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.

  Almost Perfect! - 2008 GMC Sierra 1500
  By Sheepless - February 4 - 2:10 pm

  Before purchasing this vehicle I researched everything about it to the inth degree. I ended up trying to decide b/t the 08 Tundra and the 08 Sierra. I test drove the Tundra and liked it, immediatly following I went and test drove the Sierra and fell in love. MPG is as advertised. I can feel the v8 switch to 4cyl but no one else in the veh can, not a bid geal. My 2 dislikes: the brakes and transmission. Simply put, replace the rear drums with the Tundras disc brakes and replace the 4 speed tranny with a 5 or 6 speed and you have the perfect truck! The 5.3 (w the 4 speed) feels less beefy than you would expect. All in all, I am extremely pleased. I am now a GM man for life.

  DENALI - 2008 GMC Sierra 1500
  By GAGZ - January 28 - 1:33 am

  I just bought this truck, it now has about 6,000m on it. I LOVE it. Lots of power, tows great, very comfortable. Fuel economy stinks but what do you expect with a 6.2L V8? I love the lines of the body and the interior has plenty of buttons! I really dont have any complaints, although for the money i should get a backup camera... Oh ya, and its all time 4-wheel drive, i dont like that at all! NO burnouts!

  GMs Best Kept Secret - 2008 GMC Sierra 1500
  By Miss D - January 16 - 9:53 pm

  I cant wipe the smile off my face! This is the nicest truck on the road. The engine is very strong and the shifts are smooth as silk. Kids love the visibility out the side windows in the rear seat. I added the GM tonneau cover and carpet to the bed, which makes it great for hauling the stuff we haul.....groceries, stroller and hockey bags! The touch screen navigation/stereo is very user friendly and the stereo sounds great.

  GMC all the way ! - 2008 GMC Sierra 1500
  By xmillsx - November 14 - 2:16 pm

  I traded my 2001 GMC 1/2 ton 2WD with 195K miles (it still was strong as heck)for this truck and love it. I have always had good luck and good service from GM trucks. I bought this one with only 25K miles on it. The 8cyl to 4cyl fuel management was a little awkward at first but it is systematic now. On the open interstate at 75mph I have averaged 18mpg+. I was surprised. I have towed a 27ft camper with it with ease. The seating is comfortable even on long drives. Two thumbs up !

  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?

  Best truck Ive ever owned - 2008 GMC Sierra 1500
  By Ralph Vandenberg - June 10 - 11:20 am

  Ive been driving my Denali for about 3000 miles so far. Its an allover amazing vehicle. I havent been able to find any faults whatsoever with the exception of the power being too tempting.... Im going through the gas a bit faster than Id like because its too easy to hit the pedal. I give GMC full marks on this truck, its got to be the best truck on the market right now.

  I love this truck - 2008 GMC Sierra 1500
  By Love this truck - May 26 - 1:23 pm

  I have had this truck for 2,000 miles and about 6 weeks with no problems at all. The truck is solid and fun to drive. I love the exterior design. It looks rugged. I replaced my 1995 Dodge Dakota to get a real truck. I am extremely happy with my decision.

  2008 Sierra 1500 - 2008 GMC Sierra 1500
  By K. Hays - October 15 - 12:36 am

  I have owned this truck for three weeks. This is my first truck and am loving it. We chose the Sierra over the Tundra. Both trucks are very quiet with smooth car-like ride and handling. Sierra got the nod because of ease of access and interior design. So far, I have averaged 16 mpg in non-freeway driving.

  Amazing truck - 2008 GMC Sierra 1500
  By boostedz06 - September 27 - 8:52 pm

  I had been searching for a truck for a while and finally settled on this one. Picked up a used 2008 with 32000 miles and ive had it for over a month and absolutely love it. It rides sooooo smooth like a caddy and gas mileage is pretty good. Highway at 65mph is 23mpg. Toyota cant touch that. I have the 5.3. Havent had it long enough to say how the reliability is, but i know from experience these Chevys are so tough. I have the HD tow package and rear locking diff and it pulls my 20 Cobia like its not even back there... Interior is nice and tight. No rattles, no quirkiness. No engine rattle or cam bump. Sounds As if the motor is not even running. Truck is just pure quality!
