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.

  Best vehicle I have ever owned! - 2005 GMC Sierra 1500
  By Jeff - April 16 - 12:23 pm

  I just bought this truck used and it looks like it just rolled off the factory line. I have owned 2 F-150s and 04 Dodge Ram Quad cab. This by far blows them away. I traded a BMW 525i for it and I actually enjoyed the ride home better. My kids love the factory RSE DVD player and the room in the backseat compared to the other trucks I have owned. I love the drivers seat with the 4 point lumbar support, dual heated and powered front seats and very soft leather front and back. I have always jumped from vehicle to vehicle but I think I have found what I was looking for - a vehicle that has all the comforts of a sports car and the convenience of a pick-up truck.

  Great towing vehicle, I love the trailer package with the lights and brakes already wired and the automatic slowdown feature on the gearshift. The on-demand rear differential lock is very helpful when driving on snow and ice. I recently hauled over 8000lbs on the truck and a double axle trailer from Ohio to Atlanta and was very pleased with the power response and vehicle handling.

  Needed work but worth it. - 2005 GMC Sierra 1500
  By murrayst45 - January 3 - 12:47 pm

  Bought this in fall of 2007 with 60 thousand miles. Pumped a lot more money into it than I thought I would have to, to start out. Wheel hub bearings on both sides. Tie Rod ends. Ball joints. Air conditioner blower motor. u joints. Overhauled front brakes and rotors. This was over a course over 60 thousand more miles I have pumped into it. 122k on it now. I really do like this truck though, I do not pull very much and I love the feel behind the wheel. If it was 4x4 it would be perfect, but its very dependable and hasnt ever broken down on me on the road. Im hoping to get several more miles out of it. Only problem now, the wheels never stay in balance or alignment and I never offroad it.

  I like the performance that it offers.This one is quieter than my 02 was and very much improved fit and finish on the interior.What I greatly dislike is the color choices especially for the interior.!!!!

  Truck was selected over the F150 feel the GMC was a better buy. Took it on an 800 mile trip and averaged 20 miles a gallon. Has plenty of power available when needed.

  Best truck I ever owned is a GM brand. - 2005 GMC Sierra 1500
  By AJs - March 3 - 7:20 pm

  I love the way the truck handles, and the way it has such good pick up when you are out on the road. You kick it in, and it will rock. The sound system is great. I love cruising down the road, rocking to whatever I choose. It is just a great machine to drive. I truly do love this GMC truck.

  Awesome truck - 2005 GMC Sierra 1500
  By zeek - February 26 - 11:53 pm

  Plenty of power from the v6 and great mileage too. With the 5-speed manual I get an average of 25mpg on the highway and 20 in the city. Not bad for a full sized truck.

  05 GMC SLT Crew Cab - 2005 GMC Sierra 1500
  By Bob - January 1 - 7:06 pm

  I am handicapped and this truck is very easy for me to operate. Everything is in clear reach, no need for any modifications. My wife, grand- daughter and I took a trip from Texas to Florida after buying the truck with no issues. Gas mileage is fantastic.

  2005 1500 GMC Extended Cab - 2005 GMC Sierra 1500
  By Orlean - November 17 - 7:40 pm

  Except for the early tranny issue and the noise coming from my steering column, this truck has been spectacular! Thanks to a personal mechanic who was a GM mechanic, the steering column has become a non-issue. And, the dealership took GREAT care of the tranny issue. 140,000 miles into it and I STILL love this truck! Ive driven it to/from CA and TX several times, in both winter and summer, and its served me VERY well! MPG has deteriorated over the years, but thats to be expected. Started at 17MPG and now at 15! I miss that extra 2MPG!
