I AM WRITING DUE TO HAVING HAD MY 2010 TOYOTA PRIUS SELF ACCELERATE WHILE DRIVING ON FOUR OCCASIONS. THIS BEGAN OCCURRING AFTER I TOOK MY VEHICLE TO TOYOTA OF CLERMONT, FLORIDA FOR A ROUTINE SERVICE ON 3/31/2014. WHILE THE VEHICLE WAS THERE, THE DEALERSHIP ALSO PERFORMED A RECALL ON THE VEHICLE. THIS RECALL IS REFERENCED AS: TECH(S) : 20799 RECALL EOE MOTOR GENERATOR AND POWER MANAGEMENT UPDATE PERFORM SOFTWARE UPDATE FOR MG ECU AND POWER MANAGEMENT ECU AGG09A 0.7 AS OF 8/5/2014 MY VEHICLE HAS HAD UNINTENDED ACCELERATION ON 4 OCCASIONS. IN 3 OF THE 4 I KNOW IT HAS OCCURRED AS I RELEASED THE BRAKE. THIS RELEASE IS CONFIRMED BY THE FACT THAT IT IS NECESSARY TO REAPPLY THE BRAKE TO STOP THE ACCELERATION. THE 4TH OCCURRENCE MAY ALSO HAVE OCCURRED AFTER A BRAKE RELEASE. I HAVE ATTEMPTED TO RESOLVE THIS PROBLEM VIA BOTH MY LOCAL TOYOTA DEALER AND TOYOTA CUSTOMER EXPERIENCE CENTER AT 1 800 331-4331. I AM BEING TOLD THE PROBLEM IS OPERATOR ERROR. I HAVE DONE THE RESEARCH TO SEE IF THIS IS EVEN POSSIBLE. FOR ME TO APPLY THE BRAKE AND FUEL SIMULTANEOUSLY WOULD BE BOTH EXTREMELY DIFFICULT AND VERY OBVIOUS. ADDITIONALLY IF THIS DIAGNOSIS WERE CORRECT THE VEHICLE WOULD STOP ACCELERATING WHEN THE BRAKE WAS RELEASED. IN FACT THE VEHICLE ACCELERATES WHEN THE BRAKE IS RELEASED NOT WHILE THE BRAKE IS DEPRESSED. *TR

AFTER DRIVING FOR A COMBINED TIME OF 4 HOURS IN A 5 HOUR PERIOD, MY WIFE LEFT A STORE SHE VISITED OFF ZEBULON ROAD AND I-475 NEAR MACON GA.

THE DASH INDICATORS SAID CHECK HYBRID POWER SYSTEM. THE CAR WAS TOWED TO A DEALER ROGERS TOYOTA IN MACON GA, WHERE IT NOW IS. THE DEALER SAYS THAT THE PROBLEM WAS THE ENGINE CONTROL MODULE THOUGH THE INVERTER IS BEING REPLACED UNDER AN EXISTING RECALL ISSUED LAST WEEK.

I WAS DRIVING WITH THE FLOW OF TRAFFIC (AROUND 30 MPH) ON A MAIN SURFACE STREET IN A MIDDLE LANE OF A MULTILANE STREET WHEN SUDDENLY THE ENGINE STOPPED, AND I WAS UNABLE TO MAKE THE ENGINE RESPOND. THE CAR IMMEDIATELY BEGAN TO SLOW DOWN; I COULD NOT MAKE IT ACCELERATE TO KEEP IN THE FLOW OF TRAFFIC. I MANAGED TO CAREFULLY DRIFT OVER TO THE RIGHT AND MANEUVER THROUGH AN INTERSECTION AND GLIDE TO A STOP ON THE RIGHT SIDE OF THE ROAD. I TURNED OFF THE ENGINE AND REPEATEDLY TRIED TO RESTART IT TO NO AVAIL. I CALLED FOR TOWING SERVICE AND HAD THE CAR TOWED TO MY TOYOTA DEALER, WHERE THE SERVICE PEOPLE SAID IT WAS AN "INTERNAL FAILURE" AND REPLACED THE INVERTER ASSEMBLY. WHAT HAS TERRIFIED ME IS THAT I COULD HAVE BEEN ON THE FREEWAY DRIVING AT LEAST 60 MPH, WHERE THE CONSEQUENCES WOULD BE DEVASTATING TO ME AND OTHERS. I ASKED IF TOYOTA WOULD BE REPORTING THIS TO THE NHTSA, AND THEY SAID THAT WAS AN INTERNAL DETERMINATION. I ASKED IF THIS HAD HAPPENED BEFORE TO OTHERS AND DID NOT RECEIVE A CLEAR ANSWER. *TR

