IN THE PAST YEAR I HAVE HAD 2 OCCURRENCES OF UNINTENDED ACCELERATION. THE FIRST IN FEBRUARY OF 2016. I WAS EXITING A PARKING RAMP UP HILL AND STEPPING ON THE ACCELERATOR. I WAS DRIVING STRAIGHT THEN TURNING TO THE LEFT (90 DEGREE TURN). WHEN I TOOK MY FOOT OFF THE ACCELERATOR, THE CAR CONTINUED TO ACCELERATE AND I WAS UNABLE TO GET IT SLOWED/STOPPED FOR ABOUT A BLOCK EVEN THOUGH I WAS APPLYING HEAVY BRAKE PRESSURE. THE CAR WAS REVVING AGAINST THE BRAKE PRESSURE. NO DAMAGE OR INJURIES OCCURRED. I TOOK THE CAR TO THE DEALERSHIP WHERE I PURCHASED IT (PURCHASE DATE 8/3/13). THEY CHECKED THE CAR OVER AND FOUND NO APPARENT CAUSE FOR THE ACCELERATION. I TOOK THE CAR HOME, AND IT DROVE NORMALLY UNTIL 11/26/16. ON THAT DATE I WAS DRIVING VERY SLOWLY IN A FLAT PARKING LOT, AND THE CAR BEGAN ACCELERATING WITHOUT MY PUSHING THE GAS PEDAL. I WAS DRIVING STRAIGHT AND THEN TURNING TO THE RIGHT (90 DEGREE. I GOT THE CAR STOPPED IN A FEW FEET BY PRESSING EXTREMELY HARD ON THE BRAKE. MY CAR DID NOT HIT ANYTHING. TECHNICIANS FROM THE DEALERSHIP HAVE NOT BEEN ABLE TO FIND A CAUSE AND I HAVE NOT BEEN ABLE TO GET PAST TOYOTA'S CUSTOMER SERVICE DEPARTMENT TO ESCALATE THE ISSUE FOR MORE DETAILED DIAGNOSTICS. I HAVE ATTACHED THE TIMELINE OF TRYING TO GET THE CAR DIAGNOSED AND THE ISSUE ESCALATED AS WELL AS WHY I DON'T THINK USER ERROR IS A FACTOR. *TR

I WAS IN A PARKING STRUCTURE GOING APPROXIMATELY 15 MPH WHEN I REMOVED MY FOOT FROM THE ACCELERATOR TO PRESS THE BRAKE. BEFORE I COULD GET MY FOOT TO THE BRAKE, THE CAR QUICKLY ACCELERATED. IT TOOK AT LEAST TWO ATTEMPTS AT PUSHING THE BRAKE PEDDLE BEFORE THE CAR CAME TO A STOP. AND, TO BE HONEST, THE GUARDRAIL THE CAR HIT HELPED ACTUALLY STOP THE VEHICLE. IT WAS TOTALLY UNEXPECTED AND EXTREMELY SCARY. IN HINDSIGHT, I SHOULD HAVE SUSPECTED THAT THERE MAY BE A PROBLEM WHEN I NOTICED THAT SOMETIMES WHEN APPLYING THE BRAKES TO COME TO A STOP THERE WOULD BE A FEELING OF THE BRAKES SLIPPING AND THE CAR LURCHING FORWARD A BIT. THE DEALERSHIP HAD THE CAR TOWED IN TO GET CHECKED OUT, AND I HAVE BEEN TOLD THAT THEY WILL NOTIFY TOYOTA. IN THE MEANTIME I AM CONCERNED ABOUT THE SAFETY OF THIS CAR!

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.

This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.

Remedy: Southeast Toyota will notify owners, and dealers will test the sensitivity of the occupant detection sensors, and recalibrate them as necessary. The recall began on March 21, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.

ODI will review the work conducted during DP19-004 and a review of any additional related complaints and crashes via a new defect petition The petition and related materials can be reviewed at NHTSA.gov under the following ODI number:11553736.

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.

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.

PE10006 · Braking Performance, Hybrid Vehicle

Opened Feb 3, 2010 · Closed Jul 12, 2010

Status: closed (inferred from source dates) · Service Brakes, Hydraulic; Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip; Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip:control Unit/module ; Service Brakes, Hydraulic:foundation Components; Service Brakes, Hydraulic:foundation Components:disc; Service Brakes, Hydraulic:power Assist; Service Brakes, Hydraulic:power Assist:hydraulic

The subject vehicles are the first model year of a new design generation of the Prius model line.The vehicles are powered by a hybrid drive system that uses both a regenerative braking system, which converts vehicle momentum into electrical energy to be stored in onboard batteries, and a hydraulic brake system more typical of the brake system used on non-hybrid vehicles.As is the case for other similarly designed hybrid vehicles the interaction and management of the two braking systems during ABS braking is complex and requires a sophisticated control system.In a February 9, 2010 Defect Information Report, Toyota advised the agency of its plans to conduct a safety recall to address inconsistent brake feel and increased stopping distances that may occur during braking events requiring ABS operation, such as would occur when braking on rough or low friction road surfaces.Toyota will reprogram the ABS control unit with improved software that addresses this condition.Based on Toyota's action the investigation is closed. ODI will continue to monitor the subject vehicles' performance and will take further action as future circumstances dictate.
