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.

  OK so Far - 2004 GMC Sierra 1500
  By mgandrew - October 17 - 12:43 am

  Bought used 117,000. Used a little oil and coolant would need irregular replenishing, odd. Every now and then a sticky lifter, then when I added Lucas to the oil all H--l broke loose, literally. Next oil change there was so much sludge in the sump the oil would not drained. Long story short, the sludge clogged the oil pump suction and w/o oil pressure things were not going to get any better. Found a used motor (100,000) miles, swapped out. Better engine, more power, no oil consumption, coolant OK. Ill probably drive this truck for another couple of years. I like it. I think the sludge was related to the coolant loss. As it was infiltrating the crank case and slowly evaporating out?

  Love my Truck - 2004 GMC Sierra 1500
  By Cheryl - August 15 - 3:26 am

  The Sierra has a comfortable ride with tons of room in the front seat and also in the back. I like the short box. It was just enough for everything I was hauling and kept the vehicle length shorter. The 8 cyl give the Sierra great pick up. However the gas mileage is quite low. I have owned it for three years (48,000 miles) and have not had one problem with it.

  Mushy seat - 2004 GMC Sierra 1500
  By Bill Williams - September 22 - 5:20 pm

  Overall its a really good truck. The drivers seat is mushy and lacks support, both the bottom and back of seat. The fabric on the seats is poor quality and is pilling on all seating surfaces. It drives good, has adequate power, and is really quiet. I frequently pull a trailer and it has good towing ability.

  Update review - cold feet - 2004 GMC Sierra 1500
  By schodack bassman - July 19 - 9:36 am

  Overall I have been very happy with the truck. My feet get cold though from a draft. Couldnt figure out why until I noticed recently that the material over the fire while kind of melted away so the yellow insulation is now showing. May be why there is a draft in the cabin. Have almost 44K on truck and no major problems. Drive train noisy/clunky but very reliable. Only work is oil changes, just changed air filter, tighten emergency brake once a year and thats it. Next year might get a new one. MPG is not bad. For history of truck about 16.5. Around 18-19 on highway when keep 70 or under. Not bad. Truck still turns heads.

  Bad Experience! - 2004 GMC Sierra 1500
  By vargalu - July 17 - 10:00 am

  Nothing but problems with vehicle. Bad towing capability. Noisy (valve clatter) on cold mornings, sounds like a diesel. Transmision went out at 50000 miles. Front axle bearing went out at 20,000 miles. Enough problems. Im trading in for anything but a GM product!

  2004 GMC Sierra SLE 5.3 litre - 2004 GMC Sierra 1500
  By REber - June 4 - 3:30 am

  The truck is more care like than truck. The suspension is soft and bottoms under heavy load. Ive never attained the fuel economy declaired, only about 13 to 17 at best. Its been recalled once. The brakes have never been grippy enough. GM says the dashboard may go out at 70,000 miles and the stearing column center shaft went out twice. Now the left front wheel bearing is going out. The truck has not been abused!! I want to buy American but the quality needs to improve before that happens again! Most of the miles are highway miles with lite loads. The repairs have been very pricy. I purchased the truck new and there are only 39000 miles on it.

  Update - 2004 GMC Sierra 1500
  By schodack bassman - September 12 - 12:50 am

  Overall this has been a good vehicle. Nice looking truck with a nice ride. Xm radio a must and the 6 CD Bose music system is great. Only complaint is about drive train noise. Seems the locking differential kicks in often with a clank. Dealer says normal. Had minor problem with front end the dealer took care of quickly and without complaint. Over all good value. Will buy another some day.

  Whatta Truck! - 2004 GMC Sierra 1500
  By krakrjak - September 8 - 10:00 am

  Excellent truck. MUCH more than I expected. Good value, excellent craftsmanship. Fit and finish is up there with fine import automobiles costing $75,000+.
