THE RENTED 2013 TOYOTA PRIUS WITH ONE PASSENGER AND THE DRIVER, PULLED INTO A DIAGONAL PARKING SPACE IN FRONT OF A STRIP MALL STORE. TRAVELING AT MAYBE 5 MPH TO PARK, THE CAR'S BRAKE PEDAL GAVE WAY AND HIT THE FLOOR FLAT, PROVIDING NO BRAKING AT ALL. THE CAR KEPT ROLLING TOWARD THE CORNER OF THE BRICK BUILDING. THE CAR THEN SUDDENLY SURGED AHEAD, SMASHING INTO THE CORNER OF THE ENTRY TO THE BRICK BUILDING AT SUCH A SUDDEN FORCE THAT THE DOORS TO THE BUILDING WERE WEDGED SHUT. AFTER EMERGENCY VEHICLE TOOK THE DRIVER AND PASSENGER TO THE HOSPITAL, THE POLICEMAN ON THE JOB, AS WELL AS THE WRECKER SERVICE THAT CAME TO EXTRACT THE VEHICLE, COULD NOT MOVE THE CAR BECAUSE THERE WERE NO BRAKES, AS STATED IN THE POLICE REPORT. THE WRECKER DRIVER COULD NOT LOAD THE VEHICLE TO TOW USING THE CAR'S POWER BECAUSE THERE WERE NO BRAKES. NO AIRBAGS DEPLOYED, BUT THE CONDITION OF THE CORNER SHOWS DAMAGE THAT A VEHICLE MOVING FASTER THAN 5 MPH WOULD INCUR. THE POLICEMAN CAME TO THE HOSPITAL TO INFORM THE DRIVER THAT THERE INDEED WERE NO BRAKES ON THE CAR AND THE DRIVER WAS NOT AT FAULT - THE VEHICLE'S BRAKING AND ACCELERATION SYSTEMS HAD FAILED. *TR

FIRST, UNDERSTAND THERE WAS NO ACCIDENT, NO ONE GOT HURT, AND IT DIDN'T COST ME A DIME. THE DEALER AND WARRANTY PICKED UP THE FULL TAB. ALL IT COST ME WAS A LITTLE AGGRAVATION. HOWEVER, I FEEL IT SHOULD NOT HAVE HAPPENED. IT STARTED WHEN I HAD A FLAT TIRE. I REMOVED THE FLAT AND PUT ON THE SPARE, NO PROBLEM. THE TIRE HAD A SIDEWALL PUNCTURE SO FIRST THING MONDAY I TOOK IT TO GK TIRE & AUTO FOR REPLACEMENT. THEY MOUNTED A NEW TIRE AND PUT THE SPARE BACK IN THE TRUNK. THAT IS WHERE THINGS WENT WRONG. MY PRIUS WOULD NOT START. I CALLED THE DEALER. THE DEALER SENT A TOW TRUCK AND HAULED THE PRIUS OFF. THE NEXT DAY THEY CALLED TO SAY IT WAS FIXED. THE SERVICE TICKET SAID "PULLED CODE P0A0D...CLEARED CODES, AND CHECKED SERVICE PLUG. FOUND PARTIALLY PULLED OUT." ... "INSTALLED SERVICE PLUG ALL THE WAY AND TEST DROVE VEHICLE. GOOD, DONE". BECAUSE GK TIRE HAD NO REASON TO BE ANYWHERE BUT IN THE TRUNK I ASSUME THAT IS WHERE THE 'SERVICE PLUG' IS AND THEY KNOCKED IT OUT OF PLACE WHEN THEY RE STOWED THE SPARE. MY PROBLEM IS THAT IF THE TIRE PEOPLE COULD DO THAT, THEN I MIGHT HAVE DONE THAT. AND, IF I HAD DONE THAT IT COULD HAVE BEEN IN THE MIDDLE OF NO WHERE, OR EVEN WORSE, THE CROSS BRONX EXPRESSWAY. I WOULD NOT EXPECT THAT I WOULD HAVE TO TREAT THE TIRE COMPARTMENT OF A TRUNK LIKE A FINE SWISS WATCH. IF THAT WAS THE PROBLEM, I CONSIDER IT A DESIGN DEFICIENCY. WHEN GK TIRE PUT IT ON THE LIFT? STILL A DESIGN DEFICIENCY. IT SHOULD NOT HAVE HAPPENED. *TR

Official recalls
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.
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
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. The recall began January 22, 2019. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is J0V. Note: The software updates in this recall are needed even if the vehicle had the software previously updated under recalls 14V-053 or 15V-449.
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.

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.

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.
