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.

  Poor Ride with wheel vibration - 2003 GMC Sierra 1500
  By Timmcp - October 30 - 10:00 am

  After about one week of driving, the truck began to vibrate excessivly especially on concrete freeways. Took it in 4 times, each time the wheels were way out of balance. They cant figure it out. They think that maybe the tires are moving on the rim. These are Bridgestones on aluminum wheels. It turns out that you may get Bridgestones or Firestones(same ones recalled by Ford) depending on what they have laying around at GM. It is made worse by a poor suspension design that does not perform well at highway speeds. At this point the tires are still out of balance and the dealer doesnt know what to do or what is happening.
