  • What's New for 2003

    The Sierra gets a revised look this year that includes a new front fascia, revised side moldings and optional multifunction, fold-away mirrors. On the inside, GMC has added new seats, a more comprehensive driver information center, a redesigned instrument panel and optional dual-zone climate control and satellite steering wheel controls. On the hardware side, the standard 6.0-liter V8 gets electronic throttle control as well as the ability to run exclusively on Compressed Natural Gas (CNG) or a mix of CNG and gasoline. Other upgrades include an improved Insta-Trac part-time four-wheel drive system for reduced service costs, a more efficient starter for the 8.1-liter V8 and a revised headlight switch that allows drivers to turn off the daytime running lamps.

Vehicle: 2003 GMC Sierra 2500HD 4dr Crew Cab Rwd SB (6.0L 8cyl 4A)

Disappointed in the power. Tried to pull a 16' stock trailer with two bulls. It was all it could do to get over a small hill. Constant air conditioning problems. Unscrupulous dealership tells me it has been repaired. Lies. Electric window problems. Needs larger fuel tanks for a truck that gets 13mph. Wears front tires knobby. Stress cracks in the windshield. Brakes squeel. Tapping in the engine. Would I buy again. No Chance. Off to the dealership for engine noise;AC repairs again. Watch out Ford/Dodge, here I come.
