Mazda CX-9 2.5T (2020+): A Mechanic's Unfiltered Review

The Mazda CX-9 2.5T is a popular three-row crossover SUV, often appealing to families needing space but wanting something a bit more stylish than a minivan. Let's ditch the marketing fluff and get down to the nuts and bolts of this vehicle from a mechanic's perspective.

Real-World Fuel Consumption:

The EPA estimates are around 20 city / 26 highway. In reality, expect closer to 18-20 mpg in the city and 22-24 on the highway. Lead-footing it will drop those numbers significantly. Towing? Forget about those EPA numbers; expect a noticeable decrease, down to 15-17 mpg, depending on what you're hauling. It's not exactly a fuel sipper.

Common Problems:

While the CX-9 2.5T is generally reliable, a few issues pop up in the shop. The turbocharger wastegate actuator can be problematic, leading to reduced power and odd noises. The infotainment system can be glitchy, requiring software updates or even component replacement. Some owners report transmission shuddering, though this seems less prevalent in newer models. Regular maintenance, especially oil changes with the correct viscosity, is crucial to keeping the turbo healthy. Also, some owners complain about premature wear of the front brake pads.

Maintenance Costs:

Routine maintenance like oil changes will run you around $80-$120. Brake jobs are typically $300-$500 per axle. Tires, given the CX-9's size, can cost $800-$1200 for a set. The big one down the road is the timing chain. It's an interference engine, so if it breaks, you're looking at a catastrophic engine failure. While they generally last a long time, replacing it is a labor-intensive job costing upwards of $2,000.

Hidden Costs:

Nothing too crazy here. Mazda uses fairly standard parts, readily available from most parts stores. Make sure to use the recommended synthetic oil. Using conventional oil in a turbocharged engine is asking for trouble.

Overall Reliability:

It's a relatively reliable vehicle. However, it's not a Toyota or Honda. Regular maintenance is key. Neglect it, and you'll pay the price. It ranks about average in its class for reliability.

Total Cost of Ownership:

Expect to spend a decent amount on gas, regular maintenance, and the occasional repair. The CX-9 isn't a cheap car to own, but it's not outrageously expensive either. It falls in the mid-range for its class.

Resale Value:

Mazdas generally hold their value reasonably well, but not as well as some of their Japanese competitors. Expect decent resale, especially if you've kept up with maintenance and have a good service history. They sell reasonably quickly, provided they're priced competitively. The used car market fluctuates, so this can change.

Tips for Prospective Buyers:

Get a pre-purchase inspection from a trusted mechanic. Focus on the turbocharger system and transmission.
Check the service history for regular maintenance, especially oil changes.
Look for signs of neglect, like worn tires, dirty interior, etc.
If buying used, consider a certified pre-owned vehicle for added peace of mind.

Alternatives:

If you're looking for something with a bit more reliability and potentially lower running costs, consider the Toyota Highlander or Honda Pilot. If you prioritize performance, the Kia Telluride or Hyundai Palisade might be worth a look.

Conclusion:

The Mazda CX-9 2.5T is a stylish and capable SUV. It's not perfect, but it's a decent choice if you're looking for a three-row crossover. Just be prepared for the potential maintenance costs and fuel consumption. Do your research, get a pre-purchase inspection, and you should be fine.
