What it saysCertain Kona (SX2) vehicles may exhibit a dead battery concern linked to the Multimedia Keyboard (MKBD) logic. NHTSA’s full summary ↓
Hyundai filed this with NHTSA as a service campaign dated Feb 19, 2025, received Dec 14, 2024, about the electrical system — 2 documents under this number: 25-01-012H TSB, 24-01-090H. It names 2 model years (2024–2025). A service campaign 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.

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.
Certain Kona (SX2) vehicles may exhibit a dead battery concern linked to the Multimedia Keyboard (MKBD) logic. The MKBD may not enter sleep mode when the vehicle is turned OFF, causing the battery to be drained. Follow the procedure in this TSB to update the software for the MKBD to address this condition.

Read by machine from the document NHTSA serves (6 pages), read Sep 30, 2026. A part number is shown only where it matches Hyundai’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. 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 Hyundai TCL a recall?
No. A service campaign 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 TCL repair free?
A service campaign 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 TCL cover?
The manufacturer filed it against 2 model years: 2025 Hyundai Kona, 2024 Hyundai Kona. 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: built 19 Jun 2023 – 7 Sep 2024 — the build date is on the certification label in the driver’s door jamb.
