I had the same rattle in my sunroof I opened it and noticed there was a loose piece of trim connected to the moon roof (glass section ) once I re attached it the noise went awayAnyone have a rattle on their sunshade in the ceiling toward the back of the truck? When I hit any bump it rattles. Also still have a rattle near by back window. Had a loose subwoofer and fixed that but there is still a rattle. I will been looking.
