2013 Toyota Prius complaints

**What component or system failed or malfunctioned, and is it available for inspection upon request? **How was your safety or the safety of others put at risk? **Has the problem been reproduced or confirmed by a dealer or independent service center? **Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? **Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? PASSENGER SIDE SEAT BELT The passenger side seat belt became folded and stuck. It would not enable the person to pull it and attach it to the clasp. When my little boy did pull it in the clasp it was an extremely snug fit. I had 3 people try to unfold it. Finally someone had to slice it so that we could at least get part of it to work and go into the clasp. The shoulder strap did attach properly it is just the stomach strap that is not working properly. I brought it to the Toyota dealership to see: 1. If there were any recalls on it. 2. To see about getting it repaired. The dealer said that there were no recalls on that item and that it was indeed broken and it would cost over $500 to repair. I have not brought it the manufacturer. I don’t know where the manufacturer is located. Are they in Japan? The only warning signs were when the seatbelt was not properly attached because it did not properly fit on my passenger.

Took vehicle for state inspection on 2/13/2024, failed inspection because of brake warning lights. Slip indicator, Electronically controlled brake warning light, Brake warning light, Anti-lock brake system, and Low tire pressure lights are all on. I have looked into it, and it seems the brake actuator/booster used to be under warranty, however since this is a 2013 in 2024 with almost 210k miles on it, it no longer qualifies for the original recall.

I was driving my 2013 Toyota Prius last week when my my dashboard lit up with the Brake, ABS, and Traction Control lights all going on simultaneously. Shortly thereafter, I attempted to brake, as a car stopped in my lane to make a left hand turn, and the brakes did not engage as they should. I had to press twice as hard for very limited braking; my braking distance increased substantially and I narrowly avoided hitting the turning car in front of me. I drove it directly to the dealership and they diagnosed it as a failure of the Brake Master Cylinder Assembly and Brake Booster Pump Assembly (code C1391). Upon further research, I found that Toyota had previously acknowledged the problem and issued a warranty extension (Customer Support Program ZJB) that covered up to 150,000 miles or 10 years. While my Prius is well below the mileage requirement, I am beyond the 10 year limitation by less than 6 months. By Toyota's own admission, the Customer Support Program covered approximately 946,100 vehicles. This part failure put the safety of those on the road in front of me—and me—at risk.

The 2013 pruis has developed the notorious brake booster fault triggering the brake light abs light and traction control light to stay illuminated. Toyota has many complaints about this brake booster issue and needs to recall and fix this issue as they have done on other Toyotas. This is leaving owners with a $2500 repair or having to take a big risk driving these cars with a big prevalent brake issue that Toyota needs to be held accountable for.

The contact owns a 2013 Toyota Prius. The contact stated that after several days of torrential rainfall, the contact noticed there was water in the tire and 12-volt battery compartment. After having a routine oil change at an independent mechanic, while the contact was driving, the vehicle lost power steering functionality. The power steering warning light illuminated after the failure. The driver was able to restart the vehicle and pull over to the side of the road. The contact called Roadside Assistance and was informed that there was a code for the hybrid battery system that needed to be checked. The contact noticed that water might have entered through the rear passenger’s side brake light. The contact removed the water with a sump pump. The vehicle was towed to an independent mechanic who was unable to assist. The vehicle was towed to the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 119,000.

While driving on a highway overpass, the brake booster system suddenly failed in my 2013 Prius on March 12, 2024. The vehicle displayed Diagnostic Trouble Code (DTC) 1391, which is a known issue with Toyota Prius vehicles. Toyota offered an extended warranty for this repair that expired in August of 2023, admitting that their vehicles contained faulty parts. There have been several complaints about this known issue and an investigation needs to be reopened regarding this ongoing issue. Will someone from the NHTSA please start an investigation or facilitate in any way to get an investigation into to this reoccurring issue. Brakes matter and society is depending on government and corporations to be transparent and ethical. The FTC, BBB and Attorney General’s need to act on behalf of everyone in keeping our roads safe and holding Toyota accountable again. This is absolutely a major safety issue that should be covered by Toyota regardless of when it manifests.

