After 13 years and 252,000 miles, i think it's time a write a review. The engine is all original, and runs as good as the first day. The transmission failed after 150,000, but the new one is flawless. Aside for the normal consumables, I have had to replace one wheel bearing. That's it. That, and the fact that I have two rather expensive cars sitting in the garage, but my wife always prefers the "truck" for it's comfort and ride quality. I'm sure someone out there will beat me up on how much better they're doing with their Ram or Ford or Toyota, and I can't fault them... I don't know those trucks. But this truck doesn't show any signs that will give it up any time soon.
I have had fuel line, brake line rust problems, I have also had rear brake problems having 4 sets of brakes on the rear since purchase. Very disappointed in this truck. Steering noise problems. And from talking with other owners these problems are common place with GMC and Chevrolet 2001 trucks.
Better quality steel and go back to rear drum brakes.
purchased new in 01,in 8 yrs the truck has had very few problems. passenger side seat belt tightens up on its own, & the interior light switch had a short.Oe tires had to be replaced at 35k, & the on star system is no longer compatible with the new digital system. fuel mileage averages about 17 in mixed driving, 20mpg is achievable on long highway travel.I would buy another gmc if we wear this one out, brakes still have about 60% life left.
Heated leather seats, whole interior is comfortable & user friendly.Easy to change halogen light bulbs.Reasonably Quiet ride, & decent handling for a truck.
Truck runs good but there have been some problems. The brake light goes on most of the time, brakes are in working order says dealer. I need plenty of distance to stop. Gas gauge goes up and down intermitantly if you fill-up, at 1/2 tank it will go away. I have racks and boxes which has made body panels break away at tailights. Pro-grade not. Response was too much weight on bed? Vibration or shudder on launch. Mechanic found bearing in tail of tranny is worn. Remove to repair, too much weight?. Engine knocks on start still, response was could not replicate. Taigate cables were only repair that was correctly solved. The rusty bumper+driveline clunking was ignored.
The 5.3 motor and locking differential are working still (knock knock).
