At least 4 times while braking as I turn onto another road in my 2010 prius, the car seemingly jerks forward/accelerates for a split second. It is very jarring and frightening and there is clearly something wrong.

I purchased my 2010 prius on august 4th, 2009 and almost immediately noticed issues with the brakes. I distinctly remember driving in the car on this date with my wife as we were on our way back from her ultrasound. I just got off the highway and there was a red light ahead with several cars stopped at it. I applied the brakes slowly and steadily, as I normally do, braking with plenty of time to stop. As I approached the last car at the stop light I encountered a pot hole and the brakes disengaged. I could feel the car was no longer decelerating. I had to slam on the brakes and barely avoided slamming in to the car ahead of me, stopping with literally an inch between our bumpers. Since that date I have encountered this exact same scenario several times a month and have come close to an accident 2 to 3 times.
When driving my prius, I have noticed the feeling of being thrown forward for a split second after I have applied the brakes when on an uneven surface, ie a grate in the road. This occurs nearly everytime I round a corner by my apartment in which I am forced to brake as I go across a metal plate in the road.
I own a 2010 prius and purchased in 5/2009. I simply want to confirm that the brakes seem disengaged when going over bumps and stutter bumps, and this is short lived. For me, this was not enough of an issue to initially complain. However, I could see that if there was a series of stutter bumps, I might lose braking altogether.
Brake was not working when applied trying to slow down on a snow covered frozen road at about 25mph. It's not for a stop or sudden braking.
I own a 2010 toyota prius. When I apply the brakes, the car jerks forward before stopping. I am very concerned about the software problem in the ABS system and want the federal safety agency to demand that toyota fix the 2010 prius brakes. The problem with the jerking brakes happens frequently, and has happened at least 40 times over the past 4 months.
Tl*the contact owns a 2010 toyota prius. The contact was driving approximately 35 MPH on an uneven road surface approaching a traffic signal when the vehicle lunged forward immediately after the brake pedal was engaged. The driver had to apply excessive force to the brake pedal to stop the vehicle. The failure occurred whenever encountering an uneven road surface and potholes. The failures occurred on three separate occasions. The vehicle will be taken to an authorized dealer for inspection. The failure mileage was 1,800.
My 2010 prius loses braking for a split second when going over a pot hole. I've noticed this a couple of times.
01/13/2010 - I went to the service dept at toyota of wallingford to complain about the loss of brakes in a new 2010 toyota prius while driving over uneven ground. I had owned the car one month with 1500 miles on the odometer. The loss of control of the car is terrifying because the car seems to accelerate forward. The service attendant was aware of the issue and described the situation. He took the car on a test drive. He assured me it was not a safety issue.
I have a 2010 prius and would like to log a complaint that I too am experiencing the lag effect on the braking system. I read today that it could be a computer software problem. Please log this complaint so the real magnitude of this problem is tallied.
Sometimes when our 2010 prius hits a pothole, ice chunk or other bumpy road conditions we will very temporarily lose braking power. It seems to occur as the traction control or anti-lock kicks in. This has not been a one time incident, but also does not occur every time.
When I go over a bump or hit a significant pothole, the anti-lock braking system on my 2010 toyota prius seems to freeze up. I am unable to use the brakes properly and it feels like I do not have control of my car for a couple of seconds. Fortunately, I have not had an accident as a result but I am very concerned about this.
On five separate occasions, when applying the brake to stop at an intersection the car would initially begin to slow down and then, while the brake is still being applied feel like it skipped or accelerated for another 10-15 feet before stopping. The term scary could be applied to the sudden feeling of having the car accelerate when the brakes are being applied.
While braking on a downhill road and approaching a signal light, I hit a pothole and the momentarily lost braking power and the vehicle lurched forward. I continued to apply the brakes and they engaged again. Fortunately, I was decelerating and there were no other vehicles in front of me. I concerned that this could occur again with other consequences.
Since buying a 2010 prius in june, I have experienced three "surging" events while braking as I decended hills. Two involved situations involving hitting road depressions, which almost caused me to go through traffic lights, one involved a road covered with 1-2 inches of snow, which almost propelled me into oncoming traffic at a stop sign. All situations occurred as I was descending hills and slowing speed by braking. The first incident occurred in the summer, the last yesterday. I reported this to my dealer, who had no information on it from toyota, but advised me to file a complaint with toyota, which I did, case #1002106542.
When my 2010 prius goes over a pothole it surges and brakes aren't responsive enough to prevent hitting the car in front of me. So far I haven't hit any body or another vehicle.
This complaint is regarding my 2010 toyota prius which I purchased in august of 2009. Before my first oil change was due I had noticed the vehicle's tendency to not respond instantly to my stepping on the brake, and then lurch forward when the brakes did engage. My brakes also squeal even when the weather is dry. I reported this to the dealer when I took it in for tire rotation and oil change. Of course they told me the momentary pause of the brakes "was normal" and they did not hear the brakes squeal. Well my vehicle is still doing both of these things and it seems I am not the only one with a concern regarding the brakes. Please add my vehicle to the list of owners who are worried about these brakes. I have been driving for 40 years, every make and model, including tractors on the farm and I know there is a problem no matter what that dealership or toyota says.
