2004 TOYOTA PRIUS Exterior Lighting Problems

ALL THE INSTRUMENT CLUSTER LIGHTS CONTINUE TO GO OUT ON MY 04 PRIUS. I DON'T KNOW HOW MUCH FUEL I HAVE THIS COULD BE A SAFETY ISSUE. I DON'T KNOW HOW FAST I'M GOING THIS COULD DEFINITELY BE A SAFETY ISSUE. AND ZERO WARNING LIGHTS COME ON THIS IS DEFINITELY A SAFETY ISSUE. BY LOOKING ON THE INTERNET I CAN TELL THOUSANDS OF PRIUSES HAVE THIS EXACT SAME ISSUE WITH THE INSTRUMENT PANEL CLUSTER GOING OUT. THIS SHOULD DEFINITELY BE A RECALL.

MY LEFT HEADLIGHT GOES OFF BUT IF I TURN THE HEADLIGHTS BACK OFF AND BACK ON IT COMES BACK ON. THE HEADLIGHT IS NOT BURNED OUT. THIS HAPPENS WHILE ON THE FREEWAY IN THE DARK WHILE RAINING. THIS HAPPENS INTERMITTENTLY AND NOT ALL THE TIME.

ABOUT 1.5 YEARS AGO DURING A VACATION. MY CAR DECIDED TO NOT SHUT OFF. I DROVE TO THE NEAREST DEALERSHIP THAT WAS ABOUT THE CLOSE. THEY ASSISTED AND SAID TO HOLD THE POWER BUTTON DOWN UNTIL IT SHUTS OFF THEN TURN IT BACK ON. THIS WAS A DEALERSHIP IN GEORGIA. THE MECHANIC HAD HEARD OF THE PROBLEM BEFORE. I RECENTLY HAD THE FRONT DASH LIGHT GO COMPLETELY OUT. I DID NOT HAVE AN INSTRUMENT PANEL AT ALL. THE WAS NOT A WAY TO SEE MPH, GAS GAUGE, WARNING LIGHTS, NOTHING. THE CENTER MONITOR STAYED ON. IT TOOK 2 DAYS BUT IT CAME BACK ON. A WEEK LATER IT HAPPENED AGAIN AND AGAIN CAME BACK ON. WARNING LIGHTS CAME ON AND I DROVE TO DEALERSHIP. IT WAS THE 2ND WATER PUMP GOING OUT. AS I WAS LEAVING MY DASH LIGHTS WENT OUT AGAIN. I TOOK IT BACK INTO THE PRIUS DEALERSHIP. THEY HAD PAPERWORK STATING THERE HAD BEEN ISSUES WITH THE METERED DASH BEFORE. IS THERE A RECALL ON IT OR NOT? I HAD TO HAVE A CAR AND WAS ALLOWED TO LEAVE WITH THE DASH NOT WORKING. I DROVE TO A GAS STATION. AFTER FILLING WITH GAS THE DASH LIGHTS CAME ON AGAIN. I HAD TO PAY FOR THE METERED DASH PART TO BE ORDERED UP FRONT BECAUSE THE MECHANIC SAID IT MAY COME BACK ON. THERE SHOULD BE A RECALL ON THIS AS IT IS AN ONGOING ISSUE. THE MECHANIC EVEN CALLED IT A SHORT. DUE TOT HE PAPERWORK THE DESK REPRESENTATIVE HAD, IT APPEARS THERE HAVE BEEN SEVERAL REPORTS BEFORE ON THE METERED DASH SHORTING. PLEASE HELP. I NEED THE CAR AND CANNOT AFFORD THESE RIDICULOUS PRICES FOR MANUFACTURER MISTAKES.

HEADLIGHT GO OUT DAILY AND HAPPENS WHILE DRIVING AT NIGHT FROM WORK, THEY TURN BACK ON SWITCH ON AND OFF

MY CAR HEAD LIGHTS ARE TURNING OFF, AT FIRST IT WAS ONE NOT TURNING ON AND THEN IT WAS THE OTHER ONE, NOW THEY TAKE TURNS. IT IS A SAFETY ISSUE WHICH ALMOST HAD MAKE ME CRASH MORE THAN 2 TIMES. TO THE POINT THAT I AM UNABLE TO USE THE CAR DURING THE NIGHT. THIS HAPPENS IF THE CAR IS PARKED OR RUNNING.

3 DAYS AFTER BUYING MY 04 PRIUS BOTH OF MY LOW BEAMS AND ONE OF MY HIGH BEAMS WENT OUT. A FEW MONTHS AFTER REPLACING THEM MY DRIVER SIDE LOW BEAM WENT OUT, THE HIGH BEAM WAS FINE. 2-3 MONTHS AFTER RE REPLACING THE DRIVER'S SIDE LOW BEAM THE PASSENGER SIDE LOW BEAM WENT OUT. I HAVE HAD TO REPLACE MY HEADLIGHTS ABOUT 5 TIMES EACH (10 TIMES TOTAL DRIVER+PASSENGER SIDE) I HAD MY GROUND WIRES CHECKED, I CONSTANTLY CHECK MY FUSES, MECHANICS SAY NOTHING IS WRONG WITH MY LIGHTING, BUT HERE I AM WITH THIS REOCCURRING ISSUE. I HAVE BEEN USING THE SAME KIND OF BULBS BECAUSE I CAN'T IMAGINE SPENDING MORE MONEY ON A BULB TO HAVE IT BLOW OUT IN A COUPLE OF MONTHS (XTRAVISION 9003 12.8V,55/60W HALOGEN). APPARENTLY MY REVERSE LIGHTS AREN'T WORKING EITHER, AND ONE OF MY LICENSE PLATES LIGHTS IS OUT (I THINK THE PLATE LIGHT IS PROBABLY NOT CONNECTED TO THE OTHER LIGHTS GOING OUT) ZI DO THINK THE REVERSE LIGHTS ARE A RELATED PROBLEM THOUGH. MY LIGHTS GO OUT BOTH IN MOTION AND STATIONARY (I COULDN'T TELL YOU IF IT HAPPENS ON TURNS OR NOT, BUT IT CAN HAPPEN ON HIGHWAYS), SOMETIMES I CAN GET THEM TO COME BACK ON BY GIVING A LITTLE SMACK, BUT USUALLY A FEW DAYS AFTER THAT THEY OFFICIALLY BURN OUT. I'VE RESEARCHED THIS PROBLEM ON PRIUS FORUMS AND APPARENTLY I AM NOT THE ONLY PRIUS OWNER EXPERIENCING THIS WITH THE SAME FREQUENCY, THERE ARE NO RECALLS FOR THIS ISSUE, YET SO MANY OF US ARE EXPERIENCING THIS, WHICH IS QUITE DETRIMENTAL TO OURS AND OTHERS SAFETY. SOMETIMES I CAN'T TELL MY LIGHTS HAVE GONE OUT TIL I GET PULLED OVER OR AM ABLE TO SEE MY HEADLIGHT REFLECTION ON ANOTHER VEHICLE, EVEN WORSE IS WHEN I'M WONDERING WHY I CAN'T SEE ANYTHING WHEN IT'S SO DARK OUT JUST TO FOUND OUT ONE OF MY HEADLIGHTS BLEW AGAIN. I STILL OWN THIS VEHICLE AND STILL TRYING TO FIGURE OUT WHY THIS IS A CONTINUOUS PROBLEM.

OUR 2004 PRIUS HAS INTERMITTENT PROBLEMS WITH HEADLIGHTS AND TAIL LIGHTS FAILING. ONE OF BOTH HEADLIGHTS WILL ALL OF A SUDDEN GO OUT. TURNING THEM OFF AND ON USUALLY CAUSES THEM TO COME BACK ON. MY SON WAS DRIVING ON A CURVY, DARK FORESTED ROAD WHEN BOTH LIGHTS WENT OUT. COULD NOT SEE A THING. THIS IS AN EXTREMELY DANGEROUS SITUATION. WE HAVE ALSO REPLACED TAIL LIGHT BULBS. THEY WORK, THEN FAIL AGAIN QUICKLY.

Mileage: 260,000

THE PASSENGER SIDE HEADLIGHT GOES OUT WHILE OPERATING THE VEHICLE. IT BEGINS TO OPERATE AGAIN AFTER TURNING HEADLIGHTS OFF AND ON AGAIN. THIS HAPPENS MULTIPLE TIMES DURING VEHICLE OPERATION IN A SINGLE DRIVE. FOR EXAMPLE, THREE TIMES TODAY WITHIN 15 MINUTES. THE HEADLIGHT WAS REPLACED WITHIN THE LAST 6 MONTHS, BUT WE NOW BELIEVE IT IS A SYSTEMIC ISSUE, UNRELATED TO THE BULB ASSEMBLY, BECAUSE IT HAS OCCURRED WITH TWO BULBS IN A ROW. THIS OCCURRED BOTH WHEN THE VEHICLE IS IN MOTION AND WHEN STATIONARY (IDLING).

Mileage: 153,040

WHEN DRIVING ON THE INTERSTATE IN THE DARK, BOTH MY HEADLIGHTS WENT OUT. LUCKILY THEY CAME BACK ON AFTER I TURNED THE SWITCH OFF AND BACK ON.

Mileage: 166,000

OVER THE PAST FEW MONTHS MY HEADLIGHTS WOULD RANDOMLY TURN OFF WHILE I'M DRIVING. SOMETIMES IT'S ONE HEAD LIGHT, OTHER TIMES IT'S BOTH. USUALLY THEY TURN BACK ON IF I TURN THEM OFF THEN BACK ON. THE OTHER DAY THEY TURNED OFF FOR ABOUT 20 SECONDS WHILE I WAS DRIVING 70MPH DOWN THE INTERSTATE AT 10PM. I SAW MY LIFE FLASH BEFORE MY EYES. THEY WOULD NOT TURN BACK ON FOR 20 SECONDS APPROXIMATELY. UPON FURTHER RESEARCH ON A PRIUSCHAT FORUM, I SAW THAT LOTS OF OTHER PEOPLE HAVE HAD THIS ISSUE. THERE WAS EVEN A CLASS ACTION LAWSUIT AGAINST TOYOTA BECAUSE THEY KNEW ABOUT THE ISSUE BUT DID NOT RECALL. I'M A SINGLE PARENT AND I DEPEND ON MY CAR AND MY SON NEEDS HIS MOM. TOYOTA NEEDS TO FIX THERE ERROR AND RECALL THE HEAD LIGHTS.

Mileage: 125,000

HELLO TEAM, ONE OF THE HEADLIGHTS KEEPS GOING OUT. I CAN'T REALLY TELL WHEN OR HOW IT GOES OUT SINCE I CAN'T SEE IT. I'LL NOTICE IT WHEN I SEE THE REFLECTION IN THE BACK OF ANOTHER CAR. IF I TURN THE BRIGHT LIGHTS ON AND OFF IT HAS NO EFFECT, BUT WHEN I TURN THEM ALL THE WAY OFF AND BACK ON THE LIGHT COMES BACK. SOMETIMES ON LONG TRIPS IT WILL STAY ON THE WHOLE TIME, SOMETIMES IT WON'T. SOMETIMES ON SHORT TRIPS IT WILL GO OUT, SOMETIMES IT WON'T. IT IS NOT AN EVENT I CAN MAKE HAPPEN.

Mileage: 122,500

HEADLIGHTS WOULD RANDOMLY GO OUT COMPLETELY AND WOULD VERY QUICKLY HAVE TO TURN THEM OFF AND THEN BACK ON TO GET THEM TO WORK. THIS DID NOT HAPPEN VERY OFTEN BUT THEY DID OCCUR UNEXPECTEDLY AND CAUSED EXTREMELY UNSAFE CONDITIONS WHILE DRIVING.

THE PASSENGER SIDE BRAKE LIGHT DOES NOT WORK.

