Neither the manufacturer nor dealer was contacted. There were no recalls. The failure and current mileages were 2200.
2010 Toyota Prius brakes complaints

Car did not brake properly and slightly surged forward on many occasions when I drove over a manhole cover and speed bumps at lower speeds. In one occasion, I rear ended a car and cracked my license plate frame but since there was no further damage on any of the cars involved, we agreed to drive away.
The following describes exactly the problem: " .... Momentary loss of braking capability while traveling over an uneven road surface, pothole or bump." I've had this happen several times since I purchased my prius in nov 2009, most recently this morning on the way to work (going down hill!) on the road. I've never hit anyone or anything but the risk of that happening is there and must be addressed with a recall & repair.
Our 2010 toyota prius surges (accelerates) for a fraction of a second whenever the brakes are applied as it hits a small bump or slick spot in the road. This hasn't caused any accidents, but we drive the car primarily at low speeds (40 MPH or less) and haven't been involved in any situations (yet) that required evasive action. We are concerned that, at higher speeds, or in a case where someone pulls out in front of us and we have to apply the brakes quickly, the vehicle will not respond appropriately. I have told my toyota dealer about this problem twice, and they have no response. About what to do about the problem. All they said was that the car has not been recalled, and that I should touch base with them periodically for updates. They took my name only when I pressed them to push the information back to toyota management.
I have a 2010 prius bought in september. I have experienced the surge while braking about 4 or 5 times in 5,000 miles of driving. I didn't connect it with braking as it was a surge. I think that the roads were wet each time this happened. I stepped down hard each time and the surge disappeared after about a second or so.
2010 prius with ABS problem. On uneven surfaces (I.e. Potholes) or icy roads I have not had 3 events where the brakes were not effective. One situation was so bad and almost caused a serious accident under snow/icy conditions that I brought the car to toyota immediately. I have a service record of that in mid december 2009. The service department kept my vehicle for a couple days and did icy road testing but never fully recreated the situation. I have documentation from the service department on this despite their not acknowledging a problem. I have a lot of recollection of the details leading up to the 3 scenarios that have occurred now and can likely give good insight. Btw, from the stories I read today in the press I think toyota (and the stories) have the problem mostly described. I still have other concerns based on my experiences from the 3 events.
On my 2010 toyota prius ii (purchased 9/30/2009, I have noticed on multiple occasions that while I am braking, if I hit a pothole, bump or rough pavement of some type, the braking suddenly releases for half-a-second or a second. I am maintaining pressure on the brake pedal but with a bump, it stops braking momentarily. Because I tend to give myself a lot of room to brake, none of these incidents has LED to an accident, but it is very disconcerting.
I have experienced braking issues with a 2010 prius purchased in july '09. While braking on ice or snow when first depressing the brake pedal for light braking nothing happens, no braking. When then depressing the brake pedal more firmly braking then starts suddenly but more aggressive than desired. This problem occurs on ice or snow only but I have not driven on extreme washboard or gravel roads. I have had the experience more than once and have begun to anticipate it happening regularly on ice or snow.
Tl*the contact owns a 2010 toyota prius. While driving 30 MPH the vehicle became difficult to stop when he drove over speed bumps. The contact stated that when the vehicle surged forward it felt as if he lost braking ability. The contact has not taken the vehicle to the dealer to have the failure diagnosed. The failure has occurred since the vehicle was purchased. The contact is concerned that a crash could occur if the vehicle continues to lunge forward. The failure mileage was 4,500.
Tl*the contact owns a 2010 toyota prius. The contact stated that when driving over a rough surface while depressing the brake pedal the vehicle accelerated; however, the failure did not recur on smooth road surfaces. The failure occurred on a weekly basis. He called the dealer and was told that there was nothing they could do to repair the vehicle until the manufacturer advised them. The vehicle identification number was unavailable. The current mileage was approximately 5,000. The failure mileage was approximately 20.
When driving my 2010 prius over bumps with my brakes on, the car lunges forward as if the brakes are not working. This occurs each time I hit a bump when I have my foot on the brake pedal.
Tl*the contact owns a 2010 toyota prius. The vehicle lunged forward and accelerated while the contact was driving approximately 20 MPH and attempting to engage the brake pedal. The vehicle was diagnosed by the dealer who confirmed that it responded normally since the electrical engine switched over to the gasoline engine. The contact observed that the malfunction occurred continuously. The VIN was not available. The failure mileage was 17,000.
Pulling into a parking spot, hit a small bump, the car lurched forward while my foot was firmly on the brake.
I am the owner of a 2010 toyota prius purchased new on january 21, 2010. Car has about 400 miles on the odometer. On february 2, 2010 while attempting to stop at a stop sign, traveling at a slow rate of the speed, the brakes failed to stop the car. After several attempts to apply the brakes, they finally stopped the car narrowly missing cross traffic. The pavement was smooth and speed was less than 25mph.
2010 prius brakes appear to become inoperable during transition from electromagnetic to hydraulic braking. I've had this occur an three occasions, twice during aggressive braking (near misses). Once this occurred at low speed on a patch of so-so road during light rain. The other two times this happened at 40+MPH on very good dry road. I took my car in to my local toyota dealership yesterday to evaluate this concern and was informed that my brakes are not malfunctioning. The dealer seemed unaware of the issue and the fact that toyota had corrected this issue in the cars currently coming off of the assembly line. The dealer position seems to be that the prius brake system is advanced and does not operate like other brake systems. My position is that brake system design should not contribute to driver panic during aggressive braking.
The issue with the brakes on the 2010 prius has occurred several times on our prius, which was purchased in august of 2009. Coming downhill and going over a speed bump there is a sudden slight acceleration when we apply the brakes. Fortunately, no accident has occurred.
