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.

lemon - 2003 GMC Sierra 2500HD
By darlene - July 4 - 10:00 amWe have a 2003 gmc thats been a nightmare.the horn keeps blowing fuses,wont start in park,no reverse fuel light doesnt work plus the gas gage stuck on and the thin plastic bottom part of the bumper crack. Trying to get the dealer and gm to take this truck back hasnt been fun. Anyone looking to buy a new truck be careful,when you pay 45000.00 for a new truck you dont expect this.
