Kia filed this with NHTSA as a service bulletin dated Apr 15, 2024, received May 6, 2024, about the exterior lighting. It names 1 model year (2024).

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: INTEGRATED LED HEADLAMP CONTROL UNIT OPERATION LOGIC IMPROVEMENT (SA567) - This bulletin provides information to upgrade the software on the Integrated LED Headlamp Control Unit 'ILCU' on certain 2024MY EV9 (MV) vehicles produced from September 25, 2023 through January 25, 2024. The ILCU can switch from 'standby mode' to 'active mode' potentially causing the 12V auxiliary battery to discharge while the vehicle is parked. If this occurs, the vehicle might not be able to be started.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 212 complaints with NHTSA since 2015. 106 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The vehicle digital instrument cluster turned off and wouldn’t show speed or any other information. The central infotainment screen and the climate control screen worked while driving. The turn signals were not working while this was happening either.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia TSB_ELE336 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_ELE336 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_ELE336 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 25 Sep 2023 – 25 Jan 2024; EV9 (MV): built 25 Sep 2023 – 25 Jan 2024 — the build date is on the certification label in the driver’s door jamb.
