The rattling actually started after putting the roof up manually following the procedure in the manual but before the dealer did anything. The back of the roof by the glass is not down tight. Also...the rear defroster and manual spoiler deployment buttons don't work making me think it may be electrical problem of some sort.

I checked the fuse box....found some of the spots had higher amp fuses than what was listed in the manual. Don't know if that is a problem or not.
