Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was recently in an accident at a stoplight. When I arrived at the stoplight something fell out of passenger seat onto floor. I put the truck in park, took off my seatbelt, leaned over to pick up item and put it back on the seat. I then put seatbelt back on and put foot on brake and put the truck into drive. It all happened pretty quickly and can't swear to the specifics but I think the truck may have jumped a little when I put the truck into drive and propelled me into the car in front of me at a very low speed. …”

During that time the vehicle is not in gear and can roll in any direction. There is a software fix for this that I must pay the dealer to install. This happens every cold start.”