- The Hydraulic Brakes, or brake actuator, failed. I have taken it to my local mechanic and they confirmed. - My brakes are operating at a substantially reduced capacity - an emergency mode that only allows for the front brakes to work - Yes, my local mechanic confirmed the problem - It has only been inspected by my local mechanic - yes, several warning lights came on while I was driving.

The brake pump which pressurizes the nitrogen accumulator kept cycling on more and more frequently until it was cycling on every 8 seconds after stopping while trying to maintain pressure in the automated brake system. Brake pressure began pulsating when applying brakes and was slowly becoming noticeably more unstable as time progressed. I could also hear a steady flow of fluid through the booster/master cylinder unit. This seems to be a common issue often being discussed online in forums like “Prius Chat”, an online car community describing the characteristics of the power brake system in this vehicle before it fails as well as with a number of online youtube mechanics replacing these units. It seems as though the solution is for dealerships to charge in many cases more than 4000 dollars to replace both the entire “Brake Booster Assy, w/Master Cylinder” and the “ Pump Assy, Brake Booster” as standard procedure. I believe it’s the ‘Brake Booster Assy, w/Master Cylinder’ unit causing the issue, I do all my own repair work on my vehicles and I partially disassembled the booster/master cylinder unit, upon removing the cover for the circuit board control unit integrated into the assembly I discovered evidence of an overheated or corroded circuit board. The soldered pins for the main bus connecting the wiring harness to the circuit board showed possible charing and discoloration as well as very dull colored soldered joints. This was also observed at the bottom of the circuit board

See attached document for complaint

Power brake, electronic systems around braking, brake actuator and assembly. Gradual degradation of brake power and resistance resulting in complete loss of power brakes system. Vehicle's brake system no longer works as designed. Vehicle has been inspected by technician. No warning lights or lamps in advance of total brake system shut down.

Loss of brake function coming to a red light. 5 warning lights illuminated. Also noticed a noise that appears to be coming from the brake pump that is cycling every 3-4 seconds. 1) Masterv Warning Light. 2) Brake System Warning Light 3) Brake System Warning Light 4) ABS Warning Light 5) SLIP Indicator I have called the Toyota service advisor and will be getting a quote for repair. Apparently, I have found out that there is a class action inquiry that I would like to be included in.

Several dashboard lights came on suddenly when braking. Upon speaking with the dealership it was determined that I experienced sudden brake actuator failure resulting in loss of braking power. Fortunately, it was not complete loss of braking or it could have been dangerous to myself and others on the road. Upon researching this issue, I have discovered that brake actuator failures are not uncommon in Toyota Prius models, and there have been numerous reports and complaints from other owners facing similar problems. This raises serious questions about the integrity of the brake system in these vehicles and the potential for widespread safety hazards.

The brake booster system suddenly failed in my 2013 Prius. I was driving when the ABS warning light, the brake warning light, and slip indicator light came on. The brakes became soft and it was difficult to stop the vehicle. I had it towed to a local, independent mechanic and the entire brake assembly had to be replaced. Toyota offered an extended warranty for this repair that expired in August of 2023, admitting that their vehicles contained faulty parts. This is absolutely a major safety issue that should be covered by Toyota regardless of when it manifests.

As I was driving, the ABS, Brake, and Traction Control lights all illuminated on my dashboard and have remained on since. I took the car into the dealership to get a diagnosis, and they told me that I had a accumulator leak and needed to repair my brake master cylinder and replace the brake booster pump assembly. This is apparently a known issue with Toyota Prius, as hundreds of others have discussed this in various forums.

