Review of the 2003 GMC Sierra 1500

  • Powerful drivetrains, classic exterior styling and unique options make the Sierra a pickup worth considering, but Fordís new F-150 has it beat when it comes to interior design and overall refinement.

  • Safety
  • Pros

    Roomy extended-cab models, strong V8 engines, innovative features.

  • Cons

    Spotty fit-and-finish concerns, low-grade interior materials.

  • What's New for 2003

    The Sierra gets a revised look this year that includes a new front fascia, revised side moldings and an additional wheel design. Top-of-the-line models get power-folding heated mirrors with puddle lamps and turn signal indicators. Inside, the Sierra now offers a Bose stereo system and XM Satellite Radio. The instrument panel and center console have been redesigned, and GMC has added new seats, a more comprehensive driver information center, optional satellite steering wheel controls and a dual-zone climate control system. For increased safety, Sierras now feature a standard front-passenger-sensing system and dual-stage airbags. All 4.3-liter V6-equipped Sierras and California-emission V8s are now ULEV certified, while electronic throttle control is now standard on all V8 engines. Finally, the Autotrac four-wheel-drive system has been modified for less intrusiveness at low speeds, and the brake system received upgrades that provide better pedal feel and improved overall performance.

5.3 v8 why go smaller?

Vehicle: 2002 GMC Sierra 1500

I have a 2002 GMC Regular Cab Flareside shortbed 4x4. I bought the truck used with 46,000 miles on it and now have 51,000 and only had one problem. My sound system rattled the screw loose on the overhead consule. I installed the sound system a month after i bought it and it and had to replace the tires which seem to be a common problem with these.I have a hard tonneau cover and it really helps out living in Alaska. If a truck survives here it can survive anywhere.




Absolutly satisfied

This truck is awesome. Only had one problem with it and that was the intermediate steering shaft replaced at no charge. The 4.8 had plenty of grunt. Spins the rear tires no problem (even at 1/4 throttle). The 4 wheel drive just goes in the snow no spin at all. It tows like there's nothing there which is awesome. It gets very decent gas mileage too I get about 17 18 city.




A fairly good all round

Vehicle: 2002 GMC Sierra 1500

Bought this truck in Feb 2007 with 86,000 miles. At 89k new fuel pump b/c previous owner did not change fuel filter. At 92k intake gaskets leaking bad enough it wouldnt run on a cool summer morning. 93k discovered the reason behind poor braking was that the front rotors where virtually destroying themselves. Terrible case of piston slap when stone cold. Other than these problems I love my truck. It's quick nimble and fun to drive. It is crazy good looking. I drive it extremely hard about 3/4 of the time and it doesnt miss a beat. K&N filter helps power.




Gmc 1500 lemon

Vehicle: 2002 GMC Sierra 1500

The truck ran and performed fine up to the point to where I had about 8000 miles on it. After that, engine knocks, transmission slips, steering problems, brake problems, gas mileage dropped, tires were wearing funny, brake light electrical problems all surfaced. Maintenance shop was cluless on fixing problems and didn't know how to fix anything. I was accused of 4 wheeling the truck when I have never even had it off road. Then I was told that the steering problems, brake problems, and tire problems were not covered under warranty past 1500 miles. Worst truck I have ever owned and I'll never own another.




Great value

Vehicle: 2002 GMC Sierra 1500

Purchased used and in great shape. Runs strong and looks new. Fuel mileage is around 18mpg. This one has the 34 gal tank and a 373 posi rear. Fast acceleration and great braking. Trailering package stiffens the ride but it is a truck after all. Very pleased so far.




Gmc forgot driver's side ergonomics

by on
Vehicle: 2002 GMC Sierra 1500

Although the engine has spunk, the 4x4 feature is only suitable for driving straight. While executing even wide turns in 4x4, the entire vehicle shakes and makes squeeking and grunting noises. Traction on any wet or winter surface without 4x4 is non existant without a load in the long bed. The legal heavy load capacity is limited to just a few hundred pounds above the vehicle's own weight. Inside the cab the driver's side is very narrow, forcing you to place your left elbow against the solid door. This results in constant elbow bruising. I must always wear a thick left elbow pad to prevent pain and bruise. The seat is also too narrow, binding the outer right thigh. At 5'8", I'm dissapointed.
