HEAD LIGHT ARE INTERMITTENT; SAME PROBLEM AS 2006 AND LATER RECALL

THE HEADLIGHTS ON MY 2005 PRIUS CONTINUE TO GO OUT. WE REPLACE THE BULBS BUT EVEN WITH BRAND NEW BULBS WILL BE DRIVING AND AFTER ABOUT 60 SECONDS OF HEADLIGHTS BEING ON THE LIGHT WILL TURN OFF. SOMETIMES ONLY ONE TURNS OFF BUT OFTEN BOLT TURN OFF AND WE'RE IN COMPLETE DARKNESS DRIVING ON THE ROAD. WE HAVE TO TOGGLE THE HEADLIGHT CONTROL OFF AND ON SEVERAL TIMES BEFORE THEY TURN ON AGAIN, WHICH LEAVES US DRIVING IN COMPLETE DARKNESS AND IT'S A BIG SAFETY HAZARD! AGAIN, BRAND NEW BULBS HAVE THIS ISSUE, TOO. GETTING THE WHOLE HEADLIGHT AND COMPUTER BEHIND IT REPLACED IS VERY EXPENSIVE. THIS IS A BIG SAFETY ISSUE AND IT HAS BEEN HAPPENING AND GETTING WORSE FOR OVER A YEAR.

Mileage: 164,000

THE PASSENGER SIDE FRONT HEADLIGHT STARTED GOING OFF AUTOMATICALLY AFTER A WHILE OF TURNING ON. IF I TURN IT OFF AND ON AGAIN, IT LIGHTS UP AND THEN FIRST DIMS AND THEN TURNS OFF ON ITS OWN. THE LIGHTS HAVE BEEN REPLACED AND IT DID NOT SOLVE THE PROBLEM. THIS IS VERY DANGEROUS FOR NIGHT TIME DRIVING AS THE DRIVERS WILL NEVER KNOW WHEN THE HEADLIGHTS WILL GO OUT. THIS IS NOT A RANDOM INCIDENT; IT IS ONE OF THE MOST COMMON PROBLEMS OF GEN 2 PRIUS (04-09) THAT I FOUND ONLINE. I AM ATTACHING A DOCUMENT THAT LISTS SOME ONLINE FORUMS WHERE OTHER PRIUS OWNERS HAVE REPORTED SIMILAR PROBLEMS. TOYOTA SETTLED A LAWSUIT FOR 06-09 PRIUS, YET THERE IS NO RECALL FOR THE HEADLIGHT ISSUE OF GEN 2 PRIUS.

Mileage: 10

WHILE DRIVING DRIVER SIDE HEADLIGHT WILL GO OUT, FOLLOWED BY PASSENGER HEADLIGHT. BOTH WILL RETURN ON WHEN THE HEADLIGHTS ARE TURNED OFF THEN ON AGAIN, ONLY TO OCCUR AGAIN WITHIN 10 MINUTES. BOTH HEADLIGHTS HAVE BEEN REPLACED WITHIN THE LAST 10 DAYS.

Mileage: 210,000

HEADLAMPS RANDOMLY TURN OFF WHILE DRIVING, BUT USUALLY ONLY ONE AT A TIME. LAST NIGHT (12/18/18), BOTH LIGHTS WENT OUT AT THE SAME TIME AND I WAS UNABLE TO SEE THE ROAD AS IT WAS POORLY LIT. WHEN LAMPS DO TURN OFF WHILE DRIVING, TURNING THEM OFF AND ON A FEW TIMES WILL USUALLY GET THE IT TO COME BACK ON. THIS IS DEFINITELY A HAZARD AND A RECALL IS ABSOLUTELY REQUIRED.

Mileage: 204,000

COMBINATION METER INTERMITTENTLY NOT FUNCTIONING. WHEN TURNING THE CAR ON, SOMETIMES THE DASH METER WORKS, SOMETIMES IT'S JUST BLACK AND CONTINUES THE ENTIRE TIME THE CAR IS RUNNING. THEN WHEN TRYING TO TURN THE CAR OFF, IT WILL NOT TURN OFF, WHICH IS A MAJOR SAFETY CONCERN. WHEN THIS OCCURS, THERE ARE NO DASH LIGHTS AT ALL TO INDICATE FUEL AMOUNT, ODOMETER READING, DOOR OPEN SIGNAL, CHECK ENGINE, MAINTENANCE REQUIRED AND SO ON. THE SPEED BEING DRIVEN IS NOT SHOWING EITHER WHICH IS ANOTHER MAJOR SAFETY ISSUE. CRUISE CONTROL ALSO DOES NOT FUNCTION, THE CENTER TOUCHSCREEN DOES NOT DISPLAY HYBRID MOTOR INFORMATION OR MPG. THE BEEPING WHEN BACKING UP DOES NOT FUNCTION. ALSO THE REAR HATCH WILL NOT OPEN WHILE CAR IS RUNNING WHICH IS ALSO A MAJOR SAFETY ISSUE IN ADDITION TO ALL OF THE OTHER FUNCTIONS NOT AVAILABLE. THE ODOMETER IS NOT RECORDING MILEAGE DURING THESE TIMES WHICH MAKES IT DIFFICULT TO DO PROPER MAINTENANCE THAT GOES BY MILEAGE, SUCH AS OIL CHANGES.

Mileage: 225,000

HEADLIGHT FAILURE.....WHILE DRIVING. I START OUT WITH MY LIGHTS ON, AND RANDOMLY DRIVING DOWN THE ROAD ONE HEADLIGHT, OR THE OTHER, WILL GO OUT, OR BOTH WILL GO OUT. I REPLACED THE BULBS, HAVE HAD MECHANICS GO OVER THE CAR......BEFORE I JOINED A PRIUS CHAT AND LEARNED THIS IS A "KNOWN ISSUE".....BUT STILL NO RECALL? I'VE BEEN PULLED OVER BY VARIOUS LAW ENFORCEMENT 4 TIMES IN THE LAST 4 MONTHS! ..........BELOW IT ASKS FOR A DATE ON THE INCIDENT...IT HAPPENS FREQUENTLY. IT'S BEEN HAPPENING FOR AT LEAST A YEAR.

Mileage: 215,000

HEADLIGHTS GO OUT WHILE DRIVING, IT TAKES TURNING THEM ON AND OFF A FEW TIMES TO TURN THEM BACK ON. IT IS RANDOM, SOMETIMES PASSENGER SIDE, SOMETIMES DRIVERS SIDE, SOMETIMES BOTH. TOYOTA SETTLED A CLASS ACTION LAWSUIT WITH 2006 - 2009 PRIUS, MINE IS 2005, BUT THIS IS A SAFETY ISSUE AND IS EXTREMELY DANGEROUS. WHEN BOTH HEADLIGHTS GO OUT, IT MAY TAKE SEVERAL TRIES TO GET THEM TO COME BACK ON, LEAVING ME WITHOUT HEADLIGHTS AS I'M DRIVING MY KIDS TO SCHOOL EARLY IN THE MORNING IN THE DARK, GOING 65MPH DOWN THE HIGHWAY. CURRENTLY SAVING TO GET FIXED(CAR WAS A GIFT). I CALLED TOYOTA FOR AN ESTIMATE ON THIS KNOWN PROBLEM AND THEY SAID THEY I WOULD HAVE TO BRING IT IN AND THEY WOULD CHARGE ME $85 FOR THEM TO DIAGNOSIS THE PROBLEM. TOYOTA IS NOT TAKING ANY RESPONSIBILITY FOR THIS PROBLEM, WHICH CLEARLY THEY ARE AWARE OF AND SOMEHOW SKIRTED OUT OF A RECALL OR ANY LIABILITY FOR ALL MODELS.

Mileage: 170,121

HEADLIGHTS COME ON INTERMITTENTLY. USUALLY THEY WORK FINE, BUT EVERY SO OFTEN SINCE MY FRIEND FIRST TOLD ME MY LIGHTS WERE OUT LAST WEEK, THEY DON'T TURN ON WHETHER THE CAR IS RUNNING OR NOT. IT CAN HAPPEN TO ONE OR BOTH LIGHTS AT A TIME, AND IS UNPREDICTABLE, MAKING ME AFRAID TO DRIVE AT NIGHT. I TOOK IT TO THE MECHANIC'S TODAY, BUT THE LIGHTS WERE WORKING AND HE COULDN'T DETERMINE THE PROBLEM. THE BULBS ARE FINE, AS LONG AS THEY ARE ABLE TO TURN ON, AND THE MECHANIC AGREED THE BULBS DO NOT NEED REPLACEMENT.

Mileage: 150,000

THE HID HEADLIGHTS WORK UPON START UP THEN SHUT OFF AFTER ABOUT 10 SECONDS. REPLACING THE BULB DOES NOT FIX IT. THIS IS A SAFETY ISSUE AS THE HEADLIGHTS DONT STAY LIT DURING NIGHTTIME HOURS.

Mileage: 205,000

THE HEADLIGHT WILL GO OUT, AND IT WILL COME ON AGAIN IF YOU TURN THE HEADLIGHTS OFF AND TURN THEM BACK ON AGAIN. THIS WILL HAPPEN MULTIPLE TIMES IN AN EVENING, AND IT HAPPENS EVERY TIME THE CAR IS DRIVEN.

DRIVER SIDE HEADLIGHT KEEPS GOING OUT AND I HAVE TO TURN OFF HEADLIGHTS AND TURN THEM BACK ON TO MAKE THEM WORK. THIS IS NOT SAFE AT ALL. IT HAPPENS STANDING STILL AND DRIVING.

Mileage: 101,000

HEADLIGHT GOES OUT REPEATEDLY. HEADLIGHT WORKS AGAIN AFTER HEADLIGHTS ARE TURNED OFF THEN ON AGAIN. STARTED WITH THE SAME ONE HEADLIGHT GOING OUT. NOW THE OTHER. SOMETIMES BOTH GO OUT, INCLUDING AT NIGHT. EACH TIME THE HEADLIGHTS MUST BE TURNED OFF THEN ON AGAIN AND THEY WORK FOR A WHILE LONGER. LIGHTS GO OUT WHEN STATIONARY AND WHEN DRIVING.

Mileage: 274,000

THE HEADLIGHTS ARE PRONE TO TURNING TO OFF RANDOMLY, SOMETIMES ONE SIDE, OTHER TIMES BOTH SIDES. AFTER TURNING THEM ON/OFF AT THE STEERING COLUMN THEY WILL COME BACK ON FOR A WHILE THEN THE ISSUE STARTS OVER. THIS PROBLEM OCCURS WITH THE VEHICLE EITHER MOVING OR IN THE STATIONARY MODE. NO HEADLIGHTS WHEN DRIVING AT NIGHT IS A DEFINITE SAFETY HAZARD. SO FAR, TOYOTA REFUSES TO HONOR A FIX!

Mileage: 226,000

HEADLIGHT CAME OFF AND ON WHILE I'M DRIVING ALL FUSE OK ALL BULBS OK LOOKING ON THE WEB APPEARS LIKE THIS IS A COMMON PROBLEM ON THIS VEHICLE ALSO RADIO LIGHT SAME PROBLEM

TL* THE CONTACT OWNS A 2005 TOYOTA PRIUS. WHILE DRIVING 25 MPH AT NIGHT, THE HEADLIGHTS FAILED TO WORK WITHOUT WARNING. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS CONTACTED AT 800-331-4331 AND STATED THAT THE VIN WAS NOT INCLUDED IN A RECALL. THE APPROXIMATE FAILURE MILEAGE WAS 181,308.

Mileage: 181,308

THE HEADLIGHTS ARE CONTINUALLY REPLACED (ONCE EVERY 6 MONTHS FOR THE LAST YEAR AND A HALF OR MORE), AND REPLACEMENTS OF AUTHORIZED PARTS KEEP FAILING, CONSISTENT WITH ISSUES PRESENTED IN THIS FORUM: HTTPS://PRIUSCHAT.COM/THREADS/HEADLIGHT-PROBLEM.34584/. I HAVE CHECKED AND RECHECKED WITH DEALERSHIP BUT THEY ONLY OFFER $500+ REPLACEMENT AND NO RECALLS OR FIXES FOR THE GENERAL ISSUE.

PASSENGER HEADLIGHT GOES OFF INTERMITTENTLY. TURN SWITCH OFF AND ON AND COMES ON AGAIN. HAVE HAD BULB REPLACED X2 AND NOW TOYOTA DEALER SAYS THAT TOYOTA HAS A BULLETIN ABOUT IT. NOTE TO THE TUNE OF $500 TO FIX. IN RESEARCHING THIS SEEMS TO BE A COMMON PROBLEM. IT'S A HAZARD AT NIGHT OR IN RAIN OR INCLEMENT WEATHER AND EVIDENTLY SOMETHING TOYOTA HAS HAD COMPLAINTS ABOUT ENOUGH TO PUT OUT A BULLETIN. VEHICLE IN MOTION, HIGHWAY MILES. I BELIEVE SOME SORT OF SHORT BUT CERTAINLY NOT MECHANIC. THIS HAS BEEN HAPPENING SINCE JANUARY 2017. TWO NEW BULBS PLUS LABOR AND NOW TOLD WIRING MECHANISM. HELP. IF TOYOTA KNOWS A PROBLEM, ADDRESS IT IN A RECALL.

HEAD LIGHTS DIMS AFTER 2 MINUTES OF DRIVING THEN FEW SECONDS LATER COMPLETELY SHOTS OFF.

Mileage: 70,000

THE PASSENGER SIDE HEADLIGHT HAS GONE OUT 3 TIMES IN A 3 YEAR PERIOD. EACH TIME THE BULB HAS BEEN REPLACED AT SIGNIFICANT EXPENSE ($300 AT THE DEALERSHIP), BUT HAS GONE OUT AGAIN AFTER A PERIOD OF SEVERAL MONTHS. THE LAST TIME IT HAPPENED WAS 11/2014. SINCE THEN WE HAVE BEEN UNABLE TO USE THE CAR AT NIGHT DUE TO THE OBVIOUS SAFETY ISSUE IT PRESENTS. WE CANNOT AND WILL NOT CONTINUE TO SPEND HUNDREDS OF DOLLARS TO REPLACE THESE BULBS WHEN THERE IS CLEARLY A DEFECT IN THE SYSTEM. BASED ON THE HUNDREDS OF SIMILAR REPORTS I HAVE SEEN ONLINE ABOUT THIS VERY ISSUE, I KNOW MY STORY IS NOT UNIQUE. I REQUEST THAT A RECALL BE ISSUED FOR THE AFFECTED MODEL YEARS, WHICH INCLUDES 2005!

Mileage: 87,401

MY DRIVER'S SIDE HEADLIGHT DOESN'T STAY ON. IT WILL GO ON FOR A MINUTE THEN TURN OFF. IF I TURN THE HEADLIGHTS OFF AND ON, IT STARTS BACK UP AGAIN, THEN GOES OUT AGAIN. I REPLACED THE HEADLIGHT CONTROL AND IT STILL CONTINUES. IT DOES THIS IF I'M DRIVING OR NOT. *TR

MY HEADLIGHT INTERMITTENTLY GOES OFF WHILE DRIVING & THEN BACK ON. I PAID A LOCAL MECHANIC TO CHECK IT OUT; HE COULDN'T FIND ANY LOOSE CONNECTIONS, ETC. BUT DID ADVISE ME OF A CLASS ACTION SUIT FOR THIS EXACT PROBLEM ON THE 06 - 09 MODEL YRS. I'VE CONTACTED BOTH A LOCAL DEALERSHIP & TOYOTA CORP. WHO BOTH REFUSE TO FIX IT AT NO COST TO ME (SEE ATTACHED RESPONSE FROM TOYOTA CORP. *TR

LEFT HEADLIGHT IS DIM, GOES OUT, COMES BACK ON WHEN LIGHTS ARE TURNED OFF AND THEN ON AGAIN, BUT THEN DIMS AND EVENTUALLY FAILS AGAIN. THIS HAPPENS WHETHER IN MOTION OR STOPPED, REGARDLESS OF SPEED, AND WHETHER TURNING OR GOING STRAIGHT. I READ THAT THIS IS VERY COMMON AMONG 2005-2009 PRIUSES, AND A DESIGN CHANGE IN 2010 FIXED IT. THAT MEANS IT IS CAUSED BY A DESIGN PROBLEM, AND TOYOTA SHOULD DO A RECALL TO FIX IT.

Mileage: 79,650

THE HEADLIGHTS ARE GOING ON AND OFF WHILE DRIVING. THEY WILL STAY ON FOR A FEW MINUTES AND THEN THE LEFT OR RIGHT ONE WILL GO OUT SO THEN I'LL RESET THE LIGHTING AND IT WILL COME BACK ON AND THEN I WILL GO OUT AGAIN. SOMETIMES THE RIGHT SOMETIMES IT'S THE LEFT SOMETIMES IT'S BOTH.

ONE HEADLIGHT OR BOTH WILL RANDOMLY GO OUT WHILE DRIVING. HAS HAPPENED SPORADICALLY 6 OR SO TIMES OVER THE LAST 6 MONTHS, INCLUDING THIS EVENING WHEN BOTH HEADLIGHTS FAILED. TOTALLY RANDOM, CAN HAPPEN ON SHORT OR LONG TRIPS, CITY STREETS OR HIGHWAY. SO FAR LIGHTS HAVE COME BACK ON BY CYCLING THE LIGHT SWITCH ON AND OFF

TL* THE CONTACT OWNS A 2005 TOYOTA PRIUS. WHILE THE VEHICLE WAS STATIONARY, THE BRAKE LIGHTS MALFUNCTIONED. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE. THE FAILURE MILEAGE WAS 130,000.

Mileage: 130,000

BOTH HEADLIGHTS WILL FLICKER AND GO OUT, MOSTLY AT DIFFERENT TIMES THAN THE OTHER BUT CAN HAPPEN AT THE SAME TIME. BY TURNING THE HEADLIGHT SWITCH OFF, THEN BACK ON AFTER 10 TO 15 SECONDS THEY WILL COME BACK ON. DRIVING ON THE FREEWAY THIS LEAVES YOU IN A VERY DANGEROUS SITUATION. THANK GOD FOR FOG LIGHTS, A LIFE SAVER AT 70 MILES AN HOUR. THIS CAN ALSO HAPPEN SITTING IN MY DRIVEWAY BEFORE LEAVING FOR WORK.

Mileage: 260,000

ONE OF MY FRONT HEADLIGHT ALWAYS GOES OUT ONCE I MAKE A TURN BY USING A TURN SIGNAL. IF I SWITCH THE HEADLIGHT OFF AND ON AGAIN, THE HEAD LIGHT WILL COME BACK. I READ SIMILAR POST FROM WEBSITE, AND FOUND SOME PEOPLE HAVE THE SAME PROBLEM WITH ME. WE ALL SUSPECT THIS IS A DESIGN PROBLEM BY THE MANUFACTURER.

Mileage: 150,000

HEAD LIGHTS TURN OFF AFTER BEING ON FOR A WHILE. TURNING OFF HEADLIGHT SWITCH AND TURNING IT BACK ON TURNS THE LIGHT BACK ON. HIGH BEAM STITCH DOES NOT AFFECT THE LIGHT WHICH IS OFF. THIS HAPPENS WHILE IN MOTION ON BOTH HIGHWAYS AND CITY STREETS. THIS OCCURS FREQUENTLY

Mileage: 175,000

HEADLIGHTS GO OFF, ONE AT A TIME, INTERMITTENTLY, WHILE DRIVING ON ANY ROAD. IF I TURN THE LIGHTS ALL THE WAY OFF AND THEN BACK ON AGAIN THEY WILL USUALLY STAY ON FOR 15 MINUTES BEFORE GOING OFF AGAIN. I AM NOT AWARE THAT THEY HAVE BOTH GONE OFF AT ONCE, BUT I HAVE NOT DRIVEN THE CAR AT NIGHT YET

I WAS DRIVING THROUGH NEVADA AT 11 PM AT NIGHT TOWARDS RENO (APPROX. 180 MILES AWAY) ON I-80 AT 75 MPH WHEN SUDDENLY MY HEADLIGHTS WENT OUT. I IMMEDIATELY TRIED TURNING THE LIGHTS OFF AND ON MANUALLY WITH MY LEFT HAND, AND THE LIGHTS CAME ON AGAIN (I COULDN'T SEE ANYTHING IN THE DARK, SCARED OUT OF MY MIND). THEN, ABOUT 2 MINUTES LATER THE SAME THING HAPPENED (I WAS DRIVING SLOWER THIS TIME). I DID THE SAME TURNING OFF AND ON AGAIN, AND THE LIGHTS CAME BACK ON AGAIN, ALTHOUGH SOMEWHAT DIMMER. A FEW MINUTES LATER (5 MINUTES?) I WAS PASSED BY A VEHICLE, THAT THEN SLOWED DOWN AND CAME IN BEHIND ME, AND THEN TURNED ON THE POLICE LIGHTS AND I IMMEDIATELY PULLED IN AN EXIT RAMP (FORTUNATELY THERE WAS ONE RIGHT THERE). AFTER THE POLICEMAN CHECKED MY LICENSE AND REGISTRATION, HE INFORMED ME THAT ONE OF MY HEADLIGHTS WAS OUT. HE ASKED ME TO TRY AND FLICK ON AND OFF THE LIGHTS A COUPLE OF TIMES, AND TO TRY THE BRIGHTS, BUT NONE OF THIS BROUGHT IT BACK INTO WORKING ORDER. HE THEN OUT OF THE BLUE MENTIONED TO ME (WITHOUT ME BRINGING THIS UP) THAT THE PRIUS' WERE NOTORIOUS FOR HAVING INTERMITTENT ISSUES WITH THE HEADLIGHTS, ESPECIALLY ON THE PASSENGER SIDE OF THE CAR (WHICH IS THE SIDE THAT WAS OUT, COINCIDENTLY). HE LET ME PROCEED USING ONE HEADLIGHT WITHOUT TICKETING ME. A FEW MILES LATER I PULLED INTO A REST AREA AND TURNED OFF THE CAR FOR A FEW MINUTES WHILE I WENT TO THE BATHROOM, AND WHEN I GOT BACK INTO THE CAR AND TURNED ON THE HEADLIGHTS THEY BOTH CAME ON, BUT WITHIN 20 SECONDS THE PASSENGER SIDE LIGHT WENT OUT AGAIN. WHEN I GOT HOME THE NEXT DAY AND TURNED ON THE HEADLIGHTS THEY WERE BOTH WORKING AGAIN. THIS INTERMITTENT FAILURE OF THE PASSENGER SIDE HEADLIGHT HAS OCCURRED A FEW TIMES IN THE PAST, AND I HAVE HAD THE TOYOTO DEALER LOOK INTO IT AND THEY CLAIMED THAT IT WAS FIXED. HOWEVER, THIS TIME IT WAS LIFE THREATENING.

