Kia bulletin SA644

Kia filed this with NHTSA as a service bulletin dated Jul 2, 2026, received Jul 28, 2026, about the fuel/propulsion system — 1 document under this number: TSB_ELE416. It names 1 model year (2023). 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 communication

TECHNICAL SERVICE BULLETIN: ON-BOARD CHARGER INSPECTION AND REPLACMENT (SA644) - This bulletin provides information related to charging system diagnosis and repair on certain Sportage (NQ5 PHEV) vehicles produced from December 13, 2022 through May 30, 2023. The affected vehicles may experience interrupted or inoperative high‑voltage battery charging due to an on‑board charger (OBC) internal malfunction. As a result, charging of the high-voltage battery may be interrupted or unavailable, with several diagnostic trouble codes (DTCs) stored related to the OBC unit. If this occurs, the vehicle can still be driven by the internal combustion engine.

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 579.5

Is Kia SA644 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 SA644 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.

Which vehicles does SA644 cover?

The manufacturer filed it against 1 model year: 2023 Kia Sportage. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
