WHILE SLOWING OUR 2005 PRIUS TO MAKE A TURN INTO A PARKING LOT THE BRAKES FAILED TO RESPOND NORMALLY. WARNING LIGHTS CAME ON TO INDICATE THE ABS/VSC HAD A PROBLEM. TOOK IT TO A REPAIR SHOP TO HAVE IT DIAGNOSED, DRIVING IT TO THE SHOP WAS HAZARDOUS, VERY TOUCHY AND SCARY TO DRIVE. THEY SAID IT NEEDED A COMPUTER ASSEMBLY, SKID CONTROL AND STROKE SENSOR ASSEMBLY TO REPAIR THE PROBLEM. OVER $2000 IN PARTS ALONE. CONSIDERING MY OPTIONS NOW. SELL AND NEVER BUY TOYOTA AGAIN WOULD BE ONE OPTION. IF THIS HAD HAPPENED AT HIGHWAY SPEED AND WE NEEDED TO SLOW OR STOP QUICKLY WE MAY HAVE HAD AN ACCIDENT! (ISSUE NOT COVERED BY WARRANTY) ISSUES LIKE LABELS FOR TIRE LOADS COVERED, RIDICULOUS!

TRACTION CONTROL ENGAGED ON A HILL WITH LIGHT SNOW COVER COMPLETELY STOPPING THE WHEELS AND PREVENTING ANY FORWARD MOTION, CREATING A DANGEROUS SITUATION. PEDESTRIANS HAD TO PUSH THE CAR UP THE HILL WHILE THE ACCELERATOR WAS PRESSED TO GET TO THE TOP. BACKING WOULD HAVE PLACED THE CAR IN A DANGEROUS POSITION WITH ONCOMING 50 MPH CROSS TRAFFIC . THERE SHOULD BE AN OVERRIDE FOR SITUATIONS SUCH AS THIS TO ENABLE SOME FORWARD MOTION TO BE MAINTAINED EVEN IF THERE IS SOME WHEEL SLIPPAGE. OCCURRED FRIDAY 14 FEB 2014. THIS HAS OCCURRED IN THE PAST ON GRAVEL DRIVEWAYS AND OTHER ROADS. THIS INSTANCE WAS BY FAR THE MOST TROUBLING SINCE PEDESTRIANS WERE INVOLVED. *TR

I ROLLED SLOWLY (<1 MPH) UPHILL TO THE PARKING SLOT (L.A. CODE, 2%GRADE DOWN AWAY FROM BUILDINGS) UP TO THE PARKING CEMENT STOP, AND WAS READY TO SHUT IT DOWN. THE ENGINE STARTED TO RACE, ABOUT TO GO OVER THE CEMENT STOP WHEN I PUT MY FOOT ON THE BRAKE. THE CAR CONTINUED OVER THE CEMENT STOP. I PUSHED HARDER ON THE BRAKE AND THE CAR STARTED TO DRIVE OVER THE SIDEWALK. THEN THE CAR DROVE THROUGH THE PLATE GLASS OF THE STUDIO AND THEN CAME TO A STOP INSIDE. I PUT THE CAR INTO NEUTRAL AND TRIED TO TURN THE CAR 'OFF'. THE CAR'S ENGINE WAS STILL ON AFTER SEVERAL TRIES TO TURN IT OFF AND I HAD MY FOOT OFF THE BRAKE AND ON THE FLOOR. THEN THE CAR TOOK A TURN TO THE LEFT AND DROVE THROUGH THE WALL (MY FOOT WAS STILL ON THE FLOOR). I GOT OUT OF THE CAR WITHOUT TAKING IT OUT OF NEUTRAL AND IT WAS STILL "ON". I TOOK THE KEY WITH ME TO THE MIDDLE OF THE ROOM (I USED THE KEYLESS IGNITION) SO THE CAR SHOULD HAVE "CHIMED" BECAUSE; THE PASSENGER SIDE DOOR WAS OPEN, I WAS OUT OF THE CAR, AND THE CAR WAS STILL LEFT "ON". HOWEVER, THE CAR DID NOT CHIME (INDICATING IT DID NOT DETECT I WAS 12 FEET AWAY). MY TEACHER CAME UP TO THE SHATTERED GLASS WINDOW OF THE STUDIO AT THE SAME TIME THE SECURITY OFFICER FOR THE MINI MALL A FEW MINUTES AFTER I GOT OUT OF THE CAR. I WAS LOOKING FOR MY INSURANCE CARD IN MY PURSE WHEN THE THREE OF US WITNESSED THE CAR "REV" AGAIN AND THE WALL BEGAN TO SHATTER WITH PLASTER AND WOODEN STUDS FALLING AROUND THE CAR WITH NO ONE DRIVING (THE CAR WAS IN NEUTRAL). BECAUSE OF THE MOVEMENT OF THE CAR, WITHOUT A DRIVER AND IN THE WALL, THE SECURITY GUARD TRIED TO GET PEOPLE OUT OF THE BUILDING. THE TOWING COMPANY COULD NOT 'PULL' THE VEHICLE OUT OF THE WALL WITH THEIR TOW TRUCK FOR MORE THEN 20 MINUTES SO, I GAVE MY CAR KEY TO THE POLICE OFFICER AND HE GAVE IT TO THE TOWING COMPANY. THE MAN FROM THE TOWING COMPANY DROVE THE CAR OUT OF THE WALL AND OUT OF THE STUDIO.

