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 window regulators failed, the door locks failed, the door handles failed, the radio aux connection failed and it took 4 tries for them to figure out (it was electrical of course) and now the Bluetooth module has failed. .
Mazda has known since 2009 about the Bluetooth issue but will not replace the faulty part.
