Driving speed less than 25mph on familiar surface street with need to stop for a car about 75 feet (estimate) in front; should have been an easy stop; applied brakes but car accelerated (I think only electric motor); further brake pressure did not stop the car, continued to accelerate (estimate 30 MPH); fender bender crash of driver side front fender into passenger rear fender and side bumper. Very familiar with car (19 years driving it) and very familiar street near my home; confusion was not a factor; no airbags on either car activated; I was able to stop when I was beyond the struck vehicle. I plan on not driving car further and have asked toyota dealer to take it back for junk without a definite reply so far

I have always had problems with the brakes on the prius, but the dealer keeps telling me there is nothing wrong with it. Yet you first hit the brakes on they are ok, but if you have to hit them hard - no brakes...yet the dealer can't find anything wrong with it. "the computer doesn't show anything wrong" I guess I will have to kill someone before I can get them to listen and fix the problem. The last 12 years have been a nightmare......why can't we get them to recall this? I seen so many people you complain about the same thing yet nothing is done?

While decelerating and driving over speed bump/raised cross walk, brakes feel like they release and the car surges forward. Has happened on a regular basis when similar conditions exist (pot holes, or anything that might cause loss of traction on 1 wheel). Dealer insists that this is "normal" for anit-lock brakes. Really just a matter of time before it results in rear-ending someone due to unexpected surge.

Applied brakes while car was moving slowly, less than 10 MPH, and heard loud grinding sound coming from left front as car stopped. Shifted to reverse and car barely moved, about 1 foot, which was accompanied by the loud grinding sound, then stopped. Turned car off and could find nothing interfering with the wheels but did find pieces of brake pad on the ground along the path the left front wheel had followed. The left front wheel appeared as if the calipers were holding whatever remained of the brake pad and/or backing tight against the rotor. Brake function had been normal for prior 7 11/12 years, ie, since I purchased it as a new car. There was a bothersome grinding, sometimes rattling or squealing noise from the left front wheel since the first year of ownership and I was repeatedly told by the dealer that nothing was wrong. Brake rust had gradually accumulated on the left front aluminum wheel but not on any others and the dealer blamed that on winter salt. It was towed to a different dealer and the front brake pads were replaced along with the front rotors being resurfaced. Despite my request, the brake pad from the other side was not kept nor was its thickness recorded. Nothing I told the service manager was relayed to whoever worked on the car and that person only recorded that the tow truck driver said the left front wheel was frozen fast. The car, 2002 toyota prius, had 43561 miles on it when this occurred and should not have had significant brake pad wear given the hybrid braking system and braking gear as well as my driving style. After the above repair was done, I learned that there was a recommendation that the left front rotor be replaced. I will have this done by a private mechanic so that the part will not be discarded.

2002 toyota prius accident *gr the consumer stated she was leaving a meeting when she attempted to release her emergency brake. She was parked on an incline and has parked there once a month for over a year. Before she knew what was happening, the vehicle started to roll backwards at such high speed that she was unable to control it by braking. Therefore, she side swiped another vehicle and caused over $10,500 worth of damage to both cars.

Since I purchased my toyota prius in late 2001, it has intermittently surged when the brake is pressed. While I do not have the high speed surges that other drivers have reported, periodically when I am at low speeds and press the brake to stop, the car will slow to a stop, then lurch forward, requiring me to press the brake harder to maintain control. I reported this to toyota in 2001 and 2002, but I was told that this was normal for a hybrid, which was fairly new technology at the time. I am concerned that in the future I may have a higher speed surge. So far my surges have been low speed, and I have been able to control them by pressing the brake harder.

2002 toyota prius braking problem*cw the consumer stated he didn't see the issue as a braking problem; rather a control conflict. Whenever the problem occurred, the vehicle was moving down a slight grade on a road surface having its share of paving patches, frost heaves, etc. The slight downgrade causes the vehicles speed to increase, or perhaps an intersection appeared ahead and for whatever reason the brakes were gently applied in order to slow the vehicle down. When the problem occurred, the symptom was a brief interval and the vehicle seemed to accelerate and then normal braking resumed and the vehicle slowed down. Just prior to the brake activation, the vehicle is in regeneration mode, in which the electric propulsion motors are acting as generators, where energy motion is being extracted and converted to electrical energy to be stored in the vehicles battery. Whenever the brake pedal is activated, the first thing that happens is that the motor now become generators are forced by the control system to convert significant energy of motion into electrical energy. The consumer believed that the normal braking system shuts down. The consumer believed the problem was with the ABS.
