2011 TOYOTA PRIUS Engine Problems

The contact owns a 2011 Toyota Prius. The contact stated that while operating the vehicle, the check engine warning light remained illuminated, the vehicle had unexpectedly shut off. Additionally, the transmission failed to shift into the intended gear. The vehicle was towed to the local dealer who replaced the catalytic converter, but the failure persisted. The vehicle was towed back to the dealer who diagnosed that the inverter was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact was informed that the VIN was not included in the NHTSA Campaign Number: 14V053000 (HYBRID PROPULSION SYSTEM, ELECTRICAL SYSTEM). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 117,000.

In 11/2024, I started experiencing intermittent noises coming from the engine compartment of my 2011 Toyota Prius. The initial sound resembled the buzzing noise generated when first starting the vehicle. Then the noise started to persist for extended periods after the vehicle was turned off. It would oscillate between buzzing for approximately 10 seconds & remaining dormant for about 1 minute, repeating this cycle. The duration of these cycles could extend for up to 20 minutes. Concurrently, I experienced several instances where the brake pedal would abruptly become stiff & difficult to press. Notably, no warning lights were illuminated on the dashboard. Recognizing these symptoms as unusual, I conducted online research and discovered that the issue could potentially stem from a malfunction in the “brake booster pump and assembly.” Given the potential for a loss of braking power and the risk of personal/public safety, I scheduled a diagnostic inspection at Toyota of Poway, Poway, CA, on 12/18/2024. It confirmed the presence of a problem with the brake booster pump and associated components. In light of this diagnosis, I made the decision to refrain from driving the vehicle until the repairs were completed. The repair costs amounted to $3,475.47. I found I had received a notification from Toyota’s Customer Support Program, designated as “Customer Support Program Notification-ZJB.” This notification explicitly acknowledged this defect & provided a repair coverage policy that stipulated a coverage policy of which I’m no longer entitled to. Despite not meeting the eligibility criteria for the repair coverage program, I am deeply troubled by the fact that this recognized defect persists in vehicles currently on the road, such as mine, without any corresponding recall action and subsequent repair costs covered by Toyota. Fortunately, I was spared from any accidents as a direct consequence of this issue. Many similar complaints here support this dangerous issue!

The contact owns a 2011 Toyota Prius. The contact stated while driving approximately 35 MPH, the contact smelled an abnormal burning odor and then heard an abnormal explosion. The contact observed black smoke coming from under the hood. The contact pulled off the road and turned the vehicle off. The contact stated no warning light was illuminated. The contact lifted the hood and saw flames coming from under the engine. The contact was able to extinguish the fire with a fire extinguisher. The contact had the vehicle towed to his residence. The contact called an independent mechanic who diagnosed the vehicle and determined that the engine needed to be replaced. The contact stated that when the engine was lifted out of the engine compartment, there was a hole in the engine block. The vehicle was repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 150,000.

Mileage: 150,000

If I make a longer trip more than 10 to 15 miles the car does fine if I drive it 2 miles down the road or across the street to a different store the car tells me to check hybrid system. I had it check and code c1391 came up and that was repaired. Once repaired picked up from shop drove across the street to gas station and it told me to check hybrid system again and went into limp mode. Once I do a reset the car will start back up and drive fine as long as it's a long trip if I go on another short trip it will do it again.

The contact owns a 2011 Toyota Prius. The contact stated while driving at 60 MPH, the vehicle lost motive power and stopped in the middle of the road. There was no warning light illuminated. The vehicle failed to restart and was towed to an independent mechanic who informed the contact that they could not duplicate the failure. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 190,000.

one year after bought, was losing power, replacing a lot of batteries, headlights and lamps then car would lose power while driving, not start continually everyday for each day after and even started on its own. i took in a lot and they put my vin to the wrong person..someone rainsford so my service recs were not recorded. said no battery code, didnt check altenator, and even tho serv advisor said the break was squishy to him and he heard the loud buzz noise when pushing, it was not replaced. they tried to blame it on keys being in car which is how it starts and runs! not parked on hill or in bad temps and driven long trips, none of which SHOULD BE REQIRED to start a car to get to dying patients on time. we bought charger and use on both priuses daily. lost power while driving, got hurt, and josh's pt. died. nothing but headache nightmares. have long written records where submitted all and they just like to deny things or try to find a way to blame on consumer. my only fault was buying an undisclosed deathtrap. they need to refund us both cars and damages and expenses and our time and missed work. the shuttle was a joke. i have my own top notch code reader and it said battery was fine. it was new, yet they wanted to sell me one so they said it coded but refused to show me. they are just trying to make money and really hurting people. sending my title and all my personal info to a stranger and me catching after 7 years broght on an ID theft im still fighting. very rude front staff and drivers..sheldon.

