Example complaints

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

“Rear tailgate window hinge broke while having the window only open and putting away groceries. Upon closing the window, the right hinge broke causing the window to almost fall off of the car. I attempted, with assistance from others in the parking lot, to push the window back into the frame and have it lock at the center latch. The latch is no longer engaged and I have attempted to push on the window to connect with the latch. I am not strong enough to do so. The window is at a point where it could fall off of my car. …”
