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.

What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 263 complaints with NHTSA since 2015. 79 of them name Electrical System, Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The contact owns 2022 Kia Carnival LX. The contact stated that while driving at 55 MPH, the engine misfired, and the check engine warning light was illuminated. In addition, the vehicle would shudder when warming up. The vehicle was driven to local repair and diagnosed several times with the same failure, but not repaired.

Purchased new KIA Carnival in May 2024. In August 2024 ALL of the warning lights came on and started cycling through to check every system. The warnings were the only thing that worked on the instrument cluster. All of the analog instruments stopped working: the speedometer, the tachometer, the fuel gauge, etc..

We drove an hour then sat in the car while it was on for about 30 minutes. The gas tank was 14% full. We started driving again down a bit of a hill & got to a stop light. The car started beeping & said “engine off! Switch to N then start engine” We turned the car off and back on & it started working

Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SC290 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 SC290 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 SC290 cover?
The manufacturer filed it against 3 model years: 2024 Kia Carnival, 2023 Kia Carnival, 2022 Kia Carnival. 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: 2022-2024 MY Carnival: built 4 Jan 2021 – 6 Nov 2023 — the build date is on the certification label in the driver’s door jamb.
