2015 GMC Sierra 1500 Overview

Is the 2015 GMC Sierra 1500 a Good Used Truck?

The 2015 GMC Sierra is one of the best used full-size pickup trucks you can buy. It earns high safety and reliability ratings, an upscale and spacious interior, good engine power, and balanced driving dynamics.

Used 2015 GMC Sierra 1500 Performance and Interior

The 2015 GMC Sierra is available in numerous drivetrain configurations. Its standard V6 engine puts out 285 horsepower and 305 pound-feet of torque. Two V8 engines are available: the first produces 355 horsepower and 383 pound-feet of torque, and the second makes 420 horsepower and 460 pound-feet of torque. Paired with either a six-speed or eight-speed automatic transmission, each of the Sierra's available powertrains delivers good muscle for everyday driving or demanding work applications. The Sierra's standard trailering capacity is 7,600 pounds, but it can lug up to 12,000 pounds when properly equipped. Both of those values are competitive with other full size pickups

The Sierra isn't just a muscular hauler – it's fun and comfortable to drive, too. Steering is responsive, and the ride quality is smooth over most surfaces. Denali models come with an adaptive suspension that makes the ride even softer. Rear-wheel drive is standard, but you can also find used Sierras equipped with four-wheel drive. Some models may have the All-Terrain off-road package with a heavy-duty suspension, hill descent control, and a locking differential. 

Fuel economy estimates for the 2015 Sierra range from the base model’s 18 mpg in the city and 24 mpg on the highway to the smaller V8’s 15 mpg in the city and 19 on the highway (with four-wheel drive).

The GMC Sierra is available in two-door Regular Cab, four-door Double Cab, and extended-length Crew Cab body styles, with maximum seating for six. The Sierra's roomy and comfortable seats provide ample space for adult occupants in the back – especially in Crew Cab models. The Sierra boasts premium cabin materials and a quiet ride, even at highway speeds. Each outboard rear seat has a complete set of LATCH connectors, and the middle seat has a top tether anchor.

Like many pickups, the Sierra has few standard features: two USB ports, a six-speaker audio system, and a 4.2-inch display screen. You'll want to find a used model with the available 8-inch touch-screen infotainment system, which is easy to use and functions smoothly. This interface also includes a Wi-Fi hot spot. To keep all your passengers charged and connected, you can find Sierras with up to six USB ports. Other available features include dual-zone automatic climate control, a 110-volt outlet, a premium Bose stereo, a sunroof, a navigation system, and satellite radio. 

All 2015 GMC Sierras are available with a 6-foot-6-inch bed. Regular Cab Sierras are also available with an 8-foot bed, while some Crew Cab models have a shorter 5-foot-8-inch bed. When properly equipped, the Sierra can haul up to 2,270 pounds.

Should I Consider Another Used Sierra 1500?

GMC fully redesigned the Sierra for the 2014 model year, and it has seen only minor changes in the few years since. The 2015 Sierra gained a Wi-Fi hot spot and added magnetic ride control to the Denali trim, while the 2016 model introduced Apple CarPlay and Android Auto as options. If any of those features are important to you, you'll want to focus on the model year they became available – but keep in mind you can likely save money by shopping for an older Sierra 1500.

Which Used GMC Sierra 1500 Is Right for Me?

The 2015 GMC Sierra is available in four trim levels: Sierra (base), SLE, SLT, and Denali. You can also choose from several powertrain, cab, and bed configurations to fit your needs. The best value is a Sierra SLT. This model comes standard with leather seats and the smaller V8 engine, and includes features like remote start and dual-zone automatic climate control. The SLT also gets you features from the lower trim levels, including a touch-screen infotainment system, a rearview camera, and satellite radio.

You may want to consider a certified pre-owned vehicle for the additional warranty coverage. For all of its CPO models, GMC extends its original new-car limited powertrain warranty to six years or 100,000 miles and provides a one-year/12,000-mile bumper-to-bumper limited warranty. GMC CPO vehicles must pass a 172-point inspection. Additional benefits like towing and roadside assistance may be available, so read GMC’s warranty page carefully.

2015 GMC Sierra 1500 and Other Trucks to Consider

Which Is Better: 2015 GMC Sierra 1500 or 2015 Chevrolet Silverado 1500?

Both products of General Motors, the 2015 Chevrolet Silverado 1500 and the Sierra share many of the same mechanicals, underpinnings, and features. This means that both trucks offer great reliability and good performance. The Sierra was designed to be the more luxurious version; the Silverado can't match the opulence of the Sierra Denali. However, the Silverado is high quality in its own right, and you can likely find a Chevy for cheaper than the GMC. Either truck is a great choice, so your decision may come down to how many luxury features you want.

Which Is Better: 2015 GMC Sierra 1500 or 2015 Ford F-150?

The 2015 Ford F-150 tops the class in overall performance. With a lineup of several muscular engines (some turbocharged), the F-150 has the highest towing and payload capacities among full size pickups. It also has poised and responsive handling. For interior comfort and quality, the Sierra beats out the F-150, but both trucks earn praise for their features and technology.
