Edmunds' Expert Review
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 Highlights
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.

Montana diesel,02/24/2010
I have the 2nd generation LLY Duramax engine in mine and i love it. I had to replace the injectors when i bought it at 130,000 but other than that i have just been upgrading. The ride is great, the seats are comfortable, the fuel economy is good, 20-24 highway, 15-18 city, if i keep my foot out of it(hard to do with 400 HP and 600LbFt of torque on tap). I have not had any major breakdowns since owning it. The transmission did blow up at 143,000, but it was a freak electrical short that caused it to engage 2 gears at once(lots of chunks in the pan). It actually got me all the way back to the shop in limp mode which was about 25 miles, 10 of which on a logging road.

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 on 2nd fix), driver's seat belt and armrest broke, pass side also (wrty fixes). Also having wierd problem during cold months with intermittent dash light and guages recycling, no fix yet. Orig brakes are still strong at 90k miles, tire wear good, body still tight and quiet, engine strong with no oil usage

The experience of getting better gas
milage with the 6.0 motor in the GMC as
opposed to the 4.8 in my Chev, makes me
wish I had bought the Chev with the 6.o
instead of the 4.8. Factor in the
added pulling power, makes it far
better. I highly reccomend getting the
6.0 in either model truck.

Traded in my 96' GMC 3/4 ton Suburban, w/ 454
Vortec engine for this new crew cab, Duramax w/
Allison transmission. Wow what a difference in
towing power. Previously driving over mountins into
Prescott and Payson, from the Phoenix area, we
were lucky to keep up 35mph. Now, wow, 65mph
over the same roads and mountains, towing the
same trailer. Diesel milage is better than the gas by
about 5 to 6 mpg. Wish the Suburban had this
engine/trans.
