Pre-Owned 2012 GMC Sierra 1500 2WD SLE Ext Cab in Dallas, TX

The 2012 GMC Sierra SLE Extended Cab is a solid, well-rounded pickup truck that offers a balance of capability, comfort, and durability. With its rugged design and dependable performance, it’s a great choice for truck enthusiasts who need a vehicle for both work and everyday driving.

Performance & Engine

The 2012 Sierra SLE comes equipped with a 4.8L V8 engine as standard, producing 302 horsepower and 305 lb-ft of torque. A more powerful 5.3L V8 is available, delivering 315 horsepower and improved towing capacity. Both engines offer decent acceleration and smooth power delivery, while the six-speed automatic transmission (on select models) enhances fuel efficiency and towing capability.

Towing & Capability

One of the standout features of the 2012 GMC Sierra Extended Cab is its towing capability. Properly equipped, it can tow up to 9,600 pounds, making it a great choice for hauling trailers, boats, or work equipment. The Z71 Off-Road Package (if included) enhances off-road handling with skid plates and an upgraded suspension system.

Interior & Comfort

The Extended Cab configuration provides four doors and seating for up to six passengers, though the rear-hinged back doors can be slightly inconvenient in tight spaces. The SLE trim features a well-designed interior with soft-touch materials, power accessories, and available dual-zone climate control. While not as luxurious as its Denali counterpart, the cabin is comfortable and practical for daily use.

Technology & Features

For a 2012 model, the Sierra SLE offers a respectable array of features, including:
? AM/FM/CD audio system with available Bose upgrade
? Bluetooth connectivity
? Available touchscreen infotainment system
? Steering wheel-mounted controls
? Remote keyless entry & available remote start

However, it lacks some of the more modern tech found in newer trucks, such as Apple CarPlay or advanced driver-assist features.

Fuel Economy

The 2012 Sierra SLE Extended Cab has a fuel economy rating of around 14-20 mpg, depending on the engine and drivetrain configuration (RWD vs. 4WD). While it’s not the most fuel-efficient truck in its class, it’s on par with similar full-size pickups of its era.
