Service bulletin TSB 20-2352

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2017-2020 Ford GT vehicles built on or before 10-Sep-2020 may exhibit a rattle/buzzing noise from the left rear of the vehicle during hot idle. This may be due to the transmission control module (TCM) calibration. To correct the condition, follow the Service Procedure steps to reprogram the TCM.
