I PURCHASED A 2010 TOYOTA PRIUS IN SEPT 2009. SINCE THEN, I HAVE HAD 3 OR 4 INSTANCES WHERE THE BRAKES LET GO MOMENTARILY AS MOUNTING REPORTS ARE SIMILARLY DESCRIBING. EACH INSTANCE HAS OCCURRED AT ROUGHLY THE SAME PLACE ON MY DRIVE HOME FROM MY CHILD'S DAY CARE, WHERE THE ROAD IS SLIGHTLY UNEVEN AND SLOPING DOWN, AS I AM BREAKING FOR A STOP SIGN. SINCE THIS IS A RESIDENTIAL AREA, I AM NOT DRIVING FAST TO BEGIN WITH (<20 MPH), AND THE BRAKES ONLY LET GO FOR 1-2 SECONDS. PRIOR TO HEARING ALL OF THESE OTHER REPORTS, I HAD NOT THOUGHT TO FILE MY OWN AND FOR THAT I APOLOGIZE. MY FEELING IS THAT UNLESS THIS ISSUE IS CORRECTED SOMEHOW BY TOYOTA, THESE INSTANCES WILL CONTINUE, AND I DO SEE POTENTIAL FOR AN ACCIDENT. *TR

MY HUSBAND AND I BOUGHT A 2010 TOYOTA PRIUS IN NOVEMBER 2009. WE BOTH HAVE NOTICED A SORT OF JERKY FEELING WHILE BRAKING OVER A SMALL BUMP OR POTHOLE BUT WE DIDN'T THINK MUCH OF IT UNTIL LAST NIGHT WHEN I WAS DRIVING HOME WITH MY CHILDREN. I WAS DRIVING DOWN A RESIDENTIAL AREA AT ABOUT 30 MILES/HR. AND WAS SLOWING DOWN TO STOP AT A RED LIGHT. WHILE I WAS BRAKING I HIT A MEDIUM SIZED POT HOLE. MY CAR JUST LEAPT FORWARD ABOUT 10 FEET. I HAD MY FOOT ON THE BRAKE FIRMLY THE ENTIRE TIME BUT THE CAR WOULD NOT STOP. FINALLY MY CAR CAME TO A STOP. I WAS VERY SHAKEN BY THIS INCIDENT. IF THERE WAS A CAR IN FRONT OF ME I WOULD HAVE TOTALLY REARENDED THEM. I CAME HOME AND IMMEDIATELY CALLED THE TOYOTA DEALERSHIP. I LEFT A MESSAGE WITH THE SERVICE DEPARTMENT. MY CALL WAS RETURNED BY THE MANAGER THIS MORNING. SHE SAID THAT SHE HAD NOT HEARD ANYTHING FROM TOYOTA ABOUT ANY BRAKE ISSUES AND THEN SHE ASKED ME WHETHER I WAS SPEEDING! SHE DID NOT SEEM TO BELIEVE ME AND BASICALLY SAID THAT THERE WAS NOTHING THAT THEY COULD DO.*TR

MOMENTARY LOSS OF BRAKING ON A 2010 PRIUS MODEL IV. VEHICLE WAS PURCHASED ON THE 30TH OF SEPTEMBER 2010 AND CURRENTLY HAS 3460 MILES. DURING THE FIRST WEEK OF OPERATION THE BRAKES DID NOT SEEM TO WORK CORRECTLY. WE THOUGHT THIS MIGHT BE DO TO THE FACT THAT THE CAR WAS NEW AND THE BRAKES NEED TO BE USED AS A BRAKE IN PERIOD. WE NOTIFIED THE DEALERSHIP DURING THE SECOND WEEK OF OPERATION. THEY INDICATED THAT THIS WAS THE FIRST CONCERN THEY HAVE RECEIVED. THEY STATED THAT WHEN WE BRING IT IN FOR THE FIRST 5000 MILE SERVICE THEY WOULD CHECK THE BRAKES. SINCE THE MOMENTARY LOSS OF BRAKING DID NOT HAPPEN THAT OFTEN AND ONLY ON BUMPY ROADS OR OVER SPEED BUMPS WE WERE NOT TOO CONCERNED.I DID CALL THE DEALERSHIP AGAIN ON 2/4/2010 AND THE SERVICE DEPARTMENT STATED THEY HAD NOT RECEIVED ANY INFORMATION ON CORRECTING THE PROBLEM. WHAT WAS INTERESTING IS THAT A PERSON IN THE SERVICE DEPARTMENT WHO OWNS A 2006 PRIUS STATED THAT THE PROBLEM HAS BEEN AROUND FOR YEARS BUT IS MUCH MORE NOTICEABLE IN THE 2010 MODEL.. TOYOTA HAS ASSIGNED A CASE NUMBER TO OUR COMPLAINT ( 1002108541 ). NO ACCIDENT TO DATE BUT DRIVING THE VEHICLE SHOULD NOT INCLUDE WORRYING WHETHER OR NOT THE BRAKES WILL STOP IN TIME. *TR

WE OWN A 2010 TOYOTA PRIUS WHICH WE PURCHASED IN JUNE OF 2009. ON SIX DIFFERENT OCCASIONS WE HAVE EXPERIENCED BRAKING PROBLEMS. ONE INCIDENT WAS ON ICE AND WHEN THE BRAKE PEDAL WAS PRESSED THE RESPONSE WAS AS IF THERE WERE NO BRAKES AT ALL AND THE VEHICLE SLID FREELY FOR A BRIEF MOMENT. THE OTHER FIVE INCIDENTS INVOLVED BRAKING ON A ROUGH SURFACE WHEN APPROACHING A STOP SIGN (3 DIFFERENT LOCATIONS). IN THESE CASES, WHEN THE BRAKE WAS PRESSED THE CAR DID NOT BEGIN TO STOP IMMEDIATELY. IN FACT I GOT THE FEELING THAT THE CAR HAD BEEN "HIT FROM THE REAR" AND I JERKED BACK INTO MY SEAT A LITTLE AND FELT THAT THE CAR FLOATED AHEAD BEFORE IT BEGAN TO STOP. THIS ALL HAPPENED VERY QUICKLY. I TRIED TO REPLICATE THE SITUATION AND WAS SUCCESSFUL ONCE. IN ALL BUT ONE OF MY EXPERIENCES WITH THIS DILEMMA, THE ROAD WAS ON A SLIGHT DOWNWARD SLOPE APPROACHING THE STOP SIGNS. THERE SEEMS TO BE A CERTAIN SPEED THAT IS NEEDED FOR IT TO HAPPEN. TOYOTA EXAMINED THE BRAKES AND SAID THEY WERE OK. OBVIOUSLY, THEY ARE NOT. *TR

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.

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.

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.