Mileage: 130,000

HEADLIGHTS WOULD RANDOMLY GO OUT COMPLETELY AND WOULD VERY QUICKLY HAVE TO TURN THEM OFF AND THEN BACK ON TO GET THEM TO WORK. THIS DID NOT HAPPEN VERY OFTEN BUT THEY DID OCCUR UNEXPECTEDLY AND CAUSED EXTREMELY UNSAFE CONDITIONS WHILE DRIVING. ADDITIONALLY, THE HEADLIGHTS WOULD BARELY ILLUMINATE THE ROAD AT NIGHT ALL THE TIME WHILE DRIVING IN ALL CONDITIONS AND ON ALL ROADS, AND THE AREA THEY ILLUMINATED WAS ONLY A VERY SHORT DISTANCE IN FRONT OF THE CAR SO THIS ALSO CREATED UNSAFE CONDITIONS AT ALL TIMES. TO COMPENSATE I WOULD TURN ON THE HIGH BEAMS AND THEN THE PROPER AREA OF THE ROAD WOULD BE ILLUMINATED. THIS MADE ME HAVE TO SWITCH FROM LOW TO HIGH BEAM ON A REGULAR BASIS AND WAS EXTREMELY DISTRACTING HAVING TO DO SO WHENEVER AN ONCOMING CAR APPROACHED! I RECENTLY PAID ABOUT $350-375 TO HAVE THEM RELAMPED AND THAT HELPED BUT ONLY A VERY SMALL AMOUNT. THIS IS STILL A BIG PROBLEM AND MAKES ME NOT WANT TO DRIVE THIS CAR AT NIGHT!!! *TR

DESCRIPTION OF THE PROBLEM: THE H.I.D. HEADLIGHTS ON MY 2004 PRIUS FAILS UNEXPECTEDLY (THEY TURN OFF RANDOMLY, ON THEIR OWN). THIS PROBLEM AFFECTS MAINLY THE RIGHT HEADLIGHT. THE RIGHT HEADLIGHT FAILS VERY FREQUENTLY (HUNDREDS OF TIMES DURING THE LAST 12 MONTHS). THE LEFT HEADLIGHT FAILS SPORADICALLY (LESS THAN 10 TIMES DURING THE LAST 6 MONTHS). THIS ISSUE AFFECTS BOTH LOW BEAM AND HIGH BEAM HEADLAMPS SIMULTANEOUSLY. WHEN A HEADLIGHT FAILS, I TURN OFF THE LIGHTS THEN I TURN THEM BACK ON. THIS BRINGS BACK THE LIGHTS. THEN THE FAILURE OCCURS UNEXPECTEDLY AFTER SECONDS, MINUTES, OR HOURS. THIS ISSUE HAS OCCURRED WHILE MY VEHICLE WAS STATIONARY, IN MOTION, ON A CITY STREET OR A HIGHWAY, TURNING, BRAKING, ETC. THIS ISSUE ALSO OCCURS REGARDLESS OF ROAD CONDITIONS (SMOOTH FLAT ROADS & SPEED BUMPS / POTHOLES) OR WEATHER CONDITIONS (SUNNY, RAINY, SNOWY, WARM & COLD OUTSIDE TEMPERATURES). THIS IS A MAJOR SAFETY CONCERN, ESPECIALLY WHEN DRIVING NIGHT TIME ON COMPLETELY UNLIT ROADS.

Mileage: 114,000

RIGHT HID HEADLAMP INTERMITTENTLY GOES OUT WHILE DRIVING AND DOES NOT GO BACK ON. HOWEVER, WHEN YOU SWITCH THE HEADLIGHT TOGGLE SWITCH OFF THEN ON AGAIN, RIGHT HID HEADLAMP GOES BACK ON. WHILE DRIVING FOR A DISTANCE OF 120 MILES LAST NIGHT, THIS HAPPENED 6 TIMES ON BOTH CITY AND HIGHWAY AND ROAD CONDITIONS IE. BUMPS ETC IS NOT A FACTOR SINCE IT HAPPENS ON A SMOOTH PAVED HIGHWAY AS WELL. THE OUTAGE CAN OCCUR A FEW MINUTES AFTER TURNING THE TOGGLE HEADLAMP SWITCH ON OR IT CAN STAY ON FOR 20 MILES THEN OUT AGAIN. SINCE THE CAR IS NEVER LEFT IDLING WITH THE HEADLAMPS ON, IT IS UNKNOWN WHETHER RIGHT HEADLAMP WILL GO OUT WHILE PARKED. HAVE READ IN THE PRIUS CHAT SITE THAT MANY OTHER DRIVERS HAVE EXPERIENCED SIMILAR PROBLEM AND DESPITE THE DEALER REPLACING THE HID BULB OR EVEN THE ENTIRE HEADLAMP ASSEMBLY WHICH IS OVER $1,100 THE PROBLEMS WERE NEVER FULLY RESOLVED. PLEASE REFER TO: HTTP://PRIUSCHAT.COM/THREADS/HEADLIGHT-PROBLEM.34584/

Mileage: 313,000

DRIVER'S SIDE HEADLIGHT WAS INTERMITTENT. I COULD JIGGLE THE SWITCH AND IT WOULD COME ON. THIS OCCURRED STATIONARY AND MOVING. I HAVE REPLACE THE HID BULB TWICE WITH SYLVANIA D2R. THE HEADLIGHT DOES NOT WORK NOW. DEALER WILL CHARGE OVER $500 FOR HEADLIGHT AND BALLAST REPAIRS--HIGHWAY ROBBERY. THIS PROBLEM STARTED AUGUST 2014.

Mileage: 155,000

THE LEFT HEADLIGHT HAS BEEN GOING OFF WHILE DRIVING. I'VE GOT THE 'SAFETY' PACKAGE #7 WITH SPECIAL HID HEADLIGHTS. WHEN I TURN THE LIGHTS OFF AND ON AGAIN, IT COMES BACK ON FOR AWHILE. TWO NIGHTS AGO BOTH HEADLIGHTS WENT OUT WHILE DRIVING. VERY SCARY! I WAS ON AN ON RAMP AND COULDN'T SEE AT ALL. THEY BOTH CAME BACK ON AFTER I TURNED THE SWITCH OFF AND THEN ON.

Mileage: 135,000

HEADLIGHTS TURN OFF WHEN DRIVING FOR ABOUT HALF AN HOUR. I HAVE TO TURN THE HEADLIGHTS OFF THEN BACK ON SO THEY CAN START WORKING AGAIN. I DO SEE THIS TO BE A SAFETY ISSUE SINCE I DRIVE OUT OF TOWN OFTEN AND USE THE FREEWAY MOST OF THE TIME AND IT IS JUST VERY HARD FOR ME TO BE TURNING ON AND OFF THE HEADLIGHTS AT A HIGH SPEED. THIS HAS OCCURRED SEVERAL TIMES AND IT'S NOT SAFE AT ALL. THIS HAPPENS AT ANY SPEED USUALLY WITHIN THE FIRST 30 MINUTES AND IT CONTINUOUSLY TURNS OFF.

WE'VE NOTICED THIS PROBLEM ONLY A FEW TIMES IN THE CAR SINCE WE'VE OWNED IT. THAT'S BEEN ABOUT 3 YEARS. WE SELDOM DRIVE AT NIGHT BUT WHENEVER WE HAVE IT'S ALWAYS BEEN AN ISSUE. USUALLY JUST THE LEFT GOES OUT AND RESETTING THE LIGHTS BROUGHT IT BACK ON. THIS PAST WEEK THE SAME THING STARTED TO HAPPEN AND RESETTING IT WORKED A FEW TIMES BUT THEN BOTH HEADLIGHTS WENT OUT AND RESETTING THE SWITCH DID NOTHING. THANKFULLY DAWN WAS ON THE WAY AND WITH THE FOG LIGHTS ON WE JUST KEPT GOING. ONCE I FELT COMFORTABLE TURNING THE LIGHTS OFF COMPLETELY AND AFTER WAITING 3-5 MINUTES WITH THE SWITCH OFF I TRIED THE LIGHTS AND THEY CAME BACK ON. THERE IS DEFINITELY A PROBLEM WITH SOMETHING; MAYBE AN OVERHEAT ISSUE WITH THE BULBS, WIRING OR CONTROL BOX. THIS IS A HUGE DEAL. IF WE'D BEEN DRIVING INTO THE DARKNESS INSTEAD OF DAWN COULD EASILY HAVE HAD AN ACCIDENT.

Mileage: 126,500

AT AROUND 145,000 MILES THE RIGHT (PASSENGER) HEADLIGHT STARTED TURNING OFF RANDOMLY. IT WOULD COME BACK ON WHILE DRIVING IF I TURNED MY HEADLIGHTS OFF AND BACK ON. FREQUENCY HAS INCREASED OVER THE LAST 10,000 MILES. RECENTLY, THE LEFT HEADLIGHT WENT OUT WHILE ON THE FREEWAY AND THE RIGHT WAS ALREADY OUT, LEAVING ME WITH NO HEADLIGHTS. I HAD TO FLICK THEM ON AND OFF MULTIPLE TIMES AND FLICK THE BRIGHTS MULTIPLE TIMES TO GET THEM TO TURN BACK ON. I HAD NO HEADLIGHTS FOR AT LEAST 30 SECONDS WHILE ON THE HIGHWAY- THOUGH IN AN URBAN AREA WHERE OTHER LIGHTS ALLOWED ME TO SEE. TWICE, I HAVE BEEN LEFT WITHOUT HEADLIGHTS WHILE ON THE ROAD- ONCE ON THE HIGHWAY AND ONCE AT A STOP LIGHT (TURNING MY CAR OFF AND THEN BACK ON REVIVED THE LIGHTS).

HEADLIGHTS INTERMITTENTLY FLICKER AND SHUT OFF. IF HEADLIGHTS ARE TURNED OFF THEN BACK ON, BOTH HEADLIGHTS WILL WORK AGAIN. PROBLEM HAPPENS WHILE VEHICLE IS IN MOTION, AS WELL AS WHEN PARKED. THIS HAS HAPPENED SEVERAL TIMES WHILE DRIVING AT NIGHT, ON RURAL/POORLY LIT ROADS, AS WELL AS HIGHWAYS. USUALLY IT IS ONE LIGHT OR THE OTHER THAT GOES OFF, BUT ABOUT 5 DIFFERENT TIMES BOTH LIGHTS HAVE GONE OFF AT THE SAME TIME WHILE DRIVING AT NIGHT. ONE OF THESE INCIDENTS RESULTED IN A TRAFFIC STOP BY A POLICE OFFICER, WHO PROMPTLY ISSUED ME A TICKET FOR DRIVING WITH NO HEADLIGHTS ON. BOTH HEADLIGHT BULBS HAVE BEEN REPLACED; ALL FUSES HAVE BEEN CHECKED AND/OR REPLACED;12V BATTERY REPLACED - NONE OF WHICH HAS SOLVED THE PROBLEM.

Mileage: 100,000

DRIVER SIDE HEADLIGHT INTERMITTENTLY TURNS OFF WHILE DRIVING. DRIVER IS NOT AWARE HEADLIGHT IS NOT WORKING UNTIL POLICE PULLS HIM OVER OR AFTER RETURNING TO GARAGE AT HOME, HE CAN SEE FROM HEADLIGHT GLARE ON THE WALL THAT ONE LIGHT IS OUT. USUALLY TURNING THE LIGHT OFF, AND THEN BACK ON CORRECTS THE PROBLEM, HOWEVER YOU CANT BE DRIVING DOWN THE HIGHWAY FLASHING YOUR LIGHTS EVERY ONCE IN A WHILE TO MAKE SURE THEY ARE ON. IT IS JUST A DANGEROUS SITUATION. THE INTERNET SHOWS THIS IS A COMMON PROBLEM AND ITS FRUSTRATING THAT TOYOTA HAS NOT ACKNOWLEDGED OR PROVIDED A FIX.

Mileage: 100,000

I NOTICED THAT MY PASSENGER SIDE HEADLIGHT WAS OUT WHILE DRIVING HOME AT NIGHT. TWO DAYS LATER, AGAIN WHILE DRIVING AT NIGHT, MY PASSENGER SIDE HEADLIGHT WAS WORKING PERFECTLY. I HAVE DONE NOTHING TO REPAIR THE LIGHT.

Mileage: 154,000

SOMETIMES MY LEFT FRONT HEADLIGHT WORKS AND SOMETIMES IT DOESN'T. I HAVE NOT BEEN ABLE TO IDENTIFY ANY CONSISTENT CAUSE OF THE INTERMITTENT FAILURE. SOMETIMES IF THE LEFT HEADLIGHT IS OUT AND I FLICK THE HIGH BEAMS ON AND OFF, THEN THE LIGHT WORKS AGAIN, BUT THIS DOESN'T ALWAYS SEEM TO FIX THE PROBLEM.

