The Mazda CX-9 is a mid-size, three-row crossover SUV. The CX-9 debuted in 2007 as Mazda's largest SUV, and the 2021 model year is part of the second generation, introduced in 2016. Key trims include Sport, Touring, Grand Touring, and Signature. Pricing typically ranged from around $34,000 to $48,000 when new. It stands out for its upscale interior, engaging driving dynamics, and attractive styling, making it a popular choice for families seeking a more premium SUV experience.
The Good

The 2021 CX-9 offers a responsive turbocharged engine for enjoyable performance. Its upscale interior and comfortable seats provide a refined experience. While not the most fuel-efficient, it balances power with reasonable economy. Mazda's reputation for reliability adds peace of mind, and the stylish design appeals to those seeking a family vehicle that doesn't compromise on aesthetics.

The Bad

The 2021 CX-9's third-row seating is somewhat cramped compared to some competitors, making it less ideal for adults on long trips. The infotainment system, while improved, isn't as intuitive as some rivals. Cargo space behind the third row is also limited. Potential buyers should inspect for turbocharger issues and ensure regular oil changes were performed, as these can impact long-term reliability.

Analysis

What Problems Does the 2021 Mazda CX-9 Have?

The 2021 Mazda CX-9 generally enjoys good reliability, but some owners have reported issues. Some common concerns include:
  • Turbocharger Issues: Some owners have reported turbocharger failures or premature wear, potentially linked to oil sludge build-up. Regular oil changes with high-quality synthetic oil are crucial.
  • Infotainment System Glitches: While Mazda updated the infotainment system, some users still report occasional glitches, freezing, or slow response times.
  • Paint Quality: Mazda's paint has been noted by some owners to be thinner and more prone to chipping than some competitors.
  • Brake Wear: Some owners have observed relatively rapid brake wear, possibly due to the vehicle's weight and driving style.


Recalls for the 2021 model year were generally limited but it's essential to check the NHTSA website for the most up-to-date recall information based on the VIN. Pre-purchase inspections are recommended, particularly checking for turbocharger health and ensuring all scheduled maintenance has been performed. Long-term reliability concerns are relatively minor compared to some competitors, but addressing potential issues early is vital.

How long will the 2021 Mazda CX-9 last?

With regular maintenance, a 2021 Mazda CX-9 can reasonably be expected to reach 150,000-200,000 miles or 10-13 years of service. Long-term durability depends heavily on consistent maintenance, especially oil changes to protect the turbocharger. Weaknesses over time may include suspension component wear, potential for minor electrical issues, and eventual replacement of items like water pumps and alternators. Rust can be a concern in areas with heavy road salt usage, so regular washing and undercoating are beneficial.

What Technology & Safety Features are Included?

The 2021 Mazda CX-9 comes standard with a suite of impressive tech and safety features. Standard features include:
  • Infotainment: A 7-inch or 9-inch (depending on trim) infotainment display with Mazda Connect, Apple CarPlay, and Android Auto.
  • Audio: A six-speaker audio system standard, with a 12-speaker Bose system available on higher trims.
  • Driver Assistance: Adaptive cruise control, lane departure warning, lane keep assist, blind-spot monitoring, rear cross-traffic alert, and automatic emergency braking.
  • Safety: Standard features include advanced airbags, stability control, traction control, and a rearview camera.


Optional features included a 360-degree view monitor, head-up display, and parking sensors. The 2021 Mazda CX-9 earned excellent crash-test ratings from both the NHTSA (National Highway Traffic Safety Administration) and the IIHS (Insurance Institute for Highway Safety), including a 5-star overall safety rating from NHTSA and a Top Safety Pick+ award from IIHS when equipped with specific headlights. The robust safety features and strong crash-test performance make it a safe choice for families.

How Does the 2021 Mazda CX-9 Compare to Other Sport Utility Vehicle?

The 2021 Mazda CX-9 competes with the Honda Pilot, Toyota Highlander, Kia Telluride, and Hyundai Palisade. In terms of performance, the CX-9 offers a more engaging driving experience than the Pilot and Highlander, but the Telluride and Palisade offer similar or slightly better performance.

Best 3 row suv that’s smooth and comfortable

My first 2021 Mazda CX-9 GT. One of the best 3 row suv out there. Very smooth and comfortable. Worth every buck. Would buy another when the time comes. Can’t wait for the next generation to come out!

NEEDED SECOND CAR, BOUGHT ONE THAT FIT THE BILL

MY MAZDA CX9 GRAND TOURING IS A VERY NICE CAR. GAS MILEAGE IS GOOD, THE CAR'S FEATURES ARE GREAT, AND IT IS COMFORTABLE TO DRIVE. I ESPECIALLY LIKE THE "HEADS UP DSIPLAY". HELP ME KEEP CLOSE TO OR AT THE SPEED LIMIT AND THE NAVIGATION DATA DISPLAYED ON IT IS EASIER TO FOLLOW THAN LOOKING AT THE NAV DISPALY ON DASHBOARD.

It’s a 3 row suv that drives like a sports car.

It’s beautiful. I have the grand touring and it’s worth every penny. It’s a little more expensive than a lot of 3rd row suvs but it’s worth it because the handling and the gas mileage is so good. It seriously feel like I’m driving a sports car.

Test of CX-9

Smart setup for driver. Well crafted and high end materials. Unfortunately the engine is too small, and the ‘cockpit’ felt cramped. I am a taller individual, and went with the Pilot. More space for driver.
