Some 2016-2017 Ford and Lincoln vehicles equipped with SYNC 3 version 2.2 software may exhibit a blank screen after attempting to exit Valet mode. To recover the screen, perform a complete ignition cycle (key off, open and close the driver's door then wait 5 minutes). The SYNC software version of the vehicle can be confirmed via OASIS. Do not attempt any repairs at this time. Engineering is investigating; Monitor OASIS for updates.
