INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). I OWN A 2007 TOYOTA PRIUS, I HAVE BEEN HAVING THE SAME ISSUES OTHER DRIVERS ARE REPORTING IN THAT THE VEHICLE WILL INCREASE SPEED WHEN GOING OVER BUMPS, OR ON A SLIPPERY ROAD. I ALWAYS ASSUMED IT WAS SOME TRACTION CONTROL SYSTEM AND IT WAS NORMAL, HOWEVER THE RECENT NEWS STORIES HAVE MADE ME AWARE THAT MY SITUATION WITH MY VEHICLE IS NOT NORMAL. I HAVE CONTACTED TOYOTA ABOUT THIS MAJOR ISSUE, HOWEVER THEY ADVISED ME THAT BECAUSE THE VEHICLE IS NO LONGER UNDER WARRANTY THAT THEY ARE NOT HELD LIABLE FOR THE VEHICLE. THEY ALSO STATED THAT DUE TO NO RECALL BEING ISSUED FOR THIS MODEL AND YEAR THAT NOTHING CAN BE DONE, UNLESS I AM WILLING TO PAY TO HAVE THE ISSUE AT HAND RESOLVED. I DO FEEL THAT THE BRAKING ISSUE IS IDENTICAL TO THE 2010 ISSUES. NOT SURE WHAT TO DO, AND THEREFORE I AM WRITING TO YOU. THE INCIDENT DATE WOULD BE WHEN EVER I DRIVE MY VEHICLE, NO CRASH HAS HAPPENED YET HOWEVER. [XXX] *TR

2007 TOYOTA PRIUS - BRAKING ISSUE ON RAINY OR SLICK SURFACE. UPON NORMAL BRAKING ON A SLICK OR WET SURFACE THE CAR BECOMES UNSTABLE, THE ABS BRAKING BECOMES IRREGULAR AND THE CAR GOES INTO A SKID AND DOES NOT STOP IN A NORMAL FASHION OR WITHIN A NORMAL BRAKING DISTANCE. THE SAME BRAKING RESPONSE OCCURS IF I HIT A POTHOLE WHILE BRAKING. THE TOYOTA DEALER TELLS ME THAT THIS IS NORMAL. IT IS NOT NORMAL AS I CANNOT DRIVE THE CAR UNDER WET OR SNOWY CONDITIONS FOR FEAR OF AN ACCIDENT. THE BRAKING ISSUES NOTED IN THE 2010 PRIUS MAKE ME WONDER IF A SIMILAR CONDITION EXISTS FOR THE 2007 MODEL YEAR. I SUSPECT THAT IT IS THE ECU WHICH IS FAULTY. *TR

I HAVE OWED BOTH A 2005 AND 2007 PRIUS AND HAVE EXPERIENCED TWO PROBLEMS WITH BOTH VEHICLES THAT ARE A SAFETY CONCERN, ALTHOUGH NO ACCIDENT HAS RESULTED FROM THESE PROBLEMS. 1) IN SNOWY CONDITIONS, WHEN TRAVELING UP AN INCLINE, THE TRACTION CONTROL SYSTEM CAN TURN OFF POWER TO BOTH DRIVE WHEELS WITH THE RESULT THAT THE CAR CAN NOT MAKE IT UP THE HILL. GRANTED THIS CAN HAPPEN EVEN TO A MORE CONVENTIONAL CAR, BUT THE PRIUS DOES THIS UNDER CIRCUMSTANCES WHEN OTHER CARS HAVE NO PROBLEM NEGOTIATING THE HILL. THE OWNERS MANUAL CLAIMS THAT THIS IS TO PROTECT THE ELECTRIC ENGINE, HOWEVER, IT SEEMS THAT THERE SHOULD BE AN OVERRIDE OF SOME SORT THAT ALLOWS THE INTERNAL COMBUSTION MOTOR TO TURN THE WHEELS WHEN TRACTION IS POOR. THIS SYSTEM HAS ALSO LED TO CIRCUMSTANCES IN PARKING LOTS DURING SNOW, WHERE IT BECOMES IMPOSSIBLE TO MOVE THE CAR EVEN THOUGH OTHER CONVENTIONAL CARS ARE ABLE TO NEGOTIATE THE SNOW WITHOUT A PROBLEM. 2) IN CIRCUMSTANCES WHERE THE PRIUS MUST MERGE QUICKLY INTO TRAFFIC FOR INSTANCE WHEN TURNING INTO BUSY TRAFFIC AT AN INTERSECTION, IF YOU FLOOR THE GAS PEDAL THE CAR INITIAL ACCELERATES, BUT THEN THE ACCELERATION FADES DRAMATICALLY, BEFORE IT RESURGES. THIS CAN BE CIRCUMVENTED BY NOT PRESSING THE GAS PEDAL SO HARD, HOWEVER, THE INSTINCT IS TO STEP ON THE GAS AS HARD AS POSSIBLE. THIS IS NOT ONLY HAIR-RAISING WHEN IT HAPPENS, BUT ALSO COULD LEAD ON AN ACCIDENT. *TR

