Edmunds' Expert Review

If you want power, the Sierra's got it. But if high-quality materials and solid build quality are also a priority, you might want to check the offerings from Ford and Toyota, as well.

vehicle overview

After a much-improved Sierra bowed in 1999, GMC's full-size pickup continues along the refinement trail for 2001. The Sierra 1500 (half-ton) employs a unique, three-piece frame construction. While it shares a platform and componentry with Chevrolet's Silverado, the Sierra gets some styling and feature enhancements to position the GMC as a "professional grade" truck.

Looks and special content aside, the biggest draw for GMC's half-ton pickup is a first-class engine lineup. The base 200-horse, Vortec 4.3-liter V6 has been upgraded again this year to improve durability, emissions and fuel economy. But more impressive are the two available V8s, all of which have seen further refinements to reduce NVH (noise, vibration and harshness) and increase service life. The Vortec 4.8-liter V8 (with 270 horses/285 foot-pounds of torque) is standard on half-ton extended cabs, and a 5.3-liter V8 (with 285/325) is optional on all 1500s. Both enjoy a flat torque curve for sustained hauling power.

Each version is available with a five-speed manual or four-speed automatic transmission. As usual, there is a variety of configurations to choose from, including the regular (two-door) or extended (four-door) cabs, short (6.5-foot) or long (8-foot) beds, Wideside or Sportside box designs, and rear- or four-wheel-drive versions. What's more, there are three trim levels (SL, SLE or SLT) and a dizzying array of options and packages to custom equip your truck exactly the way you want it.

Do you go off-roading? Choose the Z71 Off-Road Suspension package. Prefer to pick your own suspension settings? Try the ZX3 Manual Select Damping package. Plan to do a lot of towing? Go for the Z82 Heavy Duty Trailering Equipment package. Got heavy loads to haul? Opt for the Z85 Increased Capacity package. Like performance? Order the new C3, a sporty, high-end AWD model that's available only as an extended cab and built as a more practical alternative to Ford's supercharged SVT F-150 Lightning. The Sierra 1500's roomy interior offers ample storage space, including a center armrest that is large enough for a laptop computer or a six-pack of soda, depending on your priorities. Reduced-force airbags (with passenger-side on/off switch) are standard, plus a full complement of safety and convenience features too numerous to list here. Overall, Sierra is very competitive with the top Ford and Dodge offerings. But because GMC is now defining itself as the "professional grade" division for more demanding truck buyers, watch for price creep to start forcing less-affluent young cowboy types to look elsewhere.

2001 Highlights

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.

A real long term test
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. Thanks to Edmunds for the opportunity to provide my last review at 279,000 miles. My last because it's been passed along to a father who needed to haul his son to all the bike races around the state of California. At that time the truck was still flawless, and I was very confident it would soldier on for them.
dependable ride
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.
I love this truck
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.
Pleased with my Sierra
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.

Should I lease or buy a 2001 GMC Sierra 1500?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
