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.
2010 Toyota Prius brakes complaints

Brakes did not work on ice. Car went forward about 15 feet with no brake action.
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.
2010 prius - braking effectiveness is lost on rough surfaces. The car gives the sensation of lurching ahead. In addition, we have experienced surging problems when using the cruise control. Rather than accelerations to the preset speed, the acceleration continues past the setting until the cruise control is canceled by tapping the brakes.
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.
When I drive on slippery or bumpy roads in my 2010 prius, I experience brake failures at low speeds. It feels as if there is a temporary surge of power and the brake system disengages -- almost as if the anti-lock brake system is improperly engaging. I have experienced this about four times, both in slippery weather and in dry weather (for instance, driving over a manhole cover). So far there have been no accidents, but this seems fortuitous. I am bringing the car into the dealer.
2010 toyota prius anti-lock brakes fail to stop skidding on minor ice.
Brakes locked up when gently pushing on pedal at low speeds in forward and reverse, anti lock brakes engage while stopped if your foot wiggles on brake pedal, brakes do not engage strong if you hit a small bump while braking causing you to not stop on target and anti lock brake symbol briefly flashes on at the same time.
My 2010 toyota prius has a recurring problem with its brakes. On multiple occasions, when I am braking and hit a pothole or other uneven surface the car lurches or slips forward and the braking action stops. This has happened to both me and my wife while driving the car. The feeling while driving the car is that the car is momentarily out-of-control and that the car will not stop in time.
Almost 100% of the time when approaching the intersection of 20th & broadway (santa monica, ca) from the east so I can turn right to head north on 20th, my 2010 toyota prius surges forward when I hit a bump/pothole in the road while braking to a stop. The surge is enough to launch the car forward into the crosswalk, so if someone were crossing the street it is possible the car may hit them. I haven't done anything to correct the failure, but I need to see the dealership about the problem.
Tl* the contact owns a 2010 toyota prius. Whenever the contact attempts to brake traveling over a rough terrain at a low speed the contact noticed that the brakes will suddenly disengage and then correct itself. The vehicle has not been diagnosed by the dealership and there were no prior warnings. The current and failure mileages were 5600.
I have a 2010 toyota prius iv and I have experienced the reported problem with the braking; namely with the brake applied and I running over a rough spot or bump in the road ( a good example is braking when going over rough railroad tracks) you feel a momentary surge or acceleration. I have noted this problem quit a few times since the car was new (car has been driven approx. 5000 miles).
I thought that it was just me but when I heard others complaining about the brakes on the new 2010 prius I confirmed what I have been experiencing. Whenever I begin to brake and either (a) hit a bump or (b) begin a turn, the car jumps or lurches as if losing traction for an overly excessive amount of time leading to a short but significant loss of control.
2010 toyota prius - odd braking behavior. On a number of occasions, when the vehicle is completely stopped and the wheels are not turning, when I press on the brake pedal, the orange "skid warning" indicator on the instrument cluster turns on. Something is wrong when I get such a warning, as the vehicle is not moving, and certainly not skidding.
1. Small patch of snow or bump 2. Loss of brakes, 2 times due to snow and 1 time due to a bump, loss of braking for about 5 feet about 20 feet before a stop sign. There is no pulsing (ABS) just a loss of braking. When it happens, I push the brakes harder and after about 5 feet at 5 MPH, I get sudden strong braking. The snow has only been on the right front tire. This is not just loss of traction because I don't hear the noise associated with that. 3. None, read other similar accounts that the deal is calling normal.
I bought a 2010 toyota prius on dec. On 12/21/2009, and have noticed on at least 4 occasions that when I brake on top of a bump in the road, the car actually lurches forward, instead of slowing down and stopping. I thought it was just me, but then I heard a story about it on npr, and now feel that this problem has been confirmed by others. I have been lucky that on the occasions when it has happened, there has not been a car in front of me, or I might have hit them from behind.
We live in chicago and own a 2010 prius. We also have experienced the acceleration (forward surge) upon braking on uneven terrain reported by other owners. No accident, but it happens often on our city streets and it is a little unnerving. The last time it happened was yesterday.
I was driving my 2010 prius and approached a stop sign at an intersection on a local road. (as I approached the intersection I was probably driving about 20 MPH or less). After I hit the brakes and had been decelerating for a very brief period, I went over a pothole or some similar protrusion. At that point, my car lurched forward, almost hitting another car. That car had been about half car length in front of me when I hit the pothole.
