What 684 owners told NHTSA about the 2012 Toyota Prius C

IGUALMENTE QUE LOS CARROS PRIUS REGULARES, EL CUAL HAY UNA GARANTIA EXTENDIDA, MI EL AUTO DAO LA BOMBA DE FRENOS, LO CUAL ES MUY COSTOSA, ESTA GARANTIA SOLO ES SOLO PARA PRIUS REGULARES IGUALMENTE UTILIZAN EL MISMO SISTEMA. SE DEBE VERIFICAR PORQUE NO CUBRE LOS OTROS AUTOS YA QUE TIENEN EL MISMO SISTEMA.

THE PROBLEM STARTED WITH A CHIRPING NOISE WHEN THE BRAKE PEDAL IS DEPRESSED. TODAY THE CAR APPEARS TO LOSE REGENERATIVE BRAKING CHARGING. THE VEHICLE STABILITY CONTROL AND ABS LIGHT AND BRAKE LIGHT CAME ON. THE BRAKE APPEARED TO BE MUSHIED.

I REPLACED MY BRAKE BOOSTER THREE TIMES IN TWO MONTHS.STILL I HAVE BIG ISSUES WITH TOYATA COMPANY.

MY ENTIRE BREAKING SYSTEM WENT OUT WHILE DRIVING TO WORK ON A BUSY ROAD, WHERE I HAD TO PULL OVER TO THE SIDE TO SEE WHAT WAS WRONG, AS I HAD NEVER SEEN THOSE FIVE LIGHTS LIGHT UP EVER, AS THIS IS NOT A TYPICAL ISSUE THAT WOULD EVER BREAK WITHOUT A MANUFACTURING ISSUE. I WAS NEVER NOTIFIED OF A SPECIFIC ISSUE WITH CERTAIN 2011-2015 PRIUS VEHICLES THAT ARE INVOLVED IN A CUSTOMER SUPPORT PROGRAM ZJB. I HAVE NOW PAID $100 TO TOYOTA TO DIAGNOSE THIS PROBLEM, WHICH WAS NOT NECESSARY, AS IT IS OBVIOUSLY THE EXACT ISSUE (5 LIGHTS LUMINATED) FROM THE CUSTOMER SUPPORT PROGRAM, AND THEY HAVE TOLD ME THAT I WAS NOT NOTIFIED OF THE ISSUE BECAUSE MY VIN IS NOT INCLUDED IN THE PROGRAM. IT HAS BEEN DIAGNOSED WITH THE EXACT BREAK BOOSTER ISSUE LISTED IN THE LETTER SENT TO OTHER VIN NUMBERS. I DRIVE CHILDREN AROUND IN THIS CAR, AND THIS ISSUE IS SEVERE AND SHOULD CLEARLY BE FOR A LARGER NUMBER OF CARS THAN THEY ARE ADMITTING. I HAVE NOW BEEN TOLD THAT THEY WILL NOT PAY FOR THE $3,000 IN REPAIRS BECAUSE IT IS NOT INCLUDED. THIS IS UNACCEPTABLE. THIS IS A SAFETY HAZARD ON THE ROAD AND UNBELIEVABLE THAT I WOULD PAY EXTRA MONEY FOR A TOYOTA BECAUSE IT IS SUPPOSED TO BE A SAFE AND RELIABLE CAR, ONLY TO FIND OUT THEY WILL NOT ADMIT WHEN THEY HAVE A WIDESPREAD BREAK MANUFACTURING ISSUE WITH THEIR VEHICLES. MY ONLY RECOURSE THOUGH TOYOTA I AM TOLD IS TO MAKE A CASE NUMBER AND IF MY VIN HAPPENS TO BE ADDED TO THE LIST, THEY MAY REIMBURSE ME. THIS IS UNACCEPTABLE. TOYOTA NEEDS TO RECALL ALL VINS FOR THIS ISSUE, SO CONSUMERS ARE AWARE THAT THEIR BREAKS MAY FAIL AT ANY MOMENT.

