Volkswagen is recalling certain 2012 Audi A6 sedans manufactured between April and May 2011. Because of a problem with the stitching process of the curtain air bag, the air bag may not deploy properly leaving occupants unprotected. Volkswagen will notify owners, starting January, and will replace both the left and right curtain air bags. Owners wanting more information about the recall can contact Volkswagen at 1-800-822-8987.
