One problem related to ball joint has been reported for the 2009 Mazda CX9. The most recently reported issues are listed below.
I received a notice that water may enter the front suspension lower arm ball joint fittings during driving. Nothing has happened since receiving a notice in September 2015. They said parts are not available and they will notify me when they are available.