THE CHECK ENGINE LIGHT IS ON; THE CAR HAS STALLED AND LOOSES POWER IT NEEDS TO HAVE THE STICKY EXHAUST GAS RECIRCULATION VALVE TAKEN CARE OF. IT ALSO NEEDS PSV COVERAGE FOR BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLY SAFETY WARRANTEE ENHANCEMENT

LOUD RATTLE, SHAKING IN MOTOR AREA. WAS FOUND TO BE A HEAD GASKET LEAK. USING A LOT OF ANTIFREEZE AND WHITE SMOKE OUT THE TAIL PIPE. WHILE IDLE OR IN MOTION AND WHILE GAS ENGINE IS RUNNING. STARTED INTERMITTENTLY AT FIRST AND VERY SHORT, EG. FOR A SECOND OR TWO, THEN GOT LOUDER, MORE OFTEN AND LASTED LONGER. THIS CAR HAS 128,000 MILES. THIS SAME ISSUE IS HAPPENING ON MY 2010 PRIUS WITH 250,000 MILES. I RESEARCHED THIS AND IT IS A COMMON PLACE WITH GEN 3 PRIUS CARS. I CAN NO LONGER DRIVE EITHER ONE OF MY PRIUS CARS SAFELY.

I WAS MAKING A LEFT TURN AT A VERY BUSY LOS ANGELES INTERSECTION AND DURING NEEDED ACCELERATION TO TURN, THE PRIUS LOST POWER FOR A FULL SECOND AND THEN POWER CAME BACK SLOWLY AND I BARELY MADE IT THROUGH THE INTERSECTION, A T BONE COLLISION WAS IMMINENT, AND I MISSED GETTING HIT BY INCHES. ALL THE WARNING LIGHTS ON THE DASH ILLUMINATED AND I WAS FRAZZLED. THE HYBRID BATTERY WAS 2/3 RDS FULL AT THE TIME. THERE HAVE BEEN OTHER INSTANCES WHERE THE CAR LOST POWER FOR BRIEF MOMENTS WHEN THE HYBRID BATTERY WAS LOW AND DIDNT THINK ANYTHING OF IT AT THE TIME. THE MPG HAS REMAINED BELOW 40 AND AFTER HYBRID FAILURE, AROUND 26. ALSO, I HAD A GEN 2 PRIUS AND THE CATALYTIC CONVERTER WENT BAD AROUND 150,000. CALIFORNIA PUNISHES CONSUMERS BY NOT ALLOWING AFTER MARKET CATS AND FORCES THEM TO BUY OEM AT AN EXTREME MARK UP. WITHOUT A PROPER CAT, YOU CANT HAVE CAL SMOG APPROVAL, NO APPROVAL, NO REGISTRATION. TOTAL WASTE OF RESOURCE WHEN THE ACTUAL COST OF REPLACEMENT OF THE CAT IS AROUND $2K AT THE DEALER. IF I LIVED IN AZ, AFTER MARKET IS $475. AT THAT POINT A CAR OF THAT AGE AND MILAGE IS WORTH AROUND $2-3K. BATTERY AND CAT REPLACEMENT COSTS SHOULD NOT ECLIPSE THE VALUE OF THE CAR. STILL DOESN'T MENTION THE REST OF THE MECHANICAL AND SAFTEY APPARATUS . IF AN ENGINE WORKS HALF TIME ON A HYBRID, WHY DOES THE CAT BURN OUT SO SOOOON? THE SCAM IS BAKED INTO THE VEHICLE AND OUR GOVT SUPPORTS IT. FIX CARB!

