CarGurus Analysis: 2021 GMC Sierra 2500HD
Summary
With 76 currently listed for sale and an average price of $58,323 CAD, 35.5% of 2021 GMC Sierra 2500HD listings on CarGurus are rated as good or great deals.
Favourably reviewed: Owners rated the 2021 GMC Sierra 2500HD 5 / 5 stars.
Why it stands out
The 2021 GMC Sierra 2500HD stands out as a heavy-duty pickup that leans more upscale than many rivals, with a broader range of trim levels and upscale options than the related Chevrolet Silverado 2500HD. That positioning fits GMC’s “Professional Grade” image, and it helps the truck appeal to buyers who want a work-capable three-quarter-ton pickup without giving up on comfort or a more premium feel. It is also available in Canada in Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate trims, with Regular Cab, Crew Cab, and Double Cab body styles and 7-foot or 8-foot-2-inch cargo beds.
For 2021, the Sierra 2500HD offers a 6.6-litre V8 gas engine with a six-speed automatic transmission, and an available 6.6-litre Duramax turbodiesel V8 with a 10-speed automatic transmission from Allison. Rear- and four-wheel drive are available. The truck’s equipment list is a strength, with Bluetooth, Android Auto, Apple CarPlay, and Wi-Fi hotspot accessibility through the GMC infotainment system, plus available 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, while AT4 models bring off-road hardware such as skid plates, off-road suspension upgrades, and a more robust transfer case.
There are trade-offs to consider, though. Used fourth-generation Sierra 2500HD models are known for issues including check engine lights tied to diesel particulate filters or emissions sensors, sluggish infotainment responses, rough or delayed shifts, electrical glitches, MultiPro tailgate faults, and faulty trailer brake controllers. They also had very high MSRPs when new, so even used examples can be expensive.

-Excellent trailering mirrors with lights, allow increased visibility when backing up at night -Engine noise is relatively quiet compared to older diesel pick ups, can order at fast food drive throughs without shutting engine off -Fuel economy is good for a vehicle of this size (I have 3500HD, not 2500HD) -Driver safety features and various camera views are very helpful -Trim version for this review is Denali, with power running boards, really not missing anything significant

Is the 2021 GMC Sierra 2500HD a good car?
Yes — 5/5 is a strong user rating for the 2021 GMC Sierra 2500HD. The overview points to a heavy-duty pickup that leans more upscale than many rivals, with a broader range of trim levels and upscale options than the related Chevrolet Silverado 2500HD. That makes it a fit if you want a work-capable three-quarter-ton truck without giving up comfort or a more premium feel. 35.1% of listings are priced as good or great deals, which gives you some room to shop selectively.
Is the 2021 GMC Sierra 2500HD reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
The overview also notes that used fourth-generation Sierra 2500HD models can have issues such as check engine lights, infotainment sluggishness, rough or delayed shifts, electrical glitches, MultiPro tailgate faults, and faulty trailer brake controllers. For used buyers, that means reliability can depend heavily on maintenance history and a careful pre-purchase inspection.
Is now a good time to buy a used 2021 GMC Sierra 2500HD?
This is a moderate market for selective buyers, so you can shop with some leverage if you stay patient.

If you find a listing below $56,130 CAD, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2021 GMC Sierra 2500HD's resale value?
The current average of $58,100 CAD sits slightly below last year's $58,812 CAD.
That small decline suggests the market has eased a bit, which can help you buy more confidently now. For a future seller, it also means you should expect resale value to depend more on condition, trim, and equipment than on broad market momentum. Well-kept trucks with desirable features should still attract attention, especially in a segment where buyers often compare capability and comfort together.
Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2021 GMC Sierra 2500HD or consider a different year?
If you're weighing the 2021 against nearby model years, here's how to think about it:
Choose the 2021 if:
- 35.1% of listings are priced as good or great deals.
- Price trend: Prices have softened 1.21% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
Consider the 2022 if:
- At $60,440 CAD, the 2022 costs more than the current year's $58,100 CAD average.
- It broadens appeal by blending capability with more everyday comfort and technology.
The bottom line: Choose the 2021 if you want a premium-feeling heavy-duty truck and value a lower average price. If you can stretch your budget and want a newer alternative with broader appeal, the 2022 is the better upgrade path. For price-sensitive buyers, the 2021 remains the smarter buy when you find a well-priced example.
