Used 2024 GMC Sierra 2500HD for Sale nearThunder Bay, ON

How much does the 2024 GMC Sierra 2500HD cost?

Prices have softened 7.44% compared to this time last year, making it a favourable time to shop this model year.

There are 185 listings available, which suggests you still have some room to compare trims and prices.

Is the 2024 GMC Sierra 2500HD a good car?

Generally — the 2024 GMC Sierra 2500HD earns 4.2/5 from owners and 8/10 from experts. The model scores 9/10 across Technology and Safety.

Owners consistently praise its professional-grade feel, impressive features, and strong value. The overview also points to a truck that blends serious capability with a distinctly upscale feel, especially if you want maximum towing strength and a more luxurious cabin than a typical work truck provides.

The main trade-offs are that it can feel like overkill if you only need to tow something modest, and the truck’s size makes it less convenient in tight spaces. The expert test drive also notes a thirst for fuel and a barge-like feel when parking.

With 30.8% of listings marked as good or great deals, the market still offers some room for value shopping.

Is the 2024 GMC Sierra 2500HD reliable?

Owners rate it 4.2/5, a solid signal of long-term satisfaction. The owner summary also points to a truck that feels capable and dependable, with buyers appreciating its professional-grade character and value.

The expert drive notes a powertrain that feels refined and confident, with the transmission never hunting for the right gear and the diesel delivering strong, smooth acceleration. That kind of composure matters in a heavy-duty truck you may plan to keep for years.

The main long-term ownership risk for used buyers is that heavy-duty trucks can be expensive to maintain if they’ve been worked hard, so service history and careful inspection matter more than mileage alone.

What should I look for when buying a used 2024 GMC Sierra 2500HD?

Key things to evaluate:

• Trim level: The Denali Ultimate adds the most luxury and convenience, including standard LED lighting, sequential turn signals, the MultiPro Tailgate, and a six-passenger Crew Cab layout. Lower trims do not get the same upscale cabin treatment or the full standard equipment set.
• Powertrain: The Denali Ultimate uses a 6.6-litre Duramax turbocharged diesel V8 with 470 horsepower and 975 lb-ft of torque, paired with a 10-speed Allison automatic transmission and standard 4WD. It also includes a locking rear differential, two-speed transfer case, all-terrain tyres, heavy-duty air filter, underbody skid plates, hill descent control, and a diesel exhaust brake.
• Safety package: GMC’s driver-assistance suite includes automatic emergency braking, forward collision warning, pedestrian detection, lane departure warning, front and rear parking sensors, a surround-view parking camera, adaptive cruise control, rear cross-traffic alert, blind-spot monitoring, and a rear-facing cargo bed camera. On the Denali Ultimate, these features are standard.
• Infotainment: The Denali Ultimate gets a 13.4-inch touchscreen, a 15-inch multi-colour head-up display, wireless Apple CarPlay and Android Auto, wireless device charging, Google built-in, a 12-speaker Bose surround-sound system, and split-screen navigation.
• Fuel efficiency: During long highway stints, the diesel dipped as low as 11.2 litres per 100 kilometres, while suburban and city driving routinely climbed well beyond 20 L/100 km.

Which 2024 GMC Sierra 2500HD trim should I buy?

The 2024 GMC Sierra 2500HD is offered in 7 trim levels: Pro, SLE, SLT, AT4, Denali, AT4X, and Denali Ultimate.

Here's the short version:

• Pro: This is the entry point if you want the Sierra HD nameplate at the lowest cost, but it is the most basic route into the lineup.
• SLE: This is the first step up if you want a more usable everyday truck without jumping straight to the luxury end of the range.
• SLT: This is the better-value choice for many shoppers because it moves you closer to the upscale feel of the higher trims without going all the way to Denali pricing.
• AT4: Choose this if you want the off-road-oriented setup and standard 4WD from this trim upward.
• Denali: This is the luxury-focused pick if you want a more premium cabin and a stronger feature set.
• AT4X: This is the more rugged off-road trim if you want the upgraded off-road hardware and a more specialised setup.
• Denali Ultimate: This is the top trim and the one to buy if you want nearly every available feature, the most luxurious cabin, and the strongest “work-meets-luxury” appeal.

The safety package is standard on the Denali Ultimate, while some of the same driver-assistance features are optional on lower trims.

Is now a good time to buy a used 2024 GMC Sierra 2500HD?

This is a moderate, selective-buyer market, so you can still find value if you shop carefully.

• Deal availability: 30.8% of listings are priced as good or great deals.
• Inventory: There are 185 listings available.
• Price trend: Prices have softened 7.44% compared with last year.

If you find a listing below $76,762 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2024 GMC Sierra 2500HD's resale value?

The current average of $79,143 CAD sits slightly below last year's $85,508 CAD.

That softer pricing suggests future sellers may not see the same strength they would have a year ago, especially if the truck is heavily optioned or has higher operating costs. Still, the current market shows that buyers continue to value this model’s capability and upscale presentation.

If you keep the truck well maintained and present it with strong service records, you should be in a better position when it comes time to sell. Heavy-duty trucks with premium trims can hold attention, but condition and configuration will matter a lot.

Vehicles with solid owner satisfaction ratings, like this model year's 4.2/5, tend to retain buyer demand, which supports resale value over time.

Is the 2024 GMC Sierra 2500HD safe?

The 2024 GMC Sierra 2500HD earns a 9/10 safety score from our experts.

It comes standard with automatic emergency braking, forward collision warning, pedestrian detection, and lane departure warning. On the Denali Ultimate, front and rear parking sensors, a surround-view parking camera, adaptive cruise control, rear cross-traffic alert, blind-spot monitoring, and a rear-facing cargo bed camera are all standard as well.

That said, some of the more advanced driver-assistance features are optional on lower trims, so you should verify equipment carefully if you are shopping outside the Denali Ultimate. The large power-operated side mirrors also help visibility, which is useful in a truck this size.

Should I buy a 2024 GMC Sierra 2500HD or consider a different year?

If you're weighing the 2024 against nearby model years, here's how to think about it:

Choose the 2024 if:

• 30.8% of listings are priced as good or great deals.
• Price trend: Prices have softened 7.44% compared with last year.
• Owners rate it 4.2/5 — a solid satisfaction signal.
• The Denali Ultimate is newly added for 2024 and brings nearly every available option, along with a 6.6-litre Duramax diesel V8 and a maximum towing capacity of 10,200 kilograms.

The bottom line: If you want the most luxurious and most fully equipped version of this heavy-duty truck, the 2024 is the one to target. If your priority is simply getting into a Sierra HD at a lower price, a less expensive trim may make more sense, especially if you do not need the Denali Ultimate’s full feature set.
