Car accelerated by itself in drive. I'd to either apply brake or put the car in neutral to stop it. When shifted back to d, it auto accelerated. After I got home, shut it off and after 10 min. It started working normally.
Uncommanded acceleration. The car accelerated to above highway speed, and required continual breaking to maintain control. When home and in park, engine continued to rev to max. Shut car down, and when restarted it returned to normal operation. No obstruction of gas pedal.
The car was in acceleration mode at every speed on the highway, residential streets, at stop signs, always exceeding the speed limits. I continually braked to maintain control. Tires squealed when I released the brake at stop signs. There was nothing under the gas pedal. I didn't dare drive into the garage; the car would have been in the kitchen. When I put it in park, engine still revved.
