EVEN AFTER ALL RECALL WORK WAS PERFORMED THERE IS AN ISSUE BRAKING WITH THE 2010 PRIUS. WHEN BRAKING OVER BUMPY SURFACES YOU OFTEN GET A FEELING THAT THE CAR IS ACCELERATING RATHER THAN BRAKING. I DO NOT THINK THE CAR ACTUALLY ACCELERATES - IT IS MORE OF AN ISSUE THAT THE BRAKES RELEASING WHEN I BROUGHT IT TO THE ATTENTION OF MY TOYOTA DEALER THEY DO NOT THINK IT IS A PROBLEM. WHEN IT HAPPENS IN BUMPER TO BUMPER TRAFFIC IT CAN REALLY SCARE YOU! I WORRY LETTING MY KIDS DRIVE THE CAR. AND NO - IT IS THE ABS IS KICKING IN. *KB

ONCE I GOT ON THE FREEWAY, MY BRAKE LIGHT, ABS LIGHT AND SLIPPAGE LIGHTS ALL CAME ON AT ONCE (ALONG WITH BEEPING NOISE THAT DOES NOT GO AWAY). I PULLED OVER TO THE SIDE OF ROAD AND NOTICED THAT MY BRAKES HAD DEGRADED BY ABOUT 75 PERCENT.....WHILE I DID HAVE SOME BRAKES IT WOULD HAVE NOT BEEN ENOUGH FOR AN EMERGENCY STOP OR NORMAL TRAFFIC BRAKING. *KB

WHILE DRIVING ON INTERSTATE, THE BRAKE AND VEHICLE STABILITY ASSIST LIGHTS SUDDENTLY WENT ON AND A BEEPING ALARM SOUNDED. THE BRAKES WERE NOT VERY EFFECTIVE, AND IT WAS VERY DIFFICULT TO SLOW DOWN AND STOP THE CAR WHEN WE PULLED OVER. WE HAD THE CAR TOWED TO THE DEALERSHIP, WHERE THEY INFORMED US THAT THE ABS PUMP AND THE ENTIRE BRAKING SYSTEM NEEDED TO BE REPLACED...ON OUR ONE YEAR OLD CAR! PARTS ALONE TOTALED OVER $4000 DOLLARS, WITHOUT LABOR. TOYOTA WAS UNWILLING TO REPLACE, AS THE CAR WAS OUT OF WARRANTY FOR MILEAGE. CLEARLY A DEFECTIVE SYSTEM IN OUR CAR, BUT THEY WERE NOT WILLING TO STAND BEHIND THEIR PRODUCT TO COVER. ANGRY CUSTOMER, ESPECIALLY GIVEN THE FACT THAT TOYOTA STATES THAT THEY WANT TO RESTORE CUSTOMER FAITH IN THEIR PRODUCT. WE WERE LUCKY THAT INJURY DID NOT RESULT FROM THE FAILURE OF THE PARTS NEEDED TO STOP THE CAR.

MY DRIVING RECORD WAS CLEAN UNTIL THIS 2010 PRIUS. IN ONE YEAR I HAVE HAD TWO ACCIDENTS AND SEVERAL INCIDENTS, ALL OF WHICH I AM NOW CONVINCED DUE TO BRAKE FAILURE. THE FIRST ACCIDENT TOOK PLACE END OF DECEMBER 2010. I WAS GOING ONLY ABOUT 10 MPH. I HIT THE BRAKES REPEATEDLY TO TRY TO GET THE CAR TO STOP. AT THE TIME I THOUGHT THE CAR DID NOT STOP BECAUSE OF ICE, BUT NOW AFTER THIS 2ND ACCIDENT AND RESEARCHING OTHER PRIUS REPORTS, I AM CONVINCED THIS FIRST ACCIDENT WAS ALSO BECAUSE THE BRAKES FAILED TO WORK. SINCE I DID NOT SUSPECT THIS AT THE TIME, I DID NOT REPORT IT OR HAVE THE BRAKES CHECKED WHEN THE CAR WAS REPAIRED. THE 2ND ACCIDENT WAS LAST NIGHT, DEC 8TH, 2011. I WAS TRAVELING BETWEEN 25-30 MPH. THE BRAKES CLEARLY FAILED TO WORK, AND I HIT A CAR STOPPED AT THE TRAFFIC LIGHT IN FRONT OF ME. I HAD PLENTY OF DISTANCE TO STOP. THE CAR DID NOT SLOW DOWN, IF ANYTHING, IT MAY HAVE SPEEDED UP, BUT I CANNOT DEFINITELY SAY THIS, AS I WAS TOO FREAKED OUT LOOKING AT THE CAR I WAS GOING TO HIT TO CHECK MY SPEED. THE ROAD WAS NOT ICY. THE IMPACT DEMOLISHED THE FRONT END OF THE PRIUS. MY AIR BAG ALSO DID NOT INFLATE. I HAVE WHIPLASH FROM THIS SECOND ACCIDENT. FORTUNATELY NO ONE ELSE WAS INJURED. I NOW REALIZE I HAD SEVERAL OTHER BRAKE 'SLIPPAGE' PROBLEMS LAST WINTER THAT DID NOT RESULT IN ACCIDENTS AND I DID NOT IDENTIFY THEN AS BRAKE PROBLEMS. I THOUGHT IT WAS MY SNOW TIRES, EVEN THOUGH THEY WERE BRAND NEW. I TOOK THE CAR BACK TO THE TIRE DEALER LAST MONTH WHO SAID THEY HAD NO OTHER COMPLAINTS ABOUT THAT BRAND OF TIRE, BUT I SO CONCERNED I HAD THEM REPLACE THE TIRES ANYWAY WITH NEW ONES OF A DIFFERENT BRAND. I HAVE OPENED A CASE WITH TOYOTA AFTER I STARTED TO RESEARCH 2010 PRIUS AND FOUND A RECALL ON THIS MODEL AND YEAR FROM BEFORE I LEASED THIS CAR. TOYOTA SAYS THERE IS NOT A RECALL ON MY VIN#. I WANT TOYOTA TO TAKE RESPONSIBILITY FOR THIS ACCIDENT AND TAKE BACK THE CAR. *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.

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.

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.