Mileage: 112,000

LEFT AND RIGHT HEADLIGHTS SPORADICALLY TURN OFF WHICH IS EXTREMELY HAZARDOUS WHEN DRIVING AT NIGHT IN ROADS WITHOUT STREET LIGHTS. DEFINITELY A SAFETY ISSUE WHICH TOYOTA MUST ISSUE A RECALL. LIGHT BULBS ARE NOT THE ISSUE. THE ISSUE IS IN THE COMPUTER OR BALAST THAT CONTROLS THE LIGHTS.

Mileage: 197,479

HEADLIGHTS WILL RANDOMLY GO OUT WHILE DRIVING. MOST OF THE TIME IT IS ONLY ONE HEADLIGHT BUT SOMETIMES BOTH GO OUT. TO "RE-LIGHT" THEM YOU HAVE TO TURN THE HEADLIGHTS OFF AND THEN BACK ON. REPLACING THE BULBS DOES NOT SOLVE THE PROBLEM. AT NIGHT THIS HAS ALMOST LED TO DISASTROUS EFFECTS AND, FROM A RISK MANAGEMENT PERSPECTIVE, IT IS ONLY A MATTER OF TIME BEFORE SOMETHING BAD DOES HAPPEN AS A RESULT OF LOSING YOUR EXTERNAL HEADLIGHTS WHILE DRIVING AT NIGHT. IT HAPPENS WHETHER THE CAR IS STATIONARY OR IN MOTION. SOME ELEMENT OF THIS HAPPENS EVERY TIME I DRIVE THE CAR (MULTIPLE TIMES PER DAY).

Mileage: 206,000

WHILE DRIVIN BOTH HEADLIGHT TURN OF INTERMITTENTLY WHILE I CAN TURN OFF AND BACK ON THEY COME ON TO ONE OR THE OTHER OR BOTH GOING BACK OFF SOMETIMES AND SOMETIMES THEY WORK PERFECTLY THIS IS VERY DANGEROUS AS YOU ONLY USE HEADLIGHTS AT NIGHT.

DRIVER'S SIDE HEADLIGHT WENT OUT IN 2015 AND WAS REPLACED BY LOCAL MECHANIC. BEFORE IT WENT OUT IT HAD FLICKERED BUT CAME BACK ON. I WAS DRIVING AT NIGHT WHEN IT WENT OUT AND WAS PULLED OVER BY POLICE. FORTUNATELY I ONLY GOT A WARNING. MARCH 2016 THE HEADLIGHT WENT OUT AGAIN (I NOTICED IT IN MY DRIVEWAY) AND WAS REPLACED AT A TOYOTA DEALERSHIP ON 21 MARCH 2016. THAT VERY DAY, THE HEADLIGHT WENT OUT AGAIN (NOTICED IT IN MY DRIVEWAY). IT WOULD COME ON PERIODICALLY BUT KEPT GOING OUT. 25 MARCH 2016 THE TOYOTA DEALERSHIP REPLACED THE "COMPUTER SUB-ASSY, H" FOR $458.52. 28 MARCH 2016, THE HEADLIGHT IS OUT AGAIN (NOTICED IT AGAIN IN MY DRIVEWAY).

Mileage: 137,507

THE HEADLIGHTS (HID) STOP FUNCTIONING INTERMITTENTLY. ONE OR THE OTHER OR BOTH WILL RANDOMLY SHUT OFF. THE LIGHTS WILL COME BACK ON IF THEY ARE TURNED OFF THEN ON AGAIN. THE ISSUE HAS BEEN HAPPENING FOR SEVERAL MONTHS.

WHILE DRIVING THE PASSENGER SIDE HEADLIGHT WENT OUT, I REPLACED THE BULB AND THE PROBLEM CONTINUED. IT TURNS OFF SHORTLY AFTER STARTING THE VEHICLE WETHER IT IS DRIVING OR SITTING, WHEN I TURN LIGHTS OFF AND ON AGAIN LIGHT WILL TURN BACK ON FOR A MOMENT AND TURN OFF AGAIN, THIS HAPPENS WHILE I AM DRIVING AND I AM AFRAID TO DRIVE IT AND BE PULLED OVER FOR NOT HAVING WORKING HEADLIGHTS.

I WAS DRIVING AT NIGHT ON THE FREEWAY 280 AND SUDDENLY BOTH HEADLIGHTS WENT OUT, IT WAS SO BLACK YOU COULDN'T SEE ANYTHING ON THE ROAD. TALK ABOUT SCARY, TRY DRIVING AT 65 MPH ON A ROAD THAT CURVES WHEN YOU ALL YO CAN SEE IS BLACK. I WAS ABLE TO JIGGLE THE SWITCH THE HEADLIGHT SWITCH OFF AND ON SEVERAL TIMES AND THE LIGHTS FINALLY CAME BACK ON. WITH MY HEART POUNDING I CONTINUED TO DRIVE HOME ONLY TO HAVE BOTH HEADLIGHTS AGAIN GO OUT TOGETHER. THIS HAPPENED 6-7MORE TIMES UNTIL I REACHED HOME. I WAS ACTUALLY SHAKING BY THE TIME I GOT OUT OF MY CAR. WHY WERE BOTH HEADLIGHTS MALFUNCTIONING AT THE EXACT SAME TIMES? I TOOK THE CAR TO THE DEALERS THE NEXT DAY AND AFTER INSPECTION THEY TOLD ME I SIMPLY NEEDED NEW HEADLIGHTS. I THOUGHT IT WAS AN ELECTRICAL MALFUNCTION, BUT THEY INSISTED THAT IT WAS JUST THE HEADLIGHTS GOING OUT AND THAT THIS HAPPENED ALL THE TIME. WHY WOULD THEY BE USING HEADLIGHTS THAT THEY KNOW BOTH GO OUT AT THE SAME TIME??THIS IS HIGHLY DANGEROUS. PEOPLE COULD HAVE A HEART ATTACK IF NOT AN ACCIDENT! I SPENT $500 TO REPLACE THE TWO HEADLIGHTS. HOWEVER, I JUST RECENTLY EXPERIENCE THE EXACT SAME PROBLEM OF BOTH HEAD LIGHTS GOING OUT. MY CAR IS AT THE DEALERS THIS VERY MOMENT FOR THE SAME PROBLEM. I HOPE MY 2005 PRIUS GETS RECALLED FOR THIS HEADLIGHT PROBLEM SO OTHER PEOPLE TO NOT HAVE TO EXPERIENCE THIS TRAMA AND DANGEROUS SITUATION. I WAS SURPRISED TO LEARN THAT THIS HEADLIGHT PROBLEM IS COMMON TO THE PRIUS. OUTSIDE OF THIS DANGEROUS HEADLIGHT PROBLEM I LOVE MY PRIUS.

Mileage: 135,000

DIGITAL DASHBOARD SOMETIMES IS COMPLETELY BLANK FOR EXTENDED PERIODS SO THAT I CAN'T SEE MY SPEED, FUEL LEVELS, ODOMETER, AND OTHER INFO. WHEN I START UP IT HAPPENS AND CONTINUES THE WHOLE TIME I AM DRIVING. IT IS CAUSING OTHER PROBLEMS RELATED TO THE HYDROLIC BRAKING SOMETIMES AS WELL WHEN THIS HAPPENS.

LAST NIGHT WHILE DRIVE 1.5 HOURS HOME, THE DRIVER'S SIDE HEADLIGHT WOULD SHUT OFF, AND IF I NOTICED AND FLIPPED THE LIGHTS OFF THEN ON, IT WOULD COME BACK ON. IF I DIDN'T NOTICE, THEN THE PASSENGER LIGHT WOULD ALSO GO OUT LEAVING ME IN DARKNESS. I BEGAN TIMING THE INTERVAL, AND IT CAME OUT TO BE INTERMITTENT BETWEEN ONE AND TWO MINUTES, REGARDLESS OF TERRAIN, SPEED OF VEHICLE, SMOOTH OR BUMPY ROADS, STRAIGHT OR CURVY ROADS, ETC.

ME AND MY FAMILY TRAVELING DOWN THE INTERSTATE AT 70 MPH IN THE DARK WHEN A TRACTOR TRAILER ALL OF A SUDDEN STARTED TO CHANGE LANES WHEN WE WERE DIRECTLY TO THE LEFT OF IT. LUCKILY THE LANE TO OUR LEFT WAS OPEN AND WE WERE ABLE TO QUICKLY CHANGE LANES TO AVOID COLLISION. IT TURNS OUT OUR 2005 PRIUS HEADLIGHTS WERE NOT WORKING AND THE TRUCK DID NOT SEE US. HAD TO TURN LIGHTS OFF THEN ON AGAIN TO GET THEM TO WORK. THE REST OF THE WAY HOME ONE LIGHT WOULD GO OUT, THEN THE OTHER WOULD GO OUT. HAD TO TURN SWITCH OFF THEN ON AGAIN TO GET THEM TO TURN ON AGAIN. THIS IS DEFINITELY A MAJOR SAFETY ISSUE WITH THIS CAR. WHY IS THERE NOT A RECALL.

Mileage: 150,000

PASSENGER SIDE HEADLIGHT IS INTERMITTENT. THIS HAS HAPPENED AT LEAST TWICE BEFORE AND I BELIEVE THE BULB AND SOME OTHER ELECTRONICS HAD TO BE REPLACED. THE DEALER CHARGES A HUGE AMOUNT FOR THIS REPAIR.

WE WERE ON THE OVERPASS GOING FROM HIGHWAY 87 TO US 101 NORTH IN SAN JOSE GOING ABOUT 70 MPH HEADING TO THE SAN FRANSISCO AIRPORT. IT WAS 8PM, AND VERY DARK. THE HEADLIGHTS JUST SHUT OFF, WHILE THE DASHBOARD INDICATOR SAID THAT THE LIGHTS WERE STILL ON. WE TRIED FRANTICALLY TRIED TURNING THE LIGHTS ON AND OFF AGAIN TO SEE IF THEY WOULD COME ON, AND THEY DIDN'T. WE TOOK THE NEXT EXIT AND STOPPED IN FRONT OF A HOTEL WERE WE COULD SEE THE HEADLIGHTS IN THE WINDOW, AND THEY WERE OFF. WE TURNED THE CAR OFF, COUNTED TO 10, THEN TURNED THE CAR BACK ON. THE LIGHTS CAME BACK ON. WE TURNED ON THE FOGLIGHTS IN CASE THE HEADLIGHTS TURNED OFF AGAIN. THEY STAYED ON ALL THE WAY TO THE AIRPORT AND ALMOST ALL THE WAY HOME. THEY TURNED OFF FOR ABOUT 1 MILE, AND THEN TURNED BACK ON.

Mileage: 170,000

HEAD LIGHT WILL INTERMITTENTLY GO OFF. I CAN TURN THE LIGHT SWITCH TO OFF AND THEN BACK ON AND THE HEADLIGHT WILL COME BACK ON. USUALLY THIS HAPPENED ON A STREET OR HIGHWAY WHEN THE CAR IS IN MOTION AND LIGHTS ARE SWITCH ON. THIS HAPPENS OFF AND ON WHEN THE CAR IS BEING DRIVEN. USUALLY IT IS THE LEFT HEADLIGHT, BUT OCCASIONALLY THE RIGHT HEADLIGHT GOES OFF AS WELL. THIS HAS BEEN HAPPENING FOR SEVERAL MONTHS. THE TOYOTA DEALER QUOTES $500.00 TO MAKE REPAIRS! I DID RESEARCH ON INTERNET AND FOUND THAT THIS PROBLEM IS PRETTY COMMON FOR CERTAIN YEARS OF THE TOYOTA PRIUS AUTOMOBILES, 2005 INCLUDED.

SINCE SEPTEMBER OF 2014 I HAVE HAD ISSUES WITH THE DASHBOARD LIGHTS. THEY HAVE BECOME DIMMER AND DIMMER. THEN DURING THE WEEK OF 8/24/15, I STARTED MY CAR AND THE DASHBOARD LIGHTS CAME ON, BUT WHEN I TURNED ON THE HEADLIGHTS, ALL DASHBOARD LIGHTS WENT BLACK. I HAD TURN SIGNAL LIGHTS, BUT NOTHING ELSE UNLESS I TURNED OFF THE HEADLIGHTS. THIS WAS EXTREMELY DANGEROUS AS I WAS DRIVING HOME AFTER DARK. I HAD NO IDEA HOW FAST I WAS GOING, WHAT GEAR I WAS IN, IF I HAD ENOUGH GAS TO GET HOME, ETC., ETC. THE NEXT MORNING I TOOK A 20-MILE DRIVE AND WHEN I STOPPED, I COULD NOT GET THE CAR TO SHUT OFF BY PUSHING THE IGNITION BUTTON. I TRIED MULTIPLE TIMES AND THE ENGINE FINALLY TURNED OFF, BUT THE DISPLAY PANEL WAS STILL DIMLY LIT. I THEN DROVE DIRECTLY TO THE DEALERSHIP TO HAVE WHATEVER WAS WRONG REPAIRED. AFTER A MECHANIC CHECKED IT OUT, IT WAS DETERMINED THE COMPUTER NEEDED TO BE REPLACED AND THEY HAD TO ORDER THE PART. THIS IS NOT AN ITEM THAT IS NORMALLY SERVICED AND I HAVE NO CLUE IF THE DEALERSHIP CHECKS IT DURING A SERVICING OF THE CAR. SO I WONDERED IF THERE WAS A RECALL ON IT. IN CHECKING ON THIS WEBSITE I FIND I AM NOT THE ONLY PERSON WHO HAS HAD THIS PROBLEM AND THAT I THOUGHT THERE WOULD BE A RECALL ON IT. WHEN I PICKED UP MY CAR I ASKED ABOUT THE RECALL AND I WAS GIVEN PAPERWORK STATING IT WAS A "WARRANTY ENHANCEMENT PROGRAM" FOR "9 YEARS WITH NO MILEAGE LIMITATION FROM THE DATE OF FIRST USE OR BEFORE SEPTEMBER 30, 2013". LETTERS WERE SENT OUT TO PRIUS OWNERS OF CARS FROM 2004 TO CERTAIN 2009 MODELS. I NEVER RECEIVED A LETTER AND AM VERY CONCERNED IF TOYOTA KNEW THERE WAS A PROBLEM WHY DIDN'T THEY NOT DO JUST A "WARRANTY ENHANCEMENT PROGRAM" BUT A RECALL? THEY WOULD THAT EVENTUALLY ALL CARS WOULD HAVE THIS PROBLEM AND IT SHOULD BE REPLACED. THIS IS AN EXTREME SAFETY ISSUE!

I HAVE BEEN EXPERIENCING SOME PROBLEMS WITH MY HEADLIGHTS. I CHANGED THE BULB AND A MONTH LATER THE LIGHT STOPPED WORKING AGAIN. I TOOK IT TO THE DEALERSHIP THEY BLAMED IT ON THE BULB, I TRIED TO RETURN THE BULB TO THE STORE AND THEY TESTED IT AND SAID EVERYTHING WAS OK WITH THE BULB SO IT HAD TO BE THE HEADLIGHTS. I'M ALSO HAVING PROBLEMS WITH THE DASHBOARD LIGHTS. THE SPEEDOMETER AND GAS GAGE COMPLETELY FAILED. AT THE SAME TIME I WAS TOLD MY ABS BRAKE SYSTEM NEEDS TO BE REPLACED! THIS IS TOO MUCH HAPPENING AT THE SAME TIME AND I HAVE TO PAY FOR ALL OF IT OUT OF POCKET.

HEADLIGHT ON THE DRIVER SIDE KEEPS TURNING OFF EVERY COUPLE OF MINUTES. THE ONLY WAY TO TURN IT BACK ON IS TO FLIP THE HEADLIGHT SWITCH. IT LOOKS LIKE THIS IS A DEFECT IN MANY TOYOTA PRIUS 2005 MODELS. I WOULD LIKE THE DEALER TO FIX THE ISSUE EVEN IF TYE CAR IS BEYOND THE MANUFACTURER WARRANTY AS THIS IS CLEARLY A MANUFACTURING DEFECT.

THE HEADLIGHTS ON MY 2005 TOYOTA PRIUS GO OUT ON A MUCH TO FREQUENT BASIS. I HAVE REPLACED BOTH HEADLIGHTS MULTIPLE TIMES. THIS LAST TIME, I TOOK THE CAR TO THE DEALERSHIP (NORTHSHORE TOYOTA) TO ASK IF THEY COULD CHECK THE HEADLIGHTS. I THOUGHT IT COULD BE A BAD CONNECTION. THEY CHECKED THE HEADLIGHTS AND SAID THEY BOTH NEEDED REPLACING, ALTHOUGH ONE WAS WORKING WHEN I BROUGHT THE CAR IN FOR SERVICE. THEY DID NOT MENTION ANYTHING ABOUT AN ISSUE WITH THE HEADLIGHTS, AND GLADLY TOOK OUR MONEY FOR REPLACING THE LIGHTS. UPON FURTHER RESEARCH, I LEARNED THAT THIS IS A PROBLEM WITH HEADLIGHTS ON TOYOTA PRIUS. I FEEL THIS IS A SAFETY ISSUE AND SHOULD BE ADDRESSED BY THE MANUFACTURER. *TR

ORIGINALLY THE PASSENGER HEADLIGHT WOULD SHUT OFF RANDOMLY. I WOULD FLICK THE LIGHTS ON AND OFF AND IT WOULD TURN BACK ON. THEN THIS PAST NEW YEARS EVE BOTH HEADLIGHTS TURNED OFF AND I FLICKED THE LIGHTS ON AND OFF AND THAT DID NOT WORK. I SHUT OFF THE HEADLIGHTS WITH THE SWITCH FOR A FEW SECONDS AND LUCKILY THEY TURNED ON AGAIN. HOWEVER THE KEPT ON SHUTTING OFF MORE CONSISTENTLY. FIRST THE PASSENGER THEN BOTH. THIS IS RIDICULOUS. AND THE CAR WAS NOT SAFE TO DRIVE. I REPLACED BOTH HEADLIGHT BULBS AT MY OWN EXPENSE. THE BULBS WORKED GREAT FOR 2 DAYS. NOW BOTH HEADLIGHTS WILL NOT STAY ON FOR MORE THAN 45 SECONDS. MY 16 YR OLD SON ALSO DRIVES THIS CAR AND THIS IS UNACCEPTABLE. IF SOMETHING WERE TO HAPPEN TO HIM BECAUSE OF THIS KNOWN DEFECT THAT TOYOTA IS NOT WILLING TO FIX. THIS IS TERRIBLE! FIX THIS PROBLEM! NEW BULBS IS NOT THE FIX. THERE IS SOMETHING ELSE SERIOUSLY WRONG HERE. *TR

I AM THE ORIGINAL OWNER OF MY PRIUS AND IT HAS WORKED WONDERFULLY EXCEPT FOR HAVING TO REPLACE THE HEADLIGHTS. ABOUT 4 YEARS AGO I HAD AN ACCIDENT AND THE FRONT BUMPER AND DRIVER SIDE HEADLIGHT WAS REPLACED. IT IS NOW FLICKERING AND TURNS OFF. THE PASSENGER SIDE HEADLIGHT WAS ALSO REPLACED 4-5 YEARS AGO AND IT DIED ABOUT 6 MONTHS AGO. THIS IS A SERIOUS PROBLEM SINCE THE HEAD LIGHT FLICKERS AND DIES WHILE DRIVING. I ALMOST DROVE OFF THE ROAD ON A SIDE STREET BECAUSE I COULD NOT SEE. *TR

INTERMITTENT FAILURE OF HEADLIGHT (LEFT AND RIGHT, THOUGH NOT SIMULTANEOUSLY). PROBLEM CAN BE TEMPORARILY CORRECTED BY TURNING HEADLIGHTS OFF, THEN ON.

