Some 2022 Aviator vehicles built on 19-Apr-2022 and through 11-Jul-2022 may exhibit the seat lumbar settings not populating in the center display screen. The customer may also indicate that the headrest moves the opposite way of the front seat control switch input and/or the front seat control switch hot keys are inoperative. This may be due an incompatibility between the seat switches, headrest, and software in the driver front seat module (DSM) and/or the passenger front seat module (SCMB). To correct the condition, follow the Service Procedure to verify the correct parts are installed in the vehicle and the software is correct.
