What 684 owners told NHTSA about the 2012 Toyota Prius C

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!!!

VEHICLE HAS BEEN CONSUMING OIL TO THE POINT WHERE THE VEHICLE NEEDS MONTHLY OIL CHANGES. WAS TOLD MANY TOYOTA PRIUS MODELS HAVE HAD AN OIL CONSUMPTION ISSUE AND THAT I SHOULD FILE A COMPLAINT.

THE ENGINE WENT STALLED IN THE MIDDLE OF THE HIGHWAY. LUCKY ENOUGH, I WAS ABLE TO STOP THE CAR SAFELY WITHOUT ANY COLLUSION. BROUGHT THE VEHICLE TO A MECHANIC AND DIAGNOSED WITH EXCESSIVE CONSUMPTION OF ENGINE OIL. THE ENGINE HAD CATASTROPHIC DAMAGE AND NEEDED A REPLACEMENT. I SPOKE TO PIERCEY TOYOTA SERVICE DIRECTOR KEN JOHNSON AND HE STATED THERE IS NO ACTIVE RECALL FOR THE VEHICLE AND DO NOT BELIEVE IT IS THE VEHICLE ISSUE. I DO NOT BELIEVE THAT IS THE CASE, FURTHER INVESTIGATION IS NEEDED TO PREVENT OTHER SAME MODEL DRIVERS FROM A DEADLY ENGINE STALLING CRASH.

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

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.

AFTER REPAIR OF STALLING ENGINE CONDITION: VSV VALVE REPLACED, A SOFTWARE UPDATE SUBSEQUENTLY WAS PERFORMED ON MY CAR (JOV RECALL). EVER SINCE THAT SOFTWARE UPDATE IT HASN'T BEEN SAFE TO DRIVE MY CAR : UNSAFE BREAKING, REALLY HARD BREAKING, ESPECIALLY ON HIGHWAYS AND UNTIMELY DASHBOARD LIGHTING RELATED TO TRAC/VSC, CHECK ENGINE AND HYBRID WARNING LIGHT

NHTSA ODI 11277943

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?

HEAD GASKET 77,000 MILES WITH THE HEAD GASKET ISSUE THE CAR ENGINE WAS SHAKING WHEN IT'S WARMING UP. THE CAR LOG SHOWED MISFIRES IN 1ST AND 4TH CYLINDERS.

ON 09/19/2019 KEY WEST TOYOTA COMPLETED THE TIRES CHANGE OF MY VEHICLE AS I REQUESTED. IN ADDITION, KEY WEST TOYOTA PERFORMED "107649 J0V RECALL J0V01B 0.70 UPDATE TO THE POWER MANAGEMENT ECU WITH NEW SOFTWARE" AS SHOWING ON THE INVOICE. THE FOLLOWING DAY, ON FRIDAY 09/20/2019, WHILE I WAS DRIVING THE VEHICLE LOST POWER AND STALLED IN THE MIDDLE OF THE TRAFFIC, PUTTING MY LIFE AND SAFETY AT RISK AND MY HEATH AND GENERAL WELL-BEING. I SENT BACK THE VEHICLE TO KEY WEST TOYOTA, AND SINCE THEN THE ISSUE IS UNRESOLVED, AND I AM NOT EVEN ABLE TO REACH ANYONE ON THE PHONE OR THROUGH THE EMAIL I SENT FROM KEY WEST TOYOTA WEBSITE "CONTACT US".

