- [122\-B7U4T\-05](/bulletins/10119291.md), 2017-10-15, Service bulletin: ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Customer Concern: Certain vehicle systems have unwanted, unpredictable behavior. Technical Concern: The symptoms are difficult to diagnose. There may be multiple symptoms intermittently affecting multiple systems. Though this is not an exhaustive list, some common failure modes are: ? Start/stop issues ? Power windows not fully returning to the parked position after automatic preopening ? PCM audio stopping during a start/stop cycle Ultimately, the technician determines that low 12\-volt battery voltage is the underlying root cause of the unwanted behavior. The technician corrects the battery?s low voltage. Consequently, the unwanted behavior ends.
- [122\-W8J3S\-09](/bulletins/10117509.md), 2017-09-14, Service bulletin: ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Technical Concern: Porsche designs plug\-in hybrid vehicles to protect the health of the high voltage battery. One way the vehicle does this is by disabling high electrical load features when the high voltage battery has a low state of charge.
