I FOUND SOME INFO IN A FORUM WHERE MULTIPLE PEOPLE HAVE THE SAME COMPLAINTS ABOUT LEAKING AROUND THE AXLE. I WAS INFORMED THAT THE RIGHT AXLE SEAL NEEDS REPLACEMENT WHEN I TOOK MY VEHICLE TO THE DEALERSHIP FOR A MULTI-POINT INSPECTION. I'M NOT SURE IF THIS IS SOMETHING THAT HAPPENS OVER TIME BUT IT SEEMS LIKE IT'S HAPPENED TO OTHERS WHO HAVE NOTICED IT BEFORE THE WARRANTY EXPIRATION AND IT WAS COVERED UNDER THE POWERTRAIN WARRANTY. I PURCHASED AN EXTENDED WARRANTY BUT IT HAS EXPIRED AND I WAS NEVER TOLD ABOUT THIS ISSUE WHILE MY VEHICLE WAS UNDER WARRANTY.

WHILE DRIVING ON A MAJOR HIGHWAY AND IN THE FAST LANE GOING APPROXIMATELY 75/80 MPH MY 2006 TOYOTA HIGHLANDER HYBRID DIED AND FAILED TO DRIVE. THE PANEL ON THE DASH HAD A RED ! EXCLAMATION POINT, AND SAID CHECK HYBRID SYSTEM AND CHECK VSC SYSTEM. I WAS ABLE TO NAVIGATE MY VEHICLE TO THE RIGHT BREAKDOWN SHOULDER TO CALL FOR A TOW. TRIED TO START MY VEHICLE SEVERAL TIMES AND IT WOULD NOT START, BUT THE HAZARD LIGHTS AND INSTRUMENT PANEL CONTINUED TO LIGHT GIVING EVIDENCE MY NEW 12V BATTERY WAS FUNCTIONING PROPERLY. CALLED TOYOTA MOTOR USA AND ASKED WHAT RECALLS THEY HAVE LISTED FOR MY VEHICLE AND THEY ASKED FOR MY VIN. THEY TOLD ME THE ELECTRICAL INVERTER ASSEMBLY WAS COVERED FOR MY VIN. THEY GAVE ME THE NUMBER OF A TOW COMPANY TO CALL AND TOLD ME IT WAS COVERED BY TOYOTA AND I'D HAVE A RENTAL WAITING FOR ME. I HAD IT TOWED TO MY LOCAL DEALERSHIP AS DIRECTED, THEY FIXED SEVERAL OTHER RECALL ISSUES BUT NOT THIS ONE, SO WHEN I DROVE OFF THE LOT THE CAR DIED AGAIN. I MANAGED TO START THE VEHICLE AND DRIVE IT BACK ACROSS THE HIGHWAY INTO THE DEALERSHIP. AFTER SPEAKING WITH TOYOTA CORPORATION USA AGAIN, THEY APOLOGIZED AND SAID THEY MISINFORMED ME AND THAT MY VEHICLE WAS NOT PART OF THAT RECALL. HOWEVER, THEY PAID FOR MY TOW AND FOR MY RENTAL FOR 5 DAYS (THUS FAR). MY CASE NUMBER GIVEN FROM TOYOTA CORP IS 1607053248. I READ ONLINE THERE IS A CLASS ACTION SUIT REGARDING THIS ISSUE. KARL AND IRINA GAAL VS. TOYOTA MOTOR SALES, U.S.A., INC., A CALIFORNIA CORPORATION. VIA ATTY MIKE ARIAS. TOYOTA'S CUSTOMER EXPERIENCE HAS PUT IN A REQUEST FOR ME TO SPEAK WITH A SUPERVISOR AND THE TOYOTA DEALERSHIP'S GM IN MY AREA IS ALSO WORKING ON THIS ISSUE AS IT'S STILL PENDING.

