2005 TOYOTA PRIUS STALLED ON AN OVERPASS WITH NO SHOULDERS. THE TRANSMISSION BECAME STUCK IN PARK, AND THE VEHICLE COULD NOT BE PUSHED SINCE THE FRONT WHEELS WERE LOCKED UP. THE CAR WAS EVENTUALLY TOWED, AND IT HAD TO BE DRAGGED ONTO THE FLATBED WRECKER SINCE THE FRONT WHEELS WOULD NOT ROLL. THE PROBLEM WAS DETERMINED TO BE A FAILED PUMP FOR COOLING THE INVERTER. THE PUMP FAILED SUCH THAT IT BLEW A FUSE THAT ALSO CONTROLLED THE TRANSMISSION SHIFTER, PREVENTING THE CAR FROM BEING PUT INTO NEUTRAL SO THAT IT COULD BE PUSHED OUT OF TRAFFIC LANES. THIS IS A VERY UNSAFE FAILURE MODE. *TR

2005 PRIUS STALLING PROBLEM!! I NEVER RECEIVED ANY NOTIFICATION ON THIS ISSUE. AS THE ARTICLE SAID"TOYOTA MOTOR SALES (TMS), U.S.A., INC., WILL LAUNCH A SPECIAL SERVICE CAMPAIGN INVOLVING CERTAIN 2004 AND EARLY 2005 MODEL YEAR PRIUS SOLD IN THE U.S. ON THE INVOLVED VEHICLES, AN ISSUE WITH THE PROGRAM LOGIC IN THE ELECTRONIC CONTROL MODULE (ECM) SYSTEM MAY CAUSE SOME OR ALL OF THE FOLLOWING WARNING LIGHTS TO ILLUMINATE: MASTER, HYBRID SYSTEM, ENGINE, VEHICLE STABILITY CONTROL, AND BRAKE. IF THIS OCCURS, THE VEHICLE WILL ENTER A "FAIL-SAFE" MODE WHICH ALLOWS LIMITED OPERATION VIA THE ELECTRIC MOTOR. HOWEVER, THE ELECTRICALLY-POWERED BRAKE AND STEERING OPERATION WILL CONTINUE TO FUNCTION NORMALLY IF THIS CONDITION OCCURS. THE ELECTRIC MOTOR WILL ALSO PROVIDE ENOUGH POWER TO ALLOW THE DRIVER TO PULL THE VEHICLE OVER AND AWAY FROM TRAFFIC. ONCE THE VEHICLE IS STOPPED, THE DRIVER MAY BE ABLE TO RESTART THE GASOLINE ENGINE IN THE VEHICLE BY PUSHING THE START BUTTON.TOYOTA IS PROACTIVELY CONDUCTING A CAMPAIGN IN THE INTEREST OF ITS CUSTOMERS. TOYOTA WILL INFORM OWNERS OF THE INVOLVED VEHICLES WITH A SPECIAL SERVICE CAMPAIGN NOTIFICATION LETTER SENT VIA FIRST CLASS MAIL BEGINNING IN LATE-OCTOBER. OWNERS ARE REQUESTED TO CONTACT THEIR LOCAL TOYOTA DEALER FOR DIAGNOSIS AND REPAIR UPON RECEIVING THEIR NOTIFICATION. TOYOTA WILL REPROGRAM THE ECM SYSTEM AT NO CHARGE TO THE OWNERS OF THE VEHICLE."

