I depressed the brake pedal and, instead of slowing down, my car surged forward for about 20 feet before brakes engaged and the car stopped --- just before the intersection (red light). I barely avoided hitting a truck in front of me (I was able to drive around). Road surface was dry,without any potholes,bumps,etc. I took the car to the toyota service center. After checking my car they informed me that the computer did not detect any malfunctions, the test drive was also uneventful,so that nothing could be done to resolve the problem. This car's braking is obviously unpredictable and it is ,without a doubt, not safe to drive.
2010 Toyota Prius brakes complaints
Page 23 of 66: complaints 641 to 670 of 1,945, newest first, as owners wrote them.
Car ABS light comes on, and at the same time vehicle loses brake assist or brake assist becomes uneven. Car has had three brake light failures - 1 with previous owner and 2 with current owner. First failure was repaired by resetting the computer, we think. With current owner, dealer has replaced the antilock sensor two times, and with the second sensor replacement toyota now has pronounced the vehicle as safe. Since the brakes failed after the first sensor replacement, we have little confidence that the problem was solved with the second sensor replacement. We are concerned about vehicle safety, especially since the car is frequently driven in heavy washington beltway traffic. Typically car runs for some time and then fails, so we do not know if and when it will happen again. Dealer and toyota have been unsupportive to our concerns.
2010 toyota prius. Consumer states when one of the front tires travels over uneven payment specifically an indentation in the road the braking action fails momentarily *tgw the consumer stated the vehicle lunged forward a few feet, before the brakes engaged again. The dealer informed the consumer the issue had to do with the ABS/trac system.
My issue is similar to others that have complained. When traveling a low speeds and I hit an unexpected bump the vehicle surges forward. This is very dangerous and one that I would hope toyota take notice and address immediately.
I first reported this to toyota prior to the initial 2010 recall, the car was less than 1 month old and I have reported it on numerous occasions via the toyota website. On the few occasions I lent the car to friends they have had the same experience. Description: when traveling at relatively slow speeds and an unexpected bump comes up and the brakes are engaged early, once going over the bump the car losses brake power for a few seconds and jolts forward. It is very disconcerting b/c in those split seconds if one is not prepared the car hurls forward and could if all odds are against me, the car could kill someone if they are walking in front of the car. I reported it to my dealer, my dealer's inspector went out on test drive with me, we were able to recreate the incident when he was driving as there are a few spots in my neighborhood that it happens every time. He put the computer on the car but it did not read there was a problem. He called the national technical office, who eventually came out, I left the car at the dealership. They recreated the problem and according to the local technician they put a camera in the wheel to film the situation. I was later told by my local technician that it was determined that there was not a problem with the car and that the situation is normal where the tire catches an uneven surface and goes into overdrive. I have had dreams that I would kill someone in this car. Noone is allowed to use this car for the same reason. I fear for my life and the life of anyone walking in front of me on a street I do not know. It happens almost every 2 weeks. It is scary! Please help! This is the first new car I bought in 25 years and I am unable to get rid of it b/c I had to pay so much for it. When I inquired what my options were, toyota said none, that there is no problem with the car.
I purchased my 2010 prius in august 2010. For the past year, I have had problems with the brake system when attempting to brake at low speeds. When braking at low speeds, such as stopping at a red light or stop sign, if the car hits a bump or a pothole, it stops braking and instead accelerates forward a bit. It is extremely frightening and I find it exceptionally dangerous. I have come extremely close to hitting the vehicles in front of me on several occasions. I now have to try to conscientiously adjust and drive very, very slowly when braking on uneven road surfaces since I have come to anticipate this problem. However, many times there is no way to avoid the car's surge of power. I believe this is a highly dangerous situation with my vehicle. A simple internet search will demonstrate that this problem exists and was not resolved with the recall in march 2010. I purchased my prius, new, five months after the problem was allegedly fixed and I have had this problem since day one. The brakes have been examined on my vehicle by a toyota dealer and they appear to be fine. I highly believe that a recall is appropriate to fix this dangerous braking issue.
