Since purchase in october 2009, I have experienced occasional problems with the brakes on my 2010 toyota prius. Sporadically, when I apply the brakes to slow down going down a slight incline or stopping at lights or intersection, I feel a momentary lag before the brakes actually function. The lag is noticeable and similar to feeling airborne or slipping causing me to frantically push down harder on the brake pedal than usual. This has recurred perhaps 10 different times I also had one incident when the brake seemed to lock when the gear was in reverse and I was beginning to back out of a parking space. Please note the date of incident and MPH is only an estimate.

I purchased a 2010 prius (which was in stock) on january 8. After hearing about the brake delay problem, I realized that I had had a similar problem. I was traveling at medium speed when I felt the car dip, then shudder. I felt that I had lost control of the car. It felt like it was sliding (as though on ice). Now I realize that I must have put on my brakes, but the car continued to proceed. I had not noticed any problem in the road, and no reason to explain the shuddering. It was all very brief. I have an appointment to see the maintenance people at toyota grapevine, texas, on monday, february 9.
This is not the same 2010 prius brake problem being reported regarding transient brake failure. While waiting in gear at a traffic signal with foot on the brake pedal, the pedal slowly sinks all the way to the mechanical stop. However, the car does remain stopped even when the accelerator pedal is briefly tapped. The behavior is repeatable and consistent. Personally verified that there are no external hydraulic leaks. Observed the fluid surface in the brake fluid reservoir while an assistant sank the brake pedal. The surface remained undisturbed, indicating that the master hydraulic piston is not leaky. Took it to the dealer. The sales & service managers observed but reluctantly admitted the behavior, tested it on their computer and declared it acceptable. I tested a second 2010 prius on their lot and the behavior was identical. Consequences: having dealt with dealers before, we are unwilling to accept the dealer's reassurance for this seemingly unsafe behavior, and are now compelled to set the parking brake at every waiting stop.
I have experienced braking problems with my 2010 prius during the following circumstances, which I have mentioned to my husband and my coworkers when it happened. 1: on my way to work there is a stop sign where I need to make a left turn. Just before the stop sign the road is uneven. When I brake there, I feel a jerk and jump before the car stops. 2: I was on my way to work, on 01/28/2010 when it was snowing lightly, the vehicle speed might have been at the most 5-8 miles/hour. I saw the light turning yellow from 50 feet ahead and I started applying the brake. The road had little slope but the vehicle was not only skidding, but also not stopping and I was praying that it will stop before it goes into the cross road. I am the primary driver for this vehicle and I love this car. But I have experienced from the very beginning that the vehicle doesn't stop quickly when I brake, but always thought that was part of hybrid technology and may be to force the driver maintain some space from the vehicle in the front.
I have a 2010 prius and have had trouble with brakes since I bought it. Dealer has been contacted three times and letter to toyota with no response. The brakes are not right and I am afraid I will be in an accident.
Prius 2010--pause in braking while approaching stop sign. Road conditions were snowy and uneven road surface. Braking paused for several seconds, enough so that I would have collided if there had been car ahead at stop sign. Happened again about 1 week later in the exact same spot.
4 instances of failure of the brakes to stop the car 1st time in june 2009 at a stop sign - had to push brake very hard to get car to stop 2nt time in aug 2009 again approaching a stop sign brake would not engage until pushed very hard 3rd time sept 2009 same situation last incident 2.1.10 same situation. Road had some snow on it.
While applying the brakes to slow down to go around a curve that also goes downhill, my 2010 toyota prius seems to speed up for a few seconds in the midst of the turn. I can't tell if this is the braking system failing or the accelerator kicking in. It's not centrifugal force, because there is a clear surge forward. This happens pretty regularly, as this is a maneuver that I make regularly on my way home. I put in an arbitrary date below, because it has happened many times. I notice this happening at other times too, but I don't have a consistent record of when and where it happens.
