2012 TOYOTA PRIUS V Complaints

1)INTERMITTENT REGEN BRAKING FAILURE CAUSING BRAKES TO BECOME MORE DIFFICULT TO PRESS THUS HARDER TO STOP THE CAR IN A TIMELY MANNER. USUALLY WHEN THERE IS STOP AND GO DRIVING WILL THE REGENERATIVE BRAKING FAIL. 2) CLOGGED EGR VALVE CAUSING A LOUD ENGINE KNOCK RESULTING IN A BLOWN HEAD GASKET.

BRAKE LIGHT/TSC LIGHT ON DASH WAS ON. THERE APPEARED TO BE NO DIFFERENCE IN DRIVE-ABILITY, BUT THERE WAS A HUMMING NOISE PRESENT AT IDLE AND 20-30 MPH. TOOK CAR TO DEALER 4/30/2019 FOR CHECK. COGGINS TOYOTA IN JACKSONVILLE, FL DETERMINED THE CAUSE WAS A, ABNORMAL LEAK IN THE ACCUMULATOR. THEY REPLACED THE BRAKE BOOSTER/MASTER CYLINDER ASSEMBLY. AFTER THE NEW EQUIPMENT WAS INSTALLED, THE TECHNICIAN NOTICED THE NEW PUMP ASSEMBLY HAD EXCESSIVE NOISE AND VIBRATION INTERNALLY SO ANOTHER REPLACEMENT PART WAS ORDERED. NEW PUMP ASSEMBLY BRAKE BOOSTER WAS INSTALLED AND CAR WAS PUT BACK IN SERVICE 5/19/2019. TOTAL COST OF THIS SERVICE WAS $2,745.11. WE LATER LEARNED THAT A CUSTOMER SUPPORT PROGRAM CSP ZJB WAS ISSUED BY TOYOTA FOR 'CERTAIN" 2010 PHD PRIUS, "CERTAIN" 2011-2015 PRIUS, AND "CERTAIN" 2012-2015 PHV PRIUS. AS PER THE CSP ZJB MAILING TO OUR RELATIVE WHO ALSO OWNS A PRIUS, THE PROBLEM WAS "WITH THE BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLIES". ACCORDING TO DIANNE, CUSTOMER SERVICE REP WITH TOYOTA, THESE VEHICLES INCLUDED IN THE CSP ZJB WERE PRODUCED BETWEEN OCTOBER 2010 TO NOVEMBER 2015 AND INCLUDED SOME 946,100 VEHICLES. MY VEHICLE WAS NOT INCLUDED IN THIS PROGRAM AS THE VIN NUMBER DID NOT MATCH THE AFFECTED VEHICLES. HOWEVER, WE HAD THE SAME PROBLEM WITH OUR VEHICLE THAT THE PROGRAM WAS INITIATED TO INCLUDE. UPON SUBMITTING A REQUEST FOR REIMBURSEMENT FROM TOYOTA FOR THE COST ASSOCIATED WITH REPAIRS, IT WAS REJECTED. WE BELIEVE THE PROBLEM FOR WHICH THE SERVICE PROGRAM WAS INITIATED IS THE SAME PROBLEM WE EXPERIENCED AND OUR VEHICLE VIN SHOULD BE ADDED BY TOYOTA TO THE LIST OF AFFECTED VEHICLES SO THAT IT BECOMES ELIGIBLE FOR EXPENSE REIMBURSEMENT.

THIS COMPLAINT IS FOR A 2012 PRIUS V THAT I'VE NOTIFIED MY LOCAL DEALER AND TOYOTA ABOUT A POSSIBLE SAFETY ISSUE RELATING TO THE BRAKE BOOSTER. THE PRIUS V IS CURRENTLY NOT INCLUDED IN THE ZJB CUSTOMER SUPPORT PROGRAM AND I BELIEVE IT SHOULD BE. BRAKE PEDAL FEELS VERY FIRM AND INCONSISTENT AND MUCH HARDER TO ACTIVATE THE BRAKES. THERE IS CONSTANT (EVERY FEW SECONDS) BRAKE BOOSTER ACTUATION/WHIRRING CONSISTENT WITH SYMPTOMS OF A LEAKING/DEFECTIVE BRAKE BOOSTER PER MY LOCAL DEALER. WARNING LIGHTS FOR BRAKE, ABS, STABILITY CONTROL, AND TIRE PRESSURE ARE ON.

FAULTY HEAD GASKET, ENGINE SHAKING ON STARTUP, COOLANT DRAINING PREMATURELY, WHITE EXHAUST, LOW COMPRESSION AND POWER.

BROUGHT CAR IN FOR RECALL J0V00D AND IMMEDIATELY AFTERWARDS THE ABS,TRACTION-CONTROL, BRAKE LIGHT CAME ON. THE LIGHTS WENT ON AND OFF AND THEN STAYED ON. WENT BACK TO DEALER AND WAS TOLD IT NEEDED A $3800.00 REPAIR. WAS TOLD THAT CERTAIN VIN NUMBERS WERE AFFECTED, BUT NOT MY VIN#. NOT SURE HOW THIS IS POSSIBLE SINCE I AM READING ALL OVER THE INTERNET THAT THIS IS A PROBLEM ON THIS YEAR CAR ALSO? I WAS DRIVING ON HIGHWAY US 19 IN CLEARWATER, WHEN THIS ALL HAPPENED.

