IN NOVEMBER, 2013, THE VSC SYSTEM WARNING LIGHT AND SEVERAL OTHER LIGHTS ("ABS")CAME ON IN THE CAR. A WARNING NOISE REMAINS ON AT ALL TIMES SINCE THEN...THE SAME SOUND THAT COMES ON IF YOU FAIL TO FASTEN YOUR SEAT BELT. THE DEALERSHIP TESTED THE SYSTEM AND DETERMINED IT NEEDS A NEW BRAKE ACTUATOR PART WHICH WITH LABOR COMES TO OVER $2,000.00. I FILED COMPLAINTS WITH TOYOTA AND OTHER NATIONAL GROUPS TO NO AVAIL. I RECENTLY WAS NOTIFIED OF ANOTHER TOYOTA RECALL AND CAME ON THIS SITE AND DISCOVERED AN IDENTICAL INCIDENT (NHTSA ID NUMBER:10562656.) PLEASE INVESTIGATE THIS MATTER AND ADVISE OF THE FINDINGS AS IT APPARENTLY IS A GROWING ISSUE AND RISK EXPERIENCED AND DOCUMENTED BY OWNERS. *TR

I JUST BOUGHT THE CAR 2 WEEKS AGO (3/17/14) AND IT HAS BEEN DRIVEN FOR 500 MILES WITHOUT ANY INCIDENT. LAST NIGHT I PARKED IN MY USUAL SPOT ACROSS THE ROAD FROM MY HOUSE. ON THE MORNING OF SUNDAY (3/30/14) I WENT TO TURN ON MY CAR AND I NOTICE A P/S RED LIGHT CAME ON AND DID A QUICK SEARCH ON THE INTERNET AND REALIZED IT WAS MY POWER STEERING FAILING. DID A QUICK TEST, CONFIRMED THAT MY STEERING WHEEL WAS DIFFICULT TO TURN. I DID SOME FURTHER RESEARCH ON THE INTERNET AND REALIZE THIS IS A COMMON PROBLEM WITH HIGHLAND HYBRID AND THERE WAS ALREADY A NHTSA ACTION (PE06055) FILED PREVIOUSLY BUT HAD NO CONCLUSION. I WANT TO MAKE SURE THAT THIS PROBLEM WAS BROUGHT UP AGAIN, THAT IT HASN'T GONE AWAY, IT IS DANGEROUS AND I HAVE SEEN NUMEROUS WEB BLOG ABOUT THIS: HTTP://WWW.GREENHYBRID.COM/DISCUSS/F12/2006-HCH-LOST-POWER-STEERING-BRIEFLY-25044/ HTTP://ANSWERS.EDMUNDS.COM/QUESTION-POWER-STEERING-FAILURE-ON-2006-HIGHLANDER-HYBRID-9455.ASPX IT IS ABSURD THAT TOYOTA REFUSE TO DO ANYTHING ABOUT A BAD QUALITY PRODUCT THEY PRODUCE. IF THEY DON'T WANT TO RECALL, AT LEAST FIX THE ONE THAT ACTUALLY EXPERIENCE THE PROBLEM RATHER THEN HAVE PEOPLE SHELLING OUT THEIR MONEY (ON TOP OF WHAT THEY ALREADY PAID TO PURCHASE THE CAR) TO FIX A PROBLEM THAT TOYOTA CREATED IN THE OUTSET. *TR

IN OCTOBER 2013 I HAD A "CHECK VSC SYSTEM" WARNING LIGHT. UPON TAKING IT TO THE DEALERSHIP, THEY SAID IT WAS DUE TO THE BATTERY AND REPLACED IT AND THE WARNING LIGHT WENT AWAY. HOWEVER, OVER THE NEXT FEW MONTHS, WE STARTED NOTICING A "SQUEAKING" SOUND COMING FROM THE AREA UNDERNEATH THE FRONT OF THE CAR WHEN THE CAR WAS IN DRIVE BUT THE BRAKES WERE APPLIED. YESTERDAY, THE SAME "CHECK VSC SYSTEM" WARNING POPPED UP, ONLY NOW IT WAS ACCOMPANIED BY A NUMBER OF OTHER LIGHTS ON THE DASH, INCLUDING "ABS" "BRAKE" THE "TIRE PRESSURE (!)" AND ONE OTHER LIGHT ON THE LEFT SIDE TO THE UPPER RIGHT OF THE "READY" TEXT. THE DEALER HAS JUST TOLD ME THERE WERE TWO COMPUTER CODES, ONE IS C1241. THEY SAID THE PREVIOUS DEALER DID NOT DIG DEEP ENOUGH INTO THE ISSUE IN OCTOBER, AND THAT THE BRAKING SYSTEM WAS NOT GETTING ENOUGH PRESSURE. THE BRAKE ACTUATOR NEEDS REPLACEMENT, THE PART IS $1,800 AND WITH LABOR AND TAXES THE BILL COMES TO OVER $2,400. BASED ON OTHER RESEARCH I HAVE DONE TODAY THIS SEEMS TO BE A GROWING ISSUE THAT MANY OWNERS ARE FACING. *TR

