Quick answer

Some 2021-2022 Mustang Mach-E built on or before 17-Sep-2022, 2022 e-Transit vehicles may exhibit an illuminated red triangle indicator lamp with diagnostic trouble code (DTC) P27B4 stored in the secondary on-board diagnostic control module C (SOBDMC) or the charge status indicator (CSI) is blinking red with DTC P0A7F stored in the battery energy control module (BECM) and/or P0CF7 stored in the secondary on-board diagnostic control module A (SOBDM). This may be due to an unsecured plug-in electric vehicle supply equipment (EVSE). To correct the condition, follow the Service Procedure to reprogram the SOBDM.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
