Kia filed this with NHTSA as a service bulletin dated Apr 22, 2025, received Apr 23, 2025, about the fuel/propulsion system. It names 2 model years (2024–2025). 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: VEHICLE-TO-EVERYTHING (V2X) SOFTWARE UPGRADE - This bulletin provides information to install the Vehicle-to-Everything ‘V2X’ function enhancements by upgrading the software of the Vehicle Charging Management System ‘VCMS’, Rear Motor Control Unit ‘R_MCU’, Vehicle Control Unit ‘VCU’ and Battery Management Unit ‘BMU’ systems on some 2024-2025MY EV9 (MV1) vehicles produced from September 25, 2023 through October 15, 2024, that have been unable to be updated using the Over-The-Air (OTA) method. The V2X technology allows EV9 vehicles to interact with other devices such as Vehicle-to-Home ‘V2H’ and Vehicle-to-Grid ‘V2G’ technology which enables bidirectional charging, where the EV's battery can be used as a mobile energy storage unit, providing power to the grid or a home backup power source.

My 205 EV9 Wind with 24500 Miles left me stranded, the standard battery simbol that in ICE cards refers to the alternator, came on, I tried to get to the dealer about 20 miles in the way home, less that 3 miles after that the car lost power with just enough to move to the shoulder, I stopped, power the car off and tried turning it back…

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia TSB_ELE380 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_ELE380 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_ELE380 cover?
The manufacturer filed it against 2 model years: 2025 Kia EV9, 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: 2024-2025MY EV9 (MV1): built 25 Sep 2023 – 15 Oct 2024; EV9 (MV1): built 25 Sep 2023 – 15 Oct 2024 — the build date is on the certification label in the driver’s door jamb.
