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 The Quadrasteer four-wheel steering option has been dropped, and the optional camper-style mirrors have been replaced by a folding and extending design with a built-in convex spotter glass.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.

  First GMC Truck - 2006 GMC Sierra 1500
  By Dr. Joseph White - October 23 - 1:16 pm

  1st GMC truck that I have ever owned. I have always been a FORD man until two weeks ago. This GMC leaves all the FORD trucks I have ever owned in the dust. I love everything about my new GMC truck, especially the ride and POWERRRRRR. This truck is like riding in a luxury car with a sports car engine.

  No problems yet. - 2006 GMC Sierra 1500
  By koryharper - June 24 - 6:56 pm

  I bought this truck with 6000 miles on it. Its first drive was from Cleveland to Fayetteville, NC. Never really noticed anything expect it lacks in acceleration. It feels like 2nd gear when taking off. When downshifting it seems to rev a little too high. other that great truck, the only problem Ive had was at about 30k I got a ENGINE POWER REDUCED light but it went away when I came out of the bar. Brakes pulse a little too. But nothing major yet. I dont know why everyone else complains. "fingers crossed" If i ever switch brands itll be because this truck does lack in the power department. Once going its awesome but not great on the low end. However 4x4 is great in tough terrain.

  Wonderful truck - 2006 GMC Sierra 1500
  By ericfromhouston - April 10 - 12:53 am

  This truck has been great. The room is fantastic and the ride is a dream. My wife loves the way she can drive this truck and not feel intimidated. I love the power and the feel of the way the truck handles in all situations. GMC has defined the term "Texas - Cadillac."

  Nice Rig - 2006 GMC Sierra 1500
  By Robo M. - January 10 - 7:53 am

  Truck is very smooth. My wife has never driven one of my trucks by choice, but she wants to drive this one.I have owned Ford, Dodge. This is my first Z-71 Sierra. All the toys included except for a universal garage door opener. The engine is powerful and fast. Smooth acceleration fools you as to you actual speed. The MPG is approximately 3 miles per gallon more than my 2001 dodge truck. I live in hilly areas and the 4X4 truck averages 15 MPG. With 2 growing boys the Crew Cab gives them more than enough room in the back seat, grown adults no longer mind riding in the back seat of my truck. This is a cant miss vehicle! If you are looking for a new truck test drive this one!!

  Poor Quality Truck - 2006 GMC Sierra 1500
  By Darin Peratalo - December 22 - 4:26 am

  This truck has been in the shop more times than my 3 other trucks total.The transmission has been out of the truck 6 different times for different problems. The front wheel bearings have been replaced. The brakes & rotors have been replaced twice. Torque converter has been replaced & still vibrates through the gas pedal at 56 mph. All in less than 46000 miles. I do not pull anything. Even GM just blew me off. I should have pushed the lemon law.

  Very Nice Truck - 2006 GMC Sierra 1500
  By gkway - November 14 - 4:36 pm

  Bought this truck after testing every full size on the market. I liked the F- 150 but nobody was willing to be half way reasonable. Toyota thinks to highly of the Tundra, and Dodge is a major gas hog. I am already getting over 17 mpg in the city and 21 mpg on the highway, and that is with less than 2000 miles on it! The seats are very comfortable on long trips, and everything seems to be well laid out. Their is so little road noise it is incredible! I really like this truck!

  Built like a tank...sorta - 2006 GMC Sierra 1500
  By Ian - July 7 - 12:30 pm

  It was a Nevada Edition. I picked this over a Ram & 150 because of the comfy seating and nice black dash and overall better exterior design. Pros: solid ride, Auto 4*4, tons of room, nice rims Cons: At 10K a bearing dropped and ruined the engine and was covered by warranty, little noises everywhere inside, windows not closing all the way and creating road noise. The Spec. Edition Stickers kept on falling off numerous times. Too big for city parking and such, (should have got a mid size.) Crappy speakers blow & distort. Dont think it will be good for the long run so ill give it up for a Dakota i think. Great lease truck though.

  VERY GOOD TRUCK - 2006 GMC Sierra 1500
  By BRIAN - May 21 - 6:56 am

  Enjoy the GMC truck very much. Rides great and can see out very good. My wife loves the truck and the way it handles. Comfort is first class, and the crew cab is wonderful. Our god children enjoy the crew cab very much. No problems so far. Anyone looking for a crew cab truck so look at the GMC.

  Solid Truck - 2006 GMC Sierra 1500
  By Bob Hunt - March 5 - 8:03 pm

  Lots of research online, couple of test drives and a superb track record with my last GM product led me to this truck. Solid truck with great power and resonable fuel economy that has a cabin as comfortable and quiet as any large sedan. Guages and controls are thoughtfully laid out. Driving visibility is excellent. Responsive handling and braking. Look forward to keeping this truck for at least the next 10 years. Id recommend the Sierra to anyone who wants a great looking and reliable truck for a good price.

  Sick Puppy - 2006 GMC Sierra 1500
  By Melvin Richardson - February 8 - 3:16 pm

  The dealer had installed 20" wheels and tires on this truck and it looked good. I ask if it had the same rear end I was trading and they said " I think so" so old trusting Melvin didnt check. It turns out I got a 3.23 rear end with a 5.3 engine and oversize wheels and it drops out of overdrive to go over interstate overpasses if your speed is less than 65 MPH. Driving less than 50 mph it drops a gear if you touch the gas pedal. My wifes Toyota 4 runner drives better, just no hauling or towing capacity.
