Vehicle description: Bi-fuel vehicles modified to run on either gasoline or compressed natural gas (CNG). The natural gas fuel tanks have a solenoid shut-off valve that stops fuel flow from the fuel tank in the event of certain moderate to severe collisions. If the vehicle is in a collision and the natural gas fuel line is damaged, the system could leak natural gas.
Ford has requested owners of these vehicles to have the CNG fuel system disabled under a previous recall campaign and to only use gasoline fuel until a permanent corrective action is developed. Owners are being alerted to this solenoid valve concern at this time. The timing of corrective actions is being delayed to allow both conditions to be remedied at one time. In the meantime, there is not risk as long as the natural gas system has been disabled and the vheicle is only operated on gasoline.