THE FIRST TIME HAPPENED ABOUT A YEAR AGO AND THE ISSUE GETS WORSE. I TOOK THE CAR INTO THE SHOP TO REPLACE A HEADLIGHT AS I THOUGHT IT HAD BURNT OUT. WHEN I ARRIVED, THE PASSENGER SIDE LIGHT WAS WORKING AGAIN. THE ISSUE HAS BEEN SO BAD NOW THAT BOTH HEADLIGHTS MAY TURN OFF WITH NO WARNING AND CAUSE COMPLETE DARKNESS WHILE ON THE ROAD. FROM WHAT THE SHOP TOLD ME IS THAT I WILL HAVE TO POSSIBLY REPLACE THE HID HEADLAMP CPU IN ORDER TO ENSURE NO FURTHER ISSUES. THIS IS A SEVERE SAFETY ISSUE THAT SEEMS TO PLAGUE THE MAKE AND MODEL OF TOYOTAS. *TR

OUR NEIGHBOR NOTICED THAT OUR RIGHT HEADLIGHT WAS OUT. IT PROVED TO BE INTERMITTENT, GOING ON AND OFF AT UNPREDICTABLE INTERVALS BUT GETTING WORSE WITH TIME. WE HAD BOTH HEADLIGHT BULBS AND MODULES REPLACED, A PROCEDURE THAT REQUIRED THE REMOVAL OF THE FRONT BUMPER, AMONG OTHER THINGS, AND COST $1,212.98 AT AN INDEPENDENT GARAGE. WE SUSPECTED THAT THE COST WOULD HAVE BEEN EVEN HIGHER AT A TOYOTA DEALERSHIP. NOW, BEGINNING ON OR ABOUT OCTOBER 23, 2014, THE SAME PROBLEM HAS RECURRED, THIS TIME INVOLVING THE LEFT HEADLIGHT. GIVEN THE HIGH COST OF REPAIR AND THE FACT THAT, OBVIOUSLY, THE FIX IS ONLY TEMPORARY, WE HAVE NOT HAD THE HEADLIGHTS REPLACED AGAIN BUT ARE ATTEMPTING TO AVOID DRIVING THE VEHICLE AT NIGHT OR IN BAD WEATHER. GIVEN THE APPARENT FREQUENCY THAT PRIUS OWNERS HAVE REPORTED THIS SAME PROBLEM, MY WIFE AND I DO NOT UNDERSTAND WHY TOYOTA HAS NOT DEVELOPED A GENERIC FIX AND ISSUED A RECALL. *TR

EVERY SINCE THE REPAIR THE HEADLIGHTS HAVE BEEN GOING OUT FOR NO APPARANT REASON. AT FIRST JUST THE RIGHT HEADLIGHT, NOW BOTH LIGHTS SHUT OFF AT THE SAME TIME AND I HAVE TO TURN THEM OFF AND BACK ON TO GET THEM TO EMIT LIGHT. THE DEALER SAID IT WAS THE HEADLIGHTS THEMSELVES BUT WHY DO BOTH OF THEM GO OUT AT THE SAME TIME AND WHY DO THEY COME BACK ON AND CONTINUE TO WORK. AT FIRST THIS OCCURED MAYBE ONCE A DAY BUT IT IS OCCURING FREQUENTLY. I DO NOT THINK IT IS THE BULBS BECASUE THEY KEEP SHUTTING OFF AT THE SAME TIME WHICH SUGGEST IT IS SOMETHING ELSE. *TR

IN MID JUNE 2012, WHILE DRIVING ON THE FREEWAY I NOTICED THE LEFT SIDE HEADLIGHT WAS NOT ON, INITIALLY I THOUGHT THE BULB WAS BAD SINCE I HAD ALREADY HAD TO REPLACE THE RIGHT ONE. I HAD PLANED TO TAKE THE CAR TO ELMORE TOYOTA OF HUNTINGTON BEACH, CA TO HAVE THE BULB REPLACED BUT THE FOLLOWING DAY THE LIGHT WAS WORKING. AFTER A FEW DAYS IT STARTED HAPPENING AGAIN. I FOUND THAT IF I TURNED THE LIGHTS ON AND OFF THE HEADLIGHT WOULD COME BACK ON, I HAVE HAD THIS PROBLEM FOR OVER A YEAR NOW. TODAY I DECIDED TO TAKE THE CAR TO THE DEALER'S SERVICE DEPARTMENT, NOW THEY CAN'T SEEM TO TELL ME WHAT IS THE TRUE NATURE OF THE PROBLEM, ALL THEY WANT TO DO IS SELL ME A NEW BULB. AFTER DOING SOME RESEARCH ON MY OWN I NOW UNDERSTAND THAT THIS HAS BEEN AN ONGOING PROBLEM SINCE 2007 AND THAT THE NHTSA HAS INVESTIGATED THIS AND HAS DECIDED THAT THIS IS NOT A SAFETY ISSUE. I WOULD LIKE TO SEE IF THE PERSONS RESPONSIBLE FOR THIS DECISION WOULD LIKE TO GO ON A LONG NIGHT DRIVE WITH ME ON A MOUNTAIN ROAD. RIGHT NOW I WANT TO OFFICIALLY FILE A COMPLAINT ABOUT THIS PROBLEM, MY 2005 TOYOTA PRIUS IS UNSAFE TO DRIVE BECAUSE THE HEADLIGHTS ARE NOT DEPENDABLE AND THERE IS NO TELLING WHEN THEY WILL STOP WORKING. *TR

Mileage: 105,000

BOTH OF MY PRIUS HEADLIGHTS WENT OFF, FOR NO APPARENT REASON, WHILE DRIVING DOWN A BUSY HIGHWAY. FLICKING THEM OFF AND THEN BACK ON BROUGHT THEM ON AGAIN, BUT THIS IS A DANGEROUS SITUATION. THIS HAS HAPPENED ONE MORE TIME SINCE THEN. THIS COULD CAUSE A SERIOUS ACCIDENT. TOYOTA IS UNABLE TO ISOLATE THE PROBLEM. THE COMPANY WANTS TO REPLACE THE BULBS, BUT THIS DOESN'T FIX THE PROBLEM, ACCORDING TO MANY OTHER PEOPLE WHO HAVE HAD THIS PROBLEM. REPLACING THE BULBS OR ADJACENT PARTS CAN COST HUNDREDS OF DOLLARS, WHICH IS NOT SUSTAINABLE. IT SEEMS THAT A RECALL IS IN ORDER. *TR

THE HEADLIGHT OPERATION BECAME ERRATIC. SOMETIMES ONE WOULD WORK AND SOMETIMES THE OTHER ONE WOULD BE THE ONLY ONE TO FUNCTION. SOMETIMES NEITHER HEADLIGHT WOULD COME ON. REPEATED OPERATION OF THE HEADLIGHT SWITCH EVENTUALLY WOULD GET ONE OR BOTH HEADLIGHTS TURNED ON. THE LIGHT BULBS WERE REPLACED IN 2012 AND AGAIN IN 2013. THERE WAS LITTLE OR NO CHANGE IN PERFORMANCE. WHEN I HAVE ASKED MY TOYOTA DEALER'S SERVICE DEPARTMENT ABOUT IT, THEY SIMPLY SAID THEY WEREN'T AWARE OF ANY PROBLEM. I CANNOT BELIEVE THAT IS TRUE. THIS IS A MUCH DISCUSSED AND NOT UNCOMMON PROBLEM. WE ARE ALWAYS CONCERNED THAT THE HEADLIGHTS MIGHT FAIL WHILE WE WERE DRIVING. THIS HAS NOT HAPPENED YET, BUT I HAVE NO CONFIDENCE IN THE HEADLIGHT RELIABILITY. *TR

ENTERING I-25 SOUTHBOUND ON DARK NIGHT AND THE HEAD LAMPS WENT OUT. TURNED THE SWITCH OFF AND THEN ON, THEY CAME BACK ON AND THEN WENT RIGHT OFF. RE-TRIED THE SWITCH AND THEY CAME BACK ON.. FAILED AGAIN ABOUT FIVE MILES FURTHER SOUTH ON THE I-25 HIGHWAY. TURNED THEM OFF AND BACK ON AND THEY CAME BACK ON AND STAYED UNTIL I GOT BACK HOME. THE BULBS MUST BE GOOD FOR THEM TO COME BACK ON. POSSIBLE BAD SWITCH OR COMPUTER CHIP THAT CONTROLS THE AUTOMATIC CIRCUITRY. THIS WAS VERY SCARY BECAUSE WE HAD HIGH SPEED TRAFFIC THAT COULDN'T SEE US BECAUSE WE HAD NO LIGHTS VISIBLE. THERE WAS CONSTRUCTION IN THE AREA WHICH MADE IT ALL THE MORE TENSE NOTE:THE VEHICLE MAKE NAME BOX ABOVE DOES NOT PULL DOWN. *TR

MY DRIVERS SIDE HEADLIGHT FLICKERS THEN GOES OUT. I WAS ABLE TO GET IT ON AGAIN BY MANUALLY TURNING THE SWITCH ON AND OFF. THEN IT WILL HAPPEN AGAIN. I REPLACED THE HEADLIGHT ($175 FOR THE PART ALONE) IN MAY OF 2012. IT IS NOW MARCH OF 2014 AND THE SAME LIGHT BEGAN DOING IT AGAIN, FLICKERING. I WAS ABLE TO GET IT TO GO ON BY MANUALLY SWITCHING IT ON. NOW IT IS OUT AGAIN. *TR

AFTER THAT, IT IS NOW BOTH HEADLIGHTS GO OUT SPONTANEOUSLY, AND THEREFORE SOMETIMES AT THE SAME TIME, LEAVING IN THE DARK AT NIGHT ON THE ROAD.

FOR SEVERAL MONTHS, THE DRIVER'S SIDE HEAD LIGHT OF MY 2005 TOYOTA PRIUS WOULD SPONTANEOUSLY BLINK OUT. BECAUSE IT WAS BLINKING OUT AND COMING BACK ON, I TOLD THE DEALER I SUSPECTED SOME KIND OF WIRING PROBLEM, BUT WAS ASSURED THAT THIS WAS A COMMON PROBLEM WITH THE PRIUS HEAD LAMPS. I WAS THEN TOLD THAT WE HAD THE "SPECIAL" HID LAMPS THAT COST $150 APIECE, PLUS $75+ IN LABOR BECAUSE OF HOW COMPLICATED THEY WERE TO REPLACE. WHEN I ASKED HOW LONG IT WOULD TAKE FOR THIS LABOR INTENSIVE $75+ REPAIR, I WAS TOLD 15 MINUTES (IN OTHER WORDS, I WOULD BE CHARGED $300/HOUR FOR LABOR). AFTER BEING REASSURED AGAIN THAT REPLACING THE HEAD LAMP WOULD SOLVE THE PROBLEM, I AGREED TO MOVE FORWARD WITH THE REPAIR. FAST FORWARD 2 WEEKS, AND THE DRIVER'S HEADLAMP WAS ONCE AGAIN BLINKING ON AND OFF. THE DEALERSHIP SEEMED COMPLETELY UNSURPRISED BY THE PERSISTENCE OF THIS PROBLEM, AND AGREED TO A "COURTESY RECHECK." THEY THEN INFORMED ME THAT SINCE THE $225 HEAD LAMP REPAIR THEY TALKED ME INTO DIDN'T SOLVE THE PROBLEM, THE CAUSE OF THE BLINKING WAS "DEFINITELY" THE ECU (THE COMPUTER THAT CONTROLS THE HEAD LAMP), AND IT WOULD COST ~$700 TO REPLACE THIS COMPONENT. AT NO POINT DID THE DEALER ACKNOWLEDGE THAT THE HID LAMPS AND ASSOCIATED ECUS HAVE BEEN DEFECTIVE IN HUNDREDS OF THOUSANDS OF PRIUS CARS, AS I QUICKLY LEARNED ONLINE. *TR

Mileage: 92,000

INITIALLY IT WAS THE DRIVERS SIDE HEADLIGHT THAT WENT OUT. TURNING THE SWITCH OFF AND ON RESET THE HEADLIGHT TO ILLUMINATE AGAIN. I TOOK THE VEHICLE TO MY MECHANIC TO REPLACE THE DRIVER SIDE HEADLIGHT. THE MECHANIC SAID THE HEADLIGHTS WORKED FINE AND TO CONTINUE TO DRIVE UNTIL IT FAILED OR OTHER ISSUE REPORTED. AFTER A COUPLE WEEKS THE ISSUE PROGRESSED TO BOTH HEADLIGHTS GOING OUT. TURNING OFF AND ON WOULD RESTORE ILLUMINATION. THIS WOULD HAPPEN RANDOMLY SOMETIMES RECURRING AGAIN AFTER 5-10MINUTES. FINALLY THE PASSENGER SIDE HEADLIGHT WENT OUT COMPLETELY AND WOULD NOT ILLUMINATE. I TOOK THE VEHICLE TO MY MECHANIC AND HAD THE PASSENGER SIDE HEADLIGHT REPLACE. A FEW DAYS LATER THE DRIVERS SIDE HEADLIGHT STARTED TURNING OFF AGAIN. MY NEXT STEP IS TO TAKE THE VEHICLE INTO THE DEALERSHIP AND SEE IF THEY CAN FIX THE ISSUE. I'VE RESEARCHED THE ISSUE AND HAVE SEEN PLENTY OF COMPLAINTS REGARDING THIS ISSUE. I'M CONCERNED THIS IS A PERSISTENT DEFECT, LIGHT SHUTTING OFF RANDOMLY, WILL HAVE A DEVASTATING EFFECT ONCE MY LUCK RUNS OUT. *TR

THE HID HEADLIGHTS WILL OCCASIONALLY GO OUT. OVER TIME I REALIZED THAT BY TURNING THE LIGHTS OFF AND ON, THE LIGHTS CAME BACK ON. WHILE DRIVING AT NIGHT, THIS EVENT CAN HAPPEN AS OFTEN AS EVERY COUPLE MINUTES. SOMETIMES IT MAY NOT OCCUR FOR AN HOUR. BUT THERE IS NO RHYME OR REASON AS TO THE FREQUENCY OF LOSING THE LIGHT. MAYBE 3 OR 4 TIMES OVER THE LAST 2 YEARS BOTH HEADLIGHTS TURNED OFF AT ONCE. HAD I BEEN ON AN INTERSTATE AT THE TIME OR IN INCLEMENT WEATHER, IT WOULD HAVE BEEN MUCH MORE DANGEROUS AND LIFE THREATENING. LOSING THE LIGHT FROM A BULB CAN OCCUR TO EITHER HEADLIGHT. ALTHOUGH IT SEEMS TO OCCUR WITH ONE BULB OR THE OTHER FOR A PERIOD OF TIME. IN OTHER WORDS, ON A NIGHT'S DRIVE, IT'S USUALLY ONE BULB THAT WILL OFTEN GO OUT ON THAT NIGHT. THE NEXT EVENING IT MAY BE THE OTHER HEADLIGHT. THE LOCAL TOYOTA SERVICE GARAGE CHARGES ABOUT $175 EACH FOR THE HID LIGHTBULBS AND ANOTHER $95 FOR THE INSTALLATION. LOOKING AT OPINIONS ON LINE CONCERNING THIS PRIUS HEADLIGHT PROBLEM, IS THE VIEW THAT REPLACING THE BULB IS NOT THE ISSUE. THE PROBLEM IS WITHIN THE COMPUTER SYSTEM OF THE CAR. THE PRICE OF REPLACING THE BULBS COMBINED WITH THE POSSIBILITY THAT LIGHT REPLACEMENT MAY NOT SOLVE THE PROBLEM, KEEPS ME FROM SPENDING THE MONEY AND INSTEAD KEEPS ME FLICKING THE LIGHTS OFF AND ON WHEN NEEDED. GIVEN THE EXTREME POTENTIAL DANGER OF THIS DEFECT, IT SEEMS THAT TOYOTA OWES IT TO THEIR CUSTOMERS TO GET TO THE BOTTOM OF THIS PROBLEM. AND CREATE A FIX. *TR

WHILE CROSSING THE BRIDGE OF THE GODS, CASCADE LOCKS, OREGON AT ABOUT 9PM THE TOLL COLLECTOR TOLD ME MY DRIVERS SIDE HEADLIGHT WAS OUT. I TURNED ON MY HIGH BEAMS AND HAD TWO LIGHTS ON. ON LOW BEAM ONLY ONE LIGHT...DRIVING WITH HIGH BEAMS AT NIGHT IS DANGEROUS TO OTHER DRIVERS ON THE ROAD; DRIVING WITH ONE OR NO HEADLIGHTS AT NIGHT IS ALSO DANGEROUS. THE NEXT DAY I TURNED ON THE LIGHTS (LOW BEAM) AND THEY WERE BOTH ON AGAIN....I CHECKED PRIUSCHAT.COM FORUM AND READ 56 PAGES OF PRIUS OWNERS WITH THE SAME PROBLEM...THAT EITHER ONE OR BOTH HEADLIGHTS WILL TURN OFF INTERMITTENTLY AND RANDOMLY, OFTEN AT NIGHT. I CALLED TOYOTA CUSTOMER SERVICE AND [XXX] THE SERVICE REP I TALKED TO LOOKED UP MY CAR AND SAID THERE IS NO REMEDY TOYOTA RECOMMENDS OTHER THAN TAKE IT TO A DEALER AND HAVE IT "REPAIRED" FOR APPROXIMATELY $800-1200 DOLLARS. FURTHER, READING ABOUT THE PRIUS OWNERS HEADLIGHT EXPERIENCES POSTED ON THE FORUM SUGGESTS THAT MORE THAN OFTEN THIS VERY DANGEROUS VEHICLE DEFECT IS NOT "REPAIRED" BY WHAT THE DEALER SERVICE DEPARTMENT DOES AND THE LIGHTS CONTINUE TO TURN OFF RANDOMLY..AS A RETIRED POLICE OFFICER I CONSIDER THIS PRODUCT DESIGN DEFECT TO BE EXTREMELY DANGEROUS AND THAT TOYOTA CORP.

THE RIGHT HEADLAMP WORKS INTERMITTENTLY AND HAS BEEN FOR SOME TIME AND LATELY THE LEFT IS JOINING IN. I HAVE ASKED ABOUT THIS NUMEROUS TIMES OVER THE PAST COUPLE OF YEARS WHEN IN THE DEALERSHIP FOR OTHER SERVICES. IT ISN'T A PROBLEM ANY TIME I HAVE BEEN IN THEIR PRESENCE; BUT THEY NOTED IT IN MY FILE. LIKEWISE, AS I CROSS MY FINGERS YEARLY, THEY HAVE BOTH BEEN WORKING DURING INSPECTION. THOUGHT I WAS CRAZY UNTIL I SEE TONS OF COMPLAINTS ON THE INTERNET AS WELL AS INFO THAT YOU HAD AN INVESTIGATION BUT CLOSED IT SAYING THIS ISN'T A SAFETY ISSUE. JUST WANT IT TO GO ON RECORD WITH YOU AS WELL BECAUSE IF SOMETHING HAPPENS, YOU AND TOYOTA WILL BE SUED. THIS IS OBVIOUSLY A PROBLEM WITH UPWARDS OF 2K PEOPLE (THAT YOU KNOW OF) AND SEE NO SAFETY ISSUE IN SOMETHING AS IMPORTANT AS LIGHTING? CARS DO NOT PASS INSPECTION WITH INADEQUATE LIGHTING AND REQUIRE REPLACEMENT; BUT, YOU SEE NO VALIDITY IN A LIGHTING ISSUE THAT THE CONSUMER IS UNABLE TO SOLVE BY REPLACEMENT OF THE LIGHTING UNIT??

LAST FRIDAY NIGHT BOTH RIGHT AND LEFT HEADLIGHTS BURNED OUT WITHIN FIVE MINUTES OF ONE ANOTHER. THANKFULLY I COULD LIMP HOME WITH THE HELP OF STREET LIGHTS. I DISCOVERED TODAY AT TOYOTA DEALERSHIP THAT THE COST OF TWO NEW HID OSRAM XENARC D2R 35 W 66050 ($ 175/BULB) AND LABOR ($ 113/HR) PLUS SALES TAX WAS $ 467.31. I CHECKED THE COST OF THE HID BULBS ONLINE. AMAZON OFFERS A PAIR OF THESE BULBS FOR $ 159.99 PLUS FREE SHIPPING. TOYOTA'S GENUINE PART MARK UP IS AN ASTOUNDING 217% IN THIS COMPARISON. FURTHER, THE TOYOTA PARTS/SERVICE SAID THAT THEY NEED TO TAKE OFF THE BUMPER - UNLIKE THE OWNER'S MANUAL INSTRUCTIONS FROM THE SIDE OF THE HEADLIGHTS - TO REPLACE THE BULBS. TOYOTA HEADLIGHTS CAN BE DANGEROUS IF THEY BURN OUT SIMULTANEOUSLY AND REPLACEMENT COST IS RIDICULOUS AT THE DEALERSHIP! *TR

I HAVE TO DRIVE AND LOOK AT THE REFLECTION OF MY CAR ON THE SIDE OF ANOTHER CAR TO SEE IF MY LIGHT IS ONE OR NOT. WHEN I RESET THE LIGHT, PEOPLE THINK I AM FLASHING THEM TO PULL OVER. I HAVE BEEN PULLED OVER FOR THE LIGHT OUT AND I WAS ABLE TO DEMONSTRATE TO THE PEACE OFFICER THAT I CAN RESET THE LIGHT BY TURNING IT OFF AND ON, HE TOLD ME TO TAKE CARE OF IT, YET THERE ARE NO ANSWERS OR A FIRM FIX.

