Official summary
Some Mustang Mach-E GT vehicles may exhibit a Suspension Fault Speed Limited To 120 km/h (80 mph) message, or Driver Selectable Suspension Fault Service Required message, in the IPC with diagnostic trouble code (DTC) C1121:64. This may be due to the vehicle dynamics module (VDM) software. To correct the condition, follow the service procedure to reprogram the VDM.

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.
