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.
2010 Mazda cx9 GT - purchased new in November 2010 - 97000 Kms and my rack and pinion needs replaced. $1800 fix I'm told by my dealer - this of course is not covered under warranty...should be... But not. Absolutely no reason for this to go. Will be interesting to see if more CX-9 owners have experienced the same issue. Not a happy customer. Most likely the last Mazda product I will own.
