Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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!
