Temporary radar failure

[Philip2]

About twice a week my radar fail warning comes on for about 2 to 3 minutes and then goes off on its own. It consists of three letters which I do not recall at this time. We're talking about a 2015 G80 I bought used two years ago

Sometimes this is in rain, but usually not. It sometimes relates to fog or just polluted Los Angeles air, but often goes off when the air seems pretty clear and I can see distance fairly well. It doesn't seem to happen in crystal-clear conditions

Is this normal? Why does it happen if the air seems pretty clear?

Semi-normal. Heavy rain, snow, or anything that blocks the signal will turn it off. Never had it happen in clear weather. Even a modest amount of winter dirt did not seem to bother it.

I live in LA and never have this problem so I would say NO your experience is not normal.
