“I have a 2009 toyota Scion TC which I am very afraid to drive but it is not on the recall list but I am having major problems with the brakes(ABS tracking system). I have had 3 very close calls as a result of my brakes locking up(going slow) and unable to stop, even after I take my foot off the brake they remain locked. One incident I almost went right into a busy 4 lane highway. It has happened on dry roads and wet roads are a lot worse, I have to start stopping a lot sooner than one should. I am very stressed when having to drive my vehicle anymore. …”

On feb 15th it has happened on the highway. It accelerated from 65 to 73-75mph while I was pushing brake repeatedly! I took the car to local temecula toyota dealer and I was turned back as they were not able to duplicate this issue and this car is not on the recall list, even thou it is build with identical accelerating and braking parts with corolla that is on the recall! …”
