AFTER LISTENING TO PUBLICITY ABOUT THE 2010 PRIUS PROBLEM I REALIZE THAT I HAVE HAD THE SAME PROBLEM OF BRAKE FADE IN MY 2005 PRIUS. THERE IS A BRIDGE SECTION THAT I DRIVE OVER SEVERAL TIMES A MONTH. THIS BRIDGE SECTION IS 1 INCH HIGHER THAN THE ASPHALT ROAD AND ON A STEEP HILL IMMEDIATELY BEFORE A STOP SIGN. SO IF I AM BRAKING AS I HIT THE BRIDGE SECTION, I NOTICE AN IMMEDIATE BRAKE FADE. SO FOR ALL THESE YEARS, I ASSUMED IT WAS AN ABS PECULIARITY WITH CAR UNWEIGHTING. I'VE LEARNED TO BRAKE HARD IMMEDIATELY BEFORE I ENTER THE BRIDGE SECTION, RELEASE THE BRAKES AS I HIT THE EDGE OF THE BRIDGE SECTION, BRAKE HARD ON THE BRIDGE SECTION AND RELEASE AS I DROP OFF THE SECTION, THEN BRAKE TO THE STOP SIGN. I HAVE NEVER EXPERIENCE THIS PROBLEM IN OTHER SITUATIONS BUT I AM AWARE OF THE BRAKE FADE AND MIGHT BE ANTICIPATING THE PROBLEM. IT HAS BEEN OCCURRING SINCE I PURCHASED THE CAR IN 2005. *TR

MY WIFE AND I RECENTLY BOUGHT A USED 2005 PRIUS FROM WILDE TOYOTA IN WEST ALLIS, WI. IN THE LAST FEW MONTHS WE HAVE EXPERIENCED BRAKING ISSUES WITH THE VEHICLE ON ICY ROADS, SLICK ROADS, AND SNOW COVERED ROADS. WE HAVE HAD THREE BRAKE FAILURES. THE FIRST WAS WHEN I WAS DRIVING ON A SIDE-STREET. I WAS GOING SLOW, LESS THEN 15 MILES PER HOUR, AND STEPPED ON THE BRAKES TO MAKE A TURN. THE BRAKES WERE UNRESPONSIVE FOR APROX. 2 SECONDS CAUSING ME TO ROLL BEFORE THE BRAKES ENGAGE. THE SECOND OCCURED WHEN MY WIFE WAS DRIVING AT A LOW SPEED, UNDER 40 MILES AN HOUR, ON A MAIN ROAD. AS SHE APPROACHED THE STOPLIGHT SHE STEPPED ON THE BRAKES, WHICH ALSO FAILED TO ENGAGE. DUE TO HER HIGHER SPEED SHE ROLLED OVER 10 FEET AND CAME CLOSE TO HITTING THE CAR STOPPED IN FRONT OF HER BEFORE THE BRAKES FINALLY ENGAGED. THE FINAL OCCURANCE ALSO OCCURED WHEN MY WIFE WAS DRIVING, THIS TIME AT A HIGHER SPEED BETWEEN 40 AND 50 MILES PER HOUR, WHEN PRESSING ON THE BRAKES ON AN OVERPASS THE BRAKES FAILED TO ENGAGE AND THE CAR PHYSICALLY SEEMED TO SHAKE A BIT. AFTER BEING UNABLE TO STOP FOR SEVERAL FEET THE BRAKES FINALLY ENGAGED. WE BELIEVE THESE OCCURANCES ARE DUE TO AN ERROR WITH OUR ABS SYSTEM. IN EACH OCCURANCE THE "SLIPPERY ROAD" WARNING HAS APPEARED. WE TOOK IT TO WILDE TAYOTA THIS MORNING. AFTER SOFTWARE TESTING AS WELL AS ROAD TESTING ON THEIR SNOW COVERED LOT THEY FAILED TO REPLICATE THE PROBLEM. NO SYSTEM ERRORS WERE PRESENT AND THEY WERE UNABLE TO TAKE ANY FURTHER ACTION. WE ARE, HOWEVER, STILL CONVINCED THAT A PROBLEM EXISTS. IF IT OCCURS AGAIN WE WILL ONCE AGAIN TAKE IT TO THE DEALERSHIP AND TRY TO REPLICATE THE PROBLEM. *TR

ABS SYSTEM FAILURE WHILE PREPARING TO STOP FROM 40 MPH IN 05 TOYOTA PRIUS LAST SEPTEMBER. HAD AT LEAST THREE OCCURRENCES DURING THE SUMMER OF THE BRAKE PEDAL GOING QUICKLY AND EASILY TO THE FLOOR, MAKING A "THUNK" NOISE, SOUNDING AND FEELING LIKE METAL ON METAL, BUT THIS WOULD NOT HAPPEN AGAIN WHEN I STEPPED ON THE BRAKES AGAIN IMMEDIATELY, AND CERTAINLY DIDN'T HAPPEN FOR MY MECHANIC TO HEAR. TOYOTA DIAGNOSED A COMPUTER FAILURE THAT COST ME $2000 TO REPLACE. *TR

