The abs warning came on and we took it to the dealership for diagnosis. Apparently there was a "warranty enhancement program" attached to this car for this specific problem, the brake actuator assembly". However, even this is a known manufacturing-defect, Toyota is refusing to pay for this service because they reasoned that this has fallen out of their warranty dates, which included 2 types of coverage: primary coverage ended 12/31/2017 and secondary coverage for car less than 10 years old from the first use or 150,000 miles, whichever occurs first. According to Toyota, the first use of my Toyota Prius is 10/13/2007, and 10 years from that date is 10/13/2017, which came before even the deadline for primary coverage. This "warranty enhancement program" is for 2004-2009 Prius. You would think it will cover at least until the last manufactured car of 2009, but that was not the case. Also, the dealer and the manufacturer both stated that they can't fix it unless you actually have the abs light turned on and it warns about the issue. You would think if that light comes on, it will be very dangerous if you are driving 60 mph on the freeway and you can't brake! Toyota definitely did not think so. The repairs I was quoted for this particular problem is $2800 + tax, which is expensive and I can't afford to pay for it. I feel ridiculed because this is a manufacturing defect and it is not something related to wear-and-tear. Toyota acknowledged that this is a manufacturer defect and the reason they refuse to pay for this service is because it fell outside of the "extended warranty period". We did not even receive the notice to begin with; I found this out on the internet and apparently, a lot of people have this problem with their vehicles and Toyota either dragged out the timeline of repair so that it will surpass the deadline stated on the letter of the program.

Failure Date: 03/19/2018

I was driving at about 35 mph and all of a sudden my brakes stopped working. The brake , abs and traction lights came on all at once. I somehow made it home but I could have easily crashed. I had my 9 year old in the back seat and he also got very scared. Now I cannot drive my car and the brakes feel as they as stuck and very hard. I took my car to a reputable mechanic and he told me it is giving him code c1391. This is the same problem that the 2010 Prius had under the recall. My Prius is 2011 and not under the recall. I feel that the 2011 should be under recall because many thousands of lives are in danger now.

Failure Date: 03/09/2018

Brake actuator problem on my 2005 Prius. I have this vehicle I have been driving for since October and has always made this noise from the front like a pump running. The car itself did not have an issue until recently the abs light and brakes started acting up. I have found out that Toyota had a warranty enhancement that expired in December this year. I had called a local dealer when I purchased the vehicle to see if there was any kind of recalls and they said none for this vehicle. This part is a known part that fails and when it does it could end up making the car like a run away train with no brakes depending on your speed. I tried contacting Toyota today but got pretty much no where they are saying that I need to bring it to them and pay them 3,000 dollars. The repair is not possible to be made by anyone else without a special scan tool the cars brakes will sometimes go away completely and the pedal becomes stiff and the vehicle will not brake. If there is any other info needed please let me know.

Failure Date: 02/12/2018

Abs light stays on, I have no brakes when emergency braking, there was a Toyota Prius recall on brake master cylinder and booster pump but Toyota said it was not for my vehicle. My problem is exactly the same problem as other Prius brake recalls but Toyota will not cover it. Less then 65,000 miles on the car . How can a master cyl be bad by now, they usually last over 100,000 miles. Very unsafe , and may kill someone. This should be covered by Toyota with all the other brake recall problems with this year and model. I had to slam on my brakes but my car would not stop causing me to run into a wall at the baltimore harbor tunnel. This is a recall and letters were sent out by Toyota about this faulty braking but now Toyota will not honor the recall.

Generation 2 Toyota Prius brake actuator. At slow speed, the brakes became inoperable and would not stop the car causing me to rear end a truck stopped in front of me at a stop light. All of the brake, abs lights came on the dash. 2 separate trips to the dealer to have the brakes checked resulted in no error codes found. Today 2-8-18 the dash lights all came on again, and the dealer said the computer code is stating faulty brake actuator which could result in total brake failure.

Failure Date: 10/07/2017

My car had the abs warning light on and I heard a strange noise in the engine compartment. Last year. On October 7, 2017, I was driving on the highway and another driver cut me off, so I had to break hard. The car pulled hard to one side and I hit the retaining wall. Fortunately, the damage to the car was on the bumper cover only, and I was not injured, so I was able to continue driving. The dealer ran diagnostics on my car after the crash and reported I needed to have certain parts replaced. Toyota safety recall 13v-235 describes exactly the symptoms my car shows and requires replacement of exactly the same parts. The only problem is that my car's VIN does not fall in the range Toyota reported in the recall. Apart from that , the problem is the same. My accident could have been very serious had the retaining wall that stopped me not been there. I could have been in the center lanes and the story would have been very different, even with me surviving the accident.

On October 7, 2017 a driver cut me off on the highway, I pressed my brakes hard and the vehicle pulled to the side and I hit the retaining wall. The impact was not too hard and I was able to continue travelling. The abs warning light is on and I hear a strange humming noise under the hood. The dealer ran diagnostics and said I needed to replace two main parts in the brake system. I found a Toyota safety recall 13v-235 affecting other Prius 2010 that describes exactly the same problem and requires replacement of exactly the same parts indicated in the safety recall. The only problem is that Toyota reported this problem in vehicles of the same year and model, but my car's VIN was not included in their indicated range. Thank you for your help.

I was in an automobile accident where I rear ended vehicle in front of me. I tried to stop but the vehicle would not stop or even make an attempt to slow down. My ankle suffered a severe twist from trying to apply brakes. There was plenty of room to stop but the brakes would not react to slow down vehicle. There was a car coming in the oncoming lane so I could not go around vehicle in front of me. My vehicle was in motion in the city and I was going straight. The pavement was a little rough and my abs light was going off and all I could do was hit vehicle in front of me due to brakes failing and not slowing me down.

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.

Car loses braking ablities when going over rough terrain or slippery terrain. The abs initiates but then stops. The abs light can be seen on the dash (normal). This action is very frightening. The stopping distances have left room for error, so no accidents yet.
