2011 Toyota Prius

TL* THE CONTACT OWNS A 2011 TOYOTA PRIUS. THE CONTACT STATED THAT THE PASSENGER'S SIDE HEAD LIGHT SUDDENLY FAILED AS THE DRIVER'S SIDE HEADLIGHT BECAME DIM. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE HEADLIGHT ASSEMBLY WOULD NEED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED AND NO SOLUTION WAS OFFERED. THE FAILURE MILEAGE WAS 86,000. UPDATED 04-29-14 *BF UPDATED 7/29/17*CN

WHEN I AM COMING TO STOP AT AN INTERSECTION ON A BUMPY OR UNEVEN OR SNOW COVERED ROAD AND APPLY THE BRAKES THE CAR LURCHES FORWARD INSTEAD OF STOPPING. I AM LUCKY I HAVEN'T HIT A CAR IN FRONT OF ME OR A PERSON CROSSING AT THE INTERSECTION. I HAVE BEEN READING THE OTHER COMPLAINTS AND THEY DESCRIBE EXACTLY WHAT IS HAPPENING WITH MY CAR. I HAVEN'T YET TRIED TO GET THIS FIXED, BUT I AM STARTING TODAY. *TR

TL* THE CONTACT OWNS A 2011 TOYOTA PRIUS. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 20 MPH ON UNEVEN ROAD SURFACES, THE VEHICLE BEGAN TO VIBRATE IN A BOUNCING MOTION, WHEN THE BRAKE PEDAL WAS DEPRESSED. THE FAILURE RECURRED FOUR TIMES. THE VEHICLE HAD NOT BEEN DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 25,000.

THE BRAKES TOTAL DISENGAGE WHEN APPLIED ON BUMPY ROADS THEN WORK AGAIN AFTER GETTING TO A SMOOTH SURFACE. I REPORTED THIS TO THE SERVICE MANAGER AT THE NEW CAR OWNER MEETING AT TOYOTA AND WAS TOLD THAT I JUST HAVE TO GET USE TO ANTILOCK BRAKES. I HAVEN'T GOTTEN INTO AN ACCIDENT YET BUT I HAD SEVERAL CLOSE CALLS ALMOST HITTING CARS IN FRONT OF ME ON BUMPY ROADS. HAS THERE BEEN A RECALL FOR THIS PROBLEM? *TR

MY CAR HESITATES TO STOP OR SLOW DOWN WHEN BRAKES ARE APPLIED DRIVING OVER A POTHOLE, SLICK SURFACE, METAL ROAD COVER OR A MANHOLE. INSTEAD OF SLOWING/STOPPING, THE CAR SEEMS TO EJECT FORWARD. I TOOK IT TO THE DEALERSHIP WHERE I BOUGHT MY CAR AND DROVE WITH A SERVICE TECH AND HE SAID IN OVER 20 YEARS OF HIS EXPERIENCE, HE'S NEVER SEEN THIS. I TRIED TO EXPLAIN THAT THIS CAR (AND TECHNOLOGY WITH REGENERATIVE BRAKING) IS ONLY 3 YEARS OLD, BUT HE DIDN'T SEEM TO BUY MY COMPLAINT, NOR WERE WE ABLE TO REPRODUCE THIS ISSUE WHEN I DROVE WITH A TECHNICIAN AROUND THE BLOCK. THERE ARE SEVERAL ONLINE DISCUSSIONS REGARDING THIS PARTICULAR ISSUE : HTTP://MONEY.CNN.COM/2010/02/04/AUTOS/PRIUS_TIMELINE/?WPMP_SWITCHER=MOBILE HTTP://WWW.EETIMES.COM/AUTHOR.ASP?SECTION_ID=30&DOC_ID=1284377. *TR

RE: NHTSA 14V053000/HYBRID PROPULSION SYSTEM...I DID NOT RECEIVE A RECALL NOTICE IN THE MAIL. MY DAUGHTER OWNS A NEW PRIUS AND SHE DID NOT RECEIVE ANY NOTICE EITHER. MY CAR ENGINE DID NOT SHUT OFF BUT MY DAUGHTER'S ENGINE HAS SHUT OFF. YOU SHOULD ASK TOYOTA TO SHOW PROOF OF ITS RECALL MAILINGS. I'LL BET THE FARM THAT THEY CAN'T. *TR

SINCE THE FIRST SET OF BULBS HAVE WENT OUT IN THE VEHICLE AT AROUND 48,000 MILES I WILL NOW BE INSTALLING THE 4TH SET OF BULBS... ORIGINAL + 3. THE BULBS IN THE PRIUS FAIL WITHIN 24 HOURS OF EACHOTHER EACH TIME AND IT IS GOING THREW HEADLIGHTS AROUND EVERY 10,000 MILES AT THIS TIME. THIS IS COMPLETELY UNACCEPTABLE AND DANGEROUS FOR A COMMUTER VEHICLE. *TR

