Kia bulletin SA608
Kia filed this with NHTSA as a over-the-air update dated Mar 4, 2025, received Mar 5, 2025, about the electrical system — 2 documents under this number: TSB_ELE375, OTA_SA608. 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SA608 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 SA608 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 SA608 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.
