Bulletins, newest first
SSM 478142019-04-01. Service bulletin. SEATS. Some 2016-2019 Explorer, 2016-2018 MKX, 2019 Edge/Nautilus, 2017-2019 Fusion/MKZ, and 2018-2019 F-150/Mustang/Expedition/Navigator vehicles equipped with climate controlled seats may exhibit a buzzing noise from the front seats, front seats too warm, and/or inoperative climate controlled front seats. DTCs B14BA:13, B1154:4B, and/or B14B9:13 may also be present. This may be due to loose terminal pin fit on the driver seat module (DSM) connector C341D (16 pin). If a loose terminal pin fit condition is found during normal diagnostics per Workshop Manual (WSM), Section 501-10, a new service pigtail connector (part number 3U2Z-14S411-BRAB) is available. Refer to Wiring Diagram, Cell 119 to make sure C341D is a 16 pin connector and not a 20 pin connector. Refer to Wiring Diagram, Cell 5 for the recommended splicing procedures.
SSM 478122019-04-01. Service bulletin. POWER TRAIN. Some 2017-2019 F-150, 2018-2019 Expedition/Navigator/Mustang, 2019 Ranger vehicles equipped with a 10R80 transmission may exhibit a whine noise. This may occur at idle and while driving coming from the bell housing and front pan area of the transmission. The whine noise may become louder when at operating temperature and increases with higher engine RPM in the PARK position. A small amount of whine noise is considered to be characteristic of the 10R80 transmission due to the offset gear drivetrain in the front support and has no effect on durability.
19B012019-03-04. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Certain 2019 Model Year Expedition and Navigator Vehicles Equipped With R-1234yf Refrigerant - Special Air Conditioning - Evacuation and Charging Service Information
