Official summary
Some 2021-2023 Mustang Mach-E vehicles built on or before 24-Jun-2023 may exhibit a condition where the high voltage battery slow charging or does not charge while using a level 1 or level 2 electric vehicle supply equipment (EVSE) after an over the air (OTA) update. This may be due to the software in the secondary on-board diagnostic control module A (SOBDM)
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.
