Overview & Reviews

Coming off a redesign last year, the 2008 GMC Sierra 1500 has only minor changes this year. Satellite radio is now standard equipment and an integrated trailer brake controller is optional. GMC says it will also be offering 22-inch wheels (as a dealer accessory) and a flashier version of the Z71 Off-Road package called the Sierra All Terrain.

• Refined and very quiet ride, pleasing fit and finish inside, seats are comfortable for long drives, comprehensive list of safety equipment.

• Larger turning circle than most rivals, mediocre interior storage and cupholders.

  Compare Denali to any other 1/2 ton. - 2008 GMC Sierra 1500
  By bob - March 27 - 11:53 am

  I went into the truck market expecting to buy a Tundra because I have had such good luck with Toyotas.To say that I was pleasantly surprised with the Sierra is an understatement. I priced a loaded SLT with the 6 liter engine and the Denali was about the same price. It was an easy decision to buy the Denali because of the extas like the 6.2 liter motor and six speed tranny to mention a few. This truck will run with the Tundra, rides better, handles better and has a more refined interior. My wife prefers the Denali over her Acura RL, which she loves. My freinds can not believe the power with the engine and tranny combination. Do yourself a favor and test drive a Denali when looking for a new truck!

  GMC Sierra Denali AWD - 2008 GMC Sierra 1500
  By Brent - March 6 - 9:33 pm

  Very impressed with this vehicle. Sold my 175K mile Sierra and due to its excellent performance, Im sold on GMC. The Denali drives and handles great. 18mpg hwy and 16.4 in town. Not bad for a 6.2 ltr V8. My previous 4.8 ltr V8 only beat that by 1mpg! My vehicle came loaded w/options and couldnt pass it up for $38.5K. With gas prices I think they are really having to come down on these things. Very quiet ride on the highway and around town. It does need more storage compartments/center console organizer. I would rather the center console open from the side rather than front. Its somewhat awkward and has a rather flimsy spring hinge.

  Youre missing out... - 2008 GMC Sierra 1500
  By DirtyD - February 24 - 11:50 pm

  I test drove every make of truck and this one got my money. Sharp truck and a real headturner with my Black Z-71. Power is great and off road ability is only topped by a Wrangler (Im an avid Jeeper). Cant say enough about the ride comfort and quiet demeanor, very nice interior. I was looking for a truck, not a Prius or Cadillac. This is the perfect truck.

  Built to last - 2008 GMC Sierra 1500
  By Big Lek - February 3 - 6:20 am

  I never owned a GMC. Everyone i talked to said GMC was just a high priced Chevrolet, now i know the diference. The styling, the ride quality, and low cabin noise are just a couple things that i noticed that were a lot diferent. I also like the fact that this truck is almost all US made. This truck is great.

  By mesalaxdad - January 20 - 12:02 pm

  So Ive had the truck less than a year. It has only 18k on it. Ive had to replace two door lock switches. Ive also replaced a leaky oil pan gasket. Its been in the dealership 3 times. When I wash it the door moldings leak for hours.

  Poor Throttle Response - 2008 GMC Sierra 1500
  By Sierra Driver - January 19 - 11:26 am

  This truck replaced my 2001 GMC Sierra 4wd with the 5.3 motor. The throttle response on the 4.8 motor is pathetic. The traction control is overly sensitive, and the truck jumps out of passing gear too soon. The truck is comfortable, quiet, and handles well. The brakes are a major improvement over my previous 2001 Sierra. I love the lighter weight of the tail-gate.

  Excellent Truck - 2008 GMC Sierra 1500
  By Bryan2008 - January 5 - 8:03 pm

  GMC really did a great job with this truck. I really love the power of the engine and the comfort. I do not drive it much trying to keep those miles off of it. But when I do it is a treat and makes me appreciate life more. It definitely is deserving of much kudos. Thanks again GMC for a really great vehicle.

  Average - 2008 GMC Sierra 1500
  By APPELSCF - December 12 - 12:03 am

  This is my second GMC. I recently traded up from a 2006. Good ride and handling, Like the appearance, gets the same mileage as my 06, averages 18 mpg. I have cloth interior, I liked the old cloth material better. Radio controls are hard to reach. I like the new dual zone controls. The backup sensor is a joke, some of the gauges are blocked by the steering wheel, I really like the new head lights the low beams stay on with the high Beam. Fog lights are cheap. the interior quality is better than my 06

  Best LuxuryTruck/ SierraDenali AWD 6.2 L - 2008 GMC Sierra 1500
  By X. Joseph - August 13 - 9:56 am

  Just bought this incredible machine. I bought it for the engine even though gas prices are high. It gets decent mileage for its powerhouse 403hp 6.2 liter engine. Best stock V8 horsepower of any brand and you still can chip it to 500hp +. The interior is refined and classy. It looks like my BMW 5 series inside. You can buy a regular fully loaded 4X4 crew and pay the same price. I feel this is the best deal in luxury trucks.approx. 40-45k depending on options. The cadillac escalade has become synonomous with bling bling and hip hop.- it is a little to showy for me. This Denali is not so showy and has a beautiful interior. So far no problems as I am babying it until 1000 miles. Super quality.
