Mazda adds 540,000 vehicles to Takata air bag recall

DETROIT — Mazda is recalling nearly 540,000 cars and pickup trucks in the U.S. and Canada to fix air bags that potentially can explode with too much force.

The automaker says in documents posted by safety regulators that it's recalling nearly 503,000 cars to fix driver's air bags and another 35,000 small pickup trucks to fix passenger air bags.

Affected models with faulty driver's air bags include the 2003-2008 Mazda 6, 2006 to 2007 MazdaSpeed 6 and the 2004 to 2008 RX-8. The company also is recalling 2004 to 2006 B-Series pickup trucks to replace passenger air bag inflators.

The vehicles are equipped with inflators made by Takata Corp. Last month Takata agreed to recall 33.8 million of the devices, making it the largest auto recall in U.S. history.
