TECHNICAL SERVICE BULLETIN: SERVICE ACTION: RECONFIGURE TERMINAL LOCATION OF INTEGRATED MEMORY SEAT (IMS) CONNECTOR (SA467) - This bulletin provides the procedure to reconfigure the terminals location of the Integrated Memory Seat (IMS) connector on some 2022MY Carnival (KA4) vehicles produced from January 4, 2021 through February 26, 2021. The IMS seat position memory buttons 1 and 2 may intermittently not operate the power drivers seat when the rear window defroster switch is on.

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.
