diagnose or repair the vehicle. The safety concern is not simply an illuminated check-engine light or a stored P0304 code. The concern is the combination of severe hesitation/stalling, abnormal accelerator response, and the engine surging to approximately 6,000 RPM while the vehicle was being driven. The cause of the condition has not been identified and, at the time of this complaint, the vehicle has not been repaired for the underlying problem. I am concerned that this condition could recur without warning while accelerating, entering or crossing traffic, or traveling at highway speeds. A recurrence could result in an inability to accelerate normally, unexpected vehicle behavior, loss of normal vehicle operation, or a collision. Hyundai has been notified of the issue and I have requested further technical investigation of the engine misfire as well as the transmission/TCU and electronic throttle/accelerator systems due to the high-RPM event and abnormal accelerator response. I am submitting this complaint because this appears to be a potentially serious safety-related defect and I want NHTSA to have a record of the incident and determine whether similar stalling, high-RPM, acceleration, transmission, or engine-misfire.

The contact owns a 2025 Hyundai Santa Fe. The contact stated that while driving at slow speeds, the vehicle independently accelerated while the accelerator pedal was only lightly depressed. There were no warning lights illuminated. The vehicle was taken to a dealer, where the pedal sensor was adjusted. The vehicle was repaired; however, the failure recurred. The vehicle was taken back to the dealer; however, the failure could not be duplicated. The vehicle was not diagnosed or repaired. The contact stated that the vehicle was unsafe to drive. The manufacturer was made aware of the failure. The failure mileage was approximately 17,000.

I tried to drive my 2025 Hyundai Santa Fe Hybrid; the vehicle displayed a gear selection error message stating something like "gear already selected". The vehicle would not shift properly and would not power off or restart. I attempted multiple shutdown and restart attempts using the Start/Stop button with no success. The vehicle remained in this condition for about 30 minutes and would not allow normal operation or shutdown. Due to safety concerns, Hyundai roadside assistance was contacted and a tow truck was dispatched. Before the tow arrived, the vehicle spontaneously allowed shutdown without any intervention. This was a safety related failure involving the shift-by-wire system and vehicle power-down logic. The issue occurred without warning and left the vehicle inoperable. The vehicle had app 7150 miles at the time of the incident.

This car was in a BBB binding Arbitration and Hyundai was told to fix: speed control malfunction, speed linit not posting to hub arbitrary fan engagement. The Dealership ALM West had the car 2 weeks and the car sat on their lot. They said we are unable to duplicate the problem. Now in addition I showed them the cracked windshield and they were not responsible. I had an insurance complaint I took it to Safelite and replaced the windshield yesterday and I got it back with a new windshield and it also had a Crack in the replacement windshield. I think Hyundai knows there's a problem with the glass which is also part of the safety system of the car.

The forward attention warning (FAW) on the 2025 Hyundai Santa Fe calligraphy can not be deactivated. Correction, it can be turned off for normal driving. For instance, driving around the city or not using smart cruise control. As soon as you turn on the smart cruise control it's reactivated and can't be turned off. The FAW does not work when using prescription sunglasses / non prescription sunglasses or if the sun is hitting the inside of the cabin a certain way. The FAW constantly flashes warnings and beeps at you even though you are looking forward and keeping your eyes on the road. If you look far down the road you shift your eyes up some, and the system beeps and flashes warnings to keep your eyes on the road. On a recent 230 miles trip I did not wear my prescription sunglasses / non prescription sunglasses and the FAW system went off at least 50 plus times and I had my eyes on the road at all times. Very distracting, I then had to take my eyes off the road to see why it was beeping and telling me to keep my eyes on the road. The FAW system actually makes for a stressful and distracting drive. At this time the FAW is useless. I took the vehicle to the dealer and the FAW is not a system that can be turned off. Hyundai needs to allow the dealers to be able and deactivate the system.

Hyundai Distracted Driver feature is FAULTY and VERY hazardous! If someone puts on sunglasses to drive SAFELY, the vehicle says you ARE distracted; and cuts the cruise control and starts braking on its own. VERY BAD!!! The vehicle is almost undrivable. Many others are having their dealerships buy their Hyundai Santa Fes back because they are nearly undrivable and are a general US roadway hazard, due to the way the faulty "Distracted Driver" feature kills cruise control AND actually distracts drivers constantly ... causing very unsafe driving conditions. Might have to get our dealership to buy back our brand new 2025 Santa Fe Limited (as MANY others have already done). The Distracted Driver feature actually distracts drivers constantly AND causes unsafe and hazardous driving conditions. Please ... please ... please strongly compel Hyundai to fix this A.S.A.P., by Hyundai issuing a patch to their system update that allows drivers to turn off/disable the hazardous "Distracted Driver" feature.
