CarComplaints.com Notes: The only area of real concern for 2013 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 for most affected CX-9 owners, 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.

When I use my remote to open my liftgate it goes up 3/4 way and just drops. I was getting groceries out of my trunk area and had to move quickly as it suddenly came down. After calling Mazda I was informed of a recall but my car VIN wasn't included in the recall. It seems the same incident has been happening on other Mazda vehicles. Vehicle was stationary in my driveway turned off and parked.

Lost control of vehicle coming down a ramp in a parking garage, causing me to strike pole in garage, or would have careened over 6th fl railing down 6 stories to street. Vehicle in motion.