I own a 2010 toyota prius and frequently (~1 x week) experience a braking problem as being reported by the media. If, while I am braking, the car goes over a bump, pot-hole, or wavy pavement, the car feels like it isn't braking, as if the wheel is off the ground or sliding on ice. It only occurs while the car is being bumped, so usually it is only lasts a matter of a few feet. I hope this helps you identify the problem and determine a course of action.
I bought a 2010 toyota prius in the end of december 2009. Since then I have experienced the momentarily brake loss when driving over the uneven surface. It only have happened 2-3 times but it makes me worry about the safety of my family and myself.
Temporary brake failure when braking over potholes or braking in a turn
My 2010 prius stops braking or accelerates when hitting a pothole or bump causing the car to stop later than anticipated. Almost hit a person in the cross walk.
1) while driving my new 2010 toyota prius straight ahead at approximately 10-15 MPH on a dry, sunny day, I hit the brakes hard to stop at a red light. The car skidded loudly enough that several bystanders looked at me. This was clearly a failure of the anti-lock braking system. I recently brought the vehicle to my toyota dealer (toyota santa cruz), which inspected the brakes and declared them to be fine. This problem has not recurred, though I have not had to apply the brakes in such a strong manner since that one incident. 2) on two separate occasions, while driving the same prius at very slow speeds (perhaps 5 MPH) shortly after starting the car, my wife gently applied the brakes; the vehicle jerked almost to a stop. In other words, a gentle application of the brake pedal LED to a very rapid, jerky, stop as if she had slammed on the brakes.
I experience a loss of brakes at least two or three times a day with my 2010 prius. This happens everytime I press on the brake and hit a bump in the road. I live in new orleans and our roads are notoriously bumpy so I loose my brakes often. This has been happening since I purchased the vehicle back in november. The dealer refused to do anthing about it, saying that it was acting how it was designed. I have never owned a vehicle that looses it brakes when the car hits a bump.
While braking, right front wheel hit a small pothole and brakes disengaged for a split second. *cn updated 9/29/11
We purchased our 2010 toyota prius in june of 2009. I have noticed that when I accidentaly hit potholes and try to apply the brakes at the same time it feels like the brakes do not hold. I do not have a set date when I first noticed this, some time in late fall on a rainy night. I thought I was just imagining this until recently when I heard others were experiencing the same thing.I love this little car, but now I am afraid to take it anywhere.how do I find out the results of your investigation?
I was driving my 2010 prius approximately 20 MPH on an icy road. Because it was icy, I started braking very early before coming to a stop sign. There was no response from the brakes at all. I blew through the stop sign out onto a 40 MPH road. I was only able to avoid a collision by steering away from cars. I applied the brakes the entire time, which was several seconds and the brakes never engaged. The next time I used the brakes, they worked. Initially I thought that the reason the car did not slow down was because it did not have any traction due to the icy conditions. But after thinking about it, I did have traction because I was able to steer quite well and suddenly change directions without any slipping at all. This did not make sense to me until I read about the braking problems. My husband has experienced the car lurching forward when applying the brakes on a slippery or uneven surface many times. He applies the brake and the car lurches forward before the brakes engage.
I have a 2010 toyota prius; purchased new on 3 jan., 2010. I now have about 4400 miles. Recently in the news I've heard loss of braking complaints. My complaint is the opposite. Sometimes when traveling very slowly backwards or very rarely slowly forward and I press lightly on the brakes they grab as tho I pressed hard for an emergency stop. This has happened about 10 times. This has yet to occur when traveling at speeds above about 5 MPH. This occurs usually when backing and usually when the car is cold. If it happens it usually happens multiple times in just one attempt to back out of a parking spot.
Occassional very brief loss of braking when going over uneven pavement, speed bumps or traffic calming devices at a slow speed. No injuries or collisions as a result. Have not contacted dealer yet but am awaiting potential recall notice.
I have a 2010 toyota prius and have experienced the braking problem. When braking with the foot off of the gas pedal, the car will lunge forward with acceleration. It will stop when I hit the brakes harder. This is happening on dry pavement. This has happened on 3 seperate occassions.
