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.

  Still not sold on vehicle - 2008 GMC Sierra 1500
  By north star - May 27 - 7:46 pm

  Bought pickup through GM Employee Pricing sale and got very good deal. Not quite sure about pickup, as you can feel the 4 and 8 cylinder activating and de-activating. I have experienced the tranny jerk from a complete stop as well. After changing oil I can smell oil in the cabin for at least the first 1,500 miles before going away, cannot find any leaks anywhere.

  Best of the Breed - 2008 GMC Sierra 1500
  By sknabt - April 7 - 10:46 am

  I decided to replace my SUV with a full-size truck. Choice came down to an 08 Sierra SLT vs. an 07 Tundra Limited (08 Tundra priced way out of my budget) because Ive always bought Japanese. Tundra has nice powertrain but falls short in every other category, especially its bloated price. GMC SLTs greatest selling point is its luxury grade interior. Tundra is very weak here. GMCs shift at any speed automatic 4x4 is far better than Tundras crude hi/lo 4x4. GMC has better crash test scores than the Tundra. This is the 1st full-size truck Ive ever owned but driving it is actually a joy. Parking is a learning experience but the parking assist makes it doable even for a newbie like myself.

  So Far So Good - 2008 GMC Sierra 1500
  By kitch - September 28 - 4:00 am

  Just over 1 week of ownership and I can say I am very pleased with the vehicle. Traded in my Titan LE for this. Interior fit, finish and textures is by far the best Ive seen on any truck. Flip up seats in the rear are nice and a necessity (Tundra I test drove didnt have that). Bose stereo is good and Nav seems easy to operate. Not quite as fun to drive as my Titan was, but still decent. Nice rumble from the stock exhaust. 6 speed tranny is smoooooth. Nice and quiet at 60mph. The AWD is a nice feature to have.

  Great truck so far - 2008 GMC Sierra 1500
  By Jaxman - August 5 - 3:30 am

  Really enjoy the overall look and comfort of this truck. The only real problem that I have had with the truck is the reoccurring "clunking" from the rear u-joint on the drive shaft. Dealer told me that GM is aware of the problem but has not issued a bulletin to properly correct it. Dealer fills it with grease and corrects the cluck for 30-60 days.

  Collapsed Lifter 5.3L AFM - 2008 GMC Sierra 1500
  By ricosha3 - July 26 - 8:48 am

  There appears to be a problem with the lifters in these 5.3L AFM engines that GM wont admit. At 87K miles and 5.5 years old GM garage says lifter is collapsed & wants to replace all 16 @ $3400 & @ my expense. There are lots of posts from drivers with this problem but GM wont admit and GM Customer Service is only lip service... "out of warranty sucks to be you". GM & the dealers dont care... take my advice and buy a Ford. Im stuck with this piece of crap cause I just paid it off and cant afford to buy another $40,000 mistake. BTW: this AFM engine is the same as in current models... beware!

  Powerful and Comfortable - 2008 GMC Sierra 1500
  By spud90 - June 24 - 12:46 pm

  I have never owned a truck before, but I will be moving my son to college and am planning some large home renovations. I bought this truck because dealers are making incredible deals on full-size trucks. A 2.5 ton vehicle with a 315hp engine that gets 15mpg around town is not bad in my opinion. Mine is a 4x2 because I am always on asphalt and it rarely snows in SE Virginia. One tip: Stabilitrak comes with traction control. So consider this option with a 2WD if you want a lower sticker and really dont want/need the extra maintenance and fuel comsumption of a 4WD. This vehicle handles well and is smooth and quiet. It reminds me of a 1977 Lincoln Town Car, only it handles much better.

  This is one amazing truck! - 2008 GMC Sierra 1500
  By Denjhe - May 24 - 12:26 am

  I have had my Black/black 08 Sierra Denali for about 2 months now. Amazing power. Amazing comfort.. Amazing headturner. A beautiful ride in every way. The MPG of 11-12 in the city is a bit of a nuisance but if you spend $42K for a truck you better not whine about the cost of fuel!! If you have the means you should buy this truck.

  Needs Help - 2008 GMC Sierra 1500
  By ted - March 18 - 4:43 am

  No way this truck has 403hp. Had two different 06 Titan trucks that would leave this thing in the dust. Also, the Titans would out tow the Denali. The Bose radio system is whimmpy compared to other trucks and cars I have owned. Handling is so-so. No standard step rails or sprayed in bed liner. Come on GMC this is your top of the line? Get real. I guess this will be the last GMC I will buy.

  Cracked Dash and AFM Lifters - 2008 GMC Sierra 1500
  By chuckaggie - December 20 - 6:27 am

  Just after the power train warranty expires my AFM lifter sticks. $3000 shop bill later and some internet research I know to watch my oil level like a hawk and never purchase another GM. Also the Massive cracks in my dash remind me of 80s GM. Its nice to see them bringing back the materials from their 80s cars. Dont buy one of these trucks. Buy new and dump them when out of warranty.
