Example complaints

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

“My 2003 Mazda b3000 pickup spontaneously shifted from neutral into reverse and crashed the (driver's side) open door into the inside wall of my garage. The vehicle was idling and unoccupied, and the parking brake was not engaged. The force of the crash was enough to bend the door. I called the local police department, but was informed that they do not issue report numbers for minor losses incurred on private property. …”
