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.
We bought a Mazda CX-9 since my uncle needed one. But we didn't know while buying the car, the fuel gauge wasn't working well. Surely enough, we thought the gas filled up to 35%. The car soon halted on a bridge and we waited for help. We still don't have a solution for this and may cost a lot of money if this gets into something major.
