If you are asking if it would disappear, if my guess is right yes it would. Washing/cleaning the front of the car may help, that's where the sensors are. If they are dirty the rain may be just enough for them not to be able to see....Yes it is under warranty. Is the any case to disappear ?
I think you should bring it in, show them the pics you took and let them diagnose it. I didn't get from your first post the car died I thought only some sensors turned off. Especially if the car stopped running go for warranty service.After 3 hours i started up again and no problem. It is ok. What can i say
