Passenger car (Hyundai INSTER) - Repair

An official CAA Japan notice concerns Passenger car (Hyundai INSTER) - Repair. Defect in the motor cooling system coolant 3-way valve. Defective component: Motor cooling system coolant 3-way valve. Condition of the structure, equipment or performance considered noncompliant with standards, and its cause: Insufficient design evaluation of the motor cooling system 3-way valve can cause: ① Excessive stress on the drive shaft of the valve's internal components, resulting in damage. ② The circuit protection fuse capacity is too high, so the circuit may not be interrupted properly in the event of an electrical short circuit, resulting in abnormal heat generation. Consequently, if coolant leaks from the damaged drive shaft area and enters the motor control unit, the abnormally hot electrical circuit heats it and generates steam. Continued use may restrict motor output and, in the worst case, make the vehicle unable to drive. Note: The 3-way valve switches the coolant flow paths within the motor cooling system. Published 2026-07-23.
What to do now
Recall notification number: 外-4212. Corrective measures: On all vehicles, replace the 3-way valve and electrical circuit fuse with modified parts. Also inspect the 3-way valve connector and, if coolant ingress is confirmed, repair the connector appropriately.
