Official summary
Some 2020 Corsair/Aviator vehicles may exhibit inoperative heated/cooled seat and/or steering wheel functionality when starting the vehicle using remote start. The heated/cooled seats and/or heated steering wheel may not turn on when previously set to on/auto. This may be due to software in the heating, ventilation, and air conditioning (HVAC) control module. To correct this condition, reprogram the HVAC control module to the latest software level of the appropriate Ford diagnostic scan tool. For claiming, use causal part 18C612 and applicable labor operations in Section 10 of the Service Labo

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