STARTING OVER A YEAR AGO AND OCCURRING EVERY TIME NEEDED,THE HEADLIGHT ON THE PASSENGER SIDE SPORADICALLY GOES OUT. IT CAN HAPPEN ZERO TO MULTIPLE TIMES DURING A SINGLE USE OF THE CAR, SOMETIMES UP TO EVERY MINUTE AND A HALF WHILE DRIVING. TURNING THE HEADLIGHTS OFF AND BACK ON AGAIN CAUSE BOTH HEADLIGHTS TO COME BACK ON. AS FAR AS WE KNOW, THIS DID NOT START HAPPENING UNTIL AFTER A MAINTENANCE VISIT AND WAS STOPPED BY A STATE PATROL OFFICER. CONVERSATIONS WITH OTHER PRIUS OWNERS, REPLACING THE HEADLIGHT DOES NOT SEEM TO RESOLVE THIS ISSUE. AT +$350 TO CHANGE THE HEADLIGHT AT THE DEALER, I AM HESITANT TO SPEND MONEY ON SOMETHING THAT WILL NOT RESOLVE THE ISSUE. WHILE WE HAVE HAD NO OTHER TROUBLES WITH THIS CAR AND LOVE THE CAR, THIS RECURRING ISSUE HAS CAUSED US TO HESITATE DRIVING THE CAR AT NIGHT.

STARTING IN APPROXIMATELY MARCH AND OCCURRING DAILY THROUGH PRESENT DAY, ONE OR BOTH HEADLIGHTS SPORADICALLY GO OUT. WE STARTED NOTICING THIS IN MARCH WHEN DRIVING AT NIGHT. OUR OWN TESTS INDICATE THAT IT CAN HAPPEN WHEN THE CAR IS AT A COMPLETE STANDSTILL OR AT ANY SPEED. IT CAN HAPPEN ZERO TO MULTIPLE TIMES DURING A SINGLE USE OF THE CAR, SOMETIMES UP TO EVERY MINUTE AND A HALF WHILE DRIVING. TURNING THE HEADLIGHTS OFF AND BACK ON AGAIN CAUSE BOTH HEADLIGHTS TO COME BACK ON. AS FAR AS WE KNOW, THIS DID NOT START HAPPENING UNTIL THIS LAST MARCH.

1. DRIVER'S SIDE HID-TYPE HEADLIGHT WENT OUT WHILE DRIVING AT NIGHT. WENT ON & OFF INTERMITTENTLY FOR SEVERAL DAYS. REQUIRED A REPLACEMENT HEADLIGHT COMPUTER AND BULB.

BOTH HID HEADLIGHTS WENT OUT AT THE SAME TIME. I CAN TOGGLE THE LIGHT SWITCH OFF AND ON AND ONE OR BOTH LIGHTS CAME BACK ON. THEN WENT OUT AGAIN WITHIN A FEW SECONDS TO A MINUTE, OVER AND OVER. MAKES NO DIFFERENCE IF CAR IS NOT MOVING AT ALL OR GOING 70 MPH. I WAS ABLE TO DRIVE THE 15 MILES HOME AT NIGHT WITHOUT INCIDENT. WENT TO DEALER NEXT DAY AND THEY SAY ALL THAT IS WRONG IS THAT THE HEADLIGHTS ARE BURNED OUT. ESTIMATE TO REPLACE BOTH IS $474.31. I DO NOT BELIEVE THAT THEY WOULD BURN OUT AT EXACTLY THE SAME TIME. AND IF THEY ARE BURNED OUT THEN WHY DO THEY COME BACK ON AND OFF. I HAVE DONE RESEARCH AND FOUND THE CLASS ACTION SETTLEMENT FOR 2006-2009 MODELS. I ALSO FOUND THAT YOU HAVE HAD HUNDREDS OF COMPLAINTS ABOUT THE 2005 MODEL YET YOU HAVE NOT CONSIDERED THIS A SAFETY MATTER. I DISAGREE. EVEN IF YOU DON'T HELP ME, I WANT MY COMPLAINT INCLUDED IN YOUR DATABASE. *TR

I WAS DRIVING HOME ON THE HIGHWAY AT NIGHT WHEN BOTH HEADLIGHTS SHUT OFF. THE RIGHT HEADLIGHT HAS BEEN TURNING OFF PERIODICALLY, BUT THIS IS THE FIRST TIME BOTH LIGHTS HAVE GONE OUT. BY TURNING THE LIGHTS OFF AND THEN ON, THE HEADLIGHTS RETURNED TO WORKING ORDER. THIS IS A PERSISTENT PROBLEM, WHICH BOTH TOYOTA AND NHTSA KNOW ABOUT. REPLACING THE LIGHTBULB APPEARS TO BE ONLY A VERY TEMPORARY, AND COSTLY, SOLUTION. *TR

THE PASSENGER SIDE HID HEADLIGHT WENT OUT. THE NEXT TIME I USED THE CAR, THE HEADLIGHT WAS WORKING AGAIN. SINCE THE FIRST OCCURRENCE, EITHER HEADLIGHT HAS GONE OUT INTERMITTENTLY (I HAVE NOT BEEN AWARE THAT BOTH HAVE GONE OUT AT THE SAME TIME). EACH TIME, THE HEADLIGHTS ARE FOUND TO BE WORKING AGAIN LATER. I DON'T KNOW HOW OFTEN THE PROBLEM IS OCCURRING. I DON'T DO A LOT OF NIGHT DRIVING, BUT I KEEP MY LIGHTS ON ALL THE TIME. I SUSPECT THERE ARE MANY DAYLIGHT FAILURES THAT GO UNNOTICED. *TR

MY 2005 PRIUS BEGAN TO HAVE PROBLEMS WITH THE DRIVER'S SIDE HEADLIGHT. WHEN I FIRST TURN MY LIGHTS ON, THE HEADLAMP WORKS, BUT AFTER A FEW MINUTES OF DRIVING, IT GOES OUT. SWITCHING TO HIGH BEAMS DOESN'T MAKE ANY DIFFERENCE, BUT IF I TURN OFF MY LIGHTS AND TURN THEM RIGHT BACK ON, THE HEADLAMP WORKS FOR A SHORT WHILE. I HAVE RESEARCHED THIS ON PRIUS FORUMS, AND IT IS A VERY COMMON PROBLEM. THE DEALER WANTS $2600 TO FIX IT. I THINK IT IS A MANUFACTURING DEFECT AND SHOULD BE RECALLED AND FIXED AT NO CHARGE. *TR

Mileage: 61,854

WHEN I STARTED MY 2005 TOYOTA PRIUS, I GOT A WARNING ON THE DASHBOARD AND THE MULTI-FUNCTION DISPLAY THAT THE AUTOMATIC HEADLIGHT LEVELING SYSTEM HAD MALFUNCTIONED. THIS IS A SAFETY FEATURE THAT CORRECTS THE AIM OF THE HEADLIGHTS IF YOU ARE DRIVING WITH AN UNUSUALLY HEAVY LOAD, SO THAT YOUR LIGHTS DO NOT MOMENTARILY BLIND ONCOMING DRIVERS. UNFORTUNATELY, WHEN THE SENSOR IN THE HEADLIGHT LEVELING SYSTEM FAILS, THE HEADLIGHTS AIM THEMSELVES TO A DEFAULT POSITION THAT IS UNSAFE; THE HEADLIGHTS AIM DOWNWARDS, AND ILLUMINATE THE GROUND 20 FEET IN FRONT OF THE CAR AND NO FARTHER. IT IS NOT SAFE TO DRIVE IN THE DARK FASTER THAN 20 MILES AN HOUR WITH THE HEADLIGHTS LIKE THIS. THE PROBLEM BEGINS WITH THE SENSOR IN THE 2004 AND 2005 MODEL PRIUSES, WHERE A GASKET FAILS AND THE INTERIOR PARTS OF THE SENSOR CORRODE AND FAIL. TOYOTA KNOWS ABOUT THIS PROBLEM AND NOW OFFERS IMPROVED REPLACEMENT PARTS AND HAS ISSUED THE TECHNICAL SERVICE BULLETIN BELOW. HOWEVER, REPLACING THIS PART AT A DEALER CAN COST UPWARDS OF $500, DISCOURAGING MANY OWNERS FROM MAKING THE REPAIR, LEADING TO UNSAFE DRIVING CONDITIONS FOR PRIUS DRIVERS AND EVERYONE ELSE ON THE ROAD. THERE IS NO MANUAL OVERRIDE TO MAKE IT SAFE FOR A DRIVER TO DRIVE IN THE DARK. IT SEEMS LIKE POOR ENGINEERING THAT TOYOTA HAS IMPLEMENTED A SAFETY DEVICE THAT, WHEN IT FAILS, CREATES A MORE UNSAFE CONDITION THAN IF THE SAFETY DEVICE WERE NOT THERE. NOT TO BE OVERLY DRAMATIC, BUT IT WAS A FAILED GASKET AND FAILED SENSORS THAT BROUGHT DOWN THE SPACE SHUTTLE. A REPAIR SUGGESTED ONLINE INVOLVES SPRINGS FROM BALLPOINT PENS, BUT THIS IS RIDICULOUS. A REPAIR WITH THE IMPROVED TOYOTA PART OUGHT TO BE MADE AFFORDABLE, IF NOT FOR FREE. US TSB EL004-06 APRIL 28, 2006.

BOTH HEADLIGHTS WENT OUT DURING NIGHT TIME DRIVING. I IMMEDIATELY BRAKED BECAUSE I COULD NOT SEE ANYTHING IN FRONT OF ME. IT IS A VERY DANGEROUS SITUATION IN THAT MY 9YEAR OLD AND 12 YEAR OLD PANICKED. WHEN I SWITCHED THE LIGHTS ON AND OFF THEY CAME BACK ON. THE INCIDENT RE-OCCURRED AN ADDITIONAL 3 TIMES ON THE WAY HOME. I CONTACTED THE MANUFACTURER AS WELL AS THE DEALER. BOTH SAID THEY COULD NOT DO ANYTHING ABOUT THIS TYPE OF FAILURE SINCE IT IS OUTSIDE THE WARRANTY PERIOD. I COULD UNDERSTAND A LIGHTBULB GOING OUT, BUT BOTH GOING OUT AT THE SAME TIME IS A HORRIFIC DANGEROUS SITUATION. I BELIEVE THERE IS AN INHERENT DEFECT FROM THE MANUFACTURER. *TR

DRIVING ON I-405 WHEN THE LEFT HEADLIGHT BEGAN ACTING INTERMITTENTLY. BROUGHT TO THE ATTENTION OF THE DEALER WHEN STOPPED BY TO INQUIRE ABOUT THE PROBLEM. WAS TOLD THAT THE DEALER WAS UNAWARE WHAT THE PROBLEM COULD BE AND THAT THEIR ONLY SUGGESTION WAS TO REPLACE THE BULB, BUT THAT WOULD COST $500 AND WOULD NOT GUARANTEE FIXING THE PROBLEM. BROUGHT CAR BACK TO DEALER SEVERAL TIMES DURING 2007 AND OVER THE FOLLOWING YEARS TO DISCUSS THIS ISSUE WITH THE HEADLIGHT... YIELDING THE SAME RESULTS FROM THE DEALER. MANY TIMES DURING NIGHT DRIVING THE LEFT HEADLIGHT WOULD GO OUT. FINALLY, IN MARCH, 2013 BOTH HEADLIGHTS WENT OUT WHILE ON I-405 AT NIGHT. HAPPENED TWICE DURING DRIVE HOME WITH 3 SMALL CHILDREN IN THE CAR. HAD HID BULBS REPLACED AS CONSIDERABLE EXPENSE ($657.88) ONLY TO FIND OUT TOYOTA IS COMPLETELY AWARE OF THIS PROBLEM FROM A CLASS ACTION LAWSUIT.

WHILE DRIVING THE PASSENGER HEADLIGHT GOES OUT AT UNEXPECTED TIMES. TRYING TO ACTIVATE THE HIGH HEADLIGHTS DOES NOT MAKE THE LIGHT COME BACK ON.

THE HEADLIGHT ON THE PASSENGER SIDE JUST TURNS OFF FOR NO REASON. I SAW IT OFF WHEN STOPPED. IT HAS DONE IT SEVERAL TIMES AFTER ABOUT A HALF HOUR OF DRIVING. IT GOES BACK ON, BUT I KEEP THE FOG LIGHTS ON JUST IN CASE IT HAPPENS IN THE DARK. I THINK IT COULD EFFECT BOTH HEAD LIGHTS AND CAUSE A SAFETY PROBLEM AT NIGHT. I DRIVE ON UNLIT STREETS AT NIGHT. *TR

HEADLIGHTS WILL RANDOMLY TURN OFF AND ON. SOMETIMES THE LEFT HEADLIGHT WILL GO OUT, SOMETIMES THE RIGHT, AND OCCASIONALLY BOTH LIGHTS WILL GO OUT AT THE SAME TIME. THE HID BULBS ARE NOT TO BLAME. THESE BULBS, WHEN THEY DO GO OUT, THEY BURN OUT AND NEVER COME BACK. THIS ISSUE IS A CONTROL PROBLEM/DESIGN FLAW OF THE VEHICLE. IF THE NHTSA WOULD LOOK IN ITS DATABASE IT WOULD SEE THIS IS NOT AN ISOLATED INCIDENT. IF YOU ARE WAITING ON A BODY COUNT YOU WILL NOT HAVE TO WAIT LONG. MY WIFE WAS DRIVING ON HWY 66 AT 7:30 PM ON MARCH 4TH WHEN A LOOSE COW ENTERED THE ROAD, THEN THE LIGHTS BLINKED OUT. A 2,000 LBS ANIMAL AND A 2,600 LBS CAR DO NOT INTERACT WELL TOGETHER. I SUSPECT YOU WILL KEEP IGNORING THIS AND BE A PATSY FOR TOYOTA. I PLAN ON FILING A SMALL CLAIMS AGAINST TOYOTA AND, IF I CAN FIND A LAWYER WHO WILL TAKE YOU ON, SUE THE NHTSA FOR NOT DOING THEIR JOBS. *TR

THE DRIVER SIDE HEADLIGHT INTERMITTENTLY GOES ON AND OFF WITHOUT WARNING. THIS BEGAN OVER A YEAR AGO, BUT WE CANNOT NAME THE SPECIFIC TIME. WE INITIALLY THOUGHT IT WAS JUST A LIGHT BULB, HOWEVER, WE LEARNED THAT IT CAN BE REACTIVATED BY BRIEFLY TURNING THE HEADLIGHT SWITCH OFF AND ON. THIS IS A SAFETY HAZARD IF DRIVING AT NIGHT. IT CAN HAPPEN SEVERAL TIMES DURING ONE TRIP OR NOT AT ALL. WE HAVE TAKEN IT TO A FEW TOYOTA DEALERS AND THEY HAVE INDICATED THAT IT COULD COST 400-800+ TO REPAIR THE PROBLEM, WHICH WE BELIEVE TO BE EXCESSIVE SO FOR NOW WE ARE TOLERATING THE PROBLEM. *TR

WHILE DRIVING, BOTH HEADLIGHTS WOULD GO OFF. THEY WOULD COME BACK ON WHEN TURNING THE LIGHT CONTROL OFF THEN BACK ON. A FEW MINUTES LATER, THEY WOULD GO OFF AGAIN AND TO GET THEM BACK ON I HAD TO SWITCH OFF/ THEN BACK ON. IT DID NOT SEEM TO BE DEPENDENT ON FAST I WAS DRIVING OR IF A BUMP IN THE ROAD CAUSED THE HEADLIGHTS TO GO OFF. WE TOOK CAR TO DEALER AND WAS TOLD EVERYTHING CHECKED OUT AND BOTH HEADLIGHT BULBS NEEDED TO BE REPLACE @ $175.00 EACH FOR PARTS PLUS LABOR TO DROP FONT BUMPER SO HEADLIGHTS COULD BE INSTALLED. TOTAL BILL CAME TO $485.00 TO REPLACE TWO HEADLIGHTS THAT WORKED INTERMITTENTLY. *TR

I WAS DRIVING ON THIS PARTICULAR DAY AND BOTH HEADLIGHTS JUST SHUT OFF. I WAS DRIVING ON THE HIGHWAY GOING ABOUT 70 MILES AN HOUR. I SLOWED DOWN AS MUCH AS I COULD. ONLY ONE CAR WAS BEHIND ME AND BY CHANCE HE HAD SEEN MY LIGHTS GO OFF AND STARTED TO FLICKER HIS LIGHTS AS HE PASSED ME. LUCKILY THEIR WASN'T ANY CARS ON SITE BECAUSE IT WAS ABOUT 2 AM IN THE MORNING AND THEIR WASN'T ANY TRAFFIC. I WAS ABLE TO PULL OVER UNDER A HIGHWAY STREET LAMP ON THE SHOULDER. I TURNED OFF THE LIGHT AND BACK ON REPEATEDLY UNTIL ABOUT THE 7TH OR 9TH TRY THEY CAME BACK ON. SINCE THEN I HAVE INTERMITTENT LIGHT TURNING OFF ON EITHER HEADLIGHT AT RANDOM TIME. THE DIMMING CAN GO FOR WEEKS WITHOUT SHUTTING OFF AND CAN ALSO GO ON FOR A FULL WEEK WITH THE HEADLIGHTS DAILY. I KNOW THIS IS HAZARD BECAUSE THE TIME WHERE BOTH HEADLIGHTS WENT OUT IT COULD HAVE ENDED IN A DIFFERENT WAY OTHER THEN PULLING OVER SAFELY ON THE SHOULDER. ALSO THE INTERMITTENT LIGHT TURNING OFF OF THE LIGHTS IS ALSO A HAZARD BECAUSE IT DECREASES VISIBILITY BOTH FOR ME TO SEE THE ROAD AND OTHER DRIVERS TO SEE ME. *TR

THE BRAKE LIGHT WENT OUT ON THE DRIVER SIDE. LUCKILY I WAS PULLED OVER BY A POLICE OFFICER WHO WAS COURTEOUS TO LET ME KNOW THE REAR DRIVER-SIDE BRAKE LIGHT WAS OUT. I BELIEVE THIS A HAZARD THAT TOYOTA HAS FAILED TO CORRECT BECAUSE THE LED BRAKE LIGHT BULBS ARE NOT REPAIRABLE/REPLACEABLE, AN SINCE THE LED HAD FAILED AND THE DRIVER-SIDE TAILLIGHT ASSEMBLY IS NOW USELESS AND NON-FUNCTIONAL. I WENT TO THE TOYOTA DEALER AND THEY QUOTED MY 800 DOLLARS TO REPLACE THE TAILLIGHT INCLUDING LABOR. I DON'T LIKE HOW THE LED BRAKE LIGHT IS INTENDED FOR OVER 100,000 HOURS OF LIFE BUT HADN'T LASTED MORE THAN FOUR AND A HALF YEARS OF USE. AND THE WORST PART OF THE SITUATION IS THAT THE LED BULBS ARE NOT REPLACEABLE/REPAIRABLE AND THUS A GREATER DIFFICULTY TO REPAIR AND BRING BACK TO SAFE OPERATING CONDITION. *TR

I HAVE NOTICED THE HEADLAMPS WILL EXTINGUISH INDIVIDUALLY AND UNEXPECTED IN AN INTERMITTENT MANNER, CAUSING A SIGNIFICANT SAFETY HAZARD TO DRIVER AS WELL AS OTHER VEHICLES. I HAVE CONTACTED TOYOTA ABOUT THIS, AND ALTHOUGH THEY HAVE EXTENDED THE WARRANTY WITH THIS OBVIOUSLY FLAWED DESIGN, THEY REFUSE TO TAKE RESPONSIBILITY FOR THE DESIGN AND REPAIR THE SYSTEMS. I HAVE OWNED SEVERAL OTHER VEHICLES WITH HID HEADLAMPS, NEVER HAVE THEY BECOME INTERMITTENT, WHICH IS INDICATIVE OF A DESIGN FLAW OR A SERIOUS MATERIALS PROBLEM WITH THE IGNITER SYSTEM FOR THE HID HEADLAMPS.

THE HID HEADLIGHTS FAIL AND TURN-OFF WITHOUT WARNING. THIS LEADS TO DANGEROUS DRIVING CONDITIONS ESPECIALLY AT NIGHT. THIS IS RELATED TO A HID HEADLIGHT LEVELING SENSOR FAILURE. TOYOTA REPORTS THIS ISSUE IN THEIR "TECHNICAL SERVICE BULLETIN" NUMBER EL004-06, DATED 28TH APRIL 2006. TOYOTA RECOGNIZES THE PROBLEM IN THE OEM PART AND IS PROVIDING REPLACEMENT ONLY ON FAILED PARTS UNDER 36MONTHS, 36,000 MILES WARRANTY. HOWEVER, MY VEHICLE EXPERIENCED THIS "SAFETY ISSUE" PAST THE WARRANTY PERIOD AND HENCE IS NOT REPLACED BY TOYOTA. NEVERTHELESS, TOYOTA HAS GENERATED A CUSTOMER PROGRAM TO REPLACE THIS DEFECTIVE MODULE IN 2006-2009 MODELS EVEN IF NOT UNDER THE WARRANTY. MY 2005 MODEL EXPERIENCES THE EXACT SAME PROBLEM BUT TOYOTA WILL NOT COVER THIS SAFETY ISSUE. FURTHERMORE, THE 2006-2009 MODELS ARE COVERED UNDER THE "CLASS ACTION LAWSUIT" FOR THE EXACT SAME PROBLEM AS MY 2005; HOWEVER MY 2005 MODEL IS NOT COVERED.