CAR STALLED PULLING INTO TRAFFIC. TOOK ABOUT 15 SEC TO RESTART. NO DIAGNOSTIC LIGHTS LIT UP ON DASH. CAR LOST POWER LAST MONTH AND ENGINE LIGHT WENT ON AND ENGINE COULD NOT BE RESTARTED.HAD TO BE TOWED TO DEALERSHIP. IT REPLACED VALVE ASSEMBLY FOR VACUUM AND REPROGRAMMED PCM. HOWEVER, THAT ISSUE WAS PRECEDED BY A CREEP OF DIAGNOSTIC LIGHTS (COURSE OF 1 HOUR), FROM CHECK OIL TO CHECK ENGINE, AND THEN IT COMPLETELY SHUT DOWN.

WHILE DRIVING AT CA FREEWAY SPEED (65MPH) THE CAR GOES LIMP. THE ACCELERATOR FAILS TO WORK AND EVEN FLOORING THE VEHICLE MAKES NO DIFFERENCE. AT THIS POINT THE SPEED OF THE VEHICLE DECREASES AND I HAVE TO IMMEDIATELY PULL TO THE SHOULDER. THE "CHECK HYBRID SYSTEM" ALERT SHOWS ON THE DASH AND ALSO ELECTRIC POWER STEERING AND CHECK ENGINE LIGHT. THIS ISSUE HAS BEEN GOING ON FOR THE PAST YEAR AND I HAVE TAKEN IT TO SEVERAL TOYOTA DEALERSHIPS WITH NO RESOLVE. I HAVE SPENT A TOTAL OF $4500 WITHOUT TOYOTA OF VALLEJO OR THE NOW BANKRUPT TOYOTA OF FAIRFIELD SOLVING THE ISSUE.

STARTING FROM A STOP AFTER ENGINE SHUT-DOWN, THE CAR FELT LIKE IT WAS GOING OVER RUMBLE STRIPS. THIS GOT WORSE OVER TIME UNTIL I REALIZED THAT IT WAS ACTUALLY AN ENGINE MIS-FIRE. THE DEALER TRACED THE ROOT CAUSE TO A LEAKING CYLINDER HEAD GASKET THAT IS A COMMON FAILURE ON HIGH MILEAGE 3RD GENERATION PRIUS CARS. $4,000 REPAIR. FIRST CAR I'VE EVER OWNED THAT CYLINDER HEAD GASKETS ARE ROUTINE MAINTENANCE ITEMS. CLEAR DESIGN ISSUE. IF YOU KEEP THIS CAR LONG ENOUGH, YOU WILL BE BUYING A HEAD GASKET REPAIR.

MY TOYOTA PRIUS LOSES POWER RANDOMLY AFTER HAVING THE RECALL FIX J0V COMPLETED UPDATING THE SOFTWARE IN INVERTER. VEHICLE STALLED 3 TIMES ON FREEWAY, HIGHWAY AND OFF RAMP. DASH BOARD LIGHTS LIGHT UP WITH ALL WARNING LIGHTS. VEHICLE LOSES POWER....CAN DRIVE A MILE OR SO WITH ALMOST NO POWER...THEN VEHICLE SHUTS DOWN. DASH PANEL READS CHECK HYBRID SYSTEM CONDITIONS ARE EXACTLY THE SAME AS THE ZE3 WARRANTY ENHANCEMENT PROGRAM DESCRIBES. HOWEVER THE DTC CODE IS SLIGHTLY DIFFERENT SO DEALER AND TOYOTA WILL NOT FIX INVERTER. THE CAR IS DANGEROUS TO DRIVE AS THE SYMPTOMS APPEAR RANDOMLY, USUALLY AFTER AN ACCELERATION OF THE VEHICLE PUTS LOAD ON ENGINE. PLS HELP ME

ENGINE DEVELOPED AN OIL LEAK AROUND 120,000 MILES. DEALER RAN AN OIL LEAK TEST ($700)AND PERFORMED SOMETHING ELSE FOR $300 DOLLARS. NOTHING WORK. DEALER SAYS THE FIX IS TO BUY A NEW SHORT BLOCK FOR $6,700. I WILL NOT. I'M ADDING OIL MYSELF TO CAR ABOUT ONCE EVERY 10 DAYS

