2004 Toyota Sienna Lighting Problems

THE HEADLIGHT BULB COMPARTMENT ALLOWS WATER TO LEAK INTO IT ON THE PASSENGER SIDE CAUSING THE BULB TO BLOW. THIS HAS HAPPENED TWICE, THE REPAIR COST WAS $500. WE DROVE THE CAR FOR ONE WEEK AND THE BULB BLEW AGAIN BECAUSE WATER LEAKED INTO THE COMPARTMENT. THIS IS A DESIGN FLAW AND IS HAZARDOUS WHEN YOU ARE DRIVING AT NIGHT OR GOD FORBID IF IT'S RAINING AND DARK. WE ALSO WERE PULLED OVER AND GIVEN A WARNING FROM A STATE TROOPER ABOUT THE BULB BEING OUT. THIS IS A DANGEROUS AND COSTLY SITUATION. WE ARE STILL WAITING TO GET THE BULB REPAIRED A SECOND TIME. IN THE MEANTIME WE ARE WITHOUT A VAN FOR OUR FAMILY. PLEASE DEMAND THAT TOYOTA RECALLS THIS HAZARDOUS DEFECTIVE PART. THE BULB WENT OUT WHILE WE WERE DRIVING AT NIGHT. THIS IS A PROBLEM AND A HAZARD!

TO WHOM IT MAY CONCERN, I PURCHASED A SET OF AFTERMARKET REPLACEMENT HEADLIGHTS FOR MY 2004 TOYOTA SIENNA THAT WERE ADVERTISED AS DOT/SAE APPROVED. HTTP://WWW.AM-AUTOPARTS.COM/2004/TOYOTA/SIENNA/HEADLIGHT-ASSEMBLIES/AM-19245220/350742.HTML BASED ON HOW FAR FROM THE ORIGINAL EQUIPMENT HEADLIGHTS THESE AFTERMARKET LIGHTS PERFORMED (PLUS THE FACT THEY LEAKED) I WENT AHEAD AND RETURNED THEM. FROM MY RESEARCH IT SHOWS THAT THE MAJORITY OF AFTERMARKET LIGHTS DO NOT MEET TITLE 49, PART 571-FEDERAL MOTOR VEHICLE SAFETY STANDARDS, STANDARD NUMBER 108 (FMVSS 108) AND I AM WONDERING WHY THE DOT AND NHTSA IS ALLOWING THEM TO BE SOLD. PLEASE TAKE A LOOK AT THIS STUDY BY A LOBBYING GROUP FOR THESE COMPANIES, WHOSE OWN TEST RESULTS SHOW THEY DON'T MEET THE OEM STANDARDS THAT ARE REQUIRED TO MEET FMVSS 108.

RIGHT PASSENGER HEADLIGHT HAS SOME SORT OF WATER LEAKING INTO THE HEADLIGHT. A SUBSTANTIAL AMOUNT OF MOISTURE ACCUMULATES AND CAN CAUSE ELECTRICAL ISSUES. *TR

THE RIGHT HEADLIGHT IS OUT. WATER, NOT JUST CONDENSATION, IS VISIBLE INSIDE THE ASSEMBLY. ADVICE BEING GIVEN IS THAT I SHOULD REPLACE THE ENTIRE ASSEMBLY (>$900) OR THE REPLACEMENT BULB (~$140) WILL LIKELY JUST BLOW AGAIN BECAUSE OF THE LEAK THAT IS ALLOWING WATER IN THE ASSEMBLY. *JB

CONDENSATION HAD BEEN BUILDING FOR A FEW MONTHS IN THE RIGHT PASSENGER SIDE HID HEADLIGHT, BUT HEADLIGHT WAS STILL OPERATIONAL. THE LOW BEAM HEADLIGHT FAILED IN FEBRUARY AND THE DEALER QUOTED US A PRICE OF $900. FOR THE PARTS ALONE. WHILE DOING RESEARCH ONLINE FOR LESS EXPENSIVE REPAIR OPTIONS, I NOTED MANY COMPLAINTS ABOUT THIS SPECIFIC PROBLEM WITH THIS MODEL YEAR. THIS IS NOT THE ONLY EXPENSIVE DESIGN FLAW WE HAVE ENCOUNTERED WITH THIS VEHICLE (RUN-FLAT TIRES AND NO SPARE). I BELIEVE TOYOTA NEEDS TO STAND BY ITS CUSTOMERS AND OFFER THEM A REASONABLY PRICED SOLUTION FOR THESE SAFETY ISSUES. *TR

