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.

Poor Throttle Response - 2008 GMC Sierra 1500
By Sierra Driver - January 19 - 11:26 amThis truck replaced my 2001 GMC Sierra 4wd with the 5.3 motor. The throttle response on the 4.8 motor is pathetic. The traction control is overly sensitive, and the truck jumps out of passing gear too soon. The truck is comfortable, quiet, and handles well. The brakes are a major improvement over my previous 2001 Sierra. I love the lighter weight of the tail-gate.

Average - 2008 GMC Sierra 1500
By APPELSCF - December 12 - 12:03 amThis is my second GMC. I recently traded up from a 2006. Good ride and handling, Like the appearance, gets the same mileage as my 06, averages 18 mpg. I have cloth interior, I liked the old cloth material better. Radio controls are hard to reach. I like the new dual zone controls. The backup sensor is a joke, some of the gauges are blocked by the steering wheel, I really like the new head lights the low beams stay on with the high Beam. Fog lights are cheap. the interior quality is better than my 06

Tuff truck - 2008 GMC Sierra 1500
By tatertot - May 3 - 11:53 amThis truck is great, the wide stance make you feel safe. The handling is great, there is hardly any roal in the suspension when cornering. Believe it or not I jumped my new truck 1 week after I got it. But not purposly. When I did so the landing hurt but the truck was fine. The balance was tweeked but I checked it out and nothing was broke or bent. It drives the same as before.

2008 GMC 1500 - 2008 GMC Sierra 1500
By medic979 - April 4 - 7:20 pmNice truck. However, the transmission shifts hard and catches when leaving from complete stop. Dealer says they have had other customers with same problem and no fix for it, so very disappointed. Was in shop at 2000 miles with this problem and still does it. I looked at Fords and Toyota, quality was better. Why did I buy GM? I liked my selling dealer. Im stuck with this truck that has a catch when leaving from a complete stop. Think twice before purchasing. I do enjoy the truck and if they find a fix for it Ill be happy, but they may be bankrupt first. Till they get their act together, go with Toyota.

Best Truck -- needs a few improvements - 2008 GMC Sierra 1500
By Pete1954 - August 4 - 10:03 pmI love everything about this truck, except for the upholstery. The charcoal colored cloth picks up lint, dog hair, everything and its quite visible. But whats worse, the nap on the upholstery is starting to flake off with only 14K miles! Quite honestly, if I had realized what a tremendous vehicle this was in every other way, I would have gone with the SLT or Denali trim, had leather and not have the upholstery issue. This is a keeper -- guess I will be looking for an upholstery shop.

Great truck so far - 2008 GMC Sierra 1500
By Jaxman - August 5 - 3:30 amReally enjoy the overall look and comfort of this truck. The only real problem that I have had with the truck is the reoccurring "clunking" from the rear u-joint on the drive shaft. Dealer told me that GM is aware of the problem but has not issued a bulletin to properly correct it. Dealer fills it with grease and corrects the cluck for 30-60 days.

Collapsed Lifter 5.3L AFM - 2008 GMC Sierra 1500
By ricosha3 - July 26 - 8:48 amThere appears to be a problem with the lifters in these 5.3L AFM engines that GM wont admit. At 87K miles and 5.5 years old GM garage says lifter is collapsed & wants to replace all 16 @ $3400 & @ my expense. There are lots of posts from drivers with this problem but GM wont admit and GM Customer Service is only lip service... "out of warranty sucks to be you". GM & the dealers dont care... take my advice and buy a Ford. Im stuck with this piece of crap cause I just paid it off and cant afford to buy another $40,000 mistake. BTW: this AFM engine is the same as in current models... beware!

Needs Help - 2008 GMC Sierra 1500
By ted - March 18 - 4:43 amNo way this truck has 403hp. Had two different 06 Titan trucks that would leave this thing in the dust. Also, the Titans would out tow the Denali. The Bose radio system is whimmpy compared to other trucks and cars I have owned. Handling is so-so. No standard step rails or sprayed in bed liner. Come on GMC this is your top of the line? Get real. I guess this will be the last GMC I will buy.

2008 GMC SLT Z71 Ext Cab 6.5 bed # 2 - 2008 GMC Sierra 1500
By schodackbassman - December 14 - 12:40 amThis is my 4th GMC extended cab and my 2nd z71 SLT. Trade my 04 for the 08 because of the great deals over the summer. I loved my 04 but the 08 is hands down a better overall truck. Adjustable everything for the driver including gas/brake pedal. Heated seats, great sound system, upgraded leather seats overall nicer inside. Like the return of drum brakes in the back and nice wheels. EZ lift tailgate is a godsend. Can be open/closed with one hand. Better heater then the 04 but still slow to warm in stop/go traffic on cold mornings below 20 degrees. Remote start is great, ride is great, looks are good, & no more touchy ABS system. 17" Wrangle ATS much better than cheap Bridgestones.
