Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Gas pedal went all the way to the floor and would not release. I kept hitting the pedal to try and release it for about 2 miles. I kept my foot on the brake to try and slow the car down, but that didn't help. The floor mat was not under the pedal because it is too short to reach it. After hitting the pedal as hard as I could numerous times it released.”
