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.

  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.

  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.

  Its a good one - 2005 GMC Sierra 1500
  By ibuyalot - September 14 - 1:56 am

  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.!!!!

  Weak drive train - 2005 GMC Sierra 1500
  By Hwy363 - March 19 - 10:00 am

  Not a bad truck until the warranty was up. Before then, the only thing to go wrong was the rear door latch adjustment. It worked well in winter (western Canada), got great highway mileage and was reasonably comfortable. For the past two years the following have gone wrong: transmission replaced at 65K, 4WD position sensor replaced three times, tie rods twice, front hubs once. My mileage is 4/5 highway / 1/5 gravel. Its never been driven hard and has had very little mountain driving. Fit and finish are not great but not bad either. Accessories still all work. I bought the truck after having an Olds Alero and Saturn Ion (both had serious drive train issues). I wont buy anything from GM again.

  Fine Truck - 2005 GMC Sierra 1500
  By Myran - March 4 - 5:50 am

  I love getting into my GMC. It is well built. It is comfortable to the people in the back seat, and it is nicely appointed.

  Good truck!! - 2005 GMC Sierra 1500
  By steve b - February 13 - 9:20 pm

  I bought this truck after driving the Ford, Dodge and Chevy. I had a trade and the dealer offered me the best deal. The P rated tires that came standard with the Z-71 package were junk, so I spent a few more bucks and got the same size 17" BFGs. That dropped the mileage from 22-23-to 18-20 depending on speed but the reliability is much better. The auto transmission does seem weird at times but the all aluminum block V8 with the higher H/P is just fantastic.Overall the trans is good. I tow a light weight camp trailer and I forget its behind me. No problems so far. 12,000 miles through all kinds of weather. For the money, best truck I ever owned and I have had a few. Good looking truck..

  Bad experience - 2005 GMC Sierra 1500
  By Frank Leslie - July 24 - 3:13 pm

  Intermediate steering shaft made noises, steering rack had to be replaced. A/C will not work on inside air setting. Other than this, the vehicle is pretty good.

  Best Truck For the Money - 2005 GMC Sierra 1500
  By Marc B - July 21 - 2:50 pm

  I read all the reviews on this truck before I bought. And most of them were positive. So I went out and bought used from a trustworthy dealer. Drove home over 400 miles that afternoon and night and totally enjoyed the ride home. Truck is very nice ride, and good looking. 5.3 engine has it all also. Gmc is easy to work on, and do your own services on. Save money right there.

  2005 hd review - 2005 GMC Sierra 1500
  By Roger - February 5 - 6:23 pm

  Great truck, has served well in snowy to over 100 temps. Have hauled trailers and 10000 pounds of hay with no problems, using t/h switch is very good as it lowers tranny temp. 53 k miles with 0 problems. avergage mileage is 13.2. Not bad for a 9600 GVW rating with 410 axle. Hauls 3000 pounds of block in bed with no problems.