I'M WRITING ABOUT AN DEFECTIVE INVERTER COOLING PUMP IN MY 2005 TOYOTA PRIUS. I WAS DRIVING WHEN ALL OF A SUDDEN MY CAR LOSES THE ABILITY TO ACCELERATE. NUMEROUS WARNING LIGHTS CAME ON AS I COASTED TO A STOP IN A NEARBY NEIGHBORHOOD. THE CAR WOULD NOT SHUT OFF AT FIRST. AFTER I FINALLY GOT THE CAR TO TURN OFF, IT WOULD NOT TURN ON AGAIN. THE DISPLAY IN THE CENTER OF THE DASHBOARD WOULD COME ON FINE, BUT WHEN IT CAME TIME FOR THE MAIN ENGINE TO TURN ON (WHEN PUSHING THE START BUTTON), IT WOULD BLINK AND SHUT OFF IMMEDIATELY. WHEN I TOOK A LOOK UNDER THE HOOD, I COULD SMELL SOMETHING ELECTRICAL BURNING. I FINALLY GOT THE CAR TOWED TO A LOCAL SHOP THAT WAS TOYOTA/LEXUS CERTIFIED. THEY FIGURED OUT THAT THE INVERTER COOLING PUMP WAS DEFECTIVE AND IT WAS BLOWING FUSES (HENCE THE SMELL OF SOMETHING ELECTRICAL BURNING). TOTAL COST WAS ALMOST $500 FOR THE REPAIR: PARTS AND LABOR. I TRIED CALLING TOYOTA TO SEE IF I COULD GET ANY TYPE OF REIMBURSEMENT, BUT I GOT MANY REASONS WHY I SHOULD NOT GET ONE: - THE WARRANTY WAS FOR 60,000 OR 8 YEARS. I WAS IN THE 8 YEARS, THE MILEAGE WAS 62,000. (I GUESS CUSTOMER SERVICE DOES NOT MEAN MUCH - PREVIOUSLY I OWN A 94 TOYOTA COROLLA - 16 YEARS WITH A TOYOTA CAR) - I DID NOT GET IT REPAIRED AT A TOYOTA "DEALERSHIP" (EVEN THOUGH THEY WERE "TOYOTA" CERTIFIED) - I DID NOT BUY THE CAR NEW. (SO IF YOU BUY A USED TOYOTA, APPARENTLY THAT DOES NOT MAKE THE CAR A TOYOTA ANYMORE.) BOTTOM LINE, AFTER BEING FIXED THE CAR RUNS EVEN BETTER THEN BEFORE THE INVERTER COOLING PUMP FAILURE: BETTER GAS MILEAGE AND NO MORE PHANTOM STEERING WHEEL MOVEMENTS WHEN DRIVING ON THE HIGHWAY (HAPPENED WHEN THE ENGINE WOULD SWITCH OVER TO BATTERY AND VICE VERSA). *TR

I DRIVE A 2005 TOYOTA PRIUS. MY CAR HAS 26,000 MILES ON IT; WHICH IS VERY LOW MILEAGES. WHILE I WAS ON THE HIGHWAY, MY CAR`S LIGHTS ON THE DASHBOARD STARTS TO FLASH. THE BRAKE SYSTEM WARNING LIGHT AND BUZZER COMES ON ALONG WITH THE ABS WARNING LIGHT AND THE MALFUNCTION INDICATOR LAMP. I HAD NOWHERE TO PULL ASIDE. AFTER TWO MINUTES THE WARNING SIGNS SHUT OFF SO I KEPT DRIVING. FIVE MINUTES LATER, ALL THE WARNING LIGHTS COME ON SO I DECIDE TO GET OFF THE HIGHWAY TO TAKE IT TO THE KNOXVILLE TOYOTA DEALER. AS I`M EXITING THE HIGHWAY, I IMMEDIATELY REALIZED THAT I HAD NO BREAKS (WHEN I PRESSED THE BRAKE PEDAL WITH MY FOOT IT AUTOMATICALLY TOUCHED THE GROUND)! I REMEMBERED THAT MY DAD ALWAYS TOLD ME THAT IN CASE OF A BRAKE EMERGENCY TO PUMP THE PADDLE UNTIL THE BREAKS WORK. I ALMOST CRASHED INTO ANOTHER CAR; THE EXIT RAMP WAS VERY STEEP. I WAS GOING ABOUT 50 MILES PER HR BY THEN; LUCKILY I MANAGED TO STOP WHILE I KEPT PUMPING MY BREAKS. I TOOK IT TO THE DEALER RIGHT AWAY. THEY CHECKED MY CAR AND REPLACED: PUMP ASSY. WATER, SUPER LONG LIFE C, INVERTER COOLANT PUMP, SLIDING YOKE, REFLASHED ENGINE AND HV ECU AND SHAFT KIT. STEERI. I FOUND MY CASE VERY DANGEROUS AND MY LIFE WAS AT RISK. NOT ONLY WAS MY LIFE AT RISK BUT AS WELL AS OTHER INDIVIDUALS. I WOULD HATE FOR THIS TO HAPPEN TO SOMEONE ELSE! IT WAS SCARY AND I FELT LIKE MY LIFE MIGHT HAVE BEEN OVER. *TR

