Why it stands out

The 2016 GMC Sierra 2500HD stands out as a heavy-duty pickup that blends capability with a more upscale feel than many rivals. In the third-generation Sierra 2500HD, GMC offered emerging safety features such as forward-collision warning, lane-departure warning, and adaptive cruise control, along with a 110-volt AC household-style power outlet and an eight-inch infotainment touchscreen. It was also available with an All-Terrain package that was not offered on the Chevy counterparts, giving it a bit more personality for buyers who wanted a heavy-duty truck with some extra character.

Powertrain choices were straightforward and work-focused. The 2016 Sierra 2500HD came with a 6.0-liter Vortec V8 gas engine and a 6.6-liter Duramax diesel V8 engine, both paired with six-speed automatic transmissions. Rear-wheel drive came standard and four-wheel drive was available, and the truck could be had in Base, SLE, SLT, off-road AT4, and upscale Denali trims. That range helped the Sierra 2500HD appeal to shoppers who wanted anything from a basic work truck to a more refined heavy-duty pickup.

At the same time, buyers should be aware of the drawbacks that show up in this generation. The truck is prone to electrical problems from flaws in wiring and sensors, hard-shifting automatic transmissions, and glitchy infotainment software and interfaces. Shoppers should also watch for signs of poor build quality, including inconsistent panel gaps, peeling paint, and premature rusting. Even so, owner feedback for the 2016 GMC Sierra 2500HD is generally positive, with praise for its power, reliability, luxurious features, smooth ride, and strong towing and hauling performance.
