Official summary
Some 2020-2023 Mustang (non-GT500/GT350) vehicles equipped with vehicle dynamic suspension may exhibit a Dynamic Suspension Fault message displayed in the IPC with diagnostic trouble code (DTC) B14C1:64 with no vehicle symptoms. This may be due to software within the vehicle dynamics module (VDM). To correct the condition, reprogram the VDM using the latest software level of the appropriate Ford diagnostic scan tool.
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.
