I HAVE A 2010 PRIUS AND SAW AN ARTICLE ABOUT THERE BEING POSSIBLE BRAKE PROBLEMS WITH THE MODEL. I HAVE HAD THIS PROBLEM PROBABLY ABOUT 6 TIMES SINCE I GOT THE CAR LAST JULY AND, WHEN I MENTIONED IT TO THE DEALER, THEY SAID THERE WASN'T ANYTHING WRONG WITH THE BRAKES WHEN THEY RAN THE DIAGNOSTIC. WHEN IT HAPPENS, I'M IN THE PROCESS OF BRAKING, AND THERE'S A "PUSH", ALMOST LIKE THE BRAKES DIDN'T "TAKE", FOLLOWED BY A LOSS OF STEERING FOR A SECOND OR TWO. IT'S ALSO HAPPENED TO MY HUSBAND ONE TIME. THERE DOESN'T SEEM TO BE ANY RHYME OR REASON AS TO WHEN IT HAPPENS (WET ROAD VS. DRY ROAD, TURNING OR GOING STRAIGHT, FLAT OR HILL). I ORIGINALLY ASSOCIATED THE PROBLEM WITH THE BRAKES BECAUSE I ALSO HAVE THE "SLIDING" ICON COME ON THE DASHBOARD WHEN I'M COMPLETELY STOPPED AND LEAN FORWARD IN MY SEATBELT. HOWEVER, I'M NOW WONDERING IF IT'S NOT THE BRAKES, BUT THE TRANSMISSION, SINCE IT SORT OF FEELS LIKE IT'S NOT DOWNSHIFTING WHEN IT'S SUPPOSED TO, OR IT SHIFTS BACK INTO A HIGHER GEAR FOR A SECOND WHILE BRAKING. I CAME TO THIS CONCLUSION AFTER WAITING IN THE CAR WHILE IT WAS RUNNING. WITH THE CAR ON, EMERGENCY BRAKE ON, BUT NOT IN PARK, THERE WAS A DEFINITE "JOLT" WHEN THE GAS ENGINE WOULD TURN ON AND THEN OFF AGAIN A FEW MINUTES LATER. ALTHOUGH THERE HASN'T BEEN A CRASH YET, THERE WERE TWO TIMES WHEN IT CAME REALLY CLOSE TO THAT, AS I WAS TURNING AND ALMOST HIT THE CARS ON THE SIDE STREET THAT WERE IN THE LEFT TURN LANE WAITING TO TURN ONTO THE STREET I HAD BEEN TRAVELING ON. *TR

ON THURSDAY, JANUARY 28TH MY WIFE DROVE OUR 2010 TOYOTA PRIUS TO WORK. THE WAS A SLIGHT COATING OF SNOW ON THE GROUND. LESS THAT ONE BLOCK FROM OUR HOUSE, DRIVING AT NO MORE THAN 10-15 MPH SHE APPLIED THE BRAKES TO STOP AT A STOP SIGN. SHE REPORTED THAT THE BRAKES SEEMED TO LOCK (NOT THE NORMAL ABS FEEL) AND SHE LOST CONTROL OF THE CAR, WHICH THEN SLID/SKIDDED INTO A CURB WHICH PUNCTURED THE FRONT PASSENGER TIRE. THE CAR APPEARED TO HAVE ONLY A PUNCTURED TIRE WHICH WAS CHANGED BY A AAA SERVICE TRUCK. AFTER THE TIRE WAS CHANGED AND THE SERVICE TRUCK LEFT, I ATTEMPTED TO DRIVE THE VEHICLE TO A NEARBY TIRE DEALER. AS I TRIED TO DRIVE THE CAR, I HEARD AND FELT A LOUD SCRAPING NOISE THAT SOUND AND FELT LIKE THE BRAKES WERE STILL ENGAGED. EVEN THOUGH I WAS NOW ON CLEAR PAVEMENT IF I AT ALL TRIED TO APPLY THE BRAKES,THE ABS WENT ON, BUT IN AN AGGRESSIVE MANNER. THE ABS ALSO WENT ON A COUPLE OF TIMES EVEN WITHOUT ME PUTTING MY FOOT ON THE BRAKES. THE TIRE DEALER SAID HE THOUGHT WE MIGHT HAVE BEEN THE FRAME AND TOLD US NOT TO DRIVE THE CAR. THE CAR WAS TOWED TO A NEARBY BODY SHOP TO BE INSPECTED BY OUR INSURANCE COMPANY, STATE FARM. AS OF FEBRUARY 2, 2010 NO INSPECTION HAS TAKEN PLACE. IT IS OUR CONTENTION THAT SOMETHING MALFUNCTIONED WITH THE BRAKES WHICH CAUSED THE ACCIDENT. *TR

