08-001-232023-03-03. Service bulletin. SEAT BELTS; SEAT BELTS:STATUS INDICATOR SWITCH; FORWARD COLLISION AVOIDANCE; ELECTRICAL SYSTEM; SEATS. Some vehicles may turn on the passenger seatbelt reminder, even though there is no passenger seated in the vehicle. This concern may be caused by the passenger sensor being too sensitive. To eliminate this concern, the passenger sensor has been modified.
15-002/222022-02-04. Service bulletin. ELECTRICAL SYSTEM:ADAS:PARKING ASSIST:SENSORS; ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:ADAS:PARKING ASSIST:WARNING; FORWARD COLLISION AVOIDANCE: SENSING SYSTEM: CAMERA; EQUIPMENT; FORWARD COLLISION AVOIDANCE. Some vehicles may exhibit either or both of the following symptoms. 1. The SCBS warning light is illuminated with DTC U045A:68 [FORWARD SENSING CAMERA (FSC)]. U045A:68 Error signal received from parking assist unit 2. The parking sensor indicator is flashing with one or more of the following DTCs of PARKING ASSIST SYSTEM. B1B36:14 Front corner ultrasonic sensor (RH) circuit malfunction B1B36:2A Front corner ultrasonic sensor (RH) characteristic malfunction B1B38:14 Front ultrasonic sensor (RH) circuit malfunction B1B38:2A Front ultrasonic sensor (RH) characteristic malfunction B1B40:14 Front corner ultrasonic sensor (LH) circuit malfunction B1B40:2A Front corner ultrasonic sensor (LH) characteristic malfunction B1B42:14 Front ultrasonic sensor (LH) circuit malfunction B1B42:2A Front ultrasonic sensor (LH) characteristic malfunction Due to insufficient waterproof performance of the front harness short cords (1), water may enter in and accumulate in the C-11 (LH) or C-12 (RH) connectors (2) causing a short circuit between wires and an improper signal being sent from the parking (ultrasonic) sensor to the parking sensor unit. To eliminate this concern, the production process of the front harness short cord has been improved to increase waterproof performance.
15-001/222022-02-04. Service bulletin. LANE DEPARTURE: BLIND SPOT DETECTION; LANE DEPARTURE; ELECTRICAL SYSTEM; EQUIPMENT. Some vehicles equipped with Blind Spot Monitoring (BSM) may experience a BSM indicator light on the outer door mirror, even if there is no vehicle in the alert (blind spot) area. NOTE: This concern occurs only after a cold start. As the BSM control module temperature rises, the BSM system returns to normal operation. Due to BSM control module production variances, a false detection may occur in some units when the BSM temperature in the control module has not yet reached normal operating temperature. To eliminate this concern, the control logic of the BSM control module has been modified.

09-033-19-35902019-08-21. Service bulletin. BACK OVER PREVENTION. Some vehicles may exhibit the rear parking sensor beeping without any obstacles behind it when the shift lever is shifted into Reverse. This concern only occurs when the rear USB power outlet (1) is broken. This is caused by noise from USB interference with the harness of the rear parking sensor (when the USB power outlet is broken).To correct this issue, the configuration of the USB power outlet has been changed to improve durability.
09-032-19-35792019-08-21. Service bulletin. BACK OVER PREVENTION. Some customers may experience improper operation of the rear parking system with beep sounds coming from the rear parking sensor when there are no obstacles behind the vehicle. This occurs when the blower fan is on (at any fan speed) and the transmission is in "R" position. The concern is caused by electrical noise from the blower fan controller circuit affecting the rear parking sensor circuit. To eliminate this concern, the harness to the rear parking sensor has been twisted to improve its tolerance to electrical noise.
