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.

Noticed dashboard on the passenger side was melting. Driver side is ok, but that's because in the 2010 Mazda 6 I sport models, at least, the dashboard is made of two different materials between driver side and passenger side. If you put your finger on the melted area, there will be a black tar-like residue on your finger when you take it off. This is a black dashboard. No safety issue that I'm aware of, but there is no excuse for a dashboard to melt, regardless of climate that the car is in.
