Is the 2021 RAM 2500 reliable?

Owners rate it 4.69/5, a strong signal of long-term satisfaction.

The owner feedback also points to a truck that feels dependable in daily use, with praise for its performance and the confidence that comes from strong power. Comments about the diesel engine’s efficiency and the truck’s overall value suggest buyers see it as a vehicle they can count on over time. For used buyers, the main long-term ownership risk is that heavy-duty trucks can be costly to maintain if prior use was hard or poorly documented.

If you find a listing below $50,351 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 RAM 2500's resale value?

The current average of $50,584 CAD sits slightly below last year's $56,308 CAD.

That decline suggests the market has become more favourable for buyers, but it also means future sellers may face more price pressure if the trend continues. If you buy at the current average, your resale outlook will depend heavily on condition, mileage, and how well the truck was maintained. Strong demand for well-kept heavy-duty pickups can still support values, especially when the truck has desirable equipment and a clean history.

Vehicles with strong owner satisfaction ratings, like this model year's 4.69/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2021 RAM 2500 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:

• 28.8% of listings are priced as good or great deals.
• Price trend: Prices have softened 10.17% compared with last year.
• Owners rate it 4.69/5 — a strong satisfaction signal.

Consider the 2020 if:

• At $42,705 CAD, the 2020 costs less than the current year's $50,584 CAD average.
• It emphasises top-grade luxury, technology, and capability.

The bottom line: Choose the 2021 if you want the newer pricing context and strong owner satisfaction in a heavy-duty truck that blends capability with a more refined cabin. If your priority is saving money upfront, the 2020 is the better secondary path, especially if you find one with the features and condition you want.