IN 2009 WAS THE FIRST TIME THE WARNING LIGHT WAS DISPLAYED REGARDING THE HEADLIGHT LEVELER SENSOR. CONTACTED TOYOTA AND BECAUSE IT WAS OUT OF WARRANTY, THEY WOULD NOT REPAIR UNLESS WE PAID IN FULL FOR REPAIRS. ADVISED THE SENSOR ALONE WAS APPROX. $400, PLUS WHATEVER LABOR IS INVOLVED. HAVE LIVED WITH THE INTERMITTENT WARNING LIGHT COMING ON AND GOING OFF EVER SINCE. IN DECEMBER OF 2011, BEGAN HAVING PROBLEMS WITH THE PASSANGER SIDE HEADLIGHT GOING OFF FOR NO REASON. REPLACED THE BULB AND IT STILL GOES OFF INTERMITTENTLY WHILE DRIVING. IF THE HEADLAMP SWITCH IS TURNED OFF AND BACK ON FROM INSIDE THE CAR, THE HEADLIGHT COMES BACK ON. I SEE THAT THERE WAS A RECALL FOR SIMILAR ISSUES RECENTLY; HOWEVER, IT ONLY COVERED TOYOTA PRIUS VEHICLES YEAR 2006 AND NEWER.

MONTHS LATER, I RECEIVED A WARNING SIGN SAYING THAT THE "HEADLIGHT AUTO LEVEL" MECHANISM WAS BROKEN. AFTER RESEARCHING THIS ISSUE ONLINE AND SPEAKING TO SEVERAL MECHANICS, IT BECAME CLEAR THAT THE PROBLEM WAS CAUSED BY THE PART USED BY TOYOTA. THE PART TOYOTA USES IN ITS OLDER CARS WAS NOT SEALED, MEANING SALT CAN GET IN AND CORRODE THE WIRING.

WHEN I TRIED TO PUT THE HIGH BEAMS ON ALL FRONT END LIGHTS WENT OUT. I MADE IT SAFELY TO MY DESTINATION. THE NEXT DAY I CHECK THE HEADLIGHTS AND THEY BOTH WORKED FINE.

FOUR HOURS INTO MY DRIVE HOME, IT WAS GETTING DARK SO I TURNED MY HEADLIGHTS ON AND THEY WORKED, BUT WITHIN AN HOUR THEY BOTH WENT OFF. I TURNED THEM OFF AND THEN BACK ON AND THEY CAME ON AGAIN.

FOR THE LAST HOUR OF MY DRIVE THE HEADLIGHTS STAYED ON AND WORKED FINE. I'VE HEARD OF OTHER PRIUS OWNERS HAVING SIMILAR PROBLEMS AND I BELIEVE THAT SINCE NON-WORKING HEADLIGHTS ARE A MAJOR SAFETY ISSUE THAT TOYOTA SHOULD RECALL THE PRIUS AND FIX THIS ISSUE. *TR

2005 TOYOTA PRIUS WITH HID HEADLIGHTS WHICH HAS SELF LEVELING FEATURE. HAVE NOTICED FOR A WHILE THE HEADLIGHTS ARE SHINING LOW, CAN'T SEE SUFFICIENTLY AHEAD OF CAR. HEADLIGHTS CAN NOT BE MANUALLY ADJUSTED. FOUND ONLINE SEVERAL REPORTS INDICATING THE CONTROL MODULE THAT SENDS THE LEVELING MESSAGE TO CONTROL THE HEADLIGHTS WHICH IS MOUNTED ON THE DRIVER SIDE REAR AXLE FAILS WHEN WATER ENTERS THE DEVICE AND CORRODES THE UNIT. POOR CONTRUCTION OF THIS UNIT LEAD TO WATER INFILTRATION AND HAS RESULTED IN A DANGEROUS SITUATION DUE TO THE POOR HEADLIGHT PERFORMANCE. TOYOTA HAS BEEN CONTACTED AND THEY HAVE NOT ANSWERED IF A RECALL IS WARRENTED EVEN THOUGH APPARENTLY THE MALFUNCIONING UNIT HAS BEEN REDESIGNED TO STOP WATER INFILTRATION NOR WILL THEY PROVIDE THE NECESSARY REPAIR WITHOUT CHARGING FOR IT. *TT

ON 7/31/11 I NOTICED MY CRUISE CONTROL WOULD NOT SET. THE LIGHT CAME ON INDICATING THE CRUISE WAS ON, BUT I COULD NOT GET THE SPEED TO HOLD. THE NEXT DAY, THE CRUISE CONTROL WORKED. MIDDAY ON 8/1/11 WHILE PARKED, I SHIFTED TO THE D POSITION, BUT THE LIGHT INDICATED I WAS IN N. I SHIFTED BACK AND FORTH BETWEEN R AND D SEVERAL TIMES, BUT THE LIGHT INDICATED N. I TOOK MY FOOT OFF THE BRAKE AND THE CAR MOVED BACKWARD. THE LIGHT INDICATED N AND THE KNOB WAS IN THE D POSITION. IT DID THIS SEVERAL TIMES. I TURNED THE CAR OFF AND BACK ON AND EVERYTHING WORKED LIKE IT IS SUPPOSED TO. ON 8/1/11 AT APPROXIMATELY 10:30 P.M. I WAS DRIVING HOME ON A NARROW, TWO-LANE RURAL HIGHWAY. ON A BLIND CURVE, BOTH OF MY HEADLIGHTS WENT OUT. I COULD NOT SEE ANYTHING. I TRIED CYCLING MY HEADLIGHTS OFF AND ON AND NOTHING HAPPENED. I APPLIED MY BRAKES AND STOPPED. I OPENED MY DOOR TO SEE WHERE I WAS IN THE ROADWAY AND DETERMINED I WAS ON THE FOG LINE ON THE OPPOSITE SIDE OF THE ROAD AND THERE WAS A HILLSIDE LESS THAN 5' FROM ME. I WAS ABLE TO DRIVE TO THE SHOULDER ON THE RIGHT SIDE OF THE ROAD BY USING THE LIGHT FROM MY DOOR. I WAS EXTREMELY LUCKY NO CARS PASSED BY WHILE MY LIGHTS WERE OUT. I COULD HAVE BEEN KILLED OR CAUSED A CATASTROPHE. I TURNED THE CAR OFF AND BACK ON AND BOTH HEADLIGHTS CAME BACK ON. A MOTORIST STOPPED TO ASSIST. I WAS ABLE TO FOLLOW HIM TO A STORE WHERE A FRIEND MET ME AND I FOLLOWED HIM HOME. DURING THE DRIVE HOME ONE OF MY HEADLIGHTS KEPT TURNING OFF. BOTH DID NOT GO OFF TOGETHER AGAIN. I TOOK THE CAR TO THE DEALER ON 8/3/11 AND WAS TOLD I NEED A NEW AUXILIARY BATTERY AND TWO NEW HEADLIGHTS. COST IS GOING TO BE AROUND $700. I READ ABOUT A CLASS ACTION SUIT REGARDING 2006-2009 PRIUS' HEADLIGHTS AND THAT TOYOTA KNOWS THERE IS A PROBLEM WITH THEM.

I HAVE A 2005 TOYOTA PRIUS WITH HID HEADLIGHTS. THEY BEGAN FAILING, FIRST IT WAS ONLY THE DRIVERS SIDE LIGHT, AND INFREQUENTLY. I FOUND THAT WHEN I TURNED THE LIGHTS OFF AND ON AGAIN, THE HEADLIGHT WORKED AGAIN. BECAUSE OF THE HIGH COST OF REPLACEMENT, I LIVED WITH THE PROBLEM. RECENTLY, BOTH LIGHTS FAILED ON A BACK COUNTRY CURVY ROAD. FOR AN INSTANT EVERYTHING WAS TOTALLY BLACK. I QUICKLY TURNED THE LIGHTS OFF AND ON AND WAS ABLE TO SWERVE TO GET BACK ON THE ROAD. AS A RESULT, I AM GOING TO HAVE TO PAY NEARLY $1,000 TO HAVE BOTH HEADLIGHTS REPLACED AT MY EXPENSE, SINCE I HAD MORE THAN 50,000 MILES ON MY PRIUS. TOYOTA CUSTOMER CARE TOLD ME THAT I WOULD NOT BE COVERED BY A CLASS ACTION CASE FOR THE HID BULB REPLACEMENT BECAUSE MY CAR IS A 2005 AND IS NOT COVERED IN THE CASE.

PASSENGER FRONT HID HEADLIGHT WAS INTERMEDIATELY OPERATIONAL FOR A SHORT PERIOD OF TIME. EVENTUALLY IT WOULD NOT COME BACK ON. TOYOTA DEALER QUOTED $350+ FOR PART AND $150+ FOR LABOR, PER HEADLIGHT. ACCORDING TO OTHER PRIUS OWNERS AND INTERNET ARTICLES, THIS ISSUE IS APPARENT TO BE A MANUFACTURER DEFECT; BUT TOYOTA REFUSES TO ADMIT IN ORDER TO PREVENT A RECALL. UNWILLING TO PAID FOR TOYOTA'S MISTAKES, THE VEHICLE WAS DRIVEN WITH ONLY ONE HEADLIGHT FOR SOME TIME. UNTIL RECENTLY STOPPED BY POLICE AND ISSUED A TRAFFIC VIOLATION WARNING. FOR SAFETY REASONS AND TO PREVENT FUTURE VIOLATIONS , REPLACED THE BURNT HID BULB ($50+ FROM AMAZON.COM) PERSONALLY (FOLLOWED PROPER PROCEDURES). A WEEK LATER, THAT SAME BULB WENT OUT.

STARTING IN LATE WINTER, EARLY SPRING OF 2010, WE NOTICED INTERMITTENT OCCASIONAL FAILURE OF ONE OR THE OTHER OF OUR HID HEADLAMPS ON OUR 2005 TOYOTA PRIUS (WHICH WE WERE TOLD BY THE TOYOTA SALESMAN WERE LIFETIME HEADLIGHTS). THIS SITUATION COULD BE IMMEDIATELY RECTIFIED BY QUICKLY TURNING OFF AND ON AGAIN THE HEADLIGHT SWITCH AT THE STEERING WHEEL STALK. THEN, ON JULY 24, 2010, WHILE ON A REMOTE AND STEEP WINDING MOUNTAIN PASS ROAD IN CALIFORNIA, (SONORA PASS ROAD) IN PITCH DARK, BOTH HEADLAMPS FAILED SIMULTANEOUSLY AND COULD NOT BE RECTIFIED WITH A QUICK FLICK OF THE HEADLAMP SWITCH OFF AND ON. I BRAKED HEAVILY, KEEPING IN MY MIND A VISION OF THE CURVE IN THE ROAD I HAD JUST SEEN AHEAD OF ME. BRAKING HEAVILY AND TRYING TO STEER IN THE DARK, I PUT THE FLASHERS ON SO I WOULDN'T BE REAR-ENDED. THIS ENDED UP BEING A FORTUITOUS DECISION, BECAUSE IT WAS SO DARK THAT THE MOMENTARY FLASHES OF THE FORWARD FLASHERS ALLOWED ME TO SEE JUST ENOUGH ROAD IN BRIEF SNIPPETS SO THAT I COULD STEER MY VEHICLE SAFELY AROUND THE CURVE AND GET IT OFF THE ROAD. I FIGURED OUT THAT WITH BOTH LAMPS OUT, A MUCH SLOWER OFF/ON AGAIN CYCLE OF THE HEADLIGHT SWITCH WOULD BRING THEM BACK ON, AND I LIMPED THE VEHICLE HOME. HAVING DRIVEN OVER A MILLION MILES IN MY ADULT LIFE, LUCKILY I HAD THE EXPERIENCE AND THE CALM TO HANDLE THIS SITUATION WITHOUT CATASTROPHIC RESULT. HAD MY WIFE OR MY DAUGHTER BEEN DRIVING, WE CERTAINLY WOULD HAVE GONE OFF THE ROAD AND CRASHED THE VEHICLE. IMMEDIATELY THE FOLLOWING DAY I SCHEDULED AN APPOINTMENT WITH A TOYOTA DEALERSHIP SERVICE CENTER; END RESULT OF WHICH THEY WANT ME TO PAY NEARLY $900 TO REPLACE THESE DEFECTIVE HEADLAMPS. I CALLED TOYOTA, AND UPON INITIAL CONTACT, WON'T DO ANYTHING FOR US. NEEDLESS TO SAY IN THIS ECONOMY, WE DO NOT HAVE THE MONEY, AND WE HAVE BEEN RELEGATED TO DRIVING OUR PRIUS MOSTLY DAYTIMES, AND CERTAINLY NOT ON MOUNTAIN PASS ROADS AT NIGHT. READING ONLINE TOYOTA FORUMS, I AM VERY OBVIOUSLY NOT THE ONLY PERSON WHO HAS THIS PROBLEM. *TR

THE HEADLIGHT LEVEL SWITCH FAILURE (WATER-RUST IN SWITCH) IS CAUSING REAL DANGER. WHEN LOCATED IN UP WHILE IN DIM - ONCOMING TRAFFIC IMPAIRED. WHEN LEVEL SWITCH ENDS DOWN, THE LINE OF SIGHT IS ONLY SEVERAL FEET IN FRONT OF VEHICLE. A SHORTER PERSON (WIFE) IS UNABLE TO SEE ANY LIGHTED ROAD. DRIVING REALLY BECOMES BAD WITH THE BRIGHT SWITCHED ON. ONCOMING TRAFFIC BECOMES IMPAIRED CAUSING DANGER. THE WIFE ACTUALLY REFUSES TO DRIVE AT NIGHT. JUST UNABLE TO SEE PROPERLY. I HAVE TRIED UNSUCCESSFULLY TO CONTACT DIRECTLY TO TOYOTA WITH THIS SITUATION. SERVICE GARAGES WANT JUST UNDER $ 500.00 TO CORRECT PROBLEM. I FEEL THIS SHOULD BE A RECALL ITEM BECAUSE OF QUALITY, BUT MORE IMPORTANTLY THE DRIVING DANGER. THE ACTUAL SWITCH SHOULD BE PURCHASED MUCH LOWER COST. THE VALUE OF SWITCH ALONE WITHOUT THE BRACKETS.WE FEEL THE DANGER ON HIGHWAY TO BE A REAL CONCERN. I HAVE SPOKE WITH OTHER 05 PRIUS OWNERS AND EACH HAS EXPRESS THE PROBLEM. MOST HAVE JUST HAD IT REPAIRED UNDER WARRANTY.

EITHER OR BOTH HIGH-INTENSITY HEADLIGHTS TURN OFF WHILE DRIVING WITHOUT DRIVER INPUT. THIS IS THE EXACT SAME PROBLEM DESCRIBED IN THE CLASS ACTION SETTLEMENT FOR 2006-2009 PRIUS VEHICLES. ACCORDING TO THE LAWSUIT, THE HEADLIGHTS PREMATURELY FAIL BY FLICKERING OR TURNING OFF INTERMITTENTLY, OFTEN REQUIRING COSTLY REPAIRS. ALTHOUGH TOYOTA HAS DENIED THESE CLAIMS, GIRARD GIBBS LLP IS PLEASED TO ANNOUNCE THAT THE PARTIES REACHED A PROPOSED SETTLEMENT THAT HAS BEEN GRANTED PRELIMINARY COURT APPROVAL. AMONG OTHER THINGS, THE SETTLEMENT WILL PROVIDE: ' A FREE WARRANTY EXTENSION FOR HID HEADLIGHT BULB AND ELECTRONIC CONTROL UNITS (THROUGH THE EARLIER OF 5 YEARS AND 50,000 MILES); AND ' CASH REIMBURSEMENTS TO MANY CLASS MEMBERS WHO PAID FOR HEADLIGHT REPAIRS. UNFORTUNATELY, MY VEHICLE YEAR WAS NOT INCLUDED IN THE CLASS. HOWEVER, AS PREVIOUSLY STATED, THE PROBLEM WITH MY VEHICLE IS IDENTICAL TO THOSE IN THE SUIT. THE REPAIR COST ME $593.75. I CONTACTED TOYOTA AND ASKED THEM TO REIMBURSE ME FOR THE REPAIR. THEIR RESPONSE WAS THAT MY VEHICLE IS NO LONGER UNDER WARRANTY AND MY VEHICLE YEAR IS NOT PART OF THE CLASS ACTION SUIT. THEY WILL NOT REIMBURSE ME FOR THE REPAIR. HOWEVER, THE VEHICLES IN THE CLASS ACTION SUIT WERE NO LONGER UNDER WARRANTY. UPDATED 05/04/11

THE PASSENGER SIDE HEADLIGHT WOULD SOMETIMES GO OUT AND THEN COME BACK ON AFTER TURNING THE CAR OFF/ON. EVENTUALLY BOTH OF THE HEADLIGHTS HAD THIS PROBLEM ALONG WITH THEM TURNING PINK IN COLOR AND BACK TO WHITE WHILE DRIVING. I TOOK THE PRIUS INTO THE DEALERSHIP AND SINCE I PURCHASED THE EXTENDED WARRANTY OF 100,000 MILES THE HID ELECTRONIC CONTROL UNITS (ECUS) WILL BE REPLACED FREE OF CHARGE BUT THE HID LIGHT BULBS ARE COSTING $350 TO REPLACE. I SEE THAT TOYOTA HAS EXTENDED THE WARRANTY OF THE LIGHT BULBS TO A FIVE YEAR/50,000 FOR THE 2006-2009 PRIUS STARTING FEB 9TH 2011, TOMORROW. THE MECHANICS SAY THESE BULBS SHOULD LAST OVER A 100,000 MILES BUT THE ECUS ARE MAKING THEM GO BAD EARLY. I HAD A "WONDERFUL" CONVERSATION WITH TOYOTA EXTRA CARE REPRESENTATIVE ABOUT THIS PROBLEM. HE BASICALLY TOLD ME ANYTHING THAT ANYTHING THAT BREAKS THAT IS NOT COVERED BY WARRANTY (HEADLIGHTS) BECAUSE AN ITEM THAT IS UNDER EXTENDED WARRANTY(ECU), IS NOT COVERED. AND THEN HE WENT ON TO EXPLAIN THIS BY TALKING ABOUT WHAT CAME FIRST, CHICKEN OR THE EGG. I WAS HOPING TO GET INTO MORE IN-DEPTH EVOLUTION DISCUSSION WITH HIM, BUT I RAN OUT OF TIME AND PATIENCE.

I HAVE FROM TIME TO TIME THOUGHT THAT MY CAR LIGHTS DID NOT LIGHT UP THE ROAD SO WELL, ESPECIALLY ON THE PASSENGER SIDE. HOWEVER, WHEN I WOULD THINK ABOUT IT BEFORE I WOULD GET INTO THE CAR, I TURNED ON THE HEAD LIGHTS. THEY WORKED AND SEEM TO BE PRETTY BRIGHT. THEY ARE THE NEW TYPE OF LIGHTS. THIS WENT ON FOR A WHILE. HOWEVER, ONE DAY, I DROVE UP TO MY HOUSE AND NOTICED THAT MY PASSENGER-SIDE HEAD LIGHT DID NOT SEEM TO REFLECT ON MY MAILBOX POST AS I THOUGHT IT SHOULD. I HAD TURNED THE LIGHTS OUT. BUT I TURNED THEM BACK ON, GOT OUT OF THE CAR AND THEY WERE ON. THEN ONE DAY, I WAS BEHIND A SUV. I SAW MY CAR'S REFLECTION AND THE PASSENGER LIGHT WAS OUT. I GOT HOME DID NOT TURN OFF THE CAR OR LIGHTS. I GOT OUT OF THE CAR AND CHECK. THE PASSENGER-SIDE HEAD LIGHT WAS OUT. I TURN THE LIGHTS OFF AND THEN BACK ON AND THE LIGHT CAME ON. THE TIME THAT IT TOOK FOR ME TO DISCOVER THIS ACTUALLY TOOK OVER A YEAR. I RECALLED THAT SOMEONE HAD HIT MY CAR ON THAT SIDE (MINOR) BUT THE HEADLAMP ASSEMBLY HAD TO BE REPLACED. SO, I TOOK THE CAR BACK TO THE PLACE IT WAS REPAIRED. THROUGH MY INSURANCE, I HAVE A LIFE-TIME GUARANTEE ON ALL REPAIRS. THEY REPLACED THE HEAD LIGHT. ABOUT 10 DAYS LATER I AM BEHIND A CAR AND I NOTICE THAT MY PASSENGER SIDE HEAD LIGHT IS AGAIN OUT. I CHECKED THE WEB AND HAVE DISCOVERED THAT THIS PROBLEM IS NOT UNIQUE TO MY CAR.

