2011 Toyota Prius brakes complaints
Page 4 of 10: complaints 71 to 100 of 278, newest first, as owners wrote them.
Brake booster and brake booster pump assembly are faulty and failing. Brakes are still functioning, but will ultimately fail without warning, from what I have read. This is highly dangerous for myself and other motorists. I was driving last week and tried coming to a stop at an intersection. I pushed the brake pedal and the car hesitated and then jumped/lurched forward before coming to a complete stop. The brake booster is sounding every 30 to 45 seconds to try and build back the pressure it is losing. Toyota offered a "Customer Support Program" for these parts, as there's been numerous premature failures. Unfortunately, my vehicle no longer fits within the parameters of the support program (see attached). From what I've read though, Toyota has been negligent with replacing the brake booster under the support program. I have called Toyota Corporate and they have offered no reprieve and won't stand behind this faulty part. Toyota needs to be forced to recall these 3rd gen Priuses and ordered to replace the breaking system. Expecting customers to shell out between $2-3k to have the ability to safely break/stop their vehicle is ridiculous, especially when Toyota is more than aware of this issue. I was quoted $2600 over the phone to remedy the issue from an independent hybrid shop. I've owned 7 Toyotas and two have been Priuses. This 2011 is by far one of their worst to roll off the assembly line with numerous reports of breaking problems, oil consumption issues, and head gasket failures. They need to stand behind their product(s), especially to brand loyal customers.

Dear Mr; I own a 2011 Toyota Prius, and this week my brakes failed while driving down the highway. The ABS and Break lights and the ESP warning light on the instrument panel come on. The brake pedal is hard and has an intermittent hum in the engine area. The scanner gave the code C1391 / ACC PRESS abnormal leak error. I want to file a formal claim against Toyota for the failure of my car's brake system and request repair/replacement of my car's brake system. --------------------------------------------------------------------------------------------------------------------------------------------- What component or system failed or malfunctioned, and is it available for inspection upon request? BRAK SISTEMS / YES, IS AVAILABLE FOR INSPECTION. How was your safety or the safety of others put at risk? IT WAS DIFFICULT TO BRAKE / THE CAR WAS DEVIATED WHEN APPLYING THE BRAKE / I LEFT THE ROAD DUE TO THE RISK OF A COLLISION BY NOT HAVING THE ACTIVE BRAKING SYSTEM. Has the problem been reproduced or confirmed by a dealer or independent service center? YES / INDEPENDENT SERVICE. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO
All of a sudden, a few weeks ago, the ABS, TRAC, BRAKE, and brake warning lights all illuminated on my 2011 Toyota Prius, and the brakes became hard to press. Turns out, this is a known issue with this model of the Prius. DTC C1391 stored in the ECU. There is a defect with the brake booster/brake booster pump, and Toyota issued a Customer Support Program to extend the warranty on these two parts, but the program ended in 2021 and I am just now having this issue, although my Prius only has 115k miles. This should be a recall. I should not have to pay more than $3500 at the Toyota dealership to get this replaced when it is a defect with the parts that Toyota made (I should not have to pay ANYTHING). No dealership in the area wants to honor it either. Instead, they want to charge me $3500. And when I called Toyota Corporate, they brushed it off and told me "the program expired a whole 2 years ago" without even trying to work with me on the cost of the repair or anything. Complete let down from Toyota.
Brake actuator failed. Noise when applying brake but no code or dashlight. Looks like a common problem across prius 2011 model cars
The brake actuator on my 2011 Prius failed. Toyota issued an extended warranty of 10yrs/150k miles because they knew there was a problem with the product. I have less than 80k miles on my car and the actuator failed. I feel like I am being penalized because I don't drive my car as often. I contacted Toyota and was dismissed by them because I was outside of the 10yr window. The repair was $1737.98 in parts and $780 in labor by a Toyota certified technician.
