Bought this truck in 2003 with 35k on it. have put 100k on it since then. steers more like a mini van than a truck, rides better also. Have replaced every power window motor at least once, replaced transmission at 105K have replaced 4 oxygen sensors and still have engine trouble light on. push button 4 WD switch doesn't always work, door locks occasionally don't work, check 4 WD light comes on but no mechanic can figure out why, wheel speed sensor in front wheel hubs were repaired under recall once but again don't work causing ABS to activate at speeds less than 5 mph such as when you are trying to stop at a redlight, causing brakes to not work, have had several near fender- benders.
Room, ride, towing and cargo capacity is tremendous. 5.3 L engine gets 15 around town and 20 highway with 7 people in the vehicle.
rear quarterpanels rusted in front of the rear wheels, apparently they all do because of some GM body or paint defect. check quality controls