I am the joint title owner of a 2013 Prius. This complaint is Case # [XXX] at Toyota. Our [XXX] daughter has full-time use & possession of this vehicle. In her own words, this is what happened: “I was driving on the [XXX], about to merge onto the [XXX] in Los Angeles. This is an extremely traffic-heavy interchange. Approaching the stopped car in front of me, I applied my brakes. The brakes did not work properly. I had to press the brake pedal much harder than I normally do, & my car kept going for another two seconds or so before stopping. Three dash lights came on – ABS light, brake light, & light with the swerving car symbol. There was a ‘puffing’ type of sound from the brake pedal that lasted about a second, then stopped for about two seconds, then started again, & so on. That sound would come out of the pedal area regardless of whether I applied the brakes. Frightened by the brake failure, I pulled off the freeway in downtown L.A. I turned the car off & let it sit for a few minutes. When I turned it back on, the same three dash lights came back on, & the car was still not braking properly – still the delay, the need to press harder than usual, & the sound. I drove directly to my Toyota dealer. It was a 35-minute, nerve-wracking trip.” The dealer found "CODE C1391 ABNORMAL LEAK IN ACCUMULATOR." Cost of repair was $3,163.12. Note also that in 7/23, she had taken the car to the dealer with the "SAME sound" (her words) when braking. The dealer could not duplicate the problem.

I pushed on the gas, the car started mildly shaking under the hood( the engine) then I released my foot off the gas and the shaking ceased. I the. Attempted to accelerate again and the car started violently shaking so I released my foot from the accelerator and turned the car while coasting onto a side road where I traveled back home. Had the car towed to mechanic. He said the engine needs to be replaced as the pistons are damaged. My car has 196,000. I will have the engine replaced as my other 2012 engine just did the same similar thing and I am out two Priuses with blown engines. There were no warning lights and no previous issues or signs prior to the catastrophic events.

ABS Brake Warning Light On-stays on-this just happened within last 2 weeks. Not sure on safety measures but unsure if I keep driving it the brakes will just give out. The problem has been confirmed and seen by Tire Max but no diagnostic tests were ran. The just saw the light was on. No one has inspected the vehicle component by the manufacturer, police, or insurance company. No warning lamps prior to the problem but the ABC Warning light stays on while cranked and it first appeared about 2 weeks ago. I do want to add that a similiar recall or warranty had been put out by Toyota on Sept 4th 2020-(T-SB-0089-20) for 2012-2014 Prius V & C stating: "Some 2012-2014 model year Prius V hybrid vehicles may exhibit a condition where the brake, ABS, and/or TRAC warning lights are on and/or a Check VSC message displays. Diagnostic Trouble Codes (DTCS) C1391, C1252, C1256, C1253 may be stored. This condition may be caused by a small internal brake fluid leak inside the brake booster assembly with master cylinder. The warranty was for Prius V or C but my Prius(no V or C) has been affected with the same issue but Toyota will not honor this warranty or recall due to the problem not showing as specific to my vin#. So I am reporting this problem so it can be submitted that there is a similar problem with my Prius as well as the Prius V or C so others could submit their problem as well. I cannot afford to fix this myself. I need Toyota to back up their cars.

ABS , brake. Anti lock lights

I was driving home on a busy street in Houston, TX on a clear day. I tried to slow down due to traffic & the following warning lights appeared on the dash: red brake system warning and yellow brake light, ABS, brake system warning light & the slip indicator light. Right after, I came to a red light & started to brake, the car felt like it was on ice and couldn't stop properly. Fortunately I didn't have to come to a complete stop because there were many cars in front of me and the light turned green. when I stopped applying pressure to the brakes the car sort of shook side to side. Each time I had to brake, the car felt like it was on ice, I had to put the hazards on & give myself a very large amount of room to stop the car. While at a red light I turned the car off/on; no change in the dashboard lights. I turned onto a street w/ less traffic; pulled over, turned the car on/off again and no change. I was less than a mile from home so I drove the rest of the way w/ my hazards on & never went faster than about 15 mph; even at that speed the car took too long to come to a complete stop, it felt like I almost had no brakes at all. Thank God I wasn't on the highway w/ no brakes!! This is a HUGE safety issue, someone could die or be seriously injured. Had the car towed to a Toyota dealership on Mon 1/15/24; they said there was a brake fluid leak in the master cylinder & malfunction of brake booster pumps, the code was C1391; both parts needed to be replaced. Total cost for repairs $