I WAS DRIVING AT NIGHT ON I-75N AND ANOTHER CAR PULLED UP BESIDE ME AND GESTURED THAT SOMETHING WAS WRONG. WE BOTH PULLED OFF THE INTERSTATE AND THEY TOLD ME THAT I HAD NO TAIL LIGHTS AND NO LICENSE PLATE LIGHT. THEY WERE AFRAID THAT SOMEONE WOULD RAM ME SINCE I HAD NO REAR END RUNNING LIGHTS. I ALSO NOTICED THAT MY GLOVE COMPARTMENT LIGHT WAS OUT. I OPENED THE HATCH AND THEN SLAMMED IT AND THE RIGHT TAIL LIGHT AND LICENSE PLATE LIGHTS CAME BACK ON. I PROCEED HOME UNDER FLASHERS IN THE RIGHT HAND LANE OF THE INTERSTATE. THE NEXT DAY I TOOK IT TO THE COBB COUNTY TOYOTA DEALER AND THEY SAID THAT ALL THE BULBS WERE BURNED OUT. I ASKED HOW COULD ALL THOSE LIGHTS GO OUT AT ONCE AND THEY SAID IT HAPPENS. I AUTHORIZED THEM TO REPLACE ALL THE BULBS. THEY LATER CONTACTED ME AND SAID THAT THEY DID NOT HAVE A REPLACEMENT BULB FOR THE GLOVE COMPARTMENT AND I TOLD THEM TO FORGET ABOUT THAT AND WE COULD REPLACE IT LATER.

HAVING HAD THIS HAPPEN AT HIGH SPEEDS ON A BUSY INTERSTATE AT NIGHT WAS MOST UPSETTING AND TO HAVE ALL THESE LIGHTS GO OUT AT ONCE SEEMS SUSPICIOUS, PARTICULARLY WHEN THE GLOVE COMPARTMENT LIGHT WAS DECLARED AS "BURNED OUT" BY DEALER, NOT REPLACED AND NOW WORKS PERFECTLY. *TR

TOYOTA PRIUS HEADLIGHTS- THE REPLACEMENT COST FOR ONE BULB IS RIDICULOUSLY HIGH- ABOUT $199 PLUS LABOR ($110). THE NEW LIGHTBULB OVERHEATS AFTER TWO MINUTES AND TURNS OFF. IF I TURN THE LIGHTS ON AND OFF AGAIN THE BULB WILL COME BACK ON--FOR TWO MINUTES AT A TIME. THIS IS INCREDIBLY DANGEROUS. I HEAR A NEW BULB IS COMING OUT TO REMEDY THE PROBLEM, BUT SINCE MINE WAS "USED" I CANNOT RETURN IT FOR AN EXCHANGE WHEN THE NEW BULBS COME IN. BECAUSE IT IS HALOGEN, THEY WILL ONLY GUARANTEE THE BULB IF THEY INSTALL IT. IT'S A MONOPOLY.

2005 TOYOTA PRIUS: HEADLIGHTS TURN OFF INTERMITTENTLY. HAPPENS EACH TIME VEHICLE IS DRIVEN, EVEN ON VERY SHORT DRIVES. IT IS NECESSARY TO TURN HEADLIGHTS OFF, AND ON TO GET LAMPS TO WORK AGAIN. OCCASIONALLY, BOTH LAMPS GO OUT AT THE SAME TIME. VERY DANGEROUS! I HAVE CHILDREN, AND AM FEARFUL OF DRIVING WITH THEM IN THIS VEHICLE AT NIGHT BECAUSE OF THIS ISSUE. I HAVE TOLD MY TOYOTA DEALERSHIP ABOUT THIS ISSUE, AND WAS TOLD THEY ARE AWARE OF THE ISSUE, AND I SHOULD TURN THEM OFF AND ON TO RESOLVE. THEY ALSO TOLD ME TO REPLACE WOULD BE OVER $400/EACH. ADDITIONALLY, I'M FEARFUL I WILL GET A MOVING VIOLATION WHILE DRIVING AT NIGHT. *TR

THE HEADLIGHTS ON OUR 2005 TOYOTA PRIUS TURN OFF WHILE WE ARE DRIVING. SOMETIMES IT IS THE RIGHT HEADLIGHT, SOMETIMES THE LEFT, AND ONCE IN AWHILE BOTH TURN OFF. IF I TURN OFF THE LIGHTS AND THEN TURN THEM BACK ON THEY BOTH WORK, FOR A WHILE. THE PROBLEM IS INTERMITTENT; THERE IS NO PREDICTING WHEN THE LIGHTS WILL MALFUNCTION. SOMETIMES IT'S WHILE DRIVING AND THEN SOMETIMES WHILE STUCK IN TRAFFIC. *TR

I DRIVE A 2005 TOYOTA PRIUS AND THE HEADLIGHTS HAVE STARTED GOING OFF INTERMITTENTLY WITHOUT WARNING. WHEN I START THE CAR (LIGHT SWITCH IS ALWAYS IN THE ON POSITION), SOMETIMES BOTH LIGHTS ARE ON, SOMETIMES ONE, SOMETIMES NONE. WHILE DRIVING THE CAR, THE LIGHTS WILL SUDDENLY GO OUT, USUALLY ONE OR THE OTHER, BUT THERE HAVE BEEN TIMES WHERE BOTH WENT OUT. I HAVE RESEARCHED THE PROBLEM AND THERE DOESN'T APPEAR TO BE A KNOWN SOLUTION. I PLAN TO PURCHASE A REPLACEMENT BULB TO SEE IF THAT SOLVES THE PROBLEM. *TR

AT ABOUT 104K MILES THE HID HEADLIGHTS, ALONG WITH THE DASH DASHBOARD LIGHTS, WENT OUT WHILE MY DAUGHTER WAS DRIVING ON A COUNTRY ROAD AT NIGHT. THE SUDDEN DARKNESS RESULTED IN A COLLISION WITH A GUARD RAIL WHILE BRAKING. AFTER PUTTING THE CAR IN PARK, TURNING OFF THE POWER BUTTON AND RESTARTING THE CAR EVERYTHING CAME BACK ON. WHILE WE WERE SHAKEN UP, NO ONE WAS HURT. THE CAR SUSTAINED $2K DAMAGE TO THE BODY, BUT NOT TO THE HEADLIGHTS. THE LOCAL DEALER DIDN'T EXPRESS ANY KNOWLEDGE OF HEADLIGHT FAILURES IN PRIUSES, INSPECTED THE LIGHTING SYSTEM AND PRONOUNCED EVERYTHING FINE. I DID HAVE TO PAY FOR THE INSPECTION AS THE LIGHTS WEREN'T DAMAGED AND NOT COVERED BY THE COLLISION CLAIM. INTERNET RESEARCH HAS BROUGHT UP MANY SIMILAR CASES OF THIS OCCURRING WITH OTHER PRIUSES; WITH NO ACKNOWLEDGEMENT BY TOYOTA. MY DAUGHTER IS NOW TERRIFIED OF DRIVING THIS CAR. I ALSO OWN A 2007 PRIUS WITH HID LIGHTS AND 55K MILES. I'M MONITORING IT'S HEADLIGHTS WHENEVER POSSIBLE AS IT IS DRIVEN MOSTLY DURING THE DAY WITH THE HEADLIGHTS ON. *TR

OVER THE PAST TWO MONTHS, MY 2005 PRIUS HAS DEVELOPED AN INTERMITTENT HEADLIGHT FAILURE. THE HEADLIGHT IN QUESTION IS ON THE PASSENGER SIDE OF THE VEHICLE. TURNING OFF THE HEADLIGHTS AND TURNING THEM BACK ON RESOLVES THE ISSUE, THUS THE BULB IS NOT THE ISSUE. THIS DEFECT MAKES THE VEHICLE LESS SAFE TO OPERATE AND HOLDS ME CIVILLY RESPONSIBLE FOR "FIX IT" DAMAGES. THE "FIX" FOR THIS DEFECT IS A REPLACEMENT SHOULD NOT BE MY RESPONSIBILITY FOR IT IS NOT A FAILURE OF OBSOLESCENCE.

HID HEADLAMP FAILURE ON MY 2005 TOYOTA PRIUS. IT WOULD WORK SOMETIMES AND THEN GO OFF AS I WAS DRIVING DOWN THE ROAD. TOOK TO DEALER 3/26/10; THEY REPLACED THE HEADLIGHT BULB FOR $198.09. IT WORKED FOR ABOUT A MONTH THEN STARTED FLICKERING OFF AGAIN AS I DROVE DOWN THE ROAD. I COULD TURN IT OFF COMPLETELY THEN BACK ON AND IT WOULD WORK FOR ONLY A FEW SECONDS. TOOK TO DEALER AGAIN TODAY 6/21/10 AND THEY SAID IT NEEDS A NEW ASSEMBLY BECAUSE IT HAD BEEN "HIT". MY HUSBAND BACKED INTO AND SCRAPED THE HEADLIGHT COVER IN 2006 (FIVE YEARS AGO), BUT IT WORKED PERFECTLY UNTIL FEB. 2010.

THE HEADLIGHTS ON MY 2005 TOYOTA PRIUS GO OUT INTERMITTENTLY WITHOUT WARNING, ONE AT A TIME. THE BULBS WILL COME BACK ON AFTER THE FIRST OR SECOND TIME OF RESTARTING THE CAR. THIS MAY BE HAPPENING MORE OFTEN THAN I'M AWARE. THE FIRST TIME WAS ABOUT 7 MONTHS AGO WHEN A CHP OFFICER PULLED ME OVER AND GAVE ME A FIXIT TICKET FOR THE HEADLIGHT BEING OUT. IT WAS TOO LATE AT NIGHT TO BUY ANOTHER BULB ANYWHERE. I PULLED INTO A LIGHTED PARKING LOT TO SEE IF THERE MIGHT BE A LOOSE CONNECTION. I TURNED OFF THE CAR, OPENED THE HOOD, REMOVED SOME PARTS THAT WERE IN THE WAY OF ACCESSING THE BACK OF THE PASSENGER SIDE HEADLIGHT, AND JIGGLED THE CONNECTION TO THE BULB. I TURNED THE CAR BACK ON AND THE LIGHT WORKED. THE NEXT TIME I WAS AT A SERVICE APPOINTMENT AT THE DEALER I ASKED THEM IF THEY WERE AWARE OF ANY PROBLEMS WITH THE HEADLIGHTS GOING OUT INTERMITTENTLY. THE SERVICE REP SAID THEY DO THAT OCCASIONALLY, BUT SINCE THEY WERE EXPENSIVE TO REPAIR, TO JUST KEEP DRIVING UNTIL IT GOES OUT ALTOGETHER. ABOUT 3 OR 4 MONTHS AGO, MY DRIVER SIDE HEADLIGHT DID THE SAME THING THAT TIME, I WASN'T ABLE TO REMOVE THE BACK OF THE HEADLIGHT. I WAS IN A REMOTE LOCATION LATE AT NIGHT ABOUT 50 MILES ALONG A WINDING 2-LANE ROAD AWAY FROM MY DESTINATION. I STARTED THE CAR BACK UP AND THE DRIVER SIDE HEADLIGHT WAS STILL OUT. I DECIDED TO CONTINUE ON TO MY DESTINATION WITH JUST ONE HEADLIGHT, TAKING A CHANCE THE OTHER WOULDN'T GO OUT. THE NEXT DAY WHEN I STARTED THE CAR, BOTH HEADLIGHTS WERE WORKING FINE. LAST NIGHT, THE PASSENGER SIDE HEADLIGHT WENT OUT FOR THE SECOND TIME (THAT I'M AWARE). I WAS ON A 3-HOUR DRIVE HOME AFTER WORKING OUT OF TOWN ALL WEEK. I STOPPED FOR SOME COFFEE AND WHEN I TURNED THE CAR BACK ON, BOTH HEADLIGHTS WERE WORKING FINE. AFTER ABOUT 10 MINUTES DRIVING, THOUGH, THE PASSENGER SIDE HEADLIGHT WENT OUT AGAIN AND STAYED OUT ALL THE REST OF THE TRIP HOME. TODAY I GOOGLED THE PROBLEM; SEVERAL OTHERS HAVE HAD SIMILAR PROBLEMS WITH PRIUS HEADLIGHTS. *TR

THE HID HEADLIGHTS ON MY 2005 TOYOTA PRIUS WENT OUT SEVERAL NIGHTS AGO. THE CAR WAS TAKEN TO TOYOTA, AND THIS PROBLEM IS COMMON ON THE 2004-2008 PRIUS, WHICH A SIMPLE GOOGLE SEARCH PROVED. THESE TYPE OF BULBS OVERHEAT (SINCE THEY'RE HALOGEN). NEVERTHELESS, THEY CHARGED $1150 FOR TWO HEADLIGHTS WHICH CANNOT BE BOUGHT ANYWHERE EXCEPT THE TOYOTA DEALERSHIP. THEY WERE ONLY 2 YEARS OLD. WHEN I CALLED TOYOTA, THE PERSON I TALKED TO UNDERSTOOD, SAYING IT HAD HAPPENED TO HIM TOO, BUT THERE WAS NOTHING HE COULD DO SINCE THE CAR HAD OVER 136,000 MILES ON IT. APPARENTLY TOYOTA ONLY WARRANTIES ITS PARTS FOR ONE YEAR. SHAMEFUL. *TR

I HAD BEEN PULLED OVER ON SEVERAL OCCASSIONS FOR FAULTY TAIL LIGHTS. THIS HAS BEEN ONGOING SINCE I BOUGHT THE CAR. THEN MY CHILDREN TOLD ME OF THE FRONT HEAD LIGHTS GOING OUT FOR NO REASON. I DID NOT BELIEVE THEM TILL THE WENT OUT ON ME. AFTER TAKING IT TO SEVERAL TOYOTA DEALERS AND SAID THAT THERE IS NOTHING WRONG, ON 09/10/2009 I FILED A COMPLAINT WITH A "MONICA" FROM THE NHTSA IN DC. I HAVE YET TO HEAR ANYTHING TO THIS DATE AND I AM AFRAID OF A SERIOUS CRASH WHEN THE LIGHTS GO OUT WITHOUT KNOWING WHY. I ALSO HAVE A CHECK LIGHT THAT HAS BEEN ON SINCE BEFORE MY WARRANTY WENT OUT AND NO ONE WANTS TO CORRECT THE PROBLEM. I HATE THIS CAR, IT SCARES ME AND THERE ARE OTHER ISSUES AND I HAVE TO DATE ONLY RECEIVED ONE RECALL AND THAT IS ON THE MATS. *TR

WHILE DRIVING MY CAR, A 2005 TOYOTA PRIUS, THE HEADLIGHTS WILL JUST STOP WORKING. IT BEGAN WITH THE RIGHT HEADLIGHT, SOMETIMES IT IS BOTH HEADLIGHTS. THE HEADLIGHTS WILL SOMETIMES COME BACK ON IF THEY ARE TURNED OFF AND THEN BACK ON, SOMETIMES THE CAR MUST BE TURNED OFF AND THEN ON AGAIN. THE DEALER HAS SAID THAT IT COULD BE FIXED BY REPLACING THE ENTIRE HEADLIGHT UNIT (NOT JUST THE BULB) AT OVER $300 EACH OR POSSIBLY THE COMPUTER CONTROL BOARD AT OVER $1000.

I WAS DRIVING AT NIGHT AND SUDDENLY REALIZED I COULDN'T SEE THE ROAD IN FRONT OF ME. WHEN I PULLED UP TO A STOP LIGHT, I COULD SEE THE REFLECTION OF BOTH HEADLIGHTS ON IN THE BACK OF THE CAR IN FRONT OF ME, BUT WHEN I STARTED DRIVING AGAIN I COULDN'T SEE THE ROAD AGAIN. I PUT MY HIGH BEAMS ON AND THEY WORKED, BUT THE REGULAR LIGHTS HAD BECOME TOO DIM TO SEE ANYTHING. I JUST REPLACED ONE OF THE BULBS TWO MONTHS AGO BECAUSE IT WAS OUT, BUT NOW THEY ARE BOTH WORKING BUT TOO DIM TO BE USEFUL. THE TOYOTA DEALER SAID THE BULBS NEED TO BE REPLACED, BUT ONE OF THEM IS BARELY TWO MONTHS OLD. I ASKED A NON-TOYOTA DEALER AND THEY SAID IT IS NOT A BULB PROBLEM IF THE BULBS WORK, BUT A WIRING OR BATTERY PROBLEM. I DON'T KNOW WHAT TO DO BECAUSE I DON'T WANT TO PAY TO FIX THE WRONG PROBLEM, SINCE I JUST REPLACED A HEADLAMP THAT CAN'T BE THE ISSUE. *TR

THEY COULD HAVE BEEN AN ACCIDENT. CHECKED WITH OTHER PRIUS OWNERS. FOUND OUT, IT'S A WIDESPREAD ISSUE WITH THE PRIUS. TOYOTA IS AWARE OF THE PROBLEM AND NEEDS TO ADDRESS IT BEFORE SOMEONE GETS SERIOUSLY HURT OR KILLED. OVERALL THE CAR IS FINE BUT THIS HEADLAMP ISSUE NEEDS TO BE ADDRESSED FROM A SAFETY PERSPECTIVE. THERE ARE NO DEATHS /INJURY IN MY CASE BUT PREVENTION IS THE KEY. THANK YOU. *TR

AFTER A FEW MINUTES (3 ' 7) THE LEFT HEADLAMP GOES COMPLETELY OUT. TURNING THE LIGHTS OFF AND THEN ON AGAIN STARTS THE CYCLE ALL OVER AGAIN. I HAVE BEEN PULLED OVER BECAUSE THE LIGHT WAS OUT.

I'M CONSTANTLY REPLACING THE HEADLIGHTS IN MY 2005 TOYOTA PRIUS (NON-HID BULBS) AS THEY HAVE STOPPED WORKING 6 TIMES IN THE LAST 35K MILES. I'VE REPLACED THEM WITH DIFFERENT MANUFACTURER'S BULBS, DIFFERING MODELS, AND EVEN OEM BULBS, BUT THEY KEEP GOING OUT. THE FIRST TIME THEY ACTUALLY WENT OUT WITH BOTH HEADLIGHTS TOGETHER AT EXACTLY 100,000 MILES. I DON'T KNOW IF THIS IS PLANNED OBSOLENCE OR SOMETHING ELSE, BUT BOTH HEADLIGHTS GOING OUT WHILE DRIVING AT NIGHT IS FAR FROM SAFE. GIVEN THE FACT THAT THE DEALERSHIP WANTS ALMOST $300 PER BULB CHANGE, THIS IS GETTING PRETTY RIDICULOUS, AND I'M NOT THRILLED ABOUT THE CONCEPT OF GETTING TICKETS DUE TO BULBS BURNING OUT EVERY COUPLE OF WEEKS. ASIDE FROM THE INCONVENIENCE AND COST, I'M REALLY CONCERNED ABOUT THE SAFETY ASPECTS OF THIS RECURRING PROBLEM. *TR

I HAVE A 2005 TOYOTA PRIUS WITH DEFECTIVE HID HEADLIGHTS. THESE LIGHTS ARE VERY EXPENSIVE TO REPLACE ($650+/-EACH) AND BURN OUT ABOUT EVERY YEAR. MY HEADLIGHTS HAVE GONE OUT ON SEVERAL OCCASIONS, INCLUDING ON THE FREEWAY AT 8:30PM IN THE DARK. EVERYONE I KNOW WHO OWNS A PRIUS HAS HAD THE SAME PROBLEM. TOYOTA FREELY ADMITS THE HEADLIGHTS ARE DEFECTIVE, AND BECAUSE OF THAT THEY ARE NOT EVEN AN OPTION ON THE 2010 PRIUS, BUT DENIES THAT THE BAD HEADLIGHTS ARE A SAFETY CONCERN. I DISAGREE. HAVING MY HEADLIGHTS SUDDENLY TURN OFF AT 65MPH ON A DARK FREEWAY IS CERTAINLY A SAFETY CONCERN. *TR

1 - MY RIGHT HEADLIGHT KEEPS GOING ON AND OFF WHILE I AM DRIVING. I RECEIVED A TICKET THAT I NOW HAVE TO PAY FOR. THE LOS ANGELES TIMES MENTIONED THAT OTHER CARS HAVE THIS PROBLEM.

I HAD ASKED WHEN THE CAR WAS SERVICED AND WAS TOLD THERE WAS NOTHING WRONG.

I HAVE HAD FOUR INSTANCES WHERE BOTH HEADLIGHTS HAVE GONE OUT COMPLETELY LEAVING ME IN A SERIOUS SITUATION SINCE I LIVE IN A RURAL AREA WITH NO STREET LIGHTING AND CURVEY ROADS. I HAVE READ ONLINE OF THE THOUSANDS OF PEOPLE BLOGGING AND COMPLAINING OF THEIR SAME PROBLEMS. I WAS TOLD BY LANCASTER, CA. DEALERSHIP IT NEEDS HEADLAMPS REPLACED. ONLINE PEOPLE ALL STATE THEY HAVED HAD THEM REPLACED AND THE PROBLEM STILL EXISTS. MINE GOES OUT SOMETIMES MINUTES AFTER TURNING ON THE CAR. OTHER TIMES IT GOES FOR ABOUT 20 MINUTES BEFORE SHUTTING OFF. IT IS RANDOM AND SEEMS TO HAVE NO PATTERN. I DO NOT BELIEVE IT IS ONLY THE HEADLAMPS BECAUSE OF WHAT THE NUMEROUS PEOPLE ONLINE HAVE SAID IS THE RESULT AFTER THEIR HEADLIGHTS BEING CHANGED. IT STILL GOES OUT ON THEM, JUST EVERY 30 MINUTES NOT EVERY 20 SECONDS THEY WRITE. THIS IS NOT ACCEPTABLE. I HAVE ALSO TRIED LIKE THE ONLINE PEOPLE SUGGEST BY TURNING ON THE SWITCH BACK AND FORTH.

