Defect
On certain vehicles, the battery monitor sensor could be damaged during servicing. If this happens, the battery monitor system could short circuit.
Safety Risk
A short circuit could create a fire risk, even while the vehicle is parked and turned off.
Remedy
Ford will notify owners by mail and instruct you to bring your vehicle to a Ford dealership to install an in-line fuse for the battery monitor sensor. Ford advises to park your vehicle outdoors and away from other vehicles or structures until the recall repairs have been completed.
