very reliable
The best car/truck Ive ever owned. I trust it to go anywhere.Has towing package but anything 7000-8000lbs fells like a struggle for the engine. Like the 4 wheel disc brakes.Factory a/c delco batteries gave trouble(leaked acid). In 91k miles only 1 visit to dealer to repair abs warning light(abs unit died). The drive train is good(change limited slip gear lube every 30k miles) or limited slip rear can stay locked up after a hard acceleration.)Truck has been lowered 2-4 inches (It sits nice, not too low). Installed airlift load assist air bags for towing/hauling (highly recommended!) Flowmaster 70 series dual side exhaust system. 20 inch centerline wheels. The truck 'Ive always wanted. Very happy.
Good truck with lots of extras
I have 11,500 miles on this 1-year old truck. I've owned many vehicles in my 25 years of driving, and honestly think this is the best truck on the road. The ride is smooth (better than many cars), the 5.3 liter engine is strong, and the fuel mileage beats the heck out of a Dodge. I've owned Chevy and GMC trucks before, and I agree with many other people who say the re-design of these vehicles put them in a class to be envied.
Rusting away
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.
Wish I bought the Tundra
At 900 mi It was in the shop for clunk/bang/vibration in the drive train. . after several annoying/time consuming attempts. GM bulletin (drive line clunk)#99-04- 02-002A. Not to be confused with the engine clunk/piston slap bul. This truck acts and sounds like the 1996 I sold prior. with 150,000 hard miles. I'm finding out that there are many bulletins and dissatisfied customers with several of the 00/01/02 model yrs. It now has 10000 mi and I'm sorry I ever bought it!!!
flimsy body panels
Be aware of service bulletin # 01-08-66- 014 which addresses sheet metal fracture with accessories such as tool boxes,and ladder racks. My truck has a rack on it which was also on my '99 GMC(which had no problem in 94000 miles).At about 70000 miles the body panels just in front of the tail lights on both side ripped apart and the bed rails collapsed onto the tail lights. Since I am out of warranty(too many miles, not time) that this repair is on my dime - actually $1800. This was my third truck from this dealer and all of them have used the same rack. They told me that when GMC went to the new body style in 2000 they just aren't as strong. BE AWARE!!!
