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.

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 ALS…

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…

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

Status: closed (inferred from source dates) · Electrical System:propulsion System
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

Status: closed (inferred from source dates) · Steering; Steering:column; Steering:linkages
The Office of Defects Investigation (ODI) received a January 2013 defect petition requesting that it open an investigation on Model Year (MY) 2004-2009 Toyota Prius vehicles to address a possible manufacturing safety defect related to the steering column intermediate shaft.During the defect petition evaluation, ODI: 1.Reviewed the petition and its enclosures; 2.Reviewed the subject steering system layout; 3.Examined the Petition Vehicle?s history, including its repair history; 4.Reviewed and followed-up potentially related consumer complaints; 5.Assessed Safety Recalls 06V-188 and 12V-537; and, 6.Requested and examined complaint, claim, field report, service history, and warranty information from Toyota.ODI's review revealed that the petition vehicle had been recalled (Recall 06V188) to remedy a defect in the system identified in the petition with the remedy taking place prior to the failure that prompted the petition. Circumstances point to incorrect reassembly of the petitioner's vehicle by those who performed the recall remedy.ODI examined the issues raised by this petition to identify any related safety defect trend in the general subject vehicle population.That review identified a low rate of related consumer complaints (twenty-five over a eight year period from a population of over 600,000 vehicles) and no pattern that would identify either a safety defect not already covered by the two existing steering safety recalls by Toyota or a systematic problem with either recall remedy.Based on this evaluation, ODI does not believe that additional investigation will lead to a finding that a defect related to motor vehicle safety exists in the subject vehicles. Therefore, in view of the need to allocate and prioritize NHTSA?s limited resources to best accomplish the agency's safety mission, the petition is denied. The denial of this petition does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take further action if warranted by the circumstances.For more information, see the Federal Register notice in the public file for this action (https://www.nhtsa.gov/recalls#vehicle, select NHTSA ID, enter: DP13001)The ODI reports cited above can be reviewed on-line (https://www.nhtsa.gov/recalls#vehicle) under the following NHTSA ID numbers:10407520, 10418710, 10429551, 10473654, 10478195, 10478053, 10437229, 10489425, 10510722, 10639984, 10648277, 10499778, 10712626, 10723196, 10787530, 10808124, 10838803, 11071646, 11098144, 11099507, 11102659, 11160767, 11192607, 11287550, 11287606

ODI OPENED PE05-029 BASED ON 33 REPORTS OF ALLEGED GASOLINE ENGINE STALLING ON THE SUBJECT VEHICLES.THE SUBJECT VEHICLES ARE GASOLINE/ ELECTRIC HYBRID VEHICLES THAT CAN BE OPERATED IN GASOLINE OR ELECTRIC MODES, OR A COMBINATION OF BOTH DEPENDING ON THE POWER DEMAND.ALL REPORTS ALLEGE THAT THE GASOLINE ENGINE SHUT DOWN SUDDENLY WITHOUT WARNING.SOME OF THE COMPLAINANTS REPORTED THAT THE VEHICLE CONTINUED TO OPERATE USING THE ELECTRIC MODE FOR A PERIOD OF TIME AFTER THE GAS ENGINE STALLED AND SOME REPORTED THAT THE VEHICLE SHUT DOWN AT THE SAME TIME THAT THEY FELT THE GAS ENGINE STALLED.SOME CONSUMERS REPORTED THAT THEY WERE ABLE TO RESTART THE VEHICLE EITHER IMMEDIATELY OR AFTER ALLOWING THE VEHICLE SIT FOR A SHORT TIME, WHEREAS OTHERS REPORTED THAT THEY HAD THEIR VEHICLE TOWED.DURING PE05-029, ADDITIONAL FAILURE DATA WAS IDENTIFIED AS NOTED IN THE FAILURE REPORT SUMMARY ABOVE.THE COMPLAINT DATA REPRESENTS INCIDENTS WHERE ENGINE STALLING WAS ALLEGED OR WHERE THE VEHICLE WAS ALLEGED TO HAVE ONE OF THE VARIOUS CONDITIONS THAT CAUSES THE GAS ENGINE TO STALL.IN ITS AUGUST 26, 2005 RESPONSE TO ODI'S INFORMATION REQUEST, TOYOTA IDENTIFIED VARIOUS CONDITIONS THAT COULD CAUSE THE SUBJECT VEHICLES TO EXPERIENCE A GAS ENGINE STALL.IF THIS HAPPENS, THE DRIVER IS ALERTED BY AN AUDIBLE SOUND AND VARIOUS WARNING LIGHTS.THE VEHICLE WILL CONTINUE TO OPERATE IN THE ELECTRIC MODE AND THE ELECTRICALLY-POWERED BRAKE AND STEERING OPERATION WILL CONTINUE TO FUNCTION NORMALLY. ANALYSIS OF THE WARRANTY DATA INDICATED THAT OVER 97% OF VEHICLES EXPERIENCING A GAS ENGINE STALL RESULTED FROM AN ISSUE WITH THE PROGRAM LOGIC IN THE ELECTRONIC CONTROL MODULE (ECM) SYSTEM, WHICH MAY CAUSE THE ECM SYSTEM TO NOT START THE GAS ENGINE WHEN REQUIRED.AS A RESULT, THE VEHICLE WILL ENTER THE LIMITED OPERATION MODE DESCRIBED ABOVE.THE MAJORITY OF THE ODI COMPLAINTS ALSO INDICATED THAT THE DRIVER EXPERIENCED THIS CONDITION IN CONJUNCTION WITH THE ENGINE STALL. DURING OCTOBER 2005, TOYOTA INFORMED ODI THAT IT WOULD INITIATE A SPECIAL SERVICE CAMPAIGN (SSC) TO REPROGRAM THE ECM SOFTWARE ON APPROXIMATELY 75,000 MY 2004 AND EARLY 2005 SUBJECT VEHICLES TO ADDRESS THE GAS ENGINE STALLING CONDITION.DURING THIS SSC, DEALERS WILL ALSO APPLY SPECIAL DIELECTRIC GREASE TO A TRANSAXLE CONNECTOR TO PREVENT WATER INTRUSION WHICH MAY ALSO CAUSE SIMILAR LIMITED OPERATION CONDITIONS.BASED ON ODI'S ANALYSIS, THIS REMEDY SHOULD ADDRESS MOST OF THE INCIDENTS RESULTING IN A LIMITED OPERATION MODE.GIVEN THESE CIRCUMSTANCES, FURTHER USE OF THE AGENCY RESOURCES IN THIS MATTER DOES NOT APPEAR TO BE WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL CONTINUE TO MONITOR COMPLAINTS AND OTHER INFORMATION RELATING TO THE ALLEGED DEFECT IN THE SUBJECT VEHICLES AND TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED.
