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.

  A few items - 2008 GMC Sierra 1500
  By John - November 23 - 2:53 am

  Active fuel management is a little disappointing. I thought I would get higher gas mileage. I get higher gas mileage with my 2001 5.3l GMC. It could be GMCs choice of tires. I do like the trucks ride and interior comfort. The cup holder and glove box need work. The owners manual barely even fits in the glove box. All in all it is an 8.

  Great truck at a great price - 2008 GMC Sierra 1500
  By OleMissDispatcher - October 29 - 11:53 pm

  Have owned truck for almost 600 miles and really enjoy the truck. It has 5.3 V8 with the Flex Fuel Management. City driving is ok, highway is a lot better. For a base model, it came fully loaded with all power options, CD, cruise, fog lights, chrome bumpers, towing package, XM, and OnStar (which I think XM and OnStar were standard). Truck can ride rough over unkept streets, but still a lot better than my old Chevrolet Tracker. Air and heat are great. Cant wait to try the 4x4!

  08 SLT Crew Z 71 pack - 2008 GMC Sierra 1500
  By L. Morris - October 19 - 3:06 pm

  Last truck was a 96 Z71 ext cab Chevy. This truck is awesome! I love 99% of it! I chose this, over the somewhat cheaper Silverado, due to the way the dealer treated me and the price they quoted me. No one else could come close to my deal.

  Capable and solid - 2008 GMC Sierra 1500
  By LYNDONGOLDEN - September 30 - 7:40 pm

  I wanted a stylish "basic" regular cab truck. I looked for a comparably equipped Tundra but there were few choices out there...with only leftover 07 models, almost all of them long-bed and white! And none of the base model Toyotas had factory XM radio. So I purchased the Work Truck package Sierra... and Im very pleased. The dash design, controls, seats, driving position, and interior storage all work very well for my tastes. The cargo management system is very usefeul as well. And the 4.8 V8 has a satisfying exhaust rumble. I drive alot in the bumpy inner-city Houston streets, and this truck hamdles it well. This was a good choice, and I beleive it will serve me well.

  What a difference! - 2008 GMC Sierra 1500
  By Sierra - August 28 - 8:43 am

  Immediately drove 2 WD truck (17" tires) to central OH from central FL - 20.2 mpg @ cruise set mostly 75 mph. Returned to FL w/bass boat in tow 15-17 mpg. Ride is super w/effortless handling. Plenty of power with 5.3 engine. I wanted a truck with car type ride. Thats why I got 2 WD with 17" rims.

  I love this truck - 2008 GMC Sierra 1500
  By R Taylor - July 31 - 5:06 pm

  I decided to buy a new truck and chose the new body GMC for several reasons. The overall design is great! The interior is nicer than ever and everything is within easy reach. The big bold grille stands out in a crowd.

  Not a Happy Owner - 2008 GMC Sierra 1500
  By Luke - July 16 - 6:26 am

  I have always been a Chevy man, really needed a new pickup so I went with the GMC. I wanted the 5.3l because it does great in my 01 Suburban. My New 5.3, which has fuel management gets much worse mileage. I get 13.5 MPG at any speed or condition driving, even downhill. Also the 4 sp transmission is clunky, brakes are sticky, interior clothe is Horrible, interior plastic comes apart, body has many mud pockets which will rot the metal and the front tire sprays road wash Into the frame by the front door. I am NOT happy with this truck which now has 3500 miles on it.

  Better then the rest - 2008 GMC Sierra 1500
  By blksiryder - May 10 - 3:30 am

  I just got my new GMC with the 5.3. I love the fact of the fuel managment system. The mpgs could be better but not bad. The engine is a power house. I traded my 2000 turbo diesel for this truck and with the 100k powertrain warranty. I know it will last the the term of the loan. I would buy 2 if I needed them.

  Best One Yet - 2008 GMC Sierra 1500
  By Best One Yet - May 2 - 12:46 pm

  After driving GMC trucks since 1974 this new 2008 Sierra is the best one yet. The interior is outstanding with great back support in the bucket seats; easy accesss to everything on the dash; to great controls on the steering whell. This is the first time for GMC to have cruise control on the steering wheel and it is much easier to operate. Performance is outstanding with the 5.3 engine and my gas mileage is good as well. With the 4-6-8 engine I get 24 to 25 mile to the gallon at 55 mph. Amazing! My friends drive Fords and Dodges and their milage is so bad 10-12 mile per gallon. Too bad they didnt buy a GMC. My company truck is a Ford 4x4 and on a good day it gets 12-13. Really sad.