When I pressed the brakes while approaching a stop I hit a bump in the road (large pot hole). The pressure on the brake released for approximately 1 second before the pressure on the brake pad re-engaged. This same scenario can happen any where from 0 to 2 times per week. In the winter when the road surface is not clear it is apparant that when the brake "disengages" the anti-lock doesn't engage because the car slides. I have slide through a red light, onto a busy street. Fortunately there have not been cars in the vacinity. I have taken the car to the dealership 3 times for this problem with no solution or recommendation.
2010 toyota prius, with 29000 miles. Pulling into a parking lot at a very slow speed, applied brakes to stop car, but it did not stop it, it started jerking forward, until it stopped when it struck a fence, injuries occured as a result, seat belt did not old back driver, and driver wipped forward and back striking steering wheel. Vehicle was towed to toyotta dealer. Still wating for toyota corp to advise of error that occured, data from cmputer has been downloaded by a private firm and delivered to toyota. 8/9/11 accident occured on 7/25/11 at 14:30.
Tl* the contact owns a 2010 toyota prius. The vehicle was included in the recall under the federal safety agency campaign id number 10v039000 (service brakes, air:antilock:control unit/module) and had the repairs performed. The contact stated that after the repairs were performed, while driving approximately 15 MPH over a uneven road surface, the brake pedal was depressed and the vehicle suddenly accelerated for a few moments. The contact also stated that the failure only occurred when driving over an uneven road surface. The vehicle was taken to an authorized dealer for diagnostics, where the technicians were unable to diagnose the failure. The vehicle was not repaired. The approximate failure mileage was 100. The VIN was not available. Had the recall done but it did not fix the problem. Toyota has been unresponsive and the dealers say there's nothing they can do. Updated 11/16/2011 *ln
Ever since I purchased my 2010 prius in november, 2009 the brakes have been a problem. When braking while driving over a bump or pothole the car looses braking ability and there is a surge of power. The dealership claims there is no problem and the recall work has not made a noticeable difference.
Brakes failed. 2010 toyota prius. 160,000 miles on vehicle. When I started the car, I had no brakes. When I put the car in gear, I then had brakes. I had brakes when I pulled up to a stop sign. As I waited for traffic I then had no brakes. When I began to move I had brakes, but then as I gained speed, the brakes went out. I managed to stop with the emergency brake. Checked the brake fluid: completely full. Dealer said the master cylinder went bad. Orginal brakes on vehicle; not even half used. Highway miles on vehicle. Very hot day. I believe it is electrical, dealer says mechanical. Had there been an accident, this incident would be looked into. As it is, no dealer will look into a car that is out of warrenty. I complained for 5 months about the brakes when I first bought the car new. Dealer told me that there is nothing wrong with the brakes. Even after the recalls, there still is problems with the brakes. Now I believe there is a problem with the master cylinder, -the electric component part of it- but toyota will only look into it when there is a serious accident.
Having problems with the braking on my 2010 toyota prius. At slow to moderate speeds while I am braking and go over a pothole the car seems to stop braking and keeps going. I then have to depress the brake harder to make the car stop. I haven't had any collisions because of this issue because I have not been following closely behind a car. But I believe if I was, I would have definitely rear-ended another vehicle.
I am experiencing the same problem as many other 2010 prius owners. The brakes fail briefly when driving over large potholes located on a grade. I have discussed the problem with a toyota dealership and was told that they are aware of the problem but until a recall/solution is issued there is nothing that they can do. They told me to brake harder when driving over potholes to compensate for the problem; the brakes, however, do not fail with every pothole. It seems like the potholes have to be a certain size, yet from the driver's seat, it's extremely difficult to judge the size of the pothole and thus if the car will lose braking power. So, slamming on the brakes for every pothole is just as dangerous as not since stopping too quickly can cause a rear-end accident. I live in a city overwhelmed with hills and potholes so this problem happens nearly every time I drive the car. It has gotten to the point where I am fearful to drive my car since I have had several close calls and know that unless this problem is fixed, it will eventually cause an accident. Briefly losing braking power may seem insignificant but until you have actually driven the car and experienced the lack of control the only comparison that I can make is driving on ice. You feel utterly helpless for the time that the car is out of your control, even if it's only a few seconds, during which time you are legally and morally accountable for what your car does or hits. There are plenty of other road hazards and safety concerns, whether or not my car is going to stop when I apply the brakes should not be one of them. I implore you, please investigate this problem and require that toyota take responsibility for fixing it and ensuring the safety of prius owners, pedestrians and other drivers. Thank you.
