Kia bulletin SC322
Kia filed this with NHTSA as a emissions communication dated Jan 30, 2025, received Jan 16, 2025, about the electrical system — 8 documents under this number: TSB_SC322_R1, SC322_OWNR, SC322_DPSM, SC322_DP and more. It names 3 model years (2023–2025). A emissions communication 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 communicationTECHNICAL SERVICE BULLETIN: VOLUNTARY EMISSIONS SERVICE CAMPAIGN: HYBRID CONTROL UNIT (HCU) LOGIC IMPROVEMENT (SC322) - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides the procedure to update the software logic of the Hybrid Control Unit (HCU) system on certain 2023-2025MY Sportage HEV (NQ5 HEV) vehicles produced from February 15, 2022 through July 25, 2024 and Sportage PHEV (NQ5 PHEV) vehicles produced from June 16, 2022 through July 24, 2024. The Hybrid Control Unit (HCU) in the subject vehicles may intermittently receive repeated “accelerate� CAN signals due to a signal processing error involving specific instrument clusters when customers “set� or “resume� cruise control. This concern can occur after the driver rapidly presses the “accelerate� rocker switch on the steering wheel. This does not affect the driver’s ability to pause, cancel or turn off the cruise control function. This condition may cause the vehicle to release air pollutants which exceed Federal and California standards. These standards were established to protect the public health and welfare from the dangers of air pollution.

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 Kia SC322 a recall?
No. A emissions communication 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 SC322 repair free?
A emissions communication 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 SC322 cover?
The manufacturer filed it against 3 model years: 2025 Kia Sportage, 2024 Kia Sportage, 2023 Kia Sportage. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
