Brakes
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.
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.

We took our 2018 Santa Fe in for service because the check engine light came on and we lost power when accelerating. We were told that it has "catastrophic engine failure" and that we need a full engine replacement. On a less than 5 year old car. We are being blamed for this although we have kept up with regular oil changes and service. We were told that we could not get any warranty on the engine. We have been quoted $7,500 for an engine "replacement" and a 1 year warranty. They do not make the engine any longer so it is not even a true replacement. We brought it in to Hyundai of Metairie. They will not answer or return our calls. Do not buy a hyundai.
