Kia America, Inc. has initiated a Voluntary Emissions Service Campaign, identified as SC340 FLT 103, to address the emissions software logic in certain 2017-2022 MY Sportage vehicles. This campaign specifically targets vehicles equipped with 2.4L Gas Direct Injection (GDI) engines.
The primary goal of this campaign is to improve the emissions software logic within the Electronic Control Module (ECM). This update is necessary to ensure that the affected vehicles comply with current emissions regulations.
Why This Matters
Kia has identified that certain 2017-2022 MY Sportage vehicles, particularly those with 2.4L GDI engines, may have engine calibrations that are not optimally configured for emissions standards under specific conditions. These calibrations could lead to the vehicle releasing air pollutants that exceed Federal and California standards.
Such non-compliance poses a risk to public health and welfare due to the dangers of air pollution. The Kia Sportage emissions software update is critical for environmental protection and regulatory adherence.
What's Being Updated
The campaign involves updating the software programming of the Electronic Control Module (ECM). This update will enhance the emissions-related logic, bringing the vehicles into full compliance with established environmental standards.
Manufacturer's Remedy
Kia will perform this essential software update free of charge to vehicle owners. There will be no cost to you for this service.
Important Warnings for Owners
Owners should be aware of several critical points regarding this Voluntary Emissions Service Campaign:
- "Failure to have this service performed could cause your vehicle to fail an emissions inspection (SMOG check) when required under State law. It could also be considered a lack of proper maintenance."
- For California registered owners, the California Air Resources Board mandates that emissions-related campaigns like this must be completed before annual vehicle registration renewal. Without this software update, you may be unable to complete your vehicle registration and obtain license tags.
- Following the software update, your Kia dealer will provide a "Proof of Correction Certificate." This certificate may be requested by the California Department of Motor Vehicles (DMV) or similar agencies in states that have adopted California emissions regulations (e.g., Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, or Washington) during your next vehicle registration. It is important to keep this certificate with your vehicle records.
Owner Action
To address the Kia Sportage emissions software issue, you should contact an authorized Kia dealership to schedule a service appointment for this update. While the actual software update may take less than an hour, the total service time can vary based on the dealer's schedule. Scheduling an appointment in advance is recommended to minimize inconvenience.
Performing this campaign will also help ensure your vehicle's full protection under its emissions warranty. If you have questions or your dealer does not respond to your service request, you can contact Kia's Customer Care Center at 1-800-333-4542 (Monday through Friday, 5 AM to 6 PM, Pacific Time) or visit https://customercare.kiausa.com.
