This recall applies only to vehicles equipped with Takata-brand air bag inflators. Upon deployment the passenger airbag inflator could rupture, increasing the risk of personal injury. Mazda dealers will replace the affected airbag inflator modules to correct this concern.
The front lower control arms may break at the hanger brackets due to corrosion. This corrosion is commonly a result of the hanger bracket being exposed to salty conditions, such as roads where salt is used as a snow melting agent. A broken control arm can result in loss of vehicle control, increasing the risk of a crash. Dealers will inspect the affected control arms and rustproof or replace them as necessary. The Subaru recall number is WVX-34.
