SummarySome 2021-2025 Ford/ Lincoln vehicles equipped with SYNC4 may not be able to perform an update to the accessory protocol interface module (APIM). This may be due to the software in the APIM. Ford Engineering has de-activated the ability to update these SYNC4 APIM modules as applicable, and the Ford Diagnosis and Repair System (FDRS) will not present an update for the APIM module. Some existing directed repairs may be impacted, check Professional Technician System (PTS) before attempting any specific technical service bulletin (TSB)/special service message (SSM) and check field service action (FSA) landing pages before attempting any FSA repairs. For any vehicle repairs requiring a software update that includes an APIM update in the programming sequence, if the 5-digit product code for the APIM software is equal to or lower than 23187, do not attempt to update affected modules at this time. To determine the 5-digit product code for the APIM software on the vehicle, while the vehicle center display screen is powered up with ignition in run or accessory, go to Settings > General > About SYNC.

SummarySome 2021-2025 Bronco vehicles may exhibit a water leak from the A-pillar, overhead console/upfitter switches and/or sun visors. If a leak is identified from this area, refer to Workshop Manual (WSM), Section 501-18 Pinpoint Test (PPT) G for water leak diagnosis. If the PPT leads to the replacement of the header seal, a revised header seal has been released for service (M2DZ-7803110-H) which contains a thicker consistent bead of butyl across the entire length of the seal. The header seal will need to be firmly depressed and massaged to make sure all of the butyl that is across the entire header seal will properly adhere to the body, creating a water-tight seal. For claiming, use causal part 7803110 and labor operation 03110A in Section 12 of the Service Labor Time Standards (SLTS) Manual.

SummarySome 2021-2024 Bronco vehicles built on or before 01-Jan-2025 equipped with a 2.3L EcoBoost engine and 10R60 automatic transmission may exhibit diagnostic trouble codes (DTCs) P0300, P0301, P0302, P0303, and P0304 and may be accompanied by a buck/jerk sensation while driving between 35-55 mph (56-89 km/h) in gears 7-10. If the condition remains after normal engine misfire diagnostics and associated repairs have been performed, the condition may be related to driveline torsional vibration induced by the rear wheels and/or rear axle assembly. The driveline torsional harmonics/vibrations are incorrectly identified by the misfire monitor as an engine misfire. Perform standard road force wheel balancing of all four tire and wheel assemblies and retest. If the condition continues to occur, replace the ring and pinion gearset in the rear axle. For claiming, use causal part 4209 and applicable labor operations found in Section 04 of the Service Labor Time Standards (SLTS) Manual.

SummaryDrivers of some 2020-2025 Escape, 2021-2025 Bronco Sport and 2022-2025 Maverick vehicles may report the uncommanded locking of the driver door after the door is closed. This may be due to the driver placing their hand on the interior front door handle and inadvertently pushing the manual door lock toggle into the lock position. If the lock and latching mechanisms are functioning normally, and if there are no related diagnostic trouble codes (DTCs) or other issues identified, then the system is operating as designed.
