On certain vehicles, the cylinder head may not have been manufactured properly. As a result, the cylinder head plug(s) could fail. If this happens, engine oil could leak and cause a loss of power to the wheels.
Safety Risk
A loss of power to the wheels could increase the risk of a crash. Oil that leaks onto hot components can create the risk of a fire. Additionally, an oil leak could create a hazard for others and increase the risk of a crash.
Corrective Action
Ford will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, replace the cylinder head.
