The problem: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2016 4Runner, 2003-2006 Tundra, 2003-2013 Corolla, 2009-2010 Corolla Matrix, 2004-2005 RAV4, 2002-2007 Sequoia, 2011-2013 Sienna, 2008-2012 Scion xB, 2008-2009 Lexus IS-F, 2007-2012 Yaris and Lexus ES350, 2010-2017 Lexus GX460, 2002-2010 Lexus SC430, 2006-2012 Lexus IS250 and IS350 and 2010-2015 Lexus IS250C and IS350C vehicles. These vehicles had their driver or passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.
The risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
The fix: Toyota will notify owners. Depending on the vehicle model, dealers will replace the front driver inflator, front passenger airbag inflator, the airbag assembly, or the front passenger airbag sub-assembly and inflator.