Mileage: 125,000

WHILE DRIVING AT NIGHT, MY HEADLIGHTS WILL TURN OFF RANDOMLY. SOMETIMES, IT IS JUST ONE BUT OFTEN IT IS BOTH. IF I TURN THE HEADLIGHTS SWITCH TO OFF AND BACK TO ON, SOMETIMES ONE OR BOTH LIGHTS WILL TURN BACK ON. MORE RECENTLY, THIS TRICK HASN'T BEEN WORKING AS WELL AND I HAVE TO DRIVE JUST USING MY FOG LIGHTS. IT SEEMS TO BE SOMETHING WITH THE COMPUTER THAT CONTROLS THE HEADLIGHTS. IF IT WAS THE BULB IT WOULD ALWAYS BE OUT. IF IT WERE THE WIRING, SIMPLY FLIPPING THE SWITCH ON/OFF WOULDN'T SUDDENLY GET THE WIRING TO CONNECT AGAIN.

Mileage: 45

SPEEDOMETER & OTHER CONTROL INFORMATION DISPLAY WENT BLANK. PULLED OVER TO SIDE OF ROAD BUT UNABLE TO TURN OFF ENGINE. CONTACTED TOYOTA & WAS TOLD PROBLEM IS KNOWN & WARRANTY EXTEND TO 9 YEARS & UNLIMITED MILES. HOWEVER, MY VEHICLE IS OLDER THAN NINE YEARS, SO I MUST PAY ESTIMATE $1400 TO FIX & CAR WILL BE UNAVAILABLE FOR ESTIMATE 2 WEEKS. THE VEHICLE IS UNSAFE TO DRIVE, PRIOR TO THIS KNOWN PROBLEM OCCURRING CAR WAS OPERATING PERFECTLY ( AVERAGING 50 MPG PER TANK OF GAS, DOCUMENTED). THIS APPEARS TO BE A SAFETY PROBLEM THAT WAS KNOWN BY THE MANUFACTURER, HOWEVER THEY SEEMS TO BE TRYING TO HIDE THIS BY MAKING THE STATISTICAL ESTIMATE THAT BY EXTENDING THE WARRANTY THE MAJORITY OF THESE CARS WOULD BE OFF THE ROAD AND THEIR LAWYERS & LEGAL INSURANCE WOULD COST LESS THAN THE FEW HUMANS KILLS AFTER THIS ARBITRARY 9 YEAR RISK PERIOD. I COULD HAVE BEEN KILLED AS A RESULT OF THIS FAILURE! FORTUNATELY I WAS NOT, HOWEVER I AM LEFT WITH A VEHICLE THAT IS UNDRIVEABLE (WITH NO WARNING!) AND CAN ONLY BE REPAIRED BY TOYOTA AT A COST I AM NOT ABLE TO AFFORD!

PASSENGER SIDE HEADLIGHT BEGAN TO TURN OFF INTERMITTENTLY AND HAS CONTINUED SINCE.

HEADLAMP FAILS INTERMITTENTLY. USUALLY CORRECTED BY SWITCHING THE HEADLIGHT SWITCH OFF AND THEN BACK ON. SOMETIMES THIS DOES NOT CORRECT THE PROBLEM.

LEFT HEADLIGHT TURNED OFF INTERMITTENTLY. IF I TURNED THE LIGHT OFF AND BACK ON THE HEADLIGHT WOULD BRIEFLY WORK BUT THEN TURN OFF AGAIN. *TR

Mileage: 260,000

THE RIGHT HEADLIGHT KEEPS GOING OUT AND AFTER WE TURN THE SWITCH BACK AND FORTH IT GOES BACK ON. THIS PAST WEEKEND IN A DRIVING RAIN STORM AT NIGHT, THE LIGHTS WENT COMPLETELY OUT ON A WINDY MOUNTAIN ROAD. I FLICKED THEM ON AND OFF SEVERAL TIMES AND THEY WOULD GO ON AND THEN GO OUT SHORTLY AFTERWARDS. NEITHER DIM OR BRIGHT WOULD WORK. I ENDED UP HAVING TO PULL THE BRIGHT SIGNAL ON THE COLUMN BACK MANUALLY AND HOLD IT WHILE DRIVING THE LAST 45 MINUTES TO HOME. IT WAS VERY DANGEROUS FOR ABOUT 20 MILES IN THE RAIN AT NIGHT THE LIGHTS GOING IN AND OUT ON CURVES OR AGAINST ON COMING TRAFFIC, A HEAD-ON COULD HAVE OCCURRED EASILY. *TR

Mileage: 155,000

BOTH HEADLIGHTS SPONTANEOUSLY WENT OUT AT THE SAME TIME WHILE DRIVING. THIS HAS BEEN AN INTERMITTENT PROBLEM SINCE THAT DATE, DESPITE CHANGING THE BULBS. SOMETIMES THE LIGHTS CAN BE RELIT BY TURNING THE HEADLIGHT SWITCH OFF AND BACK ON. SOMETIMES THIS DOES NOT WORK. PARTICULARLY IF THE BRIGHT LIGHTS ARE ON, THE OFF-ON SWITCHING DOES NOT WORK AND THE HEADLIGHTS REMAIN OFF. *TR

Mileage: 90,000

A DRIVER IN FRONT OF ME TOLD ME ABOUT ONE WEEK AGO THAT MY HEADLIGHTS WERE GOING ON AND OFF WHILE I WAS DRIVING. THEN YESTERDAY WHILE STOPPED AT A TRAFFIC LIGHT, ANOTHER DRIVER GOT OUT OF HIS CAR TO TELL ME THAT MY LIGHTS HAD GONE OFF. I HADN'T NOTICED A CHANGE MYSELF, BUT THEN I PULLED INTO A PARKING LOT AND CUT MY LIGHTS ALL THE WAY OFF AND CUT THEM BACK ON AND THEN THE LIGHT WAS MUCH BRIGHTER. THIS IS NOT A CONSISTENT PROBLEM. SOMETIMES THE LIGHTS STAY ON FINE AND THEN THEY GO OUT RANDOMLY. THERE DOESN'T SEEM TO BE A PATTERN TO WHEN THIS IS HAPPENING. BUT IF I CUT THE LIGHTS OFF AND THEN BACK ON, THE PROBLEM WILL FIX TEMPORARILY. I HAVE SEEN ON SEVERAL FORMS THAT MANY PEOPLE WITH 2004-2006 PRIUSES ARE HAVING THIS PROBLEM. *TR

STARTING LAST YEAR MY PASSENGER SIDE HEADLIGHT INTERMITTENTLY TURNS OFF AND WILL TURN BACK ON ONCE I TURN LIGHTS OFF AND ON. PASSENGER SIDE LIGHT CONTINUES TO PERIODICALLY SHUT OFF FOR NO SPECIFIC REASON THROUGHOUT THE DURATION OF THE TRIP. THIS ISSUE HAS CAUSED NUMEROUS LIGHTING SAFETY ISSUES AS WELL AS INSTANCES OF BEING PULLED OVER FOR HEADLIGHT BEING OUT. AFTER EXTENSIVE RESEARCH ON INTERNET I HAVE DISCOVERED THAT THIS IS A VERY COMMON ISSUE THAT TOYOTA HAS FAILED TO ADDRESS. I PETITION FOR THE NHTSA TO PLEASE LOOK INTO THE ISSUE DESCRIBED ABOVE. I SEEK A FAVORABLE AND JUST DECISION IN REGARDS TO URGING TOYOTA TO DO THE RIGHT THING AND ADDRESS THE POPULAR DEFECT IN NOT ONLY.2004 MODELS BUT SEVERAL OTHER PRIUS MODEL YEARS. TOYOTA HAS PREVIOUSLY ISSUED A RECALL FOR 2006-2009 TOYOTA PRIUS'. THIS PRECEDENCE INDICATES THAT TOYOTA IS WELL AWARE OF THIS PROBLEM AND HAS NEGLECTED TO TAKE ACCOUNTABILITY AND ACTION IN ESTABLISHING A RECALL. *TR

Mileage: 85,000

I PURCHASED THIS VEHICLE IN DECEMBER 2012. EVER SINCE I HAVE HAD THIS PRIUS, I HAVE HAD ISSUES WITH THE FRONT DRIVERS SIDE HEADLIGHT TURNING OFF RANDOMLY. WHENEVER I TURN THE CAR ON, BOTH HEADLIGHTS ARE ALWAYS ON, BUT WHILE DRIVING, THE DRIVERS SIDE HEADLIGHT TURNS OFF. I TOOK IT TO CARFIX IN GARNER, NC AND THEY THOUGHT THAT IT COULD BE THE HEADLIGHT, SO THEY RECOMMENDED CHANGING IT. I ENDED UP HAVING IT CHANGED BY A FAMILY FRIEND BECAUSE IT WAS CHEAPER TO DO IT THAT WAY. THE HEADLIGHT WAS STILL GIVING ME PROBLEMS AFTER BEING CHANGED, SO I TOOK IT TO THE LEITH TOYOTA DEALERSHIP IN RALEIGH, NC AND THEY SAID THAT THE HEADLIGHT THAT I PURCHASED FROM AUTOZONE WAS NOT THE CORRECT TYPE OF HEADLIGHT, SO THEY CHANGED IT AGAIN. EVEN AFTER THEY CHANGED IT, THE HEADLIGHT WAS STILL GOING ON AND OFF RANDOMLY. I TOOK IT BACK TO THE TOYOTA DEALERSHIP TODAY AND THEY SAID THAT IT SOUNDS LIKE SOME KIND OF WIRING ISSUE. I HAVE DONE SOME RESEARCH ON THE ISSUE AND HAVE SEEN RECALLS FOR 2005-2009 PRIUS' FOR THE SAME ISSUES, BUT SINCE MINE IS A 2004 IT DOES NOT FALL INTO THE RECALL CATEGORY. I BELIEVE THAT IT SHOULD BASED ON MY ISSUE COMPARED TO THAT AS WELL AS THE NUMBER OF OTHER COMPLAINTS ON THE INTERNET AND BLOGS THAT I HAVE FOUND. *TR

Mileage: 121,000

WHILE DRIVING ON THE INTERSTATE AT NIGHT, BOTH HEADLIGHTS SUDDENLY WENT OUT. NEITHER THE HIGH BEAMS NOR THE LOW BEAMS WORKED. I HAD TO PULL OVER, AND TURN THE CAR OFF. WHEN I TURNED THE CAR BACK ON, BOTH HEADLIGHTS WORKED FINE. THIS INCIDENT OCCURRED ABOUT 4 WEEKS AGO, AND I TOOK IT TO THE DEALERSHIP. THE DEALERSHIP COULD NOT FIND A CAUSE, AND I DON'T THINK THAT THEY BELIEVED ME. I HAD NO PROBLEMS WITH THE HEADLIGHTS FOR ALMOST 4 WEEKS. THEN 3 DAYS AGO, THE EXACT SAME THING HAPPENED AGAIN. I WAS DRIVING ON THE INTERSTATE AT NIGHT AND BOTH HEADLIGHTS SUDDENLY WENT OUT. AGAIN, I PULLED OVER. WHEN I TURNED THE CAR OFF AND BACK ON, THEY WORKED FINE. THIS IS EXTREMELY DANGEROUS AND FRIGHTENING. I HAVE CALLED TWO DEALERSHIPS AND NEITHER OF THEM HAVE HEARD OF SUCH A THING. HOWEVER, IN RESEARCHING THE INTERNET, I EASILY FIND THAT THIS HAS BEEN THE SUBJECT OF A CLASS ACTION LAWSUIT INVOLVING PRIUS MODEL YEARS 2006-2009. SO THERE SHOULD BE INFORMATION OUT THERE THAT TOYOTA SHOULD BE TELLING THEIR DEALERS. I DON'T KNOW IF IT'S AN ELECTRICAL OR COMPUTER PROBLEM. *TR

Mileage: 292,000

PROBLEM STARTED WITH THE RIGHT HEADLIGHT TURNING OFF INTERMITTENTLY. I REPORTED THE PROBLEM TO THE LOCAL DEALERSHIP ON 8/27/2013 WHEN THE VEHICLE WAS SERVICED. THE DEALERSHIP INDICATED THAT THEY COULD NOT FIND A PROBLEM BECAUSE THE PROBLEM COULD NOT BE DUPLICATED. THEN THE SAME THING STARTED HAPPENING WITH THE LEFT HEADLIGHT. I CAN CORRECT THE PROBLEM BY TURNING OFF & THEN BACK ON THE LIGHT SWITCH BUT THIS CORRECTION DOES NOT LAST LONG AND THE PROBLEM RECURS. I HAVE RESORTED TO DRIVING WITH MY FOG LIGHTS ALSO TURNED ON IN ORDER TO PROVIDE SOME SEMBLANCE OF LIGHT. IT IS DIFFICULT AND DANGEROUS TO DRIVE LIKE THIS IN THE LONG ALASKAN WINTERS WITH SO MUCH ICE AND SNOW ON THE ROADWAYS. I CAN ALSO MAKE THIS PROBLEM OCCUR WHEN WARMING UP MY CAR IN THE DRIVEWAY. *TR

