Used 2024 GMC Sierra 2500HD for Sale near Brookdale, MB

How much does the 2024 GMC Sierra 2500HD cost?

Prices have softened 7.17% compared to this time last year, making it a favourable time to shop this model year.

There are 184 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 a 4.2/5 user rating and an 8/10 expert rating. The model scores 9/10 across Technology and Safety.

Owners consistently praise its impressive capabilities, professional-grade feel, and strong value. The overview also points to its upscale character and serious towing strength, which fits buyers who want a heavy-duty truck that feels more refined than a typical workhorse.

The trade-offs are clear: it can feel like overkill if you only need light towing, and the expert review notes that it is thirsty for fuel and cumbersome in tight parking situations. Even so, the market still shows 27.7% of listings as good or great deals, which keeps it appealing if you want maximum capability with luxury touches.

Is the 2024 GMC Sierra 2500HD reliable?

Owners rate it 4.2/5, a solid signal of long-term satisfaction.

The user review summary points to a truck that owners feel good about overall, with praise for its capabilities, impressive features, professional-grade character, and value. That same summary also highlights concerns around the gas engine’s reliability over time, especially carbon buildup issues.

The expert review reinforces the truck’s dependability in use, noting that the powertrain feels refined, the transmission does not hunt for gears, and the diesel setup delivers strong towing performance. It also mentions a diesel exhaust brake and heavy-duty hardware that support confident trailering.

For used buyers, the main long-term ownership risk is that a heavy-duty truck with complex diesel and trailering hardware can be costly to sort out if it has been worked hard or poorly maintained.

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

Key things to evaluate:

• Trim level: The Denali Ultimate is the top trim and brings nearly every available option, plus standard LED headlights and taillights, sequential turn signals, the MultiPro Tailgate, and the six-passenger Crew Cab. The base trims are much simpler, so you should check carefully which convenience and luxury features are included before you buy.
• Powertrain: The Denali Ultimate uses a 6.6-litre Duramax turbocharged diesel V8 with a 10-speed Allison automatic transmission and standard 4WD. It is tuned for serious towing and strong acceleration, but it is also a large, heavy-duty setup that is more truck than many shoppers need.
• Safety package: The truck includes 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 standard.
• Infotainment: The Denali Ultimate gets a 13.4-inch screen, wireless Apple CarPlay and Android Auto, wireless device charging, Google built-in, a 15-inch head-up display, and a 12-speaker Bose surround-sound system. You should also check that the screen layout and steering-column shifter placement work for you, since the stalk can block part of the display.
• Fuel efficiency: During long highway stints, the diesel dipped as low as 11.2 litres per 100 kilometres, while suburban and city driving could climb 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, so it makes sense if you want the Sierra HD nameplate at the lowest starting point and plan to keep the truck focused on work rather than luxury.
• SLE: This is the better-value choice if you want a step up from the most basic trim without chasing the highest price tags.
• SLT: This is the trim to consider if you want a more polished daily-driving experience and are willing to pay for extra comfort and convenience.
• AT4: This is the right pick if you want the off-road-oriented hardware and standard 4WD that come with the rugged side of the lineup.
• Denali: This is the luxury-leaning choice if you want a premium cabin without going all the way to the top.
• AT4X: This is the more upgraded off-road trim if you want the tougher, more specialised version of the AT4 formula.
• Denali Ultimate: This is the best-value trim if you want the most complete version of the truck, because it sits at the top of the range and bundles nearly every available option.

The safety package note is straightforward: from AT4 up, 4WD is standard, and the Denali Ultimate adds the fullest safety and driver-assistance equipment set.

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

This is a moderate market for selective buyers, so you can shop carefully without feeling rushed.

• Deal availability: 27.7% of listings are priced as good or great deals.
• Inventory: There are 184 listings available.
• Price trend: Prices have softened 7.17% 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 $78,892 CAD sits slightly below last year's $84,988 CAD.

That price movement suggests the market has cooled a bit, which can make the truck easier to buy now but slightly less favourable for a future seller. If you own one, softer pricing means you may need to be more patient to get top dollar, especially if your truck is not especially well equipped or has higher mileage.

On the other hand, the Sierra 2500HD’s strong capability and premium positioning help support demand among buyers who specifically want a heavy-duty truck with luxury touches. Well-kept examples should still hold attention better than more ordinary work trucks.

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 Top Safety Pick recognition from IIHS and five-star ratings from NHTSA.

It earns a 9/10 safety score from our experts.

The truck comes standard with automatic emergency braking, forward collision warning, pedestrian detection, and lane departure warning. On the Denali Ultimate, you also get 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.

That said, the safety story is strongest on the higher trim, since several of the more advanced driver-assistance features are optional on lesser versions. If safety tech matters to you, you should prioritise a well-equipped trim rather than assuming every Sierra HD has the same equipment.

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:

• 27.7% of listings are priced as good or great deals.
• Price trend: Prices have softened 7.17% compared with last year.
• Owners rate it 4.2/5 — a solid satisfaction signal.
• The 2024 model year adds the newly available Denali Ultimate trim, which sits at the top of the range and brings nearly every available option.

The bottom line: If you want the most luxurious and fully equipped version of the Sierra 2500HD, the 2024 is the year to target. If you are more price-sensitive, you may want to focus on lower trims or shop carefully for a well-priced used example rather than paying for the top-spec Denali Ultimate.
