ABS and brake lights "turned on" on the dashboard while driving along freeway. Had to push the brake pedal harder to stop the car. Search online on what might be causing the warning lights, it was found out that so many Toyota Prius car owners were having the same issue. The symptom was caused by either faulty accumulator or master cylinder/actuator.

The brakes make sounds when pressed. Look into the internet and Prius chat forums and taking to local mechanic and found the brake actuator is faulty and need replacing asap.

I was driving to my house and the brake pedal went to the bottom. Several lights appeared on the dashboard. I was driving in the highway and fortunately there was an exit and I could get out of the highway and I manage how to stop and I did not crash. The story could be another if I was driving faster. The next day I took it to the Toyota dealer and they told me that the problem was the booster pump (attached you can find the estimate). I was shocked when I found how much was going to cost me. My car has never had a problem and all oil changes had been at the same Toyota dealer. I have never taken the car anywhere else. Investigating I found that this model Prius 2010 in 2013 had a recall for this same problem affecting 82000 people. I am using the car with because I have to go out to work every day for the sustenance of my family and with a constant concern of having an accident and causing death to other people including myself, I need the help of Toyota to pay for the entirety of arrangement I already spoke with Toyota headquarters and they said that they will not help me with the cost of the repair, it is really expensive and it is not my fault. Does Toyota have to wait until there is an accident" or injury or dead people".

I stated to the glendale Toyota dealer in California that I hear and feel a buzz/click when I step on the brake and they informed me it is the brake actuator and warranty expired in December 2017. I am requesting is an extension to this warranty or voluntarily make it a safety recall. It is very dangerous and expensive to fix.

Letter from congressman olson on behalf of constituent regarding Toyota brake recall on her 2010 Toyota Prius. The consumer was concerned about not receiving a notice for the safety recall for the brakes.

- Katy, TX, USA

Brake pedal goes to floor. Brake light is on. Dealer says accumulator pump is bad. There is a recall for this item. They replaced it under recall in 2014 and refuse to do it again. Quoted $2000 to repair. Called Toyota customer service and they won't do anything either. It is a safety issue and still having the same safety issues is not ok. I am 6 months pregnant and cannot afford to fix an item that should be covered for life of the vehicle due to this recall.

My brakes recently stopped working as they normally do (you had to press extremely hard on the pedal to get it to stop) and several lights came on the dashboard. Prior to this the car was making a very strange noise when you start to push on the brakes. Not like a typical squeaky brake sound. I took it to Toyota and they gave me a quote for $3,700 stating that I needed a new brake cylinder assembly. I discovered a recall for 2010 Prius for the exact diagnostic code and they said my Prius was not covered by the recall. When you "reboot" the computer on the Prius, the lights and brake problem go away. This appears to be a significant problem with the 2010 Prius from what I have read on-line and Toyota is not acknowledging it. It's also a very costly repair that seems to be easily fixed when you reboot the computer on the car. What is going on" how many people are paying Toyota for this fix that appears to be a wide problem with the vehicle that should not be happening"

After regular check-ups and maintenance at 90000 miles and 8 years of driving, all of a sudden three brake lights came on, the ABS, hand brake, and skid control lights all came on. At this time the braking issues seem to be less responsive braking and slight jerking when putting constant pressure on the brakes at low speeds. When brought to the Toyota dealership, they noted that there are no issues, however the master brake cylinder is likely to fail soon.

I took my Prius to the dealer because the brake light was on, to resolve the problem they replaced my master cylinder and booster on my 2010 Prius. I asked about a recall for the parts. I was told no recalls, I found that there is a recall for 2010 Prius. T-cp-dom date of issue July 1, 2013. The recall is for the same problem I had

The traction light, the ABS light and the brake light appear on the dash. I have already paid the mechanic approximatly $1,500 for repairs and now I am told I need the ABS brake booster which costs an additional $2,546.26. This part has been recalled on other 2010 Toyota Prius models, but not mine. I cannot afford this fix, so I am driving my car as it is. Brake pedal acts differently each time I use the brakes.

I was on the freeway in traffic, going 60 mph. There was road construction coming up ahead. I depressed the brake pedal and nothing happened. The car didn't slow down at all and I crashed into another vehicle. My car was manufactured when the 'voluntary safety recall' by Toyota was supposed to address this, but I received no notification, nor did thousand oaks Toyota, where I had the car serviced, communicate about it.

I've counted at least 30 brake booster/actuator complaints on this site year to date for the same issue on this model year car. Our issue is the same as everyone else. Just under 150K miles, brake, ABS and traction control lights came on my daughter's car (we are original owners) as she was driving home from work. Non responsive brakes, only rear brakes engage if you push the pedal to the floor of the car. Took to dealer who diagnosed dtc C1391, accumulator leak malfunction. Our car was not included in original warranty enhancement (manufacture date of 1/2010), so price quoted was $4814.66. Our daughter cannot afford, so we called Toyota warranty who offered us $2007 as a measure of good will, but no more. This is a serious safety issue, beyond ridiculous that some cars with the same defect had the warranty enhancement program available which paid for the entire repair, yet most others like us were denied the fix and are facing astronomical repair bills that many cannot afford, nor anticipate on a car such as a Toyota. The brakes failed while my 22 year old daughter was driving - that could have gone so very wrong.

While driving on a bumpy surface the brakes slip when applied. Stopping ability is reduced. This happens on a regular basis, on surface streets and highways. I have noticed it while stopping in a straight line, but it may also happen while stopping on a curve.

The contact owns a 2010 Toyota Prius. While driving approximately 30 mph and depressing the brake pedal to slow down the vehicle, the pedal became loose. As a result, the vehicle continued moving and the anti-skid, brake, and ABS warning indicators illuminated. The contact was able to bring the vehicle to a stop by depressing the brake pedal multiple times. The vehicle was taken to cavender Toyota (5730 northwest loop 410, san antonio, tx 78238, (210) 681-6601) where it was diagnosed that the power booster failed and needed to be replaced. The vehicle was not repaired due to the repair fees. The manufacturer was notified and informed the contact that the VIN was not included in any recalls; therefore, no further assistance was offered. The approximate failure mileage was 85,000.

ABS, brake and traction control lights on. Code C1391 abnormal leak in accumulator.

- Miramar, FL, USA

C1391 - ABS system failed

- Derwood, MD, USA

Brake actuator has failed. Traction control, ABS, brake lights illuminated on dash. More effort needed to engage brakes. This affects the regenerative braking as it no longer charges on braking as it was designed. Checked Toyota website for recalls since this is safety related, and there are none. Which is quite disturbing. I've researched Prius forums and this seems to be an ongoing problem. Toyota issued a recall for the generation 2 model, however this seems to be a problem for generation 3 models as well. The problem did occur when on the highway traveling at 60 mph.
