CarGurus Analysis: 2020 GMC Sierra 2500HD

Summary
With 50 currently listed for sale and an average price of $54,970 CAD, 32% of 2020 GMC Sierra 2500HD listings on CarGurus are rated as good or great deals.
Favourably reviewed: Owners rated the 2020 GMC Sierra 2500HD 4.9 / 5 stars.
Why it stands out
The 2020 GMC Sierra 2500HD stands out as a heavy-duty pickup that leans more upscale than many rivals. In this generation, GMC offered it in more trim levels than the related Chevrolet Silverado 2500HD, with a wider range of upscale options and features, and the Denali and Denali Ultimate trims were described as more luxurious than the Silverado’s top-tier High Country trim. That positioning gives the Sierra 2500HD a more premium feel for buyers who want serious truck capability without giving up comfort and refinement.
For 2020, the Sierra 2500HD came with a 6.6-litre V8 gas engine paired with a six-speed automatic transmission, and it was also available with a 6.6-litre Duramax turbodiesel V8 engine and a 10-speed automatic transmission from Allison. Rear- and four-wheel drive were available. The truck was offered in Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate trim levels, with Regular Cab, Crew Cab, and Double Cab body styles and 7' or 8'2" cargo bed options. The AT4 models added off-road hardware and accessories such as skid plates, off-road suspension upgrades, and a more robust transfer case, while the Denali trims added luxury cabin features.
Equipment is another strength. The 2020 Sierra 2500HD could be had with Bluetooth, Android Auto, Apple CarPlay, and Wi-Fi hotspot accessibility through the GMC infotainment system, and available features included remote keyless entry and rear-seat reminders. Higher-end versions could add a Bose premium audio system, power-adjustable front seats, chrome grille trim, dual-zone automatic climate control, and power-folding tailgate options. At the same time, used shoppers should be aware that this generation has a long list of reported problems, including check engine lights, infotainment sluggishness, rough or delayed shifts, electrical glitches, MultiPro tailgate faults, and faulty trailer brake controllers. It can also be expensive on the used market, especially in higher trims.

Looks great but a little pricey for the year. Even though it has low mileage. I would buy a newer truck.

The GMC 2500 HD is the truck for me. Like all the other major brands of trucks the price is in the same range. The diesel engine and 4x4 is about good as it gets. For work or play GMC is the way!!

How much does the 2020 GMC Sierra 2500HD cost?
| Metric | Value |
|---|---|
| Current Average Price | $54,744 CAD |
| Year-Round Low | $53,247 CAD |
| Year-Round High | $59,876 CAD |
| Average Price a Year Ago | $55,513 CAD |
| Change vs. Last Year | −1.38% |
Prices have softened 1.38% compared to this time last year, making it a favourable time to shop this model year.
There are 50 listings available, which gives you a modest amount of inventory to compare.
Is the 2020 GMC Sierra 2500HD a good car?
Yes — the 2020 GMC Sierra 2500HD earns a 4.9/5 user rating, which points to strong owner satisfaction. Owners consistently praise its performance, comfort, and towing capabilities, and many also highlight its power and appealing features. For you, that makes it a strong fit if you want a heavy-duty pickup that still feels more upscale and refined than many rivals. With 32% of listings marked as good or great deals, there is still some room to shop carefully.
Is the 2020 GMC Sierra 2500HD reliable?
Owners rate it 4.9/5, a strong signal of long-term satisfaction.
The owner feedback points to a truck that many people feel good about living with over time, especially for performance and towing. That said, used buyers should still weigh the reported problem history carefully, because long-term ownership risk can rise if you end up with a truck that has unresolved electrical, transmission, or equipment issues.
Is now a good time to buy a used 2020 GMC Sierra 2500HD?
This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you are patient and compare listings closely.
- Deal availability: 32% of listings are priced as good or great deals.
- Inventory: There are 50 listings available.
- Price trend: Prices have softened 1.38% compared with last year.
If you find a listing below $53,247 CAD, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2020 GMC Sierra 2500HD's resale value?
The current average of $54,744 CAD sits slightly below last year's $55,513 CAD.
That kind of softening suggests the market has eased a bit, which can help you buy more confidently today but may also limit short-term upside if you plan to resell soon. If you are thinking about future value, the current pricing trend implies that a well-kept truck bought at the right price should be easier to move later than one purchased at the top of the range. Strong demand for capable heavy-duty pickups can help support resale, especially when the truck has the features and condition buyers want.
Vehicles with strong owner satisfaction ratings, like this model year's 4.9/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2020 GMC Sierra 2500HD or consider a different year?
If you're weighing the 2020 against nearby model years, here's how to think about it:
Choose the 2020 if:
- 32% of listings are priced as good or great deals.
- Price trend: Prices have softened 1.38% compared with last year.
- Owners rate it 4.9/5 — a strong satisfaction signal.
The bottom line: The 2020 makes sense if you want a heavy-duty truck with strong owner approval and you can find one priced near the lower end of the market. If you are especially price-sensitive, a nearby year may be worth a look, but the 2020 is the better fit when you want a more premium-feeling Sierra 2500HD and are willing to shop selectively for value.
How does the 2020 GMC Sierra 2500HD compare to the 2020 Ford F-250 Super Duty?
| Spec | 2020 GMC Sierra 2500HD | 2020 Ford F-250 Super Duty |
|---|---|---|
| Average used price | $54,744 CAD | $43,492 CAD |
| Listings available | 50 | 81 |
| Good & great deal share | 32% | 21.0% |
