The closed moonroof (with shade open) is the most annoying rattle in the car. It is so bad that I can't keep the shade open when the moonroof is closed! Too bad, because I have otherwise been happy with my '01 CL-S. I will be giving it back (lease) this Sept and most likely buying an Accord EX cpe.
From what I understand from the dealer, the moonroof rattle is common on the 01-02 models. Nothing really the deal can do.
Oh well.
Cheers!