I was making a sharp right turn to pull into a parking space, slowing to a stop. The car suddenly and unexpectedly accelerated forward out of my control. I applied the brakes as hard as I could, with no response. As the car was racing into a tree, I shut off the engine by pushing the power button to off. The car knocked down a tree and came to a stop on top of it.
I purchased a 2010 prius. Within a 100 miles, the brake pedal randomly locked up, the brakes grabbed and brought my car to an abrupt halt. The brake pedal remained locked for about 3-5 seconds. The car would not move forward or backward until after the brake pedal unlocked itself. Initially this happened in reverse mode several times, then it was happening once a week and in forward mode as well as reverse. I took it in for repairs, most recently toyota had my car for a month. Note that during this month long investigation nothing was done to my car, it just sat there. Upon my leaving the dealership the brake pedal actually lock up! The field representative confirmed the pedal to be locked and would not release for 30 seconds or longer. He took measurements and the engineer took photos of the brake pedal as it was up in the air and not depressed as a normal pedal would be. He instructed the service manager to send me home in a loaner car and not the prius because of the brake pedal. I was so relieved that someone finally saw the brake pedal locked up and not release. After an additional week, the dealer contacted me and said that toyota determined that this condition is normal and that the vehicle is operating as designed! When I requested that the photos and measurements of the locked up brake pedal be included in my service report, the field representative refused to furnish that data. Instead, he denied he witnessed the brake pedal lock up. There were no codes, no warning lights or warning sounds, a serious safety defect in addition to the brakes locking up. The dealer informed me that toyota is aware that 1% of the prius cars have this problem and are working on a fix! I believe that the design and/or manufacturing defect have resulted in an inherently dangerous product and toyota is trying to cover it up. Please check into this, I believe many people are at risk. 1% of a million cars is a lot of drivers, passengers and others sharing the road.
Car stop on crowed warning appered on dash hybid over heating car stop. Had to restat car. By time pulled to shoulder warning light whent off. Car smelled of burning this happen on friday on sat brough car to santa monica they had no answer. As needed more info had car towed on monday left car till sat. Their diagnosis using gas and brake at same time how do you do this with one right foot? . You never drive with the left foot computoe is in error
Tl* the contact owns a 2010 toyota prius. The contact was driving approximately 5 MPH when the anti-lock brakes engaged independently and caused the vehicle to come to a sudden halt. The vehicle was inspected by the dealer who was unable to diagnose or duplicate the failure. The vehicle was not repaired. The failure mileage was approximately 100.
Tl*the contact owns a 2010 toyota prius.

Sudden loss of braking while slowing down while going over a bump. Apparently the regenerative braking fails, and the car relies on only friction braking when going over a bump. This gives the feeling of brake failure and unintended acceleration, and the only way to prevent an accident is to push hard on the brakes. This happens consistently, and has since the car was new. The toyota ABS ecu flash was performed, and made little or no difference.this is very disconcerting to say the least, and will lead to accidents. Toyota claims that this is the "normal" operation of the ABS system - in reality it has nothing to do with the loss of traction. Check out these data: http://priuschat.com/forums/gen-ii-prius-technical-discussion/93233-data-brake-loss-aka-sudden-acceleration-after-bump.html.
Tl* the contact owns a 2010 toyota prius. While the contact was driving approximately 10 MPH, the brake pedal was engaged and the vehicle began to lurch forward unexpectedly. The failure recurred whenever driving in rainy weather conditions or bumpy and icy road surfaces. The vehicle was taken to an authorized dealer and repaired under the federal safety agency campaign id number: 10v039000 (service brakes, air:antilock:control unit/module). The recall remedy failed to correct the problem and the failure persisted after the repair. The failure mileage was approximately 1,000. The VIN was unavailable.
