Why would the dashboard lites not come on & the car will not shut off when wet? on 2008 Toyota Prius

On occasion, after a few days of heavy rain the dashboard lights do not come on and the car will not shut off until it really warms up. Seems to be it must be a sensor or wire that is effected until the car warms up/dries out. Car runs fine. This morning it happened again--just with colder weather (no rain). Thanks!

Take it to the dealer and get them to check it for you. It will save you some bucks in the long run!
