Will take photo of dash next time it happens, which is only sporadically. The No Eyesight diagram appears with a slash through it so one knows it's not operating, but it is not clear what causes it. Sometimes it's while driving in rain, but the rain is not so hard that it should cause the function to fail. Hadn't reported it to the dealer service department because it is on periodic, doesn't come to mind at the time, and was unaware that others may have the same issue. Since the "Eyesight" feature/cameras are an added cost for this model, it is truly annoying when it malfunctions and doesn't provide the safety features it's supposed to do. It is also a distraction while driving.
