Volvo cars, a unit of Ford Motor Co., said on Thursday it is recalling 116,000 S80 cars worldwide, including 49,000 in the United States, over a possible steering problem. The Swedish automaker said 1999 and 2000 models of the full-sized S80 are being recalled because a front ball joint in the front suspension can loosen prematurely, affecting steering, Volvo spokesman Dan Johnston said. Ford and Japan's Mazda Motors Corp. also recalled small numbers of their new small SUVs, built off the same underpinnings or platform.
