Summary

Favourably reviewed: Owners rated the 2020 GMC Sierra 2500HD 4.86 / 5 stars.
100.0% of 2020 Sierra 2500HD models on CarGurus are accident free.
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 more trim levels and a wider range of upscale options and features than the related Chevy Silverado 2500HD, and the Denali and Denali Ultimate trims were described as more luxurious than the Silverado’s top-tier High Country trim. That makes the Sierra 2500HD especially appealing to buyers who want serious truck capability without giving up a more premium cabin experience.
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, and the truck could be had in Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate trims, 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.
The 2020 Sierra 2500HD also benefited from a broad list of convenience and technology features, including Bluetooth, Android Auto, Apple CarPlay, and Wi-Fi hotspot accessibility. Available equipment included remote keyless entry and rear-seat reminders, while more upscale models could be fitted with 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, buyers should be aware that these trucks had very high MSRPs when new, and used examples can still be expensive. The generation is also known for issues such as check engine lights, infotainment sluggishness, rough or delayed shifts, electrical glitches, MultiPro tailgate faults, and trailer brake controller problems.

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!!

Is the 2020 GMC Sierra 2500HD a good car?
Yes — owners rate it 4.86/5, which points to strong overall satisfaction. In owner feedback, the biggest positives are its performance, comfort, and towing capability, along with the power and appealing features that make it feel more premium than many heavy-duty rivals. That fits especially well if you want serious truck capability without giving up a more upscale cabin experience. With 32.7% of listings marked as good or great deals, you have a decent chance of finding a competitive example.
Is the 2020 GMC Sierra 2500HD reliable?
Owners rate it 4.86/5, a strong signal of long-term satisfaction.
Owner feedback also points to a truck that many people feel they can count on for performance and towing, with dependable capability being part of its appeal. That said, used buyers should still budget for careful inspection because heavy-duty trucks can carry expensive repair risk if prior use or maintenance history is unclear.
Is now a good time to buy a used 2020 GMC Sierra 2500HD?
This is a moderate, selective buyer’s market, so you can shop with some leverage if you are patient and focused.
- Deal availability: 32.7% of listings are priced as good or great deals.
- Inventory: There are 52 listings available.
- Price trend: Prices have softened 4.99% compared with last year.
If you find a listing below $53,181 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 $55,001 CAD sits slightly below last year's $57,890 CAD.
That decline suggests the market has eased a bit, which can help you buy more selectively today but may also mean future resale gains are limited if prices continue to soften. For a future seller, the current trend points to a truck that still holds meaningful value, but not one that is appreciating. Strong demand from shoppers who want heavy-duty capability and a more premium cabin should help support pricing better than a more basic work truck.
Vehicles with strong owner satisfaction ratings, like this model year's 4.86/5, 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:
- 32.7% of listings are priced as good or great deals.
- Price trend: Prices have softened 4.99% compared with last year.
- Owners rate it 4.86/5 — a strong satisfaction signal.
The bottom line: The 2020 is a strong choice if you want heavy-duty capability with a more premium feel and you can find a well-priced example. If you are shopping mainly on value, a nearby year may be worth comparing, but the 2020 makes the most sense when comfort, towing confidence, and owner satisfaction matter as much as price.
