Official summary
2021-2023 Mach-E vehicles may exhibit the drive mode default to normal mode while driving and <Drive Mode Not Available> message displays in the center display screen with or without Diagnostic Trouble Code (DTC) U0253 stored in the ABS module. This may be due to the software in the APIM.
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.
