BEING TOLD $2700 REPAIR NOT COVERED BY WARRANTY THAT I NEED TO CLAIM ON MY CAR COMPREHENSIVE COVERAGE. CONCERNED THAT IF IT IS RODENT DAMAGE, IS IT DUE TO MATERIALS USED THAT ARE ATTRACTIVE TO RODENTS (WOULDN'T THIS BE A PROBLEM FOR ALL PRIUS OWNERS), ESPECIALLY IN AREAS THAT HAVE MORE OF A VISIBLE SMALL RODENT POPULATION? ALSO, DON'T KNOW HOW TO PROVE IT WAS MANUFACTURER OR DESIGN DEFECT - ASKING DEALER TO DOCUMENT HOW THEY CAME TO BELIEVE IT IS A RODENT PROBLEM.

WE HAVE OWNED A 2006 PRIUS AND ASKED IF THEY MIGHT HAVE A NEW MODEL TO RENT FOR COMPARISON ON OUR PART, WHICH THEY DID, HOWEVER IT TURNED OUT TO BE A PRIUS C, WHICH WAS NOT AT ALL LIKE OUR PRIUS. THE TRAFFIC ON THE FREEWAY WAS STOP AND GO SLOW ON A MULTI LANE FREEWAY AND WERE ON AN INNER LANE. ( I - 405 NORTH BOUND ) AS I ROLLED UP TO WHAT MIGHT HAVE BEEN A STOPPING SITUATION THE TRAFFIC STARTED TO MOVE FORWARD, AND AS I STEPPED ON THE PEDAL TO MOVE FORWARD, I NOTICED THAT NOTHING WAS HAPPENING AND THE CAR SOON CAME TO A COMPLETE STOP. THE CAR WAS ABSENT AND VISIBLE POWER, NO VISUAL INFORMATION ON THE MPH SCREEN, THE EMERGENCY LIGHT WOULD NOT WORK, I WAS NERVOUS AND SCARED AND EVERYTHING HAD GONE DARK, I DID NOT WHAT TO DO, I TRIED TO MOVE THE KEY POSITION THE CARS BEHIND ME STARTED TO HONK, AND THEY WERE ALSO TRYING TO GET AROUND ME, JUST AS I WAS STARTING TO CALL 911 FOR SOME HELP THE CAR POWERED BACK UP WITH A MESSAGE TO PUT THE CAR IN PARK AND START THE MOTOR I MOVED OUT OF THE SITUATION AND GOT OFF THE FREEWAY AND TOOK BACKROADS TO REACH THE MOTEL, WITH THE INTENT TO NEVER DRIVE THIS CAR AGAIN, THE NEXT AM I CALLED HERTZ AND THEY MADE ARRANGEMENTS TO TRADE THE CAR OUT AT OUR MOTEL, WHICH THEY DID. THE TOW TRUCK DRIVER INDICATED THAT THE PROBLEM ON THIS SPECIFIC CAR WAS CAUSED BY ITS SOFTWARE AND HE WAS AWARE OF OTHER DRIVERS FACING THE SAME SITUATION, BUT I SHOULD COUNT MY BLESSING THAT I WAS NOT INVOLVED IN A MAJOR ACCIDENT I DO NOT THINK THIS CAR SHOULD EVER BE ALLOWED ON OUR ROADS JUST BASED ON THIS EXPERIENCE.

SHORTLY AFTER PURCHASING MY 2014 TOYOTA PRIUS IN JUNE 2014, I STARTED NOTICING A MOLDY SMELL COMING FROM THE AIR CONDITIONER. THE HOTTER OUTSIDE IT GOT, THE WORSE THE SMELL INSIDE GOT. I TOOK THE CAR TO THE DEALER TO DISCUSS THE PROBLEM WITH THEM. THEY INFORMED ME THAT TOYOTA SAYS THIS IS AN "ENVIRONMENTAL ISSUE" AND CAN HAPPEN IN NEW CARS AND IS THEREFORE NOT WARRANTIED. THE SERVICE MANAGER INSTALLED A CHARCOAL AIR FILTER IN THE CABIN AIR FILTER AND SAID THAT IT WOULD HELP ELIMINATE THE ODOR. IT DID NOT. IN FACT, THE CHARCOAL AIR FILTER REDUCED THE AIR FLOW INTO THE CABIN WHICH CAUSED THE AC TO NOT COOL. I HAD THE SERVICE DEPARTMENT REPLACE THE CHARCOAL WITH AN ORIGINAL AIR FILTER IN SEPTEMBER AFTER COMPLAINING THAT THE AC WASN'T COOL. THE SMELL IN THE AC PERSISTS. IT'S NOT JUST A BIT WHEN THE CAR IS TURNED ON. NO MATTER WHAT SETTING I PUT THE AC ON, IT DOES NOT HELP (FRESH AIR OR RECIRC). WHEN IT RAINS OR WHEN IT IS REALLY HUMID OUTSIDE, THE CAR SMELLS LIKE A SWAMP (EVEN BEFORE IT IS TURNED ON). THERE IS ALSO HUMIDITY INSIDE THE CAR WHEN OPENING THE DOOR. I'VE ASKED MULTIPLE TIMES TO HAVE THE EVAPORATOR REPLACED BECAUSE I FEAR THAT IT IS NOT DRAINING AND CAUSING MOLD AND MILDEW TO FORM. BREATHING IN THE MOLD IS A SERIOUS HEALTH CONCERN AND TOYOTA WILL NOT AGREE TO ANY KIND OF FIX. I'M ALSO HAVING OTHER VARIOUS HVAC PROBLEMS SUCH AS CONTINUOUSLY FOGGING WINDOWS AND A DRAFT FROM THE DRIVERS SIDE DOOR. THE CAR DOES NOT HOLD HEAT AND IS VERY COLD DURING THE WINTER MONTHS. *TR

Oct 4, 2018

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

14V053000 · Electrical System:software; Hybrid Propulsion System: Inverter

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.
