noticed this a few times now after a jet wash the sensors don't seem to display but did fi dry area around sensors display works again.never had this with any other car I owned.i nearly Hit a wall expecting a warning on screen.
There is a batch of dodgy sensors that Tesla are aware of especially if its the front and not the front corners. Whether they can tell from the VIN or not I've no idea but a chat to your service centre may be needed.
