I HAVE HAD TO REPLACE THE BRAKE ACTUATOR ON MY 2006 TOYOTA HIGHLANDER HYBRID 3 TIMES SINCE 2014. REPLACING THIS PART IS A $2500 - $3000 REPAIR. THE FIRST TIME, WE PAID OUT OF POCKET. THE SECOND TIME, I WAS TOLD I WOULD HAVE TO PAY OUT OF POCKET AND I DECLINED. PARKED THE VEHICLE FOR ABOUT A YEAR AND THEN RECEIVED NOTICE FROM TOYOTA THAT THE PART WAS BEING OFFERED AN EXTENDED WARRANTY UNDER LETTER ZG1. AT THAT POINT, I HAD THE PART REPLACED UNDER THE EXTENDED WARRANTY. NOW THE PART HAS FAILED AGAIN. THIS IS A VERY SERIOUS ISSUE AS IT CONTROLS THE ABS BRAKING SYSTEM AND FAILURE CAN HAVE DEVASTATING CONSEQUENCES. I THINK TOYOTA RECOGNIZED THE ISSUE, MADE ADJUSTMENTS, BUT DID NOT MAKE PROPER ADJUSTMENTS AND STILL HAS ISSUES WITH THIS PART. PARTICULARLY - THIS ISSUE MAY BE RELATED TO THE FACT THAT THE HYBRID VEHICLES RELY ON THE BRAKING SYSTEM TO REGENERATE THE BATTERY.

WHILE ATTEMPTING TO MAKE A STOP AT AN INTERSECTION DURING CITY DRIVING THE BRAKE PEDAL BECAME VERY HARD TO PRESS DOWN AND SEVERAL WARNING LIGHTS CAME ON MY VEHICLE DASHBOARD. AT FIRST, THE PROBLEM WAS INTERMITTENT BUT PROGRESSIVELY GOT WORST OVER CONTINUED DRIVING. I TOOK MY VEHICLE TO MY LOCAL TOYOTA DEALER FOR INSPECTION. THE SERVICE MANAGER INFORMED ME THAT I HAD A PROBLEM WITH THE ABS BRAKE SYSTEM MODULE AND THE REPAIR WAS ABOUT $2,600.00. I PARKED THE VEHICLE BECAUSE IT WAS NO LONGER SAFE TO DRIVE AND TO MANY CLOSE CALLS. LATER I FOUND OUT THAT THIS 2006 TOYOTA HIGHLANDER HYBRID AND SEVERAL PROCEEDING MODEL YEARS HAD A VERY EXTENSIVE CONSUMER COMPLAINT NUMBER FOR THIS VERY SAME ABS BRAKE SYSTEM CONCERN. I CONTACTED THE SERVICE MANAGER AT THE SAME LOCAL TOYOTA DEALERSHIP ABOUT A WARRANTY AT WHICH TIME THE SERVICE MANAGER INFORMED ME THAT MY WARRANTY EXPIRED WHICH I NEVER WAS INFORMED. IT SEEMS TO ME PERSONALLY THIS IS HOW THE AIR BAG SAFETY PROBLEM WAS OVER LOOKED ON THESE VEHICLES UNTIL CONSUMERS LOST THEIR LIVES ON FAULTY CONSUMER PRODUCTS THAT GOT PROGRESSIVELY WORST OVER TIME. SEVERAL OF THE OTHER IMPORT MANUFACTURE HAVE OFFERED RECALLS ON THE VERY SAME ABS SYSTEM BRAKE CONCERN. TOYOTA HAS YET TO OFFER A RECALL SEVERAL MODEL YEARS INTO THIS SAFETY CONCERN WITH THE ABS BRAKE SYSTEM. IF WE AS CONSUMERS CAN'T STOP OUR VEHICLES WHILE DRIVING ON THE CITY STREETS OR HIGHWAYS ACCIDENTS HAPPEN AND PEOPLE DIE. THIS SAFETY CONCERN HAS GONE ON LONG ENOUGH WITH THOUSANDS OF COMPLAINTS OVER THE YEARS FOR THE SAME ABS BRAKE SYSTEM CONCERN. THERE MUST BE A MUCH BETTER JOB AT PROTECTING THE CONSUMER SAFETY FROM CONTINUED SAFETY CONCERNS NOT BEING ADDRESSED BY TOYOTA. ALL THE OTHER IMPORT MANUFACTURES HAVE STEP UP WITH RECALLS, WHATS TAKING TOYOTA MANUFACTURES SO LONG AFTER YEARS OF THE SAME SAFETY CONCERNS. PLEASE HELP US WITH THIS ABS BRAKE SYSTEM CONCERN.

