I WAS DRIVING ON A BUSY CITY STREET AND AS I WAS APPROACHING AN INTERSECTION I STEPPED ON THE BRAKE, BUT THE BRAKE FAILED. AS I STEPPED ON THE BRAKE PEDAL, THE PEDAL WENT ALL THE WAY DOWN TO THE FLOOR. I KEPT ON HITTING THE BRAKE BUT IT WAS NOT WORKING. MY CAR WAS NOT STOPPING. THE ABS AND SLIP INDICATOR LIGHTS TURNED ON. I WAS ON A PANIC BECAUSE I WOULD BE HITTING OTHER CARS AND POSSIBLY PEOPLE BECAUSE I WAS APPROACHING AN INTERSECTION. LUCKILY THE TRAFFIC LIGHT TURNED GREEN AS I APPROACHED SO I MADE THE TURN AND STILL I WAS NOT STOPPING. THE CAR WAS CONTINUOUSLY MOVING. AS I WAS APPROACHING ANOTHER INTERSECTION, I TRIED STEPPING ON THE PARKING BRAKE, IT DECELERATED BUT NOT STOPPING. BEFORE IT ALMOST HIT ANOTHER CAR ON THE INTERSECTION, IT STOPPED WHILE I WAS STEPPING ON THE PARKING BRAKE REAL HARD WITH ABATED BREATH.

I WAS DRIVING STRAIGHT ON A CITY ROAD WITH THE FLOW OF HEAVY TRAFFIC AT ABOUT 40 MILES PER HOUR WHEN THE CAR IN FRONT OF ME CAME TO A SUDDEN STOP. I IMMEDIATELY SLAMMED ON MY BRAKES VERY HARD. AT THE TIME I DID THIS I HAD PLENTY OF SAFE DISTANCE BETWEEN US. BUT, THE BRAKES NEVER CAME ON AND I ENDED UP RUNNING INTO THE REAR END OF AN SUV AT APPARENTLY FULL SPEED WITHOUT ANY NOTICEABLE SLOWDOWN. THE BRAKES DID NOT COME ON. THEY DIDN'T GRAB, AND THEY DIDN'T MAKE ANY SCREECHING NOISE AND THERE WERE NO TIRE MARKS ON THE ROAD. ALSO ALL OF THE AIRBAGS DEPLOYED AND THIS WAS A FRONTAL IMPACT, WHICH WAS VERY SURPRISING AND SUFFOCATING. A CLOUD OF DUST FILLED THE CABIN OF THE CAR AND I COULD NOT BREATHE. I WAS LITERALLY SUFFOCATING UNTIL I WAS ABLE TO OPEN THE DOOR AND GET OUT OF THE VEHICLE. I DIDN'T EVEN FEEL THE SEAT BELT TIGHTEN UP BEFORE THE CRASH. THE BRAKES NEVER FELT LIKE THEY CAME ON AT ALL. *TR *JS

