Re: Window squeaking sounds.
My driver's side window has the same sound when it rolls up and down occasionally. At first I thought it only happened when it was warm outside but it happens off and on with no rhyme or reason. I did have the dealership adjust the windows travel limits (driver's side did not go all the way down completely. It was some memory issue) but the noise is still there. Doesn't seem to be wearing on the window or anything. Maybe a tight fit. I've got about 4000 miles on it now and I use the window at least twice a day to get in and out of my parking garage so it should be well past any "break-in" stage.
