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.

  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.

  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.

  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.

  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 !

  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.

  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!

  News of GMs dimise greatly exhaggerated - 2008 GMC Sierra 1500
  By The Needle - July 19 - 10:46 am

  A family member bought the Tundra in Oct.07-Toyota is making a big deal out of their 5.7L engine etc...the Tundra is a nice truck--but I decided to go with the Sierra for several reasons: Better road manners--especially on the freeway--very tight steering. Much more luxurious, refined and thought-ought interior. Everything inside is beautiful and solid--not an easy feat to accomplish. Classic looks--yet modern. GM really hit a home run with this design. I get more looks and questions than when I had a Porche. Perfect size Crew-cab. This is the biggest downer with Tundra--you either get the smaller ex-cab or the huge double--bigger than Dodges. Bad combo. GM hands down!
