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.

  By trucksucks1 - February 28 - 3:14 am

  Truck has 34000 miles on it. Main turn signal switch went out, Door lock switch out, Airbag sensor out, Master window switch out ($400) for a switch! Truck now will not engage the starter, so its in the shop again. Do not buy any GMC or Chevy truck! Going back to Dodge.

  not what i exspected fora new truck - 2008 GMC Sierra 1500
  By jeff hall - November 7 - 6:46 pm

  Tail lights were replaced after filling with condensation, blinkers get a mind of there own, "when I turn the blinker on the light flashes on dash but no clicking sound from the relay no the blinker even works on the outside. Last night partially the lights on the dash "half" of them when off and on twice and came back on. As I was driving in a snow storm I noticed something flashing from the front of the truck. Havent found what it might be because when it stopped the truck and did a walk around it to see if all the lights were working they were and got back into the truck and when I got home turning into my drive there was the flash again. If its happening when I take it in then what?

  First GMC Sierra 1500 - 2008 GMC Sierra 1500
  By Sierra2008 - August 5 - 10:00 am

  This Truck has been nothing but problems. Starts out with, 6 door locks being replaced, A new radio, rattles, dir seat broke, steering wheel Bearing went bad. Now no warranty left, Have HVAC issues, it does not start up on the first try dealer told me it’s the fuel pump, which will cost 1000 bucks. I cannot believe GM would even put-out this truck and call it professional grade. What a POS. The transmission shifts terribly, the driveline is noisy with clunks and the engine has oil consumption issues. IF YOU HAVE AN LC9 alum block 5.3L AFM ENGINE OR CREW CAB CHECK THE OIL. You will need new pistons installed and an AFM oil shield after 30,000. Im going back to a FORD F150

  GMC should change there initials... - 2008 GMC Sierra 1500
  By jojo123 - June 4 - 9:53 am

  To JUNK!!!! Too many problems with check engine light coming on constantly. For some reason, the gas cap constantly comes loose. GM should provide better stock tires. Had a flat from a piece of limestone gravel. Dealer told me I should drive on better roads! (Its a truck, isnt it?) Should have stayed with Ford. Big mistake to buy this truck. Dealer isnt interested in helping very often. It takes multiple visits to fix one problem. Maybe if the service manager got off his lazy [violative content deleted] of his chair, it could be fixed. Last GM product EVER!

  By jorge - February 3 - 4:13 pm

  although its a beautifull truck mine was poorly crafted i found rattling noise inside the cabin, brakes make alot of noise, and has poor stability,gmc needs to improve the performance on their vehicles and keep their promisses with warranties.

  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.

  GMC Lemon - 2008 GMC Sierra 1500
  By First & Last GMC - October 1 - 9:23 am

  First & last GMC truck(2008 SLE 4- Wheel Drive, 5.3 engine). I just traded this truck with 1900 miles on it. The truck had vibrations in the front and passenger door. 3 trips and 14 days in the dealership did not solve the problem. My personal mechanic said the problem was in the powertrain. I gave up and took a loss. I told this story to General Motors and have not even had a reply! Fool Me Once!
