RECENTLY, I PERFORMED A ROUTINE FLUSH OF THE BRAKE FLUID ON MY TOYOTA PRIUS. WHEN I STARTED THE PRIUS AFTER COMPLETING THE BRAKE FLUID FLUSH, THERE WERE WARNING LIGHTS SHOWING ON THE DASHBOARD FOR THE BRAKES, THE TRACTION CONTROL SYSTEM, AND THE ANTI-LOCK BRAKE SYSTEM. THIS DIDN'T SURPRISE ME THAT THE CAR DETECTED AN ABNORMALITY DURING THE BRAKE BLEEDING OPERATION. WHAT DID SURPRISE ME IS THAT THE PRIUS COMPUTER INSTRUCTED THE FRONT BRAKES TO BECOME NON-OPERATIONAL THE TROUBLE CODE IN THE PRIUS COMPUTER AUTOMATICALLY DISABLED THE FRONT BRAKES BECAUSE THE COMPUTER WAS CONFUSED BY THE VARYING PRESSURES PRESENT IN THE BRAKE LINES DURING A ROUTINE BRAKE FLUID FLUSH. I DROVE TO A REPAIR SHOP WITH ONLY THE REAR BRAKES OPERATIONAL. AT THE REPAIR SHOP, A TECHNICIAN CLEARED THE TROUBLE CODES FOR THE BRAKE SYSTEM STORED IN THE ELECTRONIC CONTROL MODULE OF THE PRIUS. THE BRAKES WERE THEN COMPLETELY OPERATIONAL. I FIND IT UNCONSCIONABLE THAT THE CAR COULD DECIDE ON IT'S OWN TO DISABLE THE BRAKES, EVEN WHEN THE BRAKES WERE OTHERWISE FULLY FUNCTIONAL. PLEASE REQUIRE TOYOTA TO PROGRAM THEIR CONTROL MODULES TO ALLOW THE BRAKES TO FUNCTION WHEN TROUBLE CODES ARE ACTIVATED.

ODD BRAKING BEHAVIOR IN 2004 TOYOTA PRIUS. WHEN CAR IS IN ITS FIRST FEW MINUTES OF OPERATION AFTER SITTING OVERNIGHT, THIS ODD BEHAVIOR OCCURS: THE FIRST OR SECOND TIME I APPLY THE BRAKES, THEY GRAB AS THOUGH THE PEDAL HAS BEEN PRESSED VERY HARD. THE CAR LURCHES TO A STOP. I RELEASE THE BRAKE PEDAL TO GO FORWARD AGAIN, APPLYING PRESSURE TO THE ACCELERATOR PEDAL. THEN I APPLY PRESSURE TO THE BRAKE PEDAL AND THE GRABBING HAPPENS AGAIN. USUALLY BY THE THIRD BRAKING ACTION THE 'GRABBY' BEHAVIOR STOPS. THIS HAS NOT HAPPENED AT HIGH SPEEDS, PRESUMABLY BECAUSE THE CAR GETS IT 'OUT OF ITS SYSTEM' BY THE TIME IT IS WARMED UP. I USED TO BE A MECHANIC AND THIS IS DEFINITELY SOMETHING I HAVE NEVER FELT BEFORE, SUCH AS CONDENSATION ON THE DISC ROTORS. THIS HAS BEEN HAPPENING SINCE THE CAR WA NEW IN 2004. I WORKED AROUND IT.

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.

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