MY WIFE AND I WERE TRAVELLING ON I-95 (SOUTHBOUND) TOWARDS RICHMOND, VA. MY WIFE WAS THE DRIVER. WE WERE STEADILY TRAVELLING AT A SPEED... BETWEEN 65 AND 70 IN THE LEFT LANE (REQUIRED SPEED LIMIT). ALL OF A SUDDEN, WITH NO WARNING, THE PANEL LIGHTS STARTED BLINKING AND THE POWER TO THE CAR WAS SHUT OFF. MY WIFE WAS SCREAMING BECAUSE SHE WAS NOT ABLE TO CONTROL OR EFFECTIVELY APPLY BRAKES. SHE TRIED AND PULLED CAR OFF THE ROAD BARELY AND WE PUSHED IT OFF TO A SAFE SIDE. THIS COULD HAVE RESULTED IN A SERIOUS ACCIDENT IF WE WERE TRAVELLING IN THE MIDDLE LANE. THE CAR WAS LEFT OVERNIGHT AND TOWED TO TOYOTA DEALER. THE DEALER CALLED BACK AND GAVE A QUOTE OF $10000 BECAUSE THE HYBRID INVERTER HAVE TO REPLACED. I MENTIONED THE RECALL ON THE INVERTER. THE DEALER SAID THE RECALL DOES NOT COVER MY ISSUE. THERE IS A RECALL ON YOUR WEBSITE -WHAT ACTION OR RECOURSE DO I HAVE. THE ORIGINAL OWNER OF THE CAR REPLACED THE INVERTER AT 16200 MILES. EVIDENTLY ALL THE 2006 INVERTERS ARE DEFECTIVE. MY QUESTION IS THIS ---WHY YOUR DEPARTMENT IS TOYOTA TO GET AWAY WITH SUCH A SERIOUS DEFECT?

THERE WAS FIRE IN THE INVERTER ASSEMBLY. THE WIRING HARNESS FOR THE INVERTER AND THE TRANSMISSION WERE COMPLETELY COOKED AND MELTED. THE PROFESSIONAL OPINION OF A TOYOTA NATIONAL ENGINEER IS THAT THE GENERATOR IN THE TRANS AXLE SURGED AND CAUSED A FIRE MELTING THE COMPONENTS. HOW CAN THIS GO UN-INVESTIGATED WITH SO MANY OF THESE VEHICLES ON THE ROAD. MY FAMILY AND I COULD HAVE BEEN BURNED ALIVE OR IN A FATAL CRASH DUE TO THIS COMPLETELY UNSAFE SYSTEM. HOW CAN TOYOTA CONTINUE TO SAY THEY ARE ALL ABOUT SAFETY WHEN THEY WILL NOT DO ANYTHING ABOUT ISSUES LIKE THIS. THEY HAVE SENT ME A $16,000 BILL FOR THIS ISSUE THAT IS COMPLETELY A PRODUCT OF THEIR POOR AND UNSAFE VEHICLE. *TR

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

MY SON WAS DRIVING AND THE VEHICLE STOPPED ON HIM IN THE MIDDLE OF THE ROAD WITH NO WARNING OR POWER STEERING. VEHICLE HAD TO BE TOWED TO THE DEALERSHIP. WAS INFORMED BY THE DEALERSHIP THAT THE HYBRID GENERATOR HAD SHORTED AND NEEDED $7,300.00 WORTH OF REPAIRS. I AM VERY CONCERNED THAT THIS VEHICLE IS DANGEROUS, IF HE WAS ON A VERY BUSY ROAD AND THIS VEHICLE WERE TO HAVE STOPPED ON HIM AS SUDDENLY AS IT DID THAT DAY HE COULD OF POSSIBLY BEEN REAR-ENDED AND SERIOUSLY INJURED.

