While not a widespread complaint, the 2.5L turbocharged engine can experience issues with the turbocharger, potentially leading to reduced power or oil leaks. This is more common in vehicles with higher mileage that have not had consistent maintenance. Estimated repair cost: $1,500 - $3,000.

Infotainment System Glitches

Some owners report occasional glitches or unresponsiveness with the infotainment system. These are often software-related and can sometimes be resolved with dealer updates. Estimated repair cost: $100 - $500 (Software update or component replacement).

Carbon Buildup on Intake Valves

Direct-injection engines, like the one in the CX-9, are prone to carbon buildup on intake valves over time. This can affect engine performance and efficiency. Regular maintenance and occasional professional cleaning are recommended. Estimated repair cost: $400 - $800.
