the first in my TSX actually. It's from the sunroof or something. It rattles when the sunshade is open. So freakin annoying. When I close it, the noise is gone or minimized. I have a similar problem in my integra. Was never fixed by the way. Anyway, just thought I vent a little.

 

Had the same rattle (I have them all) and the dealer fixed it by putting clip in somewhere.

wipe down all the seals with whatever you use on your tires and it will go away. There are threads on this so try a search.
