  • 46,485 miles


The contact owns a 2010 Toyota Prius. While driving approximately 30 mph, the brake pedal was depressed but the vehicle failed to slow down until excessive pressure was applied. The vehicle was taken to the dealer where it was diagnosed that the brake booster nitrogen fuel leaked into the brake fluid. The brake booster pump assembly was replaced. The VIN was not included in NHTSA campaign number: 13V235000 (service brakes). The manufacturer was notified of the failure. The approximate failure mileage was 46,485. Updated 10/06/16

Design flaw....loss of brake function during braking events while going over bumps and potholes (lower speeds <30mph). I believe the root cause is the transition between regenerative braking and hydraulic brake. I always feel unsafe during braking events, and always have to be proactive and calculate the distance in front of me to accommodate the loss in stop distance. Very uncomfortable feeling!

Brakes suddenly stopped functioning while driving 55 mph on 4 lane highway. Dashboard alarms also indicated there was a brake problem. Per Toyota technician at prestige Toyota in kingston NY, gas bubbles contaminated brakes and ruined pump and actuator. According to Toyota warranty assistance representative "fred, " who spoke with local technician, there was a recall for this exact condition, but did not include my particular VIN. I was very lucky not to have been in a serious accident, and I have to wonder how many other Prius drivers are at serious risk because of similar condition.

Oncoming car stopped at traffic light while I was proceeding straight in the opposite direction. The oncoming car then made a left turn across the road in front of me. I started a turn to the right assuming that the other car would see me and stop. At the same time I hit my brakes. My car seemed very slow to decelerate. I now realize that car brakes can give much more significant stopping. At the time, because of my training as military and airline Pilot, I stayed on the brakes and did not pump them. In retrospect, pumping the brakes might have gotten them to work. The anti-skid system seemed to be ineffective. I struck the other car at its right front wheel. My airbag worked wonderfully, but my car was totaled. As no person was hurt, the police were uninterested. The accident is on file with riverside county sheriff's office as file# MV142810251. The date was 10-8-2014.

On 05/25/2016 at about 9am, while in motion at a rate of speed approx 25 mph on a street during construction (don't know if the bumpy road had anything to do with it), the change oil soon light appeared and seconds later all the lights on the dash came on with the message to check the "check hybrid system". I tried to stop the vehicle and it kept accelerating. I pressed on the breaks really hard and the traction control light kept flashing on and off like crazy but it barely had any impact. Although the vehicle slowed, it did not come to a full stop. I ended up hitting the vehicle in front of me. Thank god it was a truck and as able to stop the car from moving further or I could of ended up in the middle of an intersection. After the collision, the car would not stop although the park button was pressed and light was on. I even tried turning off the vehicle and the vehicle stayed on and in drive. I ended up in the hospital and don't know how it eventually got turned off but that was very frightening. I had my children in the car. On impact, the seat belts did not even tighten.

At 46,900 miles without any warning all the brake warning lights came on and braking effectiveness dropped off. Have to push pedal to the floor to get the car to stop the lights for traction control, anti lock brakes and the word "brake" and another light like a circle are on all the time normally there is strong braking when first touch the brake pedal but now very limited braking until push down very hard on the brake pedal. Looked at brake fluid and it is full, do not know why the brakes are not working

While driving home from work, the brakes went out on my Toyota Prius and the warning lights for ABS, traction control, and brakes all came on. I still had a small amount of brake pedal left and the emergency brake continued to work. When the Toyota dealer diagnosed the problem today, they said that it was a $3500 brake booster and that it was not covered under recall or warranty. The symptoms, the warning lights, and the results all match a previous Toyota recall (D0H) exactly, yet they will not include my car under the recall because my VIN is not part of the original recall. They're lucky I wasn't physically injured in accident caused by this. I suggested to their customer service rep that maybe my car should be included in the recall, but they did not agree.

I was driving my vehicle at about 35 mph on a two lane, hilly road. Suddenly, the ABS and warning lights started flashing, and there was a loud beeping noise. I pressed the brake pedal, and there was no response. Since I was traveling uphill, I slowed and then used my emergency brake to come to a complete stop. After the vehicle was towed to a Toyota dealer and diagnosed, I was informed that there was an internal leak in the hydraulic unit of the braking system, and that the ABS pump module and brake master cylinder needed replacement. This was a very similar issue to a recall of other 2010 Toyota Prius vehicles, but the recall does not apply to my VIN number. Toyota claims that the problem was "remedied" before my vehicle was produced even though one of my trouble codes is the same as the trouble code referred to in the recall.

