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.)

SummaryVOLUNTARY SERVICE CAMPAIGN: HVAC SOFTWARE UPGRADE FOR PTC OPERATION LOGIC IMPROVEMENT (SC352) - This bulletin provides 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.