11/15/19 ORIGINALLY THE CAR SHOWED BRAKE, ABS, ANTISKID AND ENGINE IDIOT LIGHTS WENT TO THE DEALER WITH A CODE C1391. THEY SAID I NEED TO REPLACE THE MASTER CYLINDER AND THE POWER BOOSTER FOR $2600. THEN THEY SAID IT WAS POLICY TO ALSO REPLACE THE BRAKE BOOSTER PUMP ASSEMBLY FOR AN ADDITIONAL $2,000 OR A TOTAL OF $4600. AFTER I COMPLAINED THAT THEY HAD RECALLED 972,000 OTHER PRIUS BUT DIDN'T INCLUDE THE PRIUS V THEY SAID I ONLY NEEDED TO REPLACE THE MASTER CYLINDER AND POWER BOOSTER AND SAID THEY WOULD DO IT FOR $1,516.89. SO THEN I GO TO TAKE THE CAR TO THE SERVICE DEPARTMENT TODAY 12/4/19 AND WHILE SITTING THERE THE IDIOT LIGHTS ALL TURN OFF AND THE BRAKE START TO FUNCTION NORMALLY OWN ITS OWN... I ASK THE SERVICE REPRESENTATIVE WHAT HIS THOUGHTS WERE AND HE SAID I SHOULD STILL MAKE THE REPAIRS, BUT HE COULDN'T SAY WHAT THEY WOULD DO IT CAME BACK. SO I'M GOING TO DRIVE THE CAR FOR A WEEK TO SEE. WHILE I'M WAITING CAN YOU PLEASE DO A RECALL ON THE BRAKE PUMP ASSEMEBLY SINCE THESE FOLKS DONT EVEN KNOW WHAT THE HECK IS GOING ON WITH THIS CAR. IT APPEARS ITS NOT EITHER DEVICE AND ITS A COMPUTER GLITCH THAT THEY HAVEN'T RESOLVED...HELP US PRIUS OWNERS PLEASE!!!

MY 2012 PRIUS V STARTED SHOWING THE WARNING LIGHTS FOR BRAKES, ABS, ANTI-SKID AND ENGINE LIGHTS. THIS HAPPENED WHILE DRIVING ON A REGULAR ROAD. BRAKES STILL WORK BUT FEEL SPONGY. SCANNED FOR CODES AND IT SAYS C1391 WHICH REQUIRES REPLACING ALL THE MAIN BRAKE COMPONENTS. THE COST IS OVER $3000 BECAUSE SO MANY PARTS INVOLVED. THERE'S SEEMS TO HAVE BEEN A RECALL FOR OTHER MODELS OF PRIUS BUT THE 'V' NOT INCLUDED. MANY V OWNERS HAVE EXPERIENCED THIS PROBLEM. ALL THE PARTS SHOWN IN THE ATTACHED PICTURE NEED TO BE REPLACE CAUSE TOYOTA DOESN'T KNOW OR CAN'T FIGURE OUT WHERE THE PROBLEM IS. CAR ONLY HAS 68,000 MILES ON IT

NHTSA ODI 11280705

THE BRAKE LOSES ITS GRIP OVER A ROUGH ROAD BUMP WHILE PULLING IN FOR A STOP. VERY VERY NOT SAFE, I ALMOST REAR ENDED A CAR IN FRONT OF ME A COUPLE OF TIMES. CREATES EXTREMELY UNSAFE FEELING. BRAKE LOSS HAPPENS ALL THE TIME OVER BUMPY ROAD ONLY.

NHTSA ODI 11280476

MORE THAN ONCE I WAS DRIVING ABOUT 40/45MPH, ONCE ON A CURVE, ANYHOW AS I WAS GOING THROUGH THE CURVE IT FELT AS THOUGH THE BRAKES ENGAGED, WITHOUT ME TOUCHING THEM. I UNDERSTAND THE SAFETY THING, HOWEVER AT BOTH INSTANCES IT WAS NOT NECESSARY. IT CAUSED THE CAR TO PULL TO THE LEFT. ALMOST CAUSING ME TO LOOSE CONTROL.

NHTSA ODI 11279410

THE BRAKES FAILED WHILE DRIVING. ALL THE ABS, BRAKE LIGHTS AND A CONTINUOUS BEEP SOUND TURNED ON. I ALMOST HAD A CRASH. IT WAS THE BRAKE ACTUATOR PUMP AND I READ ABOUT MULTIPLE OWNERS HAD COMPLAINS WITH IT.

