Official summary
This article supersedes TSB 23-2174 to update the Service Procedure, Part List and adding an additional labor operation. Some vehicles listed in the model statement above may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTCs) C00A6 and/or C0631. This may be due to the front axle disconnect actuator/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.