DRIVERS SIDE LOW BEAM HEADLIGHT STOP WORKING. REPLACED HID BULB BUT STILL WILL NOT WORK. SWAPPED WITH PASSENGER'S SIDE TO CONFIRM THE BULB IS OK (IT IS). THERE IS A LOT OF CONDENSATION IN THE HEADLIGHT ASSEMBLY (DUE TO THE WEATHER STARTING TO COOL DOWN IN NORTHEAST). AFTER SEEING ALL THE COMPLAINTS ON THIS VERY ISSUE I AM NOW TRYING TO FIGURE OUT A NEXT STEP. THE DEALERSHIP WILL QUOTE ME THE $1K PLUS TO FIX THE HEADLIGHT ASSEMBLY (COMPLAINTS ON THIS ISSUE ARE RAMPANT ON VARIOUS SIENNA FORUMS ON THE INTERNET) SINCE THAT IS THE ROOT CAUSE OF THE PROBLEM. MY WIFE IS UPSET SINCE THIS A MAJOR SAFETY ISSUE IN THE WINTER. I WILL BE CALLING TOYOTA TO UNDERSTAND WHY THEY WILL NOT ACKNOWLEDGE A KNOWN DEFECT IN THE HEADLAMP ASSEMBLY ALLOWING CONDENSATION IN AND THE BULBS TO MALFUNCTION. *TR

TL* THE CONTACT OWNS A 2004 TOYOTA SIENNA. THE CONTACT STATED THAT MOISTURE ACCUMULATED IN THE FRONT PASSENGER'S SIDE HEADLIGHT, REDUCING THE CONTACT'S VISIBILITY OF THE ROADWAY. THE VEHICLE WAS TAKEN TO A DEALER FOR DIAGNOSIS AND THE CONTACT WAS INFORMED THAT THE HEADLIGHT ASSEMBLY WOULD NEED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VIN WAS UNAVAILABLE. THE FAILURE AND CURRENT MILEAGE WAS 100,000.

I NOTICED THAT THE PASSENGER SIDE HEADLIGHT HAS CONDENSATION ON THE INSIDE. I HAVE NOTICED THE LIGHT APPEARS TO BE GIVING OFF LESS LIGHT WHEN DRIVING. WHEN CHECKING FOR A SOLUTION ON INTERNET I SEE MANY PEOPLE HAVE THE SAME PROBLEM. THIS SHOULD BE INVESTIGATED AND A RECALL SHOULD BE DONE AS THIS CAN CAUSE AN SERIOUS AND POTENTIAL ACCIDENT IF THE LIGHT FAILS FROM THE MOISTURE. *TR

TL* THE CONTACT OWNS A 2004 TOYOTA SIENNA. THE CONTACT STATED THAT WATER WAS LEAKING INTO THE PASSENGER SIDE HEADLIGHT. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE, BUT DENIED ANY ASSISTANCE WITH REPAIRS TO THE VEHICLE. THE DEALER WAS NOT CONTACTED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 45,000 AND THE CURRENT MILEAGE WAS 51,000.

2004 TOYOTA SIENNA MOISTURE IN PASSENGER SIDE HEADLIGHT ASSEMBLY DIMINISHES THE BRIGHTNESS OF THE LIGHT AND REDUCES VISIBILITY. TO REPLACE THE ASSEMBLY THE DEALER QUOTED OVER $400. THIS IS APPARENTLY A PROBLEM MANY TOYOTA SIENNA OWNERS HAVE. TOYOTA SHOULD ISSUE A RECALL FOR THIS PROBLEM WHICH IS A SAFETY ISSUE. DRIVING ON DARK, SMALL WINDING ROADS WITH ONE HEADLIGHT NOT GIVING OUT ENOUGH LIGHT IS DANGEROUS. SHAME ON TOYOTA FOR IGNORING THIS PROBLEM! *TR

THE PASSENGER SIDE HEADLIGHT ASSEMBLY ACCUMULATES MOISTURE INSIDE DUE TO THE DESIGN OF THE HEADLIGHT. THE HEADLIGHT WILL SUDDENLY GO OUT WHILE DRIVING. TOYOTA CLAIMS IT IS NOT COVERED UNDER WARRANTY AND HAS AN ESTIMATED REPAIR CHARGE OF $1200 TO REPLACE HEADLIGHT ASSEMBLY. MANY TOYOTA OWNERS HAVE COMPLAINED ABOUT THE FAILURE OF THE HID BULBS THAT ARE BEING USED AND THE DEFECTIVE NATURE OF THE HEADLIGHT ASSEMBLY. ONCE REPAIRED, IT REPORTEDLY KEEPS OCCURRING. MINE WENT OUT WHILE DRIVING IN THE DARK IN THE MOUNTAINS- COULD NOT CONTINUE ON TRIP DUE TO THE HAZARD OF NOT BEING ABLE TO SEE ON THE WINDY DARK ROADS. *TR

