SummaryCUSTOMER SATISFACTION CAMPAIGN: OWNER NOTIFICATION (CS2312) - This document is the owner notification advising that Kia is conducting Customer Satisfaction Campaign. A software upgrade that addresses the social media theft method has been made available to owners of eligible Kia model vehicles free of charge at authorized Kia dealers since 2023. In addition to the anti-theft software, a new zinc-reinforced ignition cylinder protector hardware upgrade has been developed and can be installed at the ignition cylinder location to provide additional protection against the social media theft method. Because the subject Kia vehicles were not factory-equipped with an engine immobilizer and were previously eligible for the software upgrade, these vehicles are eligible until March 31, 2027, to have the ignition cylinder protector installed—if requested—at no cost through an authorized Kia dealership. (Mailing of these notifications to vehicle owners will be completed from December 17, 2025 through February 27, 2026)

SummaryPITSTOP: 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.)
