Official summary
Some 2021-2022 Mustang Mach-E vehicles equipped with all-wheel drive (AWD) may exhibit a whine noise from the front drive unit when driving steady speed between 30-40 mph (48-64 km/h) without diagnostic trouble codes (DTCs) present. This may be due to software parameters. To correct the condition, follow the Service Procedure to reprogram the powertrain control module (PCM)
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.
