Official summary
Some 2021 Mustang Mach-E (Non-GT) vehicles built on or before 22-Jul-2021 may exhibit a buzz noise from the instrument panel cluster (IPC) that changes with the brightness setting. This may be due to the internal hardware in the IPC. To correct the condition, replace the IPC. Refer to Workshop Manual, Section 413-01. For claiming, use causal part 10849 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
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.
