Review of the 2001 GMC Sierra 1500

  • 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.

  • Safety
  • Pros

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

  • Cons

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

  • What's New for 2001

    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

by on
Vehicle: 2001 GMC Sierra 1500 4dr Extended Cab SLE 2WD SB (4.8L 8cyl 4A)

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.




Rusting away

Vehicle: 2001 GMC Sierra 1500 4dr Extended Cab SLE 2WD SB (4.8L 8cyl 4A)

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.




Dependable ride

Vehicle: 2001 GMC Sierra 1500 4dr Extended Cab SLT 2WD SB w/OnStar (4.8L 8cyl 4A)

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.




Still love it after 9

Vehicle: 2001 GMC Sierra 1500 4dr Extended Cab SLE 2WD SB (4.8L 8cyl 4A)

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




Whoa there

Vehicle: 2001 GMC Sierra 1500 4dr Extended Cab SL 2WD LB (4.8L 8cyl 4A)

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.




Very reliable

by on
Vehicle: 2001 GMC Sierra 1500 4dr Extended Cab SLT 2WD SB w/OnStar (4.8L 8cyl 4A)

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.
