Overview & Reviews

The 2010 GMC Sierra 1500 with the 5.3-liter V8 receives tweaks that yield incrementally better fuel economy, including a standard six-speed transmission and variable valve timing. The 6.2-liter V8 also gets a standard six-speed. The 6.0-liter V8 has been dropped, but all remaining V8s can now run on E85 as well as gasoline. Side curtain airbags, seat-mounted side airbags and stability control are standard on all models, and USB connectivity is optional on SLE and SLT (standard on Denali).

• Smooth and quiet ride, agreeable seats, brawny optional V8s, comprehensive standard safety equipment, upscale interior on SLT and Denali models.

• Large turning circle, bland base interior design, mediocre cabin storage.

  need minor details - 2010 GMC Sierra 1500
  By pierre - April 23 - 10:00 am

  I owned fords for 12 years this is my first GMC. simply love the truck. however the door handle needs to be moved. Minor details. My left knee lays right up against it.And for someone w/bad knees it can get uncomfortable. it is the smoothest riding truck i have owned. But the door handle gets a low grade.

  Very good but could be better - 2010 GMC Sierra 1500
  By nibs - March 11 - 11:48 am

  Just turned 36k on my MY10. Ive the SLT, aluminum 5.3 engine, external oil cooler, Z71 package. 10K of the milage has been done while towing a 12ft enclosed trailer with a sled and gear in the in it. No issues towing but the transmission is clunky. There is squeaking from the doors. The seats could be plusher and have more power settings. Id like to have the option to be able extend the steering wheel as well. I do not like the hard plastic. I like that the Sierra is not a tank of a truck like the Ford, Dodge and Toyota. Fuel economy is ok but I think it could be better. The edge of my rims seem to have deteriorated and that should not have happened so soon.

  Exellent Truck - 2010 GMC Sierra 1500
  By 2010 Seirra - August 26 - 8:26 pm

  This car is simply amazing. Excellent handling, pulls my 8000 pound trailer with ease. Extremely roomy and the seats are amongst the best i have sat in. Wouldnt think twice about buying another.

  GMC Z-71 4x4 All Terrain - 2010 GMC Sierra 1500
  By usapatrick - March 28 - 9:35 am

  We traded in a 2000 Chevy 4X4 ext cab, 5.3 loaded with over 128K trouble free miles. This truck was the obvious replacement. Better looking than the new Chevrolet, now are priced the same with higher resale value. We did not bother with Ford since their warranty and 4 more engines changes showed us instability from within. This truck now has 5000 miles and is up to 16 mpg in town, 20+ mpg hgwy. We got it loaded with leather, buckets etc except sun roof and NAV. The Z-71 4X4 All Terrain package is a bargain. The new 5.3 V8 with the 6 speed automatic is much better than the old power train. We had the dealer put in the wheel well liners, Ziebart and more chrome. Look no further, buy one!

  Still not Toyota Quality - 2010 GMC Sierra 1500
  By North Dakota - November 16 - 10:00 am

  Bought this truck to handle snow (4x4) and because they had a dealership in the small town I moved to. After 6 months of driving and 5k miles, does not match Toyota quality. I traded in a 2003 Toyota Tacoma PreRunner 4-door 4x2 that had 48k miles for this truck. It had zero squeaks and reliability was perfect. The GMC 6 speed transmission slips, shifts hard and hesitates at times. The driver’s door squeaks any time you hit bumps, wash boards or rough pavement. The upside is the fuel economy (better than my Toyota v6). The appearance is bold, which is a personal opinion. Will stick with Toyota next time and make the trip for service in the highly unlikely chance it needs it...

  Generally a good truck - 2010 GMC Sierra 1500
  By tyrex - September 3 - 4:44 pm

  Factory ordered my 2010 SLT 4x4 after my 2007 SLT 4x4 lease expired. Surprisingly, I had a lot of driver seat discomfort with the new truck which I resolved after several months by finding a shop that knew GM seats and showed me how to add foam in the seat and back cushions for extra support. (The 2007 had better seats.) The 6 speed transmission is fine but sometimes is a bit sticky, wanting to stay in a lower gear too long. This truck has been back to the dealer 3 times for minor electronic components problems which were covered by warranty. Fuel mileage is good and better than the 2007. Overall, Im happy with the truck after 16 months and 33,000 km.

  Great Truck, Great Brand - 2010 GMC Sierra 1500
  By Vermonter - March 16 - 10:00 am

  This is the third GM truck that I have owned, and this is the best so far. Very comfortable ride,lots of power,and for a truck it has good gas mileage,17.8 miles per gallon. Interior isnt fancy, but its functional and easy to use. The only complaint is that the headliner rattles a bit, but the dealer says they can fix it. I have had no major issues with my other GM trucks and am not expecting any with the is one, overall great truck!

  New Truck - 2010 GMC Sierra 1500
  By Livwir - September 29 - 11:16 pm

  Z60 package with 5.3L V8 and 3.42 rear gear. Z60 chorme package really stands out on a black truck. It has great get up and go power, the 6 speed transmission takes some getting use to. The 20" rims and tires plus chrome, I get "Good looking truck" comments a lot. The steering wheel control are great, love the blue tooth(hands free phone). I have leather bench seat, the center fold down is just the right height & size with plenty of storage. Everyone that rides in the center complain about the seat beat release.
