The vehicles affected this time around include the 2003-2008 Mazda 6 sedans, hatchbacks, and wagons, 2006 to 2007 Mazdaspeed 6 sedans, and the 2004 MPV minivan, as well as 2005-2006 MPV models in states with warmer and more humid climates that could affect the airbags. Mazda had previously recalled these vehicles, but at first could only replace faulty airbags with an updated version of the same design. Now, the company says it will swap in completely redesigned versions.
