Camera system does not work sometimes or only some of the cameras work sometimes. Dealer agrees there is a problem, but no fix is currently available. I have noted that other 2022 Audi A6 models have been recalled for this reason. The problem first occurred about 2 months ago. Sometimes the cameras are working and sometimes you get a black screen or a partial black screen. The problem is that when the cameras don't work, you also don't get a visual indication of cross traffic when backing out of a parking space.
