Official summary
Some 2020-2021 Explorer/Aviator vehicles equipped with all-wheel drive (AWD) built on or before 30-Aug-2021 may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTC) C00A6 and/or C0631. This may be due to the front axle disconnect actuator/intermediate shaft. To correct the condition, follow the Service Procedure to replace the front axle disconnect actuator/intermediate shaft with a revised intermediate shaft.
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.
