Quick answer

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.)

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
