Is the 2022 GMC Sierra 2500HD a good car?

Generally — the 2022 GMC Sierra 2500HD earns 4.43/5 from owners and 7.67/10 from our experts. The standout strength is Form and function at 9/10.

Drivers repeatedly praise its smooth and powerful ride, along with its comfort and features. The user feedback also points to strong value, especially with the Black Diamond Package, which fits the truck’s role as a heavy-duty pickup that still aims to deliver everyday usability and useful equipment beyond towing and hauling.

That broader appeal lines up with the overview: you’re looking at a truck built for demanding jobs, but one that also tries to balance off-road ability, design, infotainment, trailering technology, and safety. 22.2% of listings are priced as good or great deals, so there is some room to shop selectively.

Is the 2022 GMC Sierra 2500HD reliable?

Owners rate it 4.43/5, a solid signal of long-term satisfaction.

User feedback highlights a smooth, powerful, and dependable-feeling truck, with many owners describing it as a vehicle they can count on for capability and comfort. The expert evaluation also points to strong powertrain performance and an excellent Allison 10-speed automatic transmission with the Duramax diesel, which supports the impression of a truck built for hard use.

The cost-effectiveness notes add that the Duramax diesel comes with a five-year/160,000-kilometre powertrain/drivetrain limited warranty, which is a useful ownership perk if you plan to keep the truck for the long haul.

For used buyers, the main long-term ownership risk is that some owners reported quality concerns, so a careful inspection and service-history review matter.

What should I look for when buying a used 2022 GMC Sierra 2500HD?

Key things to evaluate:

• Trim level: The Pro trim is aimed at fleet and work use with cloth seats and basic amenities, while the SLE and SLT add more comfort and mainstream appeal. The AT4 is the off-road-focused choice, and the Denali is the luxury-oriented trim. The AT4 and Denali are offered only in crew cab form.
• Powertrain: The Sierra 2500HD uses 6.6-litre V8 engines, with a standard gas engine and an optional Duramax turbodiesel. The diesel pairs with an Allison 10-speed automatic and delivers abundant power, while the truck can feel jittery when unladen.
• Safety package: Available driver-assistance features include automatic emergency braking, forward-collision alert, lane-departure warning, lane-keeping assistance, blind-spot monitoring, rear cross-traffic warning, following distance indicator, hill-descent control, HD Surround Vision, a rear-seat reminder system, Safety Alert Seat, and front and rear park assist. The Teen Driver system is standard.
• Infotainment: Depending on trim, you get a 7-inch or 8-inch colour touchscreen. Wireless Apple CarPlay and Android Auto are standard on SLT and above, available on SLE, and not offered on the base Pro trim. Navigation is standard on Denali and available on SLT and AT4, and SLE and above add SiriusXM satellite radio, a WiFi hotspot, and OnStar with connected services.
• Fuel efficiency: During testing, the truck averaged 16.3 litres per 100 kilometres in combined driving without a trailer. If you tow or haul regularly, expect fuel use to climb.

Which 2022 GMC Sierra 2500HD trim should I buy?

The 2022 GMC Sierra 2500HD is offered in 5 trim levels: Pro, SLE, SLT, AT4, Denali.

Here's the short version:

• Pro: This is the work-focused starting point, with cloth seats and basic amenities. It makes sense if you want maximum capability without paying for comfort or tech extras.
• SLE: This is the first step up for shoppers who want more everyday usability. It adds some creature comforts and, compared with Pro, opens the door to more available tech.
• SLT: This is the best-value trim for many buyers because it brings a stronger mix of comfort and technology, including standard wireless Apple CarPlay and Android Auto.
• AT4: This is the right pick if you want the off-road-oriented setup, including the rugged equipment and trail-ready character highlighted in the test drive.
• Denali: This is the luxury choice, with the most upscale positioning and the strongest emphasis on premium features.

For safety equipment, the available driver-assistance systems are broad, but you’ll want to check exactly which features are fitted on the specific truck you’re considering.

Is now a good time to buy a used 2022 GMC Sierra 2500HD?

This is a moderate market for selective buyers, so it makes sense to compare listings carefully and move quickly on the right truck.

• Deal availability: 22.2% of listings are priced as good or great deals.

• Price trend: Prices have softened 5.99% compared with last year.

If you find a listing below $62,469 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2022 GMC Sierra 2500HD's resale value?

The current average of $63,460 CAD sits slightly below last year's $67,502 CAD.

That softer pricing suggests the market has become a bit more favourable for buyers, but it also means future sellers may need to be realistic about where their truck fits in the current range. If you buy well and keep the truck in strong condition, you may be better positioned when it’s time to resell. Trucks with desirable trims and strong equipment tend to hold attention longer, especially when they remain useful and well maintained.

Vehicles with solid owner satisfaction ratings, like this model year's 4.43/5, tend to retain buyer demand, which supports resale value over time.

Is the 2022 GMC Sierra 2500HD safe?

The 2022 GMC Sierra 2500HD is available with a wide range of driver-assistance features, including automatic emergency braking, forward-collision alert, lane-departure warning, lane-keeping assistance, blind-spot monitoring, rear cross-traffic warning, following distance indicator, hill-descent control, HD Surround Vision, a rear-seat reminder system, Safety Alert Seat, and front and rear park assist.

It earns an 8/10 safety score from our experts.

The Teen Driver system is standard, which is a useful feature if you plan to share the truck with newer drivers. Because the truck’s size and mass are such a big part of its safety story, the camera systems are especially valuable for visibility and manoeuvring.

Should I buy a 2022 GMC Sierra 2500HD or consider a different year?
