The recall covers 17,000 Scion xA vehicles in the U.S. from 2004 through 2006.
Also affected in Japan, Europe and elsewhere are the Isis, Avensis, Avensis Wagon, Allex, ist, Wish, Corolla, Corolla Spacio, Corollo Verso, Corolla Fielder, Corolla Runx, and Sienta.
All were built from July 2002 to June 2015.
