VOLUNTARY EMISSIONS SERVICE CAMPAIGN: OWNER NOTIFICATION (SC357) - This document is the owner notification advising that Kia is conducting a Voluntary Emissions Service Campaign to improve the emissions software logic in the Electronic Control Module (ECM) for 2020-2025 MY Telluride vehicles to ensure compliance with emissions regulations.
SC325_TSB_R12026-02-26. Service bulletin. TECHNICAL SERVICE BULLETIN: VOLUNTARY EMISSIONS SERVICE CAMPAIGN: AEWP INSPECTION AND REPLACEMENT (SC325) - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information to inspect and, if necessary, replace the Auxiliary Electric Water Pump (AEWP), control harness wiring, and/or engine room junction box for coolant intrusion and/or corrosion on certain 2022-2023MY Kia Hybrid and Plug-in Hybrid vehicles listed in the table below. The AEWP in the subject vehicles may crack internally and allow coolant to intrude into the AEWP circuitry. If coolant enters the AEWP circuitry, the Check Engine Light (CEL) may be illuminated with one or more DTCs listed on page 2. If the vehicle continues to be driven in this condition, the Active Air Flap (AAF) warning message can also activate, and coolant may eventually migrate through the wiring harness to the engine room junction block. This may result in a reduction of motive power and may cause the vehicle to release air pollutants which exceeds Federal and California standards. These standards were established to protect the public health and welfare from the dangers of air pollution.
