Used 2021 Mazda CX-9 for SaleNationwide

How much does the 2021 Mazda CX-9 cost?

Prices have softened 11.12% compared to this time last year, making it a favourable time to shop this model year.

There are 146 listings available, which suggests a reasonable amount of inventory for shoppers comparing used CX-9s.

Is the 2021 Mazda CX-9 a good car?

Yes — the 2021 Mazda CX-9 earns a 4.5/5 user rating and a 7/10 expert rating. The standout strength is Safety at 9/10.

Owners consistently praise its smooth handling, reliability, and luxurious interior, and the CX-9’s polished driving feel fits well if you want a refined three-row SUV rather than a purely utilitarian family hauler. The overview also points to a premium-leaning package with style, technology, and safety working together, while the main compromises are more power and cargo space. With 28.8% of listings marked as good or great deals, there is still some room to shop selectively.

Is the 2021 Mazda CX-9 reliable?

Owners rate it 4.5/5, a strong signal of long-term satisfaction.

User feedback highlights reliability alongside smooth handling and a luxurious interior, which is a good sign if you want a used SUV you can count on. The CX-9’s powertrain is described as robust and smooth in everyday use, with strong low-rpm torque and a six-speed automatic that behaves flawlessly. Mazda also positions the CX-9 as a high-quality, comprehensively equipped SUV, which supports the case for dependable ownership.

For used buyers, the main long-term ownership risk is that the CX-9 can still feel a bit thirsty and less spacious than some rivals, so it may not suit every family’s needs.

What should I look for when buying a used 2021 Mazda CX-9?

Key things to evaluate:

• Trim level: The GS starts with 18-inch alloy wheels, while the GS-L moves to 20-inch wheels. Higher trims add more standard features, and the GT brings a meaningful safety upgrade with adaptive front lighting, a driver-attention monitor, front and rear parking sensors, reverse automatic emergency braking, and a surround-view camera system.
• Powertrain: Every CX-9 uses a 2.5-litre turbocharged four-cylinder engine with a six-speed automatic transmission. All-wheel drive is standard in Canada, and the engine delivers strong low-rpm torque with peak power arriving early.
• Safety package: Standard equipment includes blind-spot monitoring, rear cross-traffic alert, adaptive cruise control with stop-and-go capability, and rain-sensing wipers. The GT adds a driver-attention monitor, parking sensors, adaptive front lighting, reverse automatic emergency braking, and a surround-view camera system.
• Infotainment: You get Mazda Connect with a 10.25-inch static display, plus Apple CarPlay, Android Auto, Bluetooth, and text messaging support. The system still lacks a touchscreen, and voice recognition is a weak point.
• Fuel efficiency: Natural Resources Canada says the CX-9 is supposed to use 10.5 L/100 km combined, while testing returned 11.7 L/100 km.

Which 2021 Mazda CX-9 trim should I buy?

The 2021 Mazda CX-9 is offered in 5 trim levels: GS, GS-L, GT, Kuro Edition, and Signature.

Here's the short version:

• GS: This is the entry point, and it gives you the core CX-9 experience with standard all-wheel drive, the turbocharged engine, and the basic safety and infotainment setup. It makes sense if you want the lowest-cost way into the model.
• GS-L: This trim adds 20-inch wheels and sits as the next step up from the GS. It is the better-value choice if you want a little more presence without jumping too far up the range.
• GT: This is the trim to focus on if safety and convenience matter most, because it adds adaptive front lighting, a driver-attention monitor, parking sensors, reverse automatic emergency braking, and a surround-view camera system. It also brings satellite radio, a Bose sound system, a wireless phone charger, and a head-up display.
• Kuro Edition: This trim is part of the more luxurious upper end of the range, but the provided data does not separate it with unique equipment details beyond its place above the GT.
• Signature: This is the most upscale version, with premium Nappa leather, Santos Rosewood inlays, real aluminium accents, a restyled grille, fresh wheel design, and quilted leather with contrast piping. It suits you if you want the most premium CX-9 experience.

The GT is the key safety-package trim to target if you want the biggest equipment jump without going all the way to the top.

Is now a good time to buy a used 2021 Mazda CX-9?

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

• Deal availability: 28.8% of listings are priced as good or great deals.
• Inventory: There are 146 listings available.
• Price trend: Prices have softened 11.12% compared with last year.

If you find a listing below $27,646 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Mazda CX-9's resale value?

The current average of $27,649 CAD sits slightly below last year's $31,109 CAD.

That price movement suggests the CX-9 has already absorbed a meaningful amount of depreciation, which can be helpful if you are buying now and planning to sell later. For a future seller, the softer market means you may not recover as much as an earlier owner did, especially if the vehicle is priced above the current average. Even so, the CX-9’s premium feel and strong owner satisfaction can help support demand when it is time to list it.

Vehicles with strong owner satisfaction ratings, like this model year's 4.5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 Mazda CX-9 safe?

The 2021 Mazda CX-9 earns a Top Safety Pick+ rating from IIHS and a five-star overall rating from NHTSA, with four-star frontal-impact results for the driver and front passenger.

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

Standard safety equipment includes blind-spot monitoring, rear cross-traffic alert, adaptive cruise control with stop-and-go capability, and rain-sensing wipers. Mazda also includes lane-departure warning, lane-keep assist, and a forward-collision warning system that can trigger a bright BRAKE! warning on the HUD. The GT trim adds adaptive front lighting, a driver-attention monitor, front and rear parking sensors, reverse automatic emergency braking, and a surround-view camera system.

One caveat is that lane-centring assistance is unavailable, and the frontal-impact NHTSA results are less reassuring than the overall score.

Should I buy a 2021 Mazda CX-9 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 11.12% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.
• The 2021.5 updates add a standard 10.25-inch display and new safety features.

Consider the 2022 if:

• At $31,043 CAD, the 2022 costs more than the current year's $27,649 CAD average.
• It adds a more clearly defined five-trim Canadian lineup.

The bottom line: The 2021 is the better value if you want the CX-9’s premium feel at a lower price, especially with the 2021.5 updates already in place. If you are less price-sensitive and want the newer model year, the 2022 is the cleaner alternative.

How does the 2021 Mazda CX-9 compare to the 2021 Honda Pilot?

Our experts score the 2021 Mazda CX-9 7/10 and the 2021 Honda Pilot 7.2/10. The CX-9 is the more affordable option, with a lower average used price and a stronger share of good and great deals. The Pilot brings more listings and a stronger V6 on paper, while the CX-9 leans harder into premium feel, safety, and a more polished driving experience.
