2011 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 five trim levels: Work Truck, SL (crew cab only), SLE, SLT and Denali.

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 2011
There are only minor changes for the 2011 Sierra half-ton pickup. The Sierra gets the latest OnStar 9.0 system, revised exterior color offerings and insulating enhancements that help reduce wind noise.

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. The upscale Denali trim features a unique chrome grille and wheels. Exterior features include:

  • 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. Denali trim is the most luxurious package available for a GM pickup with upgraded trim and materials. Interior features include:

Dependable Truck

by Roy from Loogootee on November 8, 2017

I really enjoy driving the powerful 6.2 . Truck handles well, could do better on fuel economy. The interior design is a step behind competition. I really do like the integrated towing controls included. Read Full Review

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.
