Rear right light got water in it after washing the car and the electrical wires shot out and car went on fire. Firefighters came and investigated and came to this conclusion. Car was totaled and insurance company took pictures and wrote report. Car will be towed by insurance company today. Car was in driveway next to house, we saw smoke from window and fire was extinguished quickly but it was fortunate that we were home and saw it in time so it did not spread anywhere else. Car had not been driven for 2 days and was not on, no warning lights in past. No accidents in past, all maintenance done by Toyota dealer.
