Kia filed this with NHTSA as a service bulletin dated Jan 8, 2024, received Feb 2, 2024, about the seats. It names 1 model year (2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia TSB_ELE326 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the TSB_ELE326 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Kia warranty extension on file lists the ones Kia has filed.
Which vehicles does TSB_ELE326 cover?
The manufacturer filed it against 1 model year: 2024 Kia EV9. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2024MY EV9 (MV): built 24 Sep 2023 – 6 Nov 2023; EV9 (MV): built 24 Sep 2023 – 6 Nov 2023 — the build date is on the certification label in the driver’s door jamb.
