Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“There is a speed control issue. Intermittently, the car will become locked at 2 RPM while still accelerating to 65+ MPH. The driving is non-specific; I could be idling, on the freeway or on surface streets. Although I remove my foot from the accelerator, the car continues to speed up. Immediately turning off the engine does not eliminate the issue either. Once the car is turned on again, it locks at 4 RPM while in park. The issue may take up to 30mins to subside. Luckily, the brakes have yet to fail when the car voluntarily accelerates (although this does wear on the brakes like crazy).”
NHTSA complaint #10451503, filed 2012-03, 34,000 miles“Gas pedal sticks during acceleration; does not release even when applying brakes hard; have to shift to neutral, turn off ignition to stop vehicle. Tt”
