Torque your drain plug to 35 Nm (26 ft-lbs) to avoid leaks or stripped threads. Using the OEM filter (Kia 26300-35505) is recommended for warranty compliance.

PITSTOP: TECHNICAL OPERATIONS: EXTERNAL DAMAGE TO ULTRASONIC SENSOR: This Pitstop provides information related to 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.)

TECHNICAL SERVICE BULLETIN: SERVICE ACTION: STEERING ANGLE SENSOR CALIBRATION (SA641) - This bulletin provides information regarding the recalibration of the Steering Angle Sensor (SAS) on certain Seltos (SP2 PE) vehicles produced from March 3, 2025, through August 11, 2025. During manufacturing, the SAS in certain vehicles may not have been properly calibrated, resulting in a lower return-to-center feel after completing a turn at low speeds. This does not result in a reduction of steering assist.
