CarComplaints.com Notes: The only area of real concern for 2012 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 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.
I have had this car in the shop on 2 occasions when under warranty for this vibration. Dealer could not replicate this and now with 67,000 miles (Out of warranty) I am stuck with a car I don't trust. I have sent letters and email to Mazda but have not heard anything yet. I am calling my local dealer to see if they can help.
I have seen this on other on-line discussions and it seems to be a torque/transmission issue.
GREAT! I have other cars much older..never expected to have a transmission issue which I think started at 45K miles......
