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 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.

  Truck has exellent performance with the 5300 engine. The gas mileage we averaged on an 800 mile trip was 20 miles per gallon which I thought was exellent for a truck of this size. It has plenty of legroom room in the back seats. I considered an F150, but after comparing the two I went with the GMC

  This truck you can take to the opera! - 2005 GMC Sierra 1500
  By lastchanceblogger - February 18 - 5:30 pm

  Amazing truck. It has outstanding acceleration, and the SLT package with OnStar makes it feel like a Cadillac, not a truck. This truck serves two purposes: you can haul drywall, and you can go to the country club.

  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.

  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.

  I have owned lots of heavy duty GMC trucks with gas engines (5.7liter and now 5.3liter) for many years for myself and for my business. We very seldom have had any major breakdowns with these vehicles other than wearing them out after several hundred thousand miles have been first put on the trucks. Many times we just overhaul the truck and put it back in service. They have always been very reliable vehicles for our business and personal use. We recently purchased 3 light duty Canyon trucks with the 5 cylinder engines and so far with over 100,000 accumulated miles they have also been trouble free and are also providing great gas mileage!

  Great Truck. - 2005 GMC Sierra 1500
  By Golf26guy` - December 18 - 10:30 pm

  Very comfortable truck. Im a sales manager and I drive over 45k miles a year. Seats are great, good gas mileage for a fullsize V 8 truck. I recently made a trip from Atlanta to Houston pulling a small trailer with a 4 wheeler in it, did not meet my expectations for pulling, keeps downshifting.

  Velvet glove, Iron Fist - 2005 GMC Sierra 1500
  By Ray - November 13 - 1:20 pm

  This truck is the ultimate Great American Vehicle, a fast, powerful and exquisitely beautiful truck. I grew up in the seventies, and loved cars. This truck is quicker than Vettes of that era, with a ride equal to that of luxury cars of today. With its Z-71 suspension system this monsterous beast can cut around corners like a sports car, not bad for being able to tow 4 Mazda Miatas down the road without breaking a sweat. Gas mileage can stink, but this truck also comes with a sophisticated Driver Information System, one of its abilites is giving instantaneous fuel mileage. Steady 60 MPH kicks back 24.9 mph. That is phenomenal! Gunning the rumbling 5.3 motor is addicting however! I LOVE IT!

  I wish I bought a Dodge - 2005 GMC Sierra 1500
  By joe - September 13 - 8:20 am

  Was a decent truck when I bought it. But it wouldnt tow worth a dang, piston slap, horrible trans, creaks, squeaks, parts breaking, clunking from steering shaft, burnout lights, sound system, tires, brakes, and so much more wrong with it. My 2nd gm and last. Im buying a Dodge.
