My sunroof on my '02 EX was squeaking and rattling like crazy, I know this is a common problem with the Accord, but this was getting REALLY annoying. So, being due for an oil change, and knowing that it was free (I have a preferred customer card thing that the dealer was offering when I bought the car), I decided to complain about it at the dealer and see what would happen. I was surprised to find out that apparently there's been a service bulletin and they corrected the problem with some shims and some sort of sound-deadening material (none of which I can actually see). Believe it or not, the thing is dead quiet now. So if any of you have been putting up with the sunroof making noise, make sure you get it checked out if you're still under warranty. Let the dealer know there's a service bulletin out there. Hopefully you'll have the same luck I did.
