Official summary
Some 2020 Mustang GT500 vehicles may exhibit a lack of power and/or an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P1288. If this is found to be caused by a damaged supercharger drive assembly, be aware that it is now available to service separately from the supercharger assembly. Refer to the parts catalog and Workshop Manual (WSM), Section 303-12.
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.
