Toyota prius anti-lock braking issue has happened 3 times in our 2010 prius as described in media reports. It happens on slippery surfaces when the anti-lock brakes kick in, there is a split second of hesitation before they do. It causes a pretty good adrenalin rush for the driver.
2010 Toyota Prius brakes complaints

When driving on wet surfaces, my 2010 toyota prius hybrid will occasionally skid when the brakes are applied. This seems to happen at speeds under 25mph and only on wet surfaces. The first incident occurred when I was approaching a stop sign at a low speed. When I applied the brakes, the car began to slow down when it suddenly accelerated without cause. The acceleration only lasted for a second or two before the brakes started working again. I had my foot on the brake pedal the entire time and applied even pressure. This issue also occurs often when pulling into the underground parking garage of my condominium building. When the ramp is wet, this problem will often occur. To avoid this occurrence when pulling into the garage, I must proceed at a cautious pace, 5-7 MPH. This is very disconcerting because I must make a right-hand turn with three feet from the bottom of the ramp to avoid hitting the wall of the garage. The last occurrence was on january 29th at 7pm. The roads were wet. As I approached a stop light to make a left-hand turn, I applied the brakes as I normally would in such conditions. The after the initial deceleration, the brakes felt like they had slipped and I began to accelerate (as described before). I had to turn into the adjacent lane to avoid hitting the car in front of me before the brakes were fully applied. I all, this problem has occurred three times while driving on wet roads, and 8+ times when driving down the wet ramp to my underground garage. I have contacted the toyota dealership where I purchased my vehicle to make them aware of this problem and was directed to file a report to the federal safety agency. I also called the toyota customer service line and was unable to read a representative.
Tl*the contact owns a 2010 toyota prius. Whenever he engaged the brake pedal while driving various speeds ranging from 5 MPH or higher over a pothole, a bump in the road, ice or any change in the road surface the vehicle momentarily accelerated before the brakes would engage. He also stated that he heard a rattling noise within the engine compartment after the vehicle was started. The dealer was contacted and a diagnostic test was performed but produced no codes. The failure could not be duplicated and the vehicle was released to the owner. No repairs were made to the vehicle. There were no recalls. The failure mileage was 2,000 and the current was 8,000.
Momentary loss of braking on a 2010 prius model iv. Vehicle was purchased on the 30th of september 2010 and currently has 3460 miles. During the first week of operation the brakes did not seem to work correctly. We thought this might be do to the fact that the car was new and the brakes need to be used as a brake in period. We notified the dealership during the second week of operation. They indicated that this was the first concern they have received. They stated that when we bring it in for the first 5000 mile service they would check the brakes. Since the momentary loss of braking did not happen that often and only on bumpy roads or over speed bumps we were not too concerned.I did call the dealership again on 2/4/2010 and the service department stated they had not received any information on correcting the problem. What was interesting is that a person in the service department who owns a 2006 prius stated that the problem has been around for years but is much more noticeable in the 2010 model.. Toyota has assigned a case number to our complaint ( 1002108541 ). No accident to date but driving the vehicle should not include worrying whether or not the brakes will stop in time.
Brake failure while going over speed bumps. Sometimes on flat surfaces.
At 15 MPH and braking, brakes disengage for less than one second after hitting a road imperfection (an old metal and rubber sensor placed about 10 or 15 feet from crosswalk) that is perpendicular to driving direction. At 35 MPH, brakes disengage when braking and crossing a bridge/overpass connector plate.
Antilock brakes don't seem to work effectively on my 2010 prius, brought june 2009. I've been driving for 48 yrs in upstate new york; an experienced driver in the snow/ice roads. This 2010 prius is dangerous to drive on snow/ice roads. I thought maybe the tires were lousy or that I'm not accustomed to antilock brakes. But now that I'm hearing about this very problem with other 2010 prius, I'm convinced that the problem is with the car's antilock brakes. If there's any snow on the road, I know that I need alot of room to complete a stop and this is not going fast at all. I've had two near crashes so far and at very low speeds.
I have a 2010 toyota prius. The la times reported 124 reports of brakes failing, I wish to add my experiences. Twice, while I was braking, I experienced a sudden surge, a loss of braking - an increase of power. I was able to stop the car with an automatic slamming on the brakes. No accident, no injury occurred but I now refuse to drive the car. The "what if" factor is too high. I couldn't live with knowledge of possible harm to someone caused by my driving my prius! Toyota had better set this straight - I'm shocked they haven't recalled the car. I'm perplexed your agency hasn't insisted!!
Tl*the contact owns a 2010 toyota prius. While driving approximately 25 MPH over rough, bumpy surface or a pothole and trying to depress the brake pedal, the vehicle seemed to seize and glided instead of slowing down. The failure occurred on one occasion. He called the dealer and was told that there was nothing they could do about the failure. He had not spoken with the manufacturer to-date. The vehicle had not been repaired at the time of the complaint. The current mileage was approximately 150. The failure mileage was approximately 100.