ON 07/20/15 THE BRAKES FAILED COMPLETELY WHILE DRIVING. ON 08/05/16 THE SAME BRAKES FAILED AGAIN WHILE DRIVING. IT IS THE SAME ISSUE VERIFIED BY TWO TOYOTA DEALERSHIPS, (FRONT LEFT CALIPER AND BRAKE PAD REPLACEMENTS NEEDED). THE CAR WAS BOUGHT NEW. THE BRAKES HAVE FAILED TWICE, THEY CITE SAFETY DEFECTS. ON 08/15/16 I PHOTOGRAPHED LEFT FRONT BRAKE ISSUE. THEY CLAIM THEY, "DON'T KNOW WHY IT'S HAPPENING." IT IS CLEAR THE CAR IS UNSAFE AND SHOULD BE REPLACED ENTIRELY. I REPORTED THE FIRST BRAKE FAILURE 07/20/15 THE BRAKES FAILED WHILE DRIVING. THE DEALER STATED IT WAS A SAFETY RELATED DEFECT THAT THEY COULD NOT FIGURE OUT WHY AND THUS SENT THE ORIGINAL BRAKES TO TOYOTA FOR INSPECTION & INVESTIGATION. I NEVER HEARD BACK. ON 08/05/16 (12 MONTHS 15 DAYS LATER, APPROX. 12,000 MILES DRIVEN) THE SAME BRAKE FAILURE HAPPENED AGAIN. FILLED IT WITH BRAKE FLUID ON 08/15/16 MAKE IT TO DEERFIELD TOYOTA (CLOSEST) THAT STATED I WOULD HAVE TO TAKE IT TO THE ORIGINAL TO AVOID PAYING. VERY DANGEROUS. THEN TOOK TO SAME, ERIC JONES, LIPTON TOYOTA, FORT LAUDREDALE, FL, AS LAST TIME. HE STATED THE REPLACED CALIPERS AND BRAKE PADS WERE DEFECTIVE. THE CAR REMAINS THERE, 10 DAYS AWAITING A BACK ORDER. I INQUIRED FURTHER ON 08/22/16 TO WHICH MR. JONES STATED THE CAR WAS BOUGHT NEW WITH DEFECTIVE BRAKES/ CALIPERS AND THAT THEY HAD REPLACED THEM 07/2015 BUT THAT THEY HAD REPLACED THEM WITH TOYOTA DEFECTIVE BRAKES AGAIN. (ESPECIALLY SPECIFICALLY THE FRONT LEFT CALIPER AND BRAKE PADS). BRAKES HAVE FAILED TWICE. IT IS CLEAR THE DEFECTIVE ISSUE IS FROM THE CAR. PHOTOS REVEAL THAT THE REPLACEMENTS NEVER RESOLVED THE ISSUE AS IT HAS BEEN OCCURRING EVER SINCE THEN. TO CONTINUE DRIVING TO SEE IF A 3RD BRAKE FAILURE OCCURS IS TO RISK MINE AND OTHERS ON THE ROAD LIVES. 1ST REPORTED SAFETY CONCERN TO NHTSA ON 07/20/15, REFERENCE #10735054 : RANDY REID. I AM SCARED. HELP PLEASE.

WHEN THE DRIVER HAS TO SLAM ON THE BRAKES REALLY QUICKLY THE CAR DOES NOT SLOWDOWN AT ALL. THE SKID LIGHT COMES ON THE DASH BOARD, BUT OTHERWISE THE CAR DOES NOT STOP. THIS HAPPENS EVEN ON A DRY SURFACE, WITH NO MOISTURE ON THE SURFACE, AT SPEEDS AS LOW AS 20-30 MILES PER HOUR. IT ALMOST ALWAYS DOES IT. IF THE DRIVER LIGHTLY TAP THE BREAKS, THEN THE CAR WILL DECELERATE, BUT NOT IF THE DRIVER HAS TO ABRUPTLY STOPPED. THIS IS QUILT A PROBLEM GIVEN THAT SOMETIMES YOU NEED THE CAR TO STOP SUDDENLY IT IT SIMPLY WON'T AT SPEEDS OF 20 MORE. THE CAR JUST STARTS TO SKID. IT WILL NOT STOP OR GAIN TRACTION WITH THE SURFACE THAT IT IS ON. THIS MEANS THAT IN A SITUATION WHERE THE DRIVER NEEDS TO HIT THE BREAKS ALL THE WAY DOWN, THE CAR STILL WON'T STOP. THIS PROBLEM IS MUCH WORSE IF ON WET OR NEGATIVE SLOPING ROADS. HOWEVER, IT CAN HAPPEN EVEN ON COMPLETE DRY SURFACE.

