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.

  Overall a great truck - 2008 GMC Sierra 1500
  By EddieH - April 14 - 11:16 pm

  Overall I love this truck. I LOVE the styling, and its very comfortable to drive. There are a few nitpicking things though, I hate the hesitation when you give it gas suddenly. I am told this is due to GM using "torque management" in their PCM tune. Ford and Dodge do not this. This is probably the only real disappointment. The others are small things like when you hit the recirculation button on the AC, then turn the AC on, it defaults back to outside air, you have to hit the recirculation button again. Drives me nuts. The mileage is about what you would expect from a truck this size and engine size. Overall, I love the truck..the quality is very good.

  08 Sierra Denali - 2008 GMC Sierra 1500
  By Jeff B. - March 21 - 5:50 pm

  This 1/2 ton is awsome. 403 HP All wheel drive makes this a blast to drive. very comfortable. pulls my 24ft enclosed trailer and 26ft camp trailer pretty decent. 15-17 mpg not too bad for 400 hp. stabillatrack and speed sensitive steering make this truck handle very well. I had a 400+hp 2005 Duramax crewcab that I loved and traded it for this. I realy love this truck!

  Check carefully before you buy - 2008 GMC Sierra 1500
  By txcwby - June 29 - 2:16 am

  Overall, i would not buy this truck again due to repair costs. At 104,000 miles (notice its just outside the warranty) engine heads both cracked - with the mileage and the reported issues about oil usage and AFM related issue, it makes more sense to replace with a GM crate engine than to solve part of the problem. Mileage on E85 is 14mpg in 2wd if you are an extremely light footed driver. With 87 octane, the average mpg (light foot) is 18mpg-19mpg in hilly terrain. As a cowboy and rancher, my vehicle is my lifeblood and cost of ownership and reliability is key. This truck just hasnt met the minimum expectations. Cost for new engine at GM dealer - $7,898.77

  08 Sierra 1500 - 2008 GMC Sierra 1500
  By blurry25 - April 30 - 3:46 am

  Coming from a Honda Civic the Sierra 1500 feels like a monster. What a dream to drive. I actually enjoy driving to work now. One of the first things I noticed was how quiet the ride is. With the windows up road noise is virtually none existent. Ive been getting around 16.6mpg with all around driving. I suspect that will go up as the motor breaks in, but hey if youre looking for fuel economy buy a prius and just hope that someone in a 1500 doesnt hit you. I highly recommend getting the remote start option. I always start the truck a few minutes before I leave and it either turns on the heater or AC depending on the inside temp of the truck. Nothing like hoping into the perfect climate.

  This is an extremely capable truck. Comfortable, tracks nicely and does what it is supposed to. Work. Wish the fuel economy was better but this is a work truck.

  worst truck i have ever owned. - 2008 GMC Sierra 1500
  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.

  Best Truck Ever - 2008 GMC Sierra 1500
  By jcn7vc - February 23 - 1:16 am

  I have only driven this truck for a week now, but I love it more than any other car I have every touched. The gas mileage is better than advertised, it does very well in the snow and on icy roads. It looks better than the pictures. It handles like a car on the road and a truck off the road. Perfect for any situation. Lots of room in the crew cab, and the bed, although short, is still long enough for most items. I really love this truck!

  I love this truck - 2008 GMC Sierra 1500
  By goblue16 - February 8 - 1:03 pm

  The truck is solid and fun to drive. I went from a Dodge Dakota which I loved, but this is a real truck compared to the 1995 Dakota. Very rugged looking interior that should look good for years. The handling is excellent and it takes train tracks much better then any other vehicle I have been in. I have 1600 miles on it and have not one issue with the truck to date. I have received several compliments about my truck and I love teh new Stealth Gray color that I chose. The 170 degrees that the back doors open is extremely handy. Mileage is a little dissappointing to date at 15.1, but that is with only winter weather.
