“The back hatch would not open while the car was on and in park. Upon reaching in without being in the car, we turned it off, and it engaged reverse on its own, causing it to reverse immediately almost causing terminal harm to myself and my family. It careened into the woods with us unable to stop it due to the immediate speed. No one was in the vehicle, it was solely self propelled. We have a video of the path it took and the damage it caused. When the car wrecked, even when turned off, the lights and windshields wipers engaged by themselves.”Owner report · Electrical System · Apr 2026
