On 2/14/2025 I brought my 2013 prius into a third party mechanic because all the brake warning lights came on while driving. After inspection the mechanic informed me that there was a vehicle service bulletin about the brake booster and brake booster system that Toyota sent out in September 2020. It states that models made between 2012-2014 may exhibit a condition where the brake ABS and/or on track lights are on and it is caused by a small internal brake fluid leak inside the brake booster assembly with master cylinder. Toyota placed an extended warranty on the part. They state that if the vehicle had the abs light come on for this reason they would fix it if and only if it fell within 150,000 miles or ten years from the first driven part. I have been told if the issue is not addressed it could caused brake failure, the repair is upwards of $3000. I have contacted Toyota to open a case and will be taking the car to a Toyota dealership but Toyota is not taking any responsibility for the faulty part even when they know it is an issue because they say it fell outside of the extended warranty. I need Toyota to be held accountable and for not addressing a known issue with the their product. This is not an issue with wear and tear, it caused by a faulty part on their part and just because the issue became apparent after their cut off does not mean they are not liable. The car has 125,000 miles on it, I was never made aware that there was an issue with the part, received no communication until I brought it into a mechanic who researched it.

My car is at 89K total miles and last week I had three warning lights pop up on my dash (Traction control, brake, ABS) which indicates something wrong with the automatic break system. My car is under 100K miles and I purchased it used in 2016, under ten years ago, and this problem is way too early to happen in my make an model. I got a code read on the issue (C1391) which indicates that my ABS Actuator is leaking/broken, a major safety issue as it happened as I was driving. Again, this should not be typical as I only drive a few miles per day on average.

Hello, This is not only ridiculous but not unacceptable alert what Toyota did to customers under certain age of Prius 2010-15, Camry hybrid 2012-2014 and Avalon hybrid 2013-2015 They “inspected” my vehicle at the dealership in 2020 during the recall but they did not replaced defective parts (master cylinder & brake booster pump) from Japan. In September I could easily crash my vehicle. This is dangerous for customers and drivers especially in Uber & Lyft. Headquarters should be easily informed by you about it I fixed and send receipts to lovely Toyota- Idiota but they reacted with no responsibility of reimbursement. [XXX] Thanks for your attention!

I was driving on the highway. All of a sudden abs light, brake light and traction control light came up on my screen. Car lost braking efficiency and I almost crashed into the vehicle in front of me. It was within inches from crash. Found out it was the brake booster and the brake booster pump. Both these parts had been under extended warranty by Toyota unbeknownst to me. Never received any warranty letter or anything from Toyota. I contacted them but since our car has more tha 150,000 miles and over 10 years old they will not cover

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2013-2015 Prius and 2014-2017 Prius V vehicles not included in recall 18V-684. Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven.
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.

Note: The software updates in this recall are needed even if the vehicle had the software previously updated under recalls 14V-053 or 15V-449.
Toyota is recalling certain model year 2010 through 2014 Prius vehicles. In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. If this occurs, various warning lamps will be illuminated on the instrument panel and the vehicle will have reduced power allowing it to only drive a short distance.
Consequence & remedy
Consequence: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.
Remedy: Toyota will notify owners and dealers will update the software for both the motor/generator control electronic control unit (ECU) and the hybrid control ECU, free of charge. If an owner experiences a failure of the inverter before the vehicle receives updated software, the dealer will repair or replace the inverter assembly with a new one at no charge.

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.

Status: closed (inferred from source dates) · Service Brakes, Hydraulic:power Assist
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.
