The official notice
Defect
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. Note: This recall only affects certain vehicles equipped with a 1.5 L engine. This recall could also affect certain cylinder heads sold at dealerships as a replacement part.
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.
Remedy
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.
