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


Review

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 got 20 mpg)


Favorite Features

Roomy cab, comfortable seats, fine instrumentation. AWESOME diesel engine! Terrific mileage for a vehicle of this size and power. Lots of amenities.


Suggested Improvements

Would be nice to have more switched power outlets under the dash for accessories. (Have tested with power meter and only found one). Watch out on washboard roads - vehicle suspension will let you know immediately that it is a 3/4 ton. Only complaint - pricey!!!

Review

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


Favorite Features

Comfort, power, ride ok, luxury options, looks, towing power, ease of driving. GM trucks for me have proven to be good for long term purchases.


Suggested Improvements

GM should tighten up the quality control some more. Already the best, would only make them better.

Review

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.


Favorite Features

The Duramax engine, the cab room(front and rear), easy to work on, good mileage,the lighting(upgrade to a Bright Box)it is good stock though, handles great in all weather, the ride is great and the in cab storage is very well thought out.


Suggested Improvements

upgrades the tires to 33"(no lift required), upgrade the headlights with a Bright Box, aluminium skid plate are far better than the plastics(get some) and some step bars so you dont destroy the edges of the seats

Review

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.


Favorite Features

Heated seats, good power, OnStar.


Suggested Improvements

Steering! So bad, I will have to get out of the truck. Overall quality of the truck needs improvement. Improve rear seat room.
