While driving on dry pavement at 35 mph the vehicle stalled. The consumer pulled off to the median. There were lights flashing in dashboard, the driver noticed that the warning codes included do not drive, and no brakes, etc. Just before stalling, the warning codes came on, including no brakes, do not drive, all hazards, the explanation pointed to a triangle and all precautionary safety warning lights appeared. Once the vehicle was stopped at a median there was no response from the car, it was totally dead. After the lights came on, no acceleration, there was no engine sound to the owner's knowledge. There was no obvious loss of power steering as far as the owner knew, it was not extremely difficult to get to the median. The vehicle was not able to be restarted. The owner tried to start the vehicle twice. At this point, the owner didn't know if the lights stayed on, but the hazards lights were working as she left to go call for help. At the dealership, the vehicle was jumped to get it off the tow truck. This occurred about 45 minutes. The dealer stated they had no idea what could be wrong with the vehicle, and this seemed to be a new occurrence to the dealership.

I own a 2004 Prius. While driving approx. 60 mph on hwy 110 in los angeles, the warning light came on. Less than 5 seconds later, the car lost all power. It even ceased to coast despite the fact that I was on a significant down hill grade. In an attempt to exit the freeway, I navigated the vehicle to the right, where it stalled completely in the right lane, blocking moving traffic. The California highway patrol (chp) quickly came (they were in the area and arrived without being called) and pushed the vehicle off the freeway. After waiting about 20 minutes, the car restarted and I drove for about 10 miles on surface streets. The next morning, I was able to drive one mile to the dealer. The service department of Toyota of hollywood, where I purchased the vehicle, said it was due to a "software glitch" and that it needed to be "reprogrammed." They completed this work in less than 24 hours. They also replaced the bumper which had been damaged by chp in the process of pushing the vehicle off the freeway. Their service was excellent and I have not had subsequent failures. Nevertheless, it was a serious malfunction and should be thoroughly investigated.
