Kia bulletin SA601
Kia filed this with NHTSA as a over-the-air update dated Feb 26, 2025, received Jan 23, 2025, about the electrical system — 3 documents under this number: TSB_ELE369_R1, OTA_SA601, TSB_ELE369. It names 2 model years (2024–2025). A over-the-air update is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SA601 a recall?
No. A over-the-air update 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 SA601 repair free?
A over-the-air update is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does SA601 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.
