I WAS DRIVING DOWN A CITY ROAD AT 25-30 MPH AT DUSK (5:15PM), AND WITH MY HEADLIGHTS ON. THE FIRST INDICATION OF A PROBLEM WAS THE SMELL OF BURNING RUBBER WHEN I TURNED ON THE HEATER. ASSUMING THE PROBLEM WAS WITH ANOTHER VEHICLE AHEAD OF ME, I TURNED OFF THE HEATER AND KEPT DRIVING. A MILE LATER, AS I WAS NEARING MY DESTINATION, I NOTICED SEVERAL WARNING LIGHTS TURN ON (SKID LIGHT AND EXCLAMATION MARK LIGHT) AND THE STEERING BECAME LESS RESPONSIVE. I THEN SAW SMOKE EMITTING FROM UNDER MY HOOD. A FEW SECONDS LATER, THE FRONT PASSENGER-SIDE CORNER OF THE CAR BURST INTO FLAMES. I MANAGED TO PULL OVER, WOKE UP MY TWO YOUNG CHILDREN FROM THEIR CAR SEATS, AND GOT EVERYONE OUT. WITHIN A MINUTE, THE ENTIRE HOOD WAS ABLAZE. GIVEN WHERE THE FIRE STARTED, I SUSPECT THE HEADLIGHT. I REPLACED IT THE DAY BEFORE. THE LIGHT SEEMED TO WORK FINE FOR 1 DAY, BUT IT IS SUSPICIOUS THAT IS ALSO THE AREA WHERE THE FIRE STARTED.

WHILE DRIVING ON A SIDE ROAD ON 9/26/2018 I RECEIVED AN ALERT MESSAGE THAT SAID "CHECK HYBRID SYSTEM. STOP THE VEHICLE IN A SAFE PLACE." I PULLED THE VEHICLE OVER AND SHUT IT DOWN. THE VEHICLE WOULD NOT START FOR A MINUTE BUT THEN STARTED AGAIN. I CALLED THE TOYOTA DEALERSHIP WHERE I GET MY CAR SERVICED AND I ASKED THEM IF IT IS OKAY FOR ME TO DRIVE IT HOME SINCE I WAS 110 MILES AWAY. THEY TOLD ME IT WAS OKAY TO DRIVE AND I TOOK THE CAR TO THEM TO GET IT CHECKED OUT UPON GETTING BACK IN TOWN. THEY CONFIRMED THAT THE WARNING HAD COME ON, HOWEVER COULD NOT FIND ANYTHING TO FIX IT. SO THEY RESET THE ERROR MESSAGE AND RETURNED THE CAR TO ME. I AM AFRAID TO DRIVE THE CAR ON THE ROAD WITHOUT A FIX SINCE IT COULD STOP AT A HIGH SPEED AND CAUSE ME TO BE IN A CRASH. I AM SURPRISED HOW DOES TOYOTA HAVE A PROTOCOL TO LET USERS DRIVE A FAULTY CAR ON THE ROAD?

NO CLOUDS OF SMOKE OUT OF THE EXHAUST. THE OIL USAGE SLOWED DOWN, WHEN I TRIED USING CASTRIL FULL SYNTHETIC OIL--AT THE SUGGESTION OF A NEIGHBOR OF MINE, INSTEAD OF THE TOYOTA DEALER OIL AND MOBIL 1. IT IS A CONCERN, THAT THE EXHAUST SYSTEM MIGHT BE PLUGGING UP--DUE TO THIS OIL USE ISSUE. I HAVE AN EXTENDED WARRANTY TO 200,000. THE WARRANTY COMPANY TOLD ME TODAY, THAT, THEY WILL ONLY COVER INTERNAL ENGINE PART BREAKAGE, OR WHATEVER MY FACTORY WARRANTY WAS. THEY WILL NOT COVER THE CAUSE OF THE OIL USE, AND THEY WILL NOT COVER DAMAGE CAUSED BY LACK OF OIL. SO, I WAS TOLD, TO MAKE SURE I KEEP IT FULL OF OIL. TOYOTA SHOULD CONSIDER HOW THIS WILL AFFECT THEIR FUTURE BUSINESS. A BIG SALES POINT TO THE PRIUS IS, THAT, IT SHOULD LAST A REALLY LONG TIME. IT MAY LAST A LONG TIME, YET. I'LL KEEP ADDING OIL AND WE SHALL SEE. IN THE MEAN TIME, I PLAN TO GET A ROAD SIDE ASSISTANCE PACKAGE THAT INCLUDES TOWING....

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.
DP19004 · Brake Actuator Valve Wear
Opened Sep 30, 2019 · Closed Jan 21, 2021
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.
