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.

SSM 50693	2022-04-20. Service bulletin. Some 2017-2021 Ford GT vehicles built on or before 22-Sep-2021 may need to have a new battery installed for service. A new design service battery has been released and requires a different battery tray and a different local interconnect network (LIN) connector. This is due to the new battery being smaller and will not properly secure in the original battery tray. The LIN connector socket in the new battery is keyed differently and the original LIN connector will not plug in. The LIN connector will need to be de-pinned, so the new connector shell can be installed. When installing new battery part number: MG7Z-10655-A(USA/MEX), MG7Z-10655-B(CAN), MG7Z-10655-C(GCC) MG7Z-10655-D(EU), the following battery tray and LIN connector must be used: battery tray MG7Z-10732-A, LIN connector shell MG7Z-9A624-A.

This may be due to reduced lubrication and/or dirt present at the front door strut ball and socket joints. If the noise is confirmed to be from the front door strut(s), the front door strut(s) should be removed per Workshop Manual(WSM), Section 501-03. After removal, the front door strut ball on the body and the socket of the front door strut should be thoroughly cleaned of existing grease and dirt.

Some 2019-2021 Ford GT vehicles may exhibit a discharged battery with the battery charger and maintainer connected to the rear hatch storage compartment power point. This may be due to the cigar plug comfort connect end of the battery charger and maintainer not being completely inserted into the rear hatch storage compartment power point or by becoming disconnected when the cable is pulled when the rear hatch is lowered. Before diagnosing, interview the customer about their hook up method and the possibility of the cigar plug comfort connect end not being completely inserted and/or tension on the charge cable when the rear hatch is lowered. A properly connected and powered battery charger and maintainer will have an illuminated green power indicator and a battery charge level indicator showing at all times.
