SSM 494772021-02-04. Service bulletin. EQUIPMENT. Some 2015-2021 F-150, 2016-2018 MKX, 2019-2021 Nautilus, 2015-2021 Edge, 2017-2019 Fusion, 2017-2020 MKZ And 2017-2020 Continental vehicles equipped with a 2.7L/3.0L EcoBoost engine may appear to have a low engine oil level if the proper procedures are not followed. Refer to the Owner's Manual > Maintenance > Engine oil check section. When checking the engine oil level after shutting off the engine wait at least 15 minutes prior to checking in order to allow the oil to drain back to the oil pan. The engine oil level can be checked immediately if the engine has not been started. When changing the engine oil the engine needs to be at normal operating temperature and the oil filter removed before draining the oil. Allow the oil pan to drain completely for up to 5 minutes. Check oil level after filling by following the oil level check procedure.
TSB 20-23732020-11-05. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; AIR BAGS. 2015-2018 Edge, 2016-2018 MKX vehicles equipped with active front steering (AFS) may require additional service when replacing the driver airbag using certain part numbers only and/or if replacing the restraints control module (RCM). In addition, some vehicles may exhibit diagnostic trouble code (DTC) U2300 stored in the RCM if the correct programming procedure was not followed.
SSM 492922020-11-04. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2018-2020 Ford and Lincoln vehicles may exhibit inoperative remote features via the Ford Pass/Lincoln Way mobile app, incomplete user authorization, no modem electronic serial number (ESN) displayed or DTCs U2100 and/or B156D in the telematics control unit (TCU). These symptoms may persist even after performing a TCU software update and/or replacement. To correct this condition, start a new session with the latest version of the appropriate diagnostic scan tool and perform a PMI on the TCU. If issues persist, open a hotline assistance request and include the IDS version (if applicable) used to perform the PMI and the Authorization Status PID value in the TCU datalogger. For claiming use causal part 14H092 and applicable labor times in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 492842020-11-04. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; ELECTRICAL SYSTEM:SOFTWARE.

Check the vehicle specifications or vehicle build information for the mfal code. If mfal = WAFAC or WAFAB do not replace the TCU, engineering is currently investigating this condition. Inform customers Ford is developing a software fix that is expected in early January. In the interim, let the customer know they can continue to drive the vehicle and schedule a follow-up appointment with the customer for early January. Once the update becomes available, contact the customer and confirm the service appointment is going forward. Monitor OASIS for updates.
SSM 492172020-10-06. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM:ADAS:BLINDSPOT:SOFTWARE.
