122-W4G8S-102017-10-15. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ELECTRICAL SYSTEM. Technical Concern: By design, the vehicle gateway allows certain vehicle features to time-out, in stages. This allows the vehicle to sleep. One feature that can time-out is the 12 V DC power point (cigarette lighter) in the center console area. One of the recommended methods of using the battery maintainer is to plug the battery maintainer into this power point. If this power point becomes disabled, it will not allow current flow from the battery maintainer to the vehicle, the vehicle battery will not trickle charge, and the battery maintainer will eventually shut off.
122-W8J3S-092017-09-14. 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.
122-U5S5J-092017-09-14. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Information: During the packaging of a High Voltage Lithium Ion battery, copies of The test log for classification of lithium-ion high voltage batteries (located in PIWIS - Standard Forms) must be attached inside the box and to the document bag on the exterior of the box as per the Workshop Manual 2X00IN Packing non-critical high-voltage battery (970, 971, 92A) or Workshop Manual 2708IN Packaging instructions for high-voltage battery (918)