I WAS TURNING RIGHT AT AN INTERSECTION WHEN A WOMAN WALKING HER DOG BEGAN CROSSING THE STREET. I SLAMMED ON THE BRAKES TO AVOID HER AND THE CAR SUDDENLY ACCELERATED SOUNDLESSLY FORWARD (CAR IS HYBRID BUT PRESSING ACCIDENTALLY ON THE GAS PEDAL WITH FORCE WOULD HAVE CAUSED REVVING NOISE) AND I COULD NOT CONTROL IT.. I RAN OVER THE WOMAN'S FOOT AND ALSO HER DOGS FEET. I DROVE THE CAR UP OVER A CURB WHICH RESULTING IN A FLAT TIRE TO GET THE CAR TO STOP. THERE WAS NO INJURY TO THE CAR OR MYSELF. THE WOMAN WAS TAKEN TO THE HOSPITAL BUT HAD NO BROKEN BONES. THE DOG HAD BRUISING AND DISCOMFORT BUT NO SERIOUS INJURIES EITHER. TOOK THE CAR TO A TOYOTA DEALERSHIP AND THEY COULD FIND NO ALERTS, WARNINGS, OR ANYTHING WRONG WITH IT THAT COULD HAVE CAUSED IT TO ACCELERATE UNINTENTIONALLY. *TR

THE CASE WAS STOPPED AND PLACED IN PARKING WHEN THE VEHICLE STARTED MOVING FORWARD AT ABOUT 3 MPH. I ALMOST HIT A CAR 5 FEET IN FRONT OF ME(AT THE TIME I PLACED THE HIGHLANDER IN PARKING GEAR) AND IT ENDED 6 INCHES AWAY FROM THE CAR IN THE FRONT. I HAD TO STEP ON THE BRAKE SHIFT GEARS FROM PARKING TO DRIVE. SHIFT AGAIN TO PARKING AND WHILE KEEPING THE BRAKES ON I PRESSED ON THE PARKING BRAKE AND TURNED THE CAR OFF. THERE WAS NO INCLINE IN THE STREET OR ANY DECLINE OBSERVABLE THAT COULD HAVE CAUSED THE ORIGINAL FAILURE. MY WIFE AND MY 1 YEAR OLD CHILD WERE INSIDE THE CAR WHEN THIS HAPPENED. *TR

AS I PULLED OUT OF THE PARKING LOT OF A HOTEL THE CHECK VCS SYSTEM, CHECK HYBRID SYSTEM, CHECK AWD SYSTEM WARNINGS BEGAN TO ILLUMINATE AND ALTERNATE. THE MASTER WARNING LIGHT, SLIP INDICATOR LIGHT, CHECK ENGINE WARNING LIGHT AND THE ELECTRONICALLY CONTROLLED BRAKE SYSTEM WARNING LIGHT WERE ALL ILLUMINATED AS WELL. THE CAR WOULD DRIVE, HOWEVER, THE POWER STEERING AND ABS WERE NOT WORKING. I WAS ABLE TO DRIVE THE CAR TO THE CLOSEST TOYOTA DEALERSHIP. I WAS ORIGINALLY TOLD THAT THE CAR SIMPLY NEEDED A NEW BATTERY. ONCE THE BATTERY WAS REPLACED, I WAS TOLD THAT THE ECU FOR THE ABS SYSTEM HAD DIED AND WOULD NEED TO BE REPLACED AT THE COST OF $2000. WHEN I MENTIONED THE RECALL AND THE FACT THAT THE SYMPTOMS WERE DIRECTLY IN LINE WITH THE RECALL NOTICE FOR THE IMP I WAS TOLD THAT WHILE MY VIN FELL UNDER THE BOJ RECALL, THE SPECIFIC SERIAL # OF MY IMP DID NOT. I WAS ALSO TOLD THAT THIS WAS NOT THE PROBLEM MY CAR WAS HAVING. WHEN I ASKED WHETHER THE SERIAL NUMBERS OF THE D1M RECALL WERE CHECKED I WAS TOLD THIS WAS AN "INTERIM RECALL" AND THAT THEY WERE NOT AUTHORIZED TO DO REPAIRS ON THIS ONE YET SO THEY COULDN'T CHECK. RESEARCH HAS INDICATED THAT AN IMP FAILURE CAN CAUSE AND ECU FAILURE. FURTHERMORE, AN ECU FAILURE WOULD NOT HAVE CAUSED THE SYSTEM TO GO INTO FAIL SAFE MODE AS IT DID. I HAVE A TOYOTA CASE #, BUT THEY HAVE TOLD ME THERE IS NOTHING THEY CAN DO. *JS

MY WIFE WAS DRIVING THE CAR HOME AFTER GROCERY SHOPPING AND THE CAR JUST QUIT. SHE COASTED TO THE SIDE OF THE ROAD AND CALLED ME. I ARRIVED AND TRIED TO START THE CAR WITH NO LUCK. FINALLY CALLED A TOW TRUCK AND HAD IT TOWED TO THE TOYOTA DEALER. THEY INSPECTED THE CAR ON TUESDAY (SEP 17,2013) AND SAID THE INVERTER WAS BAD AND THAT A REPLACEMENT WOULD BE $8,500. I ASKED THEM TO CHECK RECALLS ETC... WITH THE REGIONAL REP. THEY ARE AWAITING A SMALL PART TO SEE IF THAT WILL CAUSE THE INVERTER TO WORK PROPERLY. MY BIGGEST CONCERN WAS THE CAR JUST QUIT WITHOUT WARNING WHILE DRIVING DOWN THE ROAD! *TR

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.
