Edmunds' Expert Review

by the Edmunds Experts

Pros

Powerful drivetrains, roomy interior, numerous available amenities.

Cons

Spotty build quality, cheap interior materials.

What’s new

Base trucks get upgraded via newly standard cruise control, chrome wheels, chrome rear bumper and chrome grille surround. The SLE trim adds foglamps to its generous list of features. The Work Truck Package (with unique grille treatment) is now available on all models. Lastly, a trio of new colors, Sand Beige Metallic, Silver Birch and Sport Red Metallic debut.

Edmunds says

With its powerful engine lineup and revised interiors, the heavy-duty Sierra makes a strong case for itself against the competition, but questionable build quality keeps us from calling it best in class.

2004 GMC Sierra 2500HD 4dr Crew Cab SLT 4WD SB (6.0L 8cyl 4A)

Truck has been overall a good unit. Windsheild leak when new at passenger floorboard and behind dash. Took 1 year for local dealer to finally fix. Climate Control slow to activate fan, really noticable on hot days, seems I have to press brake pedal to start blower (wierd). Trans will sometimes start in 2nd gear, then shift to 1st. Usual problems with intermiediate steering shaft (now …

2004 GMC Sierra 2500HD 4dr Crew Cab SLE 4WD SB (6.0L 8cyl 4A)

Absolutely the best truck I have ever owned. During it's maiden break-in run I got 23.8 mpg. When engine is broken in mileage should be even better. I drive between 55-65 mph and this seems to be the "sweet spot" for performance. Got it to haul our slide in camper and this will be no problem now. (Not like our 91 Silverado which on it's best day with only one person …

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

I researched long and hard when deciding on the $$ for the Duramax/Allison combo. Man am I pleased! It pulls my travel trailer like it wasn't even there. MPG has been better than my previous Firebird. Comfort is much better than I expected for a 3/4 ton. Looks? Man, you can't beat the Fire Red color! Don't know what it might take to wipe this smile off my face!

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

2003 Sierra with 8.1 liter 345 HP and Alison Auto. Plenty of power for towing. A little hestitant on take off when cold. 20,000 miles in 6 months and it runs like day 1. Fuel mileage is absolutely HORRENDOUS!!!! Towing an enclosed race car trailer x-country avg. mileage = 7.95. Driving enmpty no load at all avg. mileage = 12.98.
