CarComplaints.com Notes: The only area of real concern for 2011 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.
From a stop, the transmission did not engage on initial acceleration. This has happened twice, before fully warmed, and on cold days. In addition, on hard acceleration, shift from 1st to 2nd is "sloppy".
