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.

26B072026-10-02. Other. FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL; UNKNOWN OR OTHER; ELECTRICAL SYSTEM. Recommended Repair Prior to Sale Customer Satisfaction Program 26B07 Certain 2021-2025 Model Year F-150 Lightning and Mustang Mach-E Vehicles Undesired Acceleration Due to Adaptive Cruise Control (ACC) Activation
SSM 551942026-09-30. Service bulletin. ELECTRICAL SYSTEM; EXTERIOR LIGHTING; UNKNOWN OR OTHER. Some 2021-2024 Mustang Mach-E, 2025-2026 Navigator and 2024 F-150 vehicles may exhibit inoperative welcome/approach detection lights. This may be due to the body control module (BCM) software. To correct the condition, download and run the "BCM - Programmable Module Installation (PMI)" application using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. If the condition persists after PMI, refer to Workshop Manual (WSM), Section 417-01 for normal diagnostics and repair as necessary outside of this article. For claiming, use causal part 15604 and labor operations 12651D and BCM.
SSM 550802026-08-20. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER; FUEL/PROPULSION SYSTEM. Some 2021-2023 Mustang Mach-E vehicles built on or before 25-Jun-2023, 2022-2025 E-Transit and 2022-2023 F-150 Lightning vehicles may experience a high voltage battery stop charging condition when using a direct current (DC) fast charger level 3 with diagnostic trouble codes (DTCs) P0EEE:27 and P2E53:27 stored in the on-board diagnostic control module A (SOBDM). This may be due to the SOBDM software. Replacement of the charge port will not resolve this concern. Inform customers that their vehicles can still be charged using a level 1 or level 2 alternating current (AC) charger. Engineering is currently working on a software solution expected in Q3 2026. Schedule an appointment with the customer when the repair becomes available. Monitor Professional Technician System (PTS) for additional information.
SSM 550312026-07-28. Service bulletin. UNKNOWN OR OTHER; FUEL/PROPULSION SYSTEM; ELECTRICAL SYSTEM. Some 2021-2026 Ford/Lincoln vehicles may exhibit various symptoms including but not limited to the auto start/stop system not operating as intended with a "Check Charging System" message in the instrument panel cluster (IPC) while the charging system is operating properly with no charging related diagnostic trouble codes (DTC) stored. This may be due to someone using an aftermarket programmer to change the body control module (BCM) configuration to disable the auto start/stop system or perform other unsupported programming modifications. To correct this condition on F-150 and Bronco vehicles, download and run the Ford Diagnosis and Repair System (FDRS) application titled "BCM-Charging System Configuration Correction". Running this application will determine if the BCM configuration was modified by the customer and if so, provide the option to return the configuration back to factory settings. For other vehicle models exhibiting concerns related to unsupported aftermarket BCM programming, submit a Technical Support Request (TSR) requesting support to revert the BCM configuration
SSM 550282026-07-28. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER. Some 2021-2024 Ford and Lincoln vehicles may exhibit an "Updating SYNC" message on the vehicle center display screen after an over the air (OTA) update. The message can be cleared from the center display screen and SYNC can be used normally, but it will re-appear at every subsequent ignition cycle. Inform customers that engineering is currently working on a software update solution for this condition to be delivered OTA expected in late Q3 2026. Software will update automatically if vehicle connectivity is enabled in the vehicles settings. Monitor Professional Technician System (PTS) for additional information.
SSM 550082026-07-20. Service bulletin. ELECTRICAL SYSTEM; VISIBILITY/WIPER; SEATS; UNKNOWN OR OTHER. Some 2021-2026 Ford vehicles may exhibit inoperative heated/cooled seats, heated steering wheel and/or front/rear defrost features after a remote start is performed through the Ford mobile application or with the key fob. Customers may also experience heated/cooled seats, heated steering wheel and/or front/rear defrost features turning on in unexpected conditions such as during warmer weather. These features will operate normally when commanded in the center display screen. This may be due to the customer not setting up their "Climate Settings" through the Ford mobile application. To correct this condition, inform the customer they should perform a remote start from the Ford mobile application and then adjust the "Climate Settings" in the Ford mobile application as desired. These settings only need to be set once and will persist through subsequent remote starts. Heated and cooled seats will be set to Level 2 when turned ON via "Climate Settings" in the Ford mobile application during a remote start event. This is normal operating characteristic. This condition does not affect vehicle durability and no a

Some 2021-2024 Mustang Mach-E vehicles may exhibit only continuous memory diagnostic trouble code (DTC) U2016:47 stored in the power steering control module (PSCM) after a self test is performed with the Ford Diagnosis and Repair System (FDRS) scan tool. If the vehicle does not exhibit any observable symptoms such as lack of/reduced power steering assist, disabling of power steering assist features and/or power steering assist fault messages displayed on the instrument panel cluster (IPC), this DTC should be ignored. No further service action is required.

SSM 547202026-04-10. Service bulletin. ELECTRICAL SYSTEM; LANE DEPARTURE: BLIND SPOT DETECTION. Various 2020-2026 Ford and Lincoln vehicles equipped with blind spot information system (BLIS) may experience an inoperative blind spot monitoring with a "Blind Spot System Fault" message displayed in the instrument panel cluster (IPC). This may also be accompanied by diagnostic trouble codes (DTCs) B118C:11 and/or B118C:15 stored in the driver door module (DDM), and/or B118D:11 and/or B118D:15 stored in the passenger door module (PDM). This may be due to the wiring connector from the mirror to the BLIS module. If diagnostics lead to an internal mirror wiring harness fault, a new lower level BLIS light pigtail is now released for service. It is not necessary to replace the exterior mirror assembly. Use part number SC3Z-14A411-B to resolve the concern.

This article supersedes TSB 25-2058 to update: service procedure enhancements, and increase labor operation allowances. Some of the vehicles listed in the Model statement above may exhibit a 12-volt battery drain. This may be due to the software level of various modules such as the gateway module (GWM), accessory protocol interface module (APIM) and driver front seat module (DSM).
SSM 544242025-12-10. Service bulletin. STRUCTURE:BODY. Some 2021-2025 Mustang Mach-E vehicles may exhibit a condition where the front luggage compartment hood is hard to close. This may be due to an alignment issue with the hood. The most common adjustments to improve closing efforts involve the hood front up and down alignment and the bump stop rubbers. Refer to Workshop Manual, Section 501-03 Body Closures > General Procedures > Hood Alignment for procedures on proper adjustments that can improve front luggage compartment hood closing efforts.