The contact owns a 2011 Toyota Prius. The contact stated while driving 50 MPH, the check engine, service brakes, ABS, and the traction control system warning lights were illuminated. The contact parked the vehicle on the side of the road for approximately 3 minutes before continuing to drive to her residence. The contact stated on March 17, 2023, while her husband was approaching a traffic light, the brake pedal was depressed but failed to stop the vehicle properly. The contact stated that several warning lights were illuminated. The driver stated that the vehicle cruised to a stop independently. The driver decided to drive at a slow speed to the residence. The contact took the vehicle to the local dealer, where it was diagnosed and determined that the brake master cylinder, the brake pump assembly, and the brake booster needed to be replaced. The vehicle was repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 159,000.
Three lights appeared on the dashboard…code C1391. This has affected the braking system, and the traction control…and the brakes no longer regenerate the battery. The mechanic said “YOU MUST NOT DRIVE THIS CAR” until a $2,700 repair is made. There was, apparently, a service bulletin sent out in 2019, and was then extended until 2022…which we did not receive, although we’ve been at the same address since we bought the car. But our car did not develop this common issue until now…2023, and Toyota says it was not a safety recall, so they don’t need to fix it, or help us get it fixed. We believe it IS obviously a safety issue….since my brakes can go out at any moment.
On April 25, 2023 I started my Prius and as soon as I braked I knew something was not right. I noted that warning light were on. When I pushed on brake pedal, the resistance was very soft for about 2 inches of pedal travel. At that point the brakes grabbed very quickly. I drove to the Toyota dealership (Huntington Beach Toyota) and was informed later that day that the master and pump master cylinder needed to be replaced. The dealer said that Toyota did have a program to replace these assemblies, but had not issued a recall, which (in my opinion) it should have. I've had quite a few cars, most of which lasted for more than 200,000 miles. I've never had such a failure nor have I heard of one. Clearly there was a manufacturing defect that should have required a recall.
Brake actuator failed while driving down the road on Friday, 04/14/2023. The car became hard to slow down/brake. Brake light, traction control light, ABS warning lamp came on, and tire pressure lamp came on. Next day lights went out. Then again all lights as above came on while driving down the highway. That was Wednesday 04/18/2033. Took to Toyota dealership who confirmed brake actuator had failed. Car has 133,000 miles on it. Prius was in the repair shop at Norton Toyota of Tulsa, OK, from Thursday 04/27/2023 until Saturday 04/29/2023.
The contact owns a 2011 Toyota Prius. The contact stated that while operating the vehicle, the emergency brake and traction control warning lights remained illuminated, and the stopping distance was extended while depressing the brake pedal. The vehicle was taken to the local dealer who diagnosed that the hydraulic brake booster was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure and informed the contact that the vehicle was no longer covered under the manufacturer extended coverage for the failure. The contact stated that over the years the vehicle had experienced failures which included brake pedal stiffness and unintended acceleration after driving over bumps in the roadway. The failure mileage was 9,000. The VIN was not available.
on 4/12/2023, I was driving near an intersection and the e-brake and abs light both came on and the brakes on my car were suddenly twice as hard to apply, with a "soft" feeling to them. I was able to pull into a nearby brakes plus location. My younger sister and friend were in the car at the time. The problem has been reported by a Toyota dealership in California. The component was inspected by a repair associate at Brakes Plus and he confirmed that the electric brake booster on my prius was shot. There were zero warning signs of the problem prior to the incident.
Brake booster and brake booster pump failure
It is very unfortunate that the brake booster extended warranty was declined by Tustin of Toyota specially after having my vehicle in their hands for another recall when the warranty was active. This is something I can not wrap my head around. I would like to speak to someone in regards to this dealer. Who can I speak with?
Reporting an issue related to Toyota's CUSTOMER SUPPORT PROGRAM BULLETIN (ZJB): REPAIR COVERAGE FOR BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLIES ON CERTAIN 2010 MY PRIUS AND CERTAIN 2010 MY PRIUS PHV VEHICLES. Finally got a C1391 error with the respective dash lights. Increased hissing/pumping was occuring from the brake assembly for about a year before hand until the code/lights happened. Customer Support Program Bulletin is closed but hoping it reopens.
