Was going 50 miles an hour and all my abs and break lights went on. I was lucky I was on a straight away with plenty of space between the me and the car in front of me. What kills me is my children were in the car. I was able to stop eventually and waited hours for a tow truck and ride. I received no information about the warranty extension that Toyota supposedly got out to all those who purchased vehicles with this malfunction.
