Was driving in the rain at 8:30PM and lost headlights, had to keep high beams on all the time to drive home, took back roads where their was less traffic to keep lights on, it ticked-off other drivers coming at me, but had no choice. Had just gone shopping and had a car full of frozen goods. Don't know if this is same problem Toyota Prius owners are experiencing. Will see what the dealer tells me Monday morning. This is first problem I have had with a Toyota, but it is a beauty. Wife needs car daily to take mother for kemo treatment for cancer.