After approximately 6 1/2 years of owning this 2011 Toyota Prius Hybrid (purchased in 2012), the brake pedal went completely to the floor and there was no braking. The brake fluid was completely FULL. Intermittently, this would occur, but brakes would come back operational in a few minutes. In 2022, the brake lights on dashboard started lighting up intermittently and go off. I had the complete brake pads, etc. replaced in June 2022. Last 1/2 of 2022 the entire brake dash lit up. I got into Toyota dealership 1/12/2023. They said the complete brake Master Cyclinder and Brake Pump replacement was required. They got the dash lights off. This car has only 133,023 miles. I finally checked the internet to see this is a TOYOTA issue! A recall on this brake assembly should be issued! I was unaware of this 5 years ago. This could cause a serious accident and should be fixed at Toyota's expense!
As I'm sure you have heard from the numerous complaints on the internet the ABS on this vehicle is having issues. The repair is over 3,000 dollars. Toyota needs to recall this brake pump. I can't pay 3,000$ to stay safe in my vehicle. They made a defective part and were somehow allowed to extend the warranty instead of recall it. My vehicle is under the mileage but over the years so I was pretty much told too bad. This needs to be addressed at a actual road safety level which is why I am writing you. Thank you for your time.
ABS actuator and pump failing, which requires much harder pushing on the brake pedal to come to a complete stop. This part is supposed to last for the lifetime of the car and is now failing roughly 11 years after purchase. I took it to the Toyota dealership and was quoted $2,500 to repair it.
The ABS Actuator and Booster failed with diagnostic error code C1391
I have reported this once and numerous times to Toyota. I even paid to "fix" the problem. My daughter was driving and all the dashboard lights came on and the brakes do not work. It's doing it again after they supposedly "fixed" it. My family is at risk! If anything happens, I will seek legal action. I can't believe a company as big as Toyota wont take responsibility. And that a recall wont be done. I've seen numerous people report the same issue. PLEASE do something.
ABS warning light came on, followed soon by a beeping warning sound. Brakes felt odd. A few minutes later, complete loss of brakes.
brakes in the car failed due to loss of hydraulic pressure/ brake acuator system. toyota issued a service bulleton for this problem approx 2017-2021 and the dealer and corporate would not honor the repair to my vehicle each time i brought the car in for inspection after experiencing constant issues with my brakes. the brakes finally failed and i could not stop the car while driving at interstate speeds. the vehicle was inspected by a private mechanic and confirmed the failure that toyota refused to honor. no warning lamps or messages in the car until the brakes actually went out while the car was in motion at interstate speeds. symptoms first appeared in 2017, but the dealer insisted nothing was wrong even though i demonstrated the symptoms to their mechanics in person. i reported the dealerships behavior to corporate and they did not help. they claimed the brakes were ok because the car's computer did not give an error code "yet".
The contact owns a 2011 Toyota Prius. The contact stated that the ABS warning light was illuminated on the instrument panel. The contact stated that he had to apply extra force to the brake pedal while attempting to stop the vehicle. The manufacturer was notified of the failure and informed him that the vehicle was under warranty; however, the warranty had expired.

The contact owns a 2011 Toyota Prius. The contact stated that while driving at various speeds, the brakes failed to operate as needed upon depression with several unknown warning lights illuminated. The contact took the vehicle to an independent mechanic where the vehicle was diagnosed with a defective brake control dynamic system. The contact was referred to the dealer where they confirmed the failure and provided her with an estimate for the repair. The manufacturer had yet to be notified about the failure. The vehicle had yet to be repaired. The failure mileage was approximately 155,000.
The contact owns a 2011 Toyota Prius. The contact stated while driving 25 MPH, the ABS warning light illuminated on the instrument panel and the vehicle failed to brake normally. The vehicle was taken to the dealer and the contact was informed that the brake accumulator and brake pump needed to be replaced. The vehicle was not repaired. The vehicle was not under warranty. The manufacturer was not contacted. The failure mileage was 156,000. The VIN was not available.