PROBLEM WITH CONDENSATION IN THE HEADLIGHTS OF A 2004 TOYOTA SIENNA. PROBLEM FIRST STARTED WITH CONDENSATION ONLY IN PASSENGER SIDE. EVENTUALLY THE LIGHT STOPPED WORKING ALL TOGETHER. SEVERAL DEALERS ATTEMPTED TO RESOLVE THE PROBLEM BY REPLACING BULB, ATTEMPTING TO REPLACE THE ENTIRE HEADLIGHT ASSEMBLY, BUT HAVE NOT BEEN ABLE TO FIX THE PROBLEM. NOW, CONDENSATION HAS APPEARED IN THE DRIVER SIDE HEADLIGHT AND IT TOO HAS STOPPED WORKING. RESEARCH ONLINE INDICATES THAT THIS IS A COMMON PROBLEM AND DEALER WANTING TO REPLACE ENTIRE ASSEMBLY AT A COST OF OVER $1000 PER LIGHT. JUDGING BY THE NUMBER OF COMPLAINTS, THIS IS TRULY A DEFECT AND SHOULD BE CONSIDERED A SAFETY ISSUE. I ALSO SEE COMPLAINTS OF SOMETHING SIMILAR WITH TOYOTA PRIUS. *TR

HEADLAMP ON 2004 TOYOTA SIENNA FAILED INTERMITTENTLY, AND THEN SEEMED TO WORK. EVENTUALLY IT STOPPED WORKING ALTOGETHER. DIAGNOSIS WAS MOISTURE IN THE ASSEMBLY, CAUSING IT TO SHORT OUT. PRICE TO REPAIR? $1700, OF COURSE NOT COVERED BY TOYOTA. APPARENTLY THIS IS A DESIGN FLAW, BASED ON THE NUMBER OF OTHER COMPLAINTS, AND IT'S DEFINITELY A SAFETY CONCERN. *TR

2004 TOYOTA SIENNA, PASSENGER SIDE HEADLIGHT FILLS WITH CONDENSATION MAKING THE HEADLIGHT DIM AND REDUCING VISIBILITY FOR NIGHT-TIME DRIVING, ALSO CAUSING LIGHTBULBS TO FAIL INTERMITTENTLY. TOOK VAN TO DEALER TODAY. THEY QUOTED $445 TO FIX IT. CAME HOME AND FOUND OTHER PEOPLE COMPLAINED OF THE SAME PROBLEM ON THEIR 2004 SIENNA, ALSO ON THE PASSENGER SIDE ONLY. THIS SUGGESTS A DEFECT SINCE IT IS ALWAYS ON THE SAME SIDE OF THE VEHICLE. OTHER OWNERS ALSO REPORTED IMPAIRED NIGHT DRIVING VISIBILITY BECAUSE THE HEADLIGHT IS FOGGED OVER WITH CONDENSATION. *TR

I OWN A 2004 TOYOTA SIENNA WITH 76,000 MILES ON IT. I WAS ONE OF THE FIRST OWNERS WHEN THE NEW MODEL WAS INTRODUCED. IT HAS BEEN WELL MAINTAINED THROUGH MOLLE TOYOTA, KC MO THAT I HAVE BEEN PLEASED WITH PRIOR TO THIS INCIDENT. I HAD SOME PROBLEMS WITH IT INITIALLY AND TOYOTA MOTOR SALES ALWAYS TOOK CARE OF IT AND PROVIDED EXCELLENT SERVICE AND FOLLOW UP. HOWEVER, THE REPUTATION THAT THEY HAVE BUILT OVER THE COURSE OF 4 YEARS HAS COME UNRAVELED. ONE OF MY HEADLIGHTS WENT OUT RECENTLY AND I TOOK IT IN TO THE DEALER TO GET FIXED, ASSUMING IT NEEDED A NEW BULB. I WAS PRESENTED WITH A PROJECTED PRICE OF $ 900.00 TO FIX ONE HEADLIGHT. $ 800.00 OF THIS WAS A ?IGNITER? PART FROM TOYOTA AND $ 100.00 OF THIS WAS LABOR FROM THE DEALER. I FILED A COMPLAINT WITH TOYOTA MOTOR AND IT WAS BOUNCED BACK TO THE DEALER WHO DELIVERED THE MESSAGE THAT THERE WAS NO OTHER OPTION BUT TO PAY THIS, DUE TO THE HIGH MILEAGE. CLEARLY, THIS IS A SAFETY ISSUE AS I CAN NOT AFFORD TO FIX THIS AND CAN NOT DRIVE THE CAR WITHOUT HEADLIGHTS. A REALISTIC REPAIR EXPECTATION WOULD BE TO REPLACE A BULB. THIS IS AN OUTRAGEOUS EXPENSE THAT TOYOTA SHOULD INCUR. THANK YOU, PATRICE LOFQUIST *TR

