Service bulletin SSM 49784
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 2020-2021 Corsair/Aviator/Navigator and 2021 Nautilus/Mach-E customers may be unable to activate Phone-as-a-key, have intermittent Phone-as-a-key connectivity, missing Phone-as-a-key button in the App, receiving Pairing Failed, Key Download Error or Connection Trouble message during Phone-as-a-key setup, Bluetooth Disconnected, Unable To Start, Backup Code Needed And/or Key Not Detected. Prior to performing any RFA diagnostics, verify the customer's phone app is at the latest version, the phone app is authorized to the vehicle and Location Service is enabled in customer's phone to allow for proper Phone-as-a-key operation. If a Phone-as-a-key concern remains, continue with normal RFA diagnosis. Refer to Workshop Manual (WSM), Section 419-01. Utilize the FordPass Guides or Lincoln Way Concierge teams as needed to understand Phone-as-a-key operation.

| TSB 26-2325 | 2026-10-05. Service bulletin. Some of the vehicles listed in the Model statement above may exhibit a front courtesy lamp that is inoperative. This may be due to a concern with the front courtesy lamp light module. |

| SSM 55194 | 2026-09-30. Service bulletin. 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. |
| TSB 26-2395 | 2026-09-01. Service bulletin. This article supersedes 26-2287. Reason for update: update the labor operation numbers to add MT to operations C, F, G, H, J, K, L and M, and correct the part number LIMZ-4A015-B to L1MZ-4A015-B. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: Harsh engagement Delayed engagement Harsh shift Delayed shift Illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC)s P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module (PCM) or transmission control module (TCM). This may be due to axial movement of the CDF clutch cylinder sleeve causing hydraulic circuit leaks. NOTE: If internal transmission service is required to address a concern detected with the CDF clutch cylinder following this article, technicians should carefully inspect and replace other transmission components and flush transmission fluid cooler only as ne |

| SSM 55080 | 2026-08-20. Service bulletin. 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. |
| SSM55059 | 2026-08-03. Service bulletin. Some 2021-2023 F-150 vehicles equipped with a 3.5L PowerBoost engine, 2020-2026 Explorer vehicles equipped with a 3.3L hybrid engine, and 2020-2023 Lincoln Aviator vehicles equipped with a 3.0L EcoBoost hybrid engine may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P0A1E stored in the powertrain control module (PCM). The vehicle may be unable to enter electric-only drive modes as expected during normal drive cycles. This may be due to the belt integrated starter generator (BISG). For vehicles with this condition, follow the necessary Pinpoint Test in Workshop Manual (WSM), Section 303-06 for DTC P0A1E and repair the vehicle as directed. Note that previous replacement of the BISG does not negate the need for subsequent BISG replacements if directed to do so by the appropriate Pinpoint Test diagnostics. Engineering is investigating this BISG quality concern. Monitor PTS for updates regarding this investigation. |

| SSM 55031 | 2026-07-28. Service bulletin. 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 55028 | 2026-07-28. Service bulletin. 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. |
