Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Sudden deceleration. Occurred at complete standstill, 25mph and 65mph, speed appears not to be a factor. Check engine light comes on and cruise control quits and cruise light blinks and engine defaults to 1500rpm, all happens simultaneously, ergo no warning. Complete loss of gas pedal control. Intermittent problem. Can happen a few times a day or nothing for a week. Tends to happen more from a cold engine start and within 3 miles of thee start. Very dangerous if on freeway, especially in fast lane and pulling out onto street, etc.”