ABS, Brake, Trac warning, and brake lights turned on. When I used a diagnostic device, I read the code C1391 code. The brakes of the vehicle are not working properly. Upon my research, I found that several factors can trigger the C1391 code, including a faulty brake accumulator pressure sensor, low brake fluid level, brake system leaks, issues with the ABS pump/motor, or electrical problems within the brake system. This problem has many safety implications. The brake system is fundamental for vehicle control and stopping power. Any compromise in its performance poses a risk to the driver, passengers, and others on the road. Prompt action is necessary to investigate and rectify the root cause of the C1391 code to ensure the continued safety of affected vehicles. I think Toyota company should issue a recall for this faulty system.

The rear right wheel broke off when going in reverse, leaving driveway (low speed). Towed to a garage. Was told that the rear frame member had rusted through. Had no warning of this -- car is used regularly and had been inspected several months ago. EXACT SAME THING HAPPENED TO ANOTHER COUPLE WE KNOW WHO ALSO OWN A 2013 PRIUS -- rear wheel came off because the frame member rusted through. Happened about a month before ours. They too were going in reverse, slowly, coming out of a parking spot, after driving 40+ miles to Boston. Car needed to be towed and rear frame member replaced. Repair for us cost $1300

While driving on the freeway, all of a sudden the ABS, Slip Indicator, Brake, and Brake System lights lit up on the dashboard. I immediately switched lanes to one that had no cars in front/back of me since I was going about 55mph. I tested the brakes since I saw the brake lights appear. It felt as though when the brake pedal was pushed, they didn't activate until you reached a certain point, almost to the point where the pedal needed to be fully pressed to stop. It didn't feel like the brakes were fully functional and behaving in the way they were prior to the lights appearing. I was afraid the brakes would give out. Then I noticed a whirling/hissing sound that was consistent. The sound was easier to hear when the car was at a complete stop but it could still be heard while driving. We took the car to a local Toyota dealership/service dept to get it evaluated. They diagnosed the car saying it needs immediate attention and is not safe for driving since it involves the brakes. The repair invoice stated VARIOUS BRAKE WARNING LIGHTS ON C1391.

ABS, Brake, and Traction control lights are on alongside a constant beeping. I have lost regenerative braking and it now takes more effort upon the brake pedal to come to a complete stop. I am in fear that the brake system will go out completely, causing damage to myself or my children.

Brake pump failed while on the highway. Brake functionality and braking distance changed drastically while driving high speeds. Dealer confirmed that the breaker pump and master cylinder must be replaced with a new assemblies. There was no recall for this failure, but a Toyota Customer Support Program for replacement of this brake assembly was active for reports of this failure only before April 2023. Toyota dealerships are not obligated to cover this replacement or make customer aware on any suspected vehicle unless the failure was present before April 2023. Warning lamps only appeared at brake pump failure - not before failure.

BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLIES. making a buzzing noise. cost to repair is estimated to be 2500 or more. Toyota even has a bulletin for it, but they did not inform the public, because the part is very expensive and difficult to fix on a prius. since it has expired, we are out of luck.

The brake accumulator and brake actuator failed while driving and lost brakes. I had to step on the pedal very hard to avoid a collision. Check engine light C1391 came on

Brake system failure. Traction control light, brake light, abs light, and brake system warning light all lit up on dash. The regenerative braking is no longer working or charging battery. Obvious loss of stopping power. Does not feel safe to drive at all. Toyota wants $3,000-$4,000 for the repair. Toyota should be held liable for these failures causing crashes and potential fatalities. This should already be a recall.