VEHICLE IS MANUFACTURED WITHOUT ANY REGARD FOR PREVENTING MICE FROM ENTERING THE PASSENGER INTERIOR--- AIR INTAKE VENT UNDER WINDSHIELD AND 2 REAR DECOMPRESSION VENTS LOCATED IN THE REAR CARGO COMPARTMENT ABOVE THE WHEEL WELLS ARE OPEN TO THE EXTERIOR ALLOWING UNIMPEDED ACCESS TO THE INTERIOR OF THE CAR. HAD MICE IN THIS CAR 2 WEEKS AFTER PURCHASE IN 2012 AND HAVE BEEN DEALING WITH THIS PROBLEM FOR 7 YEARS. JUST RECENTLY, HAD TOYOTA INSTALL 1/4" HARDWARE CLOTH OVER THESE 3 AREAS AND THIS SHOULD HELP SIGNIFICANTLY TO PREVENT ENTRY. ALL PREVENTATIVE MEASURES TO PREVENT MICE ENTRY HAVE BEEN DILIGENTLY TAKEN BY ME, WITHOUT SUCCESS. MICE CAN MAKE A PERSON VERY SICK. THEIR EXCREMENT CARRIES HANTAVIRUS..... AND THE MICE CARRY TICKS, WHICH CAN LEAD TO LYME DISEASE. SIMPLY MANUFACTURING THE CAR WITH THESE VENTS PROPERLY SCREENED WOULD GREATLY REDUCE THE CHANCE OF OCCUPANTS CONTRACTING A SERIOUS DISEASE.THE MICE ALSO DO A LOT OF DAMAGE TO THE CAR ITSELF, IN MY CAR THE DRIVER SEAT BELT WAS CHEWED, AND I HAVE HAD TO REPLACE THE CABIN AIR FILTER SEVERAL TIMES BECAUSE OF NESTING IN THIS COMPARTMENT(AFTER HAVING BEEN UNKNOWINGLY BREATHING THE MICE EXCREMENT AS THE AIR PASSES THROUGH THIS FILTER ON ITS' WAY TO THE INTERIOR. TOYOTA NEEDS TO BE PRESSURED BY YOUR AGENCY TO CORRECT THIS VERY SERIOUS HEALTH HAZARD THAT THEIR CAR IS PRESENTING. THEIR IS NO LEGITIMATE REASON FOR THIS SITUATION TO EXIST. THE COST TO TOYOTA WOULD BE NEGLIGIBLE.THE BENEFIT TO ALL PRIUS OWNERS WOULD BE VERY SIGNIFICANT, LIKELY PREVENTING MANY CASES OF DISEASE. PLEASE TAKE THIS SITUATION VERY SERIOUSLY, AS IS THE CASE. I ALSO WILL BE CALLING YOU TO DISCUSS THIS OVER THE PHONE. THANK YOU FOR YOUR HELP TO CORRECT THIS PROBLEM!

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.

ON JUNE 5TH, 2019, I TOOK MY CAR IN TO ROUND ROCK TOYOTA AND THEY PERFORMED THE 2018 TOYOTA PRIUS V RECALL FIX. SINCE THEN, MY MPG HAS GONE FROM AN AVERAGE OF 41 MILES PER GALLON, WHICH HAS STAYED CONSISTENT SINCE I PURCHASED THE CAR BRAND NEW IN JUNE 2012, DOWN TO 32 MPG. I TOOK THE CAR BACK TO ROUND ROCK TOYOTA FOR A DIAGNOSIS ON SEPT 30, 2019 AND THEY SAID THAT THEY CANNOT FIND ANYTHING WRONG, THERE ARE NO ERROR CODES, AND THAT MY NOW GREATLY REDUCED 32 MPG FELL WITHIN TOYOTA STANDARDS. I AM WRITING TO FILE A COMPLAINT THAT THEIR 2018 RECALL FOR THE TOYOTA PRIUS V HAS A PROBLEM AND NEEDS TO BE REVISITED OR THE VEHICLES SHOULD BE TAKEN OFF THE ROAD. I AM CO-FILING A COMPLAINT WITH THE EPA AS WELL.