ONCE I ARRIVED THE SERVICE ADVISOR INFORMED ME, THE 2010 TOYOTA PRIUS HAS TWO ACTIVE SAFETY RECALLS. I WAS NEVER NOTIFIED. THE TWO SAFETY RECALLS ARE THE HYBRID INVERTER & BRAKE BOOSTER PUMP ASSEMBLY. TODAY IS THURSDAY FEBRUARY 27TH 2014 AND THE TOYOTA DEALER HAS FAILED TO REPAIR AND RETURN MY CAR. THE TOYOTA DEALER STATED THIS IS A SAFETY RECALL, THEY NEED PERMISSION FROM TOYOTA HEADQUARTERS TO APPROVE PARTS. I PLEADED WITH THE TOYOTA DEALER TO PROVIDE ME WITH A VEHICLE, WHILE I WAIT, THEY REFUSED. *TR

WHILE CAREFULLY PARKING MY PRIUS 2010 AT A HOSPITAL IT ACCELERATED SUDDENLY AND CRASHED OVER THE CEMENT CURB. I SAY CAREFULLY BECAUSE MY PRIUS HAD DONE THIS BEFORE BUT NOT ENOUGH DAMAGE WAS DONE TO FILE WITH INSURANCE. THERE FOLLOWED ANOTHER ACCIDENT AND ANOTHER ACCIDENT. THEN THIS EVENING WHILE DRIVING INTO MY CARPORT MY PRIUS ACCELERATED AGAIN. IT THREW MY DOG THAT WAS IN THE FRONT SEAT TO THE FLOOR BUT I WAS ABLE TO AVOID CAR DAMAGE AS I WAS GOING TO STOP. I WAS BARELY MOVING, THAT IS I STILL HAD MY FOOT ON THE ACCELERATOR,MAYBE I COULD SAY COASTING, WHEN THIS ACCELERATION SUDDENLY OCCURRED. THIS WAS THE SAME TYPE ACCELERATION THAT CAUSED ALL THE PRIOR ACCIDENTS. I HAVE REPORTED THIS TO TOYOTA... AND NOW YOU. HOPEFULLY YOU WILL HELP ME. MY PRIUS IS IN THE CARPORT. IT HAS NOT BEEN MOVED. HOWEVER, IT IS MY ONLY TRANSPORTATION. MY PRIUS' LATEST HAPPENING, BEFORE THE ONE JUST STATED, THE HYBRID SYSTEM QUIT WORKING DURING RUSH HOUR TRAFFIC ON THE INTERSTATE NEAR A BUSY INTERSECTION. THIS WAS REPAIRED BEFORE TOYOTA SENT SOME ONE TO INVESTIGATE THE PRIOR ACCIDENTS. IF MORE INFORMATION IS NEEDED JUST LET ME KNOW. THIS PRIUS ALSO HAD A BATTERY REPLACED SHORTLY AFTER IT WAS PURCHASED AS A NEW VEHICLE. THIS PRIUS HAS WHEEL RIM SCRATCHES. *TR

