Summary

What Edmunds.com says

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

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.

2003 GMC Sierra 2500HD 4dr Crew Cab SLT 4WD SB (6.0L 8cyl 4A)

The torque and power of the 8.1L is incredible, but be aware at the gas pump. An average of 9.1 mpg will be all you'll get. Towing large campers or trailers is no trouble what-so- ever. Especially in lower range gears the 8.1L begs for more. All around I love the truck, including a great interior and stock stereo.

Power, comfort, heated seats

Mileage gain of any would be great. GM needs to get on the ball with some reliability issues.

2003 GMC Sierra 2500HD 4dr Extended Cab SLT 4WD SB (6.0L 8cyl 4A)

The Isuzu engine is the best part of this truck, along with the Allison tranny. The worst part has been all the GM stuff. Everything from numerous AC problems to leaks, memory features deleting themselves, multiple transfer case problems for auto 4WD, and leaking fuel injectors. If it were not for the dealership's attitude and incompetance i would buy again.

Awsome torque and power. Best seats available in any vehicle that I've tried.

Roof is very flimsy, needs reinforcement. Major quality improvements needed overall. More wheel selections, realistic/competitive fees for on board phone service

Best pickup I have ever owned, plenty of power and is very comfortable

Duramax and Allison combo

Go to a solid front axle instead of IFS
