Why it stands out
The 2021 GMC Sierra 2500HD stands out as a heavy-duty pickup that leans more upscale than many rivals. In this generation, GMC offers more trim levels and a wider range of upscale options and features than the related Chevy Silverado 2500HD, and the Denali and Denali Ultimate trims are positioned as the most luxurious choices. For buyers who want a work truck that can still feel well equipped, that broader spread of comfort and premium content is a major part of its appeal.
The 2021 model also benefits from a strong mix of technology and capability. It comes with a 6.6-litre V8 gas engine paired with a six-speed automatic transmission, and it is also available with a 6.6-litre Duramax turbodiesel V8 engine and a 10-speed automatic transmission from Allison. Rear- and four-wheel drive are available, and the cabin can be had in Regular Cab, Crew Cab, or Double Cab form with 7' or 8'2" cargo bed options. Features such as Bluetooth, Android Auto, Apple CarPlay, and Wi-Fi hotspot accessibility help it feel more modern than many heavy-duty trucks, while available touches like 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 add to its everyday usability.
There are trade-offs, though. The 2021 GMC Sierra 2500HD is described as having numerous problems, including check engine lights tied to diesel particulate filters or emissions sensors, sluggish infotainment responses, rough or delayed shifts, electrical glitches, MultiPro tailgate flaws, and faulty trailer brake controllers. It is also noted that these trucks had very high MSRPs when new, so the used market can still reflect that premium positioning.

-Excellent trailering mirrors with lights, allow increased visibility when backing up at night -Engine noise is relatively quiet compared to older diesel pick ups, can order at fast food drive throughs without shutting engine off -Fuel economy is good for a vehicle of this size (I have 3500HD, not 2500HD) -Driver safety features and various camera views are very helpful -Trim version for this review is Denali, with power running boards, really not missing anything significant
