Break booster issue. Car only has 63,465 miles. Toyota has received reports about certain internal malfunctions of the brake booster. Problem is, not many have had luck getting the part covered because it's likely that the problem does not commonly present itself until after the warranty expires.

The ABS system has failed, and I have to pony up $3000 + for repair, since the warranty extension from Toyota has expired - 10 years since first use (even though I have only had it for 5 years). I have less than 150,000 miles on this car, which is the the other parameter for service coverage for this problem. Toyota knows these parts fail, and they extended the warranty, BUT there is no recourse if your car is over the 10 year limit, even if under the mileage limit. it is a safety issue and should be addressed no matter the age of the car. I can't afford the cost of repair and so will gamble on not needing to use the antilock brakes.

6/12/25 I'm driving my 2013 Prius w 123K m through a construction zone. The road became bumpy and when I depressed the brake nothing happened. Thinking I must have hit air or be imagining things I tried the other pedal. The acceleration re-oriented me to the fact that my brakes were non-existent. Many lights I've never seen illuminated on the dash as I looked into my mothers eyes to say we had no brakes. I was somehow able to pull safely. After the initial loss of braking I discovered I had a small amount of stop if I put the pedal on the floor. The closest local shop thought most of the internal braking system related to the pump and actuator would need to be replaced but requested I get an opinion from Toyota. At drop off I had requested they top off the brake fluid, despite their informing me that was never necessary. Perhaps this repressurized the system because upon visiting the car all dash lights were off and the brakes felt normalish. The shop did not know why. This is my only transportation.At 9:30 in the AM 6/14/25 I proceeded to the closest Toyota dealership w the safest direct route slowly with hazard lights and lots of space from other cars. While waiting for diagnosis I discovered this exact issue was a known defect and had been the subject of a class action lawsuit and customer service bulletin of which i had no notice. Since 2022/2023 the car had been briefly and consistently losing traction over minor bumpy conditions. Without notice of the issue I had no way to know this was a precursor to Total brake failure. This car was serviced at 3 Toyota dealerships during the extended warranty authorized by the CSB. I was never apprised of the potential issue, and expressly requested a list of recalls related to my vehicle at Lumberton Toyota in 2022 which they refused to provide. I therefore googled recalls, but this issue was not a recall. I have never heard of a CSB. Two Toyota dealers quoted me the full price to replace the braking system, $3,273.94.

my 2013, Toyota Prius recently suffered a sudden hybrid system failure with DTC space P0A0F and a check hybrid system warning. This matches the symptoms described in NHTS a safety recall 20V369000. Your recall look up tool shows my Vin is not included. However, I have never received this recall repair, and my failure is identical to the documented safety issue. I am requesting help in getting Toyota to complete a goodwill repair or warranty extension review as this is clearly a safety related inverter failure for which Toyota has acknowledged responsibility and similar vehicles.

My vehicle displays the anti-skid light when brakes are applied. I also hear a chirping noise and brake pump activation noise when the vehicle's brakes are utilized and as the vehicle is stopped. Information on the internet indicates this is a serious issue with the Prius Gen III brake system, requiring replacement of the hydraulic brake booster and pump. This brake failure should not be happening, and Toyota has already identified this problem. This Prius has been trouble free up to this point and has ~185,000 miles.

Toyota defective ABS system- revised master cylinder&brake booster pump never changed by dealership except misleading inspection and breach of recall in 2020. The incident happened last year in Sep 2024 dangerous on hwy or freeway. Thank got I was on the side street with beeping vehicle and codes on the dashboard, barely with serious risk went back home! As a defective parts they should be replaced for free or customer should received reimbursement! A professional dealer who performs ONLY AN INSPECTION for a “recall” in 2020 should replace the factory-damaged part and not brazenly wait for the codes to appear on the dashboard, depriving the customer of free replacement of the factory-defective ABS system. "the complaint was originally filed over the Toyota hybrid system problems in Feb. 2020, presenting claims on behalf of owners of certain 2010 through 2015 Toyota Prius and Prius PHV, 2012 through 2015 Toyota Prius V, 2012 -2014 Toyota Camry Hybrid and Toyota Avalon Hybrid vehicles that contain the defective braking system" ... This complaint accuses Toyota of placing PROFITS before the lives and safety of hundreds of thousands of drivers and passengers whose brakes are defective, but must wait for the potentially life-threatening brake booster defect to occur before the manufacturer will address it. The lawsuit ; ;"presents claims of breach of warranties, false advertisement, illegal sales practices, fraudulent concealment, unfair and deceptive trade practices, unjust enrichment and various other allegations on behalf of hundreds of thousands of impacted vehicle owners across the nation".

Consequence & remedy
Consequence: An unexpected hybrid power system shut down may increase the risk of a crash.
Remedy: Toyota will notify owners, and dealers will perform a software update for the hybrid system. If the vehicle has experienced an inverter failure with certain hybrid system faults related to this condition, the inverter assembly will be repaired or replaced, prior to software update. All repairs will be performed free of charge. This recall began July 24, 2020. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is 20TB10 / 20TA10.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

On September 19, 2019, the Office of Defects Investigation (ODI) received a defect petition from Mr. Roger Hogan requesting that the Agency investigate and recall certain Toyota Prius, Prius PHV, Camry Hybrid and Avalon Hybrid vehicles for a brake actuator valve wear condition covered under Toyota Customer Support Programs ZJB and ZKK (subject CSP?s). In support of his request, the petitioner identified 117 NHTSA complaints allegedly related to the subject CSP condition, including 60 reporting crashes. On September 30, 2019, ODI opened Defect Petition DP19-004 to evaluate the petitioner?s request for an investigation. In August 2020, the petitioner notified the Agency that he was withdrawing his petition. Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary.NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Because the petitioner has with withdrawn the petition, the petition is denied as moot. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency notes that it is not required to receive a defect petition prior to opening a defect investigation and will take further action if warranted by future circumstances.
