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.

  GMC 1500 seat quality - 2010 GMC Sierra 1500
  By John - August 12 - 10:00 am

  I have 2010 GMC 1500 SLE with manual seats. The seat back has extra play consequently starts and stops cause the back of the front seat to move because of a poor fit or extra clearance. The dealer says they are all that way and showed me another truck and it was the same, I find it extremely annoying, I will probably have to find a good upholstery shop and pay to repair a sloppy seat back. Not happy with build quality.

  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.

  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.
