Some 2013-2023 Ford or Lincoln vehicles with modems activated through FordPass or LincolnWay may experience 12 volt battery drain symptoms when the customer uses non-Ford/Lincoln phone applications as an alternate channel to access vehicle commands such as door lock/unlock, remote start, vehicle location, etc. The battery drain may be caused by excessive calls for data through the vehicle network keeping it in an activated state. Recommend that the customer uninstall the app to ensure this is not contributing to battery symptoms experienced. Advise the customer that unaffiliated third-party app developers do not work directly with Ford to adhere to security, vehicle communication, and privacy requirements.
