Shortly after purchasing my '01 vehicross in April of that year, the passenger window began rolling slower and slower and popping off the tracks, until finally it stopped completely altogether. I took it in and Isuzu replaced the tracks and fixed that side altogether.
Then about 6 months after that the driver side did the same thing. They replaced that track and fixed that side, so far.
So, we know it is not our fault, nor any other fault such as tinting, etc....