MY 2012 PRIUS V IS ONLY 90K MILES. STARTING FROM ABOUT 2 WEEKS AGO, THE WARNING LIGHTS INCLUDING BRAKE SYSTEM WARNING LIGHT, ABS WARNING LIGHT AND SLIP INDICATOR LIGHT WERE SUDDENLY LIT ON WHEN I WAS DRIVING, THEN I FOUND THE REGENERATE BRAKE BECOME VERY HARD AND DIFFICULT TO STOP WHICH WAS MALFUNCTIONING. THESE WARNING LIGHTS WERE KEPT ON ALL THE TIME WHEN I DRIVE THE CAR. THE CAR THREW OUT CODE C1391 WHEN GIVEN A DIAGNOSIS. AFTER SOME ONLINE WORK, I FOUND THIS IS A VERY COMMON PROBLEM FOR PRIUS V. I WENT TO THE DEALERSHIP HOWEVER THE DEALERSHIP STATES THAT MY CAR, BASED ON ITS VIN, IS NOT IN ONE OF THE CERTAIN CARS COVERED BY ZJB PHASE 2 WHICH COVERS BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLIES FOR CERTAIN 2011-2015 MODEL YEAR PRIUS VEHICLES. THE FAILURE OF THE BRAKE COULD BE A DEADLY DEFICIENCY TO ALL THE PEOPLE IN THE CAR WHEN DRIVING. NOW I HAVE TO THINK TO STOP USING THIS CAR BECAUSE OF THE SEVERE SECURITY RISK. TOYOTA SHOULD TAKE ACTION TO SOLVE ALL THIS PROBLEM FOR ALL INVOLVED CARS, NOT CERTAIN CARS. MY CAR IS MADE IN 2012, THE DIAGNOSIS CODE C1391 GIVEN BY MY CAR ARE FALLING INTO ONE OF THE FOUR CODES ASSOCIATED WITH THE BRAKE PROBLEM COVERED BY ZJB PHASE 2. IT IS RIDICULOUS THAT MY CAR WAS NOT ISSUED THIS EXTENDED WARRANTY.

MY 2012 PRIUS V WITH ONLY 55,000 MILES. ABS LIGHTS CAME ON AND BUZZING SOUND EVERY 3 SECONDS FROM JUST IN FRONT OF STEERING COLUMN. TOYOTA DEALER CHARGED $270 FOR COMPUTER DIAGNOSTIC THEN GAVE ME A PARTS AND LABOR ESTIMATE FOR REPLACING BRAKE BOOSTER AND MASTER CYLINDER OF $4400!!! INDEPENDENT MECHANIC CAN ORDER PARTS FROM ANOTHER TOYOTA DEALER IN MAINLAND US FOR $1400 LESS THAN THE $3200 THAT DEALER IN HAWAII QUOTED AND LABOR FOR MUCH LESS. BUT STILL WILL BE COSTING ME ABOUT $2500. SEARCHED RECALL SITES AND REGULAR 2012 PRIUS MODELS HAD RECALLS FOR EXACTLY THE SAME ISSUE BUT NO RECALL ON 2012 PRIUS V BRAKES?

NHTSA ODI 11268982

I STARTED MY CAR AND MY DASH LIGHTS FOR BRAKES, ANTI-LOCK, ANTI-SKID CAME ON AND BRAKES BECAME SPONGY. THIS HAPPENS INTERMITTENTLY. I PARKED THE CAR AND LATER CHECKED THE LIGHTS AND THE CAR WAS OPERATING NORMAL. I DROVE THE CAR AROUND THE NEIGHBORHOOD TO TRY TO DUPLICATE THE ISSUE. COULD NOT DUPLICATE. THE NEXT DAY I STARTED THE CAR THE LIGHTS CAME ON AGAIN AND BRAKES WERE NOT OPERATING NORMALLY. SPONGY AND NO ANTI-LOCK. I CHECKED RECALLS AND FOUND THE ISSUE WAS RECALLED IN 2010. I ALSO FOUND NUMEROUS COMPLAINTS ON PRIUS FORUMS FOR THIS ISSUE COVERING 2012 PRIUS. I THINK THIS IS A SAFETY ISSUE TOYOTA SHOULD RECALL FOR 2012 AS WELL.

