What should I look for when buying a used 2021 Hyundai Sonata?

Key things to evaluate:

• Trim level: The N Line treatment adds a more aggressive exterior look, sport front seats with Nappa leather bolsters and Dinamica suede inserts, red stitching, aluminium pedal covers, dark chrome accents, and a panoramic sunroof. If you want the most distinctive version, this is the one to focus on.
• Powertrain: The N Line uses a turbocharged 2.5-litre four-cylinder engine with an eight-speed wet dual-clutch automatic transmission, paddle shifters, rev-matching, and launch control. It is tuned for stronger performance and sharper response than the standard Sonata.
• Safety package: Hyundai’s ADAS suite includes 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 system is comprehensive and smooth in use.
• Infotainment: You get a 12.3-inch digital instrumentation panel and a 10.25-inch touchscreen infotainment system, plus onboard navigation, wireless smartphone charging, Bose audio, HD Radio, SiriusXM satellite radio, Apple CarPlay, Android Auto, Bluetooth, and Blue Link connected services. It does not offer a WiFi hotspot.
• Fuel efficiency: Natural Resources Canada says the powertrain should use 8.8 L/100 km combined, with 10.1 L/100 km in the city and 7.2 L/100 km on the highway.

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:

• N Line: This is the only trim described here, and it is the best fit if you want the Sonata’s strongest performance, the most distinctive styling, and a full-featured equipment list. It adds the turbocharged 2.5-litre engine, dual-clutch transmission, sport suspension, upgraded brakes, and the most complete tech and safety package in the material provided.

The safety package is standard on this trim, so you do not need to step up to unlock the core driver-assistance features.

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 with some leverage if you’re patient.

• Deal availability: 25.5% of listings are priced as good or great deals.
• Inventory: There are 102 listings available.
• Price trend: Prices have softened 16.31% compared with last year.

If you find a listing below $18,807 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 $18,807 CAD sits slightly below last year's $22,472 CAD.

That price movement suggests the Sonata has already absorbed a meaningful amount of depreciation, which can help you as a buyer today. For a future seller, it means there may be less room for dramatic price drops if the car is kept in good condition and remains desirable in the used market.

The model’s strong owner satisfaction should help support demand when it’s time 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 2021 Hyundai Sonata earns a Top Safety Pick rating from IIHS on Limited trims with upgraded LED projector headlights.

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

Hyundai’s standard ADAS suite includes 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.

A key caveat is that the N Line had not been tested independently when this review was written, so the strongest crash-test result cited here applies to the standard Sonata rather than this specific version.

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:

• 25.5% of listings are priced as good or great deals.
• Price trend: Prices have softened 16.31% compared with last year.
• Owners rate it 4.8/5 — a strong satisfaction signal.
• The 2021 stands out for its sporty N Line focus, strong value, and comprehensive safety tech.

Consider the 2022 if:

• At $21,517 CAD, the 2022 costs more than the current year's $18,807 CAD average.
• It adds exceptional value and a surprisingly sporty N Line variant.

The bottom line: If you want the better bargain, the 2021 is the smarter starting point because it already offers strong value, solid owner satisfaction, and a lower average price. If you’re willing to spend more for a newer model year, the 2022 is worth a look for buyers who want the same basic appeal with a fresh-year alternative.

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