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.

  Glad to be Back - 2008 GMC Sierra 1500
  By Mike - July 16 - 8:30 am

  I traded in my 02 Dodge about 1500 miles ago and I could not be happier. The truck performs great and will haul the snowmobile trailer much better than the Ram did. I am averaging roughly 15mpg which is 3mpg better than the Dodge.

  1st time truck owner - 2008 GMC Sierra 1500
  By t.gooch - May 7 - 2:06 am

  Ive always been a General Motors man since I can remember being allowed to drive the neighborhood mechanics 65 Fleetwood Brougham deElegance. Man that was sweet. Owned nothing but Cadi since 77. Been wanting a truck for the last 10 yrs. Researched Ford, Toyota, Nissan, Chevy, and GMC, of course GMC won me over. I love this truck. Just in hindsight, wish Id gotten the catback system with duals, chrome grille, the tonneau cover and 20s". Owned since Valentines day, 7,000 miles later, several trips to Memphis, one to Tupelo, I cant even complain about the gas mileage (great for a truck), flex fuel management is great. Thanks GMC you hit this one out of the park.

  Been driving 47 yrs and always wanted a pickup. Am I glad I got the GMC Sierra! Very good gas mileage with the 5.3 L 4/8cyl. Ave ~17-18 local and 21-23 highway. No significant complaints. Great comfort and handing.

  Better Than the Rest - 2008 GMC Sierra 1500
  By Bob - March 12 - 9:50 am

  Have not had a truck in a while and I love this one. Great deal, excellent fit & finish and actually drives & rides better than a Volvo sedan I traded.

  Very Nice Truck - 2008 GMC Sierra 1500
  By Pittsburgh-Mike - January 15 - 8:03 pm

  Very nice truck, great build quality. Unlike an ealier review that states the stereo is great, in my opinion the Bose system is a huge disapointment. The Factoy Nav system is great, but the speakers and center dash speaker is terrible. Why GM would even waist the money advertising it is a Bose system is beyond me. For a $45K truck, I would expect a better sounding stereo system. Gas milage is adverage, but you dont buy this truck for fuel milage. Ineterior quality is very nice. Wish GN had a 6 bed option with this truck, 58" bed is a lottle small. Looked at the new Toyota and F150 and I an glad I bought the Denali!

  Best truck ever! - 2008 GMC Sierra 1500
  By Puggy - December 6 - 2:46 pm

  With only 5 weeks and 1,200 miles of ownership my new 2008 GMC Sierra Denali has so far been flawless. I have owned Ford, Chevy and Dodge and this is by far the best of the bunch. Fit and finish is exceptional (for a truck or car), for a truck it has a smooth ride, great power and exhaust note, seamless 6 speed automatic transmission and great interior and exterior styling. It is like driving a full sized luxury SUV with a pick-up truck bed in the back. I couldn’t give 14-16 mpg a 10, but that’s not bad for having 403 hp on tap.

  Loven It! - 2008 GMC Sierra 1500
  By 1st GM in 30 yrs - July 22 - 10:30 pm

  Bought 3 months ago; now have +10K mis. Love it. Been 30yr Ford guy. 1st GM truck ever considered. Bought the wife an 08 HHR liked it & got me to consider a GM again. Traded my 03 F2504dr 4x4 diesel (loved it) had +180k mis;still miss the big 600#ft torq. Dealer offered me a 2-day GMC test drive! Hated the "luxury" dash; reminded me of dads old gran marque, yuk. Wanted more lux but that dash was a deal-brkr. Added SLE pref + NFL pkg & leather/sunroof. Passengers cant but I can notice fr V4 to V8 pwr surge. No tailgate lock!? Will buy one. Has 3.42 rr gear; hard accel into 2nd gear causes rpms to fall out of pwr-band then comes up. Ctr of hood vibrates continually while driving.

  GMC got it Right! - 2008 GMC Sierra 1500
  By J. Barton - June 1 - 8:26 am

  GMC got it (finally) right with this one. Replaced a 2004 with this vehicle, comparison is like night and day. Fun to drive, good mileage, 18.8mpg in first 500 miles. This one is a winner for GMC. So glad we didnt give up on them and head to the Japnese market. Great interior, fine fit and function and good looks too. I love this truck!

  Quality matters - 2008 GMC Sierra 1500
  By retiree - March 8 - 12:36 am

  This 1500 Work is great. Gas economy exceeds sticker rating. Light touch on steering, nicely tuned exhaust for a 4.3L. Standard sound system inc XM is v good. Of all my pickups this one is solid, smooth and a "keeper". Fogs nice touch but not necessary. Ergonomics good.

  Best Truck I ever owned! - 2008 GMC Sierra 1500
  By Bill - March 1 - 10:26 am

  I have built quite a few cars and trucks over the years, this by far out performs them in an all around sense. I got a pretty basic truck for my buisness so thats why comfort is a marked low. My only complaints are that I didnt go bigger with an extended or crew cab, and we need the 6 speed in the basic trucks too. The motor is the most impressive part of this truck. I have a tool box and tonneau, and now acheive up to 22 mpg. The six speed wouldnt work here. My friends Scion TC only get 25-27 mpg average so Im very very happy.