I have 2010 prius. Lost control of the car a few seconds a few times especially in uneven down roads and slow or slippery roads. It jumps (move forward) a few feet, before it stops, even I apply the brake. I felt that brakes didn't work during the period.
My 2010 toyota prius slips when the brakes are applied over manholes, potholes, and uneven surfaces (differences in pavement, etc), at which time I have no control over the vehicle. This occurs several times a week, and at low speeds - since I'm applying the brakes, the speeds have been 30 MPH or less. I took the car in for a test drive 2/4/10, however, no potholes were available during the test drive, and the diagnostic check via computer indicated no error messages have occurred within the system. I was told there were no problems, and that the brakes are working correctly.
We own a 2010 toyota prius which we purchased in june of 2009. On six different occasions we have experienced braking problems. One incident was on ice and when the brake pedal was pressed the response was as if there were no brakes at all and the vehicle slid freely for a brief moment. The other five incidents involved braking on a rough surface when approaching a stop sign (3 different locations). In these cases, when the brake was pressed the car did not begin to stop immediately. In fact I got the feeling that the car had been "hit from the rear" and I jerked back into my seat a little and felt that the car floated ahead before it began to stop. This all happened very quickly. I tried to replicate the situation and was successful once. In all but one of my experiences with this dilemma, the road was on a slight downward slope approaching the stop signs. There seems to be a certain speed that is needed for it to happen. Toyota examined the brakes and said they were ok. Obviously, they are not.
The brakes on my 2010 toyota prius momentarily quit working while driving over rough surfaces such as potholes, railroad tracks or very uneven pavement. This causes the vehicle to surge forward unexpectedly under braking.
I own a prius 2010 model. I've had the car since august 2009. When pushing the brake pedal while the car os going over a patch of snow/ice, the brakes engaged after about 2-3 second. Luckily, in the few incident that this situation has happened, there was not obstacles in front of the car.
The brake lights on my 2010 toyota prius do not illuminate under light braking. There is a very discernible "gap" after depressing the brake pedal before the brake lights illuminate. Under light braking, the brake lights will not warn the driver of the car behind me that I am actually braking. This results in people tailgating me, and sometimes sounding their horn signal at me, while I am slowing down. Once the pedal is depressed far enough -- under moderate to severe braking -- the brake lights will eventually illuminate. This has been confirmed by several co-workers and friends who also own this model of prius. All of our cars have the same issue with the brake light switch.
Tl*the contact owns a 2010 toyota prius. While driving approximately 20 MPH over a rough surface she noticed that the brakes would momentarily disengage. The vehicle has not been diagnosed by the dealer. There were no prior warnings. The current and failure mileages were 2500.
1. Low driving speeds (<30 MPH), moving down hill, decelerating as approaching a stop sign. 2. When the front wheel strikes pot hole, the braking action stops/decreases, the car moves forward more quickly. In the current case, there are a series of three pot holes, so hitting each pot hole increases the forward motion despite having break pedal depressed. Consequence, is immediate difficulty to come to a stop at a stop sign. 3. No current correction has been attempted.
Prius 2010 owner. I was braking to enter a parking lot from the road. As I entered the lot, the car went over a bump in the pavement and the brakes failed for a very short instance. It didn't put me in danger but it was an immediate scare. (this happened just a few days before the media reports of this issue came out, so I related with the repots when they came out.)
I have noticed a braking problem with my 2010 toyota prius. I was slowing down because of a cow in the road and as I was slowing I hit a small bump and suddenly my brakes completely stopped working for about a second and it almost felt like the car was accelerating. I thought I was going to run into the cow and then the brakes grabbed again and I continued to slow down. It was not a good feeling. I also experienced a similar issue when I hit some ice on the road. When I hit the ice there was a brief second where the brakes seemed to be doing absolutely nothing at all. I could not feel the normal ABS feel or anything.
Tl*the contact owns 2010 toyota prius. While driving approximately 20 MPH on an uneven raised roadway surface; proceeding to make a left turn. Pressure was applied to the brake pedal, followed by an unintended acceleration. The vehicle resumed to normal operation after applying pressure to the brake pedal. The failure occurred whenever encountering an uneven road surface. The vehicle has not been inspected for the malfunction. The failure mileage was 400.
The cruise control on my 2010 toyota prius does not always cancel while braking. This has resulted in unintended acceleration after braking while the cruise control has been set. A driver expects that the cruise control will automatically cancel while applying the brakes but this does not happen under light braking. This is even more pronounced while driving up a steep hill. On january 11th, 2010, I was in a situation where I actually applied the brakes to reduce my speed while traveling up a steep hill and felt the car "fighting" against me to maintain a steady speed. After I had slowed my prius to match the speed of the car in front of me, the cruise control unexpectedly caused the car to accelerate again, placing me at a less than safe distance to the car in front of me as we crested the hill.
