39 Battery problem of the 2004 Toyota Prius

Failure Date: 04/08/2005

Driving my 2004 Toyota Prius home from work, the car suddenly lost power a few miles from my home on a busy thoroughfare. I drifted to the side of the road. All warning lights on the dash were on. I turned off the car and restarted it. It went a few seconds before dying again. This continued several times until I made it home. The incident caused other cars to have to slow down, honk and move around me. I was very scared. It was late at night. I called my husband to come help me but he was not home. The next day the car started and I took it to the dealership. They could find nothing wrong, and said they "reset the engine/battery ratio" so the car would rely more on gas than electricity , and that I would experience a slight decrease in my engine efficiency. I later complained to the service manager, that my Prius has had numerous electrical problems since I purchased it in August of2005. Twice it would not start in the morning and I had to have it towed. He also told me that what the service person told me was incorrect, that there was no way they can "adjust" the engine/battery ratio. He gave no explanation for my problems and said "no one else" has had any problems with their cars. I want to return the car for a new one, but he says he feels "confident" Toyota will correct any problems I am having. I am afraid to drive the car in case this happens again. Toyota has done nothing since I have complained. I feel they owe me a new car while they figure this out.
