Overview & Reviews

The big news for 2004 is the addition of an all-new light-duty 1500 Crew cab model with a five-and-a-half-foot bed that replaces last year's 1500HD model. The Work truck package is now available on all Sierras, while base models get standard cruise control along with a chrome grille, wheels and bumper. Other changes include newly designed 17-inch wheels on 4WD models, the deletion of the Professional package and a Quadrasteer package that is now available without additional trailering equipment.

• Roomy extended- and crew cab models, strong V8 engines, innovative features.

• Spotty fit and finish, low-grade interior materials.

  04 much better than 99 - 2004 GMC Sierra 1500
  By GaDawg - August 23 - 2:23 pm

  I purchased a 2004 Sierra after buying a new 1999 one which was a DOG. I went against my better judgement and ordered the 99 knowing that GM never gets a new model right in the first year but I also know that after building the same truck for 5 years GM gets the bugs out, I was right, the 04 is much better than the 99 otherwise I would have shot myself by now

  GMC Sierra Sharp and Long Lasting - 2004 GMC Sierra 1500
  By Jerry - August 1 - 8:50 pm

  I have this truck four years now and not one problem. Mine is a sport side in black with added chrome. It looks and rides great. Instead of a heavy duty package, I have the easy ride suspension. It handles and feels great. On the open road it rides like a luxury car.

  Amazing GMC Truck - 2004 GMC Sierra 1500
  By Darren - June 8 - 7:13 pm

  Everything about this truck is amazing, from the way it drives, to all of its abilities, towing, hauling, etc. The most impressive thing is the Autotrac 4WD system, I have off roaded with it in the snow, and never slipped a tire, even in over a foot of snow!

  Pleasantly surprised - 2004 GMC Sierra 1500
  By rooddoggie - April 29 - 4:43 am

  I bought my 04 SLE extended cab 2WD last month and this truck gives me so much for my money. It accelerates effortlessly with the 5.3, shifts smoothly with the AT, and get 22 mpg on the freeway... thats right, 22 MPG!

  1978 Revisited - 2004 GMC Sierra 1500
  By Clayton - December 28 - 11:53 pm

  I like my truck. It is a "Plain Jane" truck-no options. Performance is better than expected, though the mileage in town is poor-about 15 mpg. Good ride and no complaints, though I have only 2500 miles on it. For being a base truck, it suits my needs and makes me wish reviewers would talk about the basic trucks as well as the duded-up ones. The reset on the oil change system is neat. I like the magnatized drain plug too. Very easy oil change. A great ride. Much better than my 1993 ford F-150. Very similar to my old 1978 Silverado but with a much better turning radius. The 6 cylinder has plenty of power for what I need.

  Cracked cylinder heads - 2004 GMC Sierra 1500
  By shane l - December 21 - 10:00 am

  I love the truck it is very comfortable, and has been trouble free for 5 years, till I noticed the coolant level dropping, I figured out it had cracked cylinder heads. Took it to Boulevard GMC in Signal Hill and they charged me $170.00 for something I already knew and lied and said they took the valve covers off to inspect, when it shows no one has taken the valve cover off, (BEWARE OF THIS DEALERSHIP) GM wont help pretty much had to fix my self. I put in Bars head gasket fix and the leak in the heads went away, been 3,000 miles all I have to do is change my lifters and push-rods and should be good to go. Dont think I am going to be buying GM anymore.

  Good ride - 2004 GMC Sierra 1500
  By Dave - December 4 - 11:30 am

  This truck has been very good to me. It has performed flawlessly and the gas mileage hasnt changed either up or down by more than 1 mpg. I thouroughly enjoy driving this truck. My truck has the Z71 package and it has a solid feel to it.
