An official CAA Japan notice concerns Passenger cars (Porsche Taycan and 5 other models) - Repair. Defect in the high-voltage system (high-voltage battery modules). ■ Defective part (component name): High-voltage system (high-voltage battery modules). ■ Condition of the structure, equipment or performance considered noncompliant with standards, and its cause: Some high-voltage batteries contain improperly manufactured battery modules. This may cause an internal short circuit in a battery module and, in the worst case, a heat-related battery malfunction that could lead to a fire. Published 2025-06-02.
What to do now
Recall: 外-4014. ■ Corrective measures: Inspect all vehicles via OTA or a dedicated diagnostic tester and replace any battery modules found to be abnormal with nondefective parts. Also install an updated program with vehicle self-diagnostic functionality via OTA or a dedicated diagnostic tester. However, because preparing the program will take time, as an interim measure, users will be asked to bring their vehicles in for regular battery inspections and will be informed to limit the charge level to 80％.