THE CAR STARTS AS NORMAL AND DRIVES NORMALLY BUT ONCE YOU START TO COME TO A STOP THE CAR SHUTS OFF AND WILL ONLY RESTART WHEN YOU DEPRESS THE GAS PEDAL BUT SHUTS DOWN AGAIN WHEN YOU RELEASE THE GAS PEDAL, NORMAL CITY STREETS AND HIGHWAY

A FEW MONTHS AGO I HAD THE REQUIRED SOFTWARE UPDATE TO ADJUST THE SAFETY FEATURE IN THE HYBRID SYSTEM IN CASE OF A FAILURE. WHILE DRIVING ON A SIDE STREET ON 3/1/19 I PRESSED THE GAS AFTER BEING STOPPED, THE CAR JERKED, AND THE CHECK HYBRID SYSTEM LIGHT CAME ON. THIS WAS ON RAILROAD TRACKS BUT THE CAR DID DRIVE ON THE GAS ENGINE A SHORT DISTANCE TO MAKE IT OVER THE RAILROAD TRACKS. I HAD THE CAR TOWED TO A TOYOTA DEALER WHO STATED THE INVERTER WAS BAD, BUT THAT TOYOTA WOULD REPLACE IT AS THEY EXTENDED THE WARRANTY. THIS SEEMS TO BE AN ISSUE THAT TOYOTA IS IGNORING. I ALSO OWN A 2014 TOYOTA PRIUS V WHICH IS ALSO PRONE TO THIS ISSUE. TOYOTA SHOULD ADDRESS THIS ISSUE BEYOND A MERE SOFTWARE UPDATE.

AT APPROXIMATELY 120,000 MILES WE STARTED RECEIVING MESSAGES FROM OUR DEALERSHIP THAT THE CAR WAS STARTING TO USE OIL EVEN THOUGH WE HAVE PERFORMED ALL REQUIRED MAINTENANCE AND ON TIME. THEN BETWEEN 130,000 AND 140,000 WE STARTING GETTING AN OIL LIGHT THAT WOULD COME ON DURING CORNERING. WE WERE TOLD TO KEEP A GALLON OF OIL WITH US AND FILL IT BETWEEN CHANGES AND WE DID. IT WOULD USE ABOUT 1 TO 2 QUARTS BETWEEN CHANGES. THEN AT 150,000 THE ENGINE BLEW UP. IT WAS WITHIN THE TIME LIMITS OF THE WARRANTY BUT NOT THE MILEAGE SO TOYOTA WOULD NOT HELP US OUT ON A NEW MOTOR. AFTER THAT I RESEARCHED ON LINE AND OTHERS ARE HAVING SIMILAR PROBLEMS. MOST IF NOT ALL OUR MILES WERE HIGHWAY CRUISING MILES SO EASY MILES. WE DROVE THIS THING LIKE A BABY. WE HAVE OWNED MANY OTHER VEHICLES TO WELL OVER 250,000 SO THIS IS NOT A CASE OF WE DON'T TAKE CARE OF OUR VEHICLES. THE MOTOR RIGHT BEFORE IT BLEW WAS MAKING A LOUD SCREECHING NOISE BUT NO LIGHTS ON THE DASH TO INDICATE THAT ANYTHING WAS WRONG. *TR