WHEN BRAKING AT LOW SPEEDS, IF THE CAR HITS A MANHOLE COVER OR UNEVEN, BUMPY ROAD, THERE IS A SPLIT-SECOND LOSS IN BRAKING (WHICH FEELS LIKE ACCELERATION SINCE THE DRIVER EXPECTS TO BE DECELERATING AT THE TIME). OTHER PRIUSCHAT SITE USERS HAVE COMPLAINED ABOUT THE SAME PROBLEM WITH THE 2010 PRIUS - SOME USERS CLAIMED THIS WAS "NORMAL" WHEN THE REGENERATIVE BRAKES SWITCH OVER TO HYDRAULIC BRAKES AND THAT THERE WAS REALLY NO LOSS IN BRAKING. IT MAY BE "NORMAL" BUT IT'S SCARY AS HECK WHEN IT HAPPENS AND IF A PEDESTRIAN CROSSES IN FRONT OF THE CAR OR A CAR IN FRONT OF A 2010 PRIUS STOPS QUICKLY UNDER JUST THE WRONG CIRCUMSTANCES, I SUSPECT AN ACCIDENT WOULD RESULT. *TR

TWO SECONDS LATER AFTER SLIDING TO THE END OF MY DRIVEWAY, THE BRAKES CAUGHT. I WAS CONCERNED THAT THE FEELING WAS QUITE ODD, BUT CHALKED IT UP TO THE ICE.

THE SAME FEELING--PUTTING ON THE BRAKES AND HITTING AIR--THEN 2 SECONDS LATER THE BRAKES GRABBED. I IMMEDIATELY DROVE IT TO THE DEALERSHIP AND LEFT IT, CITING BRAKE FAILURE. THEY HAD IT ABOUT 2 DAYS AND NO ONE BELIEVED ME. SAID IT WAS FINE. YESTERDAY, 2/1/10, AND AGAIN TODAY, 2/2/10, IT DID IT AGAIN TO AND FROM WORK. I DO NOT FEEL SAFE IN THAT CAR.

I HAVE BEEN DRIVING MY 2010 PRIUS FOR 6 MONTHS AND HAVE EXPERIENCED THE FOLLOWING NEARLY 10 TIMES: WHEN BRAKING, IF A POTHOLE OR BUMP IN THE ROAD IS HIT, THE CAR SEEMINGLY JERKS FORWARD/ACCELERATES FOR A SPLIT SECOND. THIS RESULTS IN LESS CONTROL OVER WHERE THE CAR COMES TO A COMPLETE STOP. THE MOST UNNERVING INSTANCES OF THIS OCCUR WHEN APPROACHING THE END OF A ROAD OR A CROSSWALK. I NEARLY HIT A CHILD BECAUSE OF THIS UNPREDICTABLE REACTION TO A POTHOLE. ALSO, THE BRAKES ARE LESS EFFECTIVE IN SNOW THAN ANY OTHER CAR I'VE EVER DRIVEN. NO MATTER HOW SLOW I'M GOING OR HOW HARD I HIT THE BRAKES, I'VE FOUND THAT I'M GUARANTEED TO SKID SEVERAL FEET, OFTENTIMES INTO INTERSECTIONS/TRAFFIC. PERHAPS UNRELATED TO THE POTHOLE ISSUE, BUT MAYBE NOT. BOTH ISSUES ARE EXTREMELY DANGEROUS. *TR

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
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.
