Many problems with this 2000 Jimmy. Bought it used from carmax at 18K miles on Jan 2003, got ext. Warranty, but soon after, front brakes need to be replaced, replaced by carmax for free, but 6 mos later brakes needed replaced. Was advised that rear rotors and brakes were almost at end of life. 9 mos later, replaced rear brakes and rotors, not covered under warranty due to wear and tear, spent $450 as well as replacing serpentine belt and flushing break fluid, total cost $650. Problems with sunroof started in Apr 2003, it finally stopped working and was replaced at 43K miles under ext warranty, had to get new battery, noise in under carriage on drivers side, determined to be problems with hub bearings and idle arm, inner tie rod, all replaced under ext warranty, total cost would have been $750.
