Brake Sensor problems of the 2010 Toyota Prius

Tl the contact owned a 2010 Toyota Prius. The contact stated that while her husband was driving at 40 mph, the vehicle in front suddenly stopped, the brake pedal was depressed however it failed to engage causing him to rear end the other vehicle. The contact mentioned that her husband was already depressing the brake pedal when they completely failed. The air bags did not deploy. The contact stated that the front seat passenger in the other vehicle was transported to the hospital by ambulance due to feeling nauseous. A police report was filed. The vehicle was towed to auto body repair facility where it was awaiting inspection by the insurance company. The contact stated that the vehicle was a possible total loss aas the radiator and engine was damaged. The vehicle had been serviced at clearwater Toyota (21799 us hwy 19 n, clearwater, FL 33765 800-667-905) for a brake issue. The dealer refused to repair the brakes under an extended warranty due to an incorrect consistent failure code. The manufacturer stated that the sensor was not alerting enough for the repairs to be covered. The failure mileage was 200,000.

I applied brake on a red light which is as usual for me and I noticed car didn't slow down and kept moving past the red light. It has happened before and the it happens on uneven and even on minor potholes. The brakes on the small bumps and minor uneven roads completely loose traction of the tires and car even faster with the brakes on when trying to stop over minor uneven roads. Mechanic said it's oversensitive anti locking brakes that cut off the brake power even when it detects minor disturbance in the sensors.

At 15 mph and braking, brakes disengage for less than one second after hitting a road imperfection (an old metal and rubber sensor placed about 10 or 15 feet from crosswalk) that is perpendicular to driving direction. At 35 mph, brakes disengage when braking and crossing a bridge/overpass connector plate.

I bought my 2010 Toyota Prius in the summer of 2009 and on the 2nd day of ownership when I was braking to make a left turn on to my street where I live the car increased in speed up when I was making my turn while braking over a bumpy surface in the road. Yhis condition only happens when the roadway has imperfections and is rough. I had told the dealer about this conditon and they said it was the sensors and it was a normal conditon which I think is dangerous because this happend when I was behind another car and came close to hitting the car in front of me.

The brakes on my 2010 Prius have a problem when going slowly over uneven, bumpy road conditions. The car seems to lurch forward during the braking sequence. It is very startling. Luckily no one has been in fornt of me, close enough to make contact. It has happened 5 times. I cannot predict when it will occur. When I first told the service dept at dealership, within 2 weeks of owning car, they siad it's just something to get used to with the braking sensor or somethiong and it isn't actually accelerating forward. I mentioned it again last week after the issues with the other cars accelerators, and the service dept said I have to replicate it with them, to address it. I called them after info was broadcast on the radio, and they said they had not heard anything. Now I hear in the news that they knew of this problem and almost exactly describe it as I experience it. I drive over this type of road daily, and am trying to avoid as much as possible.