Tl* the contact owns a 2010 toyota prius. The consumer stated the problem has occurred a total of 4 to 5 times. The dealer was contacted and they stated that they never heard of this problem and if it occurred again to give toyota a call. There have been no repairs done to the vehicle. The failure mileage was 2000 and current mileage was 8200. Updated 3/17/10 *cn the consumer stated when he approached a stop light at the top of the ext ramp, at less than 35 MPH, he encountered a bumpy surface in the road and the brakes seemed to suddenly release and the vehicle rolled ahead. The brakes seemed to re-engage moments later, preventing the vehicle from hitting in car ahead. It was a moderate stop on dry pavement with consistent pressure on the brake pedal. Updated 05/20/10
While I was driving in city traffic and braking firmly as traffic slowed, one or both of my right-side tires passed over a manhole cover or hit a shallow pothole (this has happened several times). Braking effort completely stopped for a second or two -- the car felt as if it were surging forward, but this was probably just the change from deceleration to coasting. Braking resumed, either automatically or following increased pressure by me on the brake pedal, I'm not sure which. No collision resulted, but one easily could have if I had been following another car even a few feet closer than I was.
Driving over a bump or pothole and my brakes temporarily quit working. 2010 prius.
We have had several instances of brake malfunction in our 2010 prius. When backing out of our garage, on 3 occasions, when my foot was just resting gently over the brake, it felt as though I was stomping on the brake. It did this 4-5 times where it lurched to a stop when I wasn't applying it but just resting my foot on it as I backed up. I had an incident where I was entering a car wash and when I went over a bump into the car wash stall, the car lurched uncontrollably forward. I tried to put the car into neutral and it wouldn't stay in neutral but kept popping back into drive an lurching forward.. Also, we have 3 incidents in inclement weather where the anti-lock brakes did not work at all or did not work correctly. On a snowy day, I slid right through an intersection and the anti lock brakes did not kick in nor did the anti-lock brake indicator light come on. My husband had an incident where if felt as though the anti-lock brakes functioned only on one side of the car, propelling him straight sideways upon braking. We feel very strongly that there is a problem with this model of prius that poses a significant risk to our safety.
I own a 2010 toyota prius and have encountered the same issues with the brakes that many others have reported. When braking (which I do over a longer than usual distance and timeframe because of the car's ability to regenerate power while braking), the brake pedal drops and the car suddenly accelerates whenever the vehicle hits a bump or pothole. This has happened multiple times since I took possession of the vehicle in june 2009. No accidents or injuries have resulted, but I must be particularly cautious of road conditions when braking because this happens frequently and I am concerned about the possibility of future accidents or pedestrian incidents.
Braking power suddenly gave out momentarily. This occurred at low speed. However, I was approaching a crosswalk with a pedestrian in it. If felt like the car lurched forward. I read the article in the nyt this morning which noted this problem with the prius and this definitely fits my situation. It does not happen frequently (3 or 4 times at most), but it is obviously a safety issue. I purchased my 2010 prius new on nov. 3, 2009 from toyota of seattle. I contacted the dealer about this issue a few days ago, but have received no response.
2010 toyota prius frequently accelerates briefly when braking after hitting pothole or going over a bump. In addition, frequently at start up, the brake pressure is extremely high, and the slightest release of the brake causes the car to lurch rapidly either forward or back, depending upon whether in drive or reverse.
When braking and going over rough road or potholes, the car feels like it is accelerating. It is necessary to exert additional pressure on the brake pedal, but sometimes does not feel like this is helping.
I purchased a 2010 prius in june, 2009. I have noticed a "surge forward" if I apply the brakes while going over bumps like railroad tracks or potholes. This has happened repeatedly. I just saw a report in the media that others have had the same problem. I will report it to my dealer in madison, wisconsin.
I purchased a 2010 toyota prius on dec. 23 2009 in columbus oh, and experienced brake problem twice. When I was coming out of my street to merge to a bigger street, I used the brake trying to stop the car. Instead of coming to a stop, the car jumped forward. I had to brake it again and hard to stop it. I felt as if there was an internal energy pushing the car forward. This happened to me twice. The first time was 3 weeks ago, the second 2 weeks ago.
2010 toyota prius - braking issue on slippery service - I find the braking distance required to stop the vehicle is excessive when compared to my previous vehicle on slippery services. This has resulted in the vehicle rolling forward into intersections before coming to a stop. I live in mn where road conditions can become less than ideal. I do not believe that I am traveling at an excessive speed but I have know adjusted my driving habits to account for the extra distance required to stop.
I have been driving my 2010 prius for 4 months and everyday I drive over this road near my work that's not a total flat surface with a bump, my prius just jerks and slides forward and accelerates for a split second. This happens every single day I drive to work over this bumpy road. It worries me if a pedestrian is walking in front of me I am not sure if I can pull to a complete stop in time.
