U.S. safety regulators have closed an investigation into steering problems in more than 500,000 Ford full-size cars without seeking a recall.
The largest recall involves 159,395 Focus ST and Escape vehicles from the 2013 and 2014 model years. Ford says their engines could hesitate or stall because of a wiring problem.
Ford is recalling 370,000 cars due to potential corrosion to the steering shafts that may result in loss of steering. About 355,000 cars are in the U.S. and 15,000 are in Canada.
Auto safety regulators in the U.S. are deciding if they will investigate a complaint that the steering can fail on the Toyota Prius.
