Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I tried accelerating on the highway (pch in santa monica, ca) while traveling forward at about 45-50 MPH, but the vehicle hesitated. This is the forth time there has been a hesitation in acceleration since owning the car, but this time there was a message on my dash. The message stated that there was an obstruction with the pedal and acceleration was retarded. I later looked down at the pedals felt around the them, but found nothing obstructing. At the time, the vehicle had less than a quarter tank of gas but not low enough for the low fuel warning to come on. …”
