I did a search and didn't find many threads on rattles, so I thought I'd start this one.
There's already a long thread on the squeaks from the center console (by the shifter) which is quite extensive including solutions.
I have rattles coming from both front doors, passenger worse than the driver's side. It goes away if I lower the window a hair, so it must have something to do with the power window mechanism. I will be having the dealer check this one.
I also have a rattle coming from inside the dashboard. It's a sharp sound expecially when hitting expansion joints.
If anyone has these rattle or others and has found the source I'm sure we'd all appreciate them. Dealers are really bad at finding and fixing rattles (Most of the time they don't believe me when I tell them!

)