I travel quite a bit these days and on my way home from coachella music festival, my brakes gave out. I mean to say, pushing the pedal all the way down, no resistance, no slowing, a completely limp pedal....until I repeatedly stomped on it and the car locked and skidded to a stop, feet away from the car in front of me. The brakes returned intermittently, so I took the right hand lane at 40mph and tested the brakes regularly until I got to my dealership. Scariest thing ive ever experienced. Ive had the car since august 09' and currently have 43k miles on it. I know thats a lot, and its unfortunately outside of my warranty now, but I wanted to log it here, as soon as I could. It started one day before the freeway incident, whenever I would depress the pedal, a loud high pitched squeak would come out. I didnt think much of it outside of "better get that looked at" but didnt notice any brake failure. The next morning, I turned on the car and every dashboard light came on and a fast consistant beeping went on for about 5 minutes, during which time the brake pedal had zero resistance. I sat there with a serious wtf look on my face, when out of nowhere, the dash lights went away, as did the beeping, and the car drove as normal with full regular brake pressure (besides the squeak). I received a call back from the dealership. They say it's going to be $3k for a master cylinder replacement and that toyota corporate wouldn't aid in the cost, despite my hybrid warranty still covering the hybrid ecu (the master cylinder unit includes the ecu). [xxx] (my dealership service manager) said herself that it was not my fault and that the part is not repairable, "it either works, or it does not. It must be replaced". This could have been catastrophic, had I been any closer to the car in front of me. The failure of one part (which failed through no fault of the customer) rendering the brakes nearly useless is too scary not to report here.

2010 toyota prius. Consumer states problem with the ABS system *tgw the consumer stated the first time he went to the dealer for the ABS problem, they were unable to find a defect. One month later, the consumer returned to the dealer and they reprogrammed the ABS and the brakes worked fine for about one week. Soon, the brakes began slipping again and ultimately, the consumer crashed into another vehicle. The consumer stated it seemed the brakes would fail when he applied the brake, released his foot and then braked again.
2010 prius. Brake fade during hard braking on rough surface. The brakes suddenly fade then grab hard.
Backed 2010 prius up and started to make u-turn in driveway. When pulled forward turning applied brakes and well there were none. Traveled about 15 feet and hit a brick wall. After some delay the engine now had some control as the brakes also did. Waiting for towing instructions to get the car to garage. Maximum speed was maybe 5mph.
Driving on a rain covered road and hit a rough spot in the road. Brakes did not engage at all for about 1 second. Was able to stop after that and just avoided rear ending a car at a stop sign.
2010 toyota prius--inconsistant braking and varying brake pedal pressure requirements. When braking, brake pedal travel distance varies. At times no brake action after pedal has been partially depressed requiring more brake pressure to re-engage brakes. Sometimes occurs when gas engineswitches to electric or vice versa, other times inconsistent brake action occurs with either power source. Frankly you never know how the brakes will perform. Taken to dealer-I was told no problem found. They would not keep the car for days to continue tests. This is my fourth prius and this vehicle has more problems and concerns than all the others combined.
I drive a 2010 toyota prius. In the last week I have noticed on several occasions that when braking when coming up to a traffic light, all of a sudden the pressure on the pedal decreases and the breaking power fades. Then in panic I start pumping the pedal which after a split second gets the brakes to kick in again. Luckily the car has so far then come to a halt before I hit the car in front of me. My toyota dealer has dismissed my claim saying that they checked the car and the computer shows no error code. They told me that everything is fine basically dismissing my claims of a near crash. They say there is nothing they can do and if the computer shows no error everything must be fine. The first occurrence of this was on the same day when I had to brake very hard to avoid a crash. On that occasion the brakes worked fine but driving home the same night I had the first occurrence of the above described situation resulting in a near crash.
Tl- the contact owns a 2010 toyota prius. The contact stated while attempting to brake the brake did not respond he had to increase the stopping distance he experienced the failure several times, but the failure occurred intermittently. The vehicle was taken to the dealer whom performed a diagnosed, but was unable to locate a failure code the vehicle was also test driven, but the failure could not be recreated. The manufacturer was contacted and advised to take the vehicle to local dealership. The vehicle has not been repaired. The failure and the current and the current mileage were 9,999. Li
