When I am coming to a stop or need to put on my brakes my car will accelerate at a jump ahead pace As if to take off instead of slowing down and stopping. Regardless whether I’m turning a corner or I’m continuing straight when I have to Put on the brakes it speeds up instead.

I went to park in a parallel space when all of a sudden my ABS, (!), VSC light come on with the loss of brake power and a loud beeping noise. With this sudden loss of brakes in the middle of driving, I could have harmed myself and others in any cars around me because I also lost steering capability. This is a problem that there was an extended warranty for, but there should be a recall. My car is a 2009 and was only covered before the pandemic and now it is 2021 and I have no recourse, but to try and fork over $3500.00 for which I don't have. I am a second owner and this is a very common problem amongst Prius owners. I didn't have any other symptoms that I could point out prior to this situation. I have had my hybrid battery, engine, ecu and most recently a stolen catalytic converter replaced. This ABS actuator problem needs to be addressed for another 5 years with a free repair. I would hate to have hit some other car and had my car smash into a wall, another car, pedestrian, pole or any other object based on it's ability not to stop.

My prius now has all those dash lights on: !, ABS, vcs. I was driving yesterday, on a city street and the lights came on, and the brakes suddenly did not work-hard to push. For months, when I would drive over rough terrain, I had the loss of braking, accelerating, and the slick road icon would illuminate. The is exactly the same ABS module problem affecting 2010 prius, ands needs to be recalled and repairs covered.if I didn't stay so far behind other vehicles, I would have rear-ended someone.

Driver went to park and the brakes did not respond! In fact the vehicle went from 2-5mph to approx 30+ & kept picking up speed and went into storefront. Driver was able to wrestle vehicle into reverse and it went equally fast back into a parked car where it finally came to a stop. Hugely frightening and potentially lethal.

A year ago, upon taking off from a stop my car began to stall. I drive two blocks it continues to putt along and stall, then after less than a mile it starts to run as normal. I take my car in to be told it is out of gas, which it did not indicate low fuel, it had over a quarter of a tank. I insist they continue to check my car over days of them driving it, after a week they experience something similar and replace my junction box. Since then I've replace the water pump, taken my car in for a steering recall. Also, there are instances where my car upon take off stalls, but nothing severe, just something you feel when accelerating. Recently, 6/5/14, I experienced the same issue, but this time I immediately put gas into my car even though my indicator panel shows I have fuel. Only this time I start my car and the air conditioner is not working and it continues to stall, after turning my car on and off several times and driving a few blocks the AC cuts on and my car begins to run fine. I have been told by toyota that bc there is no indicator light and it's running fine there is nothing they can do. There was a recent recall in february of 2014 with similar issues I am experiencing but my car was not apart of the recall. Not sure what else I can do. Numerous toyota dealerships have been of no help and I fear that my safety is at risk.

Driver intentionally accelerated to avoid collision, then prius unintentionally accelerated after impact with the other vehicle, crossing the median and crossing the opposite direction street lanes then up on to the sidewalk and hit the concrete bridge rail and finally stopped. Have contacted toyota, they want up to a month to pull the crash data from the car. I asked if they could pull the data in a week, they said up to 30 days the car will have to sit at the dealership. A month is unreasonable to go without a car. They refused to send the investigator to pull the data at the body shop, said it must be done at the dealership. I gave them the name & address of the body shop.
