Overview & Reviews

For 2006, there's a new "VortecMAX" performance group that includes a 345-hp 6.0-liter V8, a heavy-duty tow package and a stronger rear axle; thusly equipped, the half-ton Sierra is on more equal footing with Nissan's Titan and the Hemi-equipped Dodge Ram. The Quadrasteer four-wheel steering option has been dropped, and the optional camper-style mirrors have been replaced by a folding and extending design with a built-in convex spotter glass. Other changes on the GMC truck include slightly updated front-end styling and minor adjustments to trim levels and body configurations.

• Roomy extended and crew cab models, variety of V8 engine options, innovative features, slick hybrid-electric option.

• Lags behind the competition in refinement, spotty fit and finish, low-grade interior materials.

  Great Truck - 2006 GMC Sierra 1500
  By P.S. - Texas - December 27 - 6:13 pm

  I purchased this truck on a whim and it has been the best thing I have ever done. The truck is fantastic, it meets all my expectations and more. It is an absolute pleasure to drive around town or on long trips. I would certainly continue to by GMC in the future.

  My First GMC Truck - 2006 GMC Sierra 1500
  By roadturtle - October 5 - 12:03 pm

  I have owned Toyota, Nissan, Chevrolet, and Ford trucks. I chose this GMC truck because I could reach into the bed without having to climb into the truck bed as you have to on Fords. I wanted the full four doors, a small, but powerful V-8 5.3 L. It get equal gas mileage to a Nissan Frontier yet I get a real full size truck for the same price. The seats are very comfortable. I can get into the cab of the truck without stepping onto steps, or hitting my head because the door opening is small as on the Toyotas. It turns sharp, rides nice, handles well, and it came with dual climate zones. My wife loves that. Its the little things that also count such as, fuel filler on drivers side, fog lamps

  GMC Trucks are Junks! - 2006 GMC Sierra 1500
  By Mark Dandeneau - September 10 - 12:26 am

  I was a die hard GM fan until I bought this 2006 truck. Ive talked to other owners of GMC and Chevy trucks and if they had it over again then would have never bought these trucks, in fact we all want to unload them because of the clunking noise and vibration when the transmission shifts. Also these trucks have problems with wheel bearing hubs and steering problems as well as u-joint going. The next vehicle I get will be a Toyota

  Joy to own, my first GMC truck - 2006 GMC Sierra 1500
  By JosefM - July 19 - 2:13 am

  Ive owned this truck for only a month, but it is a welcome surprise. Power and ride is far better than expected. Gas mileage is better than most, in this vehicle class. Towing and hauling is impressive. Ive carried a couple loads of wood through rough terrain (4Low works well) with ease! Would recommend to anyone wanting a powerful and functional truck to buy one today.

  knocking noise and wires - 2006 GMC Sierra 1500
  By primetime - April 26 - 6:13 pm

  within the last year since I hd my sierra around 48,000 miles as I began to accelerate after I had been at a light or stop sign I am been getting a knock or a clunk as if the u joint is bad. also when I took it in for service because the engine light at 35000 miles Dealership told me it was rodent damages. This is an excuse after talking to other sierra owners it was just faulty wires that GM put on trucks. I wont buy another, after 3chevys and a gmc I am going to ford.

  Great Truck!! - 2006 GMC Sierra 1500
  By Mike C. - April 21 - 3:16 pm

  My 1st GMC Truck. I test drove a Dodge, Ford, and Silverado. This truck runs excellent. Rides nice, Lots of room and it is fun to drive. Towing is exceptional, I have hauled 1/2 ton of sand with no problem. Gas mileage is good for as heavy as the vehicle is. Clear view of all vehicle traffic while driving on to all intersections and from yield signs.

  Confused by others - 2006 GMC Sierra 1500
  By T.Davis - October 27 - 3:53 am

  I have owned toyotas and nissans and never get the mpg they or the reviews say. 2 to 3 miles less. With GMs I have seemed to get 3 to 5 miles better than reviews. Thats why I say confused by others. Just got 22.6 combination downtown Nashville, TN interstate,country roads. Just bought this truck and probably will keep it for a long time. Guess my driving habits suit GM products better. This truck has 5.3, 323 gears,2wd, locking rearend and HD towing.Confort scored 8 cause stiff HD suspension (I guess). Build quality an 8 cause of interior parts a little weak. Reliability was 9 mainly cause of my past history with GMs. Havent owned this one long enough to tell. Thats my 2 cents worth.

  Functional but boring - 2006 GMC Sierra 1500
  By Keith - July 12 - 9:53 am

  I drive this vehicle for business, and typically turn a vehicle over every two years after putting on about 100,000 miles of gravel, off road and hwy driving. Past truck was 05 F150. I picked the GMC for its gas mileage which is quite good for a full sized truck, definitely better than my experiance with Ford and Dodge. Unfortunately this is the only area where the GMC exceeds the other American brands. I found the GMC has a lot more interior noise at hwy speeds than the new model F150. The GMC trailer towing capacity is clearly less than the F150, cant really put the GMC in cruise as it will rev so high. On uneven roads the GMC has so much body flex, it creaks like a covered wagon.

  Best truck Ive ever owned - 2006 GMC Sierra 1500
  By rick spriggs - June 10 - 2:33 pm

  It has 4 wheel steering and it is great when im towing my trailers or I need to park in a tight spot. The truck has all the power I need and it gets about 18-19 mpg, 16 mpg when towing. The seats are like sitting in a lazyboy, very comfortable. I love my truck.

  Sorry to say my last GM product - 2006 GMC Sierra 1500
  By GDBYGM - April 21 - 1:20 pm

  Like others my truck ran flawless for the first 15,000 or so and then the problems began. The rear drum brakes started to squeal every time you applied them, dash rattle, headliner rattle(dealer attempted to fix-rattle is back). Approximately 20k turning the steering wheel produced a weird noise(dealer tried to repair-its back) 26k new front rotors and pads(my other vehicle has 71k with original pads if your wondering about my driving). 37k new belt tensioner and belts(squealing noise) 39k main engine seal leak(luckily repaired by GM) 41k steering link rattle(replaced link) and now "service brake system" message displayed. Thank you for stealing my $34,000 GM
