  GMC 2500 HD/ Durmax Diesel - 2004 GMC Sierra 2500HD
  By tabinmn - March 24 - 10:00 am

  I appreciate the diverse choices when purchasing vehicles but choose to pick GM d/t the ability to find anything from fast sports cars, Corvette, to tough Durmax Diesel. The current Vehicle of choice is as described above and I wouldnt tow w/out the performance of the GMC Sierra 2500 HD Durmax Diesel. Not only does the beautifully engineered design look great driving down the highway but also performs outstanding w/absolutely no problems. This is my 3rd Duramax and would recommend it to any serious driver that needs a truck w/towing capacity. Not to mention gas milege...what truck of this capacity can get

  This Truck needs help! - 2004 GMC Sierra 2500HD
  By Ron Sanders - July 30 - 5:13 am

  Truck rides very rough. Trucks 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. Thats why this truck has been in 3 fender benders. Had to replace complete rear brakes and rear seals .

  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. Ill go back to the Ford F-250 with the V-10. More power, better gas mileage and reliability.

  Research Before Buying - 2004 GMC Sierra 2500HD
  By Glenn - March 4 - 2:06 am

  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 GMs 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.

  Good but could be better! - 2004 GMC Sierra 2500HD
  By Jose Galvan - November 19 - 2:00 am

  Thus far its proven to be what was expected. I do like the pick up power and acceleration power, the turning radius needs to be inproved. Another plus would be to install a rear window that is fuctional. Heat controls for the rear needs installed. Overall the performance, handling, and appearance are what I expected. Ive named it the HULK, its big, its green and its powerful!
