2010 TOYOTA PRIUS. CONSUMER STATES BRAKE PROBLEMS. *TGW THE CONSUMER STATED IT APPEARED AS IF THE SOFTWARE PATCH FOR THE 2010 PRIUS WAS NOT ENOUGH AS HE HAS EXPERIENCED ONE MORE OCCURRENCE SINCE GETTING THE PATCH ON MARCH 1, 2010. PRIOR TO THE SOFTWARE PATCH, THE CONSUMER EXPERIENCED BRAKE STUTTERING MAY BE 10 TIMES. THE CONSUMER STATED HE READ WHERE THE SWITCH FROM REGENERATIVE TO MECHANICAL BRAKING OCCURRED AT ABOUT 9 MPH HE NOTICED THAT THE BRAKE STUTTERING SEEMED TO OCCUR CLOSER TO 20 MPH. IT WOULD NOT JUST OCCUR WHEN HITTING A SMALL POTHOLE, BUT SOMETIMES WITH JUST STEADY BRAKING ON SMOOTH SURFACES. ON A SMOOTH SURFACE, THE FEELING WOULD BE A BIT OF A JERK. HE WOULD DECELERATE WITH PRESSURE AGAINST THE SEAT BELT AND HIS HANDS ON THE STEERING WHEEL, THEN THERE WOULD BE 1/4 OF A SECOND WHERE THERE WAS NO PRESSURE BECAUSE THE BRAKES WERE NOT WORKING, THEN HE WOULD JERK FORWARD AS THE BRAKES BEGAN TO WORK AGAIN, THERE WAS A SOMEWHAT DIFFERENT SENSATION WHEN HITTING A SMALL POTHOLE. THE MOST RECENT MOMENTARY BRAKE FAILURE OCCURRED WHILE STOPPING FOR A RED LIGHT. THE CONSUMER STATED HE SLOWED DOWN TO 20 MPH WHEN HE FELT A DIFFERENT TYPE OF STUTTERING THAN PREVIOUSLY. IT MAY HAVE BEEN A DOUBLE STUTTERING, BUT IT SEEMED HARDER. *JB

2010 TOYOTA PRIUS. CONSUMER STATES BRAKE FAILURE IN WHICH THE MALFUNCTION HAPPENED TWICE AND CAUSED AN ACCIDENT. *TGW THE CONSUMER STATED THE FACTORY DEFECT WAS NOT BROUGHT TO LIGHT UNTIL AFTER THE SECOND INCIDENT. ALTHOUGH, TOYOTA CORRECTED THE BRAKE ISSUE, THE CONSUMER HAS COSTS AND OUTSTANDING PROBLEMS WITH THE VEHICLE BECAUSE OF THE DAMAGE DONE IN FIRST INCIDENT, INCLUDING PROBLEMS WITH THE WHEEL BEARING. THE CONSUMER IS REQUESTING TOYOTA REIMBURSE HIM FOR MONIES PAID TO FIX THE VEHICLE AND ALSO TO FIX THE WHEEL BEARING THAT WAS NOT IDENTIFIED AND NOT REPLACED. THE CONSUMER STATED THE FIRST INCIDENT HAPPENED WHEN HE WAS ABOUT TO MAKE A RIGHT TURN. THERE WAS SNOW ON THE ROADS AND AS HE WAS MAKING THE TURN, TRAVELING ABOUT 9 OR 10 MPH, HE STARTED SLIDING TOWARD THE CURB ON THE OTHER SIDE. HE TRIED TO BRAKE, BUT HE CONTINUED TO SLIDE. AN INSTANT BEFORE HE HIT THE CURB, THE ANTI-LOCK BRAKES ACTIVATED, BUT IT WAS TOO LATE. HE SLID INTO THE CURB WITH THE WHEEL TURNED, BROKE THE WHEEL RIM AND FLATTENED THE TIRE. THE SECOND FAILURE OCCURRED WHEN HE WAS COMING OUT OF A MALL PARKING LOT HEADING TOWARD A MAIN STREET. THE CONSUMER STATED HE WAS COASTING TO THE STOP SIGN AND APPLIED THE BRAKES, BUT NOTHING HAPPENED. HE PUSHED THEM AS HARD AS HE COULD AND AGAIN AT THE LAST SECOND THE ANTI-LOCK BRAKES ACTIVATED. *JB

IN THE MIDDLE OF BRAKING, TRYING TO MAKE FULL USE OF THE REGENERATION FEATURE, THE CAR SOMETIMES STOPPED BRAKING MOMENTARILY. I EXPERIENCED THAT THIS WAS MORE LIKELY TO HAPPEN ON A BUMPY ROAD. IN THE 6 MONTHS OR SO I DROVE THE CAR, PRIOR TO THE UPDATE, I EXPERIENCED THIS PROBLEM ROUGHLY 12 TIMES. I AM SAD TO REPORT HOWEVER THAT IN THE TWO WEEKS SINCE THE CAR WAS UPDATED, I HAVE ALREADY EXPERIENCED TWO ADDITIONAL EVENTS AFTER THE UPDATE THAT SEEM EXACTLY LIKE WHAT I EXPERIENCED BEFORE THE UPDATE. I TOOK THE CAR BACK TO MY DEALER (PRESTIGE TOYOTA, IN RAMSEY, NJ) AND SOMEONE THERE TESTED IT AND WAS CONVINCED THAT THE UPDATE WAS INSTALLED.

I WAS GOING DOWN A HILL (APPROX 20MPH) IN MY SUBDIVISION (NORTH ON HARTER FARMS RD) WHEN I SAW A CAR PULLING OUT ONTO THE ROAD FROM HIS YARD. I APPLIED THE BRAKES HARD FOR ABOUT 100YDS BEFORE ATTEMPTING TO TURN INTO PALIMINO DR TO AVOID A COLLISION. I DID NOT MAKE THE TURN AND HIT A STOP SIGN AND THEN THE GUARD RAIL AT APPROX 5MPH. THERE WAS ABOUT 1-2" OF SNOW ON THE ROAD AND I HAD DRIVEN UP THE SAME HILL FROM A STOP WITHOUT SLIPPING A TIRE JUST 15 MIN PRIOR. I NEVER FELT ANY PULSATION FROM THE ABS DURING THE ATTEMPT TO STOP. AFTERWARDS WHEN I GOT HOME I ATTEMPTED TO STOP HARD (TO TEST THE BRAKES) ON LEVEL GROUND AND AGAIN NEVER FELT THE PULSATION FROM THE ABS SYSTEM. THERE WAS BRAKING BUT I FELT IT WAS GREATLY REDUCED. I HAVE NOT RETURNED THE CAR TO TOYOTA FOR THEIR RECALL YET. IF YOU WISH TO EXAMINE THE CAR YOU MAY. I AM SURE YOU CAN DUPLICATE THE RESULTS. *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 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

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.
