Why it stands out

The 2023 GMC Sierra 2500HD stands out for offering a heavy-duty pickup with a more upscale feel than many rivals. In this generation, GMC gives it a broader range of trim levels and upscale options than the related Chevrolet Silverado 2500HD, and the Denali and Denali Ultimate trims are positioned as especially luxurious. It also brings a strong mix of convenience and technology, with available Bluetooth, Android Auto, Apple CarPlay, Wi-Fi hotspot capability, remote keyless entry, rear-seat reminders, a Bose premium audio system, power-adjustable front seats, chrome grille trim, dual-zone automatic climate control, and power-folding tailgate options.

Mechanically, the 2023 GMC Sierra 2500HD is offered with a 6.6-litre V8 gas engine paired with a six-speed automatic transmission, or a 6.6-litre Duramax turbodiesel V8 engine paired with a 10-speed automatic transmission from Allison. Rear- and four-wheel drive are available, and buyers can choose from Regular Cab, Crew Cab, and Double Cab body styles with 7' or 8'2" cargo beds. The AT4 models add off-road hardware and accessories such as skid plates, off-road suspension upgrades, and a more robust transfer case, while the Denali trims focus on luxury cabin features.

That breadth makes the truck appealing to shoppers who want a work-capable heavy-duty pickup that can also be configured for comfort or off-road use. At the same time, used examples deserve careful inspection because this generation is known for issues including check engine lights caused by diesel particulate filters or emissions sensors, sluggish infotainment responses, rough or delayed shifts, electrical glitches, MultiPro tailgate faults, and faulty trailer brake controllers.
