In response to the Takata airbag inflator recall that affects an estimated 10 million cars, Subaru (FUJHY) has recalled as many as 500,000 vehicle models because they may have a frontal airbag inflator that could explode.

The airbag inflators may have a seal issue that allows moisture to degrade the propellant, causing them to explode and send shrapnel into the vehicle, which could injure or kill the occupants.

The recall affects 2009 to 2013 Forester, 2003 to 2006 Baja, 2004 to 2011 Impreza, 2004 to 2014 WRX (including STI), 2003 to 2014 Legacy and Outback, and 2006 Saab 9 2X vehicle models.

A previous recall replaced the airbag inflators in these vehicles, but the same design of inflators was installed at the time the recall was initially issued.

To repair the issue, Subaru said dealers will replace the airbag inflators free of charge. The company said vehicle owners will be notified beginning in January.

Questions about the recall can be directed to Subaru customer service at 1-844-373-6614. Saab owners can contact the Saab Customer Assistance Center at 1-800-955-9007.

Shares of Subaru stock wre up 0.10% as of 2:51 p.m. EST on Thursday.
