Honda (American Honda Motor Co.) is recalling certain 2003 Honda Accord Coupe vehicles, equipped with a four-cylinder engine. If the passenger frontal air bag module has been replaced, such as after a crash necessitating frontal air bag deployment, the replacement air bag module may include a Takata air bag inflator. These inflators may rupture due to propellant degradation occurring after long-term exposure to lower absolute humidity, temperature and temperature cycling.