I'VE HAD MY PRIUS FROM 4-14 TO THE PRESENT 2016. I KEEP HAVING ISSUES WITH THE DEALERSHIP I TAKE IT TO FOR REPAIRS. [XXX] IN LA CRESCENTA CA. AFTER MENTIONING AND DESCRIBING ISSUES, THE STAFF THERE SAYS THAT UNLESS THE DASH LIGHTS UP WITH A MESSAGE AND GIVES A CODE, THEY CANT FIX IT. SO IN ORDER FOR THEM TO LOOK INTO IT ANY FURTHER THAN ME TELLING THEM DASH LIGHT IS NEC. I'VE TOLD THEM ABOUT THE AC NOISE FROM THE FIRST SAY I TOOK THE CAR IN TO GET SERVICES AT 33K. THEY SAY THEY DON'T HEAR OR SEE ANYTHING. MY AC COMPRESSOR SOUNDS LIKE ITS GOING TO EXPLODE WHEN AC IS ON. BRAKES HAVE BEEN EXTREMELY DIFF. TO EXPLAIN BECAUSE OF TERMINOLOGY. THEY SEEM TO LOSE THEIR POWER WHEN BEING PRESSED AND ABS SEEMS TO MALFUNCTION?? SO THEY DRIVE IT AND TELL ME ITS NOTHING I NEED TO WORRY ABOUT AND WILL BE FIXED WHEN CHANGED. CHANGE BRAKES AND THE PROB PERSISTS. NOT ONLY ABS BUT FIRESTONE SAYS MY HARDWARE HAS ISSUES AS WELL. I BRING IT TO THE ATTENTION OF THE STAFF AND NOTHING SEEMS TO GET DONE ABOUT IT... MY ODO. SPEEDOM IS/WAS OFF +2 MPH. MY WEATHER SEALS HAVE BEEN STRIPPED AND RIPPED OFF THE VEHICLE WHICH NOW CAUSES WATER LEAKS FROM EVERY CREVICE.. AND THE BIGGEST TWO OF ALL MY COMPLAINTS ARE 1- HYBRID BATT. FAN NEVER WORKED AND I WASN'T TOLD...HYB BATT HAS NEVER WORKED PROPERLY (DRAINS WAY TOO FAST WHEN STOPPED AT A LIGHT OR IN TRAFF) ALONG WITH THE HEAT CREATED BY THE BATT AND THE ENGINE THAT FILL UP THE CABIN AND WILL HAVE THE TEMP RAISED UPWARDS OF 90+ ON A 75 DEG DAY. 2- THE ECU'S IPM'S (OR SOMETHING LIKE THAT) HAS NOT BEEN CALIB. OR UPDATED. EVEN RECEIVED COVERAGE STICKERS FROM TOY HEADQUARTERS STATING FULL COVERAGE IF A.B.C.

"TAKATA RECALL" THIS IS OUR FIRST TOYOTA PURCHASE AND WE ARE EXTREMELY LET DOWN WITH THE FACT THAT IT IS LOSING AN EXCESSIVE AMOUNT OF OIL. THIS IS A SAFETY ISSUE. IN THE EVENT THAT THE ENGINE MAY CEASE IF IT RUNS OUT OF OIL. WE PREVIOUSLY HAVE ONLY HAD AMERICAN VEHICLES, AND WERE TOLD THAT TOYOTA IS A MUCH BETTER PRODUCT.. WELL AS OF THIS PAST APRIL, WE HAD THIS BRIEF LIGHT GO ON. IT DOESN'T STAY ON VERY LONG AND ONLY APPEARS WHEN YOU TURN A CURVE. THEN THE "OIL MAINTENANCE DUE" LIGHT APPEARED. THAT'S ODD, BECAUSE I JUST HAD MY OIL CHANGE DONE 2 MONTHS AGO! I WENT TO A LOCAL OIL SERVICE STATION IMMEDIATELY AND FOUND OUT I WAS DOWN TO ONLY ONE QUART OF OIL IN MY ENGINE. I'VE NEVER HAD THIS HAPPEN BEFORE! THEY LOOKED FOR A LEAK AND DIDN'T FIND ONE. THEY TOPPED OFF THE OIL AND I WAS FREE TO GO. WELL, THE SAME SCENARIO HAPPENED AGAIN IN JULY, ONLY 3 MONTHS AFTER THE LAST TOP OFF. I MADE AN APPOINTMENT WITH THE DEALER TO HAVE HIM LOOK IT OVER. THEY SAID IT NEEDED A SYSTEM ENGINE CLEANING, THERE WERE NO LEAKS, THEY GAVE IT AN OIL CHANGE, AND THE SPARK PLUGS LOOKED FINE.. $300 FOR THIS TO BE DONE. THEN THEY TOLD ME TO BRING IT BACK IN 1900 MILES... WELL THIS SEEMED TO WORK... UNTIL... NOW.. IN OCTOBER/NOVEMBER (2-3 MOS LATER) THE SAME ISSUE HAPPENED, AND NOW THEY ARE TELLING ME I NEED A NEW ENGINE THAT WILL COST ANYWHERE FROM $3000 TO $5800. I HAVE ONLY HAD THIS CAR GOING ON 5 YEARS. I HAVE NEVER HAD TO REPLACE AN ENGINE ON ANY CAR BEFORE.. WHERE IS THE TOYOTA QUALITY WE WERE TOLD TOYOTA STANDS BEHIND???

