WHILE BACKING OUT OF MY DRIVEWAY, I BUMPED A TREE WITH THE PASSENGER'S SIDE MIRROR. THE IMPACT WAS SLIGHT, ESTIMATED SPEED WAS 5MPH AS THE DRIVEWAY WAS ICY. THE WHEELS WERE NOT TURNED MUCH AS THAT PORTION OF THE DRIVEWAY IS STRAIGHT. AFTER THE IMPACT, I FOUND THAT THE WHEEL WAS VERY DIFFICULT TO TURN AND THE "P/S FAIL" LIGHT WAS LIT ON THE INSTRUMENT CLUSTER. AFTER EXAMINING THE OUTSIDE OF THE CAR, THE ONLY VISIBLE DAMAGE TO THE CAR WAS A PAINT CHIP ON THE MIRROR. THERE WERE NO FLUID LEAKS. THERE WAS A SAFETY RECALL IN NOV. 2011 (LEXUS SAFETY CAMPAIGN 9LC) FOR THIS YEAR MAKE AND MODEL OF VEHICLE DUE TO OTHERS HAVING SIMILAR SUDDEN AND UNEXPLAINED LOSS OF POWER STEERING. MY INSURANCE COMPANY DENIED MY CLAIM FOR REPAIR BECAUSE THE EXPERTS THEY CONSULTED SAID THIS TYPE OF IMPACT COULD NOT HAVE CAUSED A LOSS OF POWER STEERING. I HAVE WRITTEN LEXUS DESCRIBING THE ISSUE AND AM AWAITING A RESPONSE. HAD THE POWER STEERING FAILURE OCCURRED AFTER HITTING ONE OF THE NUMEROUS POTHOLES ON THE HIGHWAYS, INSTEAD OF IN MY DRIVEWAY, THE CONSEQUENCES TO MY WIFE AND I COULD HAVE BEEN MUCH MORE SEVERE. *TR

ON NOVEMBER 12, 2014 EVENING, I WAS DRIVING ALONG AND GOING UP A HILL IN MY CITY STREET AND SUDDENLY I HEARD A THUMP SOUND AND THEN MY LEXUS RX400H LOST ALL POWER AND THE CAR STALLED. IT WAS DANGEROUS BECAUSE THE VEHICLE LOST POWER AS I WAS GOING UP A STEEP HILL. LUCKILY, I WAS ABLE TO STOP THE VEHICLE AND PUT THE PARKING BRAKE ON. WHEN THE VEHICLE STALLED, MY DASH LIT UP WITH "CHECK HYBRID SYSTEM" , "CHECK VSC" AND OTHER LIGHTS ALSO CAME ON. I TRIED TO START THE CAR, BUT THE HYBRID "READY" LIGHT WOULD NOT STAY ON. THE CAR WOULD NOT START. I HAD TO TOW THE VEHICLE TO A LEXUS DEALER. I PUT A NEW BATTERY IN THE VEHICLE AND THAT STILL DID NOT FIX THE PROBLEM. THEN, THE LEXUS DEALER MECHANIC DID A COMPUTER DIAGNOSIS AND SAID THAT IT INDICATED "HYBRID INVERTER PROBLEM". MY VEHICLE WAS PREVIOUSLY BROUGHT INTO LEXUS DEALERSHIP FOR AN EARLIER RECALL FOR IPM MODULE BUT THE DEALER AT THAT TIME SAID MY VEHICLE WAS NOT WITHIN THE SERIAL RANGE AFFECTED AND NOTHING WAS DONE TO THE VEHICLE AT THAT TIME. I PHONED LEXUS USA ON NOVEMBER 13, 2014, AND THEY CONFIRMED MY VEHICLE WAS UNDER THE RECALL DLF, NHTSA RECALL NUMBER 13V396. I WAS NEVER NOTIFIED BY LETTER. THE LEXUS DEALER THEN PUT IN THE IPM RECALL PART TOYOTA PART 04001-29148 PART AND THE VEHICLE STARTED PROPERLY. MY VEHICLE HAS ABOUT 94,000 MILES AND JUST OVER 8 YEARS OLD AND TECHNICALLY OUT OF WARRANTY. HOWEVER, THE LEXUS DEALER REPLACED THE PART WITH LABOR AT NO CHARGE. THIS REPAIR COSTS THOUSANDS OF DOLLARS IF NOT COVERED BY LEXUS. WHEN I BOUGHT MY LEXUS HYBRID, I DID NOT BE EXPECT THAT THE HYBRID VEHICLE COULD FAIL IN SUCH A CATASTROPHIC WAY. I'M A LITTLE FEARFUL TO DRIVE THIS VEHICLE AGAIN IF IT HAPPENS AGAIN, AND I HOPE LEXUS WILL TAKE CARE OF THIS ISSUE IT HAPPENS AGAIN. THERE IS DEFINITELY SOMETHING DEFECTIVE WITH THE HYBRID INVERTER, AND IT COULD BE DANGEROUS IF IT FAILS WHILE DRIVING. *TR

THE CHECK ENGINE LIGHT AND P0AA6 WARNING ILLUMINATED AND VEHICLE WENT COMPLETELY DEAD, COULD NOT START UP. THERE WERE CRACKED BODY SEAMS ABOVE THE REAR DOOR STRUT MOUNTS ALLOWING WATER INTRUSION TO FLOOD THE ENTIRE BOTTOM WELL UNDER THE FLOOR BOARDS WHICH SHORTED OUT THE ENTIRE HYBRID BATTERY SYSTEM. THERE WERE NO VISIBLE SIGNS OF WATER INTRUSION INSIDE THE CABIN OF THE VEHICLE, NOTHING WAS WET. APPARENTLY, LEXUS HAS TWO TSB'S ON THIS ISSUE, L-SB-0019-09 & L-SB-0045-09, ON HOW TO REPAIR THE SEAMS SINCE OVER TIME THERE APPEARS TO BE A STRUCTURAL FLAW ALLOWING THE SEAMS TO SEPARATE. THE WATER INTRUSION HAPPENS SILENTLY AND WITHOUT WARNING AND PRESENTS A SEVERE SAFETY HAZARD AS YOU GET WATER INTO AN ELECTRICAL SYSTEM AND PARTS BEGIN SHORTING OUT WITHOUT ADVANCED WARNING. IMAGINE TRAVELING AT A HIGH SPEED AND THE HYBRID BATTERY SHORTS AND THE VEHICLE ABRUPTLY STOPS! OR AN ELECTRICAL SHORT STARTS A FIRE! LEXUS IS AWARE OF THE POTENTIAL PROBLEM AND HOW COSTLY THE DAMAGE IS AND THE SAFETY RISKS ASSOCIATED AS A RESULT AND HAS CHOSEN NOT TO ISSUE A RECALL OR LIMITED CAMPAIGN TO ALLOW FOR A SIMPLE REPAIR OF THE SEAMS TO PREVENT MAJOR DAMAGE FROM OCCURRING. *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.
