I have a 2011 Laredo with a sunroof (not the panoramic) with only 500 miles and I had a rattle only when it was in tilt/vent mode. I found that there was a piece of plastic in between the glass panel and the bottom of the opening in the rear and this was loose. It would hit against something when I would go over bumps causing the rattle. Took it to the dealer yesterday and showed them the problem. When I picked it up, they said they didn't find anything missing, but the insulated it so that when it moved it wouldn't make a noise. Does that seem like a good solution? Does anyone else have this issue when the sunroof is just tilted?
