Mazda recalls nearly 80K vehicles to replace faulty air bags

Mazda is recalling nearly 80,000 cars and SUVs, some for a second time, to replace dangerous Takata air bag inflators.
The recall covers front passenger inflators on certain 2007 through 2009 and 2012 CX-7, CX-9 and Mazda 6 vehicles. The recalls vary by state and age of the vehicles.
Takata inflators can explode with too much force and hurl shrapnel into drivers and passengers. As many as 19 people have been killed and more than 180 hurt due to the problem.
The recall supersedes one issued in January that temporarily replaced older Takata inflators with the same parts. Ammonium nitrate used in the inflators can deteriorate over time.

The company says newer inflators are safer. In the latest recall, dealers will install permanent replacement inflators that don't use ammonium nitrate.
