2010 Toyota Prius Engine

TWO OCCURRENCES. WAS DRIVING 65 MPH WHEN SUDDENLY CAR BEGAN TO LOSE POWER. WAS UNABLE TO REGAIN ANY POWER BUT WAS ABLE TO COAST TO STOP ON SHOULDER. PRESSED THE ON/OFF BUTTON TO OFF. WAITED A FEW SECONDS AND PUSHED IT ON. WAS THEN ABLE TO DRIVE AGAIN. HOWEVER ABOUT 3 MILES LATER AT 25 MPH THE SAME THING HAPPENED. BOTH SITUATIONS OCCURRED DURING A TURN WITH AN UPHILL GRADE. FIRST TIME THE GRADE CHANGE WAS V.GRADUAL THE SECOND TIME MUCH MORE ABRUPT. NO SUCH PROBLEMS THE PREVIOUS YEAR WE HAVE OWNED THE CAR. DEALER SAID NO CODES WERE FOUND DURING A SCAN. *TR

2010 PRIUS 2. MULTIPLE OCCASIONS OF COMPLETE LOSS OF ENGINE POWER AND STALLING AT VARIOUS SPEEDS. COASTED TO THE SIDE OF THE ROAD AND RESTARTED/REBOOTED CAR. ALL INTERIOR LIGHTS STAYED ON BUT THE ENGINE WAS OFF. DEALER COULD NOT REPLICATE THE PROBLEM AND COULD FIND NO FAULTS. *TR

AROUND 4PM ON THU JAN 2ND 2014, WE WERE DRIVING EASTBOUND ON BEL-RED RD JUST ABOUT TO COME TO THE INTERSECTION OF NE 116TH ST WHEN I NOTICED THE ABS LIT UP, ALONG WITH THAT A WHOLE BUNCH OF OTHER LIGHTS LIT UP ON THE DASHBOARD AND I LOST POWER TO THE CAR (NO ACCELERATOR/BRAKE/STEERING). ALL ELECTRICALS SEEMED TO WORK. I TRIED TO POWER DOWN AND RESTART THE CAR. I CALLED TOYOTA OF KIRKLAND AND CHECKED IF THEY HAD A TOWING SERVICE, THEY DIDN'T. A COP OFFERED TO CALL A TOWING SERVICE. THE TOW TRUCK CAME BY AND HE AGREED TO GIVE ME A RIDE TO TOYOTA OF KIRKLAND AS WELL. AT THE DEALERSHIP, THEY JUST DID THE PAPERWORK AND SAID THEY'D CALL TOMORROW. FRIDAY JAN 3RD 2014 I WAITED UNTIL 11:15AM. NO CALL FROM TOYOTA OF KIRKLAND. I CALLED THEM. I SPECIFICALLY ASKED FOR THE ERROR CODES. HE CALLED BACK A LITTLE WHILE LATER AND SAID THAT IT LOOKED LIKE THE INVERTER WAS FAULTY. THIS WOULD BE COVERED UNDER THE DRIVE TRAIN WARRANTY WHICH WAS FOR 3 YEARS OR 36,000 MILES WHICHEVER CAME FIRST. SO, I WOULD BE LOOKING AT PAYING ABOUT $3300 FOR THE PART, $300 FOR LABOR, $110 FOR THE DIAGNOSTIC TEST AND TAXES. THEY COULD GET THE PART IN TOMORROW AND POTENTIALLY HAVE IT FIXED SAT OR LATEST MONDAY. THE ERROR CODES WERE P0A94 & P324E I LOOKED UP ONLINE FOR THESE ERROR CODES. THERE WERE SOME OTHER COMPLAINTS THAT WERE VERY SIMILAR TO THE ONE I HAD AND THE PROBLEM WAS THE INVERTER. AND IT ALSO SEEMED THAT THERE WAS A RECALL ON THE INVERTER (OR PARTS) FOR THE MODELS FROM 2005-2009. SO, CALLED 1-800-331-4331 (TOYOTA CUSTOMER SOMETHING). SHE TOOK DOWN ALL THE DETAILS. WHILE SHE PUT ME ON HOLD TO LOOK UP THE WARRANTY INFORMATION, TOYOTA OF KIRKLAND CALLED AND LEFT A MESSAGE SAYING THAT HE HAD MISUNDERSTOOD THE WARRANTY AND THAT IT WAS ALL COVERED AND HE COULD ORDER THE PART IN, IT WOULD BE THERE TOMORROW (SAT) AND THE CAR WOULD BE READY MONDAY!

