Which 2021 Hyundai Sonata trim should I buy?

The 2021 Hyundai Sonata is offered in 1 trim level: N Line.

Here's the short version:

The N Line: is the one to choose if you want the Sonata at its most engaging. It adds the turbocharged 2.5-litre engine, the dual-clutch transmission, sport-tuned hardware, and the most distinctive exterior and interior treatment.

Is now a good time to buy a used 2021 Hyundai Sonata?

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile listings.

• Deal availability: 36.5% of listings are priced as good or great deals.
• Inventory: There are 104 listings available.
• Price trend: Prices have softened 14.43% compared with last year.

If you find a listing below $18,797 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Hyundai Sonata's resale value?

The current average of $18,861 CAD sits slightly below last year's $22,041 CAD.

That decline suggests the market has already adjusted downward, which can make the car more attractive to used buyers today. For a future seller, it also means you should expect resale value to depend heavily on condition, mileage, and how well the car is equipped.

Because the model still has meaningful buyer appeal, well-kept examples should remain easier to move than less distinctive sedans. Strong value positioning can help support demand, but the softer pricing trend means you may need to price competitively when it’s your turn to sell.

Vehicles with strong owner satisfaction ratings, like this model year's 4.8/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 Hyundai Sonata safe?

The Sonata rates high for occupant protection in a collision.

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

Hyundai’s standard ADAS package is broad and well rounded, with adaptive cruise control with stop-and-go, forward-collision warning with pedestrian and cyclist detection, automatic emergency braking, lane-departure warning, lane-keeping assist, lane-centring assistance, blind-spot warning, rear cross-traffic warning, driver-attention warning, automatic high-beam headlights, Rear Occupant Alert, Safe Exit Warning, and Highway Drive Assist.

The main caveat is that the N Line had not been tested independently as this review was written, so the safety assessment leans on the standard Sonata’s crash performance and the comprehensiveness of the driver-assistance suite.

Should I buy a 2021 Hyundai Sonata 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:

• 36.5% of listings are priced as good or great deals.
• Price trend: Prices have softened 14.43% compared with last year.
• Owners rate it 4.8/5 — a strong satisfaction signal.
• The 2021 stands out for its sporty N Line character, strong value, and broad standard safety tech.

Consider the 2022 if:

• At $21,277 CAD, the 2022 costs more than the current year's $18,861 CAD average.
• It leans harder into tremendous value and exceptional quality.

The bottom line: If you want the better price today, the 2021 is the smarter starting point. If you’re willing to spend more for a newer model-year perspective, the 2022 is worth a look, but price-sensitive buyers should focus on the 2021’s softer market and stronger deal availability.

How does the 2021 Hyundai Sonata compare to the 2021 Kia K5?

The Sonata comes out ahead on expert score and value, while the K5 asks more money on the used market.
