The driver's window is broken off the track and has to me coached up 70% of the time. It broke right after the warranty ran out. I feel the warranty is weak 36 months 36,000. It should be at least 6/60. Then a pulley went that controled the belt and had to be replaced, that happened during the first 20,000 miles and the dealership fixed it free of charge.
I feel that for the money the Chevy Tracker is a good purchase. The only thing I wish is that it has just a little more cargo space. The head room is good, but if your planning to carry anything it becomes a 2 seater and then you have to choose between cargo and people.
Window bolts securing the raising mechanism are probably loose, requiring the removal of the side door panel, electrical connections in the window corner, window connections in the arm rest. Window must be secured with pressure away from the front window guide. Lubrication on the front window guide probably a good idea. Dry graphite may help prevent sticking/loosening, too. Suggest the library for a good repair manual to prevent plastic pieces from breaking behind the door handle, which the side panel "spins" around. Thin, flat bar helps remove push-in fasteners. Only do this when you are not in a hurry, and you are mechanically savvy.
We have owned a 2000 tracker for a short while now, and it has been nothing, but a noisy-undependable-uncomfortable-expensive to repair piece of junk from the GM line. We will never-ever own another tracker!!!
