SSM 550082026-07-20. Service bulletin. ELECTRICAL SYSTEM; VISIBILITY/WIPER; SEATS; UNKNOWN OR OTHER. Some 2021-2026 Ford vehicles may exhibit inoperative heated/cooled seats, heated steering wheel and/or front/rear defrost features after a remote start is performed through the Ford mobile application or with the key fob. Customers may also experience heated/cooled seats, heated steering wheel and/or front/rear defrost features turning on in unexpected conditions such as during warmer weather. These features will operate normally when commanded in the center display screen. This may be due to the customer not setting up their "Climate Settings" through the Ford mobile application. To correct this condition, inform the customer they should perform a remote start from the Ford mobile application and then adjust the "Climate Settings" in the Ford mobile application as desired. These settings only need to be set once and will persist through subsequent remote starts. Heated and cooled seats will be set to Level 2 when turned ON via "Climate Settings" in the Ford mobile application during a remote start event. This is normal operating characteristic. This condition does not affect vehicle durability and no a
SYNC-25.1.7.10.1 MachE2026-02-25. Over-the-air update. VISIBILITY/WIPER; UNKNOWN OR OTHER; ELECTRICAL SYSTEM. 25S49 Recall Remedy: -Infotainment software update to address frozen screens
TSB 24-22302024-07-29. Service bulletin. VISIBILITY/WIPER. This article supersedes TSB 24-2002 to update the symptom, production fix date and the service procedure. Some 2021-2024 Mustang Mach-E vehicles built on or before 09-Jul-2024 may exhibit a wind noise from the exterior mirrors/A-pillar area when driving between 25 mph-40 mph (32 km/h-64 Km/h). This may be due to poor sealing of the lower mirror foam and the glass top run foam. To correct this condition, follow the Service Procedure to install new lower inner foam and the glass top run foam.
TSB 24-20022024-02-06. Service bulletin. VISIBILITY:REARVIEW MIRRORS/DEVICES; EQUIPMENT. Some 2021-2023 Mustang Mach-E vehicles built on or before 04-Dec-2023 may exhibit a wind noise from the exterior mirrors/A-pillar area when driving at or above 40 mph (64 km/h). This may be due to poor sealing of the lower mirror foam and the glass top run foam.
TSB 23-20882023-04-04. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. Some 2021-2023 Mustang Mach-E vehicles may exhibit a lack/loss of heat and/or windshield interior fogging while driving during freezing temperatures. This may be due to the heating ventilation and air conditioning (HVAC) control module software. To correct the condition, follow the Service Procedure to update the HVAC control module software.
22B282023-01-06. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. Ensure your vehicle is providing optimal output from its heating system, we have developed a software update to improve the heating capability, defrost and defog performance when exterior temperatures are at or below -15C/5F.
OTA 22B282022-11-04. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; VISIBILITY. Customer Satisfaction Program 22B28 for 2021-2022 Model Year Mustang Mach-E vehicles is now available. Quality Improvements Include: Improved HVAC system heat capability when exterior temps are at or below -15 C/5 F
TSB 22-21822022-05-12. Service bulletin. VISIBILITY. Some 2021-2022 Mustang Mach-E vehicles may exhibit a lack/loss of heat while driving during freezing temperatures. This may be due to the heating ventilation and air conditioning (HVAC) control module software. To correct the condition, follow the Service Procedure to update the HVAC software.
SSM 506452022-04-13. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM:ENGINE COOLANT HOSES AND FITTINGS. Some 2021-2022 Mustang Mach-E vehicles may exhibit a lack/loss of heat while driving during freezing temperatures. The Workshop Manual, Section 412-00 pinpoint test J has been updated to aid in proper diagnosis. This may be due to the heating ventilation and air conditioning control (HVAC) module software. Recommend the customer to use AUTO Mode and adjust the temperature to maximize heater performance. This does not affect vehicle durability and no additional diagnosis or service is required at this time. Inform customers they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in late April 2022. Replacement or reprogramming of the HVAC will not resolve this condition. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available.
TSB 21-23692021-11-02. Service bulletin. VISIBILITY:WINDSHIELD; EQUIPMENT; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Some 2021 Mustang Mach-E vehicles built on or before 15-Feb-2021 may exhibit a wind noise turbulence noise at the top of the windshield when travelling above 45 mph (72 km/h). This may be due to the underflush condition of the windshield to glass roof at the top header area being greater than maximum spec of 4.4 mm. To correct the condition, follow the Service Procedure to install the weather strip/moulding.
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.
