# Service bulletin SSM 49643

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 2021 F\-150, Mustang Mach\-E, Edge vehicles may exhibit a concern of Android Auto not wirelessly connecting and/or Android phones rebooting when connected to the vehicle via USB. This is due to a concern with the Google application on the customers device. Google has released a fix for these concerns. For Android phones not connecting wirelessly, request that the customer update their Android Auto version to 6.1 or later. For customers whos Android phone reboots when connected via USB, request that the customer update their Chrome application to 88.0.4324.181 or later. The customers service provider should be able to assist customers having difficulty updating their device. This is not a warrantable repair

- [SSM 55194](/bulletins/11037561.md), 2026-09-30, 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.

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](/bulletins/11036286.md), 2026-08-20, 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.

- [SSM55059](/bulletins/11035556.md), 2026-08-03, Service bulletin: POWER TRAIN; ELECTRICAL SYSTEM; UNKNOWN OR OTHER; FUEL/PROPULSION SYSTEM. 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.
