Brakes fail when applied steadily while moving on a wet or bumpy surface causing the car to continue forward unless the peddle is pressed again firmly. This happens on the city streets while moving in a straight line. This appears to be due to the known ABS problem in the 2010 Prius and was supposed to have been corrected byway of a software patch, which I am told by chuck patterson chico Toyota has already been done and no further ehlp could be expected from Toyota.

Noticed brakes pulsing at very slow speeds. Looked up symptoms online and determined it was from brake booster leak issue. Took to dealership but because no codes showed up on diagnostic machine, was told nothing wrong. (that was at 147,000 miles.) fast forward 6 months and warning lights came on while driving and braking became very spongy. Took back to dealership and needs brake booster pump and brake cylinder assembly replaced. Now has 155,000 miles and is 5000 miles past warranty. Long story short is that I was able to determine an issue long before their computer could detect anything. But because I'm now past warranty, I have to pay $2600 for repair.

I was driving on the highway at about 60 mph when the brake light, ABS light and slide light illuminated on the dash. I took the car to the dealer and they said it was the brake actuator. When I researched this, I found that it is a known problem totoyota and they did a voluntary recall. My question is why would there be a voluntary recall on a part that is vital to the safety of the car and has a known defect? because it was a voluntary recall they could arbitrarily select a cut off (150,000 miles) instead of ensuring the car was safe. This is only for 2010 Prius.

My brakes have failed due to a faulty brake accumulator and brake booster on my 2010 Toyota Prius. I noticed this problem when attempting to come to a stop at a redlight. The brakes felt spongy and unresponsive. I narrowly missed colliding with the car in front of me by swerving onto the shoulder. Toyota previously acknowledged this faulty part but claims that I missed the deadline by 35 days to get it fixed. The repair costs roughly $4,000 which Toyota has refuse do to accept responsibility for. I cannot afford to fix this and believe that it is irresponsible for Toyota to put their profits above the safety of its' customers. I do no this believe that it is ethical to put a deadline on a safety concern of this nature.

I bought this car around mid year of 2019, and when I first used it in the highway coming back from work, there was traffic and I noticed the breaks not responding well. This has happened many times since I bought it, in the streets as well. There's also a orange light saying that it needs maintenance. I have taken the car about 3 times to the person that sold it to me because he has a car shop and it still does the same thing.

While driving back from running errands my car's lights on the dashboard started to come on and noises started to start happening. I was lucky I was only a few streets away from my house so I decided to drive back home. The break was really hard to press. The brake felt like it was a rock and hard to press. I drove with my hazards on unsure of what could happen while driving. There was something wrong and the car started to beep and I was worried the car might fail to brake so I started to drive very slowly. The brakes were so hard to press. I took my car to Toyota the next day and they said there was a defect with my brakes. They had the vehicle for a few days and returned to me saying it was fixed. Needless to say this was a very scary situation to be in. I drive a lot. If I had been further away from my home this would have put me in a very dangerous position. I could've been stranded or drove on the freeway in this condition unsure of what was happening. My car could've stopped braking, I could've gotten into a big accident and injured other drivers around me. This is a very serious issue that should be recalled now and save other drivers! in California people drive up to 80 mph on the highway-if we are behind a car and the brakes malfunction you can imagine what will happen to the driver and anyone involved! when I heard Toyota was not recalling this on all Prius's that might be affected it really scared me. This is unsafe.

Hazard lights flashing when driving forward or reverse dependent on the speed of wheel rotation. I am told that my skid control ECU as well as the brake booster and pump are bad and need replacing. I keep reading about this issue, but Toyota says it is not a broad issue. It is not clear what systems have failed or what risk there is in driving.

The night before, everything was working fine. The next day, I start my car up at 4pm-5pm, first time I started my car and I have new lights on my dashboard. The ebrake light, ABS light, brake system light, and traction light. I release my ebrake and the ebrake light is still on. Concered I checked the break fluid and the 12V battery and those were fine. Drove the car around the block to see if there was an issue or if the lights were just on. The brakes were almost completely out the vehicle would only stop when I put my foot to the floor. I end up taking the vehicle to my local Toyota dealership were after four hours of looking around, informed me that it was the brake actuator and the booster pump. Which also came with a bill of $3000 to fix it.

Vehicle actuator brake pump assembly making squeaking barking noises when the brake is pressed down and held down the brake pumps back at me. I took to Toyota they charged me for running codes and two brake bleeds. Agknowledged that it's the break actuator pump assembly that is a extended warrenty but will not fix and charged me because the warning light system is not coming on. This should be a recall not an extended warrenty. My brakes bark and push back every time I brake. This doesn't seem safe to drive on the freeway and not good if an accident incurs because I had to wait until my brakes didn't work. Please make a recall and not just an extended warrenty.

My 2010 Toyota Prius slides while breaking when I drive over a bump or a whole the car slides while in motion on city streets or highways. These occurrences happen while driving straight or turning. This occurs all the time when the roads are dry and it is worst when it is wet outside, ice, rain sleet or snow.

- Michigan City, IN, USA

Brake/ABS and stability system failure. Possible actuator or accumulator. Touota knows there is a fault and hides behind a software update. System fails and causes unreliable braking with increased force to apply the brakes. Brakes apply so hard at times the rear passengers heads hit the rear seat.

- Hephzibah, GA, USA

I was making a left turn, creeping into a parking space, in a residential area. When I pressed the brake pedal to stop the car, the car accelerated instead. I then slammed on the brakes and the car accelerated again, causing me to go over the curb, over the sidewalk and knock down a fence and shed. I turned the vehicle off, some kind bystanders took the debris off the car so that I could get out. I then called police and the property owner, as well as my insurance company. I am honestly scared to drive the car again, as I do not want this unintended acceleration to happen again. I will be notifying Toyota, and the repair shop working on my car has already been informed.

Even though the break pads are new, the breaks are not working at all when vehicle is in motion. They do not feel tight. The vehicle looses stability in curves at a low speed ( slips) and keeps moving even when breaks are pushed to the end. All the break lights are on. There are several recalls regarding the breaks of this vehicle year 2010 and none applies to the vehicle VIN number. It it not reliable at all in the highway. In order to brake the speed must be very slow and the distance must be way more than normal

- Parkville, MO, USA

Even though the breaks seem fine, the electric break system does work at all. All lights are on and the breaks pedals feels loose. When I push the breaks the vehicle keeps going. The ABS warning light is on as well as all the other lights regarding to breaks and stability mechanisms.
