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.

  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.

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

  Very Satisfied - 2005 GMC Sierra 1500
  By Pat Patterson - June 1 - 7:20 pm

  No major complaints. Overall a very well balanced truck. Roomy, comfortable, decent gas mileage. Recently traded for a 2008 model because of the rebates and incentives but if not for that this wouldve been a keeper.

  2nd GM truck - 2005 GMC Sierra 1500
  By Jonathan - January 29 - 4:06 am

  I started with a 99 Chevy Z71 that I drove 200k miles and beyond its last leg so I traded it in for this GMC Crew 2WD with the 5.3 L. I was disappointed with the extended travel in the front suspension and huge turn radius. Its great on long trips for comfort, but gas mileage averages around 14 in the city and 16 on the highway. It feels real solid until you tow ANYTHING more than 500 #s, it struggles over 55 mph with shifting a lot, due to lack of torque. The steering pops and clunks like my 99 did, the same for the rear-end chirp on start/stops. Bad design still being used from 99, thats just annoying. I like the comfort and prefer cloth over leather on long trips and in hot Texas.

  My 5th and last GMC - 2005 GMC Sierra 1500
  By yellowdog - August 10 - 12:16 pm

  Air conditioner took three dealer visits to repair. Drive train problems have been present in this truck since the first 700 miles. Lack of towing power and loud whining noise has been present when towing a small boat. And to top it all off, the service manager at the dealership refuses to give me a necessary third visit so I can file a Lemon Law complaint. I have had 5 full size GMC(all from the same dealer) and this one will be my last.

  watch out - 2005 GMC Sierra 1500
  By bill - June 7 - 8:20 pm

  the defective casteck heads in my 5.3 leak coolant. this causes what sounds like bad lifter. know what heads are in your 5.3 before you buy, otherwise you could wind up with truck with repairs more than its value.
