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.

  I switched from a Ford F150 to my GMC, and I love the GMC. I do wish the bed was longer.

  Denali Hauls! - 2005 GMC Sierra 1500
  By Black Magic - June 13 - 5:06 pm

  I have driven about 2200 miles in the first month. Half of the miles are towing a 5,500 lb. ski/wakeboard boat. This truck is incredible for towing. The AWD never spins on the ramp or backing up my 13% driveway with the boat. Loaded, the ride is excellent. Unloaded, it is a little choppy compared to my previous Yukon Denali XL. But, hey its a truck. Mileage is better than my 01 DXL at 14mpg average. Again, its a 345HP truck, its for hauling. Great truck. Unloaded, this thing is fast for a truck and fun to drive. No problems so far.

  The Truck - 2005 GMC Sierra 1500
  By MARK GUERNSEY - February 14 - 10:00 am

  This is our third GMC extended cab z71 we had a 99 a 02 now a 04 which we see a improvements such as the duel climate control, the bose sound system with the xm radio is fantastic, the 02 pickups speakers blew out with in a year.. much higher quality sounds.. the previous two pick ups with in a year the rear windows leaked air. making riding almost unbearable... which would be my two main complaints. which the 04 appears to be a much better truck. I wont go with the extended cabl on my next one i will go with the four door. but love the GMC product line, and will keep buying the yukons, and pickups. Mark G. of Niles Michigan

  Greta truck - 2005 GMC Sierra 1500
  By Alan - February 5 - 10:30 pm

  This has been a great truck. One person wrote that his wouldnt tow, but he had the 6 cylinder. Why someone would not buy a V8 for towing is beyond me. My 5.3 has been flawless and I often tow a boat, motor, and trailer weighing 7000 lb and the G38 locking differential has allowed me to get up any boat ramp. I added a K&N cold air intake and Gibson cat back exhaust and get 22 MPG on the interstate and and 28 at 55 MPH.

  My Truck - 2005 GMC Sierra 1500
  By jjdward - August 28 - 7:56 pm

  I love my GMC. It has plenty of room, power, and comfort. I love the 5300 rumble when you get on it, but I learned quickly not to get on it to much, gas is not cheap. To be a full size truck with this power, the gas mileage is good.

  2005 GMC crewcab - 2005 GMC Sierra 1500
  By Bills 2005 - July 25 - 3:43 pm

  I consider the truck an outstanding buy with the rebates and other incentives that were offered. This is my 4th GM truck and it is the best one yet. The gas mileage is great for a truck of this size. It averages over 18 mpg in my daily driving, and 21 on the road.

  My GMC Truck - 2005 GMC Sierra 1500
  By Don Sharlow - July 11 - 7:36 pm

  My GMC truck is very reliable. The body integrity, motor and drive train have given me nothing but good service. I drive it to work every day, which is about 120 mile round trip, and find it comfortable and safe to handle and control in heavy traffic. Too bad you dont have one too.
