Porsche TSB #122-G6X5S-04
2017 Porsche Panamera
Affected Component: ELECTRICAL SYSTEM
- Subject: Control unit for high-voltage charger Information: Due to a software error, there is a possibility that the control unit for the high-voltage charger will not switch to energy-savingmode after the vehicle is stopped in the event of specific user behavior. This can result in an increased closed-circuit current load and can thus deplete the vehicle electrical system battery.
