2024 Kia Carnival, Sportage, Niro EGR Valve Assembly Campaign

Kia America, Inc. has announced a Voluntary Emissions Service Campaign, identified as SC320, to address a potential issue with the Exhaust Gas Recirculation (EGR) valve assembly in certain 2024 model year vehicles. This campaign aims to ensure that all affected vehicles meet Kia's manufacturing specifications and comply with federal and California emissions standards.

Why this matters

The Exhaust Gas Recirculation (EGR) valve assembly plays a crucial role in controlling vehicle emissions by recirculating a portion of the engine's exhaust gas back into the engine cylinders. This process helps to reduce nitrogen oxide (NOx) emissions. If the Kia EGR valve assembly is not manufactured to proper specifications, it can lead to increased air pollutants being released into the atmosphere.

Beyond environmental concerns, a malfunctioning Kia EGR valve assembly can also trigger the "Check Engine light (CEL)" on the dashboard. This warning light indicates a potential problem with the engine or emissions system, which could affect vehicle performance and lead to failed emissions inspections.

Symptoms

Owners of affected vehicles may notice the illumination of the "Check Engine light (CEL)" while driving. This is the primary indicator that there may be an issue with the Kia EGR valve assembly or another component of the emissions system. While the document does not specify other symptoms, a faulty EGR valve can sometimes lead to rough idling, reduced engine performance, or increased fuel consumption.

What's being addressed

This campaign specifically targets the Exhaust Gas Recirculation (EGR) valve assembly. Kia has identified that some of these components may have been produced without adhering to the company's precise manufacturing specifications. The affected vehicles include:

• Certain 2024 MY Carnival vehicles manufactured from January 16, 2024, through May 2, 2024.
• Certain 2024 MY Sportage vehicles manufactured from January 17, 2024, through March 13, 2024.
• Certain 2024 MY Niro Hybrid (HEV) vehicles manufactured from January 23, 2024, through February 14, 2024.
• Certain 2024 MY Niro Plug-in Hybrid (PHEV) vehicles manufactured from January 23, 2024, through February 6, 2024.

Approximately 1,926 Carnival, 1,952 Sportage, 492 Niro HEV, and 173 Niro PHEV vehicles are included in this campaign, totaling around 4,543 vehicles. These vehicles were produced at Kia assembly plants in South Korea and the U.S.

Repair procedure summary

The resolution for this issue involves a straightforward replacement of the faulty component. Dealers will replace the existing Exhaust Gas Recirculation (EGR) valve assembly with a new one that meets Kia's manufacturing specifications. This ensures that the vehicle's emissions system functions correctly and prevents the illumination of the "Check Engine light (CEL)" due to this specific defect.

Owner action

Owners of affected 2024 Kia Carnival, Sportage, and Niro vehicles will be notified by first-class mail starting September 30, 2024. Upon receiving notification, it is recommended to contact an authorized Kia dealership to schedule an appointment for the service campaign. The repair, which involves replacing the Kia EGR valve assembly, will be performed free of charge to the customer.

The estimated time required to complete the replacement can range from one to three hours, depending on the specific model. However, the actual time may vary based on the dealer's work schedule. There are no restrictions on an owner's eligibility for this service campaign.

For any immediate questions or further information, customers can contact their local authorized Kia dealership or call Kia's Customer Care Center at 1-800-333-4KIA (4542), available Monday through Friday, 5 AM to 6 PM Pacific Time.