DRIVING ON FREEWAY AND CAR OVERHEATED. THERE WAS NEVER ANY WARNINGS OF OVERHEATING PROBLEMS BEFORE. PULLED OVER ON FREEWAY AND HAD CAR TOWED TO AUTO SERVICE. WATER-PUMP WAS NOT WORKING, FAN STOPPED TURNING, COST TO REPLACE WAS $1260, TOYOTA WOULD NOT HELP AS CAR WAS OUT OF WARRANTY. *TR

I WAS DRIVING ABOUT 55 MPH WITH HEAT ON AND ALL A SUDDEN CHECK ENGINE LIGHT CAME ON AND THE ALL LIGHTS IN DASH BOARD CAME ONE WITH CHECK HYBRID SYSTEM SIGN AND ENGINE LOST POWER AND CAME TO COMPLETE STOP I PULLED OVER AND WAITED FEW MINUTES AFTER IT WAS FINE BUT WHEN EVER I TURN HEAT OR AC ON IT DOES THE SAME I DID MY RESEARCH IT LOOK LIKE INVERTER ISSUE OR THEY HAVE SOME CODE IN THERE SOFTWARE BECAUSE WE BOUGHT 2 CAR PRETTY MUCH SAME TIME AND BOTH HAS SAME PROBLEM SAME TIME AND THIS YEAR BOTH CARS HAD HYBRID BATTERY ISSUE WITH BOTH CAR SAME TIME TOYOTA SEND LETTERS TO 2013 AND 2014 PRIUS OWNER IF THEY EXPERIENCE SAME ISSUE ITS COVERED UNDER WARRANTY BUT WE HAVE SAME ISSUE BUT THEY DIDN'T ADDRESS IT MEANS THEY KNOW. *TR

IN THE LAST YEAR OR SO, MOST NOTICEABLY RANGING 50K MILEAGE, I'VE STARTED FALLING ASLEEP AT THE WHEEL. I'VE NEVER FALLEN ASLEEP DRIVING NOR HAVE I FELT THIS WAY WHILE OPERATING ANY OF THE 4 VEHICLES I'VE OWNED. IT HAPPENS DURING MY COMMUTE TO/FRO WORK GENERALLY 40-70 MINUTES LONG, LONG AND SHORT DRIVES BUT MORE OFTEN ON COMMUTE AND 30 MIN OR LONGER TRIPS. ITS AT RANDOM AND I'VE ANALYZED ITS NOT THE BASIC AND OBVIOUS ISSUES CAUSING IT; LACK OF SLEEP, FOOD, ADEQUATE HYDRATION ETC. IT GOT SO BAD I COULD NOT DRIVE TO WORK IN THE MORNING OR EVENINGS WITHOUT PULLING OVER AND TAKING A 20 MINUTE NAP. SOMETIMES ITS WORSE THAN OTHER TIMES AND IT FEELS LIKE I'M PASSING OUT, NOT QUITE TIRED AND DROWSY, I AM ALL-OUT CAN'T KEEP MY EYES OPEN, ROLLING EYES, HEAD BOBBING. EVENTUALLY WHEN I MAKE IT HOME SAFE, THINKING I'LL GO TO BED RIGHT AWAY I AM ALERT AND ACTIVE ALL NIGHT - THIS IS THE BEHAVIOR OVER AND OVER. I'VE DISCUSSED WITH THE DOCTOR AS WELL AND I'VE BEEN GENERALLY FATIGUED FOR A FEW YEARS NOW, I'VE OWNED THE PRIUS SINCE 2011. SOMEONE SAID ONLINE IN A FORUM "ITS A COMMON OCCURRENCE OF PEOPLE WHEN THEY'RE EXPOSED TO HIGH LEVELS OF ELECTROMAGNETIC RADIATION TO FEEL EXTREMELY TIRED AND FATIGUED." BUT FOLKS SAY ITS NOT ENOUGH TO CAUSE THIS TYPE OF BEHAVIOR. ANOTHER USER ALSO MENTIONS FALLING ASLEEP IN THIS FORUM (JUNE 5TH 2013) AND THERE'S BEEN OTHER NOTATIONS ON THE INTERNET, FOR EXAMPLE HTTP://PRIUSCHAT.COM/THREADS/PRIUS-EMF-RADIATION-AND-TOYOTAS-BOLD-FACE.116044/PAGE-6#IXZZ2VYI4P2S7. *TR