UNLIKE OTHER 2011-2015 TOYOTA PRIUS VEHICLES THE PRIUS V IS NOT COVERED UNDER TOYOTA'S CSP-ZJB CUSTOMER SUPPORT PROGRAM. MY 2012 PRIUS V HAS ALL THE INDICATIONS OF THIS BRAKE BOOSTER AND PUMP PROBLEM... MULTIPLE LIGHTS ON THE DASH (BRAKE, ABS, PCS ..... ON; CODES C1252 & C1256; AND BRAKE BOOST PUMP RUNNING EVERY 6-8 SECONDS PLUS A BRAKE PEDAL THAT YOU CAN PUSH TO THE FLOOR IN 4-5 SECONDS. IN HARD BRAKING I'VE HAD TO PUMP THE BRAKE PEDAL TO GET STOPPED. IT'S MY WIFE'S CAR BUT SHE WILL NOT DRIVE IT ANYMORE. TOOK THE CAR TO A TOYOTA DEALER WHO WAS AWARE OF THIS PROBLEM AND STARTED TO HAVE IT FIXED AT THEIR EXPENSE UNTIL HE PUT THE VIN # IN HIS COMPUTER. HIS ESTIMATE WAS $2500+ TO HAVE THE PROBLEM FIXED AFTER I PAID TO HAVE THE PROBLEM DIAGNOSED EVEN THOUGH HE KNEW WHAT THE PROBLEM WAS. I DECLINED AND CALLED TOYOTA CUSTOMER SERVICE WHICH WAS A WASTE OF TIME...SORRY, YOUR CAR IS OUT OF WARRANTY AND YOUR CAR DOES NOT HAVE A PROBLEM WE WILL COVER. ON THE NET, THERE ARE MULTIPLE PRIUS V OWNERS WITH THE SAME PROBLEM THAT STARTED IN 2008. UNTIL SOMEONE WITH A BIGGER STICK (NHTSA), TOYOTA IS SAYING THERE ISNOT A PROBLEM WITH THE PRIUS V BRAKES.

WHILE DRIVING THE BRAKES WENT OUT. I BROUGHT THE CAR TO TOYOTA AND THEY SAID THE BRAKE BOOSTER IS DEFECTIVE AND NEEDS TO BE REPLACED THE PRICE TO DO SO IS ABOUT $3,000 THEY ALSO SAID THEY DON'T KNOW WHY THIS HAPPENED AS IN SOME CASES YOU NEVER HAVE TO REPLACE A BRAKE BOOSTER NOR MASTER CYLINDER

2012 PRIUS V 68,000 MILES ON VEHICLE BRAKE ISSUES FROM THE TIME CAR WAS PURCHASED NEW FROM A TOYOTA DEALER. HISTORY... WHEN BRAKING AND GOING OVER ROUGH SURFACE OR BUMP, THE BRAKES WOULD SEEM TO MOMENTARILY DISENGAGE AND THEN REENGAGE AFTER THE SURFACE SMOOTHED. THE CAR SEEMED TO LUNGE OR SKIP FORWARD AND TAKE LONGER TO STOP. ALERTED THE DEALERSHIP, THEY CHECKED AND SAID EVERYTHING WAS FINE. THIS HAS CONTINUED THROUGHOUT MY OWNERSHIP OF THIS VEHICLE. RECENTLY DURING AN EMERGENCY STOPPING ACTION ON A FREEWAY, MY PRIUS WAS THE 3RD CAR IN A 3 CAR ACCIDENT. THE 1ST CAR FOR SOME REASON, SLOWED DRASTICALLY,AND WAS REAR ENDED BY THE CAR IN FRONT OF ME. I FELT I WAS AT A GOOD DISTANCE BEHIND THE CAR IN FRONT OF ME AND I REACTED AND FULLY DEPRESSED THE BRAKES AND FELT THIS CAR CONTINUE TO ROLL AND CONTACT THE CAR IN FRONT. THE BRAKES DID FINALLY TAKE HOLD, BUT I FELT A HESITATION WHICH LENGTHENED THE STOPPING DISTANCE. I HAVE RESEARCHED AND FOUND THERE ARE DOZENS OF REPORTED ISSUES WITH THE HYBRID'S BRAKE SYSTEMS IN BOTH PRIUS MODELS AS WELL AS SOME REPORTED ISSUES WITH LEXUS HYBRIDS. I WONDER HOW MANY OTHER INCIDENTS HAVE OCCURRED WITH THE MILLIONS OF PRIUS VEHICLES THAT HAVE NOT BEEN REPORTED. THERE SEEMS TO BE ISSUES WITH THE COMPUTERIZED/MECHANICAL BRAKING INTEGRATION AND POSSIBLE ISSUES WITH THE ACTUATOR.

IT STARTED WITH SHAKING ON STARTUP, IDLE AND LOW SPEEDS. CHECK ENGINE LIGHT CAME ON. DIAGNOSED WITH MULTIPLE CYLINDER MISFIRE. IGNITION COILS REPLACED, BUT DID NOT SOLVE THE PROBLEM. SUBSEQUENT ANALYSIS INDICATED COOLANT IN THE COMBUSTION CHAMBER DUE TO A FAILED HEAD GASKET.

OWNER/DRIVER FOUND BLACKED OUT BEHIND WHEEL IN 55 MPH HIGHWAY IN OPPOSING TRAFFIC DITCH. DRIVER AMBULANCED TO HOSPITAL ER. DMV REQUIRES MEDICAL EVALUATION FOR CONTINUED DRIVING PRIVILEGES. DRIVER SUSPECTED CARBON MONOXIDE POISONING. SUBSEQUENTLY, DRIVER PLACES RESIDENTIAL CARBON MONOXIDE DETECTOR INSIDE PRIUS WHICH ALARMED WHILE PARKED AND TURNED OFF AT RESIDENCE DRIVEWAY. TOYOTA CUSTOMER EXPERIENCE CENTER ISSUED CASE # [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
