Why it stands out

The 2023 GMC Sierra 2500HD stands out as a heavy-duty pickup that blends work-truck capability with a notably upscale presentation. In the fourth generation, the Sierra 2500HD is offered in more trim levels than the related Chevy Silverado 2500HD, with a wider range of upscale options and features. The Denali and Denali Ultimate trims are described as more luxurious than the Silverado version’s top-tier High Country trim, which helps give the GMC a more premium identity in this segment.

For 2023, the Sierra 2500HD’s appeal also comes from its broad mix of technology, comfort, and configuration choices. The truck is available with Bluetooth, Android Auto, Apple CarPlay, and wifi hotspot accessibility through the GMC infotainment system, and available features include remote keyless entry and rear-seat reminders. Higher trims can add a Bose Premium audio system, power-adjustable front seats, chrome grille trim, dual-zone automatic climate control, and power-folding tailgate options. Buyers can also choose from Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate trims, along with Regular Cab, Crew Cab, and Double Cab body styles and 7' or 8'2" cargo bed options.

It is not just about comfort, though. The Sierra 2500HD comes with a 6.6-liter V8 gas engine paired with a six-speed automatic transmission, and it is also available with a 6.6-liter Duramax turbodiesel V8 engine and a 10-speed automatic transmission from Allison. Rear- and four-wheel drive are available, and the AT4 models add off-road hardware and accessories such as skid plates, off-road suspension upgrades, and a more robust transfer case. At the same time, used shoppers should be aware that fourth-generation versions have a number of reported problems, including check engine lights, infotainment sluggishness, rough or delayed shifts, electrical glitches, MultiPro tailgate issues, and faulty trailer brake controllers.
