  Fuel mileage is poor at best. Engine surge and hesitation. Driveability is very eratic. Vehicle runs hot, fan runs excessively. Tranny and engine temp gauges always show 210 or better. All this while running vehicle empty. When towing all of the above is off the charts. GM answer is that all is normal.

  05 GMC 2500HD Duramax/ZF-6 Manual - 2005 GMC Sierra 2500HD

  I enjoy this truck. The diesel has a lot of pep. The manual trans. is nice after getting a feel for it. The build quality for my W/T is less than desired. Handling is excellent for a truck this size. Ride is smooth. It has some design faults (ex: windshield wipers rise only about 3" from glass, pain to work on) and penny pinching faults (ex: no sun tint on top of windshield). All in all, I recommend.

  Great Truck - 2005 GMC Sierra 2500HD
  By Keith - April 4 - 6:23 am

  I drove them all. GMC still offers the work truck and although it might be too spartan for some, I found it to be the right balance of form and function. Also, if price is an object (isnt it always)this baby rocks. I use my trucks like, well, trucks. And if I had had to spend $40,000+ on something else, I might be guilty of babying my truck. Then why by a truck? I had a bedliner sprayed in, and now it sees full duty as my primary working, boat pulling, camping, wheeling vehicle. Fit and finish are very nice. Plenty of power with the 6.0L. Even the cloth bench seats are comfy.

  Not Enough Professional Grade - 2005 GMC Sierra 2500HD
  By Ken - April 1 - 10:33 am

  Three days after purchase the truck was in the shop with transmission problems. It was there for four days leaving me without a business truck. I now have to take it back because the transmission is causing more problems. There is a thumping noise behind the dash that I cant locate. The ride is fine for a heavy duty truck. I really expected more from GMC. The seats are too narrow and Im a short person. I traded in a 2000 Yukon. I will be looking at the 2007 Tundra next year.
