You will need to take this one to the dealership or a shop capable of readin off all the control modules on your vehicle. What is most likely happening is that you have a control module causing a disturbance and bringing down the whole network on the low side CANbus or you have a problem in the wire harness where the green wire and white wire could be shorting out? Here is a typical network schematic of the vehicle.
The fault could be anywhere on the light grey side. The control modules look small on this picture but you have the Central Electronic Module which monitors all the control units, you have the SRS, the cClimate Control Module, Rear Electronic Module, Upper Electronic Module (rear view mirror) Driver and Passenger Door modules, Audio Module (radio) Passenger Seat Module, and depending on other options you have are the other modules and you can see the green and the white line connecting them which is the CANbus wires where data flows back and forth. So as you can see, it would be better to take it in to the dealership for proper diagnosis.
