I am reporting the malfunction and separation of the rear window from the cover. This is a safety issue as there is the potential for it to come off while driving and possibly causing an accident. It started small, but has grown to almost 12 inches. I have not yet found anyone who has the capacity (or desire) to fix this. And those that actually want to take on such a project are charging over $5,000! Please help!

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
