I am experiencing the exact same problem. Every time I roll over the slightest bump in the road the driver window rattles at the lock. Don't seem to notice a rattle when the window is completely down. I'm going to try the dealer first but in a way I'm glad to hear that others are reporting this annoying problem.

 

Anyone ever figure it out? I took the panel off and tried to fix it myself, since the dealer has not always done a great job for me. I did find the clip that holds the lock stem in place moved and made a tic noise. I put some friction tape under it and that stopped the noise. I also tapped the speaker wire to be safe and still when making a turn or hitting dips I get a tic noise coming from appears to be the lock area meaning the portion of the door closest to the latch. Same as other described that with the window down an inch or two it gets louder but all the way down I did not seem to hear it. I was wondering if there is a cable in there that tightens up when the window is down. Since it is under warranty, I did not want to pull anything off more than the panel. That said, I rather not visit the dealer for convenience and quality reasons.

 

Rattles like a **** with the music on
