This has happened to both of my windows.. its kinda annnoying because now I am super cautious when I roll my windows up I try not to hold too long or press the button too much checking to make sure the windows are all the way up. On top of it my Passenger window button likes to hold like its sticky internally or something like that because it doesn't just snap back (like the driver button right next to it) and causes the system to continue to roll the window up after I have let off.. oh the small imperfect things that get to you ya know? _end rant.
Oh and I am a huge fan of the new wheels. I swear I put those on everyone of my cars in Forza motorsports. haha.. anyway. Keep it up man. "If you buy them.. the parts will come."
