The official notice
Defect
On certain Fusion Energi plug-in hybrid electric vehicles (PHEV), the high-voltage battery energy control module could become damaged. If this happens, there could be a loss of power to the wheels or the control module could overheat.
Safety Risk
A sudden loss of power to the wheels could increase the risk of a crash. A battery energy control module that overheats can create the risk of a fire, even while the vehicle is parked and turned off.
Remedy
Ford will notify owners by mail. As an interim repair, Ford will advise you to take your vehicle to a dealership to install a fuse block for the battery energy control module. The dealer will also update the BECM software. When the final repairs are available, Ford will notify owners by mail and advise you to take your vehicle to a dealership to replace the high-voltage battery. To mitigate the safety risk, Ford advises you not to charge your vehicle until the recall repairs are completed.
