Overview & Reviews

Quadrasteer is no longer available on 2WD models, standard wheel sizes have been bumped up to 17 inches and, on extended and crew cab models, a power sunroof that includes HomeLink and a deluxe overhead console in now optional. GMC takes a step backward this year with the return of rear drum brakes, as opposed to last year's four-wheel disc setup. Big changes for the Denali this year -- Quadrasteer is no longer available, and the Denali is now a crew cab model only. A gasoline/electric hybrid model is also introduced this year. Basically a "mild" hybrid, the system provides no power boost, but does allow for automatic engine startup and shutdown at stops. This truck also comes with four 120-volt AC power outlets and is the only Silverado with rear disc brakes this year. The hybrid truck is only available in Western states and Florida.

• Roomy extended and crew cab models, strong V8 engines, innovative features, slick hybrid electric option.

• Lags the competition in terms or refinement and power, spotty fit and finish, low-grade interior materials.

  One Sweet truck ! - 2005 GMC Sierra 1500
  By Patrick Carney - September 26 - 5:20 am

  I love this truck. I use this as an all around truck, and it is perfect for a medium weight trailer. I towed a Kubota back hoe, front end loader on a heavy duty twin axle rental trailer, and you could feel the weight kick you around. My buddy owns the same truck, and he installed air bags in the rear suspension and it greatly improved the trailer handling. Most of my driving is city mileage and short trips. Mileage is 14.2mpg for cit driving. On a long trip, with no added weight, I averaged 23.5 to 24 Mpg at 70 mph. I wasnt really impressed with its take off or low end torque, but I have to say that unloaded its power is deceiving. Its so smooth in its power delivery, but watch the speedo rocket .

  Crew cab 4X4 - 2005 GMC Sierra 1500
  By Wesley Willits - April 17 - 2:16 am

  I love the truck, but I have had it in the shop many times within the first couple months of owning it. I had to replace the radio, because it kept shutting off. I had to replace the shift cable, because the transmition was slipping. There have also been problems with the front passenger shock, dash, and bed squeeking. Along with wind noise from the front windshield. I have also noticed less fuel economy than my previous 5.3 from 17mpg to 15mpg, and a loss in low-mid range power (not towing).

  Great Ride - 2005 GMC Sierra 1500
  By Jerry - March 4 - 4:36 am

  Mine is a two door sportside with the small V8. The truck handles great, and corners like a sports car. Its a fun vehicle to drive. I have a black truck with a tan interior and I had to go to Arkansas from Texas to get that combination. There were only three in the country that had the combination I wanted. If you are looking for a good looking and fun truck, look at the GMC Sierra.

  2005 GMC Sierra - 2005 GMC Sierra 1500
  By ALLEN AIKENS JR. - February 26 - 5:36 am

  I love this truck. The quality, reliability. A very comfortable truck to drive. Also my 9yr old daughter loves the back seat. This truck has great power. The Chevy and the GMC are very close but the front end of the GMC just blows me away, I love the front end. One negative, the gas mileage is around 13 mpg, but I still have my 92 Chevy S-10 2 to offset the low gas mileage

  Not quite professional grade - 2005 GMC Sierra 1500
  By Brian - February 19 - 6:46 am

  Doors/cab seals are too tight, shouldnt have to slam the door. Only 18 mpg, not the 20 as the window sticker says. I get better gas mileage from my 98 Suburban. Knock in the steering. AC vent door noise. Front windshield not sealed correctly. Cheap radio and even cheaper speakers sound terrible. Very uncomfortable driver seat- No adjustments. Fuse box in the way of your left foot. Very disappointed in the engineering and material quality. Very little thought went into designing this truck, only profit. The whole truck is fake, proven by the fake chrome rims. I bought this truck planning to keep it 10+ years, now I cant wait to get rid of it, ASAP.

  Great Truck! - 2005 GMC Sierra 1500
  By Jeb - October 24 - 4:20 am

  Ive been satisfied with the truck so far. Its a bit under powered, but thats expected with 6 cylinders. Enough power if you dont tow anything. My only disappointments have been with interior design. There arent enough useable storage bins. Pencils constantly fall out of the ones on the dash board. The cup holders are in a strange and unhandy place. They make the middle seat useless. There is no storage space under the seats. Seats are very comfortable on long trips. Interior and exterior fit and finish are very good. No rattles. Gas mileage could be better.

  Didnt Like The Bowtie - 2005 GMC Sierra 1500
  By Ken - September 16 - 9:33 pm

  As a dyed in the wool "Bowtie" guy, it was tough to buy another type of vehicle. However, I cant stand the front end on the Chevy, so I went with the GMC. After 3K miles, Ive come to enjoy the truck quite a bit, but would like to see a few mods. Most are listed below, but I ran outta room for one - when negotiating a slight turn at fwy. speeds, any moderate imperfection in the road surface will cause momentary instability. This seems to be in the rack & pinion equipped models only, as my 02 Suburban with conventional steering seems significantly smoother over the same road surface. Overall though, Im really happy with the truck.

  My first truck - 2005 GMC Sierra 1500
  By kevin - April 27 - 5:00 pm

  Not a true hybrid, around 17.5 mpg. Great power. Handles well and I fit nicely inside- I am 6 foot 9. Nice Bose speaker system too. I easily adjusted to the engine that turns off at stops (a slight delay between brake release and engine power for acceleration)

  No More GM 4 me - 2005 GMC Sierra 1500
  By LostFaithGM - April 25 - 7:33 am

  Bought truck new and totally disappointed. Truck now has over 104k miles and here is list of repair. Passenger hub replaced under warranty and driver hub replaced at 76k. Trans rebuild 75k. Torque converter replaced @ 83k. Power steering has been terrible since 30k. Front diff passenger seal leaks since under warranty and driver front diff seal leaked at 101k. Now water pump gasket leak @ 103k. U-joint at T-case & drive shaft replaced at 86k. Interior makes noises and this is considered normal. Noisy cab when cruising at over 45 miles. Rust is everywhere on the chassis. My last GM light duty truck