PASSENGER HEADLAMP GOES OUT WHILE CAR IS BEING DRIVEN. DRIVER SIDE HEADLAMP REMAINS ON (ILLUMINATED). TURNING HEADLAMP SWITCH OFF AND ON CAUSES PASSENGER AND DRIVER SIDE HEADLAMP TO ILLUMINATE. ON RE-ILLUMINATION, PASSENGER SIDE HEADLAMP SOMETIMES APPEARS NORMAL AND AT OTHER TIMES APPEARS TO BE DIMMER, MORE YELLOWISH. DEALER QUOTED REPLACEMENT HID BULB AND LABOR TO REPLACE WILL COST $225.00 TOTAL. *TR

MY 2004 TOYOTA PRIUS'S HID LIGHTS ARE GOING OFF INTERMITTENTLY AND COMING BACK ON WHEN I TURNED THEM OFF AND BACK ON AGAIN. THE DRIVER'S SIDE IS GOING OFF AGAIN AND WILL COME BACK ON AGAIN WHEN I TURN IT OFF AND THEN BACK ON. ALSO, MY HEADLIGHT LEVELING SYSTEM WARNING LIGHT IS COMING ON. WHEN I DRIVE ON THE HIGHWAY LIGHT GOES OFF, I FEEL VERY UNSAFE. I HAVE TO TURN THEM OFF AND BACK ON IN SECONDS TO AVOID A POSSIBLE ACCIDENT. DEALER CAN'T FIND THE ISSUE. THEY RECOMMEND TO CHANGE THE BULBS BUT IT DOESN'T SOLVE PROBLEM. *TT

HEADLIGHTS (HID) INTERMITTENTLY GO OUT REGARDLESS OF SPEED OR ROAD CONDITIONS. TURNING THE LIGHT SWITCH THEY COME ON AGAIN AND IT RANDOMLY OCCURS MAKING DRIVING DANGEROUS.

BOTH HEADLAMPS GO OFF AND ON SPORADICALLY, AS FOLLOWS: APPROXIMATELY THIRTY (30) DAYS AFTER BUYING THIS USED CAR, THE LEFT HID HEADLAMP APPEARED BURNT OUT. BOTH LEFT AND RIGHT HEADLAMPS WERE REPLACED ON OR ABOUT JANUARY 8, 2013, AS RECOMMENDED FOR THIS TYPE OF LIGHT. ON INSTALLATION, EITHER LIGHT WOULD FLASH ON BUT THEN GO OUT AGAIN, BUT TURNING THE HEADLAMP SWITCH OFF THEN ON AGAN SEEMED TO RECTIFY THE PROBLEM. BOTH HEADLAMPS THEN REMAINED ON FOR APPROXIMATELY TWO WEEKS, AT WHICH POINT THE LEFT HEADLAMP WAS SPORADICALLY OUT FOR APPROXIMATELY TWO WEEKS, WHEN IT WOULD GO ON ONLY IF THE HEADLAMP SWITCH WERE TURNED OFF THEM BACK ON AGAIN. BOTH HEADLAMPS THEN WORKED FOR APPROXIMATELY SIX WEEKS, AT WHICH POINT THE LEFT HEADLAMP WENT OUT FOR APPROXIMATELY FOUR WEEKS, BUT THEN CAME ON AFTER APPROXIMATELY ONE MONTH WHEN THE POLICE FOUND THE RIGHT LIGHT TO BE OUT. THEY SAID IT NEEDED TO BE FIXED; THAT IT IS A SAFETY HAZARD, AT WHICH I EXPLAINED THE HISTORY OF TOYOTA PRIUS HEADLAMP ISSUES AND THAT I WOULD PURSUE AN APPROPRIATE REMEDY FOR THIS MANUFACTURING DEFECT. THE RIGHT HEADLAMP REMAINS OUT TO THIS DATE, BUT DID COME ON FOR APPROXIMATELY ONE WEEK IN THE INTERIM. TURNING THE HEADLAMP SWITCH OFF THEN ON AGAIN HAS NOT HELPED SINCE THE DAY OF INSTALLATION. *TR

RECENTLY, VEHICLE HAS STARTED INTERMITTENT OUTAGES OF HID HEADLAMPS. USUALLY ON THE DRIVER SIDE, BUT SOMETIMES ON THE PASSENGER SIDE. APPARENTLY THIS IS THE RESULT OF A COMPUTER CALLED THE HID BALLAST OR SOMETHING. TOYOTA IS QUOTING OUTRAGEOUS SUMS TO FIX THE PROBLEM. THIS VEHICLE SHOULD BE RECALLED AND THE PROBLEM FIXED FOR FREE. *TR

A COUPLE OF MONTH AGO, I THOUGHT I NOTICED THAT THE FRONT DRIVERS SIDE HID HEADLIGHT WAS OFF WHEN THE PASSENGER SIDE WAS ON. I WAS DRIVING IN MY OTHER CAR WHILE A FAMILY MEMBER WAS DRIVING THE PRIUS. WHEN I LOOKED AT THE PRIUS A SHORT TIME LATER, BOTH LIGHT WHERE ON. OVER THE PAST COUPLE OF MONTHS I HAVE NOTICED THAT THE DRIVER SIDE HEADLIGHT HAS BEEN INTERMITTENTLY OFF WHEN IT SHOULD BE ONE. CYCLING THE LIGHTS OFF THEN ON APPEARS TO TURN BOTH HEADLAMPS ON FOR SOME PERIOD OF TIME. THERE IS NO INDICATION IN THE CAR WHEN THE FAILURE OCCURS, AND I AM CONCERNED THAT THIS CREATES AN UNSAFE SITUATION WHILE DRIVING AT NIGHT. WHILE TRYING TO DETERMINE IF THIS IS A KNOWN PROBLEM, I CAME ACROSS OWNER CHAT GROUPS WHERE OTHERS WHERE COMPLAINING ABOUT THE SAME PROBLEM. I ALSO READ THAT THERE MIGHT BE AN NHTSA INVESTIGATION INTO SIMILAR COMPLAINTS. I WOULD LIKE TO KNOW IF AN INVESTIGATION HAS HAPPENED AND IF SO, WHAT WAS THE OUTCOME? *TR

WHILE DRIVING MY 2004 TOYOTA PRIUS HOME AT NIGHT ON A DARK, WINDING ROAD, BOTH HEADLIGHTS SUDDENLY WENT OUT!!!! THERE WAS NO LIGHT! PITCH BLACK! CRAZY! I COULDN'T BELIEVE THAT MY LIGHTS WERE OUT. MY BRIGHTS WERE NOT WORKING EITHER. I DIDN'T KNOW WHAT HAPPENED TO THE CAR! I THOUGHT I WAS GOING TO WRECK/CRASH. I WAS ABOUT 18 MILES FROM HOME. AS I DROVE, I TURNED ON MY DOME LIGHTS SO THE ONCOMING TRAFFIC COULD SEE ME. AFTER TURNING THE CAR LIGHTS ON AND OFF, THEY CAME BACK ON, BUT WHAT A NIGHTMARE!!!!! I FOUND OUT THAT OTHER TOYOTA PRIUS OWNERS HAD THE SAME PROBLEM WITH THERE CARS. TOYOTA NEEDS TO FIX THIS PROBLEM!!!!!!!!!!!!!! TOYOTA NEEDS TO RECALL AND REPLACE THESE FAULTY HEADLIGHTS! *TR

2004 TOYOTA PRIUS WITH HID HEADLIGHTS IS USED AS A TAXI CAB. ON SEPTEMBER 25TH, 2012 THE DRIVERS SIDE HEADLIGHT WOULD BEGIN TO FLICKER AND TURN OFF AFTER AROUND FIVE MINUTES OF OPERATION. THE HID BULB REPLACEMENT DID NOT RESOLVE THE MATTER. HEADLIGHTS MUST BE TURNED OFF AND THEN ON AGAIN IN ORDER TO RESUME THEIR OPERATION. *TR

TL* THE CONTACT OWNS A 2004 TOYOTA PRIUS. THE CONTACT STATED THAT THE HIGH INTENSITY DISCHARGE (HID) HEADLIGHTS WOULD INTERMITTENTLY FAIL. THE FAILURE RECURRED FOR APPROXIMATELY ONE YEAR. THE VEHICLE WAS TAKEN TO A DEALER WHERE THEY ADVISED THE CONTACT THAT THE BALANCES ON THE FRONT HEADLIGHTS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE AND THE CURRENT MILEAGE WAS UNKNOWN. THE VIN WAS UNAVAILABLE.

THE PASSENGER HEADLIGHT AND TAILLIGHT STOPPED WORKING. WE REPLACED THE TAIL LIGHT BULB ONLY FOR IT TO STOP WORKING TWO DAYS LATER. WE REPLACED THE TAIL LIGHT BULB ONCE A WEEK FOR A MONTH, AND FOR NOW IT CONTINUES TO WORK. THE HEADLIGHT, HOWEVER, CONTINUED NOT WORKING FOR ABOUT TWO WEEKS, THEN BEGAN WORKING AGAIN ONLY FOR THE DRIVER SIDE HEADLIGHT TO STOP WORKING. AFTER TURNING THE HEADLIGHT SWITCH OFF THEN BACK ON BOTH HEADLIGHTS BEGAN WORKING. HOWEVER, AFTER 10 MINUTES BOTH WENT OUT AGAIN. EVER SINCE THEN, IT IS ALWAYS A GUESS AS TO WHICH HEADLIGHT, IF ANY, WILL WORK AT DUSK. SOMETIMES THEY WILL BOTH WORK FOR ABOUT A WEEK BEFORE QUITTING. I WAS GIVEN AN ODI# OF 10453541. *JS

INTERMITTENT HEADLIGHT PROBLEM. I PURCHASED THE CAR WITH 111,500 MILES ON IT, AND ALMOST IMMEDIATELY NOTICED THAT THE PASSENGER'S SIDE HEADLIGHT IS INTERMITTENT WHEN VIEWING MY REFLECTION IN THE BUMPER OF THE CAR IN FRONT OF ME. SOMETIMES IT RUNS FINE FOR OVER AN HOUR, OTHER TIMES IT DOESN'T LAST 5 MINUTES. TURNING THE HEADLIGHTS OFF, AND IMMEDIATELY BACK ON RELIGHTS THE HEADLIGHT. THIS IS NOT ONLY HAPPENING AT NIGHT, BUT ALSO DURING THE DAY WHEN THEY ARE USED AS DAYTIME RUNNING LIGHTS. I MADE A VIDEO OF IT HAPPENING: HTTP://TINYURL.COM/INTERMITTENTPRIUSHID I AM NOT THE ONLY PERSON HAVING THIS PROBLEM WITH THEIR PRIUS. OTHERS HAVE REPORTED THIS PROBLEM WITH 25,000 TO 40,000 MILES. IT IS VERY HARD TO NOTICE BECAUSE THE HID HEADLIGHTS ARE SO BRIGHT IT IS HARD TO TELL WHEN ONE IS NOT WORKING, WHICH ACTUALLY MEANS THIS PROBLEM MAY HAVE EXISTED ON MY PRIUS FOR A LONG TIME WITHOUT THE PREVIOUS OWNER NOTICING. TO ILLUSTRATE MY POINT, THIS PRIUSCHAT THREAD HAS OVER 870 RESPONSES TO DATE REGARDING THIS HID HEADLIGHT PROBLEM: HTTP://PRIUSCHAT.COM/FORUMS/GEN-II-PRIUS-CARE-MAINTENANCE-TROUBLESHOOTING/34584-HEADLIGHT-PROBLEM-17.HTML THUS FAR I HAVE NOT NOTICED THIS PROBLEM IN MY DRIVER'S SIDE.