I PURCHASED THE VEHICLE USED IN AUGUST 2018. IN JANUARY, WARNING LIGHTS INDICATED A 'VSC SYSTEM' PROBLEM. THE EVENT OCCURRED WHILE I WAS DRIVING. I RESEARCHED CAR REPAIR WEBSITES AND FORUMS, AND DISCOVERED THAT THIS IS OFTEN A SIMPLE PROBLEM WITH A SENSOR FOR THE FUEL DOOR, OR A LINKAGE IN THE ACCELERATOR ASSEMBLY. I FOLLOWED INSTRUCTIONS, AND THE LIGHT TURNED OFF. OVER THE PAST SIX WEEKS, THE LIGHTS HAVE RETURNED, USUALLY IN ASSOCIATION WITH REFUELING THE VEHICLE. I TOOK THE VEHICLE TO A DEALER TODAY, AND WAS INFORMED THAT AN ABS ACTUATOR WAS FAILING. THE PART IS $1700 FROM TOYOTA, WITH LABOR TOTALING $600. FURTHER RESEARCH REVEALED THE PROBLEM WAS WIDESPREAD, BUT THE ONLY REMEDY WAS A 'WARRANTY ENHANCEMENT' THAT HAS ALREADY EXPIRED. I CANNOT AFFORD THIS REPAIR, AND I WAS NOT INFORMED OF THIS ISSUE AT PURCHASE. BECAUSE THIS ISSUE WAS CRITICAL FOR VEHICLE SAFETY, I FELT THE NEED TO ALERT THE NHTSA TO A CONTINUING PROBLEM.

INTERMITTENTLY, WHILE DRIVING DOWN THE ROAD, ALL OF THE DASH LIGHTS COME ON, THERE IS A HIGH BEEPING SOUND, AND THE BRAKES STOPPED FUNCTIONING PROPERLY. THE BRAKES EITHER NEED TO BE MATCHED WITH EXTREME FORCE OR THE BRAKES WILL SLAM BY BARELY TOUCHING THE BRAKE PEDAL. TOYOTA ACKNOWLEDGES THAT THIS IS AN ISSUE AND OFFERED A WARRANTY EXTENSION TO OWNERS OF THIS VEHICLE. I PURCHASED THE VEHICLE AFTER THE EXTENSION WAS OFFERED AND HAVEN'T HAD ISSUES UNTIL RECENTLY. I AM CONCERNED FOR NOT ONLY MY SAFETY BUT THE SAFETY OF MY FAMILY. I HAVE BEEN A TOYOTA FAN FOR ALL OF MY ADULT LIFE. HOWEVER, AFTER DEALING WITH THIS ISSUE AND BEING QUOTED $2000 TO FIX IT, I WOULD OFFER ADVICE TO ANYBODY OR NOT TO BUY A TOYOTA OR AT LEAST NOT A TOYOTA HYBRID. BUYER AND DRIVER BEWARE!

WHILE DRIVING ON A RESIDENTIAL ROAD THE BRAKE SYSTEM FAILED TO PROPERLY STOP THE CAR. THIS ISSUE FIRST HAPPENED IN JANUARY 2017. AT THAT TIME I TOOK THE CAR IN AND HAD THE BRAKE ACTUATOR ASSEMBLY REPLACED UNDER A LIMITED SERVICE RECALL BY TOYOTA AND THE REPLACEMENT ACTUATOR ASSEMBLY ALSO FAILED WITHIN 18 MONTHS. WHILE DRIVING THROUGH A RESIDENTIAL AREA THE BRAKES AGAIN FAILED TO STOP THE CAR, MAKING A GRINDING NOISE AND JERKING TO A HALT AFTER PRESSURE APPLIED TO THE BRAKE PEDAL. BECAUSE THE ACTUATOR ASSEMBLY WAS REPLACED UNDER THE LIMITED SERVICE RECALL TOYOTA DENIES ANY CULPABILITY IN THE FAILURE OF THE REPLACEMENT PART AND REFUSES TO OFFER FURTHER ASSISTANCE.

DASHBOARD WARNING LIGHTS CAME ON ALL AT THE SAME TIME AND STAYED ON. WENT TO DIAGNOSE REPAIR AND THEY SAID IT NEEDS A NEW BRAKE ACTUATOR. UPON INVESTIGATING, I SEE THAT TOYOTA EXTENDED THE WARRANTY FOR 10 YEARS BUT IT EXPIRED ON DEC 31 2017. UPON REFLECTION, WE HAVE FELT THE BRAKES OCCASIONALLY BECOME VERY STIFF AND HARD TO STOP THE VEHICLE WHILE IN MOTION. THE MECHANIC SAYS IT IS BECAUSE OF THE ACTUATOR ISSUE. I FEEL THIS SAFETY ISSUE, ALBEIT RATHER OLD, IS A KNOWN ISSUE TO TOYOTA AND THEY SHOULD PROVIDE SOME RECOURSE FOR THE REPAIR. I HAVE INCLUDED THE DIAGNOSTIC SHOWING DIAGNOSTIC CODES AND MECHANIC EVALUATION.

