Announced Jan 30, 2013. The recall affects some 2003 and 2004 model year Corollas. A component in the airbag control module can fail, potentially leading to airbag deployment.
Letters are to be mailed to owners. But, these are old cars and addresses may have changed. (I've moved three times since I bought the car). If I don't hear anything after a month or so, I'll call Toyota.
