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.

  GMC Sierra - 2001 GMC Sierra 1500

  We bought this truck with traveling in mind. Havent retired yet, but we drive the truck every day and also driven it during vacations. Its equipped with a vortec 5.3L engine; in our opinion one of the best; along with many ammenities. Weve driven it for 5 yrs and its reliability is second to none. The cruise control is simple to use and the large bucket seats are comfortable. Also like the tilt steering wheel.

  I love this truck - 2001 GMC Sierra 1500
  By drgroth1 - October 29 - 3:00 am

  I have driven this truck cross country several times, a few of these trips required towing another car behind. I went through Colorado and had no trouble keeping up with the rest of the traffic even though I was fully loaded and towing a loaded car behind me up the mountains. I have driven in snow in Minnesota and even though I do not have four wheel drive I did not have any problems, I did have snow tires installed. I get 20mpg, which is great for a truck. I cannot say enough good about this vehicle.

  dependable ride - 2001 GMC Sierra 1500
  By alphonse - February 5 - 2:13 pm

  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.

  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.
