I have started to noise that I have a noticeable rattle noise coming from the ceiling/canopy of my new LTZ. I have a moon roof and was able to remove the rubber molding and take a peak around. Not too much up there. But there seems to be a magnet that keeps the canopy taunt to the roof. However, the is a large amount of space. I think it may be the materials used in the padding/spacers that are in the ceiling. Has anyone else noticed this. Also..the drivers seat makes alot of noise when I shift positions just slightly. It seems to be related to the power seat mechanism. Any way to lubricate this?
