Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was stopped in front of my garage (waiting for the door to go up). When I lightly pressed on the gas pedal to pull in, the engine roared and the car suddenly leaped forward at a very high rate of speed, going thru my detached garage wall. The accelerator pedal stuck and I could not get the car to stop. I have pulled into this garage thousands of times and knew this was the car. Slamming on the brakes could not stop the car because it was accelerating too quickly. Hitting the brick facade of the condominium, beyond the detached garage was the only thing that stopped the car. …”
