Review of the 2004 GMC Sierra 2500HD

  • 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.

  • Safety
  • Pros

    Powerful drivetrains, roomy interior, numerous available amenities.

  • Cons

    Spotty build quality, cheap interior materials.

  • What's New for 2004

    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.

Duramax powered

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

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.

Vehicle: 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 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

This truck needs help!

Vehicle: 2004 GMC Sierra 2500HD 2dr Regular Cab Work Truck 4WD LB (6.0L 8cyl 5M)

Truck rides very rough. Truck's brakes are sluggish. Truck is 6 litre not great gas. Truck has had all kind of problems! If you have to stop fast you are in trouble. That's why this truck has been in 3 fender benders. Had to replace complete rear brakes and rear seals .




It was nice at $1.89/gal

Vehicle: 2004 GMC Sierra 2500HD 4dr Extended Cab 4WD LB (6.0L 8cyl 4A)

This truck has been used mostly on the highway, carries dirt/mulch and recreational toys. And has done so for 62,000 miles without a single mechanical problem! It was originally purchased for towing a camper. Within 6 months of purchase, rising gas prices made driving this thirsty vehicle downright painful! With the cruise control set at 65 station to station on an interstate,13.7mpg. Disappointments? The ventialtion system. The AC is not cold nor dry enough to defog windows. And the radio is horrible! Did I mention fuel efficiency?




Research before buying

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

The quality of this truck is questionable. Major issues include getting only 275 - 300 miles/tank of gas. Serious steering problems with absolutely no long-term fixes. This is a widespread issue which truly makes the truck a misery to drive! Rust at less than two years. Faulty air, seating, and other minor repairs. I can hardly imagine buying another due to GM's lack of being able to warrany their trucks and offering a fix on such a major steering issue. All they offer is a lube which needs to be applied every four to six months and does not really work well.

I cannot get the front axles to engage, I have replaced the front actuator, and the 4W/D indicator lamp switch which did not help. My next step is to look for a broken wire in the harness going back?...
