WHEN I GO OVER A BUMP OR UNEVEN SURFACE OR GRATE OR SLIPPERY SURFACE WHILE BRAKING IN MY 2006 TOYOTA PRIUS, THE ABS (ANTILOCK BRAKE SYSTEM) AND/OR VEHICLE STABILITY CONTROL/TRACTION CONTROL ACTIVATES. THE PROBLEM IS THAT WHEN THESE SYSTEMS DO SO, IT FEELS LIKE I LOSE ALL BRAKING POWER AND IT SEEMS AS THOUGH THE CAR ACCELERATES. IT IS MOST APPARENT WHEN IT IS WET OUT, BUT I'VE HAD THIS HAPPEN EVEN IN DRY CONDITIONS. TOYOTA DEALERSHIP SAYS THAT THIS IS NORMAL OPERATION FOR THE ABS, BUT THEY SEEM TO BE CORRECTING THIS SAME PROBLEM FOR 2010 PRIUSES THROUGH A SOFTWARE CHANGE--BUT NOT ANY OTHER YEAR MODELS. *TR

MY HUSBAND'S SUBURU FORESTER DOES NOT GIVE THIS UNSETTLING FEELING, AS IF LOSING CONTROL, WHEN IN ANTI-LOCK BRAKING MODE. THIS HAS BEEN OCCURRING SINCE I BOUGHT THE CAR, ON AN OCCASIONAL BASIS. I REPORTED IT TO MY TOYOTA CAR DEALER'S SERVICE DEPARTMENT BEFORE MY WARRANTY WAS UP AND WAS TOLD "THE ANTI-LOCK BRAKES ARE SUPPOSED TO DO THAT." I SUSPECT IT MAY BE RELATED TO THE REGENERATION OF THE ELECTRIC BATTERY WHILE BRAKING SINCE THIS IS A DIFFERENCE FROM OTHER VEHICLES. *TR

2006 TOYOTA PRIUS LOSES ALL TRACTION WHEN ENCOUNTERING CONDITIONS WHERE ONLY ONE WHEEL LOSES TRACTION. THIS FAILURE OCCURS ON ROADS WITH SAND ON THEM. MOST COMMONLY IT OCCURS WHEN ATTEMPTING TO TURN RIGHT AT AN INTERSECTION, FROM THE RIGHT OR TURN LANE. WHEN TO ACCELERATOR IS PRESSED, THE CAR STARTS TO MOVE, USUALLY A LITTLE WAY INTO THE INTERSECTION, AND THEN STALLS BECAUSE THE RIGHT FRONT WHEEL STARTS TO SLIP IN THE SAND ALONG THE CURB. THIS IS ESPECIALLY DANGEROUS WHEN EXECUTING A "RIGHT ON RED" TURN. THE CAR HAS MOVED PART WAY INTO THE INTERSECTION AND IS STALLED BY THE LACK OF ANY TRACTION. TOYOTA CALLS THIS "TRACTION CONTROL". I DON'T THINK THIS IS AN ACCURATE DESCRIPTION. IT'S REALLY COMPUTER CONTROLLED TRACTION LOSS. THE OCCURRENCE REPORTED IS ONLY THE LATEST. IT HAS BEEN GOING ON FOR ALMOST 4 YEARS. COMPLAINTS TO TOYOTA HAVE BEEN FRUITLESS, BECAUSE THEY SAY THE SYSTEM IS OPERATING WITHIN DESIGN LIMITS. I HAVE BEEN TOLD THAT THE SYSTEM WAS DESIGNED TO PREVENT OVER-REVVING OF ENGINE COMPONENTS AND STRESSING THEM. *TR

WHEN DRIVING ON ROADS THAT ARE CURVED, WHEN CHANGING LANES, OR ON STREETS THAT ARE WET, THE CAR FEELS UNBALANCED, AND REQUIRES A QUICK STEERING ADJUSTMENT TO REGAIN NORMAL OPERATION. INCIDENTS LIKE THESE OCCUR TOO FREQUENTLY, AT LEAST THREE TIMES A WEEK, AND WHEN THEY OCCUR, THE VEHICLE'S RED SKID LIGHT IS ILLUMINATED (I SUPPOSE IT IS RELATED TO THIS MODEL'S ANTI-SKID AND/OR TRACTION CONTROL FEATURE THAT WAS NOT STANDARD EQUIPMENT). TRACTION CONTROL WAS AN OPTIONAL FEATURE THAT THE DEALERSHIPS OFFERED IN MORE EXPENSIVE PACKAGES OF THE 2006 PRIUS BUNDLED TOGETHER WITH OTHER ITEMS THAT WERE NOT RELATED TO DRIVING SAFETY, WHICH MADE THE PACKAGES UNNECESSARILY EXPENSIVE, AND WAS A FACTOR IN MY DECISION TO NOT OPT FOR THIS UPGRADE. HOWEVER, GIVEN THE FREQUENCY OF OCCURRENCE, I FELT THE NEED TO REPORT THIS IN CASE OTHER DRIVERS ARE EXPERIENCING SIMILAR ISSUES. THE DATE I HAVE SELECTED CORRESPONDS TO THE PURCHASE DATE OF THE VEHICLE, NOT TO ANY PARTICULAR INCIDENT OR ACCIDENT, AS THIS IS A RECURRING PROBLEM. FYI, TIRES, BRAKES, STEERING, AND ALIGNMENT HAVE ALL BEEN CHECKED AND MAINTAINED AS PER TOYOTA'S SUGGESTED GUIDELINES. *TR

