I have been experiencing a failure of the brakes on uneven pavement or when going over man hole covers. This has happened to me three times in the first month of ownership of my 2010 Toyota Prius.

In city driving conditions, the brake pedal of my 2010 Toyota Prius fails to respond when it is depressed and the car hits a bump. The vehicle feels as if it momentarily lurches forward before it begins to slow. This is an intermittent problem that occurs when the vehicle hits an obstruction, such as a pot hole, while the brake pedal is being pressed. The most recent occurrence is detailed below.

I have had repeated occurrences of the 2010 Toyota Prius braking system abnormality recently reported in the news, since purchasing the vehicle in July 2009. I reported this at my first oil change to the dealers service center, but they did not investigate the matter.

I purchased 2010 Prius 3rd generation last August and my wife and me experienced brake problem several times. When I passed bumpy road at low speed I felt lost braking (surged forward) for a second. My wife also experienced the same problem two weeks ago when it rained in los angeles. I reported it to the dealer last October but they said there is no problem in my car. So I insisted the inspection so the dealer arranged to show my Prius to the expert from Toyota center and I had to wait it 2 months. Last month (early January) it was inspected by the expert from Toyota center at the dealership but I heard the simple answer from the dealer that the technician found no problem. Since the inspection my wife experienced the same problem again. When she was driving with our 1 year old baby passing on the pothole in the neighborhood.

I have a 2010 Toyota Prius, and I am shocked that this car was not included in the gigantic Toyota recall. Why" because the 2010 Toyota Prius exhibits brake failure and sudden acceleration while slowing down on bumpy roads. For example, if you're slowing down towards a red light, and then all of a sudden you hit a pothole, the car will suddenly accelerate and may cause a crash with the person ahead of you! this happens all the time and is extremely dangerous. Thousands of 2010 Prius drivers worldwide are also having this brake failure/sudden acceleration issue with their 2010 Prius as well! take a look at just a few of these discussions which are taking place, where people are having uncontrollable sudden acceleration with their 2010 Prius: tinyurl.com/yj359rh will NHTSA please do something about this"

I have a 2010 Prius. When I hit a pothole while stepping on the brake, the brakes let go. I have to rebrake. The car actually seems to speed up. It is very frightening. I have taken it into the dealer. They say it is the anti-lock brakes. I have had anti-lock brakes before and never have had that kind of problem.

I would like to add my report to your other complaints about 2010 Toyota Prius brakes. I purchased mine in July and since then have experienced 4 (four) instances of this problem. In each case, I was decelerating with the brakes steadily applied, and rolled over a bump or pothole in the road. At that moment, the brakes stopped working, or the braking power was severely reduced, and the car felt as if it lurched forward. Applying more pressure on the brakes when this occurs does cause the braking to resume, but there is a delay of perhaps 1/2 second. I have not had an accident so far, but if I were behind another car which was also braking when this happened, there is a high likelihood that my car would smash into the other car's rear.

When braking at low speeds, vehicle accelerates for a second before braking. This occurs when hitting a bump. I experience this almost every day on my way to work at the same location. The road is sloped slightly downhill in a residential street. I have not contacted Toyota yet.

  • 100 miles
While driving our 2010 Toyota Prius, we have noticed frequent occurrences of the car lurching while braking. This typically happens as the car hits a pothole or bump in the road while depressing the brake; the car lurches with enough force to sometimes push our bodies forward, against the safety restraints. Nothing has been done to correct the failure, but we will be calling our dealership to discuss solutions.

There have been several instances since I purchased my 2010 Prius in October 2009 that I have gone over a bump in the road and my 2010 Prius has felt like it's speeding up and I had to push hard on the brakes to feel like I had control of my car.

I own a 2010 Toyota Prius, 3rd generation. When I am braking and hit a pothole or a manhole cover, the car surges forward. I took it to the dealership today and they checked the car and said they couldn't find anything wrong with it. They also said they had no knowledge of any kind of braking or surging problems with this vehicle. Our dealer was eastern shore Toyota in daphne, al. This has happened approximately 6 different times since we bought the car in 2009. It started to occur approximately in July 2009, with the most recent episode in January 2010.

Vehicle occasionally jumps ahead during braking. Most likely to happen when stopping on a downhill grade at moderate speed (under 35 mph). Brakes engage again after brief acceleration and car so far has come safely to a stop. Date below is approximate date of first occurrence.

The brake of my car was malfunction. While breaking, the car slowed down initially. However, before the car totally stopped, it accelerated suddenly and spontaneously for several seconds. This condition happened for 4 times within 2 months. There was no ice on the road and the road was not bumping either.

My 2010 Toyota Prius accelerates over potholes and bumps in the road when I'm pressing on the brake. Even if I am braking for a few seconds, as soon as I get to the pothole, it pushes forward. This happens to me at least once a day and sometimes multiple times a day. I have only been driving the car for 5 weeks and have noticed this issue since day one.

Sporadic problems with the brakes on our 2010 Toyota Prius. We have discussed this several times on chat boards over the past five months. It happens perhaps once a month. The brakes lock when the car is in reverse. Backing out of the garage, you can just barely touch the brakes and it's as though you had slammed the full force of your foot on the brakes. Literally can cause whiplash even at the slow speed of backing out. When this problem occurs it will occur over and over as long as you are in reverse. Each time when you slightly depress the brakes, the car slams to a complete stop. What we have found is that the only way to correct it, has been to turn off the car completely and re-start the car. It may just be coincidence, but typically the brakes return to completely normal operations in reverse after the ignition has been shut off and the vehicle engine restarted. The greatest oddity is that it appears that the brakes do not respond in the same degree as the brakes are depressed. It's as though the brakes when depressed even slightly message the car to exert full braking action. It's the only car we've ever owned where the braking power seems not to be dependent on the degree with which we press the brakes. Again, this doesn't happen every time we have the car in reverse, but typically between once a month and every six weeks.
