I WAS IN THE RIGHT LANE TRAVELING WEST BOUND ON TENNESSEE STREET IN TALLAHASSEE, FL, AND AS I WAS GOING THROUGH THE LIGHT AT THE CORNER OF TENNESSEE AND MONROE STREET, THE TRAFFIC STOPPED JUST PAST THE INTERSECTION. AS I WAS ENTERING THE INTERSECTION, I APPLIED MY BRAKES BUT THEY WENT STRAIGHT TO THE FLOOR AND A WARNING LIGHT STARTED BLINKING. I HAD ONE OF TWO CHOICES; HIT THE CAR IN FRONT OF ME OR HIT THE CURB FOR THE SIDEWALK CLOSE TO WHERE A MAN WAS STANDING WITH HIS BICYCLE. LUCKILY I HAD JUST ENOUGH ROOM TO GO BETWEEN THE BACK-END OF THE CAR IN FRONT OF ME AND THE MAN ON THE SIDEWALK. FORTUNATELY NO ONE WAS INJURED IN MY ACCIDENT, I JUST SCARED THE MAN VERY BADLY, BUT THE REPAIRS TO MY CAR ARE PROBABLY GOING TO BE MORE THAN $4,000. *TR

OK, THIS TYPE OF INCIDENT (LOSS OF BRAKING AT LOW SPEEDS) HAS HAPPENED REPEATEDLY IN THIS VEHICLE, DESPITE A RECALL IN 2010 AND "SOFTWARE FIX". THE DATE LISTED IS APPROXIMATE. I FELT COMPELLED TO PROVIDE THIS INFORMATION AFTER HAVING THIS HAPPEN TWICE IN THE PAST WEEK, IN THE HOPES THAT SOME PERMANENT FIX CAN BE MADE AVAILABLE, AND TO WARN PROSPECTIVE BUYERS TO BE CAUTIOUS. IN ALL INCIDENTS, WHEN TRAVELING OVER BUMPS IN A ROAD WITH THE BRAKES ENGAGED, THERE IS A SUDDEN SLIGHT "ACCELERATION", BUT IN ACTUALITY, PROBABLY JUST THE MOMENTARY LOSS OF BRAKING. THIS HAPPENS WHEN GOING OVER: (1) MANHOLE COVERS (2) POTHOLES (3) SLIGHT DIPS IN THE ROAD (FROM SUBSIDING ROAD PATCHING AREAS). DOES NOT APPEAR TO BE WORSE IN WET CONDITIONS, AND HAS ONLY HAPPENED TO ME AT LOW SPEEDS (~5 -- ~ 20 MPH). NOTE THAT ORIGINAL CARPETED MATS WERE REPLACED WITH ONES THAT FIT A BIT BETTER, AND DO NOT CAUSE ANY ISSUES WITH THE ACCELERATION PEDAL. ONCE THE BUMP IS PASSED OVER, NORMAL BRAKING OCCURS. WHEN I FEEL THIS VEHICLE MOMENTARILY LOSE BRAKING, I QUICKLY LET OFF THE BRAKE FOR A SPLIT SECOND, AND RESUME BRAKING. I HAVE GOTTEN USED TO THIS DEFECT, BUT I SURE WOULD LIKE SOMEONE TO INVESTIGATE AND PROVIDE A QUALITY RECALL FIX. THIS BRAKING ISSUE HAS HAPPENED IN NORTH CAROLINA (WHERE THE VEHICLE WAS PURCHASED) AND IN MASSACHUSETTS. THANK YOU. *TR

WHEN I ENCOUNTER A BUMP WHILE APPLYING THE BRAKES IN MY 2010 TOYOTA PRIUS, THE BRAKES FULLY DISENGAGE MOMENTARILY. THIS CAUSES THE CAR TO JOLT FORWARD UNEXPECTEDLY. MY FOOT IS NOT COMING OFF THE BRAKE AT ALL WHEN THIS HAPPENS, SO I KNOW I AM NOT THE CAUSE OF IT. I RECEIVED A RECALL NOTICE BY MAIL IN FEBRUARY 2010 TO ADDRESS JUST THIS ISSUE. I TOOK THE CAR TO THE NEAREST TOYOTA DEALERSHIP TO HAVE THE RECALL WORK COMPLETED. IT WAS INTENDED TO FIX THE MALFUNCTION IN THE ANTI-LOCK BRAKE SYSTEM THAT CAUSED THE BRAKES TO DISENGAGE WHEN THE CAR HITS A BUMP. THE RECALL WORK WAS COMPLETED, BUT THE PROBLEM WAS NOT RESOLVED. THE BRAKES STILL DO THE EXACT SAME THING AND FULLY DISENGAGE WHEN I HIT A BUMP WHILE BRAKING. THIS IS UNQUESTIONABLY DANGEROUS AND A SERIOUS SAFETY HAZARD. *TR

TOYOTA DEALERSHIP WAS CALLED AND SAID THAT THE VEHICLE SHOULD BE FINE - SYSTEM HAD CLEARED WITH PART REPLACEMENT - "MAYBE IT WAS A BAD PART OR THERE COULD BE AIR IN THE LINES." VEHICLE IS PRESENTLY AT THE DEALERSHIP AWAITING INSPECTION. FORTUNATELY, NO ACCIDENTS OR INJURIES OCCURRED ON THESE DATES. HOWEVER BECAUSE OF THE LOSS OF BRAKES AND NEAR ACCIDENTS THIS VEHICLE IS NOW A THREAT TO MY SAFETY. SO FAR I HAVE BEEN LUCKY - I DO NOT WANT TO TAKE A CHANCE WITH THE THIRD BEING THE TIME THAT I AM IN A SERIOUS ACCIDENT. *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.

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

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.