OVER THE PAST 1 1/2 YEARS I'VE TAKEN MY PRIUS TO THE TOYOTA SERVICE WITH CONCERN OVER MY BRAKING SYSTEM THREE TIMES. TWICE THE HEAD OF SERVICE MECHANICS HAS DRIVEN WITH ME SEEING NOTHING UNUSUAL, THE THIRD TIME THE SERVICE MANAGER TOOK THE CAR OUT WITH ME. THEY ALL VOWED NOTHING WAS WRONG. THE REASON I'VE BEEN SO CONCERNED WAS DUE TO THE FACT THAT THE BRAKING SYSTEM DIDN'T RESPOND FAST ENOUGH AND MORE OFTEN THAN NOT, WITH WET PAVEMENT OR RAINING, PRESSING THE BRAKES WITH AUTHORITY, THE CAR WILL GO INTO A SLIGHT SKID WITH THE DASH SKID LIGHT COMING ON. THIS ENTIRE SENARIO HAS CAUSED ME TO BE OVERLY CAUTIOUS WHEN BRAKING ANYTIME AND IN ANY SITUATION. IF A QUICK ACTION IS NEEDED FOR SPEEDY BRAKING I QUESTION WHAT WOULD HAPPEN. IT APPEARS THE PEOPLE AT TOYOTA HAVE JUST TRIED TO APPEASE ME NOT BELIEVING NOR UNDERSTANDING WHAT'S BEEN IN ERROR. I DON'T FEEL SO INADEQUATE NOW THAT ALL THE CURRENT INFORMATION HAS COME TO LIGHT. WAS BEGINNING TO THINK I WAS THE COMPLAINER WITHOUT CAUSE. I LOVE MY CAR - BUT AM NOW EVEN MORE HESITANT ABOUT IT'S SAFETY. MUST ADMIT, I'M FAR MORE CAREFUL THAN EVER, BEING ON THE LOOKOUT FOR POSSIBLE BRAKING SITUATIONS IN ADVANCE. *CN

1. BRAKES ON MY 2006 PRIUS MOMENTARILY FAILED TO RESPOND, AFTER A 1 - 2 SEC DELAY THEY ACTIVATED. AT SAME TIME,THE TRACTION LIGHT FLASHES, BUT THE CAR IS NOT LOSING TRACTION. THIS HAPPENED 4 X, ONE ALMOST RESULTED IN A CRASH. IT IS MORE LIKELY TO HAPPEN WHEN BRAKING WHILE GOING OVER A BUMP IN THE ROAD. THERE HAVE BEEN OTHER TIMES WHEN THE TRACTION LIGHT FLASHES ON UNEXPECTEDLY, BUT EFFECT ON BRAKES IS UNKNOWN: NOT BRAKING THEN. 3 DIFFERENT TOYOTA DEALERS TOLD ME THEY COULDN'T FIND ANYTHING WRONG. AT ONE DEALER, I WENT FOR A TEST DRIVE WITH A MECHANIC. DURING THE TEST DRIVE, I WAS ABLE TO MAKE THE TRACTION LIGHT GO ON WHEN THERE WAS NO LOSS OF TRACTION. THE INVOICE STATED "TEST DROVE AND CHECKED OPERATIONS. AT THIS TIME COULD NOT DUPLICATE CUSTOMER'S CONCERNS." I WROTE ON THE INVOICE "I WAS ABLE TO MAKE THE TRACTION LIGHT GO ON WHEN THERE WAS NO LOSS OF TRACTION. I AM NOT SATISFIED THAT THE PROBLEM HAS BEEN FOUND AND REPAIRED." & ON THE SIGNATURE LINE "NOT SATISFIED, (SIGNATURE)" I WANTED THEM TO CHANGE THE COMPUTER, BUT THEY SAID IF THEY COULDN'T DUPLICATE THE PROBLEM, THEY COULDN'T CHANGE THE COMPUTER. I INSISTED THAT THEY REPLACE ONE COMPONENT, AND IF THE PROBLEM DIDN'T REOCCUR, I'D KNOW THEY FOUND THE SOLUTION. THEY BLED THE BRAKES, WHICH WAS UNLIKELY TO BE CAUSE OF THE PROBLEM. WHEN I WENT TO PICK UP MY INVOICE UP 2ND TIME, THE COPY ON WHICH I HAD WRITTEN MY COMMENTS WAS RETURNED TO ME, AND A FRESHLY PRINTED COPY- WITHOUT MY COMMENTS - WAS GIVEN TO ME & KEPT FOR THEIR RECORDS. 2. SAME CAR: HEADLIGHT GO OUT AT UNEXPECTED TIMES. 2 TOYOTA DEALERS TOLD ME THAT THE BULB WOULD COST $300, AND INSTALLATION WOULD BE WELL OVER $100 BECAUSE THEY "HAD TO TAKE OFF THE BUMPER TO CHANGE THE BULB!" I REPLACED THE BULB MYSELF (WITHOUT TAKING OFF THE BUMPER) BUT NOW, 9 MONTHS LATER, IT IS STARTING TO GO AGAIN. TOYOTA SENT A LETTER SAYING IT WAS HOW HID BULBS BURNED OUT & NOT A PBLM W/ CONTROLLER. IF TRUE, HOW IS IT THAT NEW BULB IS ALSO BURNING OUT? *TR

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

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.