OUR 2010 PRIUS SUFFERED A NEAR TOTAL POWER FAILURE ON 5/10/13 WHEN THE CAR SUDDENLY AND WITHOUT ANY ADVANCED WARNING, LOST POWER DECELERATING FROM ABOUT 35 MPH TO ABOUT 4 MPH IN LESS THAN 5 SECONDS. EVERY IDIOT LIGHT CAME ON AT ONCE ON THE DASH PANEL AND A "HYBRID SYSTEM FAILURE" NOTICE CAME UP ON THE ALPHANUMERIC DISPLAY. LUCKILY, I WAS ON A CITY STREET AND NOT THE HIGHWAY WHEN THIS HAPPENED. I WAS ABLE TO GET THE CAR SAFELY OFF TO THE SIDE OF THE ROAD AND CALL FOR A TOW. OUR PRIUS HAS APPROX. 44000 MILES ON IT, IS REGULARLY MAINTAINED AT THE DEALER, NOT MISTREATED IN ANY WAY AND GAVE NO ADVANCED WARNING INDICATION THAT THERE WAS ANYTHING WRONG WITH THE ELECTRICAL/PROPULSION SYSTEM. THE CAR LOST ALMOST TOTAL POWER, LIMPED ABOUT 50 FEET PAST PARKED CARS AND JUST DIED AT THE CURB AFTER I PUT IT IN PARK. IT WOULD LIGHT UP ACROSS THE DASH, BUT NEVER START THE ENGINE. WE HAVE HAD THIS CAR ABOUT 36 MONTHS. AS THIS IS MY WIFE'S CAR, I AM GREATLY WORRIED ABOUT THE SAFETY OF THE CAR AND HAVING THIS PROBLEM HAPPENING AGAIN, ESPECIALLY TO HER AT HIGH SPEED, MULTI-LANE HIGHWAY DRIVING. IT HAS BEEN REPAIRED AT A LOCAL TOYOTA DEALERSHIP. THEY INSTALLED A NEW 12V BATTERY AND EVENTUALLY THE MAIN FIX, A INVERTER/CONVERTER. THE CAR NOW RUNS LIKE DAY ONE. HOWEVER, HOW DO WE TRUST THIS CAR IN THE FUTURE IF IT DID NOT GIVE ANY WARNING OF IMMINENT PROPULSION FAILURE ? I AM GETTING NOWHERE WITH TOYOTA ABOUT THEIR PROVIDING SOME KIND OF ADVANCED WARNING TO GET THE CAR ONTO THE SHOULDER OF THE ROAD AND KEEP IT RUNNING FOR ABOUT 1 - 5 MINUTES. THANK YOU *TR

THE INCIDENT OCCURRED WHEN I ATTEMPTED TO ACCELERATE ONTO A TWO-LANE HIGHWAY. BECAUSE OF A SLOW AND SHARP U-TURN WHICH PRECEDES THE SHORT ON-RAMP, I DISABLED THE ECO MODE FOR BETTER ACCELERATION. WHEN I PRESSED DOWN ON THE GAS, THE CAR IMMEDIATELY EMITTED A LOUD SOUND, BECAME UNRESPONSIVE AND WAS UNABLE TO GAIN ADDITIONAL SPEED. EVEN SO, THERE WAS NO OTHER OPTION BUT TO MERGE ONTO THE ROADWAY WHILE DOING NO MORE THAN 30 MPH. IN THE MEANTIME, THE INSTRUMENT PANEL SHOWED A "CHECK HYBRID SYSTEM" MESSAGE ALONG WITH SEVERAL WARNING LIGHTS. I MANAGED TO AVOID ONCOMING TRAFFIC (FROM BEHIND) AND SAFELY PULLED ONTO THE GRASS. ATTEMPTS TO RESTART THE VEHICLE WERE UNSUCCESSFUL WITH THE PREVIOUS MESSAGE REAPPEARING EACH TIME. THE CAR REQUIRED A TOW TO THE NEAREST TOYOTA DEALER. I RECEIVED A CALL FROM THEM THE NEXT BUSINESS DAY, AND THEY EXPLAINED THE CAUSE TO BE A DEFECTIVE INVERTER BASED ON THE DIAGNOSTIC CODE. FORTUNATELY, THE REPAIR WILL BE COVERED UNDER TOYOTA'S HYBRID WARRANTY. IT REMAINS TO BE SEEN AND I AM HOPEFUL THIS REPAIR WILL FULLY RESOLVE THE ISSUE. *TR

This petition is based on the petitioner's direct experience and assessment that ODI closed DP19-004 because its prompting petition was withdrawn by that petitioner. 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

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.
