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

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?

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

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.

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

I am pleased with my purchase at this time. It tows as is expected for a truck with its power- it is capable in the woods and farm as well as on the highway-- though the fuel economy is a jolt. But then again it is alot of weight to move.

During the first 3 months my truck was in the shop 6 times. Radio would not return CD, without it for 3 days. Once for extending camper mirrors, passenger side motor bad. Once for A/C, recall part not replaced prior to purchase. Three times for 4 WD, computer chip keeps going out and shifting into 4WD low on its own regardless of speed. I'll go back to the Ford F-250 with the V-10. More power, better gas mileage and reliability.

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?...
