Why it stands out

The 2025 GMC Sierra 2500HD stands out for offering a heavy-duty pickup with a more upscale feel than many rivals. In Canada, it is available in Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate trim levels, and the Sierra’s higher-end versions lean into luxury with features such as premium audio, leather seats, and a surround-view monitor. The AT4 models add off-road hardware and accessories including skid plates, off-road suspension upgrades, and a more robust transfer case, giving buyers a clear path toward either refinement or rugged capability.

It also brings a broad mix of convenience and technology features. The refreshed truck includes Bluetooth, Android Auto, Apple CarPlay, and Wi-Fi hotspot accessibility, while available equipment can include remote keyless entry and rear-seat reminders. More upscale models 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 also get a choice of Regular Cab, Crew Cab, and Double Cab body styles, along with 7-foot or 8-foot-2-inch cargo beds.

Under the hood, the 2025 GMC Sierra 2500HD 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. The trade-off is that these trucks had very high MSRPs when new, and used examples can still be expensive. Buyers should also be aware of reported issues with the MultiPro tailgate, check engine lights, rough shifting, infotainment and electrical glitches, and trailer brake controllers.
