MY PRIUS IV, PURCHASED NEW IN 2010, INTERMITTENTLY HAD A LUNGING FORWARD PROBLEM WHEN GOING OVER SPEED BUMPS, POT HOLES ETC. I WOULD HAVE TO STOP IT BY BRAKING QUICKLY, SO I DIDN'T COLLIDE WITH A CAR AHEAD. I INFORMED TOYOTA OF THIS PROBLEM WITHIN THE FIRST YEAR. THEY TESTED IT AND SAID THEY COULD FIND NOTHING. I MENTIONED THIS TO THEM ON VARIOUS OCCASIONS WHEN I TOOK THE CAR FOR ITS PERIODIC MAINTENANCE OF 5000 MILE INTERVALS. ON DECEMBER 26, 2012 I WAS STOPPED WAITING TO GO LEFT WHEN I WAS REAR-ENDED. I WENT TO PULL OVER TO THE SIDE OF THE ROAD TO ASSESS THE DAMAGE. WHEN I ACCELERATED TO GET TO THE SIDE OF THE ROAD,THE CAR TOOK OFF CRAZILY, AT A HIGH RATE OF SPEED FOR ABOUT 6-7 SECONDS, ZIGZAGGING UNCONTROLLABLY ON THE 2 LANE ROAD. IF THERE WERE CARS COMING TOWARD ME, I WOULD HAVE BEEN IN A HEAD ON CRASH. I IMMEDIATELY CALLED TOYOTA SERVICE OF SCRANTON,PA AND ASKED THEM TO SEE AND ASSESS THE CAR'S PROBLEM. THEY MADE AN APPOINTMENT AND CONCLUDED.SAID THERE IS NO PROBLEM INTERNALLY, AND SUGGESTED REMOVING THE AFTER MARKET FLOORMAT. I THEN PROCEEDED TO SHOW THEM THE SAME PROBLEMS MANY CUSTOMERS ARE HAVING WITH THE PRIUS , INCLUDING AN ARTICLE BY STEVE WOZNIAK, THE CO-FOUNDER OF APPLE COMPANY, WHO HAD ACCELERATION PROBLEMS WITH HIS 2010 PRIUS. I CALLED THE MAIN TOYOTA HEADQUARTERS LATER, EXPLAINING THE PROBLEM AND THEY TOO SAID THERE IS NO MALFUNCTION , ONLY MENTIONING THE FLOOR MATS AGAIN.. THIS IS NOT THE CASE AS THE CAR HAS HAD ACCELERATION PROBLEMS FROM THE BEGINNING AND TO FURTHER CLARIFY, I WAS ABLE TO FINALLY STOP THE CAR... THE MAT WAS NO WHERE NEAR THE ACCELERATOR. I AM AFRAID TO DRIVE THIS FOR OTHERS' SAFETY, MY PASSENGERS AND MY OWN SAFETY. I TAKE CARE OF MY CARS FAITHFULLY. YOU CAN VIEW MY RECORDS. I AM ALSO FEARFUL IF I TRADE THIS CAR, SOMEONE ELSE MIGHT GET INJURED OR KILLED. CAN YOU PLEASE CHECK AND ADVISE. *TR

THE UNINTENDED ACCELERATION ACCIDENT HAPPENED ON 7/18/2012, ~6:20 PM AT COMPANY'S PARKING LOT. I BACKED MY 2010 PRIUS SLOWLY. THEN I SAW A CAR COMING ON MY WAY. BUT BEFORE I TOOK ANY ACTION, THIS PRIUS SUDDENLY STARTED ACCELERATING, IT WENT WILDLY, AND TURNED MORE THAN 360 DEGREE BACKWARD IN THE PARKING LOT IN JUST A FEW SECONDS. SINCE THE CAR PARKED BETWEEN A BUILDING AND A SLOP, FROM THE FRONT MIRROR, FIRST, I SAW THE BUILDING WALL AND GLASSES, THEN I SAW THE SLOPE, THEN I SAW A CAR PARKED CLOSE TO MY CAR: NO! DON'T HIT THAT CAR! THAT IS THE LAST THING I REMEMBER. BECAUSE OF THE FAST TURNING OF THE CAR AND BECAUSE I WAS SO TERRIBLY SCARED, I LOST CONSCIOUS AFTER THAT UNTIL THE PRIUS HIT THE TRUCK AND BOUNCED BACK AND STOPPED BY ITSELF. AFTER A FEW SECONDS, I WOKE UP AND REALIZED: I AM STILL ALIVE. I GOT OFF THE CAR AND SAW PRIUS PASSED THE TWO CURBS AND HIT THE TRUCK. THE TWO TIRES ON THE DRIVER SIDE GOT FLAT BECAUSE THEY PASSED THE CURB VERY FAST. I WAS SO SCARED THAT I COULDN'T RECALL OF ANYTHING FOR A FEW DAYS UNTIL WEEKEND. WHY DID THE CAR LOSE CONTROL? ONE MAY ARGUE THAT I STEPPED ON THE ACCELERATOR. THIS COULD HAPPEN TO NEW DRIVERS, BUT NOT TO ME BECAUSE I HAVE BEEN DRIVING FOR SO MANY YEARS AND ALWAYS A GOOD DRIVER. MANY TIMES I SAW A CAR ON MY WAY WHEN I WAS BACKING, I ALWAYS STOPPED RIGHT AWAY. AND I WAS HEALTHY IN A NORMAL DAY IN NORMAL MODE, ALERT AS USUAL. WHY WOULD I STEP ON ACCELERATOR WHEN BACKING? EVEN IF I MIS-STEPPED ON THE ACCELERATOR, I CAN ALWAYS SWITCH TO BRAKE RIGHT AWAY. BUT I COULD?T DO ANYTHING ABOUT THE CAR ON THE DAY. IT WAS OUT OF CONTROL COMPLETELY. AFTER I LOST CONSCIOUS, MY HANDS WERE OFF THE STEERING WHEEL AND MY FOOT DIDN'T STEP ON ANYTHING, THE CAR DIDN'T SLOW DOWN BUT STILL MOVED FAST AND PASSED TWO CURBS EASILY. SUCH A MANIPULATION CAN ONLY BE DONE WHEN THE CAR IS IN ACCELERATION, AND BY ITSELF. PLEASE INVESTIGATE IT ASAP! *TR

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 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

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.
