Service bulletin SSM 50320
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 2017-2021 Ford GT vehicles built on or before 22-Sep-2021 may need to have a new battery installed for service or maintenance purposes. A new battery design has been released for service and requires a different battery tray and a different local interconnect network (LIN) connector. This is due to the new battery design being dimensionally 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 connector shell will not plug in. The LIN connector shell will need to be de-pinned, so the new connector shell can be installed. When installing new battery part number MG7Z-10655-*, the following battery tray and LIN connector must be used: battery tray MG7Z-10732-A, LIN connector shell MG7Z-9A624-A. Refer to Workshop Manual, Section 414-01 for battery tray replacement.

| SSM 50975 | 2022-08-02. Service bulletin. Some 2017-2022 Ford/Lincoln customers may experience a notification in the FordPass®/LincolnWay® app indicating Vehicle Has Entered Deep Sleep Mode. This occurs when the vehicle has not been started for 14 consecutive days, battery voltage is at/below 9.5 volts or the body control module (BCM) 12 volt battery state of charge (SOC) drops below 50%. A warning may also set if the telematic control unit (TCU) has received an over the air update. The TCU powers down all communication when in this mode and app features are disabled. Manually start the vehicle to wake if from mode. More information is located in the app under: Account > Help > search 'Deep Sleep' in the entry box. If the condition remains, check the BCM 12v SOC. If the SOC does not change after charging the battery or after BMS reset is performed, continue with normal battery and/or BMS sensor diagnostics. |

| 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. Refer to Workshop Manual, Section 414-01 for battery tray replacement. |
| SSM 49888 | 2021-07-02. Service bulletin. Some 2017-2021 Ford GT vehicles may exhibit diagnostic trouble code (DTC) P166B present in the gear shift module (GSM) after an on-demand self test is performed. This is likely due to the driver door not being fully closed and locked during the on-demand self-test. A false P166B DTC can set if the driver door is not fully closed or if it is unlocked during the self-test. If P166B is still present with the driver door fully closed and locked during the on-demand self-test, continue with normal diagnostics in Workshop Manual (WSM), Section 307-05. |
| TSB 20-2352 | 2020-11-05. Service bulletin. 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. |
