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.

About These NHTSA Complaints:
This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The vehicle stalls when idling at a stop light or in a drive thru. The vehicles motor begins to shake and then eventually dies and stalls out and the vehicle must be started again with the turn of the ignition. The braking system is also defective. When at a stop light and your foot is on the brake pedal. The pedal suddenly sinks as if the brake fluid in the master cylinder has drained fully and the brake pedal sinks all the way to the floor and the vehicle shoots forward even if your foot is on the brake. Another problem is in the power door lock system. There has been a time when the power door lock was stuck and the rear right door could not be shut. I had to drive the car to the dealership with the car door flopping all over the place. They were able to fix it at the dealership but could not figure out how it occurred. They were as puzzled as I was. The car was bought back in 2010 brand new from the Mazda dealership. The reviews were good for the vehicle. Its the first Mazda we purchased and is probably going to be the last.