THE DRIVER'S SIDE HEADLIGHT WENT OUT WHILE DRIVING AT HIGHWAY SPEED. TURNING THE LIGHTS OFF AND THEN ON RESTORED THE HEADLIGHTS. IT HAPPENED A COUPLE TIMES IN 2 HOURS OF DRIVING. AT THE END OF THE TRIP IT WAS HAPPENING ABOUT EVERY MILE. I TOOK THE CAR TO THE TOYOTA DEALERSHIP AND THEY REPLACED THE DRIVER'S SIDE LAMP. LAST NIGHT 1/2 HOUR INTO A 2 HOUR NIGHT TRIP THE HEADLIGHTS WENT OUT. IT APPEARED THAT BOTH LIGHTS WENT OUT THIS TIME. THE LIGHTS WENT OUT EVERY 30 SECONDS THEREAFTER. UPON ARRIVING AT THE DESTINATION, I LEFT THE CAR RUNNING AND CHECKED OUT THE LIGHT SITUATION. THE DRIVER'S SIDE HEADLIGHT WOULD GO OUT AND THE PASSENGER SIDE APPEARED TO DIM. THE RUNNING LIGHTS REMAINED ON. IT APPEARS THAT OTHER PRIUS OWNERS HAVE EXPERIENCED SIMILAR PROBLEMS. IT ALSO SEEMS THAT REPLACING THE LAMP IS NOT THE SOLUTION TO THE PROBLEM. IT MAY BE AN ELECTRICAL OR COMPUTER PROBLEM. I SHALL TAKE THE CAR BACK TO THE DEALERSHIP NEXT WEEK. THIS IS A SAFETY ISSUE DURING NIGHT DRIVING. *TR

HID HEADLIGHTS GO OFF INTERMITTENTLY WHILE DRIVING. HEADLIGHTS CAN BE RESET BY TURNING HEADLIGHT SWITCH TO OFF AND BACK ON AGAIN. A SEARCH OF THE NHTSA AND OTHER WEBSITES DEMONSTRATE THAT THIS SAME PROBLEM IS WIDESPREAD FOR SEVERAL YEAR MODELS OF PRIUS AUTOS. THE DEALER ESTIMATES TO REPLACE THE HEADLIGHT BULBS IS ABOUT $1000 PER HEADLIGHT, MAKING THIS A SERIOUS PROBLEM BECAUSE PEOPLE WILL SEEK LOWER COST REMEDIES WHICH ARE NOT SAFE. TOYOTA THUS FAR HAS NOT OFFICIALLY RECOGNIZED OR ATTEMPTED TO ADDRESS THIS ISSUE. SINCE A TOTAL LOSS OF LIGHTING CAN OCCUR AT ANYTIME WITH SERIOUS CONSEQUENCES, A RECALL SHOULD BE PERFORMED TO CORRECT THIS ISSUE BEFORE FATALITIES OCCUR. *TR

Mileage: 170,000

THE DRIVER'S SIDE HID HEADLIGHT, INTERMITTENTLY, UNPREDICTABLY AND INEXPLICABLY SHUTS OFF. IT WILL OCCASIONALLY RETURN TO SERVICE ON ITS OWN, BUT USUALLY REQUIRES A CYCLING OF THE LIGHT'S POWER SWITCH BEFORE FULL FUNCTION IS RESTORED. AFTER WHICH, THE LENGTH OF TIME BEFORE THE LIGHT SHUTS OFF AGAIN VARIES FROM A FEW SECONDS TO NOT AT ALL. AFTER RESEARCHING THIS ISSUE, IT SEEMS TO BE A RATHER SYSTEMIC PROBLEM WITH THE 2004-2009 PRIUS. OBVIOUSLY, THE SITUATION THIS CONDITION CREATES IS UNSAFE AT BEST, CAN PLACE ME PERSONALLY IN AN UNEXPECTED ILLEGAL POSITION - AND (SHOULD BOTH LIGHTS GO OUT TOGETHER, AS SOME HAVE REPORTED) COULD QUITE POSSIBLY BE LIFE THREATENING. FOR THE SAFETY OF THE DRIVING PUBLIC, I WOULD STRONGLY URGE NHTSA TO INVESTIGATE THIS ISSUE. TOYOTA MUST TAKE RESPONSIBILITY FOR THEIR DESIGN FLAW, AND ENGINEER A RESOLUTION TO THIS PROBLEM. *TT

WHEN I SEE THEY HAVE STOPPED I WILL TURN THE LIGHTS OFF AND BACK ON AND THEY WORK AND WILL USUALLY STAY WORKING THE REST OF THE TRIP, BUT NOT ALWAYS. I HAVE BEEN LOOKING ONLINE AND THIS SEEMS TO BE A COMMON PROBLEM. I WAS JUST AT MY TOYOTA DEALER AND THEY SAID IT IS PROBABLY THE BULB AND THEN UNDER HIS BREATH HE UNOFFICIALLY SAID IT IS A CRAP SHOOT FOR SOLVING THE PROBLEM. *TR

HEADLIGHTS WOULD GO OUT, BUT COME BACK ON. AT FIRST, IT WAS ONLY ONE HEADLIGHT, BUT ONE EVENING, WHEN ONE HEADLIGHT WENT OUT, I SWITCHED TO HIGH BEAMS AND BOTH WENT OUT.

MAJOR PROBLEM WITH THE VEHICLE'S HEADLIGHTS. THEY INTERMITTENTLY TURN THEMSELVES OFF WITHOUT ANY WARNING. TRIED REPLACING THEM PER THE MANUAL INSTRUCTIONS BUT THE INSTALLED LAMPS ARE DIFFERENT THAN THE MANUAL, SO REPLACING THEM IS NOT AN OPTION. I CONSIDER THIS A MAJOR SAFETY DEFECT. THESE LAMPS ARE SUPPOSED TO LAST THE LIFE OF THE CAR. ANY HEADLAMP THAT STOPS WORKING WITHOUT WARNING IS A SAFETY ISSUE. I HAVE NEVER HEARD OF THIS HAPPENING BEFORE WITH ANY CAR. YOU CAN MAKE THE LIGHT COME BACK ON BY TURNING ALL THE LIGHTS OFF AND THEN ON AGAIN. THIS DEFECT IS GOING TO CAUSE A MAJOR ACCIDENT AND FOLKS ARE GOING TO GET HURT OR WORSE. *TR

MY COMPLAINT HAS TO DO WITH THE HIGH ENERGY DISCHARGE (XENON) HEADLIGHTS ON MY 2004 TOYOTA PRIUS. BEGINNING SOMETIME IN FEBRUARY 2010 MY WIFE AND I BEGAN TO NOTICE THAT THE DRIVERS SIDE HEADLIGHT WOULD SHUT DOWN AFTER THE LIGHTS HAD BEEN ON FOR A FEW MINUTES. IF THE HEADLIGHTS WERE QUICKLY TURNED OFF AND THEN BACK ON (SAY, WHILE STOPPED AT A TRAFFIC LIGHT), BOTH HEADLIGHTS WOULD WORK JUST FINE FOR A WHILE. I TRIED TO REPLACE THE BULBS (D2R TYPE XENON BULBS) WHICH I PURCHASED AT A LOCAL CAR PARTS STORE FOR APPROXIMATELY $90 EACH. AFTER TRYING TO FOLLOW THE INSTRUCTIONS FOR REPLACING THE BULBS (FOUND IN THE OWNERS MANUAL), I WAS UNABLE TO OPEN THE BULB HOLDERS. WHEN I HAD THE CAR AT THE DEALERSHIP (CAPITOL TOYOTA) FOR SERVICE IN LATE APRIL 2010, I ASKED IF THEY COULD FIX THE HEADLIGHTS. THE SERVICE REP TOLD ME THAT MERE DIAGNOSIS OF THE PROBLEM WOULD COST $600, WITH ANY BALLAST OR BULB REPLACEMENT ADDED TO THAT COST. I HAVE NEVER PAID MORE THAN ABOUT $40 TO REPLACE BOTH OF MY VEHICLE HEADLIGHTS PRIOR TO THIS. I APPRECIATE THAT THESE BULBS SHOULD COST MORE THAN HALOGEN OR OTHER TYPES, BUT THE COSTS I'M ENCOUNTERING ARE OUTLANDISH. IN THE MEAN TIME, WE ARE STILL DRIVING THE CAR WITH THE PROBLEM. HEADLIGHTS WORK FOR FIVE TO 10 MINUTES, AND THEN ONE, AND NOW, SOMETIMES THE OTHER HEADLIGHT WILL SHUT DOWN. RECENTLY, OUR DAUGHTER ARRIVED BACK FROM A BRIEF TRIP COMPLAINING THAT THE HEADLIGHTS WERE VERY DIM. I FOUND OUT THAT NEITHER HEADLIGHT WAS WORKING - THE ONLY LIGHTS ON THE FRONT OF THE CAR WERE THE FOG LAMPS. WE NOW DO NOT DRIVE THIS CAR AT NIGHT, AND WONDER HOW WE WILL FIX THIS PROBLEM. *TR

INTERMITTENT HEADLIGHT FAILURE ON MY 2004 TOYOTA PRIUS. IT FIRST HAPPENED AROUND 67,000 MILES WHEN BOTH HEADLIGHTS WENT OUT AT ONCE (AT NIGHT!). FLICKING THE SWITCH DID MAKE THEM COME BACK ON. AFTER THAT, THE FAILURE HAS BEEN INCREASING, MAINLY WITH THE PASSENGER SIDE HEADLIGHT. TURNING THE SWITCH NO LONGER ALWAYS WORKS TO TURN THE LIGHT BACK ON. I CAN;T ALWAYS TELL THAT IT IS OFF IF THEY ARE ON FOR ME TO ME SEEN (SUCH AS IN RAIN) RATHER THAN TO ALLOW ME TO SEE. THIS IS INCREDIBLY DANGEROUS. I CAN;T DRIVE THE CAR AT NIGHT RELIABLY NOW AND WHAT ABOUT IN RAIN (WHICH IS NOT AS EASILY PREDICTABLE AS "DAY/NIGHT")? THIS IS CLEARLY NOT A RARE OCCURRENCE. TOYOTA NEEDS TO STEP UP HERE.

I UNDERSTAND YOU OPENED AN INVESTIGATION ON THIS ISSUE A WHILE AGO BUT THEN CLOSED IT WITHOUT A FINDING OF A SAFETY DEFECT. PLEASE REOPEN IT AGAIN. THERE IS A CONTINUOUSLY GROWING BODY OF REPORTS OF THIS ISSUE WITH THE TOYOTA PRIUS. GO TO WWW.PRIUSCHAT.COM AND SEARCH FOR THE HID HEADLIGHT THREAD TO SEE WHAT I MEAN. MANY OWNERS HAVE HAD TO PAY $500 TO $1000 OUT OF POCKET TO TOYOTA DEALERS TO FIX THIS PROBLEM. IN SOME CASES, THE PROBLEM HAS RECURRED A FEW MONTHS LATER. PLEASE ASK TOYOTA TO ISSUE A SAFETY RECALL OF PRIUS MODELS AFFECTED BY THIS ISSUE. I HOPE YOU CAN GET TOYOTA TO DO THIS BEFORE SOMEONE DIES BECAUSE OF THIS PROBLEM.

