DETROIT » Subaru is recalling an undetermined number of vehicles because of air bag problems that have affected much of the global auto industry.

The recall covers the 2003-2005 Baja, Legacy and Outback and the 2004-2005 Impreza, as well as the 2005 Saab 9-2X made by Subaru.

It only affects vehicles in Florida, Puerto Rico, Hawaii and the U.S. Virgin Islands with air bag inflators made by Takata Corp.

The front passenger inflators can rupture, causing metal fragments to fly out when the air bags are deployed. That can injure passengers.

Faulty air bags have been blamed for recalls of millions of cars in recent years.

Subaru says it’s doing the recall as a precaution and to cooperate with a government investigation. Owners will be notified later.
