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 The Quadrasteer four-wheel steering option has been dropped, and the optional camper-style mirrors have been replaced by a folding and extending design with a built-in convex spotter glass.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

  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.

  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.

  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

  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.