I WAS INVOLVED IN AN ACCIDENT WITH MY 2005 PRIUS ON 3/29/2006. THE CAUSE OF THE ACCIDENT REMAINS A MYSTERY. I WAS SITTING AT AN INTERSECTION, WAITING FOR TRAFFIC TO CLEAR. WITNESSES REPORTED THAT I PULLED OUT INTO THE ONCOMING TRAFFIC, RESULTING IN A COLLISION WITH ANOTHER VEHICLE. DUE TO THE INJURIES I SUFFERED (A MINOR CONCUSSION RESULTING IN RETROGRADE AMNESIA), I HAD NO RECOLLECTION OF THE PERIOD PRIOR TO ARRIVING AT THE INTERSECTION UP UNTIL THE PARAMEDICS REMOVED ME FROM THE VEHICLE. AS SUCH, I CAN'T EXPLAIN EXACTLY WHAT HAPPENED. WHILE I HAVE NO PROOF OF THIS, IT SEEMS THAT A POSSIBILITY WOULD BE AN ISSUE WITH THE STUCK ACCELERATOR THAT'S BEING REPORTED RELATING TO THE PRIUS. I'VE BEEN AT A LOSS TO EXPLAIN WHY I WOULD HAVE PULLED OUT IN FRONT OF ONCOMING TRAFFIC AT AN INTERSECTION THAT I WAS VERY FAMILIAR WITH. WHEN I HEARD OF THE ACCELERATION ISSUES WITH THE PRIUS, I WONDERED IF THAT COULD HAVE BEEN THE CAUSE. SINCE THE VEHICLE WAS TOTALED, IT'S NO LONGER AVAILABLE FOR INSPECTION. I THOUGHT I'D SUBMIT THIS REPORT TO ADD TO THE SUSPECTED CASES OF ACCELERATOR ISSUES. *TR

