Why it stands out

The 2017 GMC Sierra 2500HD stands out as a heavy-duty pickup that blends work-truck capability with a more upscale feel than many rivals. GMC positioned the Sierra 2500HD with a broader range of trim levels and upscale options than the related Silverado 2500HD, and the brand’s Denali trims were described as more luxurious than the Silverado’s top-tier High Country. For buyers who want a heavy-duty truck that can still feel well equipped, that combination is a major part of its appeal.

For 2017, the Sierra 2500HD offered a 6.0-liter Vortec V8 gas engine and a 6.6-liter Duramax diesel V8 engine, both with six-speed automatic transmissions. Rear-wheel drive came standard and four-wheel drive was available. It was also available in Base, SLE, SLT, off-road AT4, and upscale Denali trims, with Regular Cab, Crew Cab, and Double Cab configurations and 6'5" or 8' beds. The AT4 added off-road hardware and accessories, while the Denali brought a touch of sophistication to the segment.

This generation also helped move heavy-duty pickups toward more modern convenience and safety features. The Sierra 2500HD and 3500HD were the first heavy-duty pickups available with features such as forward-collision warning, lane-departure warning, and adaptive cruise control. Other notable equipment included a 110-volt AC household-style power outlet and an eight-inch infotainment touchscreen. At the same time, shoppers should be aware that these trucks are known for electrical problems, hard-shifting automatic transmissions, glitchy infotainment software and interfaces, and signs of poor build quality such as inconsistent panel gaps, peeling paint, and premature rusting.
