Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“A small spring inside the door lock breaks which keeps the door from opening once locked. I have seen many repair how to videos on youtube about this issue. It is a serious safety issue. If a person is in an accident and needs to exit the car quickly, this broken lock can keep them stuck inside the car unable to escape.”
