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.

  Dead Reliable - 2005 GMC Sierra 1500
  By Dennis - September 13 - 1:50 pm

  This is my 4th new GMC full size. They are more reliable than the 3 new Mercedes automobiles I have also owned. Comfortable seats...easy highway cruiser. The 6000 engine is great, but loves gas!

  Nice Ride - 2005 GMC Sierra 1500
  By Truck - June 11 - 1:56 am

  I considered the Tundra and new F150 and am very happy with my choice. It is powerful enough to easily pull my 20 powerboat and the ride is like a big, roomy luxury car. I like that I can select the automatic 4WD mode and forget about it on dry pavement without hurting anything. Unlike on the Tundra, the back seat of my extended cab version is actually usable for adults.

  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.

  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.

  GMC Sierra - 2005 GMC Sierra 1500
  By Jerry Wright - February 25 - 7:20 am

  This is my 1st crew cab, Ive owned quite a few extended cabs in both GMC and Chevy. I believe this truck is the best handling of all the trucks Ive owned. This has a 5.3 V-8 which is what I needed to pull my boat. It is a SLE model which has cloth seats, which I like better than leather. The seating is very nice and comfortable for large people and small alike. I would highly recommend this truck.

  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..

  05 GMC EXT CAB SLT Z-71 - 2005 GMC Sierra 1500
  By Lee - October 14 - 12:33 pm

  I purchased this certified used truck with 52,000 on it the black exterior and gray leather were spotless and everything works as new from heated seats, xm radio, on star etc. I have added a lot of aftermarket chrome parts and a dual cat back system, K&N intake and Hyperteck programmer. Ive been thinking of brighter headlights Silverstone, and itll be a keeper with the 100,000 mile extended warranty the 5.3 is working just fine so far and next oil change will be Mobil 1 at 5000 mile interval will report problems when they start so far so good.

  Great Truck - 2005 GMC Sierra 1500
  By Montanatruck - January 19 - 10:13 pm

  This Truck is amazing. It has great acceleration, and power. I drove from Los Angeles to Bozeman, Montana in 2 days, around 1400 miles, and it didnt even have a hiccup and hadnt lost any oil. We had a snow storm the other day and truck drove like it was on dry pavement. When I was shopping for a new truck I was looking for a truck with plenty of torque, so the japanesse trucks were no in question. I had to decide wheather to choose ford or GM, but i eventually decided on the GMC because I liked the style, and had everything I wanted.

  Gmc crew cab - 2005 GMC Sierra 1500
  By Bill - November 11 - 1:46 am

  Mileage has been above what I expected for a vehicle of this size. Very comfortable on the road. Handles very well on trips and the 5300 has plenty of reserve power
