As I slowly pulled into a parking spot, the car rapidly accelerated (as if I'd floored the accelerator - I didn't), jumping a curb. I slammed on the brakes trying to get it to stop. I ended up running into a parked car before I could get it to stop. I'm worried that it will do it again with someone in front of the car. There's nothing to inspect other than my broken fender from the collision. I don't know what component might have caused this. There were no warning lamps, messages, or other symptoms prior to this occurrence. The car is in good working order. Note: The claim form attached says "No driver", but that is incorrect. I was driving; there was no driver in the other vehicle (a parked car).
