Service bulletins for the 2021 Ford Mustang Mach-E

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 510952022-09-26. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Some 2021-2022 Mustang Mach-E, 2022 F-150 Lightning/e-Transit may experience diagnostic trouble codes (DTCs) P1A10 in the secondary on-board diagnostic module C (SOBDMC) and U3012 in the battery energy control module (BECM) after a low voltage service disconnect (LVSD). If both DTCs have set simultaneously, this may be due to the LVSD not being fully seated. Inspect the LVSD C1001 for being fully seated which is located on the left side of the under hood compartment. Refer to Workshop Manual (WSM), Section 414-03A High Voltage Battery > Mounting and Cables > General Procedures.
SSM 504162022-02-04. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; EQUIPMENT; ELECTRICAL SYSTEM:SOFTWARE. Some 2021 Mustang Mach-E vehicles built on or before 20-Oct-2021 may exhibit illuminated instrument panel cluster (IPC) backlight with key-off, causing 12V battery drain. To resolve this condition, park the vehicle and close doors, allow vehicle to enter key-off status, wait for the brake indicator to turn off, turn on hazard lights for 3 flashes and turn off. An IPC software update is expected to be delivered to vehicles via an over-the-air (OTA) update in March 2022 to permanently resolve the condition. Let the customer know they can continue to drive the vehicle and advise to connect to their FordPass account to enable OTA delivery. Schedule a follow-up appointment for April 2022, and contact the customer to verify the OTA was received and confirm if the service appointment is going forward. Monitor OASIS for updates.
