BRAKE ACTUATOR HAS GONE OUT GIVING A CODE OF C1391. I HAVE HAD THE CAR LESS THAN A YEAR AND THE BRAKES ARE NOW GRABBY AND NOT FUNCTIONING PROPERLY. THIS IS A KNOWN PROBLEM WITH THE GEN 2 PRIUS (MY PREVIOUS CAR) AND WAS COVERED UNDER AN EXTENDED WARRANTY. APPARENTLY THE GEN 3 PRIUS HAS THE SAME ISSUE AND TOYOTA HAS EXTENDED THE WARRANTY OF THE 2010 PRIUS TO THE MANUFACTURING DATE OF 11/2010. MY PRIUS WAS MANUFACTURED IN 12/2010 AND I WAS JUST NOTIFIED IT WOULD BE $4000 TO FIX THE ISSUE THAT IS A KNOWN MANUFACTURING DEFECT. APPARENTLY TOYOTA DIDN'T FIX THE PROBLEM THE FIRST TIME AND IT'S A DIRECT SAFETY ISSUE WHEN THE BRAKES DON'T WORK AS INTENDED.

THE PROBLEM MY CAR EXPERIENCED HAPPENED WHILE THE VEHICLE WAS IN MOTION ON I-110 IN PENSACOLA, FLORIDA AND PRESENTED ITSELF ABRUPTLY (THROUGH THE CAR'S WARNING INDICATORS AT LEAST) ON FRIDAY, AUGUST 31ST HEADED TO PENSACOLA BEACH FOR LABOR DAY WEEKEND FROM OUR HOME IN BATON ROUGE, LOUISIANA. ALL THE CAR'S BRAKE WARNING LIGHTS CAME ON SIMULTANEOUSLY AND WITHOUT WARNING, THE MASTER BRAKE LIGHT, THE ABS LIGHT, FIVE DIFFERENT LIGHTS IN ALL. I PULLED OFF THE INTERSTATE, WENT TO AN AUTOZONE STORE, CHECKED THE BRAKE FLUID LEVEL AND BRAKE PADS (ALL LOOKED NOMINAL) AND GOT THE CAR'S COMPUTER CHECKED FOR WARNING CODES (NONE CAME UP). SEEING NOTHING CATASTROPHIC, BUT BEING UNSURE OF WHETHER OUR CAR WAS REALLY SAFE TO DRIVE EVEN THOUGH THE BRAKES STILL FELT FUNCTIONAL (IF A BIT OFF), WE GOT THE CAR BACK TO BATON ROUGE AND BROUGHT IT TO THE LOCAL TOYOTA DEALERSHIP'S (ALL-STAR TOYOTA, ON AIRLINE HIGHWAY) SERVICE DEPARTMENT. WE HAD NOTICED FOR SOME WEEKS PRIOR INCREASINGLY FREQUENT BUZZING SOUNDS ' ANYONE WITH A PRIUS KNOWS THESE, SUCH AS WHEN YOU TURN THE CAR OFF ' MADE BY (I'M TOLD) THE CAR'S BRAKE ACTUATOR PRESSURIZING THE BRAKE FLUID. THIS ESCALATING FREQUENCY OF THE NOISE, AND A CERTAIN CONSTANT 'PULSING' OF THE SOUND WHEN THE BRAKE WAS SLIGHTLY APPLIED, BUT NOT PUSHED DOWN TO THE FLOOR ' I NOW UNDERSTAND TO BE SYMPTOMATIC OF A FAILING BRAKE ACTUATOR. FOLLOWING SOME RESEARCH, I DISCOVERED IN 2013 TOYOTA ISSUED A RECALL FOR THOUSANDS OF 2010 PRIUS AND OTHER TOYOTA AUTOMOBILES FOR A PROBLEM WITH BRAKE ACTUATORS; ALSO, IN 2016, A WARRANTY EXTENSION AND PART REPLACEMENT WAS OFFERED TO HUNDREDS OF THOUSANDS OF 2004 THROUGH 2009 TOYOTA PRIUS VEHICLES FOR PROBLEMS WITH BRAKE ACTUATORS. IN THAT MORE RECENT MATTER, OWNERS WERE OFFERED A WARRANTY EXTENSION TO 10 YEARS AFTER FIRST USE OF THE CAR OR 150,000 MILES, OR UNLIMITED MILEAGE OR AGE UP TO THE END OF 2017.

GOT IN CAR ONE MORNING AND ALL THE BRAKE / TRACTION CONTROL SYSTEM RELATED LIGHTS ARE ON. TURNED CAR OFF, WAITED 10 MINUTES RESTARTED CAR AND LIGHTS ARE STILL ON. TESTED BRAKE FUNCTION IN YARD, REDUCED BUT STILL ABLE TO GET CAR STOPPED. TOOK IT TO SHOP AND READ CODES, CAME BACK AS THE ACTUATOR WHICH IS ALREADY RECALLED ON PREVIOUS YEAR MODEL PRUIS', OBVIOUSLY THEY DID NOT FIX THE ISSUE ON THE EARLY GEN 3 MODELS (2010 & 2011). I HAVE FOUND MULTIPLE OTHER PEOPLE WITH GEN-3'S THAT HAVE HAD THE SAME ISSUE OS THESE SHOULD BE INCLUDED IN THE GEN-2 RECALL BECAUSE THEY ARE HAVING THE SAME ISSUE. WITH IT BEING A DEALER ONLY PART AT $4500-$5000 (PARTS AND LABOR) TO FIX ON A CAR THAT'S ONLY WORTH ABOUT $10,000 I WONDER IF IT'S REALLY WORTH FIXING. AT THIS POINT THE CAR IS PARKED BECAUSE WITH THE DIMINISHED BRAKING PERFORMANCE I DON'T FEEL SAFE DRIVING IT.

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.

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.