I OWN A 2005 PRIUS, BOUGHT NEW. I NOW HAVE 130,000 MILES ON IT. IT HAS BEEN SERVICED AND MAINTAINED AT SCHEDULED INTERVALS, MOSTLY BY A TOYOTA DEALER. #1: I HAVE COMPLAINED TO THE DEALER SINCE THE FIRST WINTER THAT I BOUGHT THE CAR THAT THE "TRACTION CONTROL SYSTEM" IS DANGEROUS IN BAD WEATHER CONDITIONS. WHENEVER THE ROAD IS SLIPPERY, IF THE CAR SENSES WHEELSPIN, IT CUTS POWER TO THE ENGINE. THIS IS SCARY IF YOU'RE PULLING OUT INTO TRAFFIC ON A RAINY DAY, AS THE CAR WILL SOMETIMES JUST QUIT RUNNING FOR A SECOND, LEAVING YOU VULNERABLE TO ONCOMING TRAFFIC. SNOW IS FAR WORSE. I LIVE ON A HILLY ROAD. IF IT'S SNOWY THE CAR WILL SLOW DOWN, AND SIMPLY STOP TRYING TO MOVE FORWARD ON THE FIRST STEEP SLOPE I COME TO. IT DOESN'T MATTER HOW HARD I MASH ON THE ACCELERATOR, OR IF I BACK OFF AND TRY AGAIN, THE CAR WILL NOT ATTEMPT TO MOVE. ONCE THE CAR STOPS MOVING FORWARD IT BEGINS TO SLIDE BACKWARDS, AND CONTROL IS TOTALLY LOST. I WAS NEARLY KILLED THE FIRST TIME THIS HAPPENED (IN ABOUT ONE INCH OF SNOW) AS MY CAR EVENTUALLY SLIPPED SIDEWAYS ACROSS THE ONCOMING TRAFFIC LANE. AN SUV CAME DOWN THE HILL AND NEARLY BROADSIDED ME BEFORE I WAS ABLE TO GET MY CAR TURNED BACK DOWN THE HILL. (MY CAR WAS EQUIPPED WITH AGGRESSIVE SNOW TIRES AT THE TIME.) EVER SINCE THEN, IF I'M COMING HOME FROM WORK IN THE SNOW, I LEAVE MY CAR IN THE SHOPPING CENTER AT THE BOTTOM OF THE HILL AND CALL MY HUSBAND, WHO PICKS ME UP WITH HIS FORD BRONCO. # 2: ANTI-LOCK BRAKING. THE 2010 PRIUS'S AREN'T THE ONLY ONES WITH PROBLEMS; MINE DOES THE SAME THING. IF I'M BRAKING ON A BUMPY STRETCH OF ROAD OR OVER A MANHOLE COVER IN THE RAIN, THE CAR WILL CUT POWER TO THE BRAKES, CAUSING THE CAR TO FEEL LIKE IT'S SURGING FORWARD. AGAIN THIS PROBLEM IS MUCH WORSE IN THE SNOW. GOING DOWNHILL ON A SNOWY, SLIPPERY HILL THE ANTI-LOCK BRAKES REPEATEDLY CUT BRAKING POWER, WHICH ACTUALLY CAUSES THE CAR TO ACCELERATE TO UNSAFE SPEEDS. MY DEALER TELLS ME THAT THIS IS HOW THE CAR WORKS, AND NOTHING CAN BE DOME TO CORRECT IT. *TR

WHEN TRYING TO STOP IF I HIT THE POTHOLE THE CAR'S BRAKES JUST SEEM TO DISAPPEAR FOR A SECOND. ALMOST RAN OUT THROUGH STOP SIGN. THIS HAS HAPPENED A COUPLE OF TIMES SO I AM NOW VERY CAREFUL TO AVOID THE HOLE BY NEARLY RUNNING OFF THE RIGHT SIDE OF THE ROAD. NOW I HEAR THERE IS A RECALL FOR THE SAME THING WITH THE 2010 PRIUS. I'VE ALREADY HAD THE "FLOOR MAT" RECALL. THIS CONCERNS ME BECAUSE I WONDER IF IT IS REALLY THE FLOOR MATS OR THE RUN AWAY GAS PEDAL PROBLEM. I'M GOING ON VACATION AND SERIOUSLY CONSIDERING RENTING A CAR BECAUSE I'M ALMOST AFRAID TO DRIVE MY CAR. *TR

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.

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

Steering
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