DRIVING THE CAR AT 40 MPH WENT IT SUDDENLY STOPPED. WAS ABLE TO COAST TO THE SIDE OF THE ROAD. FOUND OUT TODAY THAT THE WATER PUMP CAUSED THE INVERTER TO BECOME NON-WORKING WHICH CAUSED THE ENGINE TO SHUT DOWN. VERY DANGEROUS. LUCKY I WAS NOT ON THE INTERSTATE. *TR

I HAVE A 2010 PRIUS VIN:[XXX] WITH 37,000 MILES. THE CAR EXPERIENCES RANDOM LOSSES OF POWER DURING WHICH THE ENGINE SHUTS DOWN AND DOES NOT ACTIVATE NO MATTER HOW HARD I PUMP THE ACCELERATOR. ONCE I TURN OFF AND PUSH AGAIN THE START BUTTON, THE ENGINE STARTS UP WITHOUT ANY PROBLEM AND I CAN CONTINUE ON MY WAY. I HAVE EXPERIENCED THIS PROBLEM 5 TIMES SINCE SEPTEMBER 2012. I HAVE TAKEN THE CAR IN TO THE DEALER (CALDWELL TOYOTA, NJ) WHERE IT WAS EXAMINED AND THEY TOLD ME THE ONBOARD COMPUTER DID NOT RECORD ANY MALFUNCTION. I AM GETTING WORRIED SINCE SOME OF THE POWER LOSSES HAPPENED WHEN I WAS ON HIGHWAYS AT SPEEDS OVER 60MPH AND I HAD TO COAST TO A STOP IN HIGH TRAFFIC AREAS. I WOULD LIKE TO KNOW WHETHER OTHER PRIUS OWNERS HAVE REPORTED SIMILAR PROBLEMS AND WHETHER YOU HAVE SUGGESTIONS ON HOW TO PROCEED [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

AT ABOUT 125,000 MILES, THE ENGINE WARNED ME OF LOW OIL. IT WAS THE FIRST SUCH WARNING EVER WITH THIS VEHICLE. AT THAT TIME I COULD SECURE ONLY 2 QUARTS OF THE REQUIRED SYNTHETIC OIL AND IT WAS STILL OVER 1 QUART LOW. ABOUT 500 MILES LATER I TOOK THE VEHICLE TO TOYOTA CHULA VISTA AND EXPLAINED. THEY ADDED 3 MORE QUARTS OF OIL AND SUGGESTED A SERIES OF OIL CONSUMPTION TESTS. I CALLED TOYOTA MOTOR USA CONSUMER RELATIONS AND OPENED A CASE INDICATING THAT I WAS CONSUMING (BURNING NOT DRIPPING) 1 TO 2 QUARTS PER 1,000 MILES AND MY MPG HAD DECREASED FROM 46 AVG TO 35 AVG. THE OIL CONSUMPTION OVER THE NEXT 3 MONTHS AVERAGED 1 QT/600 MILES AND MY AVG MPG DETERIORATED FURTHER TO 29 MPG. IN JULY TOYOTA CHULA VISTA PERFORMED A TEARDOWN AND ENDED UP REPLACING THE LOWER ENGINE, CYLINDERS RINGS, AND VALVES. I WAS INFORMED THAT OTHER 2010 TOYOTA PRIUS ENGINES EXHIBITED FAILURE/WEAR OF THE CYLINDER WALLS AT ABOUT THE SAME MILEAGE. FIELD TECHS WERE CONTACTED AGAIN BY THE CHULA VISTA SERVICE MGR AND I CONTACTED TOYOTA NATIONAL SEEKING SOME ASSISTANCE IN THE $6,400 REPAIR BILL. BOTH LOCAL FIELD REP AND NATIONAL DECLINED THOSE REQUESTS. WHAT GOOD IS A 10 YEAR HYBRID BATTERY WITH A 3 YEAR ENGINE? *TR

