Engine

54 reports3 fires
“While driving, the vehicle developed a strong odor of engine oil, followed within minutes by illumination of the red oil pressure warning light. Inspection determined that a bolt had exited the engine's timing assembly, broken the timing chain, and punctured the timing cover, discharging engine oil throughout the engine compartment while the vehicle was in operation. Engine oil was sprayed onto hot engine and exhaust components while the vehicle was being driven on public roads. This presents a fire hazard. The same failure also risks sudden loss of engine oil pressure and seizure without warning, which would cause an abrupt loss of motive power in traffic. Approximately twelve days before this failure, the check engine light illuminated. The vehicle was taken for service within two days. The technician was unable to clear the code or identify the cause and advised a dealer inspection. No warning of imminent catastrophic engine failure was provided by the vehicle. The vehicle was towed to a Hyundai dealership, which quoted $6,932.28 plus tax and characterized the work as a "timing repair." This vehicle is equipped with the 3.3L Lambda II GDI V6. I am aware that…”

Power train

10 reports1 crash
“On April 13, 2026, I arrived home and parked the vehicle, engaging the traditional shifter into the "Park" position and turning off the engine. After exiting and standing on the ground to retrieve a purse from the cabin, the vehicle spontaneously and rapidly began reversing. ​As the vehicle gained momentum, I was struck by the driver-side door, which knocked me down and resulted in the vehicle running over me. The vehicle only stopped its rearward movement once it collided with a neighbor's parked car. Only after the vehicle began moving did the horn begin blaring, indicating a delayed rollaway alert. ​This incident resulted in a fractured ankle that required surgical intervention. Despite the traditional shifter being placed in "Park" and the engine being off, the vehicle failed to remain stationary, representing a catastrophic failure of the parking pawl or transmission engagement.”

Steering

8 reports1 related recall
“At 118,000 miles Downhill brake, transmission and 4 wheel drive were damaged from the hyundai dealership not fullfilling warranty. They disconnected my tow hitch and my transmission was burning .. smelled like a bon fire. Took me 1 year to repair and have transmission changed through warranty but they didnt change the other components that were damaged due to negligence from the hyundai dealership. The dealership was very rude and didnt dedication their attention or care to truly finding what was wrong with my vehicle.”
