I haven't noticed anything on my 06 like this.

Maybe the door isn't aligned properly? Maybe the door or window trim isn't installed properly? Perhaps there's a problem with that strip that keeps the window clean (and scratches tint jobs)?

It's hard to say without actually being there. I hope someone who has had this problem before can chime in...

Congrats on the car (if you just got it). It's funny how we both have the same join date...although as I remember it (when I was an avid user here), the database was wiped and I had to re-register.
