Kia filed this with NHTSA as a service bulletin dated Mar 7, 2026, received Mar 13, 2026, about the fuel/propulsion system. It names 1 model year (2025).

Quoting the number at a service desk can save a diagnosis.

What the bulletin says

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia TSB_ELE392_R1 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_ELE392_R1 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_ELE392_R1 cover?
The manufacturer filed it against 1 model year: 2025 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: 2025MY EV9 (MV1a): built on or after 17 May 2024; EV9 (MV1a): built 17 May 2024 – 20 Dec 2024 — the build date is on the certification label in the driver’s door jamb.