Check hybrid system. Stop the vehicle in a safe place. About 90,000 miles 2013 Prius bought brand new and regular all dealer maintenance completed. Lost power on the road and very slow pickup. Not drivable and very unsafe car. Thanks.

Factual Background: I purchased the vehicle on May 2, 2023, with approximately 61,000 miles on the odometer. On October 22, 2023, the vehicle displayed Diagnostic Trouble Code (DTC) 1391, which is a known issue with Toyota Prius vehicles. Currently my vehicle currently has approximately 86,000 miles on the odometer. I first contacted Toyota on October 27, 2023, and spoke to Tier 1, Tier 2, and ultimately to a Tier 3 support representative. I was told that I could not escalate further, but that a supervisor would do a one business day call back. On October 30, 2023, I received a call back from a supervisor who escalated my case to the Executive Office. On October 31, 2023, I received a call from the Executive Office and asked for their address in order to file a formal complaint. On that very same day, I went to Peterson Toyota to have them confirm DTC 1391, which they did and my visit and paperwork is recorded within your internal system via Toyota Information System (1TIS) per the dealership. I am requesting that Toyota fix the known and now verified defective brake booster and brake booster pump in my vehicle at no cost to me, the consumer, pursuant to the Magnuson-Moss Warranty Act and implied warranty of Toyota’s products. Again all of the details regarding my vehicle and its history are found on Toyota Information System (TIS). There have been several complaints about this known issue and an investigation needs to be reopened regarding this ongoing issue. Several class a

What component or system failed or malfunctioned, and is it available for inspection upon request? Brake Booster and Brake Booster Pump Assembly have failed. Part are available for inspection. How was your safety or the safety of others put at risk? Had trouble stopping on the highway and at intersections. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes 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. Problem happened before warning lights appeared. Later, problem was verified with error codes, dash lights, and sensation of brake action.

Brake booster defect caused ABS and brake light went on, thus we lost ABS while driving. Initially we heard noises while breaking in April 2023, told to change break pads. We went in to Toyota dealer again in Oct 2023, and diagnosed with brake booster problem, leaking gas inside. Toyota knew that its brake booster has a defect in design and has customer support program as a post failure solution vs recalls as a preventative measure. We were never informed about this customer support program regarding defect in brake booster. Toyota declined to repair saying my car already missed the time window (10 years since first use). Toyota should recall brake booster assemblies for Prius 2010-2015. In my case, due to delay in diagnosing this serious problem, I was put on a serious financial burden to pay for this repair ($2800 quoted by Toyota dealer). I was also put on a life threatening risk of driving a malfunctioning car for a long time without being informed. Since the beginning of this incidence, I’ve called Toyota four times and Toyota acknowledged that they did not inform me and Toyota dealer failed to make a proper diagnosis on time to repair.

To whom may be concerned, The car I own is Toyota Prius 2013, it has the brake issue nearly a year: I can hear the brake booster pump works every 8 seconds, and the worse thing is the car is jump and has a longer brake distance when I step on the brake paddle. I even nearly had a incident at the intersection because the brake lag. I know Toyota has customer support program ZJB, and I also brought my car to Toyota Dealer. But they say they can replicate the issue. But according to the program, it must be some light on to be qualified. So now I have to take care of over $3000 bill by myself, otherwise I have to take a risk to drive my car with the brake issue. I searched online, there are a lot of customers have the similar issues like me. So Toyota has already known this issue, but why they just still wanna those cars running on the road, brake system is the most important part, it's Disregarding human life. Thanks for your time.

The brake actuator keeps buzzing every 3 seconds or so the entire time the car is on and even after I turn the car off and get out. The brakes make a wierd burping noise and the pedal depresses with each noise if I am stopped at a red light or stop sign with my foot on the brakes. All of the brake, abs, and traction control lights lit up. The regenerative braking is no longer working.