The contact owns a 2011 Toyota Prius. The contact stated that extra effort was needed to stop the vehicle due to the brake pedal being depressed to the floorboard. The contact stated that the traction control, ABS, and brake warning lights would appear upon starting the vehicle. The contact had taken the vehicle to an independent mechanic where the vehicle was diagnosed with a defective ABS actuator control unit and the contact was provided an estimate for the repair. Neither the dealer nor the manufacturer had been notified of the failure. The vehicle was not repaired. The failure mileage was approximately 133,000.
The contact owns a 2011 Toyota Prius. The contact stated when his wife turned on the vehicle the brake, abs, and traction warning lights illuminated on the instrument panel. The contact stated while she was driving at 10 MPH, she noticed that the brake did not have pressure as usual. The vehicle was diagnosed at an AutoZone, and they stated that there was an abnormal ACC (C1391). The manufacturer was contacted, and they stated that the vehicle was out of warranty. The failure mileage was 178,000.
This issue started happening intermittently beginning in April 2022. The ABS/Traction Control/Emergency brake lights came on all at once and the car lost power braking ability. The car would stop, but it required much more force on the pedal and an increase braking distance. Folsom Lake Toyota Service said that there wasn't anything they could do if the warning lights had turned off and to try to recreate the issue. It happened again in May 2022 while my daughter was driving the car back from Tahoe. She was not hurt, she avoided an accident. The car returned to normal operation after it was parked for one day. It happened again in July of 2022. This time the brakes hissed when applied. Called Folsom Lake Toyota to have it looked at. They diagnosed it as error code C1391 and the master cylinder (acctuator) and brake booster needed to be replaced. The repair was $3200, so we took the car to Roseville Toyota for a second opinion. Roseville Toyota was able to recreate the issue and the brakes completely failed at their service center. Their estimate was for the same $3200 repair. We called Toyota Corporate and they responded that there was a Toyota Customer Support Bulletin ZJB sent out for this issue. The bulletin extended the factory warranty on the parts for 10 years or 150,000 miles. The bulletin describes the exact code and symptoms our car experienced. Our car is 11.5 years old and 113,000 miles. In speaking with Toyota Corporate, their position is that they already extended the factory warranty once and since that our car is past the 10 years, they refuse to consider my complaint or provide any "goodwill" assistance with the repairs. Toyota knows there is an issue with their master cylinder and brake booster parts. They set an arbitrary warranty extension date rather than recalling the cars. Toyota is waiting for the brakes to fail BEFORE they fix the problems. My daughter could have been seriously injured or killed, or she could have killed someone else.
safety brake booster and actuator concern. the car abs, master cylinder brake lights are on. the booster is making hissing air sounds and the brake pedal vibrates. the code is 1309 maybe more.. this is a problem with thousands of prius and costs thousands to repair. Toyota extended this warranty to 10 years 150k mine 2011 so lost the repair last year but only has 150k miles.
My brake accumulator pump has begun running much more frequently than it should. Upon extensive online searching, I learned that this condition is warning sign of an eventual failure of the brake booster pump and/or master cylinder which will cause brake failure at an unpredictable time when the brakes are applied. I understand that this condition is known by Toyota and has been addressed by "warranty enhancement ZJB". However, my car is outside of the cutoff age/mileage. The president of Capistrano Toyota in Southern California made this problem known to you with an urgent letter dated 9/19/19 and expressed why this NEEDS to be a recall issue, not just what it is now. The reason is because not only has Toyota time limited repair coverage, they would not do the repair until failure occurred....a totally illogical and dangerous plan. I should not have to pay ~$3000 to have this well-known problem repaired at my own expense just because the invitable failure hasn't happened yet, and I'm not within Toyota's arbitrary time limits for having the repair covered at no cost. The symptoms I am experiencing are precisely those that are the precursor to this known failure. Why has the federal safety agency not acted to force this issue to be a full recall? You are putting lives at risk by not acting in a timely fashion given the Toyota dealer's warning I mentioned above.
