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!
