2010 GMC Sierra 1500 Reviews

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

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

Warranties Explained

Bumper-to-Bumper

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

Powertrain

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

Roadside Assistance

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

Free Scheduled Maintenance

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.
