Has anyone else had an issue with the panoramic moon roof vibrating on one side when closing. It seems to close and seal just fine, but noticed after a recent 20K service at the dealer that the right side of my moon roof vibrates a bit when closing. I called the dealer in Sacramento, and they said that they don't do anything on the 20K service that would have caused that. Unfortunately, the CPO warranty. (only had the car 6 months) will not cover anything to do with the panoramic moonroof. They also would like $325 to diagnose what's wrong with it. I rarely open it all the way, so I may just not worry about it. I usually just crack its open. Any thoughts?
