Affected Component: ELECTRICAL SYSTEM

Summary
Some 2019 Mustang/Fusion/Edge/F-150/Continental/MKZ/Nautilus/Ranger vehicles with SYNC 3 may show a pop-up message every key cycle that states Network Connection Needed - To complete the system updates your vehicle should connect to a Wi-Fi network or through the FordPass/LincolnWay app. Until the update is completed, some features may not be available. Would you like to attempt to connect to a Wi-Fi network now? This message may occur, even if SYNC has been connected to a trusted Wi-Fi source. To temporarily remove the inconvenience of this pop-up message, advise the customer from SYNC to select Settings > Automatic Updates > System Wi-Fi and turn off System Wi-Fi, then turn off automatic system updates. Engineering is investigating, monitor OASIS for updates.
