Example complaints

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

“It is probably a shorter list to list what we haven't had trouble with , but here goes. 1. The back power sliding doors will open and shut at will. Driving down the road, parted in the grocery store parking lot, etc. The neighborhood kids regularly come over to tell me my doors are open. My husband almost missed a flight because he spent to much time trying to fight with the door to stay shut. They have replaced almost every part of the doors several times, but was told by the dealership that last time I took it in they didn't know what to do now. 2. Door locks will lock and unlock at will. …”