WHILE MAKING A U TURN THE VEHICLE LOST POWER AND THE CHECK HYBRID SYSTEM WARNING ILLUMINATED. THE CAR DIED IN THE MIDDLE OF THE ROAD. THE DEALER CLAIMED THAT THERE WAS OIL IN THE THROTTLE BODY CAUSED BY OVERFILLING AND THIS IS A COMMON OCCURRENCE WITH OIL OVERFILLS ON PRIUS VEHICLES. THE LAST OIL CHANGE HAD BEEN 8,000 MILES AND MORE THAN 2 MONTHS PREVIOUS. THE PLACE THAT PERFORMED THE OIL CHANGE AGREED TO LOOK AT CAR AND CLEAN THE THROTTLE BODY. THEY ALSO CHECKED THE OIL AND MADE SURE IT WAS CORRECT LEVEL. THREE WEEKS LATER THE SAME THING OCCURRED. THIS TIME THE CAR LOST POWER AND THE CHECK ENGINE LIGHT ILLUMINATED. THE CAR DIED ON A FREEWAY TRANSITION OVER PASS AND WE WERE STRANDED ON THE FREEWAY IN A VERY DANGEROUS SITUATION. THE CAR WAS TOWED TO ANOTHER TOYOTA DEALER AND THEY CLAIMED IT WAS THE SAME THING. THE OIL CHANGE PLACE SAYS ABSOLUTELY NO WAY IS THIS THE PROBLEM SINCE THEY LOOKED AT IT VERY CLOSELY THE LAST TIME. I REQUESTED TOYOTA TO SEND OUT A FIELD REPRESENTATIVE TO CONFIRM THAT THIS WAS THE CAUSE. THEY REFUSED. COMPUTER CODES P3190 AND P0A0F HV. *TR

DURING COLD TEMPERATURE STARTUPS THE ENGINE KNOCKS LOUDLY FOR ABOUT 7 SECONDS. THE PROBLEM HAPPENS ONLY DURING COLD TEMPERATURE. THIS HAS HAPPENED ABOUT FOUR TIMES. WENT TO DEALER AND THEY WERE NOT ABLE TO FIX OR FIND THE CAUSE. 2ND TRIP THEY REPLACED THE ENGINE MOUNT BUT THE PROBLEM IS STILL THERE. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE TRAVELING 40 MPH, THE CONTACT NOTICED A BEEPING SOUND COMING FROM THE VEHICLE FOLLOWED BY THE SEAT BELTS LOCKING. MOMENTS LATER, THE VEHICLE DECELERATED TO A COMPLETE STOP INDEPENDENTLY. THE CONTACT WAS ABLE TO RESUME NORMAL OPERATION. THE VEHICLE WAS NOT DIAGNOSED AND OR REPAIRED. THE CURRENT AND THE FAILURE MILEAGES WERE 35,643.

ENGINE KNOCKS UPON STARTING BUT GOES AWAY AFTER ABOUT 10 SECONDS. THE VEHICLE DOESN'T DO THIS VERY OFTEN AND IT IS DIFFICULT TO DUPLICATE. REFERENCE THIS YOUTUBE VIDEO FOR AN EXACT REPLICATION OF THE PROBLEM: HTTP://YOUTU.BE/TCBG97UBX5S. *TR

