Example complaints

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

“After a round trip 25 miles drive and placing the car in park with the engine off, the passenger door would not open from inside or outside of the car. The issue appears to be an electrical, because the central locking system would lock the car, but would not unlock. The driver door does open from the inside but the passenger door does not. This could be catastrophic in case of fire or accident.”

NHTSA complaint #11231896, filed 2019-07, 106,000 miles

“Drove car at approximately 8:30 p.m. Car was left in the garage for the night. At 3:35 a.m. Was awaken by my dog and smelled smoke, strongest in the area of the garage. Once extinguished by firefighters the car was pulled out. The left front number, headlight, and adjacent structures were melted. Extensive fire damage and smoke damage in the garage, and a lesser degree in the house. Cause of fire origin was not determined, but the car was not excluded. Concerned that this could be related to the auxiliary cooling pump issue noted in 2010 and 2011 models.”