PE11005 · Hybrid Inverter Failure - Vehicle Stall

Opened Feb 15, 2011 · Closed Jul 20, 2011

Status: closed (inferred from source dates) · Hybrid Propulsion System: Inverter

In a June 29, 2011 letter to NHTSA, Toyota submitted a Defect Information Report regarding a safety recall of certain Toyota Highlander Hybrid and Lexus RX400h vehicles to address a defect condition with the hybrid inverter assembly (NHTSA Recall No. 11V-342).Toyota's letter identified a defect related to inadequately soldered transistors on the Intelligent Power Module (IPM) of some of the subject vehicles that could result in sudden loss of power while driving.Toyota's remedy procedure instructs dealers to inspect the hybrid inverter production number to determine if the inverter contains suspect transistors.If so, the dealer will replace the IPM.The recall covers approximately 45,528 model year (MY) 2006 and 2007 Toyota Highlander Hybrid vehicles manufactured from February 16, 2005 through August 29, 2006 and approximately 36,745 MY 2006 and 2007 Lexus RX400h vehicles manufactured from February 23, 2005 through August 30, 2006.This Preliminary Evaluation is closed.

RQ10003 · Unintended And Uncontrolled Acceleration

Opened Feb 16, 2010 · Closed Mar 1, 2011

Status: closed (inferred from source dates) · Electrical System:software; Vehicle Speed Control:accelerator Pedal

On February 16, 2010, NHTSA's Office of Defects Investigation (ODI) opened RQ10-003 to determine whether the scope of prior Toyota recalls relating to potential unintended acceleration were sufficiently broad, including, among others, Toyota recalls 07E-082, 09V-388, 10V-017, and 10V-023.NHTSA also requested information regarding potential electronic causes of unintended acceleration in Toyota and Lexus vehicles.I. Pedal Interference from Floor mats, Carpet Covers and Plastic Pads in Carpets.During the RQ10-003 investigation, ODI reviewed a large volume of documents to assess whether additional vehicles should be recalled.Following the agency's analysis, NHTSA requested that Toyota recall additional vehicles.Toyota complied with the agency's request.The details of these recalls are set forth more fully in Toyota's reports to NHTSA pursuant to 49 CFR Part 573.These recalls are as follows:Recall 11V-112: (1) model year (MY) 2004-2006 Toyota Highlander and Highlander Hybrid; and, (2) MY 2004-2007 Lexus RX330,RX350, and RX400h (hybrid model). The total estimated population under this recall is 769,379 vehicles.This recall remedies potential accelerator pedal entrapment caused by a loose floor carpet cover (trim panel). Recall 11V-113: (1) MY 2003-2009 through 2009 Toyota 4Runner; (2) MY 2006-2010 Toyota RAV4; and, (3) MY 2008-2011 Lexus LX570.The total estimated population under this recall is 1,381,000 vehicles.This recall supplements recall 09V-388 and remedies potential accelerator pedal entrapment by an unsecured floor mat.Recall 11V-115: (1) MY 2006-2007 Lexus GS300 (all wheel drive vehicles); and, (2) MY 2006-2007 Lexus GS350 (all wheel drive vehicles). The total estimated population under this recall is 19,647 vehicles.This recall remedies potential accelerator pedal entrapment caused by inadequate clearance between the pedal linkage and a plastic pad embedded in the vehicle's carpet.II. Potential Electronic Causes of Unintended Acceleration.After NHTSA opened RQ10-003, NHTSA launched a ten-month study of potential electronic causes of unintended acceleration in Toyota vehicles.NHTSA launched the study in the spring of 2010 in light of concerns aired in Congressional hearings.NHTSA enlisted engineers at the National Aeronautics and Space Administration (NASA) with expertise in areas such as computer controlled electronic systems, electromagnetic interference and software integrity to assess whether electronic systems or electromagnetic interference played a role in incidents of unintended acceleration in Toyota vehicles.That study has concluded.Two reports are associated with the study and are available on NHTSA's website.NASA's report is entitled Technical Support to the National Highway Traffic Safety Administration (NHTSA) on the Reported Toyota Motor Corporation (TMC) Unintended Acceleration (UA) Investigation, NESC Assessment No. TI-10-00618 (Jan. 18, 2011).NHTSA's report is entitled Technical Assessment of Toyota Electronic Throttle Control (ETC) Systems (Feb. 2011).Both reports should be read in conjunction with each other. As stated in its report, NASA did not find an electronic cause of large throttle openings that can result in unintended acceleration incidents. NHTSA did not find a vehicle-based cause of unintended acceleration incidents other than the physical pedal interference causes that are being addressed by Toyota's recalls. This RQ is closed.
