Service bulletin SSM 50163

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 Navigator and Aviator vehicles may exhibit a condition where the degrees do not appear in the SYNC screen when adjusting the climate control temperature. This may be due to the SYNC software installed in the accessory protocol interface module (APIM). Engineering is currently developing a software update that is expected in January 2022. Once the software update is available, it will be made available to customers who have enabled SYNC 3 Automatic Updates with their vehicle connected to a Wi-Fi network. Repair appointments should be scheduled for customers in February 2022 who do not receive Automatic Updates. Monitor OASIS for updates.

Other bulletins for the same vehicles and component
TSB 26-23252026-10-05. 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.
TSB 26-23952026-09-01. 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
SSM550592026-08-03. 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 550282026-07-28. 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.
SSM 550372026-07-27. Service bulletin. Some 2018-2024 Expedition and 2018-2027 Navigator vehicles equipped with a rear seat entertainment system/Lincoln Play may experience various system concerns. Rear seat entertainment systems are not on a controller area network (CAN) and are not supported by the Ford Diagnostic and Repair System (FDRS). Certain system concerns may be resolved through software updates which will automatically download once each individual monitor is connected to Wi-Fi. Diagnostic support for rear seat entertainment systems is provided by VOXX electronics. If necessary, contact the VOXX Customer Service Department at 1-866-869-7888. If possible, record the device serial number by selecting the gear/Setup icon > Settings > Device and Software > About. If the unit will not power up, the serial number is on a label on the back of the monitor. It is helpful to know the date the issue occurred, how long the monitors were on prior to the issue, what app/input/media was being used, and if the system software was recently updated prior to the concern starting. For claiming, refer to the Warranty and Policy manual for

SSM 547202026-04-10. Service bulletin. 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.
SSM 547022026-04-06. Service bulletin. Some 2020-2023 Aviator and 2020-2024 Explorer/Police Interceptor Utility hybrid vehicles may exhibit a "Refuel Error See Manual" message in the instrument panel cluster (IPC) after installing a replacement fuel filler door assembly (7827936). This may be due to a concern with the replacement fuel filler door assembly. This condition does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time.
SSM 545892026-03-04. Other. Some 2019-2024 Ford and Lincoln vehicles equipped with SYNC3 may experience various connectivity concerns with The Ford App Lincoln App including but not limited to: missing activation prompt pop-upon the vehicle's center display screen when attempting to activate vehicle through The Ford App Lincoln App, incorrect location global positioning system GPS reported through The Ford App Lincoln App, problems with remote commands being performed through The Ford App Lincoln App and or incorrect data information reported on The Ford App Lincoln App. These symptoms will be accompanied by diagnostic trouble code DTC B156D 89 in the TCU. This may be due to the accessory protocol interface module APIM software. To correct the condition, update the APIM software.
