failure radar, error message FCA and SCC

Hello, last weekend it was a bit stormy and partly snowy. I was on the highway when it got quite wintery and it started to snow. The snowfall was at some point quite strong, but there was not much left on the road. After some time at weather-related speed 50 – 70 the radar was snowed in at the front, so that I got the message that the FCA (front collision warning) does not work, a little later came still the gleic he message for the SCC (Smart Cruise Control). It’s also logical, since this also uses the distance radar. Everything is OK, can happen in the weather. When I was at home, I released the front including the radar plate from the snow and started the car. Funny way I still got the same error messages to the FCA and SCC. OK, then wait until the next day. Tags on it: storm past, no snow, 5 degrees. Unfortunately still these messages. A short Fa The manual says that you have to contact the KIA service partner with these messages. My first thought: Yes great, now the radar broke because of such a bit of snow? That can’t be something. Anyway, I made an appointment in the workshop, which would then be next week. Today I was again briefly in the supermarket, and on the way back the error messages were suddenly gone. Did the car turn right and started again if the messages are actually gone: Yes, obviously everything works again. SCC works again anyway. So apparently it had to be found again after the snow was no longer on the plate. Of course I will delete the workshop appointment again, because the messages have disappeared. Maybe someone had an experience with the radar, e.g. in the case of snowfall?
