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 contact owns a 2010 Mazda CX-9. The contact received notification of NHTSA campaign number 15V451000 (Suspension) however, the part to do the recall repair was unavailable.

Vehicle pulsates while braking while driving fast or at slower speeds. The steering wheel does not shake. The brake pedal does not pulsate. The vehicle brakes were changed several times with new rotors and pads on all four tires. I noticed there was a recall on lower control arms #15V-451. It only was inspected at the time of recall but never changed. Could it be possible that they are now worn and can be changed per the recall.
Control arm/ball joints- had to have replaced again on 9/21/18 after both being replaced on 1/12/2016 as part of a recall. Feels like the car is trying to steer itself and not very safe to drive. And then have to pay for another alignment which I just had done as well. There should be some type of warranty on a recall repair.
We took our 2010 Cx-9 with 99,000 miles the Mazda dealer in union NJ because of a noise in the car and were told that the rear subframe has rotted out and is destroying the rear diff mounting bolts. We were also told the exhaust system is also rotted out and the vehicle is unsafe to drive. If we go over a pot hole, the whole undercarriage of car can fall out. This car was not kept at the beach and well maintained.

Took my car to dealer 2-3 times for the brakes, way before my warranty was any where near expiring, because I kept hearing a grinding sound. They kept telling me nothing was wrong, that my brakes had some gravel on them and they just cleaned them. I don't travel on dirt roads or anything, city roads/highways. No out of town travel at all, actual only in town travel, home/work. My 2nd concern is, while driving sometimes my speed seems to shift, as if the gears are shifting. 3rd concern is, I received a recall notice, don't recall what it was about but I took it to the dealership and I was told they done that work last time I came in but I don't believe it was done, since they haven't been honest with me before. They didn't even look at the letter. If I recall correctly brake complaints/ service started 2011 or 2012 to 2014....
