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.

2013 Mazda CX-9 Owner Comments

CX-9 6-cyl

  • 338 miles


The voice activated navigation feature on the vehicle shuts down and becomes inoperable when stopping or accelorating from a stopped position. The voice activated feature only works while in one long continuous motion which defeats the purpose of the hands-free voice activated navigation and makes using the system difficult in urban environments. This concern was voiced to the local dealer and sales staff who could not figure out why the system was malfunctioning this way and advised that they were not able to fix it. No remedy was available and I am stuck with a vehicle that doesn't function as it was advertised to me and sold.
