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.

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!

3DP22005 · Pedestrian Alert Sounds
Opened Jan 27, 2023 · Closed Aug 7, 2023
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.
