Official summary
Some 2021 Mustang Mach-E vehicles may exhibit phone as a key concerns of Bluetooth disconnected, unable to start, backup code needed and/or key not detected. This may be due to the software configuration in the remote function actuator module (RFA). To correct the condition, reprogram the RFA module using the latest software level of the appropriate Ford diagnostic scan tool. For claiming, use causal part 14G617 and M-time.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
