Summary

This article supersedes TSB 23-2168 to update the vehicle line affected. Some 2021-2022 Mustang Mach-E (non-GT) vehicles equipped with all-wheel drive (AWD) may exhibit a whine noise from the front drive unit when driving steady at speeds 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).

Owners of these vehicles have filed 249 complaints in the electrical category.
