Subaru of America is recalling a small number of its 2012 Subaru Legacy sedans and 2012 Subaru Outback wagons. According to the National Highway Traffic Safety Administration, the cars have side air bags that might not deploy during a collision and increase the risk of injury to drivers and passengers.

NHTSA says about 381 Subaru Outback and Legacy vehicles were manufactured last December with side air bag components that contain the incorrect propellant mixtures. The improper mixture in the side curtain air bag initiators may prevent the safety devices from deploying during a collision.

Subaru plans on notifying owners of its 2012 Legacy and Outback vehicles in early April. They will be instructed to bring in their vehicles to a local Subaru dealership where mechanics will replace one or both side curtain air bag initiators, free of charge.

For more information, consumers can call Subaru's toll-free customer support line (800-782-2783) and reference Subaru recall number WVZ-36 or visit NHTSA's safety website: www.SaferCar.gov.

Earlier this month, NHTSA also announced recalls of small numbers of 2012 Honda and Toyota vehicles for air bag issues as well.

Honda recalled Honda Civic sedans and Honda Crosstour vehicles while Toyota recalled some RAV4 SUVs and Toyota Camry sedans for similar issues with side air bag initiators.

And last month, NHTSA also recalled 2006-2008 Kia Optima sedans and 2007-2008 Kia Rondo wagons for front air bags that might not deploy due to possible failure of other components.
