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.

  Cracked Cylinder Heads - 2004 GMC Sierra 1500
  By formergmcguy - May 7 - 10:58 am

  At about 53,900 miles, my 2004 5.3L developed a ticking noise. Turned out to be cracked cylinder heads. $3800 repair bill. I had it repaired and traded it for a brand new Tundra with 5.7L engine. No regrets.

  Love my GMC - 2004 GMC Sierra 1500
  By Mac - October 11 - 9:46 pm

  I purchased my Sierra new, now have 49000 miles. Have had a couple problems but the dealer took prompt, and courtious care of my truck. Fun to drive, looks great gas mileage isnt bad either. I keep the oil changed, and just installed a K&N air filter and will see if my MPG improves. Overall I would buy another one.

  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!

  The Best - 2004 GMC Sierra 1500
  By MoniqueC - June 11 - 10:00 am

  Working for GM I am able to drive quite a few diffrent vehicles. This is definately my favorite one so far. I love this truck. The performance on and off road are number one. If your looking to purchase a new truck give this one a chance to win you over. It did me.

  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.

  2004 GMC Sierra 1500 SLE 4X4 Std cab SB 5.3 - 2004 GMC Sierra 1500
  By p145897 - May 22 - 12:08 am

  Just turned 100k. Even though this truck has been meticulously maintained and never abused, it has had the transmission replaced (at 67K), sound system (at 25K), intermediate steering shaft (3 times), HVAC controls (at 75K), front rotors (2 times), instrument panel (at 70K), steering wheel control modules replaced (80K), etc. There is so much slop in the drive train that I would never consider using as a tow vehicle. Good for going to the dump and grocery shopping. Limited slip (rear) is demonstrating signs of impending failure, just a matter of time.

  GMC Kicks Butt - 2004 GMC Sierra 1500
  By BobbyL - August 25 - 5:40 pm

  This is a great truck for work or pleasure. it hauls heavy loads and trailers with ease, yet when unloaded it gets around like a sports car. very quick and little slip when taking off. Brakes way better than any Ford Ive ever driven. Truck has all desired features including power windows/door locks. Stereo has no rattles at full volume. I get a lot of positive comments... Nice truck