LAST FALL THE LEFT HEADLIGHT WAS NOTICED TO BE OUT ON MY 2004 TOYOTA PRIUS BY A NEIGHBOR WHEN I CAME HOME ONE NIGHT IN NOVEMBER, 2009. MADE AN APPOINTMENT TO GET IT FIXED AT MY TOYOTA DEALER, BUT THEN IT CAME ON THE NEXT DAY. WHEN I CANCELED THE APPOINTMENT WITH THE DEALER THEY MENTIONED TO WATCH IT, SINCE THE HEADLIGHTS WERE KNOWN TO GO ON AND OFF. WE LEFT WITHIN THE NEXT COUPLE OF DAYS FOR A VACATION DRIVE FROM MD TO NC. HEADLIGHT STAYED ON UNTIL WE WERE IN NC. WENT TO A TOYOTA DEALER AND WAS TOLD IT WOULD BE $900 TO REPLACE THE HEADLIGHT SINCE THE COMPUTER BEHIND THE LIGHT HAD TO BE REPLACED AS WELL. AT THAT OUTRAGEOUS PRICE - FOR JUST ONE HEADLIGHT - WE DID NOT GET IT FIXED. THE HEADLIGHT THEN STAYED ON MOST OF THE REST OF THE TRIP, BUT PERIODICALLY GOES OFF. THIS IS A SAFETY ISSUE AND IT SHOULD CERTAINLY NOT COST ALMOST A THOUSAND DOLLARS TO FIX A HEADLIGHT. *TR

THIS IS AN UPDATE TO THE COMPLAINT I FILED ON 2008/10/14, ODI 10253642 ABOUT PRIUS HID HEADLIGHT FAILURE. SINCE THAT INCIDENT I HAVE HAD THE DRIVER AND PASSENGER SIDE BULBS REPLACED FOUR TIMES AND SWAPPED LEFT-FOR-RIGHT FOR DIAGNOSIS TWICE. EVEN WITH THOSE NEW BULBS, WHICH MY DUBLIN, CA, TOYOTA DEALER SWEARS ARE THE NEWER, "GOOD" BULBS, THE HEADLIGHTS ALWAYS HAVE FAILED AGAIN WITHIN ONE TO FOUR WEEKS. ACTUALLY, THOSE ARE THE INTERVALS AT WHICH I HAVE *NOTICED* THE FAILURES, BUT I'M SURE THE BULBS FAILED SOONER THAN THAT, BECAUSE SOMETIMES IT'S HARD TO TELL WHILE DRIVING, AND THE LIGHTS ALWAYS RELIGHT WHEN SWITCHED OFF AND ON. THERE WOULD HAVE BEEN EVEN MORE REPLACEMENTS AND FAILURES, BUT I HAVE DELAYED TAKING THE CAR IN FOR REPAIR UNTIL I COULD DRIVE INTO THE DEALERSHIP WHILE THE LIGHT WAS OUT, AS PROOF THAT IT HAS FAILED. IT'S OBVIOUS TO ME AND EVERY OTHER PRIUS OWNER THAT THE BULBS ARE EITHER NOT THE PROBLEM OR AT LEAST NOT THE ONLY PROBLEM--THE ELECTRONIC CONTROL MODULE UNDOUBTEDLY ALSO OR INSTEAD IS FAULTY. TOYOTA CORPORATE CONTINUES TO REFUSE TO ACKNOWLEDGE THE SEVERITY, PERSISTENCE, AND BREADTH OF THE PROBLEM. YESTERDAY THE DEALER REPEATED THE LEFT-FOR-RIGHT SWAP BECAUSE "TOYOTA CORPORATE DEMANDS THAT DIAGNOSTIC PROCEDURE." BUT THE DEALER ADMITTED THAT NO MORE INFORMATION WILL BE GAINED THAN WAS GAINED THE LAST TIME THEY SWAPPED LEFT FOR RIGHT, WHEN THE LIGHT WORKED THERE AT THE DEALER, BUT FAILED ON ME SUBSEQUENTLY (THE SAME-SIDE HEADLIGHT WITH THE SWAPPED BULB). THEY ARE SIMPLY AVOIDING THE EXPENSE AND LIABILITY OF REPLACING THE CONTROL COMPUTER. *TR

DRIVER-SIDE HID HEADLIGHT TURNS ITSELF OFF AT BRIEF INTERVALS. TURNING HEADLIGHT SWITCH OFF AND ON RESTORES IT, WITHOUT FAIL. SITUATION REMAINED STABLE FOR OVER A YEAR, NOV. 2008 TO JAN. 2010.

REPLACING LAMP DID NOT FIX THE PROBLEM -- IN FACT, NEW BULB TURNS OFF MORE THAN ONCE A MINUTE, WHILE OLD BULB TURNED OFF ABOUT EVERY 10 MINUTES. *TR

I TOOK THE CAR TO THE TOYOTA DEALER, WHERE THEY REPLACED THE HEADLIGHTS FOR $990. A FEW WEEKS LATER THE SAME THING HAPPENED, HEADLIGHTS CUT OUT AT NIGHT. I TOOK THE CAR BACK TO THE DEALER, WHERE THEY KEPT IT FOR SEVERAL DAYS. THEY THEN RETURNED THE CAR, ASSURING ME THAT THE PROBLEM WAS SOLVED.

THIS IS A SERIOUS DEFECT! LIGHTS CAN GO OUT AT ANYTIME. WE CURRENTLY DO NOT DRIVE THIS CAR AT NIGHT. THIS HAS BEEN AN ONGOING PROBLEM FOR SEVEN MONTHS. MULTIPLE INTERMITTENT HEADLIGHT FAILURES LEADING UP TO HEADLIGHT REPLACEMENTS FOR PASSENGER AND DRIVERSIDE. THE PASSENGER SIDE FAILED FIRST (01/2009) AND ON AVERAGE WOULD FAIL 1-2 TIMES PER WEEK. DRIVER SIDE FAILED FOR THE FIRST TIME THIS MONTH (01/2010) AND HAS ONLY FAILED ONE TIME TO DATE 01/16/2010. NOW ONE YEAR LATER THE PASSENGER SIDE HAS STATED TO FAIL AGAIN. ALL FAILURES ARE SIMILAR IN NATURE IN THAT THEY WILL COME BACK ON TYPICALLY AFTER THE CAR HAS BEEN TURNED OFF FOR A PERIOD OF TIME. HOWEVER ON OCCASION THEY MAY COME BACK ON BY THEMSELVES. MY BROTHER AND I HAVE REPLACED THE PASSENGER SIDE (2 HOUR PROCESS) AND AM IN THE PROCESS OF PURCHASING TWO NEW BULBS FROM A LOCAL AUTO PARTS STORE. $150 EA VS TOYOTA $325 EA AND DOES NOT INCLUDE INSTALLATION LABOR. THE AVERAGE GUY SHOULD NOT ATTEMPT THIS BULB REPLACEMENT IT IS DIFFICULT. I STILL HAVE THE FACTORY ORIGINAL BULB THAT WE REPLACED.

ABOUT 40% OF THE TIME, MY TOYOTA PRIUS DOESN'T WANT TO STOP OR SLOW DOWN WHEN THE BRAKES ARE APPLIED. UNDER THESE CONDITIONS, I HAVE TO APPLY THE BRAKES HARD AND THEN THE CAR WILL SLOW DOWN.

I WROTE THIS AGENCY A FEW MONTHS AGO REGARDING MY 2004 TOYOTA PRIUS AND THE PROBLEMS I WAS HAVING WITH HEADLIGHTS ALTERNATING ON/OFF. TURNING THE LIGHT SWITCH ON/OFF WOULD TURN IT BACK ON. THREE OR FOUR MONTHS AGO BOTH LIGHTS STARTED GOING OUT AT THE SAME TIME. TURNING THE LIGHT SWITCH ON/OFF INTERMITTENTLY 5-9 TIMES MAKES THEM TURN BACK ON. SO FAR I HAVE HAD THIS HAPPEN TO ME 3 TIMES WITHIN THE LAST WEEK TRAVELING 40-55 MILES AN HOUR. I HAVE JUST READ THAT YOU GUYS STOPPED YOUR INVESTIGATION. HOW MANY ACCIDENTS OR DEATHS DO YOU NEED BEFORE ANYTHING IS DONE ABOUT THIS. WHEN HEADLIGHTS BURN OUT THEY DON'T COME BACK ON. THIS IS OBVIOUSLY AN ELECTRICAL OR COMPUTER GLITCH THAT TOYOTA HAS TO BE AWARE OF. IN ALL MY YEARS OF DRIVING, I HAVE NEVER HAD AN EXPERIENCE AS THAT OF EVERYTHING GOING DARK AND JUST HAVING TO HIT THE BRAKES. LUCKILY WHEN IT HAPPENED LAST NIGHT THE CAR BEHIND US SAW OUR BRAKE LIGHTS AND CAME TO A SAFE STOP. THEY FLASHED THEIR HEADLIGHTS NOT KNOWING WHY OUR CAR WAS STOPPED IN THE MIDDLE OF THE ROAD. I REQUEST A REPLY TO THIS COMPLAINT SINCE NO ONE CONTACTED ME ON MY PRIOR COMPLAINT. THANK YOU. *TR

MY DAUGHTER OWNS A 2004 TOYOTA PRIUS WITH HID HEADLIGHTS. THE LIGHTS FAIL ONE AT ATIME OR BOTH AT THE SAME TIME. THEY COME BACK ON USUALLY BY TURNING THE SWITCH OFF AND THEN BACK ON, EXCEPT WHEN SHE WAS DRIVING AT NIGHT IN THE FOG, AND THEY DID NOT COME BACK ON. SHE HAD TO PARK AND SPEND THE NIGHT BESIDE THE ROAD, UNTIL DAYLIGHT TO CONTINUE DRIVING HOME. SHE HAS CONTACTED TOYOTA ABOUT THE PROBLEM AND HAS FOUND OUT THAT THE BULBS COST $350 A PIECE AND REQUIRES EXTENSIVE DISMANTLING OF THE CAR TO INSTALL THEM. THIS MEANING THAT A $1000 DOLLAR EXPENSE FOR REPLACING THE BULBS, NOT KNOWING IF THERE IS A DEEPER SEATED PROBLEM WITH THE POWER SUPPLY TO THE HEADLIGHTS.

AFTER SEVERAL YEARS OF USE, THE HEADLIGHTS, MOST OFTEN THE RIGHT, BUT SOMETIMES ALSO THE LEFT, SPONTANEOUSLY TURN OFF. THIS HAPPENS ABOUT EVERY 15 MINUTES WHILE DRIVING AT NIGHT.

2004 TOYOTA PRIUS. BOTH HID HEADLIGHTS WILL OCCASIONALLY TURN OFF LIKE THE BULB BURNS OUT, BUT IF YOU TURN OFF THE HEADLIGHTS AND TURN THEM BACK ON IT TURNS ON AGAIN. MOSTLY RIGHT HEADLIGHT, BUT OCCASSIONALLY THE LEFT WILL DO THIS. NOT A LOOSE CONNECTION. ACTS LIKE A RELAY IS TRIPPING ON OVERTEMPERATURE OR OVERCURRENT AND RESETTING ITSELF AFTER THE HEADLIGHTS ARE TURNED OFF. THIS HAS BEEN OCCURRING IN MY CAR SINCE I PURCHASED IT IN MARCH 2007. TOOK IT TO REPAIRMAN, BUT IT WAS GOING TO COST OVER $2000 TO REPLACE A CIRCUIT BOARD AND HEADLIGHT ASSEMBLY. I DON'T HAVE THAT MONEY AND FROM WHAT I'VE READ ON PRIUS OWNERS WEBSITES THIS IS A COMMON ISSUE. *TR

DRIVER SIDE HEADLIGHT GOES OUT INTERMITTENTLY. SOMETIMES TURNING THE CAR OFF AND BACK ON SOLVES IT. NOW, THE PASSENGER SIDE HEADLIGHT IS OUT.

PASSENGER SIDE HEADLIGHT FLICKERS VERY DIMLY. I JUST NOTICED IT TODAY, ON MY MOTHER'S PRIUS. DID SOME RESEARCH, AND WAS AMAZED AT THE COST TO HAVE THE DEALER FIX THIS. IF IT WAS JUST THE COST OF THE BULB ITSELF, I COULD SWALLOW THE RATHER LARGE $130 PRICE (AT KRAGEN) AND DO IT MYSELF, BUT THE NOTES HERE, AND ON MANY OTHER SITES INDICATE THAT BULB REPLACE SOMETIMES FIXES THE PROBLEM (FOR A SHORT PERIOD OF TIME), AND AT OTHER TIMES, IT DOES NOTHING. I WOULD HATE TO THROW $130 DOWN THE TOILET. THE PRIMARY ISSUE THOUGH, IS THAT THE HEADLIGHT GOES DIM/OUT INTERMITTENTLY, WITHOUT WARNING OR PATTERN, AND THERE IS NO WAY TO RELIABLY GET IT RE-LIT. I DON'T FEEL SAVE ASKING MY 69 YEAR OLD MOTHER TO TURN THE HEADLIGHTS ON AND OFF IF IT'S DARK OUT SIDE (AND IF IT'S NOT DARK, HOW WOULD YOU KNOW IT WAS WORKING OR NOT). I AGREE, IT DOES SOUND LIKE A DEFECT AS MANY MANY PEOPLE ARE HAVING THE ISSUE, BUT MORE IMPORTANTLY, A SERIOUS SAFETY ISSUE. HOW LONG MUST WE WANT BEFORE SOME ACTION IS TAKEN BY THE NHTSA? *TR

LEFT HEADLIGHT OF MY TOYOTA PRIUS 2004 WILL TURN OFF WITH NO APPARENT CAUSE, YOU CAN TURN OFF THE LIGHTS AND IMMEDIATELY TURN ON AND IT WILL COME BACK ON AGAIN, THIS ACTION IS DANGEROUS SPECIALLY DRIVING AT NIGHT SINCE YOU?LL HAVE TO BRIEFLY DRIVE WITHOUT THE LIGHTS ON. THIS ISSUE HAS A NON-HARMONIC FREQUENCY BUT IT JUST KEEPS REPEATING, SOMETIMES ON A TRIP FOR 10 MILES IT CAN GO OFF UP TO 5 TIMES AND SOME OTHER TIMES ON THE SAME TRIP IT WILL NOT GO OFF. BY NOW THE FAILURE HASN'T?T BEEN CORRECTED SINCE DEALER WILL CHARGE OVER $1500 TO FIX IT, WHICH I DON'T AGREE TO PAY SINCE THIS IS THEIR FAILURE. *TR