MY WIFE HAS A 2007 PRIUS, ON WHICH WE RUN DUNLOP GRASPICS SNOW TIRES, 185/65R15, IN THE WINTER, ON ALL 4 CORNERS. WE HAVE RUN THE GRASPICS ON A DODGE CARAVAN, FORD MUSTANG, AND ACURA RSX, WITH GOOD RESULTS, ON SNOWY / ICY ROADS. ANYWAY, WE WERE IN CANADA, DECEMBER 6, 2008, BEAUTIFUL SUNNY DAY, TEMP ABOUT 6 DEG. F. ROADS IN THE CITY HAD 1 - 2 INCHES OF SNOW, WITH ENOUGH SALT TO MAKE A NICE GREASY MIXTURE, (TOO COLD TO MELT THE SNOW). I STOPPED AT A STOP SIGN BEFORE MAKING A LEFT TURN. FROM FULL STOP, AND THERE WERE SOME ON COMING CARS BUT A DISTANCE AWAY, I GENTLY STEPPED ON THE GAS TO MAKE THE TURN - NOTHING - OKAY THE TRAFFIC A LITTLE CLOSER, BUT STILL A LONG WAYS AWAY. I GIVE IT A LITTLE MORE GAS, AND MAYBE WE ARE MOVING. FINALLY IT IS CREEPING ACROSS, AND WE COMPLETE THE LEFT TURN WITH NO BENT SHEET METAL. AFTER THIS EXPERIENCE, AND WITH NO ONE ELSE IN THE PRIUS, I DID SOME EXPERIMENTING. THE TRACTION CONTROL APPEARS TO WORK TOO WELL. IT SEEMS TO ALLOW NO SLIPPAGE, AND THERE IS NO FEELING OF FORWARD PROGRESS, OR THAT THE TIRES ARE EVEN TRYING. I DID FIND SOME SIMILAR COMMENTS ON THE INTERNET. I CALLED TOYOTA AND THEY ARE SO CONCERNED ABOUT DAMAGE TO THE PRIUS DRIVETRAIN THAT THE TRACTION CONTROL IS DESIGNED TO ALLOW NO SLIPPAGE. THE PERSON ON THE PHONE AT TOYOTA SAID THAT IF THE TIRES SPUN AND THEN GOT TRACTION, THERE MAY BE DAMAGE RESULTING IN A $6000 REPAIR BILL. I SAID, %$#@ THE $6000; I HAD 4 PEOPLE IN A CAR THAT WAS VERY DANGEROUS AT SNOWY INTERSECTIONS. I ASKED TO TALK TO SOME ONE ELSE AND GOT NO DIFFERENT ANSWER, EXCEPT THAT THEY HAD RECEIVED SIMILAR CALLS, AND THE ONLY ADVICE WAS TO USE SNOW TIRES. NO DEATHS OR INJURIES. NO FIRE NO CRASH. NOT REPORTED TO POLICE. *TR

Toyota is recalling certain model year 2004-2009 Prius vehicles manufactured August 6, 2003, through March 30, 2009 and FCHV-adv vehicles manufactured December 12, 2008, through September 13, 2011. During manufacturing, a scratch may have occurred inside of the electrically driven water pump at the coil wire. The coil wire may corrode at the scratched portion.
Consequence & remedy
Consequence: The corroded coil wire may break and the water pump could stop. The corroded coil wire could cause a short circuit between coil wires and a possible open fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. This may increase the risk of a vehicle crash.
Remedy: Toyota will notify its owners, and dealers will replace the electric water pump, free of charge. The recall began on January 17, 2013. Owners may contact their Toyota dealer or the Toyota Customer Experience Center at 1-800-331-4331.

