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.
Reliability improvements for all Vortec V6 and V8 engines top the list of changes this year. Consequently, oil-change intervals have been extended to 7,500 miles. A traction assist feature is now available on two-wheel-drive V8 automatics, thanks to a new electronic throttle control system. Factory-installed OnStar, GM's mobile communications and security system, has been made standard with the SLT trim level. New this year is a 325-horse, all-wheel-drive performance version called the C3.
