Air bags:frontal:passenger side:inflator module

Mazda North American Operations (Mazda) is recalling certain 2007-2012 CX-7, CX-9, and 2009-2012 Maza6 vehicles. These vehicles had their passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.

An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.

These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules, and used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the front air bags, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.

An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death.

15V451000 2015-07-20
Suspension:front:control arm:lower ball joint

Mazda North American Operations (Mazda) is recalling certain model year 2007-2014 CX-9 vehicles manufactured October 24, 2006, to December 28, 2013. The affected vehicles have front suspension ball joints that may corrode from water leaking into the fitting.

Over time, the ball joint corrosion may result in the front lower control arm separating from the ball joint, causing a loss of steering control and increasing the risk of a crash.

UPON LIGHT BRAKING I HEAR A HISSING SOUND. THE BRAKES ARE INEFFECTIVE AT SLOW SPEEDS. IT TAKES A LONGER TIME AND REQUIRES APPLICATION OF GREATER BRAKING FORCE TO GET THE CAR TO COME TO A COMPLETE STOP. I TOOK THE CAR IN FOR INSPECTION AND AM AWAITING THE RESULTS. I SAW ONLINE THAT THERE ARE KNOWN PROBLEMS WITH THE BRAKING SYSTEM. *TR
