I was loving my Prius until yesterday June 9, 2021 when I took it to Toyota of Riverhead, NY to have my Hazard lights checked because they would not shut off. I was told that the technician found ABS actuator shorting out causing the hazards to not go off. The replacement would be $2664. I had the fuse removed because it was causing my battery to die with the hazard lights being on. I was also advised by Tonianne Rempel (service advisor) that Toyota was familiar with this problem with 2013 Prius. I have a problem with Toyota knowing that there is a problem with the hazards for this is potentially dangerous for it makes your battery die and leaving the owner stranded. This should have been a recall. I had removed the fuse so now I have no hazards or directionals leaving me to use hand signals. Which is extremely dangerous for other drivers do not look for driver using hand signals. This embarrassing for Toyota drivers seeing that somebody driving a Toyota is using hand signals because the directionals don’t function. Toyota should have done a recall knowing that this hazardous situation exists. I am asking Toyota to pay for this repair. I do not have $2664 to repair this hazardous situation that should have been addressed by Toyota and leaving me in a very dangerous situation without hazards or directionals.

A WEEK AFTER THE SYSTEM UPDATE THE SAME ISSUE AROSE AND THEY REFUSED TO REPLACE THE INVERTOR WHICH DRAINED THE HYBRID BATTERY AND RUINED IT ALSO . THIS EFFECTS THE DRIVING ABILITY AND CAUSES THE CAR TO SHUT DOWN THE LIGHTS TO NOT WORK . IT CAN STALE AT ANY GIVEN TIME AND WILL NOT HAVE POWER TO CONTINUE

WHILE DRIVING OUR 2013 PRIUS ON A 5 FIVE-LANE HIGHWAY 2-10-20, OUR PRIUS GOES INTO LIMP HOME MODE ALL THE SUDDEN AND SLOWS THE CAR DOWN SIGNIFICANTLY WHILE DRIVING AT HIGHWAY SPEED. THIS OCCURRED AT THE SAME TIME AS I WAS PASSING A CAR TO EXIT THE HIGHWAY, ALSO WITH ANOTHER CAR CLOSE AT THE REAR CLEARLY INTENDING TO GET AHEAD OF ME AFTER I HAD PASSED THE OTHER CAR. I UNEXPECTEDLY REALIZED THAT I HAD NO ACCELERATION AND THAT THE ALL THE DASH LIGHTS HAD COME ON. I WAS VERY FORTUNATELY TO BE ABLE TO MANEUVER ACROSS THE DRIVING LANES TO THE HIGHWAY EXIT WITHOUT BEING HIT AS MY SPEED GO DOWN. THE SITUATION WAS EXTREMELY HAZARDOUS. TOOK THE CAR TO THE TOYOTA DEALERSHIP THE NEXT DAY ON 2-11-20 AND THE TECH DISCOVERED THE CAR WENT INTO THE LIMP HOME MODE BECAUSE OF A CATASTROPHE INVERTER FAILURE. WE DID RECEIVE THE UPDATED SOFTWARE FROM THE RECALL IN 2014, YET THE INVERTER STILL FAILED. THE INVERTER WAS REPAIRED BY THE TOYOTA DEALERSHIP 100% UNDER WARRANTY.

3Jun 24, 2020
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.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2014 Toyota Prius and 2012-2014 Toyota Prius V vehicles. 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: If the hybrid system shuts down unexpectedly, it can increase the risk of a crash.
Remedy: Toyota will notify owners, and dealers will update the software for the motor/generator control electronic control unit (ECU) and the hybrid control ECU as necessary, free of charge.

Feb 12, 2014
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 recall began on March 21, 2014. Owners may contact Toyota at 1-800-331-4331.

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.