THE BRAKE BOOSTER/ACCTUATOR HAS FAILED ON MY PRIUS AT ABOUT 76000 MILES AND I BOUGHT IT USED WITH 35000 MILES. I HAVE FOUND OUT THAT THIS HAS BEEN AN ISSUE WITH PRIUS VEHICLES SINCE 2006 AND ENHANCED WARRANTIES HAVE BEEN ISSUED ON MODELS FROM 2006 AS WELL AS 2010-2015. I HAVE TRIED TO CALL TOYOTA TO HAVE THEM FIX THE ISSUE BUT THEY SAY THAT MY VEHICLE ISNT COVERED UNDER THE WARRANTY FOR SOME REASON. WHAT THEY SAID WAS THAT MY PARTS MAKER WASNT COVERED UNDER THE WARRANTY BUT IF ITS A PROBLEM THAT HAS BEEN PREVELANT IN OTHER PRIUS VEHICLES, I DONT UNDERSTAND WHY THIS WOULDNT BE COVERED REGARDLESS OF WHO MADE THE PART. IT HAS AFFECTED MY BRAKING RANDOMLY AND HAS ALMOST CAUSED ME TO HAVE AN ACCIDENT A COUPLE TIMES ALREADY. WHEN DIAGNOSED I GOT ERROR CODE C1391 WHICH WAS COVERED UNDER THE WARRANTY ENHANCEMENT LETTER I FOUND YET TOYOTA WILL NOT FIX MY VEHICLE.

NHTSA ODI 11254879

TAKATA RECALL FROM THE DATE OF PURCHASE, VEHICLE PERFORMED UNPREDICTABLY. I TOOK MY CAR TO THE TOYOTA DEALERSHIP AND THEY FOUND THAT THE HYBRID BATTERY NEEDED TO BE REPLACED. WHEN I DRIVE 45 MPH, THE VEHICLE WILL STALL AND ALL INDICATOR ILLUMINATE ON THE INSTRUMENT PANEL. IN THE MIDDLE OF THE ROAD, THE CAR WILL STALL. TOYOTA DOES NOT STAND BY THEIR PRODUCT. MY CAR GOES COMPLETELY DEAD. EVERY WARNING LIGHT TURNS ON AND ITS BLINKING.

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!

I HAVE HAD TO REPLACE HEADLIGHT BULBS MULTIPLE TIMES IN THE PAST TWO YEARS. READING REPORTS, IT IS THE EXACT SAME ISSUE AS THE 2010 AND 2011 PRIUS OWNERS HAD. I AM NOW HAVING TO HAVE MY HEADLIGHT COVERS RESURFACED BECAUSE MY PASSENGER SIDE HEADLIGHT IS NOT AT ALL VISIBLE AT NIGHT. THE DEALERSHIP IS RECOMMENDING REPLACING THE COMPARTMENT WHERE THE BULB GOES.

NHTSA ODI 11253609

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

BOUGHT THIS CAR BRAND NEW IN 2012 AND HAVE ALWAYS PERFORMED MAINTENANCE ON TIME. BETWEEN THE LAST OIL CHANGE AND THIS OIL CHANGE THE PRIUS IS BURNING OIL AND I AM HAVING TO ADD AT LEAST TWO QUARTS OF OIL BEFORE IT IS BACK ON THE DIPSTICK. I AM NOTICING THIS IS A PROBLEM WITH THE 2010-2014 PRIUS AND THAT TOYOTA HAS DONE NOTHING TO SOLVE IT. I DO NOT WANT TO BE ON A LONG TRIP AND BURN THROUGH OIL AND LOCK MY ENGINE UP CAUSING HARM TO MYSELF OR OTHERS.

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

I'VE HAD TO REPLACE THE LIGHT BULB ON MY PASSENGER SIDE HEADLIGHT CONSTANTLY OVER THE PAST COUPLE OF MONTHS. I HEARD THAT THERE WAS A RECALL ON THE WIRING HARNESS OF THE 2012 REGULAR PRIUS AND I'M WONDERING IF THE ISSUE HAS BEEN LOOKED AT IN THE PRIUS C MODELS.

TL* THE CONTACT OWNS A 2012 TOYOTA PRIUS. WHILE DRIVING 20 MPH, THE VEHICLE BEGAN TO STALL AND A WARNING INDICATOR SIGNALED THE CONTACT TO PULL THE VEHICLE OVER. THE CONTACT WAS ABLE TO COAST THE VEHICLE INTO A PARKING SPACE. THE VEHICLE WAS TOWED TO MARIETTA TOYOTA (750 COBB PKWY S, MARIETTA, GA 30060, (470) 938-8436) WHERE IT WAS DIAGNOSED THAT THE HYBRID INVERTER NEEDED REPLACEMENT. THE VEHICLE WAS REPAIRED.