THE MANUFACTURER WILL ONLY COVER THE COST OF THE PARTS NOT THE LABOR. THE CURRENT MILEAGE WAS 45,000. THE FAILURE MILEAGE WAS 40,000.

I HAVE A 2005 TOYOTA PRIUS. THE HEADLIGHTS WILL GO OUT, SOMETIMES BOTH, SOMETIMES ONE OR THE OTHER. HOWEVER, THEY COME BACK ON WHEN I TURN THEM COMPLETELY OFF AND BACK ON. THIS IS A SAFETY CONCERN FOR OBVIOUS REASONS, AND CAN CAUSE MY VEHICLE TO NOT PASS INSPECTION. THERE IS NO SPECIFIC EVENT THAT MAKES THE HEADLIGHTS GO OFF. IT HAPPENS INTERMITTENTLY AND UNEXPECTEDLY. ADDING TO THE SAFETY ISSUE...I LIVE IN THE COUNTRY WHERE THERE OFTEN ARE NO SHOULDERS ON THE HIGHWAYS OR COUNTY ROADS, AND NO STREET LIGHTS. THERE ARE LOTS OF STEEP DITCHES AND CREEKS. WHEN I FIRST STARTED HAVING THE PROBLEM AND WOULD COMPLETELY TURN OFF THE LIGHTS AND THEN TURN THEM BACK ON, THEY WOULD STAY ON FOR A LONG TIME, SOMETIMES SEVERAL HOURS BEFORE GOING OFF AGAIN. NOW, THEY STAY ON ONLY A FEW SECONDS TO A FEW MINUTES. I'VE GOT TWO THEORIES, ONE IS THAT IT COULD BE A SHORT??? -AND THE OTHER THAT THE COOLER TEMPERATURES SEEM TO AFFECT IT SLIGHTLY, THOUGH NEITHER OF THESE SEEM TO MAKE LOGICAL SENSE. PLEASE CHECK INTO THIS AS OTHER PRIUS OWNERS HAVE HAD THE SAME UNRESOLVED PROBLEM. WE CAN'T ALL JUST GO REPLACING THE COMPUTERS AND LIGHT BULBS AT THE HIGH COST YOU SELL THEM FOR, ESPECIALLY WHEN IT DOESN'T FIX THE PROBLEM...UNLESS TOYOTA WANTS TO PAY FOR IT, OF COURSE, AND THEN THAT'S TIME WITHOUT TRANSPORTATION. THANKS FOR YOUR CONSIDERATION ON THIS MATTER. *TR

2005 PRIUS WITH THE SAME HEADLIGHT ISSUES AS STATED IN PE09019. I UNDERSTAND THIS INVESTIGATION HAS BEEN CLOSED, BUT I WANTED TO REGISTER ANOTHER PRIUS USER WITH A SIMILAR ISSUE. *TR

WHILE DRIVING OUR 2005 TOYOTA PRIUS, MY WIFE WAS TRAVELING AT 65MPH, AT NIGHT WHEN THE RIGHT HEADLIGHT WENT OUT. A MOMENT LATER, ALL FORWARD LIGHTING FAILED. SHE CYCLED THE HEADLIGHT "ON-OFF" SWITCH AND THE GOOD LEFT HEADLIGHT RELIT. A FEW MINUTES LATER ALL WENT DARK AGAIN. SHE TURNED THE HEADLIGHT "ON-OFF " SWITCH OFF THEN ON, AND THE LEFT HEADLIGHT RELIT. THIS REPEATED SEVERAL TIMES UNTIL SHE GOT HOME. ON MONDAY, 10-2-09 WE TOOK THE CAR TO SAN LUIS OBISPO TOYOTA FOR REPAIR. THEY HAD IT TILL 10-5-09,REPLACING THE RIGHT HEADLIGHT, AT A COST OF $528.82. ON 10-20-09 WHILE I WAS DRIVING ON US101 AT 65 MPH IN THE DARK, THE LEFT HEADLIGHT WENT OUT. A MOMENT LATER ALL FORWARD LIGHTS WENT OUT. DUE TO MY WIFE'S PREVIOUS EXPERIENCE, I CYCLED THE HEADLIGHT "ON-OFF" SWITCH AND GOT THE RIGHT HEADLIGHT TO RELIGHT. THIS SUDDEN LOSS OF LIGHTING RECURRED 2 MORE TIMES PRIOR TO THE SUN RISING ENOUGH SO THAT I DID NOT NEED THE HEADLIGHTS. ON 10-28-09, AFTER RETURNING FROM A TRIP, I HAD THE LEFT HEADLIGHT REPLACED AT MILLER TOYOTA IN ANAHEIM AT A COST OF $362.31. ON BOTH OCCASIONS OF THE LIGHTING FAILURE THE VEHICLE WAS TRAVELING AT 65MPH, OR APPROX. 100 FEET PER SECOND. IT TOOK APPROX. 5 TO 10 SECONDS TO RECOGNIZE THE DEFECT AND MAKE A CORRECTION THAT RELIT THE LIGHTS. THE VEHICLE TRAVELED FROM 500 FEET TO 1000 FEET PER INCIDENT. FORTUNATELY THERE WAS NO COLLISION. AT NEITHER TOYOTA DEALER, WERE WE ADVISED THAT THIS WAS A RECURRING PROBLEM ON PRIUS'S, WHICH I FOUND OUT ON-LINE. *TR

THE LEFT HEADLIGHT ON MY 2005 PRIUS DOESN'T STAY LIT, BUT IT WILL COME BACK ON IF LIGHTS ARE TURNED OFF AND THEN BACK ON. THE LIGHT WILL GOT OUT INTERMITTENTLY, STAYING ON FOR ABOUT 5 MINUTES AND THEN GOING OUT AGAIN. THIS IS A SAFETY CONCERN. I HAVE READ OTHER SIMILAR COMPLAINTS, INCLUDING ON THIS WEBSITE. I CONSIDER THIS TO BE VERY DANGEROUS. *TR

Mileage: 79,000

LEFT HEADLAMP WILL NOT STAY LIT. TURNING LIGHTS OFF AND BACK ON AGAIN RE-LIGHTS IT. REPLACING BULB HAS NOT HELPED. FOUND ON THE INTERNET THAT OTHERS ARE HAVING THE SAME PROBLEM. FEEL THAT TOYOTA SHOULD RECALL THE VEHICLES TO FIX THE PROBLEM. *TR

MY HEADLIGHTS WENT OUT ON MY 2005 PRIUS WHILE DRIVING DOWN THE FREEWAY AT NIGHT IN A STORM... THE ONLY MEANS I HAD TO FIND MY WAY TO THE SIDE OF THE ROAD WAS LISTENING TO THE SOUND OF THE BUMPS ON THE SIDE. I PULLED OVER AND SAT IN THE DARKNESS WONDERING IF A CAR WOULD COME AROUND THE CORNER AND HIT ME. I TURNED OFF MY CAR AND RESTARTED IT. THE LIGHTS CAME ON AGAIN AND I WAS ABLE TO GET TO SAFELY. I WENT INTO THE LOCAL DEALERSHIP AND JUST FOUND OUT THAT THE LIGHTS NEEDED TO BE REPLACED AT ABOUT $1,000.00. THAT IS RIDICULOUS. THIS IS A DANGEROUS PROBLEM. I HAVE HAD FULL CARE ON MY VEHICLE AS RECOMMENDED BY THE TOYOTA COMPANY THROUGH MY LOCAL DEALERSHIP. I FEEL THAT THIS PROBLEM IS POTENTIALLY LIFE THREATENING!!!!!!!!!!!!!!!!!!! MY HEART STILL RACES EVERYTIME I THINK ABOUT HOW THAT FELT TO BE IN THE DARK WITHOUT KNOWING WHERE I WAS ON THE ROAD!!!!! PLEASE DO SOMETHING TO HELP THE NEXT VICTIM, WHO MAY NOT BE SO LUCKY. *TR

THE HID HEADLIGHTS ON MY 2005 TOYOTA PRIUS STARTED BLINKING ON AND OFF AND THEN FAILED. ONLY ONE LIGHT WENT OUT BUT I WAS AFRAID BOTH WOULD GO. TOYOTA WANTS $380 FOR THE BULB, WHICH IS ONLY $80 FROM SYLVANIA AND THEY WANT $125 FOR LABOR. TO REPLACE. I FOUND OUT ONLINE THAT THE BULBS KEEP GOING OUT OR BLINKING SO I DON'T WANT TO SPEND THAT MUCH MONEY OVER AND OVER. BULBS ARE A SAFETY ISSUE AND IF THEY ARE DEFECTIVE OR THE SYSTEM IS DEFECTIVE THEY SHOULD BE RECALLED. *TR

I OWN A 2005 TOYOTA PRIUS, AND THE HEADLIGHTS HAVE BOTH GONE OUT. THEY ARE SUPPOSED TO LAST 10 YEARS. FOR A WHILE, WHEN I TURNED OFF THE HEADLIGHTS AND TURNED THEM BACK ON, THEY WOULD WORK. HOWEVER, THEY DO GO OUT WHEN I AM ON THE ROAD QUITE OFTEN. I HAVE BEEN QUOTED BY THE DEALERSHIP THAT REPLACING A SINGLE LIGHTBULB WILL COST OVER $400 INCLUDING PARTS AND LABOR. THIS IS A SAFETY ISSUE BECAUSE I DRIVE TO WORK IN THE EARLY IN THE MORNING AND LATE AT NIGHT, AND MY HEADLIGHTS DO NOT FUNCTION RELIABLY. I HAVE HEARD THIS COMPLAINT FROM OTHER PRIUS OWNERS, WHO ARE OTHERWISE HAPPY WITH THEIR VEHICLES. FOR A LIGHTBULB THAT IS SUPPOSED TO LAST 10 YEARS, THIS IS DEFINITELY A FAULTY AND DANGEROUS PART ISSUE. *TR

HEADLIGHT ON 2005 PRIUS INTERMITTENTLY FAILS. SPORADIC, BUT SOMETIMES RECURS EVERY FEW MINUTES. TURNING THE LIGHTS OFF AND ON QUICKLY CORRECTS PROBLEM ESSENTIALLY 100% OF THE TIME. ESTIMATE TO REPLACE BULB EXCEEDED $400, AND NO GUARANTEE THE PROBLEM WOULD BE CORRECTED. ONLINE SEARCHES SHOWS THIS IS NOT AN ISOLATED PROBLEM. OTHERS DESCRIBE BOTH LIGHTS GOING OUT SIMULTANEOUSLY, AN OBVIOUS HAZARD. *TR

HID HEADLIGHTS FAIL INTERMITTENTLY. THEY EITHER FAIL TO LIGHT UP OR GO OUT WHILE DRIVING. SOMETIMES THEY OPERATE NORMALLY, OTHER TIMES THEY FAIL. NO PATTERN TO IT -- IT SEEMS RANDOM.

I HAVE A 2005 PRIUS I PURCHASED IN 10-2004. MY PROBLEM IS THE SAME AS THE 338 PLUS PREVIOUSLY REPORTED PROBLEMS WITH THE HID HEADLIGHTS GOING OUT. THE PASSENGER LIGHT STARTED GOING OUT AT AROUND 50,000 MILES. IT WAS AT THE TIME EASILY CORRECTED BY TURNING THE HEADLIGHTS OFF AND ON AGAIN. WHEN DRIVING IN TOWN IT IS SOMETIMES HARD TO TELL IF THE HEADLIGHT HAS GONE OUT WITHOUT LEANING FORWARD OR WATCHING FOR THE HEADLIGHTS REFLECTING OFF A CAR IN FRONT OF ME. THIS HAS BEEN MOSTLY ANNOYING UNTIL THE DRIVER'S SIDE HEADLIGHT STARTED DOING THE SAME THING. NOW IT IS DANGEROUS. I DO NOT FEEL SAFE DRIVING MY CAR AT NIGHT BECAUSE AT ANY TIME NOT KNOWING THE RIGHT LIGHT IS OUT THE DRIVER SIDE LIGHT WILL GO OUT AND I AM DRIVING WITH NO HEADLIGHTS. THE FIRST TIME THIS OCCURRED WAS RETURNING FROM A LONG TRIP, DRIVING 65 MPH, 12:30 AM. ALL OF A SUDDEN I HAD NO HEADLIGHTS. LUCKILY THIS HAD NOT OCCURRED 40 MILES EARLIER IN MY TRAVELS. I WOULD HAVE BEEN DRIVING ON INTERSTATE, 65 MPH THROUGH TWO WAY ROAD CONSTRUCTION, PERHAPS AROUND A CURVE. I HAD THREE TEENAGE PASSENGERS WITH ME. IT COULD HAVE BEEN DISASTROUS. AT TIMES IT NOW TAKES TWO OR THREE ATTEMPTS TO GET THE HEADLIGHTS BACK ON. THE COST TO REPAIR, PER MY LOCAL TOYOTA DEALER IS $300.00 EACH FOR THE PART THAT CONTROLS THE HEADLIGHT. THIS DOES NOT INCLUDE REPLACEMENT COST. *TR

HEADLIGHTS ON 2005 PRIUS GO OUT. I HAVE REPLACED THEM TWICE AND THEY INTERMITTENTLY GO OUT STILL. TOO MUCH MOISTURE IN THE AIR THEY GO OUT. SOMETIMES THEY WILL COME BACK ON IF I TURN THEM ON AND OFF. THE DRIVERS SIDE HEADLIGHT GOES OUT AND STAYS OUT FOR WEEKS. *TR

TOYOTA PRIUS HID HEADLIGHTS BLINK OFF AND ON. SOMETIMES STAY OFF UNTIL SWITCHED OFF, AND BACK ON. REPAIR COST INCLUDING LABOR, BULB AND NEW HID DRIVER "CHIP" EXCESSIVE AT $1,200 PER SIDE. DRIVING WITH UNRELIABLE HEADLIGHTS IS DANGEROUS. *TR

LIKE SO MANY OTHER COMPLAINTS I'VE READ TODAY, I AM EXPERIENCING PROBLEMS WITH ONE OF THE HEADLIGHTS TURNING OFF INTERMITTENTLY, WITHOUT REASON (IT HAPPENS WHEN JUST SITTING IDLE). WHEN THE LIGHT GOES OFF, I FLIP THE HEADLIGHT SWITCH OFF AND ON, AND IT COMES BACK ON. IT WILL THEN REMAIN ON FOR A WHILE (COULD BE 30 MINUTES, OR IT COULD BE 2 MINUTES). I WAS TOLD THAT THIS IS UNLIKELY TO BE THE HID BULB OR BALLAST. I HAVE READ MANY COMPLAINTS ON DIFFERENT FORUMS. THIS IS A SERIOUS SAFETY CONCERN, AND TOYOTA SHOULD FIND THE CAUSE, AND RECALL FOR REPAIRS. *TR

ON MY 2005 TOYOTA PRIUS, THE PASSENGER SIDE HEADLIGHT STARTED TURNING PINK WHEN I TURNED ON THE LIGHTS. NOW IT DOESN'T TURN PINK ANYMORE BUT IS QUITE DIM -- ABOUT 30 PERCENT OF THE BRIGHTNESS OF THE OTHER HEADLIGHT. MY TOYOTA DEALERSHIP SAID TO BRING IT IN FOR REPAIR BUT IT WOULD COST AT LEAST $400-$500. *TR

TL*-THE CONTACT OWNS A 2005 TOYOTA PRUIS. THE CONTACT STATED THAT THE TAIL AND HEADLIGHTS INTERMITTENTLY FAIL. A REDUCTION OF VISIBILITY DUE TO HEAD-LAMP FAILURE INCREASES THE RISK OF VEHICLE CRASH. THE VEHICLE WAS TAKEN TO THE DEALER, BUT THE TECHNICIANS WERE UNABLE TO IDENTIFY THE CAUSE OF THE FAILURE. THE MANUFACTURER WAS NOTIFIED. THE FAILURE AND CURRENT MILEAGES WERE 189,000.

WHILE DRIVING OUR VEHICLE (2005 TOYOTA PRIUS) THE DRIVER'S SIDE HEADLIGHT JUST GOES OFF WITHOUT NOTICE. UNABLE TO REPAIR DUE TO IT COSTING APPROX $800.00 TO REPLACE BULB. TONIGHT THE PASSENGER SIDE HEADLIGHT ALSO WENT OUT. IT WILL GO BACK ON IF WE TURN OFF THE HEADLIGHTS THEN TURN THEM BACK ON. WE LIVE OUTSIDE OF CITY LIMITS. IMAGINE DRIVING IN THE DARK AND YOUR HEADLIGHTS GO OUT. *TR

WE HAVE A 2005 PRIUS. THE PASSENGER SIDE HEADLIGHT STARTED TO FLICKER ABOUT A MONTH AGO. FINALLY FAILED COMPLETELY. ESTIMATE FOR REPLACING BOTH BULBS 105.00 LABOR 376.00 FOR EACH BULB. TOTAL OF $850.00. THIS IS CRAZY AND UNSAFE. I AM FORCED TO DRIVE AROUND WITH ONE HEADLIGHT OUT, WAITING FOR THE OTHER TO FAIL, BECAUSE I DON'T HAVE $850.00. THE CAR ONLY HAS 53,000 MILES ON IT. THIS IS JUST WRONG. TOYOTA NEEDS TO DO SOMETHING TO FIX THIS PROBLEM. *TR

EVENTS LEADING TO FAILURE: ORDINARY DRIVING. THE FAILURE: RIGHT HEADLIGHT STOPS WORKING. FREQUENCY: HARD TO TELL SINCE I CAN'T SEE THE HEADLIGHTS WHILE DRIVING. CAN ONLY GET INDIRECT EVIDENCE SUCH AS LIGHT REFLECTING FROM THE CAR IN FRONT OF ME-IF IT IS CLOSE. WHEN I FIRST NOTICED THIS, ABOUT A YEAR AGO, IT WAS INFREQUENT. THE FREQUENCY HAS INCREASED AS FAR AS I CAN TELL TO THE POINT THAT I BELIEVE IT IS DAILY NOW, ALTHOUGH STILL NOT CONSTANT. NO CONSEQUENCES SO FAR, BUT POTENTIAL FOR WRECKS AT NIGHT IS OBVIOUS, AND DRIVING WITHOUT HEADLIGHTS IS A CRIME, I THINK-CERTAINLY UNWISE. OVER THE LAST YEAR I HAVE TAKEN THE CAR INTO THE DEALER TWICE WHEN I THOUGHT THE HEADLIGHT WAS MALFUNCTIONING, BUT WHEN I GOT TO THE DEALER, IT WAS ON. TODAY WHEN I TOOK IT IN, IT WAS MALFUNCTIONING. AT THE DEALERSHIP OVER THE LAST YEAR, I HAVE BEEN QUOTED REPAIR PRICES BY THE DEALER, FROM $600 TO $1700 (FOR BOTH LIGHTS), THE LATTER BEING RECOMMENDED. THE REQUEST FOR INCIDENT DATE BELOW IS INAPPROPRIATE SINCE THERE HAVE BEEN HUNDREDS OF INCIDENT DATES. I AM COMPLETING IT SINCE THE FORM WILL NOT ALLOW ME TO CONTINUE IF I DON'T SELECT A SINGLE DATE. THE SELECTION OF ONE DATE BELOW IS NOT A WAIVER OF THE MANY OTHER DATES. *TR

ABOUT 3 MONTHS AGO MY HEADLIGHTS ON MY 2005 PRIUS STARTED TO GO OUT THEN COME BACK ON. AT FIRST I ASSUMED IT WAS A HEADLIGHT THAT NEEDED TO BE REPLACED BUT WHEN I WAS GOING TO BUY THE HEADLIGHTS I WAS TOLD IF IT WAS A DEAD HEADLIGHT...IT WOULD NEVER COME BACK ON. MY WARRANTY WAS ABOUT TO EXPIRE. I TOOK IT INTO THE DEALER IN WISCONSIN AND THEY SAID THEY HAD FIXED IT. HOWEVER I COULD SEE UP AGAINST THE WALL THAT IT WAS NOT. I TOLD THEM I WOULD NOT LEAVE TILL THEY FIXED IT. THEY GAVE ME BACK THE CAR AND THE HEADLIGHTS WORKED FOR A FEW DAYS THEN STARTED THE ON OFF THING AGAIN. PROBLEM IS YOU ARE NOT SURE WHEN IT HAPPENS...IF THE ROAD IS LIT AT ALL IT'S HARDER TO TELL. BUT I WHEN I HAD TO MAKE A TRIP OUT EAST THERE WERE ROADS WITH NO LIGHT SO ALL THAT WAS SEEN WAS THE PARKING LIGHTS. I THOUGHT I WAS GOING BLIND. I HAVE HEARD FROM OTHERS THAT THIS HAS HAPPENED TO MANY AND I WILL BE JOINING A CLASS ACTION LAW-SUIT. THIS IS LIFE THREATENING AND TOYOTA KNOWS VERY WELL ABOUT IT AND ALL THE DEALERS ARE JUST PRETENDING NOT TO. THERE MUST BE A RECALL RIGHT AWAY!!!! TO ADD INSULT TO INJURY, NOW THE AIR CONDITIONING HEATING IS ALL MESSED UP AND MY WINDOWS FOG UP AND I CAN'T GET THEM TO CLEAR. IT'S A MESS! *TR