2010 prius brakes grab abruptly coming to a complete stop going through an intersection at about 20 MPH. I was almost rear-ended and SUV behind me had to pull aside to keep from hitting me. Also, when backing the brakes will grab repeatedly making vehicle jerk - and makes driver look like we cannot drive. See 'prius chat' site for many other like incidents by other drivers and speculative solutions. This also happens when pulling forward from parking and hit brakes in order to make a 3-point turn (example) etc. This happened the very first time I got into the car with the salesman sitting beside me, and he remarked what good brakes they were. I thought it was just an annoying trait of the car (being a hybrid) until the intersection incident last week - and the new brake news on the prius. This needs to be addressed as part of the defect before a pile-up collision is caused. It almost seems as if there is no 'power' to the brakes in a 'gliding' type mode.
My 2010 prius has had 4 instances when brakes didn't work. All involved slightly wet surfaces on a sem- potholed road in houston tx. I am taking car into fred haas toyota ,, but I am not sure anyone knows how to fix it yet. After trying to brake, there is a lurch forward before it comes to a stop. I do not feel safe in vehicle. Fortunately, I was going less than 40 MPH when it happened, and have not had an accident.
Tl*the contact owns a 2010 toyota prius with electronic stability and anti-lock braking system. While braking at various speeds and driving over a pothole, a bump or any change in the road surface, the vehicle would momentarily accelerate before the brakes would engage. The dealer stated that was normal for the braking system for his year, make and model vehicle. There were no recalls. The failure mileage was 5,000 and the current mileage was 19,000.
1. I bought my 2010 prius new from a toyota dealer in early december of 2009. 2. When I am applying the brakes to slow down, if I hit a pothole, bump, or speed bump the brakes will stop working and the car will lurch forward. I have experienced this brake failure at least 20 times, with varying severity. It can happen any time I am trying to slow down and hit a bump or pothole (e.g.. Trying to slow down because the car in front of me is stopping, or because I am approaching a stop sign or red light, or because I am turning or going into a curve). So far, this brake failure has not caused an accident but it has caused me to come very close to hitting the car in front of me on one occasion. I have come to no longer feel safe driving my prius because I cannot trust the brakes when there are bumps or potholes in the road. 3. I brought my prius to the service center of the dealership where I purchased the car. I brought the car in on 2/4/2010. That evening when I spoke to the mechanic, he told me that the brakes are normal and that he did not do anything to fix my car and that I could pick my car up. I then spoke with the manager and told him that I did not feel safe driving the car until they fixed the braking problem. My car is still at the dealership and has not been fixed because they are refusing to acknowledge that the brakes are not functioning safely.
When applying the brakes before going over a pothole I noticed that my 2010 prius appeared to speed up for a split second rather than slow down. This happened when I went over the pothole. I also noted the same sensation when braking behind cars at a stop light. If I hit a bump the car seems to slightly accelerate rather than decelerate. Additionally when driving slowly down a icy hill and applying the brakes, there was a delay in any braking. When applying the brakes harder the car did decelerate eventually. This has happened a number of times, but is hard to replicate on demand.
I purchased a 2010 prius in july 2009. Whenever I go over a bumpy road or hit a pothole while braking the car will lurch forward. I brought it to walser toyota in bloomington, mn for this problem. They said my brakes work fine. I'm still having the problem. In fact...I have it so often we have nicknamed it "prius braking." so each time it happens we say "prius braking." we know to not follow closely to anyone at a stop sign or stop light in fear of rear-ending them when the "prius braking" happens.
I own a 2010 toyota prius. I have had multiple times when I have hit a bump and was applying the brakes and the car seems to skip or float. On feb 4, 2010 I was approaching a stop sign and was braking. Just before the stop sign I hit a bump and the car slid through the stop sign and into the intersection.
When driving, and going over a rough spot in the road (pot hole, crack, etc.) the car feels like it is lurching forward momentarily, as if the brakes released. This happens every time the car goes over a rough patch in the road.
Tl*the contact owns a 2010 toyota prius. The contact stated that the brakes were momentarily unresponsive at low speeds when driving approximately 10 MPH over a pothole. She stated that the failure occurred 50% of the time she drove over a pothole or bumpy surface. She called the dealer and was told that the ABS was the cause and it was normal. She called the manufacturer and was unable to speak with a representative. The vehicle has not been repaired to-date. The vehicle identification number was not available at the time of the complaint. The current mileage was approximately 4,000. The failure mileage was approximately 500.
