- Summary
- TECHNICAL SERVICE BULLETIN: SERVICE ACTION: POWER SEAT MODULE OPERATION LOGIC IMPROVEMENT (SA557) - This bulletin provides the procedure to update the software logic of the Power Seat Module (PSM) system on certain 2024MY EV9 (MV) vehicles produced from September 24, 2023 through November 6, 2023 to improve the front seat Easy Assist and Leg Rest operation, preventing the driver's leg rest from extending while driving. In addition, the software also improves the logic of the cargo area power folding seat buttons, so that the left seat will fold partially if the front row seat is too far back, which is the existing logic for the right seat.
Owners of these vehicles have filed 11 complaints in the seats category.
