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 BACKING OUT OF OUR DRIVEWAY WHEN THE CAR SUDDENLY LOST POWER TO THE WHEELS AND ALL OF THE WARNING LIGHTS CAME ON. SHE WAS UNABLE TO MOVE THE CAR FORWARD OR BACKWARD TO GET THE CAR OUT OF THE LANE OF TRAFFIC. WE GOT THE CAR TOWED TO THE LOCAL TOYOTA DEALERSHIP. THEY INFORMED US THAT THE INVERTER WAS BAD AND WE NEEDED A NEW ONE. WE HAD RECEIVED A RECALL NOTICE ABOUT REPLACING AN "INTELLIGENT POWER MODULE" AND HAD THE REPAIRS DONE JAN 9TH 2013. THE REPAIR SHOP HAS SAID THAT THE REPLACED PART IS WORKING AND THAT IT IS THE INVERTER ITSELF THAT HAS GONE BAD. I HAVE SEEN MANY OTHER COMPLAINTS ABOUT THIS PROBLEM ONLINE. I AM JUST THANKFUL THAT SHE WASN'T GOING HIGHWAY SPEED WITH OUR CHILD IN THE CAR WHEN SHE LOST POWER. THAT COULD HAVE BEEN VERY DANGEROUS. *TR

WHILE DRIVING THE VEHICLE AT APPROX. 60 MILES PER HOUR THE BRAKE LIGHT AND VCS SYSTEM LIGHT CAME ON. THE WARNING LIGHT ALSO WENT ON. IN ACCORDANCE WITH THE OWNER'S MANUAL, I TOOK THE CAR TO AN AUTHORIZED TOYOTA DEALERSHIP. ACCORDING TO THE AUTOMOBILE STATUS REPORT, THE ABS-HYDRAULIC CONTROL ASSEMBLY: WITH ECU MUST BE REPLACED. ACCORDING TO COMPLAINTS I RESEARCHED ON-LINE, SEVERAL COMPLAINTS HAVE BEEN DOCUMENTED RELATING TO THIS MAKE, MODEL AND ABS SYSTEM. I FILED AN INCIDENT WITH TOYOTA (REFERENCE NUMBER: [XXX]). THE INTAKE REPRESENTATIVE WHO CHECKED WITH THE DEALERSHIP SAID THIS WASN'T A RECALL ITEM AND NO SUPPORT WAS AVAILABLE TO EXTEND THE WARRANTY ON THE PART. SHE CONFIRMED THAT THE SERVICE DEPARTMENT STATED THAT THERE WAS NO DEFECT IN THE WORKMANSHIP. I ASKED [XXX] (THE PERSON I SPOKE TO) IF I COULD TAKE THE VEHICLE FOR A SECOND OPINION RELATING TO THE ABS PART. I ALSO ASKED FOR VERIFICATION THAT THE SERVICE DEPARTMENT ACTUALLY CHECKED THE PART FOR A DEFECT OR IS QUALIFIED TO DETERMINE IF IN FACT IT IS A MANUFACTURERS' DEFECT. THE DEALERSHIP QUOTED THAT THE ABS PART; BRAKE FLUSH/FLUID EXCHANGE/BF; ENGINE AIR FILTER REPLACEMENT;A/C SERVICE-ACS; COOLANT FLUSH (PREMIUM)-CF; AND FUEL INJECTION SERVICE WOULD COST $2,250. I ALSO ASKED THE TOYOTA CUSTOMER SERVICE REPRESENTATIVE WHAT THE BATTERY EXPECTANCY ON THE CAR IS AND WHETHER THE MANUFACTURER OFFERS ANY SUPPORT IN TERMS OF THE COSTS. I WAS TOLD BY THE DEALERSHIP THAT THE BATTERY CAN COST $5,000.00 TO REPLACE BUT THE MANUFACTURER MAY OFFER SOME SUPPORT. I WOULD APPRECIATE YOUR ASSISTANCE, RESEARCH AND FILLING OF THIS COMPLAINT. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

WE WERE DRIVING ON THE NJ TURNPIKE. SUDDENLY, THE CAR STALLED AND THE STEERING LOCKED. LUCKILY, WE JUST STARTED THE HOUR LONG DRIVE AND WERE ON THE SLOW LANE AND WAS ABLE TO GLIDE THE CAR OVER SAFELY TO THE SHOULDER. THE CHECK "CSV" AND "CHECK HYBRID SYSTEM" LIGHTS CAME ON AND THE HYBRID BATTERY SHOWED NO ENERGY. THE CAR WOULD NOT START AND WAS TOWED TO THE CLOSEST TOYOTA DEALERSHIP. THERE WERE NO PRIOR WARNINGS ABOUT BATTERY ERRORS OR PROBLEMS BEFORE COMPLETELY STALLING. IT IS UNDERSTANDABLE PROBLEMS WILL ARISE, BUT WITH NO WARNING AND A CAR STALLING ON A MAJOR HIGHWAY, THE INCIDENT COULD HAVE BEEN EXTREMELY DANGEROUS. *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.
