I purchased a 2002 Toyota Prius in April 2002 and within the first two months the vehicle stopped while on the freeway at 65+ mph and the gas engine would not work, I had to drive on the electrical motor. It was repaired at the Toyota dealer in carlsbad, CA. This is the same issue that was reported in the press today.
