The surround video camera system frequently fails. One, several and sometimes all cameras randomly fail when triggered by placing transmission in reverse to park. Image is replaced by icon of camera with diagonal line through it. The dealer has attempted to fix this problem 4 times without success. They replaced all cameras and the video control unit. Many other owners of Porsche Cayenne, Macan and Taycans have reported this problem on various Porsche blogs. No one has reported a solution to the problem. The cameras are restored after turning off vehicle, leaving vehicle and locking vehicle. After waiting at least 15 minutes before rebooting vehicle, the cameras function normally. I have spoken to other Porsche dealers and none are aware of a solution to this problem. I have registered a complaint directly with Porsche and have not received any response in over 6 months.
