The National Highway Traffic Safety Administration is upgrading its investigation into thousands of Mini Coopers that may experience power-steering loss. The agency is also investigating Ford's popular pickup truck, the F150.
The agency is looking into a fuel tank problem that may affect more than two million Ford F150 pickups.
Steel straps holding the gas tanks can rust, break and cause a fuel spill or a fire.
There have been more than 200 reports of the tanks breaking causing two fires. The investigation includes F150 pickup trucks from the 1997 through 2001 models years.
Ford's F150 is the top-selling vehicle in the country.
