procedure to replace the Drive Mode button cover on certain 2025MY Carnival HEV (KA4 HEV) vehicles produced from August 23, 2024 through October 19, 2023, which may exhibit a stuck or sticky Drive Mode button operation. Due to variations in ambient temperature, the Drive Mode button cover material may expand or contract, preventing the button from returning to the default position.

information and service procedures for updating the infotainment systems on applicable Kia vehicles using the Kia Navigation Updater available at update.kia.com. The software update may improve system performance, enhance existing features, and apply the latest operating software for supported vehicles (2021-2026MY All Models).

stored on some 2025 - 2026MY Carnival (KA4, KA4 HEV) vehicles equipped with Connected Car Rear Cockpit ccRC rear seat entertainment screens. When performing a diagnostic scan using the Kia Diagnostic System KDS, DTC B281600 can become stored but does not cause any concerns with functionality of the ccRC system. DTC B281600 does not trigger any warning lights and does not indicate any hardware malfunction within the ccRC system and does not perform any meaningful diagnostic function. No further diagnosis, Techline case and/or repairs are necessary for DTC B281600 unless there is an active customer complaint of the ccRC system. This issue is expected to be resolved through a future ccRC Over-The-Air OTA update.

bulletin has been revised as a Combination TSB/SA and includes additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information to access the Dealer Mode function on 2024MY~ models listed on page 5 equipped with a Connected Car Navigation Cockpit (ccNC) head unit, and to perform a Reset Network and/or Factory Reset to address customer concerns related to activation of Kia Connect or Kia Connect features that may have stopped working.

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.)

New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information relating to the correct transmission fluid type and fill quantity requirement for each Kia model. A flush is required ONLY when a transmission is replaced, and the transmission oil cooler is transferred to the new transmission.

information to upgrade the Heating, Ventilation, and Air Conditioning (HVAC) control software on certain 2025-2026MY Carnival HEV (KA4 HEV) vehicles produced from May 16, 2024 through September 8, 2025, to prevent excessive discharging of the 12V battery by the Positive Temperature Coefficient (PTC) heater under certain operating conditions. When the engine is below operating temperature, the PTC heater is used to provide additional heat to the cabin. In very cold environments and under high electrical load, the PTC heater in the subject vehicles may discharge the 12V battery faster than it can charge. If the 12V battery becomes excessively discharged, the vehicle may enter Limp Home Mode with speed temporarily limited to a maximum of 31mph until the vehicle reaches normal operating temperature. There are no warning lamps or warning messages associated with this condition.

upgrade the Motor Control Unit MCU system software on certain 2025MY Carnival HEV (KA4 HEV) vehicles produced from June 27, 2024, through March 19, 2025. The affected vehicles may exhibit an intermittent Malfunction Indicator Lamp MIL illuminated on the instrument cluster with DTC P0C7300. The DTC is caused by a software logic error within the Integrated Thermal Management Module ITM, which controls the coolant flow rate according to the coolant temperature.

(PI2602) - This bulletin provides information to enhance the second-row seatback recliner mechanism to dampen the motion of the manual seatback angle adjustment during the operation on certain 2022-2026MY Carnival (KA4) produced from 1/4/2021 through 4/14/2026 and certain 2025-2026MY Carnival Hybrid (KA4 HEV) vehicles produced from 5/21/2024 through 4/8/2026. To aid in the manual adjustment of the outboard second-row seatback in the subject vehicles, the seats are equipped with recliner springs that work in conjunction with a user-controlled seatback angle lever or walk-in lever. This seatback motion is controlled by the user to achieve their desired seat position. To improve usability, Kia has developed a newly designed second-row seatback recliner spring that will dampen the motion of the manual second-row seatback angle adjustment. (Note: Only the second-row outboard seats are affected. The second-row center seat, if equipped, is excluded from this campaign.)

software update is designed to update the Data Connectivity Unit (DCU) logic of certain 2025 - 2026MY Carnival, 2025 - 2026MY K5 and 2025 - 2026MY Sorento vehicles. This update is designed to improve the vehicles network communication performance.

Data Connectivity Unit (DCU) system software on some 20252026MY vehicles listed in the table below. Kia has identified that Connected Car Services (CCS) functionality may intermittently fail due to temporary DCU communication issues. This condition can impact convenience and connectivity features by causing the Remote Start and Remote Climate functions to become inoperative, prevent vehicle status updates in the Kia Access app, and interrupt connected navigation routing services.