I own a 2010 prius purchased in july 2009. I have also (regularly) felt a surge forward when braking and hitting a bump or pothole. Based on my readings of chat boards I thought this was normal, although it is quite alarming when it happens. I'm not confident that my local toyota dealer would be entirely honest; when I was in for service during the floormat brake recall I overheard a service manager telling a customer it was nothing to worry about; it was only when people put non-manufacturer's floormats on top of the toyota ones that there was a problem (which is not my understanding). I'd like to be kept informed of the status of the investigation if at all possible. I'll put in early august as the "incident date" but it happens regularly (at least once a week?)
Tl*the contact owns a 2010 toyota prius. He stated that while depressing the brake pedal at speeds of 10-15 MPH and going over a rock or a speed hump, the brakes would loose traction momentarily. The dealer was contacted and advised that was a normal function of the ABS braking system. No repairs were made to date. There were no recalls. The failure and current mileages were under 5100.
I have had my 2010 prius for about 45 days, and on three occasions while traveling over bumpy surfaces and very firmly applying the brakes, I noticed a lack of stopping power for about half a second right after I hit a bump. They weren't tiny bumps, but they weren't craters either. The traction of my tires did not seem to be impaired. It felt like the brakes just let off for a fraction of a second.
I've experience braking problems with my 2010 prius. As others have reported I too have had at least a dozen incidents in which I am applying the brakes and there is either a bump in the road or more often a pothole. Usually this has been when I was approaching a stop sign and braking moderately. The experience is such that the brakes seem to disengage at the time in which I hit the pothole or bump and the car lurches forward for just a split second. To me it feels like going over an ice patch and the sensation is similar to hydroplaning as well. This has not caused any accident but does contribute to a feeling of lose of control and causes you to possibly stop a little later than you intended to. I have 10,000 miles on this car and have had it since august 2009. I also experience another braking issue. Sporadically when I start the car and the engine has not come one and the car is only using battery, the brakes seem to have no play in the pedal. The car starts to move and when I tap the breaks they just lock with a thud and the pedal goes all the way to the floor. I then re step on the brakes and they work properly and feel normal. This usually happens in my driveway or parking lots and my first reaction is that I hit something because the car slams to a stop.
Toyota prius 2010. Problem reported to dealer 12-18-2010. Brakes become inoperative when passing over uneven surfaces, vehicle also at this time vehicle lurches forward. This occurs frequently. Contrary to your form requirements there is no one "approximate incident date". Shifter sometimes is difficult to put into neutral, rather it will instead go from drive to reverse. If there is also a sudden acceleration problem, this could be a big problem when trying to regain control.
Brakes on 2010 prius sometimes are "jerky". The pedal feels different and I require less or more pressure to get the car to brake. Occasionally when I press the brake the car jerks to a stop instead of a slow, controlled stop. I have been driving for over 20 years & the feeling is similar to how I felt in learning to drive when I didn't know how much pressure to use on the brake pedal. Bought car in october 2009 - problem noted about 10 times since that date.
Prius 2010 "skidded" at slow speed on cold roadway twice. Just purchased the car in october.
2010 toyota prius- if I drive over a pothole or a manhole cover while braking, the brakes feel like they release.
Tl*the contact owns a 2010 toyota prius. The contact stated that when she was driving over a speed bumps and the vehicle suddenly accelerated with her foot on the brake pedal. Whenever she drove the vehicle the failure occurred. She called the dealer and was advised that there was nothing they could do to correct the failure. She has not spoken with the manufacturer to-date. The current mileage was approximately 10,000. The failure mileage was approximately 10.
1. Slowing down to make a right turn, traveling around 15 MPH 2. While traveling over a pothole or uneven road surface, brakes suddenly disengaged and car continued forward 3. Brakes reengaged after about a second later.
2010 prius iv problem with brakes when going over bumps or dips. Brakes do not work while going over bump or dip.
I purchased a 2010 toyota prius (model v) in august 2009 and have had issues with the brakes ever since then. When driving on rough or uneven pavement, if I depress the brake to slow down, the car seems to skid or almost shoot forward instead of braking. The end result is that instead of immediately stopping, the car ends up sliding for about a second before stopping, which could obviously lead to an accident given the extra distance the car is traveling instead of braking immediately. After this happened repeatedly on a street near my home in san francisco, I took the car to the toyota dealer from which I bought it on november 24, 2009 (city toyota in daly city). After evaluating the car overnight, they gave me a written report (a copy of which I'm happy to provide) and told me that it had something to do with the antilock brakes but said it was a "normal characteristic of [the] vehicle." note that while they were looking at my prius, they gave me another loaner 2010 prius (model iii) and that car had the exact same issue (also noted on their written report). After listening to the news and seeing an article this morning where toyota admitted there were braking issues with 2010 prius cars made before january 2010, I became extremely concerned about the safety of my car and potential for an accident. I also understand that there are over 100 complaints for the same issue and want to add my experience to that list to ensure that toyota does a proper recall of my 2010 prius to fix the issue. I'm also extremely annoyed that I was told by a dealer that this was a "normal" condition only to find out now that it's absolutely not normal and that there are a significant number of individuals that have experienced the same problem, some of which have caused accidents. I just want the problem corrected.
I have a 2010 prius and am also having brake problems. The brakes intermittently seems to slip for a couple seconds. It seems to happen at low speeds, on hills, and in the middle of the time I am pressing on the brake. It has happened both while continuously pressing the brake and also as I ease off the pressure on the brake. The behavior is occasional, but recurring.
Momentary loss of braking when passing over bump in road while braking for stop light. Third time I have personally witnessed this momentary loss of braking.
