I know there is info on this and there were a lot of posts a yr ago when I first joined, but does anyone have a solution to this? This is the only issue I am really having with the car that the dealer doesn't seem to know how to fix. Both door panels have been replaced and they apparently have removed most of the grease from the tracks. I am getting it in the middle of the window. It appears the driver side has been cured, but the passenger side still gets it.
