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 The Quadrasteer four-wheel steering option has been dropped, and the optional camper-style mirrors have been replaced by a folding and extending design with a built-in convex spotter glass.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

  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.

  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

  My Last GM product - 2006 GMC Sierra 1500
  By wdh2 - May 8 - 6:07 am

  I bought this truck used with 50K miles; GMC certified + factory warranty remaining for 10K more miles. I have had lots of problems out of this truck. In less than 5 months of ownership; -the center console shorted out -the rear brakes locked up and burned up the rear-end which had to be replaced (not covered under warranty) -Lots of vibration in front end- the front end came loose from the truck and had to be re-welded -Power steering kept cutting off when turning (frayed line attributed to the front end separation) -Short in heated seats -Tail gate had to be replaced and now the new one will not open (dealer installed) -Transmission is now slipping This truck has only seen pavement

  2006 GMC 1500 ext-cab 4x4 - 2006 GMC Sierra 1500
  By poppyseed - June 14 - 9:38 am

  Initially had a few Q.C. issues with the speakers blowing, weather seal falling off, passenger arm rest detaching and the rear brake light assembly falling off, the real fun began. at 57k the tranny blew. Shortly after the transfer case failed. At 70k the drive side wheel bearing failed. 6 months later same bearing failed. At 75k the rotors replaced for 2nd time. Solenoid on gas tank replaced. Steering shaft knuckle replaced. Truck quivers and rattles over the smallest of bumps after 79k miles. Forgot to mention the rust on rocker panels, doors and wheel wells. The truck is such a lemon my kids make fun of it.
