Electric Vehicle EV charging error accompanied by DTC P343B16 on certain 2025-2026MY EV6 (CVa) and 2026MY EV9 (MVa) vehicles equipped with Combined Charging System Combo 1 (CCS1, also known as SAE J1772 Combo) charging ports. When using the wrong CCS1 to North American Charging Standard NACS adapter, proper electrical connections are not made between the charger to adapter and adapter to vehicle charging port, resulting in a charging error which can cause DTC P343B16 to set. Non-OEM adapters may not set the DTC P343B16.

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 replace the 3-way coolant valve. In addition, inspect the 3-way coolant valve harness connector for corrosion, and if necessary, replace the harness connector on certain 2024-2026MY EV6 (CV, CVa) vehicles produced from August 07, 2023 through June 18, 2026. The 3-way coolant valve in the subject vehicles may become damaged and result in a coolant leak. As a result, corrosion may also be present in the 3-way coolant valve harness connector. An inoperative 3-way coolant valve or corrosion within the harness connector may result in reduced Heating, Ventilation, and Air Conditioning (HVAC) performance and/or in the illumination of the Check electric vehicle system or Refill Coolant warning messages in the instrument cluster.

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.)

(SC343) - 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 upgrade the Powernet Domain Control PDC system software on certain 2025MY EV6 (CV1a) vehicles produced from December 10, 2024 through June 24, 2025, built at a Kia assembly plant in the US. Due to a PDC software logic error in the subject vehicle, the pre-charge resistor may become damaged if the vehicle is abnormally turned OFF (e.g. turned OFF while the gear selection is in Neutral). If the pre-charge resistor becomes damaged, the vehicle may not go into READY mode. Customers may experience the illumination of the service warning light, and the vehicle may set DTC P1B7700. If DTC P1B7700 is stored, technicians are to replace the PRA before upgrading the PDC software.
