It usually means that one of your cameras is blocked. No need to reset the car, it will go away.Never had it before until we had rain the other day, but I’ve only had Luci for about a month now. It rained for 3 days and I had the yellow triangle the entire time.
First time i saw it, I did a logo rest and it went away. I didn’t bother when it came back on the next day. It stopped raining today, so hopefully it won’t come back or if I do a logo reset it will stay away.
Since it went away on the logo reset, I just think it was nothing serious.
