Common questions
Source: NHTSA, 49 CFR 579.5Is Kia SC369 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 SC369 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 SC369 cover?
The manufacturer filed it against 2 model years: 2023 Kia Stinger, 2022 Kia Stinger. 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: 2022-2023 MY Stinger: built 1 Feb 2021 – 11 Apr 2023 — the build date is on the certification label in the driver’s door jamb.