REQUEST HELP WITH 2011 TOYOTA PRIUS OIL CONSUMPTION, QUALITY, SAFETY, & AIR POLLUTION ISSUES: I BOUGHT THE CAR NEW. JUST AFTER 100,000 MILES I NOTICED IT WAS USING OIL BETWEEN OIL CHANGES. IT HAS GOTTEN WAY WORSE TO NOW AT 145,000 MILES IT USED 3 QTS IN 2000 MILES. IT DOES NOT WARN YOU THAT THE OIL LEVEL IS LOW UNTIL YOU ARE 3.5 QTS LOW & A MESSAGES SAYS YOU HAVE LOW OIL PRESSURE. THIS IS UNSAFE IN THAT THE CAR COULD GO DRY ON OIL AND THE ENGINE SIEZE UP. THERE IS A TSB ON THIS FOR OTHER TOYOTA VEHICLES, BUT NOT YET PRIUS. I BELIEVE PRIUS NEEDS TO BE ADDED TO THE LIST & I WANT TOYOTA TO REPLACE MY ENGINE OR AT LEAST THE PISTON RINGS. SO FAR TOYOTA IS NOT ADMITTING TO OIL CONSUMPTION PROBLEMS WITH THE PRIUS. THIS IS ALSO A POSSIBLE EMISSIONS ISSUE. I CONTACTED TOYOTA'S CUSTOMER EXPERIENCE CENTER IN FEB 2016 AND THEY SET-UP CASE NO. 1602170764 TO TRACK MY COMPLAINT. THEY REFERRED ME TO ALAMO TOYOTA IN SAN ANTONIO. I DO NOT BELIEVE THAT TOYOTA IS BEING PROACTIVE IN ADDRESSING THIS PROBLEM. AFTER RESEARCHING THIS ISSUE ON LINE, I HAVE FOUND MANY OTHER TOYOTA PRIUS OWNERS WITH THE SAME PROBLEM. THE PROBLEM DOES NOT SHOW UP UNTIL YOU ARE CLOSE TO THE 80,000-100,000 MILES POINT AND SO FOR THOSE FOLKS THAT DRIVE LESS, THE PROBLEM MAY NOT SHOW UP FOR ANOTHER COUPLE OF YEARS. I THANK YOU IN ADVANCE FOR ANY HELP THAT YOU CAN PROVIDE TO ME. I SPENT OVER $23,000 FOR THIS CAR AND HOPED IT WOULD GIVE ME TROUBLE-FREE TRANSPORTATION FOR MORE THAN 4 YEARS AND 100,000 MILES.

PRIUS STARTED CONSUMING OIL AROUND THE 105,000 MILE MARK. TWO MONTHS AGO, I TOOK IT TO THE DEALER AND THEY HAD ME COME BACK AFTER 1100 MILES AFTER MY OIL CHANGE. THEY SAID IT WAS CONSUMING OIL BECAUSE THE PISTON RINGS WERE LEAKING. THE LADY TRIED TO SELL ME A USED ENGINE FOR 3,000 OR 5,000 DOLLARS. I TOLD HER THAT IS WHY I BOUGHT TOYOTA BECAUSE I DIDN'T WANT TO SPEND MONEY AFTER 100,000 MILES. I HAVE LOOKED ONLINE AND THIS PRACTICALLY HAPPENING TO ALL THE 2010-2011 PRII. MY BUDDY OWNS AND CAMRY AND JUST HAD HIS BLOCK/PISTON RINGS CHANGED FOR THE SAME PROBLEM. THIS MORNING, I AM A 100 MILES FROM THE NEED OF AN OIL CHANGE, AND WHEN APPLY THE BREAKS I GET A YELLOW LIGHT COMING ON SAYING "NOT ENOUGH OIL PRESSURE". I GOOGLE THIS AND PEOPLE ARE SAYING IT IS BECAUSE MY OIL IS LOW AGAIN. I THINK TOYOTA IS TRYING TO AVOID HAVING TO RECALL THIS.

