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 The Quadrasteer four-wheel steering option has been dropped, and the optional camper-style mirrors have been replaced by a folding and extending design with a built-in convex spotter glass.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

  Love my V-8 Z71 Crew Cab - 2006 GMC Sierra 1500
  By Hartwell - March 5 - 11:36 pm

  Interior is roomy and very comfortable for all on long trips. I added a camper shell and roof rack. This truck can hold a ton of gear, and haul your boat, and family and still get 17 MPG. I hunt and fish in the south east so I use 4WD off road and at boat ramps, works great, easy to swich in out 2 to 4 to automatic 4WD. I compared Nissan, Toyota, Ford, and Dodge. At the time of purchase this was the best value by far at the time of purchase. I also have a superb 97 Sierra 2WD approaching 200K, I hope I get the performance and long life with this 06. Note:I had the same wheel bearing issues as others and was covered under 3/36k bumper to bumper warranty, dealer warranty service was great.

  Proud GMC Owner - 2006 GMC Sierra 1500
  By Mike - March 1 - 9:26 pm

  I started out with a Chevy 89 Silverado of which I still have. It now has 372,000 miles on it and it still has the original motor. I have never made any repairs on the motor. The valve cover has never even been off of the head. Ive had several trucks since then. My most recent truck was a 2002 Chevy LT. It had 150,000 miles on it when I traded it. It had never been in the shop except for oil changes and 1 brake job. Im now driving a GMC SLT. I would be crazy to drive anything but a GMC product.

  I love my Sierra - 2006 GMC Sierra 1500
  By W. Oates - November 13 - 6:13 am

  I traded my bullet proof Chevy for this GMC and I havent been disappointed. I Use my truck as a daily driver and as a work vehicle. Im in construction and my Sierra sees a lot of heavy use for a 1500 and does the work of a 2500 handily. I dont baby this truck at all and it rarely gets a bath. I love the roomy interior and power this truck gives me. ITS a V6!! Its zippy and maneuverable. Love the gas mileage and power was a trade off I thought Id have to give on a little but Im not let down by the 4.3 V6.

  New Year New Truck/Great Truck Great Yr - 2006 GMC Sierra 1500
  By Darkcloud - October 10 - 7:40 am

  I picked up this truck on New Years Day. Have already driven over 250 miles. Power heated leather seats are very comfortable. Interior is luxjurious and instruments and gauges are well positioned, very readible for day and well illuminated for night driving. XM Satellite radio with Bose sound system is incredible comnbination that gives exceptional listening experience. Beautiful and functional interior styling. 4X4 has great handling on highway and very nimble in city traffic. Wind noise is almost imperceptable when driving at highway speeds. Park feature of power exterior passenger mirror makes parallel parking a full size truck as easy as parking an automobile. This is a well build truck.

  By Gilby40 - July 22 - 4:10 pm

  Truck was very good for 1st 2 years....After that Ive had to replace a wiring harness that caused the 4wd to fail and now a front end hub dealer said was caused by a pot hole and or/ moisture buildup (no way! I would have remembered hitting something that hard) ...The repairs are over $900.00 so far...I fad 2 other GM trucks since 92....This is MY LAST GM anything....I can hardly wait to see what will happens when god help me I go over 50,000 miles.

  Not bad...but - 2006 GMC Sierra 1500
  By SF Agent - June 4 - 9:16 pm

  Bought new at the end of 2005. Love the exterior styling and the interior design is quite good. I bought mine loaded with everything possible. One minor problem, the transmission went out at 64000. I drive on the highway to my office and back, thats it. The truck has never pulled anything or even been in 4WD. My dealership did lobby GM and they went half on a new transmission, so I was out $1500, but got the new GM transmission with 5 year 100,000 warranty, so I guess that was ok.

  Gas mileage is very good, truck is very comfortable to drive. I have very positive comments from others about the overall appearance. The heated mirrors are very helpful.