NHTSA ODI 11265578

CAR WAS IN MOTION AND BRAKE PEDAL WENT HALF WAY TO FLOOR AND ABS, BRAKE, TRACTION CONTROL AND TIRE SENSOR LIGHTS CAME ON. MASTER CYLINDER OR BRAKE BOOSTER SEEM TO HAVE FAILED. DEALER DIDN'T RECOGNIZE CODES AND COULD ONLY RECOMMEND CHANGING SPARK PLUGS WHEN I JUST HAD THEM REPLACE 6-8 MONTHS PRIOR. EXPLAINED THAT DID THINK THAT HAD ANYTHING TO DO WITH BRAKES GIVING OUT. THEY RESET CODES AND SURE ENOUGH HAPPENED AGAIN WITHIN THE NEXT 30 DAYS. TOYOTA ADMITTED TO SINCE RECEIVING MANY REPORTS OF CERTAIN INTERNAL MALFUNCTIONS OF BRAKE BOOSTER ASSEMBLIES. 4 TRIPS LATER TO DEALER THE RESPONSE IS THE CODES ARE NOT COMING UP (DTCS) C1391, C1252, C1256 OR C1253 IN ORDER TO BE COVERED IT'S VOLUNTARY CUSTOMER SUPPORT PROGRAM WHICH HAS BRAKE BOOSTER AND BRAKE BOOSTER PUMP COVERAGE. VERY FRUSTRATING!

NHTSA ODI 11253950

MY CAR HAS THE SAME BRAKE BOOSTER/MASTER CYLINDER DEFECT THAT THE 2010/11 MODEL PRIUS WERE RECALLED FOR. BRAKE BOOSTER OR BRAKE PRESSURE ACCUMULATOR FAILURE ON 2012 MODELS CAUSES LOSS OF BRAKING EFFECTIVENESS. SERIOUS SAFETY ISSUE THAT CAN CAUSE DEATH. TOYOTA IS WELL AWARE OF THIS. THIS HAPPENS IN MOTION AT HIGHWAY SPEEDS.

NHTSA ODI 11253725

MY 2012 TOYOTA PRIUS II THREW ERROR CODE C1391 ABNORMAL LEAK IN ACCUMULATOR. I'VE RESET IT AND ITS COME BACK ON AGAIN. REGENERATIVE BRAKING HAS GONE OUT AND STOPPING IS DIFFICULT. THIS IS NOT RIGHT. MY CAR HAS JUST OVER 130,000 MILES

NHTSA ODI 11242127

COMPLETE BRAKE FAILURE ON THE FREEWAY!!! ABS, BRAKE AND TRACTION CONTROL LIGHTS LIT UP. ALMOST CRASHED! CODE C1391-ABNORMAL LEAK IN BRAKE ACTUATOR PUMP. HOW LONG WILL IT TAKE THIS AGENCY TO MAKE TOYOTA FIX THIS?? ITS A SAFETY ISSUE!!! STOP PICKING YOUR ASSES AND DO SOMETHING ABOUT IT!!!!

NHTSA ODI 11235210

VSA, AVS, AND BRAKE LIGHTS ON WITH DECREASED RESISTANCE IN PETAL. BRAKES WILL RETURN TO NORMAL WITHOUT WARNING PERIODICALLY WHILE DRIVING. THIS MAKES DRIVING AND STOPPING UNSAFE AND UNPREDICTABLE.

NHTSA ODI 11231596

TRACTION, BRAKE AND ABS LIGHTS ALL CAME ON AT ONCE, PRATICALLY LOST ALL BRAKING WHILE DRIVING BUT ABLE TO SLOWLY STOP. SQUISHY BRAKES. "PUMP" SOUNDING NOISE LIKE IT'S HAVING TROUBLE PUMPING BRAKE FLUID.

NHTSA ODI 11207636

I HAVING A PROBLEM WITH THE BRAKE BOOSTER ON MY PRIUS AND THE TOYOTA DEALERSHIP I WENT TO SAID I NEED TO REPLACE BOTH THE MASTER CYLINDER AND BOOSTER PUMP WHICH WOULD BE 3000 DOLLARS WORTH OF PARTS AND LABOR. AFTER RESEARCH THIS ISSUE I HAVE FOUND SERVAL PEOPLE HAVE THE SAME ISSUE. ALSO THE PARTS ARE ON BACK ORDER, SHOWING YOU HOW BIG OF ISSUE THIS IS. THE BREAKING SYSTEM FELT SPONGY, MY TRACTION CONTROL BRAKING SYSTEM AND ABS LIGHTS CAME ON. THANKFULLY I HAD JUST A COUPLE OF FEET TO MY DRIVEWAY.

NHTSA ODI 11203834

CAR EXPERIENCED GREATLY DIMINISHED BRAKING POWER ON INTERSTATE 75 PRIOR TO APPROACHING HEAVY TRAFFIC BACKED UP TO EXIT. MANY WARNING LIGHTS ILLUMINATED ON THE DASH: BRAKE, ABS, ETC. TOYOTA HAS ALREADY ISSUED A WARRANTY EXTENSION FOR THIS ISSUE FOR THE STANDARD MODEL PRIUS, AND I BELIEVE THIS IS A SAFETY HAZARD ON THE PRIUS V WAGON AS WELL.

