Ford will be asking drivers of certain 2012 Ford Edge vehicles equipped with 2.0L engines to bring in their vehicle for problems with the fuel system. The fuel line pulse damper housing could crack due to an improper manufacturing process. The driver may notice a fuel odor or a continuous leak while the system is under pressure, and if unrepaired could result in an engine fire. Ford will be notifying almost 5,500 Edge owners of the problem and will be asking them to bring in their vehicles to have the defective part replaced. For more information, owners are asked to contact the Ford Motor Company Customer Relationship Center at 1-866-436-7332.
