Why it stands out

The 2019 GMC Sierra 2500HD stands out as a heavy-duty pickup that blends work-truck capability with a more upscale feel than many rivals. It sits in a lineup that was offered in more trim levels than the related Chevy Silverado 2500HD, and the Sierra’s Denali and Denali Ultimate trims are described as more luxurious than the Silverado’s top-tier High Country. For buyers who want a heavy-duty truck that can feel more polished inside, that broader range of upscale options is a major part of its appeal.

It also brings a strong mix of technology and utility. The truck was available with Bluetooth, Android Auto, Apple CarPlay, and wifi hotspot accessibility through the GMC infotainment system, while higher trims could add a Bose Premium audio system, power-adjustable front seats, chrome grille trim, dual-zone automatic climate control, and power-folding tailgate options. The Sierra 2500HD also offered a 6.6-liter V8 gas engine with a six-speed automatic transmission, plus an available 6.6-liter Duramax turbodiesel V8 with a 10-speed automatic transmission from Allison, along with rear- and four-wheel drive. Cab and bed choices were broad as well, with Regular Cab, Crew Cab, and Double Cab body styles and 7' or 8'2" cargo beds.

At the same time, this generation is not without drawbacks. The source notes problems such as check engine lights tied to diesel particulate filters or emissions sensors, sluggish infotainment responses, rough or delayed shifts, electrical glitches, MultiPro tailgate issues, and faulty trailer brake controllers. It also says these trucks had very high MSRPs when new, so the 2019 GMC Sierra 2500HD can be appealing for its equipment and upscale presentation, but shoppers should be prepared to inspect carefully and budget accordingly.
