Traction Control Light On problems of the 2010 Toyota Prius

Tl the contact owns a 2010 Toyota Prius. The contact stated while driving 20 mph and depressing the brake pedal to attempt to stop the vehicle, the vehicle proceeded to roll forward while the pedal was still depressed. The contact stated that the traction control warning light was illuminated. The vehicle was taken to an independent mechanic where it was not diagnosed. The vehicle was not repaired. The manufacturer was informed of the failure and informed the contact that the vehicle was out of warranty. The failure mileage was approximately 209,000.

I bought a 2010 Prius in October 2009. I brought the Prius back to the dealer, stevenson Toyota, for a problem that would occur when the vehicle brake was completely depressed and the traction control light would come on. I also mentioned that when I would hit a bump or drive on ice, it did not seem that the vehicle would stop properly and that when hitting a bump, the vehicle would seem to "lurch forward". The dealer said this was a safety aspect of the vehicle and was normal operation. A few weeks later, I called the dealer again to reiterate my concerns about the braking problem and the lurching forward when hitting a bump, they again repeated that it was a safety measure new on the 2010 Prius models. Now that the recall is out, I am skeptical on the validity of their statements saying that it was a new 2010 safety feature. My wife who also drives the vehicle does not feel safe driving in the snow because of the feel of the brakes when attempting to stop. I bought the car for her but now drive it more because she does not fee safe in the vehicle.

Approximately five times while driving my 2010 Toyota Prius I have experienced problems with stopping when one of my tires either is on a manhole cover or on uneven road(one tire in a pothole). When this occurs I am usually going approximately 30 mph. I apply the brake slowly to start to slow down for a stop sign. My right front tire rolls over a manhole cover and while my foot is still on the brake my car accelerates, lunging forward. This lasts for 1-2 seconds when I have no control over the vehicle. After this 1-2 seconds my brakes stop the vehicle. The entire time my foot has been on the brake. I know that if a car was in front of me at the time, I would have rear-ended it. Every time this has occurred my traction control light goes on. I have had my car to the dealer 3 times with the same complaint. They even took the car out for a drive with me and of course we could never recreate what has happened to me. I was never told that other people were experiencing the same problems. However, in talking to people at the dealership, they said it may be the traction control because it is supposed to make your tires spin slower if you loose traction. It seems as if it does the opposite and speeds the tire up. I asked if there was any way they could check my traction control system to make sure it was working properly, but was told there is no way to check it. I am not sure if anyone has thought about the traction control system. It seems like everyone is pointing fingers to the braking system. It might be worthwhile to check into the traction control as well. It seems like a short amount of time to not be in control. But for that 1-2 seconds my heart always drops because I have no control over my vehicle.

2010 Toyota Prius brake failure. Everytime while braking if there is a bump or on even a slight bit of ice on 1 wheel only, the brakes will release completely and go back to accelerating rather than braking. It happens when I exit the highway and there is a change in surfaces from tar to concrete. It happens very often and can happen anytime. This occurs at any speed from 10mph up and I have experienced it from 10mph and as high as 55mph. The problem first occurred around 500 miles on the car and I now have over 8500 miles. This started in August around the 15th. I have a 2007 hummer h3 and I have compared the braking with the same conditions and speeds and the Prius is not responding correctly. The hummer brakes even with the changes. I have also compared on a 2006 Volvo s60. These brakes are failing and it will eventually result in a crash or a pedestrian being struck. There is no pulsing of the breaks there is only releasing for ice or for any surface other than perfect. There should be some type of repair or recall immediately. I have noticed this but thought it was only me until I saw the msnbc article. I will not let my wife drive this car since she is pregnant. It is not safe. While sitting at traffic lights the traction control light keeps turning on and blinking and will lock the brakes until the gas pedal is pressed. I have never had an anti-lock or any type of breaking issue in 15 years of driving various vehicles.
