I'm getting that message while driving in the rain a lot. Probably 12 times this morning while driving 65-75 mph. Not hard rain but not drizzle either. I just cleaned the cameras the other day. Is anyone else experiencing this? My previous Model 3 which I had for 18 months never got this message, but it was also on HW 2.5. Is it possible that is it misaligned and a raindrop is obscuring it? Or maybe glare from some other car's headlights? Should I make a service appointment?
