I OWN A 2005 TOYOTA PRIUS. I PURCHASED IT IN MARCH 2005. LAST WEEK, MY MULTIFUNCTIONAL DISPLAY (MFD) CEASED TO OPERATE CORRECTLY. THE MFD INITIALIZED TO THE MPG SCREEN BUT HAD UNUSUAL COLORS. I ATTEMPTED TO CHANGE THE DISPLAY SCREEN BY SELECTING THE AUDIO, CLIMATE, DISPLAY, AND INFO BUTTONS BUT TO NO AVAIL. THE SCREEN WOULD GO BLANK AND THEN SHOW THE ?PRIUS HYBRID? INITIALIZING SCREEN AND THEN RETURN TO THE MPG SCREEN. AS I WAS NEARING MY 80K SERVICE, I CONTACTED MY DEALER AND REPORTED THE PROBLEM. THEY DIAGNOSED THE MFD AS BEING UNSERVICEABLE THAT NEXT SATURDAY. THE SERVICE REPRESENTATIVE MADE THE COMMENT THAT IT WAS COMMON FOR THE MFD TO GO BAD. TO REPLACE THE MFD WITH A NEW ONE, IT IS $4,000.00 PLUS INSTALLATION. THAT IS 19% OF THE COST OF THE VEHICLE WHEN IT WAS BRAND NEW! I BEGAN RESEARCHING AND FOUND THAT TOYOTA HAD ISSUED A TECHNICAL SERVICE BULLETIN ON 10 JANUARY 2005 TITLE: MULTI-DISPLAY FUNCTIONS ARE INOPERATIVE; TSB# EL002-05 WHICH IDENTIFIED ISSUES WITH THE MFD. ALSO IN BROWSING THE WEB SPECIFICALLY WWW.PRIUSCHAT.COM AND HTTP://AUTOS.GROUPS.YAHOO.COM/GROUP/PRIUS-2G/ AND SAW THAT I WAS NOT THE ONLY ONE WITH THIS PROBLEM. ONE ELECTRONICALLY GIFTED PERSON DISASSEMBLED HIS MFD AND DIAGNOSED THE PROBLEM AS IMPROPER SOLDERING ON THE CIRCUIT CARD (SEE HTTP://TECHNO-FANDOM.ORG/~HOBBIT/CARS/MFD/COMPARE.HTML ). IT SEEMS THAT TOYOTA CORPORATION WAS AWARE OF THE PROBLEM AND WERE NOT DISCLOSING IT HOPING THAT THE FAULTY MFD?S WOULD NOT BE DISCOVERED UNTIL THE VEHICLES EXCEEDED THE 3 YEAR 36,000 WARRANTY. I KNOW I AM OUTSIDE THE MILEAGE WARRANTY, HOWEVER, I AM JUST PASSED THE 3 YEAR WINDOW. I PURCHASED AND USE MY CAR AS A COMMUTER VEHICLE DRIVING ALMOST 100 MILES PER DAY. AS A MAINTENANCE OFFICER IN THE US ARMY, I KNOW THERE ARE COMPONENTS THAT ARE MILEAGE DEPENDENT (ENGINES, TRANSMISSIONS, DIFFERENTIALS) BUT THIS IS NOT ONE OF THEM. ELECTRICAL COMPONENTS ARE BUILT TO LAST THE MAJORITY OF VEHICLES LIFE, NOT JUST UNTIL THE WARRANTY EXPIRES. *TR

TOYOTA PRIUS 2005 FAILING BRAKE SYSTEM- FOR THE SECOND TIME (THE FIRST INCIDENT WAS ON 27-JUN-2008) MY BRAKES WERE NOT FUNCTIONING PROPERLY. THE FIRST TIME THE TOYOTA DEALERSHIP "RECALIBRATED THE COMPUTER" AND COULD NOT TELL ME WHY IS FAILED OR THAT IT WOULD NOT HAPPEN AGAIN. THE SECOND OCCASION, YESTERDAY, I ACTUALLY REARENDED ANOTHER CAR. NO DAMAGE OTHER THAN A COMPLAINT OF POSSIBLE WHIPLASH AND A WARNING THAT I MAY HEAR FROM HIM IN A FEW DAYS. THE DEALER JUST CALLED ME THIS AFTERNOON TO TELL ME THAT NOW THEY ARE "REPLACING THE COMPUTER." DOES THIS HAPPEN TO PRIUS'S.

Nov 14, 2012

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.

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.

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

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
