Why This Matters: Emissions Compliance

Kia America, Inc. has initiated a Voluntary Emissions Service Campaign for certain 2023 Kia Sportage vehicles. The campaign addresses a potential issue with the fuel filler neck vent collar that could lead to the release of air pollutants. If the vent collar port is partially blocked, the vehicle may exceed Federal and California emissions standards. These regulations are crucial for protecting public health and welfare from the dangers of air pollution, making the proper function of the Kia Sportage fuel filler neck vent collar essential.

What's Being Addressed

This campaign focuses on the fuel filler neck vent collar in 2023 Kia Sportage models manufactured between November 17, 2022, and January 18, 2023. Kia has identified that some vehicles within this production range may have been equipped with a vent collar that does not meet U.S. EPA regulations. A partially blocked vent collar port can compromise the vehicle's emission control system, potentially causing the vehicle to release excess air pollutants.

Inspection and Remedy

Dealers will inspect the fuel filler neck vent collar on affected 2023 Kia Sportage vehicles. If the vent collar port is found to be partially blocked, the fuel filler neck vent collar will be replaced. This inspection and any necessary replacement will be performed at no cost to the customer, ensuring compliance with emissions standards.

Technical Service Bulletin Details

A Technical Service Bulletin (TSB) providing detailed vehicle repair procedures, the affected VIN production range, and warranty claim information will be posted on the Kia Global Information System (KGIS) at www.kiatechinfo.com. This TSB will be available during the week of July 5, 2023, serving as the primary guide for dealer technicians to address the Kia Sportage fuel filler neck issue.

Owner Notification and State-Specific Requirements

Owner notification letters regarding this campaign will be mailed starting July 7, 2023. These letters will include a Q&A guide to help owners understand the campaign. For owners in California, Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington, a completely filled-out "Proof of Correction Card" must be provided upon completion of the campaign. This card may be required for vehicle registration renewal in these specific states. Owners should ensure they receive this card from their dealer if they reside in one of these states. "Campaign Completion Labels" and "Proof of Correction Cards" are specifically for California and S.177 State dealers and can be ordered through the PDC.
