CAR WAS BEING DRIVEN ON MULTI-LANE CITY ARTERIAL IN MODERATE TRAFFIC. TO TRY TO QUICKLY AVOID AN OBSTRUCTING VEHICLE AHEAD, DRIVER RAPIDLY DEPRESSED ACCELERATOR PEDAL TO FULLEST EXTENT WHILE STEERING. CAR THEN IMMEDIATELY, AND WITHOUT WARNING, LOST ALL ENGINE POWER AND ROLLED TO A STOP. TWO GENERAL WARNING LIGHTS ON DASHBOARD ILLUMINATED. REPEATEDLY DEPRESSING ACCELERATOR PEDAL PRODUCED NO MOTION OR OTHER RESULT. AFTER ENGAGING EMERGENCY FLASHERS, ONLY WAY TO REGAIN ENGINE POWER WAS TO SHUT OFF IGNITION, WHICH REQUIRED ENGAGING PARKING CIRCUIT AND DEPRESSING POWER ON/OFF BUTTON, THEN AFTER SHUTDOWN PROCEDURE WAS COMPLETE, AGAIN PRESSING POWER ON/OFF BUTTON AND WAITING FOR HYBRID SYSTEM TO ENERGIZE. WARNING LIGHTS AGAIN CAME ON BUT CAR NOW RESPONDED TO ACCELERATOR AND DRIVER WAS ABLE TO MOVE TO PARKING LANE. THIS WAS THE THIRD TIME IN THE EIGHT MONTHS OF OWNING THIS NEW CAR THAT SUCH A SUDDEN SHUTDOWN OCCURRED. AFTER THE FIRST TWO TIMES IN LATE NOVEMBER-EARLY DECEMBER 2004, CAR HAD BEEN TAKEN TO DEALER FOR SERVICE AND WAS RETURNED TO OWNERS REPORTED AS FIXED BY REPLACING FAULTY ACCELERATOR SENSOR.

WHILE CAR WAS GOING ABOUT 25 MPH, IT WENT FROM "DRIVE" TO "PARK". IT STOPPED ABRUPTLY. COULD NOT GET CAR BACK IN DRIVE EXCEPT MOMENTARILY. THE CAR'S ELECTRIC SYSTEM CYCLED ON AND OFF ON A 16 TO 20 SECOND PERIOD. THAT IS, IT WOULD BE ON AND IN PARK AND THEN SHUT OFF MOMENTARILY EVERY 18 SECONDS. IT CONTINUTED DOING THIS FOR ABOUT 10 MINUTES WHEN I STOPPED MONORITING IT. I HAD THE CAR TOWED TO A TOYOTA DEALER. WHEN IT WAS EXAMINED ABOUT 2 HOURS AFTER THE INCIDENT, IT WORKED FINE AND THERE WAS NO COMPUTER FEEDBACK ON THE PROBLEM. THEY DIDN'T KNOW WHAT HAPPENED OR WHAT TO DO. THEY SAID TO BRING IT BACK WHEN THE PROBLEM HAPPENED AGAIN. THIS COULD BE A LIFE THREATENING GLITCH IF IT OCCURED AT FREEWAY SPEEDS IN TRAFFIC. I BELIEVE TOYOTA SHOULD PUT ALL CARS THAT THIS HAS HAPPENED TO ON THE SIDELINES UNTIL THEY FIND OUT WHAT THE PROBLEM IS AND THEN COME UP WITH A FIX. BECAUSE OF THE REAL POSSIBILITY OF INJURIES, NHTSA SHOULD START AN INVESTIGATION AND START PUSHING TOYOTA TO TAKE THIS SERIOUSLY.

DP22005 · 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

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.
