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.

Parking Distance Warning (PDW) alerts and repairs involving ultrasonic sensors. The PDW system alerts the driver while parking, by calculating distance based on the difference in signal transmission and reception times between the vehicle (ultrasonic sensor) and an object. The membrane film of the ultrasonic sensor is used for object detention and can be damaged by stone chips or foreign substances while driving. Damage to the cover of the ultrasonic sensor can also lead to damage to the internal circuit. As a result of this external damage, the PDW system may not receive the proper signal from the ultrasonic sensor. In some cases, the system may cause a false alarm, no alert, or phantom warnings by a Warning Lamp to be displayed on the cluster. The ultrasonic sensor membrane film should be always inspected for external damage and if any part replacement should be treated as a general repair, not as a warranty claim repair for this concern. (Please note that this Pitstop only applies to models/trims that are equipped with the ultrasonic sensors.)

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 the procedure to update the software logic of the Hybrid Control Unit (HCU) system on certain 2023-2025MY Sportage HEV (NQ5 HEV) vehicles produced from February 15, 2022 through July 25, 2024 and Sportage PHEV (NQ5 PHEV) vehicles produced from June 16, 2022 through July 24, 2024. The Hybrid Control Unit (HCU) in the subject vehicles may intermittently receive repeated accelerate CAN signals due to a signal processing error involving specific instrument clusters when customers set or resume cruise control. This concern can occur after the driver rapidly presses the accelerate rocker switch on the steering wheel. This does not affect the drivers ability to pause, cancel or turn off the cruise control function. This condition 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.