2010 prius: when applying braking pressure on slippery pavement there is a noticeable lag before braking action occurs. This can also occur on gravel roads on washboard surfaces.
Purchase 2010 prius in nov 2009. On smooth highway ( ny lie ) traveling 70mph to pass a car. Gently applied brake to slow down but the prius lurched forward for 2-3 seconds ( 200 - 300 feet ). Almost hit car in front of me.
Slowing down while approaching a left turn lane, hit a pothole and lost braking power for about 0.5s.
As I was applying my brake my car went over a bump, most likely a man hole cover, for a split second I felt like the brakes stopped working, then it went back to normal.
Incident 1: weather condition - cold and dry. Road condition - bumpy, washboard just before a stop sign pressed on brake pedal, car slowed until washboard section of road came up, then brake seemed to disappear briefly and then car stopped. Very frightening. If there was someone in front of me I would have hit them. No injuries, no crash. Incident 2 weather condition: snow, snow falling, 1" on roadway. Location: parking lot. Came around corner very slowly due to weather conditions. Abs came on early when applying brakes and the brakes appeared not to work for a brief time and then they worked but stop was much longer than it should have been. I almost hit a wall.
2010 toyota prius while braking, if the car drive over a bump, the car accelerates. To stop the car, the brakes must be pressed to the floor board to stop and avoid an accident. The car has had this problem since purchased 8/2009.
I purchased a 2010 prius in august 2009. It shows no evidence of an anti-lock braking system. I reported this to the taylor toyota of alexandria in october who told me that they had not heard of the problem and they did nothing. Additionally, the avid factory tires on the car are not effective on wet pavement; they skid. Again, I reported this to the dealer and again they told me they had not heard of a problem but referred me to their parts department to buy new tires. Finally, when I engage cruise control, the car surges forward in speed until I depress the brake. I stopped using the cruise control.
Tl*the contact owns a 2010 toyota prius. The contact stated that whenever she attempts to stop on an uneven road, the brakes fail to stop the vehicle. Whenever the failure occurred the speed varies. The vehicle also briefly lunged forward and accelerated. The brakes squeak continuously when the vehicle is driven. The vehicle was taken to the dealer who confirmed that the vehicle was functioning normally since it has an electrical engine combined with a gasoline engine. The failure mileage was 18,000.
When carefully braking my 2010 toyota prius at low speeds (40 MPH and lower), a small dip or bump in the road will cause the car to release the brakes and the effect is a sudden acceleration or release of the braking system which lasts approximately 1 second. This failure in the vehicle is seemingly unrelated to a mechanical issue and feels more like an electrical issue, since there is no stiff pedal or obstruction near the pedal. The failure occurs on a semi-regular basis. I took the car into the toyota dealership where I bought my vehicle, suburban toyota located in troy, michigan, and reported the problem, approximately 4 months from the time I bought the car (june 2009). The mechanics kept the vehicle over night. The dealer then reported that they did experience the problem when testing the vehicle and said it was related to the anti-lock braking system and that the car was designed to move around an object rather than heavy braking. They did nothing to fix the car. The problem persists and I have heard similar complaints of unintended acceleration, both when braking and coasting. I am concerned I will at some point hit a car that is too close in front of me.
Toyota prius accelerates after hitting potholes. Cannot slow vehicle as brakes don't work immediately. This problems is random and does not occur on a regular basis.
Tl* the contact owns a 2010 toyota prius. The contact stated as he was stopping his vehicle, he hit a bump in the road while depressing the brake the vehicle lurched forward and accelerated. The vehicle was taken to the dealer and contact was told this was normal and it is the electrical engine switching to the gas engine. The contact stated that this is a continuous problem while stopping the vehicle. The failure mileage was 8,800.
2010 toyota prius accelerates for a second when I hit the brakes when I am passing over potholes or ice. It has happened wellover 10 times.
I am experiencing a loss of braking power, during slower speed stops or attempts to slow down. The problem occurs at generally less than 20 MPH. I apply the brakes and the car begins to slow, however, if I hit a bump or pothole, the car feels like it is accelerating and/or losing braking power, despite my foot remaining on the brake pedal. I am able to regain braking by further pressing the brake pedal. The acceleration/loss of braking feels like it's coming from the rear wheels of the car and at least in my experience feels like the problem only occurs when the rear wheels go over the bump or into the pothole. A similar loss of braking has not occurred when the front wheels go over bumps or potholes at lower speeds. The braking lapse causes my stopping distance to be lengthened. This loss of braking power has occurred several times since I bought my car in july 2009. I first noticed the problem in the fall of 2009 and it most recently happened this past monday (2/1/2010). The problem does not appear to occur at higher speeds, such as on a highway or main road. I was not carrying any cargo or additional weight in the vehicle during any of the incidents.