I AM WRITING ABOUT AN INCIDENT WITH MY 2005 TOYOTA PRIUS. ON JULY 20, 2009 AS MY WIFE WAS DRIVING OUR PRIUS THE ENGINE LIGHT WENT ON. SHE IMMEDIATELY DROVE INTO THE PARKING LOT OF A SMALL BUSINESS AND STOPPED THE CAR. WE HAD IT TOWED TO A REPAIR SHOP. THE MECHANICS THERE DIAGNOSED THE PROBLEM. THE INVERTER PUMP THAT SUPPLIES COOLANT TO ALL THE ENGINE PARTS HAD MALFUNCTIONED. THE MECHANICS TOLD US THAT THE TOYOTA COMPANY WAS AWARE THAT THIS PROBLEM COULD OCCUR ON OUR 05 PRIUS. IF WE HAD THE CAR TOWED TO A TOYOTA DEALER THE DEFECTIVE INVERTER PUMP WOULD BE REPLACED WITH A MORE RECENT MODEL FREE OF CHARGE. THE NEXT DAY WE HAD THE CAR TOWED TO THE DEALERSHIP. THEY EXAMINED THE CAR AND VERIFIED THAT THE PROBLEM WAS A DEFECTIVE INVERTER PUMP. THEIR CODES AS PRINTED ON THEIR INVOICE NUMBER 524093 [21 JULY 2009] ARE "34352 PULLED CODE POA93, SUB CODE 346-INVERTER COOLING SYSTEM PERFORMANCE. FOUND TSB EG001-07 TO CORRECT THIS CONCERN. REPLACED INVERTER WATER PUMP AS PER STB." THIS CATASTROPHIC MALFUNCTION OCCURRED WITHOUT ANY PRIOR WARNING. WE HAVE MAINTAINED THE CAR WITH REGULAR MAINTENANCE AS PER THE SCHEDULE IN THE OWNERS MANUAL. WE WERE VERY LUCKY THAT THE MALFUNCTION OCCURRED WHILE WE WERE IN TOWN. SINCE WE LIVE IN NEW MEXICO THE MALFUNCTION COULD HAVE OCCURRED OUT IN ONE OF OUR DESERTS OR ON ONE OF OUR MOUNTAINS. WE ARE BOTH 73 YEARS OF AGE AND BOTH CANCER SURVIVORS. THE LAST THING THAT WE NEEDED WAS TO BE STRANDED SOMEWHERE OR TO HAVE THE ENGINE COMPLETELY DESTROYED IF WE WERE NOT ABLE TO IMMEDIATELY STOP THE CAR. I DO HOPE THAT TOYOTA WILL BE REQUIRED TO PERFORM A RECALL ON THE PRIUS MODELS THAT HAVE THIS TYPE IF INVERTER PUMP SO THAT OWNERS CAN CONTINUE TO DRIVE THEIR CARS SAFELY. *TR

TOYOTA IS RECALLING CERTAIN MODEL YEAR 2004-2010 PASSENGER VEHICLES. THE ACCELERATOR PEDAL CAN GET STUCK IN THE WIDE OPEN POSITION DUE TO ITS BEING TRAPPED BY AN UNSECURED OR INCOMPATIBLE DRIVER'S FLOOR MAT.
Consequence & remedy
Consequence: A STUCK OPEN ACCELERATOR PEDAL MAY RESULT IN VERY HIGH VEHICLE SPEEDS AND MAKE IT DIFFICULT TO STOP THE VEHICLE, WHICH COULD CAUSE A CRASH, SERIOUS INJURY OR DEATH.
Remedy: TOYOTA FILED AN AMENDED DEFECT REPORT ON NOVEMBER 25, 2009, STATING THAT DEALERS WILL MODIFY THE ACCELERATOR PEDAL AND, ON CERTAIN VEHICLES, ALTER THE SHAPE OF THE FLOOR SURFACE UNDER THE PEDAL. THESE CHANGES ADDRESS THE RISK OF PEDAL ENTRAPMENT DUE TO INTERFERENCE WITH THE FLOOR MAT. REDESIGNED ACCELERATOR PEDALS WILL BECOME AVAILABLE BEGINNING IN APRIL 2010 AND DEALERS WILL REPLACE ANY MODIFIED PEDAL WITH THE NEW PEDAL IF DESIRED. ALSO, DEALERS WILL REPLACE ANY GENUINE TOYOTA OR LEXUS ALL-WEATHER FLOOR MATS WITH REDESIGNED ALL-WEATHER MATS, OR REPURCHASE THE PREVIOUS MATS FROM OWNERS WHO DO NOT WANT THE NEW ONES. ADDITIONALLY, SOFTWARE MODIFICATIONS WILL BE INSTALLED ON CAMRY, AVALON AND LEXUS ES 350, IS 350 AND IS 250 MODELS THAT WILL ENSURE THAT THE BRAKE OVERRIDES THE ACCELERATOR IN THE EVENT BOTH BRAKE AND ACCELERATOR PEDALS ARE APPLIED.

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

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