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.

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 THIS INVESTIGATION AFTER RECEIVING REPORTS THAT BOTH HEADLIGHTS WOULD GO OUT, OR EXTINGUISH WHILE DRIVING.THE SUBJECT VEHICLES ARE EQUIPPED WITH HIGH INTENSITY DISCHARGE (HID) HEADLAMPS THAT OPERATE ON INDEPENDENT LAMPS AND ECU'S (ELECTRONIC CONTROL UNITS) FOR EACH HEADLIGHT, MEANING THAT EACH HEADLIGHT RUNS INDEPENDENTLY OF THE OTHER, AND A FAILURE IN ONE LAMP OR ECU DOES NOT NECESSARILY RESULT IN A FAILURE OF THE OTHER.DURING THE INVESTIGATION, A RANDOM SAMPLE OF FORTY CONSUMERS WAS CONTACTED BY ODI IN A TELEPHONE SURVEY TO VERIFY THEIR EXPERIENCES.THE CONSUMERS STATED IN COMPLAINTS TO TOYOTA THAT BOTH HEADLIGHTS FAILED AT THE SAME TIME.ODI DISCOVERED THROUGH TALKING WITH THESE COMPLAINANTS THAT IN FACT ONE HEADLIGHT WOULD BEGIN TO FLICKER AND THEN CUT OFF.THE OTHER HEADLIGHT WOULD STILL BE OPERATIONAL.IN A FEW CASES WHERE NO ACTION WAS TAKEN, SOME COMPLAINANTS STATED THAT AFTER A FEW MONTHS BOTH HEADLAMPS WOULD BEGIN TO FAIL RESULTING IN NO HEADLIGHTS; HOWEVER NONE REPORTED THAT BOTH LAMPS FAILED SIMULTANEOUSLY.COMPLAINANTS ALSO STATED THAT THEY COULD TOGGLE THE HEADLAMP SWITCH ON AND OFF TO TEMPORARILY RESTORE LIGHTING WHEN THIS CONDITION OCCURRED, EVEN IN CASES WERE BOTH HEADLAMPS WERE EXTINGUISHED.THE RESULTS OF THIS SURVEY ARE LARGELY CONSISTENT WITH ODI'S ASSESSMENT OF THE REPORTS AND WARRANTY DATA.TOYOTA SUBMITTED IN RESPONSE TO ODI'S INFORMATION REQUEST LETTER THAT, GENERALLY SPEAKING, ONLY ONE LAMP FAILED AT A TIME, AND THAT TOGGLING THE SWITCH RESTORED THE LAMP.TOYOTA REQUESTED A MEETING WITH ODI AND ON AUGUST 6, 2009, PRESENTED THEIR ASSESSMENT OF HEADLAMP FAILURE.TOYOTA CONFIRMED THAT A HEADLAMP COULD EXTINGUISH WHILE DRIVING DUE TO A BULB FAILURE, AND THAT IT COULD BE TEMPORARILY RESTORED BY TURNING THE HEADLIGHT SWITCH ON AND OFF, AND THAT SIMULTANEOUS FAILURE OF BOTH HEADLAMPS WAS RARE AND UNLIKELY.TOYOTA ALSO BRIEFLY DISCUSSED THEIR INTENTION TO CONDUCT A CUSTOMER SERVICE CAMPAIGN TO ADDRESS CONSUMER DISSATISFACTION WITH HID BULB FAILURES.SINCE THERE IS STILL ONE HEADLIGHT OPERATING WHEN THE OTHER ONE CUTS OFF, THERE IS STILL LIGHTING AVAILABLE TO GET THE VEHICLE TO A REPAIR FACILITY.THUS, A SAFETY DEFECT TREND HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES 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 TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.