LEFT HEADLIGHT WILL TURN OFF WITH NO APPARENT CAUSE. YOU CAN TURN OFF THE LIGHTS AND IMMEDIATELY TURN ON AND IT WILL COME BACK ON AGAIN. THERE DOESN'T APPEAR TO BE ANYTHING THAT TRIGGERS. DANGEROUS WHEN DRIVING AT NIGHT SINCE YOU HAVE TO BRIEFLY DRIVE WITHOUT THE LIGHTS ON .. TO TURN OFF AND BACK ON AGAIN. WHEN SPOKE TO DEALER ABOUT REPLACING WAS QUOTED $600... "BECAUSE WE HAVE TO REMOVE THE FRONT BUMPER TO GET TO THE HEADLIGHT" (TOYOTA DESIGN FLAW?) BUT THE BULB ITSELF COSTS $400!! THIS FIRST STARTED OCCURRING IN JANUARY 2008 AND WE "LIVED WITH IT" FOR A YEAR BEFORE SPENDING THE $558.15 THAT IT COST TO REPLACE THE ONE BULB IN FEBRUARY 2009. WE WERE PROMPTED TO DO SO ESPECIALLY SINCE OUR DAUGHTER WAS LEARNING TO DRIVE AND WE COULD NOT ALLOW HER TO HAVE TO DEAL WITH THIS SAFETY ISSUE. THE LIGHT IS WORKING PROPERLY NOW, BUT I AM NOT CONVINCED THAT IT WON'T HAPPEN AGAIN ...IF THE BULB WAS THE PROBLEM YOU WOULDN'T THINK TURNING IT OFF AND THEN IMMEDIATELY BACK ON WOULD FIX IT TEMPORARILY. WHEN I SPOKE TO TOYOTA TO COMPLAIN ABOUT THE COST AND APPARENT DEFECT THEY GAVE ME NO INDICATION THAT THIS WAS A REPORTED PROBLEM. SHE MADE IT SEEM LIKE I WAS THE ONLY CASE.. DECEITFUL I THINK. AFTER SEARCHING ONLINE I DISCOVERED ON MY OWN THAT THIS WAS A KNOWN PROBLEM THAT MANY OTHERS HAD. *TR

AFTER 24 HOURS, DEALER AGREED TO REPLACE HEADLAMP AT NO COST. BOTH HEADLAMPS WERE REPLACED AT NO COST TO OWNER. OWNER IS 30 YEAR CUSTOMER OF THIS DEALERSHIP.

BOTH CARS SUFFER FROM INTERMITTENT OPERATION WHICH CAN BE TEMPORARILY RECOVERED BY TURNING THE HEADLIGHT SWITCH OFF THEN BACK ON. ALL TOYOTA WANTS TO DO IS REPLACE BULBS WHEN THE BULB OBVIOUSLY IS NOT THE PROBLEM. I AM SURE THEY ARE BEING DISINGENUOUS WITH CUSTOMERS IN AN ATTEMPT TO POSTPONE THE INEVITABLE.

THIS HAPPENS ALMOST EVERY TIME I DRIVE THE CAR NOW, THE CONSEQUENCES ARE NOT BEING ABLE TO SEE AT NIGHT AND DURING THE DAY SAFETY IS DIMINISHED WITHOUT THE HEADLIGHTS. THE HEADLAMPS WERE REPLACED BUT DID NOT REPAIR THE PROBLEM. THE OLD PARTS ARE NOT AVAILABLE. *TR

ON MY 2004 TOYOTA PRIUS, THE LIGHTS GO OUT RANDOMLY. OF COURSE, AT NIGHT. I TOOK IT TO TWO TOYOTA DEALERSHIPS, AND THE FIRST COULDN'T REPLICATE THE PROBLEM. THE SECOND DEALERSHIP SAID THE FIX FOR ONE LIGHT WOULD BE AN ASTONISHING $850 BECAUSE IT'S A DEFECTIVE ELECTRONIC CONTROLLER. SINCE MY LIGHTS WORKED INTERMITTENTLY OR AFTER BEING TURNED ON AND OFF...AND AFTER SEARCHING THE INTERNET AND DISCOVERING THIS DEFECT IS COMMON. I'M THINKING LIGHTS CUTTING OUT WHILE DRIVING, IS QUITE DANGEROUS, AND IT'S A POTENTIAL HAZARD FOR BOTH DRIVERS AND PEDESTRIANS.

HEADLIGHTS WILL GO OUT INTERMITTENTLY. EITHER SIDE WILL FAIL. IF YOU TURN THE LIGHT SWITCH TO "OFF" AND THEN BACK "ON" THE LIGHTS WILL COME BACK ON. NO PARTICULAR AMOUNT OF ON TIME OR BUMPS IN ROAD CAUSE THE FAILURE. BULBS ARE HID TYPE. DEALER WANTS OVER $630 TO REPLACE BULBS. NON DEALER MECHANIC ADVISED THAT IT MAY BE SOMETHING OTHER THAN THE BULB, POSSIBLY THE HID CONTROLLER. DEALER IS THE ONLY SOURCE AND VERY EXPENSIVE. THIS IS A MAJOR SAFETY ISSUE, THESE ARE THE HEADLIGHTS. THIS FAILURE NOW HAPPENS EVERY TIME THE CAR IS DRIVEN WITH THE HEADLIGHTS ON, VARIES FROM 5 MINUTES TO AN HOUR AFTER THE CAR IS STARTED.

CONTACTED TOYOTA IN FEBRUARY 2009 WITH THE FOLLOWING COMPLAINT/DESCRIPTION: RECENTLY MY DRIVER SIDE HEADLIGHT HAD BEEN BLINKING OFF INTERMITTENTLY WHILE DRIVING. I THEN WOULD HAVE TO TURN THE LIGHTS OFF AND BACK ON TO GET THE LIGHT TO COME BACK ON. LAST NIGHT (FEB. 15TH, 2009), I WAS TAKING MY DAUGHTER BACK TO COLLEGE AND BOTH HEADLIGHTS UNEXPECTEDLY TURNED OFF WHILE DRIVING ON A VERY DARK STRETCH OF HIGHWAY. NEEDLESS TO SAY, THIS WAS VERY UNNERVING. I TRIED TO QUICKLY TURN OFF LIGHTS AND THEN BACK ON. THEY CAME BACK ON ON AFTER A FEW TRIES, BUT THEN THEY DID THE SAME THING TO ME ON MY RETURN BACK TO HOME. THIS WAS A 6 HOUR ROUND TRIP ON A SUNDAY. I DID NOT HAVE ANY RECOURSE BUT TO TRY TO MAKE IT HOME. I FEEL THIS IS AN EXTREME SAFETY ISSUE AND TOOK IT TO THE DEALERSHIP MONDAY. THE DEALERSHIP RAN SOME TESTS AND SAID IT WAS THE HID BULBS AND NOT THE COMPUTER ($375/BULB!!!!!). I THEN VISITED A PRIUS CHAT SITE THAT ANOTHER CUSTOMER TOLD ME ABOUT AS WE WERE WAITING FOR OUR VEHICLES. APPARENTLY THIS PROBLEM IS VERY WIDESPREAD. I AM NOW FORCED TO ONLY BE ABLE TO DRIVE MY PRIUS DURING THE DAY BECAUSE I NEVER EXPECTED A $900 PRICE TAG TO CHANGE OUT THE BULBS ON THE HEADLIGHTS, AND I AM UNABLE TO PAY THAT COST RIGHT NOW. ALSO, I LIVE OFF OF HWY 78 IN SAINT CLAIR COUNTY WHICH IS A VERY CURVY, HILLY RURAL ROAD WITH VERY LITTLE LIGHT. IF THE LIGHTS HAD SPONTANEOUSLY BLINKED OFF ON ME ON THIS ROAD WHEN EITHER I OR ONE OF MY TEENAGERS WERE DRIVING THE VEHICLE, IT COULD HAVE HAD A FAR DIFFERENT RESULT. WILL IT TAKE A DEATH OR INJURY TO INITIATE A RECALL ON THE HEADLIGHTS?

HOWEVER, WHEN I SWITCH HEADLIGHTS OFF AND BACK ON, IT WOULD GO ON, AND STAY ON, FOR COUPLE MINUTES, SOMETIMES HOURS. AFTER THAT IT GOES OFF AGAIN. AT TOYOTA DEALERSHIP THEY TOLD ME THAT COMPUTER WITH THE HEADLIGHT ASSEMBLY MUST BE REPLACED. IT WOULD COST ME AROUND $400. MY CAR IS STILL UNDER WARRANTY, BUT THEY SAID IT DOES NOT COVER IT, EVEN THOUGH AT THE DAY OF THE PURCHASE OF MY CAR, I BOUGHT "BUMPER-TO-BUMPER" ADDITIONAL WARRANTY. WHY THE HEADLIGHTS ARE NOT COVERED REMAINS A MYSTERY. RESEARCH THAT I DID ON THE ISSUE, SHOWED THAT MANY PEOPLE ARE HAVING THE SAME PROBLEM WITH THEIR TOYOTAS AND HAVE NO CHOICE BUT SPEND HUNDREDS OF DOLLARS ON SOMETHING THAT LOOKS LIKE A DEFECT IN THE HEADLIGHT ASSEMBLY.

DRIVER-SIDE HID HEADLAMP IN 2004 TOYOTA PRIUS WAS NOTICED TO BE VERY, VERY, DIM (EFFECTIVELY OFF) AROUND 2008/10/14. TURNING HEADLAMPS OFF AND ON RESTORED BRIGHTNESS. BUT THE PROBLEM RECURRED AT UNPREDICTABLE TIMES--FREQUENTLY ENOUGH TO BE A SERIOUS SAFETY PROBLEM. FREQUENTLY THE DRIVER CAN'T TELL WHILE DRIVING, WHETHER ONE HEADLAMP IS OFF, AND OBVIOUSLY IT'S UNSAFE TO FIX IT BY TURNING IT OFF AND ON WHILE DRIVING. TOYOTA DEALER REPLACED DRIVER-SIDE HEADLAMP ON 2008/10/15, FOR $600! ON 12/15 THE DRIVER NOTICED THE SAME HEADLAMP AGAIN WAS MISBEHAVING IN EXACTLY THE SAME WAY, AND THE PROBLEM HAS RECURRED SINCE THEN AT APPARENTLY RANDOM TIMES. PRIUSCHAT.COM'S MANY POSTERS ABOUT THIS PROBLEM MAKE IT UNLIKELY THAT JUST THE BULB IS THE PROBLEM. PROBABLY THE BALLAST. BUT TOYOTA WON'T COMMENT. I DO STILL HAVE THE ORIGINAL BULB, AND THE BOX FROM THE NEW BULB. LISA AT TOYOTA CORPORATE CUSTOMER EXPERIENCE CENTER REPLIED AROUND 2008/10/18 THAT TOYOTA WOULD REIMBURSE HALF OF THE $600. BUT AS OF 2009/1/3 NO REIMBURSEMENT HAS BEEN GOTTEN. I CALLED TOYOTA CORPORATE AGAIN ON 2008/12/16 AND DAMIAN SAID HE MUST FORWARD MY NEW COMPLAINT ABOUT THE REPEATED FAILURE TO LISA, AND THAT SHE WAS "REQUIRED" TO RESPOND IN ONE BUSINESS DAY. SHE HAS NOT RESPONDED AS OF 2009/1/3. THERE ARE MANY COMPLAINTS ABOUT EXACTLY THIS PROBLEM ON PRIUSCHAT.COM AT HTTP://PRIUSCHAT.COM/FORUMS/CARE-MAINTENANCE-TROUBLESHOOTING/34584-HEADLIGHT-PROBLEM-26.HTML. *TR

