CarComplaints.com Notes: The only area of real concern for 2010 Mazda CX-9 owners is the brake booster.
In 2014, Mazda extended the warranty on the 2007-2013 CX-9 brake booster to 7 years / 90,000 miles. However this extended warranty has expired, so buyer beware.
This Mazda CX-9 brake booster failure isn't terrible in terms of repair cost — it "only" costs $550 average to fix. However it is a safety issue when the brake booster fails as it increases stopping distance. Owners have reported having to stomp on the brake pedal, & crashes/injuries have been reported due to this CX-9 brake booster defect.

The engine light came on. Called dealer, Mazda of Turnersville, NJ they stated ok to drive as long as light is not blinking. I has never blinked. I had the car towed to the dealer, three days later I heard from them. (856-393-5808 or 856-875-0200), spoke on the phone and in person with the service manager. He offered no solution. I have called Mazda the toll free number twice.
Friday 4-23 spoke with a girl in customer service named Shenoa, explained the issue. We have been a customer of theirs for over 20 years (3) separate vehicles, had to replace the transmission on the Tribute, did not ask Mazda for help. My car has 107,000 miles now and I am getting costs on replacing it used and new. Still waiting to hear back from my mechanic. I spoke with the service manager on Friday, 4-23 he offered no help and was not a very nice guy.
Mazda has 100% service both my tribute and CX9 and can provide records if needed. This care was schedules for routine service today, 4-26. The internet provide me with the issues with this car. They put the water pump inside the engine. There would never be a warning with their design. I had no warning. The dealer told me on 4-22-2021 what had happened. Water pump failed and the water went into the engine . I asked the service manager about when they would let me know about this design defect and the water pump. He said they would not have let us know.
