The recall covers trucks from the 2004 through 2006 model years. According to the National Highway Traffic Safety Administration, an electrical short can cause the air bags to deploy unexpectedly, in some cases injuring drivers.
In February, Ford agreed to fix 150,000 of the trucks but resisted the government's wishes to recall all 1.2 million trucks that may have the problem.
Ford said it knows of no crashes caused by the airbag problem, but NHTSA said in a January letter to Ford that the agency knew ofb269 cases in which the air bags deployed inadvertently, resulting in 98 injuries, some serious.
Ford's F-Series pickup truck is the top-selling vehicle in America, and the F-150 makes up about 60 percent of F-Series sales.
