Anyone develop an annoying under-dash rattle? Mine sounds like a couple of small BBs in an empty beercan. (I know this isn't it because I drink out of bottles...just kidding!) I will probably bring it in to the dealer next weekend for this, a rough idle, the mismatched radiator problem, and a lube/oil/filter. If anyone has a suggestion for the rattle, I might be able to point the service manager to it better...

Thanks!

Interestingly enough, I just noticed this today. I haven't gone looking for it, but dtrosch's description is apt - a BB in a beer can.

dtrosch, I had a similar sound when I bought me screw. dealer found a loose support under the dash by the passenger side air bag. My dealer has fixed the few problems I have had so far with the exception of the wrong radiator.still working on that one. good luck
