What 108 owners told NHTSA about the 2018 Hyundai Santa Fe Hybrid Hev

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.

In September 2024, my 2018 Hyundai Santa Fe experienced an unexpected engine lock-up while driving, creating an immediate safety hazard. Vehicle lost power, began smoking, and posed a potential fire risk. Fire department responded to prevent the engine from catching fire and had to spray the engine compartment with high-pressure water. Following this incident, vehicle remained in Hyundai’s possession for ~9 months for engine-related repairs. When we picked up the vehicle after the prolonged repair period, front-facing camera had completely stopped functioning. This camera has always worked prior to the engine lock-up and was functioning the day of the incident. This was reported to the dealership, Hyundai Motor America. A case manager (Nemesh) took the case. Very supportive, helpful and provided a thorough process for investigating the situation. However, all the sudden case was assigned a new case manager (Bryan) and the process immediately changed and the claim was denied. Given the timing and circumstances, the camera failure appears to be the result of electrical or component damage caused during the engine failure/fire-prevention event. The dealership also confirmed that no independent inspector ever assessed the vehicle for secondary damage despite my repeated requests. Hyundai later denied responsibility without conducting any physical inspection of the damage. This sequence of events — sudden engine failure, required fire-response intervention, prolonged repair, and subsequent electrical component failure — raises significant concerns about safety and the potential for related electrical or wiring issues caused by the engine incident. I am reporting this because the underlying engine failure and fire-risk conditions represent a serious safety defect, and related component failures may indicate broader issues with damage resulting from these events. Also Hyundai not letting the independent inspector assess gives me great concern something was missed.

I was at the Tim Hortons drive-thru stopped behind a car in front of me the car in front of me started to go to the order window , as I let off the brake to start to go my suv took off full speed! I hit the brakes as hard as I could and the car kept moving forward like the throttle was stuck at full acceleration. I wasn't even hitting the gas pedal, after my vehicle struck the car and continued to smash into the car while I was holding a brake I put it in neutral and then the car finally came to a stop. I had 5 children in the car. And I am seeing this being an issue in alot of hyandai vehicles. And alot of complaint with this same issue. If this would have happened on the hiway it could have possibly killed or Injured someone. I am scared to death to drive the vehicle again.