THIS CAR CONSUMES OIL... IT DOSE NOT LEAK THE OIL AND THE DEALER SAYS THAT ONE QUART IN 1200 MILES IS NORMAL... THIS OIL IS POLLUTING THE ATMOSPHERE AND IS EXPENSIVE. I FI WAS TOLD THAT IT WOULD CONSUME THIS MUCH OIL AT 100K, I WOULD NOT HAVE PURCHASED THE CAR.

ON START UP IN COLD WEATHER, <40*, AFTER SEVERAL DAYS OF NOT BEING USED, THE ENGINE RATTLES LIKE THERE'S A LOOSE ENGINE MOUNT. IT LASTS SEVERAL SECONDS, THEN STOPS. AFTER THE ENGINE WARMS UP IT'S FINE. THIS HAPPENED SEVERAL YEARS AGO AND I HAD TSB-0204-11 INSTALLED AT 38,000 MILES (12/18/13) AND HAD NO PROBLEM THE PROBLEM REOCCURRED YESTERDAY, 1/3/16, 76,000 MI, AND I'LL CHECK WITH MY MECHANIC FOR CODES.

EXCESSIVE OIL CONSUMPTION. RECENTLY I NOTICE OIL PRESSURE LOW LIGHT LIGHTS FREQUENTLY. IT USED THE OIL WAS CHANGED EVERY TIME THE MAINTENANCE LIGHT COME UP. ABOUT EVERY 5000 MILES. NOW THE LOW OIL PRESSURE COMES ALMOST EVERY 1000 MILES. THE CAR ONLY HAS 89K MILES.

THERE ARE 3 ISSUES I AM HAVING WITH THIS PRIUS. THE BRAKES ARE THE FIRST PROBLEM. AS OTHERS HAVE STATED, I TOO HAVE THE SAME LURCHING FORWARD WHEN BRAKING OVER BUMBY OR ROUGH ROADS. THIS HAS BEEN ONGOING OVER THE LAST FEW YEARS. SECOND, THE SUSPENSION IS CREAKING AND CRUNCHING WHEN MAKING TURNS AT LOW SPEEDS UNDER 20MPH. THIS HAPPENS WHEN THE WHEELS ARE TURNED ALL THE WAY RIGHT AND ALL THE WAY LEFT. THIS CRUNCHING NOISE HAPPENS WHEN BACKING OUT OF THE DRIVEWAY, MAKING U-TURNS, COMING TO A STOP ON AN INCLINE, AND BRAKING OVER SPEED BUMPS. I'VE HAD THE DEALER LOOK AT THIS FOR THE LAST YEAR WHEN I COME IN FOR SERVICE AND ONE TECH SAYS THEY CAN'T FIGURE IT OUT, ANOTHER TECH SAYS HE HEARS IT BUT CAN'T FIND THE ROOT OF THE PROBLEM, THE SERVICE MGR. ALSO WENT ON A DRIVE WITH ME AND REPRODUCES THE NOISE CONCERN BUT THE TECHS COULDN'T FIND IT. MOST WERE SUGGESTING NEW FRONT SUSPENSION COMPONENTS-STRUTS, TOWERS, LINKS, ETC. I REPLACED THE TWO FRONT STRUTS AND ALL OF THE EXTRA COMPONENTS-THE NOISE CONCERN IS STILL THERE. I AM VERY UPSET ABOUT THIS. THIRD ISSUE IS THE ICE-MOTOR. WHEN STOPPED AT A RED LIGHT AND THE ENGINE SHUTS OFF, THE CAR LURCHES FORWARD AND MAKES A CREAKING SOUND. IT'S APPEARS THAT SOMETHING IS NOT RIGHT. THE ENGINE SEEMS LIKE IT IS LOOSE. THE ENGINE ALSO MAKES RATTLING SOUND WHEN CRUISING LIGHTLY AT 15-25 MPH WITH THE ACCELERATOR PRESSED SLIGHTLY. THE SOUND IS COMING FROM THE PASSENGER SIDE, UNDER THE DASHBOARD-GLOVE COMPARTMENT AREA. THIS IS A RATTLE SOUND COMING FROM THE ENGINE. I'VE HAD THIS LOOKED AT AS WELL AND THE DEALER STATES THEY CANNOT DUPLICATE IT. I HAVE RECORDED ALL SOUNDS RELATED TO THESE CONCERNS AND AM TAKING IT BACK TO THE DEALER THIS MONTH.