I HAVE A 2004 TOYOTA SIENNA THAT HAS A LARGE AMOUNT OF CONDENSATION INSIDE OF THE PASSENGER SIDE HEADLIGHT ASSEMBLY. I FIRST NOTICED IT IN DECEMBER WHEN THE CONDENSATION FROZE AND CONSIDERABLY BLOCKED THE HEADLIGHT BEAM. WHEN RESEARCHING ON THE INTERNET TO FIND OUT HOW TO TAKE THE LENS OFF TO DRY THE CONDENSATION I DISCOVERED THAT THE BEAM ASSEMBLY DOES NOT COME APART AND THAT MANY OTHER OWNER'S OF THE SAME MODEL ARE HAVING THE SAME PROBLEM. IN ADDITION, THIS PROBLEM ALWAYS SEEMS TO BE REPORTED ON THE PASSENGER SIDE. EVENTUALLY THE CONDENSATION WILL CAUSE THE LIGHT TO FAIL. TOYOTA REDESIGNED THE SIENNA IN 2004 AND THE NEW, BIGGER HEADLIGHTS WERE A MAJOR CHANGE. THE CONDENSATION SLIGHTLY AFFECTS THE HEADLIGHTS IN THE WARMER MONTHS BUT IS A SIGNIFICANT PROBLEM WHEN THE TEMPERATURES ARE BELOW FREEZING. THIS SEEMS TO BE A DESIGN FLAW AFFECTING VEHICLE SAFETY THAT TOYOTA SHOULD BE REQUIRED TO FIX. *TR

TL*THE CONTACT OWNS A 2004 TOYOTA SIENNA. THE CONTACT STATED THAT THE FRONT PASSENGER SIDE HEADLIGHT COLLECTS CONDENSATION. THE FAILURE HAS BEEN OCCURRING FOR ONE YEAR. HE DISCOVERED THAT MANY OTHER CONSUMERS WERE EXPERIENCING THE SAME ISSUE AND DECIDED TO FILE A REPORT. THE DEALER WAS NOTIFIED AND DISREGARDED THE ISSUE. THE FAILURE MILEAGE WAS 75,000 AND CURRENT MILEAGE WAS 110,000.

IN REGARDS TO A 2003 TOYOTA SIENNA XLE MODEL WITH HIGH INTENSITY DISCHARGE HEADLAMPS: IN JUNE OF 2007 WITH VEHICLE OUT OF WARRANTY BY MILEAGE, BUT NOT TIME, DRIVER'S SIDE HEADLIGHT STOPPED WORKING. INITIAL RECOMMENDATION BY DEALER (BOCH TOYOTA OF NORWOOD, MA) WAS TO REPLACE HID COMPUTER AT A COST OF 1,100 DOLLARS. FOLLOWING REPLACEMENT OF HID COMPUTER, LIGHT OPERATED FOR APPROXIMATELY THREE MONTHS BEFORE BEGINNING TO OPERATE INTERMITTENTLY. WAS THEN TOLD BY DEALER THAT THERE WAS A "SHORT IN THE BULB" AND DEALER RECOMMENDATION WAS TO REPLACE BULB ASSEMBLY AT COST OF 400 DOLLARS. WITHIN TWO WEEKS OF THIS REPAIR, I WAS STOPPED BY A POLICE OFFICER AND TOLD THE HEADLIGHT WAS NOT WORKING. AGAIN, HEADLIGHT IS WORKING INTERMITTENTLY. TODAY DEALER RECOMMENDED REPLACEMENT OF ENTIRE HEADLIGHT HOUSING AT A COST OF 1,100 DOLLARS. A BRIEF REVIEW OF POSTINGS TO TOYOTA OWNERS' FORUMS REVEALS MANY MENTIONS OF HID HEADLIGHT FAILURE IN NEW VEHICLES, PARTICULARLY THE 2006-2007 PRIUS MODELS. ALL DRIVERS REPORT INTERMITTENT OPERATION AND DEALERS WHO ARE UNABLE TO SOLVE THE PROBLEM. THE COMMON SOLUTION, "TOGGLE YOUR HEADLIGHT SWITCH OFF AND ON A FEW TIMES TO GET THEM WORKING AGAIN" IS A CLEAR SAFETY CONCERN, AND NOT AN APPROPRIATE REPAIR. *TR

CONDENSATION BUILDS UP IN THE PASSENGER HEADLIGHT. THE CONDENSATION REDUCES THE EFFECTIVENESS OF THE HEADLIGHT, CREATING A DARK SPOT ON THE RIGHT SIDE. THIS IS A COMMON PROBLEM WITH 2004 MODELS. THERE ARE HUNDREDS OF THREADS ON TOYOTA/SIENNA FORUMS ONLINE WHERE OWNERS ARE HAVING THE EXACT SAME PROBLEM. TOYOTA IS IGNORING THIS SAFETY PROBLEM. *TR
