THE VEHICLE WAS TRAVELING OVER 60 MPH WHEN THE ABS, BRAKE AND TRACTION LIGHTS CAME ON AND THE BRAKE BECAME IMMEDIATELY SPONGY AND I HAD TO DEPRESSED EVEN HARDER (PAST THE FOAMINESS) TO REDUCE SPEED. A MOTOR COULD BE HEARD TRYING TO TURN OVER ON THE BRAKE SYSTEM. THE CAR SPEED WAS REDUCED TO 25-30 MPH ON THE HIGHWAY BUT THE SPONGY BRAKES CONTINUED. WITHIN 5 MIN I PULLED OFF THE HIGHWAY AND INTO A PARKING LOT. PARKED THE CAR, TURNED IT OFF AND ON TO SEE IF THAT WOULD REMEDY THE SITUATION AND NOTHING CHANGED. I THEN CALLED THE TOYOTA DEALERSHIP'S SERVICE DEPARTMENT TO BOOK AN IMMEDIATE APPOINTMENT AND ARRIVED AT THE DEALERSHIP APPROXIMATELY 40 MINUTES LATER. THE CAR WAS LOOKED AT AND I WAS TOLD THAT THE BRAKE ACTUATOR WAS THE ISSUE AND THAT THEY WOULD LIKE TO CONTACT TOYOTA TO SEE IF THIS WAS IN WARRANTY OR PART OF THE RECALL. I WAS TOLD THE NEXT DAY THAT THE COST OF INSTALLATION AND PARTS WOULD BE AT LEAST $4,000 AND THAT I WOULD NEED TO PAY THE FULL AMOUNT AS TOYOTA WAS TAKING NO RESPONSIBILITY. I CALLED THE TOYOTA CUSTOMER SERVICE LINE, EXPLAINED MY SITUATION AND WAS TOLD THE SAME THING AS I WAS TOLD AT THE DEALERSHIP. I FEEL THAT THIS BRAKE ACTUATOR (ITS PARTS, ITS COMPOSITION AND/OR ITS INSTALLATION) IS A SYSTEMIC ISSUE WITH TOYOTA PRODUCTS AND A KNOWN ISSUE WITH TOYOTA PRIUS' IN 2009 AND 2010. TANGENTIAL TO THIS ISSUE, MY FATHER OWNS A TOYOTA CAR AS WELL AND HAS ALSO HAD TO HAVE HIS ACTUATOR REPLACED THIS YEAR. TOYOTA SHOULD BE HELD RESPONSIBLE FOR ALL FAULTY PARTS AND INSTALLATION AND PURCHASE OF NEW PARTS. MY MAINTENANCE RECORD IS EXEMPLARY AND MY DRIVING RECORD IS AS WELL SO THIS IS NOT REGULAR WEAR AND TEAR IN MY OPINION.

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.

DP22005 · Pedestrian Alert Sounds
Opened Jan 27, 2023 · Closed Aug 7, 2023
Status: closed (inferred from source dates) · Electrical System:propulsion System
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.

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.