AS I ACCELERATED FROM A STOP AT A SIDE STREET TO ENTER HIGHWAY TRAFFIC, I WAS NEARLY REAR ENDED BY A LARGE TRUCK WHEN THE HH INVERTER FAILED. THE CAR SIMPLY SUDDENLY FAILED TO RESPOND WITH NO ADVANCE WARNING. SEVERAL DASHBOARD SYMBOLS LIT UP, INCLUDING CHECK HYBRID SYSTEM,'AND I WAS ONLY ABLE TO STEER TO SIDE OF THE ROAD. IT WOULD NOT RESTART AND WAS TOWED TO THE DEALER. THE DEALER CHECKED FOR RECALLS AND SAID THERE WERE NONE. I MENTIONED THE JUNE 2011 NOTICE WE'D RECEIVED, AND THAT WE WERE TOLD THAT THE PART WOULD NOT BE AVAILABLE UNTIL JAN. 2012. WE DID NOT RECEIVE MORE INFORMATION FROM TOYOTA AND CALLED THE DEALER IN JAN. FOR AN APPOINTMENT. AFTER A BRIEF INSPECTION, WE WERE TOLD THE PART WAS NOT DEFECTIVE AND NO REPLACEMENT NECESSARY.' WE HAD BEEN EXTRA CAUTIOUS AND LIMITED THE USE OF OUR HH FOR MONTHS, AND WERE DISAPPOINTED THAT THERE WAS NO EFFORT TO EXAMINE THE PART EARLIER OR VERIFY THE CONDITIONS OF USE OF THE VEHICLE. AFTER THE CAR WAS TOWED IN APRIL 2012, THE DEALER SAID WE NEEDED A PART, WHICH THEY ORDERED AND INSTALLED AT NO COST TO US WITHIN A FEW DAYS. THE MANAGER SAID THAT IT WAS A VERY EXPENSIVE PART, TOOK A LONG TIME TO INSTALL, AND THAT WE WERE "LUCKY TO HAVE THE WARRANTY."' THERE WAS NO MENTION OF THE INVERTER RECALL BUT THE INVOICE INDICATED THAT THERE WAS A "BOJ RECALL." THERE MAY HAVE BEEN AN EARLIER CLUE: ON DEC. 1, 2011 THE SAME DASHBOARD INDICATORS (CHECK HYBRID SYSTEM AND VRC) LIT UP IN THE MORNING WHEN I WENT TO START IT AND COULDN'T. WE ASKED DEALER ABOUT RECALLS, MENTIONED THE UPCOMING SCHEDULED NOTIFICATION (JAN. 2012), BUT WERE TOLD THERE WERE NONE, AND THAT PROBLEM WAS THE BATTERY. THIS MAY OR MAY NOT HAVE BEEN RELATED, BUT I WONDER IF THE DEALERSHIP EVER CONSIDERED THE INVERTER ISSUE IN ITS ANALYSIS. THIS 2006 HH HAD ONLY 25,259 MILES AT TIME OF FAILURE, ONLY 1 OWNER, AND RCVD REGULAR MAINTENANCE FROM DEALER. *TR

DRIVING IN 6 LANES OF HEAVY TRAFFIC WE HEARD A 'THUNK' AND LOST ALL POWER. I WRESTLED THE VEHICLE TO GET IT TO COAST OFF OF THE ROAD. CAR WAS TOWED TO TOYOTA DEALER WHERE IT WAS FOUND THAT THE INVERTER NEEDED TO BE REPLACED. COST WAS $7600, AFTER A SUBSTANTIAL DISCOUNT FROM THE DEALER, WHO WAS OBVIOUSLY EMBARRASSED ABOUT CHARGING SO MUCH FOR A SINGLE PART. THE INCIDENT COULD HAVE CAUSED AN ACCIDENT, SINCE ALL POWER AND ELECTRICALLY ASSISTED DRIVING FUNCTIONS FAILED SIMULTANEOUSLY. FORTUNATELY IT DIDN'T. SUBSEQUENTLY I FOUND THAT TOYOTA HAD UPGRADED THEIR INVERTERS BEGINNING IN 2007. WE HAVE ALSO RECEIVED IN 2011 FROM TOYOTA AN "INTERIM SAFETY RECALL NOTICE" FOR THE INVERTER, BUT HAVE HEARD NOTHING SINCE. *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.