I was driving around 65 miles per hour on the highway, when I suddenly feel my brake were not working properly. Brake light, abs and traction light were shown at the same time. I almost felt like it was kind of break failure. Break would only work if i push all the way to the floor.

When the car was being driven on a surface road, the ABS, Brake and Traction lights came on. The brakes became stiff and hard to press. Braking was also slow. Car was traveling at less than 30 mph at that time When taken to the mechanic shop, and running diagnosis, the code came back to be C1391. The car has 113000 miles and purchased in July 2013.

The contact owns a 2013 Toyota Prius. The contact stated that while driving at an undisclosed speed, he depressed the brake and heard an unusual sound, and the brakes was inoperable. The contact stated he was able to slow the vehicle down and stop by continuing to depress the brake. The contact stated that when the failure occurred, the ABS system, brake system, traction control, and an unknown warning light was illuminated. The contact stated that the failure had been reoccurring for a year. The vehicle was taken to the dealer, where it was diagnosed with brake booster failure, and the dealer provided the contact with the phone number for the Manufacturer. The vehicle was not repaired. The manufacturer was made aware of the failure, and the manufacturer informed the contact that the Extended Warranty had expired on the ABS/Brake Booster. The failure mileage was approximately 175,000.

The contact owns a 2013 Toyota Prius. The contact stated that while his wife was driving at 35 MPH, when the contact's wife depressed the brake pedal, the brakes were inoperable and inadvertently all the warning lights illuminated on the control; however, the wife then let off the brake pedal and then depressed the brake pedal again and was able to stop the vehicle. The contact stated that the wife was able to safely drive the vehicle to their residence. The vehicle was taken to an independent mechanic, where it was diagnosed as having an ABS control module failure and needed to be replaced; however, the vehicle was not repaired. The manufacturer was made aware of the failure; a case was filed, but the manufacturer provided no assistance. The failure mileage was approximately 93,000.

"Cooling Performance of the Hybrid Battery is Low" warning light turns on every 4-5 months on my 2013 Toyota Prius. Apparently, Toyota issued a bulletin to Toyota Service Departments re: Engine/Hybrid System Section Hybrid/Battery Control System Market USA. This info was never disclosed and is costly to repair every 4-5 months due to excessive buildup of dust, lint, or debris in the HV battery intake filter or cooling fan. When it first went off in June 2022 my vehicle was still under warranty up to the two additional repairs in December 2022 and May 2023 (for which the Toyota Dealership repair department didn't provide me a ticket either time but made the repair), and again now (August 2023). This is an issue that could cause the battery to fail while driving. Additionally, this issue is highly inconvenient, expensive and highly concerning. This ongoing issue affects the safety and value of my car if this issue must be repaired every 4-5 months or "every 5,000 miles). This information was never made public to Prius owners I don't believe as I never received notice. I would've sold my car sooner had i known. Here is the Toyota DOcument I received on 8.21.23 from Marina Del Rey Toyota T-SB-0062-20 dated June 18, 2020

Back in May 2022, my Toyota Prius experienced issues with the braking system. I lost braking power while driving, the brake experienced a loss of power and felt very squishy to press. I had my car towed to a nearby auto shop who examined the vehicle but could not resolve the issue and recommended I take the car to Toyota. This third party auto shop reset the computer diagnostic system and cleared the error codes. When I towed the car to Toyota, the braking issue had miraculously resolved - but without the active error codes - Toyota refused to make the extended warranty repairs to the braking system that are a widespread and known issue. I continued driving the car without issue until 8/13/23 where the brake lights went on while driving and the same squishy brake issue occurred again. Toyota looked into it and determined it was related to the extended warranty braking issue, but my cars extended warranty ended on 6/29/23 - just over 6 weeks ago. Toyota refused to honor the extended warranty even though the issue first occurred in May 2022. They estimated the repair would cost $3000. I would like to have Toyota honor their agreement to extend the warranties of this braking issue.

