2010 GMC Sierra 1500 Review: Our expert's take

Vehicle Overview
The GMC Sierra 1500 and Chevrolet Silverado share the same platform, but the GMC product is often positioned as a more upscale offering. Mechanically, the trucks are the same. There might be slight differences in curb weight and payload, but they share the same powertrain and chassis components. There are five engines and five suspensions in the lineup.

The Sierra comes in regular, extended and crew cab forms. Standard (6-foot, 6-inch) and long (8-foot) cargo beds are available on regular and extended cabs, while the crew cab gets a short (5-foot, 9-inch) bed. All configurations are available in two- or four-wheel drive. The Sierra comes in four trim levels: Work Truck, SL (crew cab only), SLE and SLT. Most V-8 models are rated to tow around 9,000 pounds, but some models get more than 10,000 pounds with an enhanced trailering package.

New for 2010
GM has dropped the long-running 6.0-liter V-8 engine from the Sierra lineup, leaving the powerful 6.2-liter V-8 for heavy towing needs. The rest of the Sierra’s eight-cylinder lineup benefits from increased availability of its new six-speed transmission for regular and extended cab models equipped with the 5.3-liter V-8. Also, the 4.8-liter and 5.3-liter V-8 engines have been enhanced, with variable valve timing for improved emissions and better fuel economy.

Those with portable MP3 players can connect and play their music collections with the truck’s audio system through a USB connection. Standard side curtain and side-impact airbags are welcome safety additions.

Exterior
While GM is trying to differentiate the Silverado and Sierra, the common silhouette is hard to overcome, even with unique front fenders, grille, bumpers, headlamps, cargo box and taillamps. There’s also a strong family resemblance with the Chevy Tahoe/Suburban.

  • Very wide rear-door openings on extended cab models to load passengers, cargo
  • Range of 17-, 18- and 20-inch wheels
  • EZ Lift tailgate available

Interior
The Sierra showcases two different interior designs. Work Truck and SLE models are more utility-minded, with large controls and door handles that can be operated while wearing gloves. The SLT offers upgraded materials and a different dash design. The Sierra’s cab is inviting, spacious and well-organized. Leather seating is available on the SLE and standard on the SLT. The SLT also gets a Bose stereo, a 10-way power-adjustable driver’s seat and a heated windshield-washer system.

  • Stadium-style rear seating
  • Available power-sliding rear window
  • Available moonroof
  • Available navigation system on SLE and SLT
  • Available rear-seat entertainment system

Safety
GM is aggressive in promoting the benefits of OnStar 8.0. New-truck buyers get a one-year subscription to the Safe and Sound Plan, after which owners can subscribe annually. If an airbag deploys, OnStar contacts an adviser and can report crash data to emergency services. The Sierra offers roof-mounted side curtain airbags as standard equipment on all trim levels. Seat-mounted side-impact airbags are also standard. An electronic stability system is now standard on all Sierra models.

  • Available ultrasonic rear parking assist
  • Traction control
  • Four-wheel antilock brakes
  • Seat belt pretensioners activate in rear-end impacts

Fair price for truck value

So far I like the truck, time will tell. Motor cars of Gaithersburg has been good to deal with so far, feel they will continue to be a good company to work with and will address any problems that may come up.

I have a love and a hate for this truck

I have the 4.8L 4-speed base model truck with 4x4 extended cab. I got this truck for reliability and for the most part it has pulled through for me so far. It's a ten year old truck with 75k miles and the only major work has been replacing ball joints. O2 sensor, vent solenoid, and battery were also replaced. I like that the 4.8L option doesn't have programming for the 4 cylinder shut off like the 5.3L does. I also prefer my transmissions to have fewer gears as I find feeling the vehicle constantly search for gears while driving is uncomfortable. The truck I have is not a family vehicle, it is a work truck that I wanted for home projects. It's clunky, sometimes it shutters at red lights, it drives like you expect a with truck to drive, but it gets you from point A to point B and starts up and drives as it should every time (knock on wood). The rear cab is too small for any size person to be comfortable but it's nice for storage and to have the 6.5ft bed option. Maintenance has been relatively easy so far although almost nothing has a drain plug besides the engine. I would recommend this model year GMC Sierra as long as it was made in the USA. Steer clear if it was made in Mexico.
