I purchased a 2018 CR-V 4 weeks ago. When attempting to understand the operation of the electronics I somehow managed to mess with the clock. The semi colon flashes but the time is correct. Took it to the dealership yesterday and they told me they checked 2 other CR-V's and they do the same thing. They didn't seem to want to believe me that it wasn't doing this when I purchased it and that it started 3 weeks after I brought it home. There is also a little icon that flashes for a few seconds which they tell me is the satellite icon and it stops flashing when a station is found. I thought maybe this would be a good place to get an answer since the dealership blew me off. It certainly isn't affecting performance. It's just annoying.