Brake Booster Pump failed on August 5, 2023 in parking lot, as found by dealership in Marion, IL. ABS, Brake, and Traction lights were on. Vehicle has been properly maintained at dealership. Before that, the brake was making weird noises when depressed. When braking, it tends to lunge forward before slowing down. Dealer deemed vehicle not safe to drive. They showed me the primary and secondary warranty internal documents, up to 150K. My vehicle is at 150400. How could that 400 miles make any difference? But Toyota refused to cover the cost of repair at over $3000. It is clear Toyota and dealership know all along that there is an ongoing problem with their braking system. I am glad this did not happen on a highway. But other owners must be made aware of this ongoing safety issue. Something must be done to have this recalled. Many thanks for your inquiry and oversight of the issue.

Have an issue with the Prius having the error code C1391. The dealership refuses to fix the issue since it's unsafe to drive with the brake failing. Need to replace the Brake Power booster and ABS Pump/ Motor; the total cost to get all this is quoted by the dealer as $3300

Brakes are failing intermittently . There was a recall but they say we missed the deadline.Brake booster is obviously defective makes noises constantly.

The brakes on my 2013 Toyota Prius suddenly quit working normally, requiring significantly more force to stop. The car has been inspected by the dealer, who pointed it to what is apparently a common problem with the car -- failure of the brake booster/master cylinder assembly and the brake booster pump assembly. Half of the dashboard lit up when the problem occurred. No warning before.

The contact owns a 2013 Toyota Prius. The contact stated that while attempting to shift to drive(D), the transmission failed to shift as needed. The vehicle was towed to the dealer, who informed the contact that a hose had detached from the valve. The manufacturer was not made aware of the failure. The failure mileage was 167,000.

I drove myself and two neighbors to a restaurant for dinner when my traction light came on momentarily but did not stay on. We had dinner and when I went to back out of the parking stall, I felt like I did not have brakes. Since it was approximately 9 pm and I was no where near a service station, I drove very slowly because I was unsure I could get the car to stop. The traction light, the brake and ABS lights were on, as well as a loud beeping alarm. I drove in the right hand lane so I could pull off the road if I could not get the car to stop. I managed to get us home and Toyota Dealer was called the next morning. They towed the car to Dealer who sold the car to us in 2015, and where it was serviced on a rigid schedule. We had an extended warranty even after it passed the 100,00 mile mark. We bought an extended warranty beyond the original warranty but were upset to find that it did not cover the brakes! It cost $2654.00 to replace the ABS booster and brake cylinder. When I asked the Dealer to adjust our costs as brake failure was the most reported complaint on the 2013 Prius, I was told there was a 10 year /or 150,00 mile rebate program that had expired that started in 2010, but since we had not had any reported problems during the time, there was nothing they could do to help. I asked why they had never sent us a letter knowing there was a possible brake program, and was told ALL 2013 Prius owners were felt to be affected. Our Prius now has 154,000 miles on it. I explained

Hybrid battery overheats after an hour of driving at high speeds. Car battery shuts down and becomes immobile.

Approaching a red light brake failed to stop the car. I lost pressure on the brake pedal. No body was hurt. Suddenly all brake, abs and traction control lights came on at once. Toyota dealer told me i needed to replace the brake booster pump and that it was common on those cars

While driving suddenly the traction control light, the ABS light, the Brake light, and the Master warning light went on. I was able to pull off the road and stop by exerting an abnormal amount of pressure on my brakes. The vehicle was towed to the dealer where it showed code C1391. Toyota service bulletin T-SB-0024-19 addresses this saying it is caused by an internal brake fluid leak inside the brake booster assembly with master cylinder. Toyota is aware of the problem and has redesigned the parts. This is a dangerous problem with 2011-2015 Prius vehicles.

Previous models (2010) had a recall on the breaks system not this VIN number. ABS Actuator is malfunctioning, is the same system as 2010 that had a recall on it. I have two kids in the car when it stopped working without warning. A safety recall must take effect, my car only has 82000 miles on it.
