Technical Service Bulletin SC325_DP — 2023 KIA SPORTAGE PHEV

VOLUNTARY EMISSIONS SERVICE CAMPAIGN: DEALER PRINCIPAL MEMO (SC325) - This document is the announcement to the dealer principals advising that Kia is conducting a Voluntary Emissions Service Campaign regarding the Auxiliary Electric Water Pump (AEWP) on certain 2023 MY Niro P/HEV, 2023 MY Sportage P/HEV, and 2022-2023 MY Sorento P/HEV vehicles. Kia has become aware that the Auxiliary Electric Water Pump (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. 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 drive power and may cause the vehicle to release air pollutants which exceed Federal and California standards. These standards were established to protect the public health and welfare from the dangers of air pollution.
