SSM 501312021-09-28. Service bulletin. POWER TRAIN; ENGINE; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Some 2021 Bronco Sport vehicles may exhibit a hiss or rattle noise in the engine compartment while driving which may be originating from the manual park release cable. Disconnect the cable from the transmission and road-test to confirm the noise is eliminated. If the noise is still present, refer to Workshop Manual (WSM), Section 100-04 for diagnostic and repair information. If the cable is causing the noise, reconnect the cable and inform the customer that Ford is working on a solution which is expected to be available by mid-December 2021. Advise the customer that the vehicle is safe to drive and schedule a follow-up appointment for mid-December. Once the solution becomes available, contact the customer and confirm the service appointment is going forward. Monitor OASIS for updates.
SSM 500152021-09-04. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; VISIBILITY; EQUIPMENT. Some 2020-2021 Ford and Lincoln vehicles are equipped with an anti-fogging feature known as enhanced windshield anti fogging strategy (EWAFS). This feature automatically adjusts airflow in the cabin to prevent the windshield from fogging up and may be perceived by customers as irregular climate control functionality. To reduce fogging, the EWAFS functions include: the air condition (A/C) button may turn on and off automatically, recirculated air may turn off automatically in all air modes except MAX A/C, recirculated air may also turn on and off automatically in various airflow modes in order to improve heating or cooling efficiency, and in auto climate control, high humidity conditions may automatically engage A/C compressor, increase blower motor speed and/or direct more air to windshield. Continue to monitor the Workshop Manual (WSM) for EWAFS updates.