ON TWO SEPARATE OCCASIONS IN DECEMBER OF 2013, WITH TWO DIFFERENT DRIVERS, THE BRAKES ON OUR 2011 MODEL YEAR PRIUS (PURCHASED NEW IN FEBRUARY 2012), FAILED TO ENGAGE. THE FIRST TIME OCCURRED WHEN I WAS DRIVING (WITH ONE OF MY TEENAGERS IN THE CAR WITH ME), AND THE SECOND TIME OCCURRED WHEN MY WIFE WAS DRIVING THE CAR ALONE. IN BOTH INSTANCE WE PRESSED THE BRAKE PEDAL, BUT THE BRAKES FAILED TO RESPOND AT ALL. ALTHOUGH IT IS WINTER, THE ROADS WERE CLEAR, AND THE CAR DID NOT SLOW DOWN AT ALL WHEN THE BRAKES WERE PRESSED / APPLIED. INTERESTINGLY, AFTER 30 - 60 SECONDS, THE BRAKE FUNCTION RESTORED ITSELF. SINCE DECEMBER THE CAR HAS BEEN AT THE SHOP AT THE TOYOTA DEALERSHIP WHERE WE PURCHASED THE CAR. THE SHOP HAS BEEN UNABLE TO IDENTIFY THE SOURCE OF THE PROBLEM. ADDITIONALLY, THE SHOP INDICATED THEY CONTACTED TOYOTA MECHANICS AND SERVICE SUPPORT STAFF TO HELP IDENTIFY AND FIX THE PROBLEM, BUT TOYOTA CLAIMED THEY NEVER HEARD OF SUCH A PROBLEM OR ANYTHING LIKE IT. MOREOVER, TOYOTA REFUSES TO MAKE ANY REPAIRS OR CHANGE ANY PARTS (EVEN THOUGH THE CAR IS STILL UNDER WARRANTY). YET, THIS PAST WEDNESDAY (FEBRUARY 12, 2014), TOYOTA ANNOUNCED A RECALL ON RAV4'S AND OTHER MODELS FOR A SOFTWARE PROBLEM THAT CAUSES THE ANTI-BRAKES TO INTERMITTENTLY TURN OFF. THIS IS PARTICULARLY TROUBLING, GIVEN TOYOTA'S CLAIM THAT THEY NEVER HEARD OF ANYTHING LIKE THIS AND DID NOT KNOW WHAT TO FIX. FURTHER, TOYOTA ANNOUNCED A RECALL ON THE PRIUS ITSELF, FOR A SOFTWARE PROBLEM THAT MIGHT CAUSE THE CAR TO TURN OFF COMPLETELY WHILE DRIVING. CLEARLY, TOYOTA HAS A PROBLEM WITH ITS SOFTWARE IN A NUMBER OF VEHICLES. AT THIS POINT, ALL I HAVE RECEIVED IS CORPORATE DOUBLE TALK, AND I URGE THE NHTSA TO PURSUE THIS MATTER AS VIGOROUSLY AS POSSIBLE. *TR

ON JAN. 18TH, 2014 I WAS LEAVING FL TO RETURN TO NC, WHEN I STARTED UP MY PRIUS AND WAITED FOR THE GAS ENGINE TO START, IT DID NOT WANT TO START. 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

I PURCHASED A SET OF 4 MICHELIN DEFENDER XT TIRES FOR MY 2011 PRIUS II FROM COSTCO ON 11/29/2013. THE TIRES ARE MARKETED BY MICHELIN AS LLR (LOW ROLLING RESISTANCE) TIRES. HOWEVER UPON INSTALLING THEM AND OPERATING THE VEHICLE FOR NEARLY 1000 MILES, I FOUND THE MPG TO BE NEARLY 10 MPG. LESS THAN THE OEM TIRES THAT THESE REPLACED. THE ROLLING RESISTANCE OF THESE TIRES ARE HIGH. VEHICLE ALMOST FEELS LIKE BEING DRIVEN OVER SAND. AS SOON AS I TAKE MY FOOT OFF THE ACCELERATOR, THE VEHICLE DECELERATES RAPIDLY, MUCH FASTER THAN THE OEM TIRES. I CHECKED THE TIRE PRESSURE, ALIGNMENT, AND WHEEL BEARINGS, ALL ARE WITHIN SPECS. IT APPEARS TO ME THAT THE HYSTERESIS LOSSES IN THIS TIRE MATERIAL ARE FAIRLY HIGH. THIS TIRE SHOULD NOT BE SOLD AS A LOW ROLLING RESISTANCE TIRE. IT IS BEING FALSELY ADVERTISED AS HAVING THIS CAPABILITY TO INCREASE SALES. THE MPG DIFFERENCE WAS MEASURED BY CALCULATING THE TRUE MILES FROM MY GPS UNIT AND DIVIDING THE RESULT BY THE GALLONS TO FULL AT THE SAME PUMP. THIS WAS DONE THREE TIMES TO ACCURATELY ACCESS THE TRUE MPG DIFFERENCE. NO OTHER FACTORS ON THE VEHICLE HAS BEEN CHANGED. ONLY CHANGE HAS BEEN REPLACEMENT OF THE TIRES. *TR
