ok i recently just encountered this trouble with my tl as i'm dringing over a moderately bumpy road i could hear this ANNOYING rattle in my passenger door panel. sounds kinda like metal on plastics. Brought it to the dealer they say they fixed it but still the same $hit.

PLEASE HELP!!

 

Welcome to the 3G TL my friend.. it's the like the Where's Waldo of Rattles.. lol..

Live with it.. or try to dampen it yourself.. otherwise it'll spend half its life in the service center for the rattles.