NHTSA ODI 11203591

WHEN THE BRAKES ARE APPLIED AND GOING OVER A ROUGH ROAD SURFACE, OR POTHOLE, THE BRAKE WARNING LIGHT APPEARS, AND THE BRAKES SUDDENLY STOP FUNCTIONING UNTIL BACK ON A SMOOTH ROAD SURFACE. THIS HAPPENS ALL OF THE TIME UNDER THESE CONDITIONS. IT IS REALLY SCARY WHEN THE VEHICLE SUDDENLY LOSES ALL BRAKING WHILE TRYING TO STOP. I HAVE A 2012 TOYOTA PRIUS AND A 2010 TOYOTA PRIUS. THEY BOTH HAVE THE SAME PROBLEM WITH THE ABS BRAKING SYSTEM. CANNOT UNDERSTAND WHY THIS IS NOT A FULL RECALL ON THIS POTENTIALLY DANGEROUS CONDITION.

NHTSA ODI 11193354

THE CAR HAS BEEN SUFFERING ALL OF THE BRAKE SYMPTOMS FOR THE RECALL OF THE 2010 PRIUS BRAKE BOOSTER SYSTEM. I'VE REPEATEDLY COMPLAINED ABOUT LOSING BRAKING POWER WHEN THE ABS LIGHT COMES ON WHEN I GO OVER UNEVEN SURFACES SUCH AS RAILROAD TRACKS OR A POTHOLE. THE BRAKES HAVE BENN FARTING FROM DAY ONE WHILE SITTING AT A LIGHT OR PARKED IF THE BRAKES ARE DEPRESSED AND THEN SLIGHTLY RELEASED. AND NOW TODAY THE ABS BRAKES ARE ON WITH THE BATTERY LIGHT AND THERE IS LIMITED BRAKING POWER. I HAVE TO PUSH ALMOST ALL THE WAY DOWN BEFORE THE BRAKE ENGAGES. TOYOTA TELLS ME I NEED TO REPLACE THE BRAKE BOOSTER SYSTEM FOR $3500 AND THERE ARE ONLY 70,000 MILES ON MY 2012 CAR. I FEEL MY BRAKES HAVE THE SAME ISSUES AS THE 2010 RECALL AND MORE YEARS INCLUDING MINE ARE AFFECTED AND SHOULD BE RECALLED.

NHTSA ODI 11182610

I WAS COMING UP THE FREEWAY OFF RAMP AND MY CAR JUST TURNED OFF I HAD NO BRAKING I HIT SIX OTHER CARS ROLLED OVER AND WAS SEVERLY IMJURED IN THE HOSPITAL FORR THREE DAYS

TAKATA RECALL. RIGHT AFTER RECALL NO 18V-684 UPDATE SYSTEM ON MY PRIUS AT LOCAL TOYOTA DEALER MY CAR BRAKES PEDAL BECOME VEIRD . WHEN I JUST START ON THE ENGINE THN START MOVING AND STOPING, THE BRAKE PEDAL IS REALLY UP AND NOT MOVING DOWN AND BRAKES CAR REALLY QUICK. AT THE SAME TIME WHEN I START DRIVING I HEAR THAT REAR WRITING BRAKES FOR ABOUT 1-2 MILES. THEN IT COME OFF AND BRAKE PEDAL GOES DOWN LITTLE BIT TO NORMAL POSITION AND WORKS GREAT. THIS IS HAPPEN EVERY TIME WHEN SHOT DOWN ENGINE AND START AGAIN TO GO SOMEWHERE. ITS REALLY DANGEROUS BACOUS THE POSITION OF BRAKE PEDAL SOMETIME UP SOMETIMES DOWN, CAN NOT PREDICT HOW SOON YOU CAN STOP WHEN ITS NEEDED. IT ALWAYS HAPPEN NOW WHEN I DRIVE IN MY CITY ROADS. I CAME BACK TO DEALER THAT DID UPDATE SYSTEM ON MY CAR, THEY SAID THAT I NEED TO PAY TO FIND OUT WHAT IS GOING ON WITH MY CAR, THEY WILL CHARGE ME EVEN IF THIS HAPPEN AFTER THEIRE RECALL UPDATE SYSTEM ON MY CAR. THIS IS HORRABLE.