The contact owns a 2010 Toyota Prius. While driving at various speeds, the brake pedal was depressed but the vehicle failed to slow down. The contact had to depress the brake pedal with extreme force in order for the vehicle to stop. The yellow and red brake system warning indicators and the ABS warning indicator illuminated. The contact also stated that the brake pedal felt like a sponge once the brake pedal was fully depressed. The vehicle was taken to a dealer where it was diagnosed that the brake booster assembly and the brake booster pump assembly failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and stated that the VIN was not included in NHTSA campaign number: 13V235000 (service brakes). The failure mileage was unknown.

This is very unsafe.

Brake booster pump assembly vehicle in motion when on highway when loss of breaking and steering took place. Vehicle lighted icons appeared on dash along with alarm sound. (ABS) (!) (brake) (ss). This unsafe condition could have been avoided if NHTSA would have forced Toyota to recall this defective part in 2013 when Toyota notified NHTSA of the defective braking system. Or Toyota mailed notice to customers as stated back in 2013, which prevention could prevent loss of life or harm. Or class action. www-ODI.NHTSA.dot.gov/acms/cs/jaxrs/download/doc/ucm442011/rcmn-13V235-0909.pdf

The issues is my brakes. When I am slowing down at an intersection, typically when the road is wet, if any of my wheels passes over a manhole, or pavement striping that is slicker than the pavement, the brakes will release. On several occasions, my car has gone through or partially through the intersection. Recently this caused me to run a red light. This has been going on since I purchased the car used. I took it to the dealer (burien auto, burien, wa) about 18 months ago with a note explaining what is happening, and the mechanic said he road tested it and there was no problem.

  • 139,500 miles
My car at 139,500 miles driving straight on a main road at 45 mph had three lights come on, red 'brake' light, yellow 'ABS' light and the yellow 'tcs' light. Earl stewart Toyota diagnosed problem as brake actuator needs to be replaced at a cost of labor/parts of 2,100$. I was able to financially afford the repair so I told them to perform the repair. Less than two days later, driving normally on a main road, the same three warnings appeared, and of course upset me greatly. Toyota this time diagnosed the problem this time as the brake booster needs to be replaced. Another dealer said the brake master cylinder needed to be replaced. I am in talks with the dealer to figure out how to proceed.

  • 63,000 miles
Driver made a sudden stop to avoid an accident on 2/16/15, engaging the brakes. Afterward the brakes alternated between being hard to push and being soft to push. Driver parked the vehicle 5 minutes later. The next time the car was turned on(approximately 60M later), the car began beeping and showing three error lights - ABS, (!), and the traction control symbol. After running diagnostics, the driver was told by a mechanic that the problem sounded exactly like a previously issued recall (tcp-D0H); however, Toyota has indicated that our model is outside the scope of their recall. Given that we have the same make/model/year car as the recall and the same issue described, the situation is highly suspect. In addition to insuring my own family's safety, I'm hoping to make sure this potentially dangerous brake issue isn't more widespread than Toyota has admitted.

Prius 4-cyl

  • 68,840 miles
As I was driving, I noticed that when I pressed on the brakes, the car would jerk forward before coming to a stop. Once stopped (but still turned on), the car made a buzzing noise I had never heard before. No warning lights came on, and the brakes did not squeak. An hour later, my husband drove the car home for me (I rode with a friend), and he reported that warning lights came on and the brakes did not work properly. In order for the brakes to work, he had to press very hard on them and also allow much more distance for the car to stop. He could have easily crashed into the back of another vehicle. He took the car to the Toyota dealership and was informed the brake booster assembly would have to be replaced. This is the same complaint as a 2010 Prius recall, but my VIN number was not included in the recall, so I did not receive a notice in the ail. Also, we had to pay $3008 to have the brake booster assembly replaced. The consumer referenced recall # 13V235000. Updated 02/11/16.

  • 120,000 miles
Driving on highway the ABS and brake warning lights came on and an alarm started sounding. I waited until light traffic applied brakes pedal felt like I was pressing on a brick, no braking occurred I pressed harder, the brakes became softer went to the floor and the brake pads grabbed hard on the wheels. There is no controlled braking on the car. Dealership says the brake booster pump failed, this is the same year model that had braking problems related to nitrogen in the break lines caused by a failed brake booster pump. The VIN is also very close to affected vehicles. Fortunately when this occurred I was in a position to navigate to where I could test the brakes in a fairly controlled environment. Had it happened in heavy traffic it would have almost certainly resulted in a serious accident.