I WAS DRIVING HOME IN MY 2013 TOYOTA PRIUS ON TUESDAY, DECEMBER 29, 2015, AT APPROXIMATELY 4:30P.M. WHILE TURNING RIGHT FROM THE STREET ON WHICH I LIVE INTO MY DRIVEWAY, THE CAR, AFTER I APPLIED THE BRAKES, SUDDENLY SURGED FORWARD. IN SPITE OF CONTINUOUSLY PUSHING DOWN ON THE BRAKES, THE CAR WOULD NOT STOP. THE DRIVEWAY SHOWS SKID MARKS FROM MY ATTEMPTS TO STOP THE CAR. THE CAR DID NOT STOP. THE BRAKES FAILED. THE CAR SHOT FORWARD, CRASHING INTO THE CLOSED WOODEN GARAGE DOOR AND THE WALL TO THE LEFT OF THE GARAGE DOOR. THE GARAGE DOOR BROKE AND ONE HALF OF THE GARAGE DOOR SPLIT AND WAS PUSHED INTO THE GARAGE. THE GARAGE DOOR COLLAPSED ON MY CAR AS WELL AS ITEMS STORED IN THE GARAGE INCLUDING PARTS OF THE GARAGE STRUCTURE AND LARGE SECTIONS OF A STORAGE UNIT, WHICH WAS BOLTED TO THE WALL. APPROXIMATELY 90% OF MY CAR WAS INSIDE THE GARAGE. I TRIED TO EXIT THE CAR THROUGH THE DRIVER'S SIDE BUT THE DOOR WOULD NOT OPEN. I CRAWLED TO THE TRUNK AREA AND COULD NOT FIND A MECHANICAL RELEASE FOR THAT DOOR. FINALLY I FORCED OPENED THE DRIVER'S SIDE REAR DOOR AND EXITED THE CAR THROUGH THE BROKEN WALL. IF THE BRAKES HAD NOT FAILED THIS WOULD HAVE NOT HAVE HAPPENED. AS A RESULT OF THE BRAKE FAILURE, I HAVE INCURRED SUBSTANTIAL LOSS, INCLUDING THE GARAGE DOOR (A TOTAL LOSS), DAMAGE TO STRUCTURAL SUPPORT TO THE GARAGE WALL, A BUILT-IN GARAGE STORAGE UNIT, CONTENTS STORED IN THE GARAGE AND SUBSTANTIAL DAMAGE TO THE CAR. FORTUNATELY, I DID NOT SUFFER ANY MAJOR PHYSICAL INJURIES, ALTHOUGH FOLLOWING THE COLLISION I EXPERIENCED AND CONTINUE TO EXPERIENCE MUSCLE, JOINT, HIP, NECK AND BACK PAIN AND DISCOMFORT. IN ADDITION, I CONTINUE TO EXPERIENCE EMOTIONAL DISTRESS FROM THIS INCIDENT. I WANT TOYOTA TO PERFORM A COMPLETE DIAGNOSTIC SAFETY CHECK OF ALL SYSTEMS INCLUDING THE BRAKES AND ANY SOFTWARE THAT CONTROLS THE BRAKING SYSTEM.

RECURRING PROBLEM. WHEN BRAKING THE VEHICLE WILL OCCASIONALLY "SLIDE" RATHER THAN BRAKE WHEN THE CAR GOES OVER DIFFERENT ROAD SURFACES. THIS HAPPENS FOR ABOUT THE LENGTH OF THE CAR OR LESS (PROBABLY THE LENGTH OF THE DIFFERENT SURFACE) AND THEN THE BRAKING CONTINUES ONCE THE ROAD IS CONSISTENT AGAIN. I HAVE SPOKEN WITH THE DEALER AND THEY INDICATE THIS IS A KNOWN SYMPTOM OF THE CAR'S DEGENERATIVE BRAKING SYSTEM FUNCTIONING "PROPERLY" WHEN ALL TIRES ARE NOT WORKING IN SYNC. I THINK IT'S A DEFECT THAT WILL EVENTUALLY LEAD TO REAR-END COLLISIONS. THIS HAS OCCURRED WHEN GOING OVER STEEL PLATES, POTHOLES, APPROACHING TOLL-BOOTH STOPS - ALL IN GOOD WEATHER, AND ON SLICK ROAD SURFACES DURING POOR WEATHER.

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.

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.