MY WIFE AND I OWN A 2010 TOYOTA'S PRIUS. ON THE MORNING OF DECEMBER 15, 2010, SHE WAS COASTING THE VEHICLE INTO A PARKING SPOT AT HER OFFICE IN RESTON, VA. THE ACCELERATOR WAS NOT DEPRESSED AND THE BRAKES WERE NOT APPLIED. AS SHE GOT INTO THE SPACE, THE GAS ENGINE ENGAGED, NOT UNCOMMON AT VARIOUS TIMES, AND THE VEHICLE SUDDENLY ACCELERATED OUT OF CONTROL STRIKING THE CURB AND SOME BUSHES. THE VEHICLE SUSTAINED ABOUT $400 IN BODY DAMAGE AND SHE WAS INJURED. SHE CALLED THE DEALER WHO IMMEDIATELY REFERRED THE ISSUE TO TOYOTA CORPORATE. AFTER 6 WEEKS OF WAITING FOR A DECISION, TOYOTA SAID IT'S NOT THEIR PROBLEM. THE DEALER REFUSES TO EXAMINE THE VEHICLE DUE TO TOYOTA?S RESTRICTIONS AND WE CANNOT EVEN PAY TO HAVE IT EXAMINED AT THAT DEALER OR ANY OTHER. WE ARE LOCKED OUT OF ANYTHING EXCEPT TAKING THE VEHICLE BACK. NO WARRANTY WORK, NO MAINTENANCE WORK. NOTHING. *LN

AFTER CAR SITS FOR SEVERAL DAYS ENGINE WILL IDLE VERY ROUGHLY UPON STARTING FOR ALMOST ONE MINUTE. IDLE IS SO ROUGH THAT I THOUGHT THE ENGINE MOUNTS WOULD BREAK AND CREATES A VERY 4 LOUD RATTLING SOUND. THIS HAS HAPPENED THREE TIMES, TWO AFTER SITTING FOR SEVERAL DAYS AND ONCE AFTER JUST SITTING OVERNIGHT. *TR

THE CAR WAS NOT USED FOR ABOUT 4 DAYS OR SO. WHEN I STARTED IT, IT EXHIBITED A "ROUGH ENGINE START" FOR THE FIRST TIME. THIS HAPPENED WHEN THE GAS ENGINE INITIATED AND LASTED FOR ABOUT 10 SECONDS. DURING THIS TIME THE ENGINE MADE A VERY LOUD NOISE AS IF THE CAR WAS CHOCKING AND ENGINE WANTED TO GET OUT OF THE CAR'S HOOD. THIS HAS HAPPENED ONLY ONCE. THE CAR STOPPED MAKING THE NOISE AFTER 10SECONDS OR SO. *TR

AFTER A ACCIDENT WHERE THE CAR ROLLED ON ITS SIDE, THE ENGINE WOULD NOT TURN OFF. *TR

ACCESS TO THE OIL DRAIN PLUG AND OIL FILTER IS THROUGH A PLASTIC DOORWAY OPENING UNDER THE ENGINE COMPARTMENT. THE DOORWAY IS A PARTIAL CUTOUT FROM A LARGER PLASTIC SHIELD WHICH ENCOMPASSES THE ENTIRE FRONT PORTION OF THE CAR. I PERFORMED MY 3RD OIL CHANGE AND DURING THIS PREPARATION I FOUND THAT THE DOOR PORTION OF THE SHIELD IS BROKEN AWAY FROM THE LARGER PIECE OF PLASTIC DUE TO BENDING/HINGING THE DOOR. ONLY AFTER 2 OIL CHANGES THIS PLASTIC DOOR HAS BROKEN OFF BECAUSE THE PLASTIC IS NOT DESIGNED TO BE REPEATEDLY BENT FROM OPEN TO CLOSE MORE THAN ONCE. UNLESS YOU CHANGE YOUR OWN OIL, YOU WILL NEVER SEE THIS DOOR BREAK OFF... AND AFTER 2 OIL CHANGES. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 25 MPH ON NORMAL ROAD CONDITIONS. THE DRIVER STRUCK A BUMP IN THE ROADWAY WHICH CAUSED THE ENGINE TO VIOLENTLY REV. HE APPLIED PRESSURE TO THE BRAKE PEDAL, AND HE RESUMED NORMAL VEHICLE OPERATION. AN AUTHORIZED DEALER WAS NOTIFIED OF THE MALFUNCTION IN WHICH THERE WAS NO RESOLUTION. THE FAILURE MILEAGE WAS 2,000. THE CURRENT MILEAGE WAS 2,700. UPDATED 01/15/10. *LJ UPDATED 01/19/10.*JB
