FRANKFURT: Volkswagen AG may have to set aside up to 400 million euros in provisions to cover a recall of vehicles in the United States equipped with Takata air bags, German weekly Welt am Sonntag reported, citing an insider. Germany's three largest automakers said earlier this month they would recall 2.5 million vehicles in the United States equipped with the air bags, the latest in a long-running safety crisis involving the Japanese automotive supplier.
