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 the right car.

• Deal availability: 31.0% of listings are priced as good or great deals.
• Inventory: There are 1,437 listings available.
• Price trend: Prices have softened 7.35% compared with last year.

What is the 2021 Hyundai Sonata's resale value?

The current average of $17,123 sits slightly below last year's $18,481.

That softer pricing suggests the market has become more favorable for buyers, but it also means a future seller may need to be realistic about expectations. If you buy well now, you may have less depreciation pressure than someone who paid closer to last year’s average. The Sonata’s strong equipment level and broad appeal should help support demand, especially for well-kept examples with desirable features.

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 N Line earns strong marks from our experts for safety, and it comes with Hyundai’s SmartSense collection of advanced driver-assistance systems.

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

The standard feature set includes adaptive cruise control with stop-and-go, forward-collision warning with pedestrian and cyclist detection, automatic emergency braking, lane-departure warning, lane-keeping assistance, lane-centering 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.

One caveat is that the review notes the NHTSA had not carried over the standard Sonata’s frontal-impact ratings to the N Line at the time, and IIHS had not yet assigned a rating to this version. That means you should lean heavily on the ADAS equipment and a careful inspection history when evaluating a used example.

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:

• 31.0% of listings are priced as good or great deals.
• At 71.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.35% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.
• The N Line delivers a bargain-priced, enthusiast-friendly midsize sedan with strong performance and practicality.

Consider the 2022 if:

• At $19,670, the 2022 costs more than the current year's $17,123 average.
• It leans harder into value, quality, and a quiet cabin while keeping the Sonata’s strong warranty and safety appeal.

The bottom line: If you want the better price today, the 2021 is the smarter buy, especially if you can find a clean, well-equipped example. If you’re willing to spend more for a newer model-year alternative, the 2022 is the path to consider for buyers who want a slightly fresher take on the same core strengths.
