Consumer Description

I was driving my Toyota Sienna on a busy 6 lane highway in the second to the left lane, on a bridge. Suddenly without any warning AT ALL, my vehicle lost all power and came to an abrupt halt in the middle of high speed traffic. My wife and children were all in the car and we were in imminent danger of getting hit by another vehicle. It took the police approximately 10 minutes to arrive during which we were in life threatening danger. After the vehicle stopped a message on the dashboard read Hybrid System Failure. The police tried to push our vehicle to a safe spot but the wheels wouldn't turn and the car had to be towed. Upon inspection by the mechanic it appears that there is a broken shaft in the transmission that may have caused this problem. I want to emphasize that there was NO WARNING at all and we did not have a chance to move to safety.