BRAKES ON 2005 TOYOTA PRIUS STARTED INTERMITTENTLY ACTING UP ABOUT A YEAR AGO, AFTER SIX YEARS OF NO PROBLEMS. OBSERVED SYMPTOMS WERE EXTREME JERKINESS OF BRAKE OPERATION DESPITE CONSTANT PRESSURE ON BRAKE PEDAL. SYMPTOMS OBSERVED AT ANY SPEED, BUT ESPECIALLY NOTICEABLE AT SLOW SPEEDS (COMING TO A FINAL STOP, SUCH AS AT A TRAFFIC LIGHT, OR IN REVERSE BACKING OUT OF DRIVEWAY). WHEN APPLYING BRAKES AT HIGHWAY SPEEDS, JERKINESS FELT LIKE ALTERNATE OVER BRAKING / UNDER BRAKING. SYMPTOMS WERE QUITE SCARY THE FIRST TIMES IT HAPPENED. HAD PERSONAL MECHANIC CHECK OUT BRAKES. TEST DRIVE CONFIRMED PROBLEM, BUT HE WAS UNABLE TO FIND ANYTHING WRONG WITH HYDRAULIC BRAKE SYSTEM. SINCE PROBLEM WAS INTERMITTENT, WE DECIDED TO SEE WHAT HAPPENED. PROBLEM CONTINUED INTERMITTENTLY, GRADUALLY INCREASING IN FREQUENCY TO THE POINT IN THE LAST MONTH WHERE IT WAS HAPPENING MUCH MORE OFTEN THAN NOT. TOOK CAR TO TOYOTA DEALER FOR DIAGNOSIS. PROBLEM WAS NOT EVIDENT ON DAY OF SERVICE. THEY CHECKED COMPUTER FOR STORED ERROR CODES, AND FOUND NONE. REAR BRAKE DRUMS SHOWED SLIGHT WEAR AND WERE OUT OF ADJUSTMENT, SO DRUMS WERE CLEANED AND TURNED AND BRAKES ADJUSTED. NO DIFFERENCE IN OBSERVED BEHAVIOR; BY END OF THE NEXT DAY, JERKY BEHAVIOR NOTED AS BAD AS IT HAD EVER BEEN. TOOK CAR BACK TO DEALER. THEY REPLACED THE STROKE SENSOR EVEN THOUGH THERE WAS NO STORED ERROR CODE. THIS APPEARS TO HAVE FIXED THE PROBLEM, SINCE THERE HAS BEEN NO RECURRENCE OF PROBLEM IN A WEEK OR DRIVING SINCE REPAIR. BRAKES FEEL TOTALLY NORMAL AGAIN, FOR THE FIRST TIME IN A YEAR. NOTE ON DIAGNOSIS PROCEDURE: THE DEALER SEEMED TO INITIALLY DISCOUNT MY DETAILED, WRITTEN DESCRIPTION OF THE PROBLEM, AND REACTED ONLY TO THEIR OBSERVATIONS. WHILE UNDERSTANDABLE, IT IS FRUSTRATING TO THE OWNER AND COULD LEAD TO A SERIOUS PROBLEM NOT GETTING FIXED. I FEEL THAT THE SYMPTOMS AS DESCRIBED TO THEM POINTED DIRECTLY TO THE STROKE SENSOR AND IT SHOULD HAVE BEEN REPLACED ON THAT BASIS. *TT

NO LIGHTS WERE LEFT ON NOR WERE ANY ELECTRICAL DEVICES PLUGGED INTO THE ACCESSORIES. WHEN IT STARTED UP THE CAR STATED THAT THE PARKING BRAKE WAS NOT PROPERLY ENGAGED AND THE VEHICLE NEEDED TO BE MOVED TO A LEVEL SURFACE. IT WAS IN MY DRIVEWAY. ANOTHER TIME THE CAR DID THE SAME THING, DYING AT WORK IN THE AIRPORT EMPLOYEE PARKING LOT. THE CAR REQUIRED BEING JUMP STARTED AND AGAIN IT GAVE THE SAME MESSAGE. A CO-WORKER STATED THAT THEY HAD HEARD THE CAR ALARM GO OFF AT ONE POINT ABOUT AN HOUR PRIOR TO SHIFT CHANGE. BOTH TIMES THE VEHICLE WAS CHECKED AND THE REPORT WAS NOTHING WAS WRONG WITH THE CAR. MOST RECENTLY ON 3/27/2011 THE SAME THING OCCURRED. THIS TIME WHEN JUMP STARTING THE BATTERY THE CARS ENGINE STARTED AND THE CAR LUNGED FORWARD AT ME WITH LIGHTS AND ALARM SOUNDING. I WAS UNABLE TO SHUT DOWN THE ALARM AND WENT INTO THE CAR AND PRESSED THE POWER BUTTON TO SHUT THE ENGINE DOWN. WHEN I POWERED THE ENGINE BACK UP THE CAR ALARM WAS AGAIN SOUNDING AND ALL THE LIGHTS ON THE DASH WERE ILLUMINATED. POWERED IT DOWN AND UP AGAIN AND THIS TIME NO AUDIBLE ALARM BUT THE EXCLAMATION MARK IN THE TRIANGLE WAS ILLUMINATED AS WELL AS THE MESSAGE ABOUT THE PARKING BRAKE. I POWERED IT DOWN AND UP ONE LAST TIME AND, WITH THE MESSAGE STILL ILLUMINATED, DROVE OFF. THE MESSAGE SHUT DOWN WHEN I GOT TO THE SECURITY GATE. TOYOTA TESTED THE VEHICLE ON 4/1/2011 AND REPORTED THAT C1300 AND C2300 FAULTS WERE FOUND (ECU AND ABS ACTUATOR). AS THE CAR IS OUT OF WARRANTY, COST WILL BE ABOUT $3,000.00.

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

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.
