Service bulletin SSM 49983

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 vehicles may experience the IPC going blank or rebooting during an incoming or outgoing cell phone call. This may be due to the cell phone connected to SYNC having an emoji alongside the text of a name in the cell phone's contact list. If suspected, interview the customer about the concern happening during calls only with specific contacts. If confirmed, have the customer remove any emojis alongside the text of names in their contact list and re-evaluate. Inform customers that Ford is developing a software update that is expected in October. Let the customer know they can continue to drive the vehicle and schedule a follow-up appointment for repair in November. Once the update becomes available, contact the customer and confirm the service appointment is going forward. Monitor OASIS for updates.

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 550312026-07-28. 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 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.
