Kia service campaign SC323

Kia filed this with NHTSA as a service campaign dated Oct 31, 2024, received Oct 30, 2024, about the electrical system — 5 documents under this number: SC323_OWNR, SC323_TSB, SC323_QA, SC323_DPSM and more. It names 2 model years (2023–2024). 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 communication

TECHNICAL SERVICE BULLETIN: VOLUNTARY SERVICE CAMPAIGN: VCMC LOGIC IMPROVEMENT (SC323) - This bulletin provides information to improve the software logic in the Vehicle Charging Management System (VCMS) on certain 2023-2024MY Niro EV (SG2 EV) vehicles produced from July 11, 2022 through February 23, 2024. While charging using a 240-V AC (“Level 2�) charger, the subject vehicles may experience an interrupted charging session or a lower charging speed due to a degraded electrical connection from exposure to a damaged charging cable connector. Dealers are to update the ‘VCMS’ ECU with improved software to improve charging speeds and reduce interrupted charging sessions.

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 SC323 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 SC323 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 SC323 cover?

The manufacturer filed it against 2 model years: 2024 Kia Niro, 2023 Kia Niro. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
