Overview & Reviews

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.

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

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

  Screw the competiton BUY THIS TRUCK - 2003 GMC Sierra 1500
  By Z71-Stud - September 22 - 2:00 am

  Out of all the trucks I have ever owned this has to be the best! From the well thoughtout interior, powerful vortec engine, and classic styling I really cant ask for too much more. Well then again; Hey GM, how about a big block option!

  I use this truck every day for work and pleasure and it always serves me very well. I even used it to pull out a big lifted Ford from the mud.

  What a Ride - 2003 GMC Sierra 1500
  By dcintron - May 11 - 2:00 am

  Vehicle weight makes for a comfortable ride. Handles the interstate like a luxury car. The Quadrasteer feature makes moving around the city a breeze. Parallel parking and parking garages with appropriate height clearance are easy to handle. The Denali has good acceleration. Does not get blown around when passing the Big Rigs. Dont expect better than 14 miles per gallon, about 13 mpg at 80 mph. Once youve driven the Denali youll never want another full-size pick-up without Quadrasteer.

  Best Pickup On The Road - 2003 GMC Sierra 1500
  By Del6389 - January 4 - 2:00 am

  I couldnt ask for better handling, a better ride, or more power. This vehicle blows the competition away. Quadrasteer makes parking & curvy road handling a breeze, sticks to the road like its mounted on rails. Interior quality is the best Ive found anywhere, the heated leather seats moulds to your body for the ultimate seating comfort. Onstar is a must for safety & convenience. XM satellite radio is better than having a hundred CDs, also the Bose sound system quality is second to none. Select ride smoothes out the bumps in the road lmost as if they didnt exist.