I HAVE A 2005 TOYOTA PRIUS (PKG 6) WITH APPR. 18,000 MILES. ABOUT A MONTH AGO, BY DRIVER'S SIDE HEADLIGHT STARTED TO GO OUT (GOING OFF AND ON) UNTIL IT FINALLY WENT OUT COMPLETELY. ON FEBRUARY 27, 2009, I TOOK THE VEHICLE INTO THE DEALER (LONGO TOYOTA IN EL MONTE, CALIFORNIA), WHO TOLD ME I WOULD HAVE TO SPEND $358 (PARTS AND LABOR) FOR JUST THE ONE HEADLIGHT. AFTER MUCH DISCUSSION WITH THE SERVICE REP AT THE DEALER AND THE TOYOTA SALES REP, TOYOTA AGREED TO PAY FOR THE REPLACEMENT OF BOTH HEADLIGHTS WITH ME PAYING FOR THE LABOR OF THE REPLACEMENT. THE TOTAL COST TO ME FOR THE LABOR WAS $201.76. IF TOYOTA HADN'T AGREED TO PAY FOR THE REPLACEMENT OF THE BULBS, I WOULD HAVE BEEN OUT OF POCKET $716.14 (PARTS AND LABOR). AS IT WAS, I STILL HAD TO PAY $201.76 FOR THE LABOR. IT IS MY OPINION THAT A VEHICLE THAT IS ONLY 3-1/2 YEARS OLD SHOULD NOT HAVE TO HAVE IT'S HEADLIGHTS REPLACED. I ALSO UNDERSTAND FROM TALKING TO THE SERVICE REP AND DOING FURTHER RESEARCH THAT THIS IS A COMMON OCCURRENCE EVEN IN MUCH YOUNGER PRIUS'. I FEEL THAT THIS PROBLEM NEEDS TO BE RESEARCHED FURTHER BY THE NHTSA AND A DETERMINATION MADE ON WHETHER THERE NEEDS TO BE AN OFFICIAL RECALL FOR THE HEADLIGHT REPLACEMENT PROBLEM ON PRIUS'. *TR

ABOUT 6 WEEKS AGO I BEGAN EXPERIENCE A RANDOM SHUT DOWN OF MY PS HEAD LIGHT. ONLY BE TURNING MY LIGHTS OFF AND BACK ON RESTORED IT FOR SOME AMOUNT OF TIME.. LAST WEEK THE SAME THING STARTED HAPPENING WITH THE DS HEADLIGHT. NOW ETHER ONE OR BOTH RANDOMLY JUST GOES DARK. WHEN BOTH GO OUR ON A TWO LANE ROAD IT GETS REALLY DARK. I CAN NOT CAUSE IT TO HAPPEN AND CAN NOT FIND ANYTHING THAT LOOKS LOOSE. IT SOMETIMES HAPPENS WHEN THE CAR IS SITTING STILL AT AN INTERSECTION. SOME NIGHTS IT HAPPENS SEVERAL TIME IN A 2 MILE DRIVE TO THE STORE AND OTHER TIMES (RARELY NOW) IT DOES NOT HAPPEN AT ALL. HEAT DOE NOT SEEM TO BE AN ISSUE SINCE IT SOMETIME HAPPENS JUST AFTER THE CAR IS STARTED FROM COLD. WHEN CHECKING THE INTERNET IF FIND THE PRIUS HEADLIGHT PROBLEM PRODUCES SEVERAL BLOG AND OTHER SITES THAT DESCRIBE THE SAME THING WITH PEOPLE SAYING THAT THE DEALERSHIPS DON'T KNOW HOW TO SOLVE THE PROBLEM EVEN THOUGH SOME PEOPLE HAVE SPENT OVER $2500 SWAPPING OUT PARTS.. AS A RESEARCHER, I CONCLUDE THAT THIS IS CLEARLY VEHICLE CLASS PROBLEM THAT SHOULD AT LEAST BE UNDERSTOOD BY THE SERVICE CENTERS. AS A DRIVER, IT IS CLEARLY A DANGEROUS SAFETY ISSUE.

THE DRIVER'S SIDE HEADLIGHT ON MY 2005 PRIUS WAS GOING ON AND OFF AND THEN WENT OUT ALL TOGETHER AFTER ABOUT 3 WEEKS. WHEN I TOOK IT TO THE TOYOTA DEALER THEY SAID THE BULB AND LABOR WOULD BE $320 AND THE COMPUTER THAT CONTROLS THAT ONE HEADLIGHT WAS ALSO OUT AND THAT WOULD BE $250 - SO IT WOULD BE ALMOST $600 FOR 1 HEADLIGHT!! I THINK AFTER READING MANY OTHER PRIUS OWNER'S SIMILAR COMPLAINTS ON THE INTERNET THAT THIS IS A DESIGN FLAW AND ALSO AN OUTRAGEOUS, UNFAIR CHARGE TO CONSUMERS FOR AN ITEM THAT MUST HAS TO WORK IN ORDER TO USE THE CAR. I FEEL BEFORE I BOUGHT THE CAR I SHOULD HAVE BEEN INFORMED OF THE COST TO REPAIR A HEADLIGHT AND THAT SOME PRIUS' HAVE REGULAR HEADLIGHTS ON THEM AND I SHOULD HAVE BEEN GIVEN A CHOICE. *TR

ON THREE SEPARATE OCCASIONS MY HEADLAMPS HAVE GONE OUT. EACH TIME IT HAS BEEN THE RIGHT OR LEFT SIDE. THE FOURTH TIME. THE LIGHTS CAME ON USING THE HI-BEAM ONLY. NUMEROUS INCIDENTS HAVE TAKEN PLACE. THIS IS THE SECOND TIME MY WIFE HAS BEEN PULLED OVER FOR THIS. I HAVE REPLACED THESE MYSELF. HOWEVER, THIS LAST TIME IT IS NOT THE BULB. IT IS THE ELECTRICAL SYSTEM. ACCORDING TO THE FORUM. COSTS HAVE BEEN FROM $300 - 2K. SOME DEALERSHIPS ASSUME SOME RESPONSIBILITY AND OTHERS DON'T. THIS IS A SAFETY AND EXPENSE ISSUE. DRIVING HOME IS VERY DIFFICULT AT NIGHT AND USING THE HI-BEAM IS BLINDING TO ON COMING TRAFFIC AND AGAINST THE LAW IN MOST CIRCUMSTANCES. *TR

OUR 2005 PRIUS RECENTLY DEVELOPED A PROBLEM WITH THE AUTOMATIC-LEVELING HEADLIGHTS. WARNING SYMBOLS APPEARED ON THE DASH. AS WE WERE DRIVING, WE NOTICED THAT THE HEADLIGHTS WERE AIMED MUCH HIGHER THAN USUAL, SO THAT THE LOW BEAMS APPEARED MORE LIKE HIGH BEAMS. IN THE COURSE OF THIS TRIP, WE STOPPED BRIEFLY AND TURNED OFF THE CAR. WHEN WE RESUMED OUR TRIP, WE NOTICED THE HEADLIGHTS WERE NOW VERY LOW, SO LOW THAT WE DARED NOT GO OVER ABOUT 20 MPH. WE SCHEDULED A VISIT TO OUR TOYOTA SERVICE DEPARTMENT; BUT WHILE THE WARNING LIGHTS WERE STILL ON, THE HEADLIGHTS WERE NOW AIMED NORMALLY. PRIOR TO THIS SERVICE VISIT, AN INTERNET SEARCH REVEALED THAT A NUMBER OF 2004-2005 PRIUSES HAVE EXPERIENCED A PROBLEM WITH THE SENSOR IN THE REAR OF THE CAR, IN THE VICINITY OF THE LEFT REAR TIRE WELL, THAT MEASURES THE LOAD ON THE REAR END AND ADJUSTS THE HEADLIGHTS ACCORDINGLY. TOYOTA HAS PUBLISHED A TECHNICAL SERVICE BULLETIN ON THE PROBLEM. IT APPEARS THAT IN A NUMBER OF PRIUSES, THE SENSOR IS DEFECTIVE, BUT THE PROBLEM IS INTERMITTENT AND DIFFICULT TO DETECT. I SHARED WITH THE DEALER WHAT I KNEW ABOUT THE PROBLEM, E-MAILED (AT THEIR REQUEST) THE TSB, AND ASKED THAT EVEN THOUGH OUR CAR WAS RECENTLY OUT OF WARRANTY, SINCE IT HAD ONLY 25,000 MILES ON IT AND THE PROBLEM WAS CLEARLY A SYSTEMATIC MANUFACTURING DEFECT AS WELL AS A POTENTIAL SAFETY HAZARD, THE MANUFACTURER SHOULD REMEDY THE PROBLEM AT NO CHARGE. DURING MY DISCUSSION WITH THE SERVICE ADVISER, HE ADMITTED THAT WHILE NO FAULT CODE COULD BE DETECTED, THE ONLY POSSIBLE CAUSE OF THE PROBLEM HAD TO BE THE SENSOR. THE SERVICE ADVISOR SAID THERE WAS NO WAY TOYOTA WOULD COVER THE REPAIR; THAT ALREADY IN THE PAST MONTH, 15 OF THESE UNITS HAD TO BE REPLACED IN THE REGION AND NONE OF THEM HAD BEEN COVERED BY WARRANTY. HOWEVER, THE SERVICE ADVISOR INDICATED THE DEALERSHIP ITSELF WOULD COVER THE PART ($470) IF I AGREED TO PAY FOR THE INSTALLATION ($200). I DID SO AND THE PROBLEM HAS NOW BEEN REMEDIED. *TR

2005 TOYOTA PRIUS...PURCHASED NEW...HAVE HAD NINE (9) EXTERIOR LIGHTS BURN OUT. I HAVE REPLACED THEM AND THEY SEEM TO BE WORKING BETTER. I BELIEVE THE BULBS USED BY TOYOTA WERE INFERIOR. AFTER 36,000 MILES TOYOTA WOULD NOT REPLACE ANY BULBS. *TR

2005 TOYOTA PRIUS HEADLIGHTS GO OFF SPONTANEOUSLY. USUALLY JUST THE DRIVERS SIDE BUT RECENTLY BOTH AT THE SAME TIME. BEFORE TURNING THE LIGHTS OFF AND BACK ON WOULD FIX IT BUT NOW IT DOES NOT ALWAYS WORK. PREVIOUS OWNER HAD IT CHECKED BY TOYOTA BUT THEY COULD NOT FIND ANYTHING WRONG. *TR

DRIVER'S SIDE HEADLIGHT BEGAN GOING OUT INTERMITTENTLY, FIRST RARELY, THEN GRADUALLY MORE FREQUENTLY. SWITCHING THEM OFF AND ON WOULD RESTORE IT TEMPORARILY. THE FIRST TIME I TOOK IT TO THE DEALER THEY COULDN'T REPRODUCE THE PROBLEM. BY THE TIME IT BECAME VERY BAD, THEY DIAGNOSED THAT THE HEADLAMP WAS OVERHEATING, AND REPLACED IT ($360). NOW, LESS THAN TWO MONTHS LATER IT HAS STARTED GOING OUT AGAIN, AT INFREQUENT INTERVALS. THIS IS CLEARLY A SAFETY ISSUE AND NEEDS TO BE INVESTIGATED. *TR

WE NOTICED SHORTLY AFTER WE BOUGHT OUR 2005 TOYOTA PRIUS THAT THE HEADLIGHTS DID NOT SHINE FAR ENOUGH IN ADVANCE OF THE CAR TO PROPERLY ILLUMINATE THE ROAD. WHEN WE COMPLAINED TO THE DEALER, THEY CHECKED IT AND SAID THAT THE LIGHTS WERE SET PROPERLY SO AS NOT TO SHINE IN THE FACE OF APPROACHING CAR. NOW THE AUTOMATIC SENSOR WARNING LIGHT WARNING OF A PROBLEM ILLUMINATES AND INDICATES HEADLIGHT PROBLEMS ANY TIME WE HAVE ANYONE IN THE BACK SEAT OF THE CAR. DESPITE HAVING HIGH INTENSITY HEADLIGHTS OFFERED IN THIS PACKAGE (PACKAGE 4), WE STILL DO NOT FEEL SAFE DRIVING THIS CAR AT NIGHT BECAUSE THE HEADLIGHTS ILLUMINATE ONLY ABOUT 15-20 FEET IN FRONT OF THE CAR, EVEN AT 'HIGH BEAMS.' I DON'T WANT TO BLIND SOMEONE, BUT I DO WANT TO SEE THE ROAD MORE THAN 20 FEET IN FRONT OF ME. I AM INDICATING THE PROBLEM BEGAN IN MAY, 2008 BECAUSE THAT'S WHEN THE SENSOR WARNING LIGHT STARTED TO COME ON, BUT THIS HAS BEEN A PROBLEM WITH THIS CAR PRETTY MUCH EVER SINCE WE BOUGHT IT. THE DEALER SAYS THERE IS A BULLETIN OUT ABOUT IT, BUT WANTS TO CHARGE US ABOUT $500 TO FIX IT SINCE IT IS 8,000 MILES PAST WARRANTY. HAD I KNOWN THAT OTHERS HAVE IDENTIFIED THIS AS A PROBLEM (WWW.PRIUSCHAT.COM), I WOULD HAVE BEEN MORE INSISTENT BEFORE THE WARRANTY RAN OUT. THIS CAR REALLY IS UNSAFE TO DRIVE AT NIGHT, ESPECIALLY HERE IN RURAL MAINE WHERE WE HAVE MANY LARGE ANIMALS ON THE HIGHWAYS AT NIGHT (INCLUDING MOOSE). *TR

MY 2005 PRIUS STARTED TO INTERMITTENTLY DISPLAY A WARNING TRIANGLE SIGN ON THE DASHBOARD. FINALLY IT CAME ON AND STAYED ON. THE DEALER PERFORMED A DIAGNOSTIC CHECK AND SAYS THERE IS SOMETHING WRONG WITH THE HEADLIGHT LEVELING SYSTEM - A SHORT OR SOME SUCH GLITCH. COST TO REPAIR $700. I DECLINED TO REPAIR SINCE IT WAS OUT OF WARRANTY. IT APPEARS THAT THERE ARE OTHER PRIUS PROBLEMS WITH HEADLIGHTS. *TR

TOYOTA'S HID HEADLIGHTS SEEM TO ONLY WORK INTERMITTENTLY. TOYOTA WOULD LIKE US TO REPLACE THE BULBS. LABOR AND THE BULB RUN ABOUT $500. THIS SEEMS TO BE A PROBLEM WITH MANY OF TOYOTA'S VEHICLES AND SEEMS LIKE CONSUMER GOUGING ON A FAULTY PRODUCT/DESIGN TO THE NTH DEGREE! *TR

I HAVE A 2005 TOYOTA PRIUS. ONE OF MY HID HEADLIGHTS BURNED OUT AFTER ONLY 35,000 MILES, JUST 3 MONTHS AFTER MY WARRANTY EXPIRED. TOYOTA CLAIMS ON THEIR WEBSITE THAT HID HEADLIGHTS LAST LONGER THAN HALOGEN BULBS, BUT BY E-MAIL SAID THAT THEY HAD NOT DETERMINED LIFE EXPECTANCY OF PARTS IN MY VEHICLE. LOOKING AT THE MANY PRIUS CHAT ROOMS ON THE WEB, THIS IS NOT AN UNUSUAL PROBLEM. AS THE REPLACEMENT PART ALONE (A SINGLE BULB) RUNS $350, THERE IS A SUBSTANTIAL PROBLEM WITH HAVING TO REPLACE THE BULB SO SOON AFTER THE WARRANTY EXPIRES. *TR

2005 TOYOTA PRIUS HID DRIVER'S HEADLIGHT CONTINUES TO INTERMITTENTLY FAIL TO ILLUMINATE. DEALER WANTS >$600 TO REPLACE HEADLIGHT. PROBLEM WELL DOCUMENTED AS RECURRENT ISSUE FOR PRIUS WITH HID HEADLAMPS. THIS SHOULD BE ADDRESSED BY TOYOTA ASAP. IT IS VERY DANGEROUS TO LOSE HEADLIGHTS WHILE DRIVING. IT IS ALSO OUTRAGEOUS TO EXPECT CONSUMERS TO PAY $600 TO REPLACE A LIGHT BULB AND NOT EVEN BE ABLE TO GUARANTEE THAT WILL SOLVE THE PROBLEM. *TR

MY VEHICLE IS A 2005 TOYOTA PRIUS WITH TRIM PACKAGE #9, INCLUDING HIGH-INTENSITY DISCHARGE (HID) HEADLAMPS - THE ONLY ONES AVAILABLE IN THE ONLY VEHICLE AVAILABLE TO ME, SO THESE WERE NOT AN OPTIONAL PURCHASE. I WAS CONFIDENT IN THE EXPECTED LONG SERVICE LIFE OF HID BULBS BUT HAD ONE FAIL AT 41,000 MILES IN A PATTERN VERY SIMILAR TO OTHERS DESCRIBED ONLINE - INTERMITTENT DIFFICULTY GETTING ONE HEADLIGHT TO TURN ON, FOLLOWED BY DIMMING AND A PINK TINT IN THE LIGHT, AND FINALLY COMPLETE FAILURE. DESPITE THE HISTORY OF PRIUSES HAVING EARLY HID FAILURE, THE DEALER WAS ONLY ABLE TO SUGGEST THAT I PAY FOR A BULB REPLACEMENT, FOR ABOUT $350. GIVEN THAT HID LIGHTING SYSTEMS ARE SUPPOSED TO BE MUCH LONGER LIVED THAN THIS, I MUST SUSPECT THAT THERE IS A FLAW IN THE PRIUS'S HID ELECTRONICS THAT IS CAUSING BULBS AND/OR OTHER COMPONENTS IN THE HID LIGHTING CHAIN TO FAIL MUCH SOONER THAN EVER EXPECTED, IF NOT UNEXPECTEDLY. *TR

THE PASSENGER SIDE HID HEADLIGHT ON MY 2005 TOYOTA PRIUS TURNS OFF SPONTANEOUSLY AT RANDOM TIMES. IT WILL TURN ON AGAIN IF I TURN THE LIGHTS OFF AND ON, BUT IT WILL INEVITABLY TURN OFF AFTER 1 TO 10 MINUTES OF DRIVING. THE CAR HAS NEVER BEEN IN AN ACCIDENT AND HAS 39,000 MILES ON IT. THE DEALER-TRAINED "MASTER MECHANIC" RAN A DIAGNOSTIC TEST AND CLAIMS THAT THE "HID ECU" (HID ELECTRONIC CONTROL UNIT, PART NUMBER 8110747150) IS MALFUNCTIONING AND MUST BE REPLACED. IT COSTS $320 IN LABOR TO ACCESS THE HID ECU UNDER THE DASHBOARD, AND $286.99 FOR THE NEW COMPUTER. THERE ARE DOZENS OF COMPLAINTS ABOUT THE HID LIGHTS TURNING OFF FOR NO APPARENT REASON ON VARIOUS PRIUS BULLETIN BOARDS ON LINE, YET TOYOTA'S CUSTOMER SATISFACTION CENTER CLAIMS TO HAVE NO RECORDS OF THIS PROBLEM, AND CLAIMS THERE IS NO RECALL OR SERVICE BULLETIN. HEADLIGHTS FAILING AT RANDOM DUE TO A MANUFACTURER'S DEFECT IS A SERIOUS SAFETY ISSUE THAT TOYOTA SHOULD ADDRESS. *TR

HID HEADLAMPS GO OUT RANDOMLY AND INDIVIDUALLY, BUT CAN BE RELIT BY CYCLING THE HEADLIGHT SWITCH ON AND OFF.

TOYOTA SIENNA ...AT APPROX 36K MILES MY HEADLIGHTS WOULD INTERMITTENTLY GO OFF. BULBS WERE REPLACED AND THE PROBLEM PERSISTED. THE ECU UNIT TO THE HEADLIGHT WAS REPLACED AND WORKED FINE FOR A YEAR. NOW AT 59K THE HEADLIGHTS ARE DOING THE SAME. I AM TOLD AGAIN TO REPLACE THE BULBS(300$) EACH. THE BULBS COME ON BUT JUST GO OUT ON THERE OWN WITHOUT HITTING A BUMP . IT VARIES WHICH LIGHT I WILL HAVE AND I HAVE LOST BOTH WHILE TRAVELING. I THINK THIS IS VERY DANGEROUS. THE DEALERSHIP IS REPLACING BULBS THIS WEE....HOPE IT WORKS. *TR

TL*THE CONTACT OWNS A 2005 TOYOTA PRIUS. WHILE BEING SERVICED AT THE DEALER, THEY NOTICED THAT THE HEADLIGHTS WERE DISTORTED. THE PLATING ON THE INTERNAL PART OF THE HEADLIGHTS WERE OVERHEATING. THERE IS NO WAY TO RELEASE THIS HEAT AND THE CONTACT IS CONCERNED THAT A POSSIBLE FIRE MAY OCCUR. THE VEHICLE WAS TAKEN TO THE DEALER, BUT THEY DID NOT WANT TO BE RESPONSIBLE BECAUSE IT WAS NO LONGER UNDER WARRANTY. THE FAILURE MILEAGE WAS 40,000 AND CURRENT MILEAGE WAS 41,000.
