Filed Aug 5, 2026 · Engine · MD

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

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.

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.

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.

On a clear road a sencor comes on detect comes on says detection collision. The breaks come on when you are traveling on interstate or two lane roads. When you are traveling 75 mph and breaks come on all of a sudden on the highway. We are lucky we never got hit in the back of the car going that fast. We will stop 75 to 35 mph in 10 seconds.

Was driving at 10 MPH on highway car began to cut out run rough and produce an extremely pungent smell of gasoline.. then stalled.. vehicle serviced and low pressure fuel injector had a leak causing fuel to spill onto the vehicles starter causing it to fail as well.. both were replaced under warranty by dealer. Highly concerned about fuel leaking from injector system onto a hot engine and electrical components and the aerosolized fuel. Police advised not to start vehicle due to fuel leaking and smell.

My 2023 Santa Fe Limited has 3,000 mils on it. At least four times it had low speed hesitation (lags then revs up for a few seconds). It’s a problem with the DCT (Dual Clutch Tranny) Hesitation pulling onto a highway poses a significant risk of a faster car colliding into my car. I called my car dealer and the service manager said they know they are having problems with this. He said they tried everything to remedy the problem but, there is no solution. They said the only way not to have the problem is to get a different car!!! Hyundai should have a recall on this hesitation matter before someone gets injured or killed. It’s a safety issue. The last time it happened will be the date of my incident report.