I own a 2010 toyota prius. When I approach a pothole or rough patch in the road and apply the brakes as I am driving over it, the brakes slip and the car lurches forward. This has occurred six times since I purchased the vehicle in september of 2009. I took the car to toyota of santa monica on february 5,2010. They ran a diagnostic test and concluded that nothing was faulty within the braking system. This is the same day every news organization in the world was reporting that toyota admitted there is a software problem in the ABS braking system and was repaired on 2010 prius models built from january 2010.
I stepped on break padel on my 2010 toyota prius on a bumppy uneven road but the car didn't stop properly and slipped a few feet instead.
While traveling over a speed bump and applying brakes, brakes malfunction for a period of time. While traveling to car dealership and coming to a stop to make a turn, the road was uneven, and the brakes again did not function immediately. On both occasions, no cars were directly in front of may car.
On several occasions my 2010 prius has failed to stop immediately when I have applied the brake at slow speeds. This has occurred while on ice surfaces as well as clear surfaces. There is just a fraction of a second delay before the brakes take hold. Fortunately there has not yet been an accident but if I were to have had less space between me and the car ahead, there would have been a crash.
Momentary brake loss. 2010 prius, mfg. Date 12/09. Purchase date 2/1/10. Low speed slowing down with light braking for stop light. Happened over a man hole cover (I think). When it felt like the brakes quite momentarly.
While driving on 2/5/10 in snowy conditions at about 15 MPH, I slid through a stop light in my 2010 prius. I was driving cautiously, applied my brakes early, knowing the light might change. It changed to yellow and I had no brakes and slid into the intersection as the light turned red. I have had anti-lock brakes in my last two cars and have had my ABS engage previously on my 2010 prius. During this event, no braking of any sort took place even though I had the brake pedal depressed. Fortunately, I was not hit by other cars in the intersection. I have not had the problem examined yet, but will be taking my prius to the dealer.
I own a 2010 prius. The day after the purchase, the brakes would grab when in reverse as brakes were applied. I returned to the dealer who said they could find nothing wrong and was perhars due to a little rust on the rotors and and to return in problem recurred. The grabbing and jerking continued while braking in reverse at low speed and I again returned to dealer. This time they said it could be due to interaction between the mechanical brake and the the regenerative brake but had no improvements to offer. The problem continus to date. It does not happen when going forward . However, I thought you might be interested as it may indicate a general software error ifor controlling the interaction between braking modes.
Halfway down a hill in this vermont village is a right turn that goes uphill. I have driven this is in winter weather in many different vehicles for over 40 years. On this day there was snow on the road so I was driving slowly going down the hill and was going to make the right hand turn but when I applied the brakes they reacted unlike any other car I have driven in those conditions and just seemed to cause me to slide instead of slowing down. At that point I decided not to turn and continued carefully down the hill. Fortunately there were no vehicles in front of me or I felt I might have slid into them. Later that week I called and talked to the toyota service manager where I had bought the car. He said he wasn't aware of any problem with brakes, that he had a prius, although an older model, and hadn't had any problem. He had heard from one other person with a braking complaint on the 2010 model. I asked him to inform me if he found out anything but I never heard from him. The condition was serious enough from my point of view that since I have a second car I have not used the prius in inclement weather. I would consider this, in light of recent disclosures, to be a very serious and unsafe condition to put me, me family and others on the highway at risk and would hope that a recall and resolution to this problem would be quick and forthcoming.
Brakes are unresponsive at times, it jerks during slow and steady application of brakes on rough or slick road surfaces.
Toyota prius 2010 - breaks failed to stop car on 3 separate occasions during the past month. Each occurrence was at an intersection (roads each time were plowed for snow, but still a bit slick). The car eventually stopped due to the vehicle slowing down, but still not breaking. One occurrence was at an intersection where the car did not break at a red light and I quickly turned the wheel to the right to proceed onto a side road. I have called the service department at the toyota dealership (where the car was purchased last fall), and have not received a response.
