DETROIT (AP) -- Ford is recalling some of its 2012 Edge vehicles because of concerns that the fuel line could leak and potentially cause a fire.

The recall affects about 5,500 vehicles.

The problem is caused by a part in the fuel line that could crack. If it did, the smell of gas would probably be noticeable, and fuel leaks might also appear. Those conditions could cause a fire under the hood.

The Edge is a midsized SUV, and the affected vehicles have 2-liter engines.

Ford blamed faulty manufacturing by a parts supplier.

Ford will notify owners to take their vehicle to a dealer and it will do any necessary repairs for free. Ford says it's aware of 12 cases of fuel leaks. No accidents, injuries or fires have been reported.
