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.

I am 81 years old and intended for this 2010 CX9 Mazda to last me the rest of my life. Knew nothing about the hidden water pump problem. The overheating first occurred when my wife and I were driving in the parking lot of a strip shopping center. The radiator fans came on as we were parking. The heat gauge was hotter than normal but never maxed out. Left for home and discovered that the antifreeze coolant had leaked into the motor oil. Knew immediately that something major had happened. After determining that the necessary repairs would exceed appraised value of my vehicle, I purchased another vehicle not a Mazda. I guess my Mazada sitting in my yard will have to be sold for junk. Such a terrible ending to a vehicle that I had truly enjoyed.
MAZDA NEEDS TO STEP-UP AND DO THE RIGHT THING!
