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

Key things to evaluate:

• Trim level: The N Line treatment adds gloss black exterior accents, 19-inch alloy wheels, 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 and best-equipped version, this is the one to prioritise.
• Powertrain: You get a turbocharged 2.5-litre four-cylinder with 290 horsepower and 311 pound-feet of torque, paired with an eight-speed wet dual-clutch automatic transmission with paddle shifters, rev-matching, and launch control. It is tuned for strong on-road performance rather than relaxed commuting alone.
• 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. These features are standard on the N Line.
• Infotainment: The cabin uses a 12.3-inch digital instrument panel and a 10.25-inch touchscreen, with standard navigation, wireless smartphone charging, Bose audio, HD Radio, SiriusXM, 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 in combined driving, 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:

The N Line is the clear choice if you want the Sonata’s most performance-focused setup, with the turbocharged 2.5-litre engine, dual-clutch transmission, sport suspension, upgraded brakes, and the most complete feature set. It suits you best if you want a sedan that feels genuinely quick and more engaging than the average family car, while still keeping everyday practicality. The safety package is standard on this trim, so you do not need to climb the range to get the full ADAS suite.

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 patiently but still move quickly on a strong listing.

• Deal availability: 36.3% of listings are priced as good or great deals.
• Inventory: There are 113 listings available.
• Price trend: Prices have softened 17.22% compared with last year.

If you find a listing below $19,098 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 $19,147 CAD sits slightly below last year's $23,131 CAD.

That price drop suggests the market has already adjusted downward, which can help you as a buyer today but may temper resale expectations later. If you buy at a strong price, you reduce the risk of taking a bigger depreciation hit than necessary. The Sonata’s value story is still helped by its strong equipment level and broad appeal to shoppers who want style and practicality together.

Vehicles with strong owner satisfaction ratings, like this model year's 4.75/5, 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 capability, 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 described as exceptionally sophisticated and smooth in operation, which should make it easy to live with day to day.

One caveat is that the N Line had not been independently crash-tested as published, so the safety picture leans heavily on the standard Sonata’s results and the breadth of its driver-assistance technology.

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:

• 36.3% of listings are priced as good or great deals.
• Price trend: Prices have softened 17.22% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.
• It adds a rare sport-sedan feel with a bargain-price performance focus.

Consider the 2022 if:

• At $22,310 CAD, the 2022 costs more than the current year's $19,147 CAD average.
• It broadens the Sonata’s appeal with tremendous value and a sporty N Line variant.

The bottom line: If you want the best mix of price, performance, and value, the 2021 is the smarter buy. If you are willing to spend more for a newer model year and a broader appeal, the 2022 is the better secondary path.
