Overview & Reviews

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.

• Powerful V8-engine selections, handsome styling, comfy cabins.

• Spotty interior fit-and-finish concerns, premium brand carries a premium price.

  Whoa there - 2001 GMC Sierra 1500
  By KNOCK KNOCK - May 19 - 10:16 pm

  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.

  Not bad! - 2001 GMC Sierra 1500
  By xfarmboy - April 24 - 2:00 am

  Bought my Sierra new and still enjoy driving it. Only had a few warranty items to take care of in the first year (rear seatbelt retractor, clunking sound from front wheels when going over bumps & front wheel alignment problem). Other than that, have just had it in to the dealer for regular maintenance. It handles great on curves & turns and has plenty of power. However, it does drink lots of gas. I average about 13.5 mpg in the city & around 16 mpg on the highway. The factory tires were terrible (Firestone Wilderness AT) and I only got about 36,000 miles out of them. Have replaced them with Michelin LTX M/S and they have been great in giving the truck a much smoother ride.

  Super truck - 2001 GMC Sierra 1500
  By Timster - September 20 - 2:00 am

  looked at Ford and Dodge...but after I test drove this one, I knew this was what I was looking for, my only regret is tha I didnt get the full front- hinged four door, and that GM doesnt offer it other than with the 6.0 300 horse engine, my extended cab 5.7 litre V8 has 285 H.P. but gets over 5 miles to the gal. better than the 6.0.....to big of a trade off for 15 horses. But I love the truck!

  Still love it after 9 - 2001 GMC Sierra 1500
  By CLIFFMO - July 29 - 3:46 am

  110000 mi and still original brakes and I tow a 5th wheel. Always serviced at dealer. Drivers seat leather needed replacement - outside edge, otherwise excellent wear and reliability.

  Pleased with my Sierra - 2001 GMC Sierra 1500
  By MrSkimo - July 11 - 10:00 am

  I love my truck...most of the time. It has been 100% reliable. Excellent mechanically. The interior is a little cheap feeling with lots of hard plastic. The one complaint I have is soft paint. Rock chips and scratches on the body from branches are horrible. The dark red paint has a white primer which shows everything.

  I have had no problems at all with this truck. It can haul, cruise, or simply get around town with no problems.

  Rusting away - 2001 GMC Sierra 1500
  By Brian - June 18 - 12:10 am

  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.

  Best vehicle Ive owned - 2001 GMC Sierra 1500
  By KFayal - April 11 - 10:00 am

  I love this truck. I have the 5.3 liter V8 Sierra 1500 SLT. This truck is almost like a car in comfort and features. For the driver and passenger its hard to tell that you are in a truck. The engine has power on tap. Almost 2.5 years of ownership and Ive had only one small manufacturer warranty item replaced: the gas gauge.

  sweet truck - 2001 GMC Sierra 1500
  By tjones - February 8 - 10:00 am

  All the LS! based engines knock @ startup and seems to be less of an issue as miles add up/mine is 5.3 with towhaul opt.Smooth and tomb like quiet @ 80mph. 3:73 rearend pulls like crazy (I can pull my 245500lb boat and tandem trailer with ease. I had dealer send out and install leather in the 40/20/40 split seats(better leather than factory too. Ive driven trucks 35yrs/ Ford150/slverado1500s(the chevy never left me stranded in 200k/ford let me down @ 150k.So far,this is the best one I have ever owned. Try adding an extra quart of oil. 22mpg hiway beats the 12 and 14on the chev and ford.
