I have the sunroof rattle, but I can tell that the sunroof is actually slightly loose when closed. If you push up in eithe front corner there is a little play. Mine has more play on the right side. This I believe might be a major culprit for rattling sunroofs. Does anyone know how to tighten this more secuerly to the rails?
Thanks.

 

I had that annoying rattle too...i ifxed it and now its gone....if ur car is fairly new, i doubt that it is loose....All u need to do is go to pepboys or sumthin and buy a can of all purpose LITHIUM GREASE.....take a glob onto ur index finger, and work your way around the edge of the rubber seal....tilt position to reach the rear side....and wha LA...the rattle is gone...re-apply when needed....the rattle is the rubber seal rubbing on the roof....thats y it goes away in tilt position or when its fully open.....Some pple say to use silicone grease, but ive looked all over and couldnt find it....please let me know if anyone knows where to get it.....i think they are all the same anyways....hope this helps

 

Just bring it to the dealer if your car is still under warranty. There is a TSB on the sunroof rattle issue.