RANDOM HEADLIGHT FAILURE. WHEN FOG LIGHTS ARE NOT ON TOTAL FAILURE OF HEADLIGHTS HAS OCCURRED. RIGHT, LEFT OR BOTH HEADLIGHTS WILL GO OUT WITH NO CORRELATION TO WEATHER, SPEED, TEMPERATURE, LOCATION OF LAMP OR TIME OF DAY. QUICKLY TURNING THE LIGHT SWITCH OFF THEN ON WILL REILLUMINATE BOTH LAMPS. THE LAMPS MAY GO OUT AGAIN, STAY LIT, THE SAME LAMP WILL GO OUT OR THE PREVIOUSLY LIT LAMP MAY FAIL AND THE PREVIOUSLY FAILED LAMP MAY LIGHT. THERE IS A REDUCED INTERVAL BETWEEN FAILURES . LIGHTBULB REPLACEMENT HAS BEEN SUGGESTED BUT THIS HAS NOT SOLVED THE PROBLEM FOR SIMILAR COMPLAINTS. *TR

I OWN A 2004 TOYOTA PRIUS. I JUST PAID $332.50 TO HAVE MY 2 HEADLIGHTS' HIB BULBS REPLACED - AND THAT DIDN'T INCLUDE THE PARTS COST BECAUSE I PROVIDED THE HID BULBS FROM AN ONLINE AUTO PARTS SUPPLIER. THE SYMPTOMS WERE THE SAME AS NOTED BY SO MANY OTHER PRIUS OWNERS: FREQUENT LOSS OF LIGHT FROM THE HEADLIGHT, AND RECOVERY BY ROTATING THE LIGHT SWITCH OFF THEN ON AGAIN...ONLY TO HAVE IT RE-OCCUR A FEW MINUTES LATER. EACH HEADLIGHT HAD ITS OWN PATTERN OF INCONSISTENCY, BUT BOTH HAD THE DYSFUNCTION. I HAVE RECEIVED TWO TRAFFIC CITATIONS FOR DRIVING WITH A HEADLIGHT OUT. THE DEALERSHIPS IN GLEN BURNIE, MARYLAND AND IN LAUREL, MARYLAND BOTH QUOTED ME A PRICE FOR ONE HID BULB OF $351.02 I WAS ABLE TO FIND THE EXACT BULB ONLINE AT PARTSQUICK.COM FOR A PRICE OF $57.27 THAT'S RIGHT, THE DEALERSHIP WANTED TO CHARGE ME $293.75 MORE PER BULB. I PURCHASED TWO ONLINE, WHICH - WITH FREE SHIPPING - COST ME $114.54 FOR BOTH. DO THE MATH...FOR TWO LIGHT BULBS ONLY (NOT COUNTING LABOR) ONLINE I SAVED $587.50 HAD I NOT PURCHASED THE BULBS ONLINE, THE TOTAL OUT-OF-POCKET TO REPLACE BOTH HEADLAMP BULBS WOULD HAVE BEEN: $ 702.04 PARTS ($351.02 X 2) $ 332.50 LABOR $1,034.54 TOTAL THE DEALERSHIP TOLD ME THEY COULDN'T GUARANTEE THAT THE BULBS WERE THE PROBLEM, NOR THAT REPLACING THE BULBS WOULD SOLVE THE PROBLEM, BUT THAT TOYOTA INSTRUCTS THEM TO REPLACE THE BULBS FIRST. THIS IS INSANE, AND CERTAINLY UNSAFE. *TR

RIGHT HEADLIGHT INTERMITTENT TOOK IT TO THE DEALER SAID I DON'T HAVE A PROBLEM FUNCTIONS PERFECTLY. WELL I NOW HAVE A TICKET TO PROVE OTHER WISE. TURN THE HEADLIGHTS OFF IT WILL COME ON THEN DIE. NOW THE LIGHT JUST PLAIN DOESN'T WORK. DEALER WANTS $886 TO REPLACE. SOUNDS LIKE A DEALER RECALL PROBLEM WITH A MAJORITY OF PRIUS HID SYSTEMS. IT IS ALSO A SAFETY ISSUE. *TR

RIGHT HEADLIGHT QUIT WORKING I GOT A TICKET OUT OF THE DEAL AND THE TOYOTA DEALER WANTS ALMOST $1000 TO FIX THE PROBLEM. RIDICULOUS THE FRONT BUMPER HAS TO BE REMOVED. MANY OTHERS HAVE HAD THE SAME PROBLEM SOUNDS LIKE A DEALER RECALL TO ME. *TR

I WAS QUOTED $466 JUST FOR THE PRICE OF MY BULB FOR THE HEADLIGHT OF MY TOYOTA PRIUS. FOR A NON LUXURY CAR IT SO EXPENSIVE THAT A LOT OF PEOPLE WILL CHOOSE TO MAKE DUE WITH THEIR FLICKERING ONE. IT IS OUTRAGEOUS THAT TOYOTA DID NOT GIVE A MORE AFFORDABLE CHOICE. IT IS GOING TO BE MORE DANGEROUS OUT THERE. *TR

I HAVE A 2004 PRIUS AND THE FRONT RIGHT HEADLIGHT IS WORKING ONLY INTERMITTENTLY. THIS HAPPENS AT LEAST THREE OR FOUR TIMES A WEEK; I HAVEN'T SEEN ANY PATTERN. I HAD MY DEALER CHECK THE LIGHT AND ITS CONNECTIONS AND I WAS TOLD THAT THE HID LIGHT BULB WAS NOT WORKING AND THAT IT NEEDED TO BE REPLACED AND THAT I COULD ONLY REPLACE THEM AS A PAIR. THE REASON BEING THAT THEY ARE SOMEHOW CONNECTED TO EACH OTHER AND THAT ONE FAILING WOULD LEAD TO THE OTHER FAILING AS WELL. THE COST WAS AN OUTRAGEOUS $452 EACH WITH LABOR AND THAT MY EXTENDED WARRANTY DOESN'T COVER IT! *TR

DRIVER'S SIDE HIGH INTENSITY DISCHARGE HEADLAMP BEGAN SWITCHING OFF ABOUT A MONTH AGO. LAST WEEKEND WHILE TRAVELING AT NIGHT, THE HEADLAMP WENT OUT ABOUT 15 TIMES IN 3 HOURS. EACH TIME TURNING THE HEADLAMP SWITCH OFF AND BACK ON TEMPORARILY SOLVED THE PROBLEM. I BROUGHT THE CAR TO THE DEALER AND THEY REPLACED THE HID BULB FOR $355. I HAD THE SAME PROBLEM WITH THE PASSENGER SIDE HEADLAMP SIX MONTHS AGO AND REPLACING THE BULB HAS SOLVED THE PROBLEM (TO DATE). THIS IS A DISCONCERTING ISSUE. I HAVE NOT RECEIVED AN EXPLANATION AS TO WHY THIS OCCURS AS OPPOSED TO A NORMAL HEADLAMP JUST BURNING OUT AND THEN BEING ABLE TO REPLACE IT FOR TWENTY BUCKS. *TR

TOYOTA 2004 PRIUS - PASSENGER-SIDE HID HEADLIGHT WENT OUT. DEALERS WANT ABOUT $650 TO FIX!!! (INCLUDES HAVING TO TAKE THE BUMPER OFF.) THE COST IS AN OUTRAGE. I CAN'T AFFORD IT. THESE BULBS HAVE APPARENTLY FAILED ON MANY PRIUSES, SO DEALERS ARE CASHING IN. *TR

WHILE DRIVING (OR SITTING IDLING) ONE (OR BOTH) OF THE HEADLIGHTS WILL GO OUT. I HAVE VERIFIED THAT THE LIGHT GOES OUT COMPLETELY AND DOES NOT JUST DIM. WHEN ONLY ONE HEADLIGHT GOES OUT, TURNING THE HEADLIGHT SWITCH OFF THEN BACK ON WILL RE-IGNITE THE HEADLIGHT. WHEN BOTH HEADLIGHTS GO OUT, THEY WILL NOT COME BACK ON BY TURNING THE SWITCH OFF AND ON. IT TAKES 4 OR 5 ATTEMPTS AT SWITCHING OFF/ON BEFORE THEY COME BACK ON. I MUST DRIVE AT NIGHT TIME, AND THIS PROBLEM CAUSES ME TO BE PLUNGED INTO DARKNESS SUDDENLY WHILE DRIVING (A VERY DANGEROUS AND FRIGHTENING EXPERIENCE). THE DEALER DID NOT KNOW THE CAUSE OF THE PROBLEM, BUT WAS VERY WILLING TO SELL ME 2 HEADLIGHT BULBS FOR $790.00 AND IF THAT DID NOT FIX THE PROBLEM, COME BACK AND BUY 2 CONTROL UNITS FOR $950.00. *TR

DRIVER SIDE HID HEADLIGHT GOES OUT, BUT REIGNITES (MOST OF THE TIME) AFTER HEADLIGHT SWITCH IS TURNED OFF AND THEN BACK ON. RECENTLY, THE DRIVERS SIDE LIGHT WAS OUT (AND WOULD NOT REIGNITES), AND THE PASSENGER SIDE LIGHT WENT OUT AS WELL, LEAVING ME WITHOUT HEADLIGHTS. THE PASSENGER SIDE LIGHT DID REIGNITES AFTER TURNING THE SWITCH OFF AND BACK ON. *TR

PASSENGER HEADLIGHT ON 2004 TOYOTA PRIUS GOES OUT INTERMITTENTLY. I HAVE NOTICED THIS ABOUT 8 TIMES. ON ONE OCCASION I WAS IN A VEHICLE IN FRONT OF THE PRIUS AND THE HEADLIGHT WENT OFF AFTER 15 MINUTES OF OPERATION. IT CAME BACK ON AFTER THE VEHICLE WAS TURNED OFF AND RESTARTED. I TOOK IT TO THE DEALER TODAY, EXPECTING A DIAGNOSIS AND THEY PUT IN A NEW HID BULB ($324.00). I HAD THEM SAVE THE OLD BULB BECAUSE I AM DOUBTFUL A NEW BULB WILL SOLVE WHAT APPEARS TO BE AN ELECTRICAL SHORT CIRCUIT PROBLEM. NOT HAVING BOTH HEADLIGHTS OPERATIONAL IS A SAFETY PROBLEM THAT NEEDS TO BE ADDRESSED WITH THE ROOT CAUSE ASCERTAINED AND REPAIRED BY THE MANUFACTURER. *TR

TL*THE CONTACT OWNS A 2004 TOYOTA PRIUS. WHILE DRIVING IN ANY TYPE OF WEATHER, ONE HEADLIGHT WOULD DIM FOLLOWED BY THE OTHER. HOWEVER, BOTH HEADLIGHTS COULD DIM SIMULTANEOUSLY. THE FAILURE OCCURS INTERMITTENTLY. THE VEHICLE'S SPEED WAS NOT A FACTOR. DURING THE FAILURE, ALL OF THE OTHER LIGHTS WERE OPERATIONAL. THE CONTACT HAS HAD THE LIGHTS REPAIRED DUE TO SAFETY CONCERNS. THE CURRENT MILEAGE IS 90,000 AND FAILURE MILEAGE WAS 70,000.

WITH LIGHT BRAKING I CAN STOP MY 2004 PRIUS WITHOUT EVER ILLUMINATING THE BRAKE LIGHTS. THIS RISKS A REAR END COLLISION. THE LIGHTS ILLUMINATE AFTER THE BRAKE PEDAL HAS BEEN DEPRESSED A LITTLE MORE THAN 1/2 INCH. THE SERVICE MANAGER AT MY DEALERSHIP CLAIMED THAT THERE WAS NO ADJUSTMENT AND WOULD NOT TAKE THE CAR INTO THE SHOP. AN INCIDENT DATE, AS REQUIRED ON THIS FORM, IS NOT APPLICABLE. THIS IS HAPPENING EVERY TIME I BRAKE. *TR

TAIL LIGHTS ON MY '04 PRIUS ARE SLOWLY MELTING , AND AS A RESULT, THE DECORATIVE BLACK PLASTIC INSIDE THE ASSEMBLY IS OBSCURING THE BRAKE LIGHTS TO THE POINT THAT THEY ARE BARELY VISIBLE. I WILL NEED TO REPLACE THESE SOON; TOYOTA REFUSES TO DO IT, SAYING I AM OUT OF WARRANTY. *NM

1) ON A 95 DEGREE DAY THE CAR WAS PARKED IN THE SUN. 2) BRAKE LIGHT ASSEMBLY DEFORMED IN THE HEAT OBSCURING SOME OF THE 6 LED REFLECTORS. THE BLACK PLASTIC USED IN THE ASSEMBLY DOES NOT HOLD UP TO THE HEAT. 3) I COMPLAINED TO TOYOTA CORPORATE IN CALIFORNIA TO FIX THE SOURCE OF THE PROBLEM. NOTHING DONE TO DATE.
