Review of the 2003 GMC Sierra 2500HD

  • With its powerful engine lineup and revised interiors, the heavy-duty Sierra makes a strong case for itself against the competition.

  • Safety
  • Pros

    Powerful drivetrains, roomy interior, numerous available amenities.

  • Cons

    Spotty build quality, cheap 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 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.

We have a 2003 gmc that's been a nightmare.the horn keeps blowing fuses,won't start in park,no reverse fuel light doesn't 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 hasn't been fun. Anyone looking to buy a new truck be careful,when you pay 45000.00 for a new truck you don't expect this.