IT SOUNDED LIKE A DIESEL ENGINE, MAKING A LOUD KNOCKING NOISE AND THE WHOLE CAR SHOOK. I TURNED THE CAR OFF AND THEN RESTARTED IT A COUPLE OF TIMES, BUT DID NOT EXPERIENCE THE ISSUE AGAIN. I DROVE BACK TO NC AND DID NOT EXPERIENCE THE ISSUE AT ALL. THE CAR WAS DUE FOR MAINTENANCE, SO B-4 TAKING IT IN, I RESEARCHED THE ISSUE ONLINE. I FOUND NUMEROUS PEOPLE THAT HAVE EXPERIENCED THE SAME PROBLEM ON THE "PRIUSCHAT.COM" WEB SITE, THERE WERE ALSO LINKS TO YOUTUBE VIDS THAT SHOWED THE SAME PROBLEM. I ALSO FOUND THAT THERE IS A TSB OUT FOR THIS ISSUE, BUT IT ONLY COVERS CERTAIN VINS AND THE DEALERS USUALLY REQUIRE THAT THEY CAN DUPLICATE THE PROBLEM B-4 THEY WILL PERFORM THE TSB. THE REPAIR IS TO REPLACE THE INTAKE MANIFOLD, BUT THIS DOES NOT APPEAR TO BE RESOLVING THE PROBLEM. THE PROBLEM APPEARS TO HAVE STARTED WITH THE 2010 MODEL WITH THE 1.8L MOTOR AND HAS YET TO BE RESOLVED. *TR

TL* THE CONTACT OWNS A 2011 TOYOTA PRIUS. THE CONTACT STATED THAT SHE NOTICED A LEAK COMING FROM INSIDE THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS WHERE THE CONTACT WAS ADVISED THAT THERE WERE SPIDERS IN THE HVAC DRAINAGE HOSE AND THE SPIDERS HAD CREATED A NEST EGG IN THE HOSE, WHICH CAUSED THE LEAK. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND THEY ADVISED HER THAT THE FAILURE WAS NOT COVERED UNDER HER WARRANTY. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE APPROXIMATELY 20,000. THE VIN WAS UNAVAILABLE.

STARTED CAR AFTER PROLONGED PERIOD OF COLD SOAK (PARKED FOR ONE WEEK OUTSIDE IN TEMPERATURES AROUND THE FREEZING MARK). ENGINE EXHIBITED A LOUD KNOCK/RATTLE AND HAD A DELAYED THROTTLE RESPONSE AS I WAS PULLING OUT ONTO THE STREET. HAD TO SHUT ENGINE DOWN (WITH VEHICLE LOCATED IN STREET, SAFETY CONCERN) TO STOP LOUD KNOCK AND RE-START ENGINE. RATTLE/KNOCK HAD DISAPPEARED. TOYOTA DEALERSHIP WHEN PRESENTED WITH ISSUE AND TOYOTA ISSUED TSB (T-SB 0012-10) ON THIS VERY ISSUE DECLINED TO PERFORM NECESSARY WORK SINCE THEY WERE NOT ABLE TO "RECREATE" THE ISSUE. I EXPLAINED THAT THIS ONLY HAPPENED ONCE AND TO REPLICATE THEY WOULD NEED TO PARK IT IN THE SAME CONDITIONS FOR A WEEK. I CANNOT LEAVE MY CAR WITH THEM FOR THIS LONG AND THEREFORE THIS IS AN UNREASONABLE REQUEST. MULTIPLE OWNERS HAVE EXPERIENCED THIS PROBLEM (AS A QUICK SEARCH ON YOUTUBE WILL CONFIRM) YET TOYOTA IS DENYING TO FIX THIS. *JS
