Official summary
Some 2024 Mustang vehicles may exhibit an illuminated MIL with DTC P059F stored in the powertrain control module (PCM). This may be due to a loose and/or detached vane on the active grille shutter from the factory. To correct this concern, replace the active grille shutter. Refer to Workshop Manual (WSM) Section 501-02 Front End Body Panels > Removal and Installation > Active Grille Shutter. For claiming, use causal part 8475 and applicable labor times in Section 12 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.
