THE VEHICLE DASH HAS DEVELOPED PREMATURE CRACKS, AND IS SHINING AND STICKY. LEXUS CLAIMS THIS IS ONLY A COSMETIC ISSUE HOWEVER THE DASH IS AN INTEGRAL PART OF THE VEHICLE AND WITH THE DASH DETERIORATING THE FOAM PADDING IS HARDING CREATING A SAFETY ISSUE IN EVENT OF CRASH. LEXUS HAS ADMITTED TO THE ISSUE HOWEVER HAS ONLY OFFER REPAIRS TO A LIMITED ARBITRUARY NUMBER OF OWNERS WHILE ARBITRUARILY EXCLUDING OTHER OWNERS. THERE SHOULD BE A MANATORY RECALL ON THIS ISSUE AS IS A SAFETY ISSUE.

WHILE SLOWLY PULLING INTO A PARKING SPACE IN A PARKING STRUCTURE, THE CAR SUDDENLY ACCELERATED AND CRASHED INTO THE CEMENT BLOCK WALL IN FRONT OF ME. SINCE THE DISTANCE FROM HALF-WAY INTO THE PARKING SPACE TO THE WALL WAS SMALL (PROBABLY THREE TO FOUR FEET), I HAD NO TIME TO SLAM ON THE BRAKES BEFORE IMPACT. THE CAR WAS TOWED TO A LEXUS DEALER. I WAS IMMEDIATELY REFERRED TO THEIR LEGAL DEPARTMENT WHO HANDLED ALL TRANSACTIONS AFTER THAT. AN INDEPENDENT EVALUATOR INSPECTED THE CAR, RETRIEVED THE CRASH DATA RETRIEVAL RECORDER AND ISSUED A REPORT. THE CDR INDICATED THAT THE ACCELERATOR AND THE BRAKES WERE NOT PUSHED UNTIL AFTER THE CRASH, AND THAT THE SPEED IN THE FEW SECONDS BEFORE THE CRASH WENT FROM 3.7 TO 60.9 MPH. LEXUS REFUSED TO ADMIT THERE WAS A PROBLEM, STATING ONLY THAT THE BRAKES, ACCELERATOR AND FLOOR MATS SEEMED TO BE IN GOOD WORKING ORDER. I REFUSED TO DRIVE THE CAR AGAIN OR HAVE ONLY THE BODY FIXED AND SOLD TO AN UNSUSPECTING THIRD PARTY. IT WAS EVENTUALLY DECLARED A TOTAL LOSS BY OUR INSURANCE COMPANY. THERE WAS NO HELP OR ADMISSION OF A PROBLEM FROM LEXUS, EXCEPT TO TRY TO CHARGE US FOR CAR STORAGE AT THE DEALERSHIP DURING THE PROCESS. *TR

HAVING ENJOYED OWNING A LEXUS RX300, I MADE A HUGE "INVESTMENT" AND PURCHASED THE 2006 RX400H. IN APRIL OF 2014, THE VEHICLE WOULD NOT START DUE TO A FAILURE OF THE HYBRID SYSTEM. I ATTEMPTED TO JUMP START THE VEHICLE AS SUGGESTED BY THE LEXUS DEALER. UPON FURTHER INVESTIGATION I DISCOVERED THE CARPET INSIDE THE CABIN AREA WAS SOAKING WET! THE CAR HAD BEEN OUTSIDE IN THE RAIN WITH THE WINDOWS, SUNROOF AND DOORS CLOSED. ALSO, I TAKE THE CAR TO AN AUTOMATIC CAR WASH ON A REGULAR BASIS. WHILE LOADING THE CAR ON TO THE JERR-DAN TOW TRUCK, A LARGE AMOUNT OF WATER POURED OUT OF THE REAR TRUNK AREA. THE TOW TRUCK OPERATOR WAS AMAZED AT THE AMOUNT OF WATER THAT WAS POURING ONTO THE DRIVEWAY. THE VEHICLE WAS TAKEN TO THE LEXUS DEALER. AFTER SEVERAL DAYS, A LEAK IN THE REAR HATCH AREA WAS FOUND TO BE THE SOURCE OF THE WATER. THERE APPARENTLY IS A METAL SEAM WHERE THE WELDS DO NOT HOLD UP OR WERE NOT WELDED PROPERLY. WATER COLLECTED IN THE HYBRID BATTERY AREA CAUSING OVER $7000 DAMAGE. OF COURSE, LUCKILY FOR LEXUS, THE VEHICLE WARRANTY HAD EXPIRED. THE ONLY RECOURSE I HAD WAS TO MAKE A CLAIM TO MY INSURANCE, WHICH ONLY COVERED THE DAMAGES BUT NOT THE CAUSE. MY OUT OF POCKET EXPENSES ARE APPROXIMATELY $3000. WATER LEAKING FROM THE OUTSIDE INTO THE CABIN OF A VEHICLE, ESPECIALLY ONE OF THIS PRICE, IS UNACCEPTABLE. AND TO HAVE WATER COLLECT INTO THE "HEART" OF THE VEHICLE AND RENDER THE VEHICLE INOPERABLE IS FRIGHTENING. I COULD HAVE BEEN ON AN ISOLATED ROAD OR A BUSY HIGHWAY AND THE VEHICLE COULD HAVE SUDDENLY QUIT. LEXUS KNEW ABOUT THIS POTENTIAL PROBLEM BUT DID NOT ADVISE THEIR CUSTOMERS TO WATCH FOR ANY SIGNS OF MOISTURE. THE REPAIR TO THE POPPED SEAM COULD HAVE BEEN DONE BY ANY BODY SHOP OR, I'M TOLD, THE USE OF A GOOD QUALITY SILICONE. THERE IS A TECHNICAL SERVICE BULLETIN FROM 3/10/2009 THAT SPECIFICALLY ADDRESSES THIS PROBLEM: TSB-L-SB0019-09 REV 1. *TR

THE CAR IS A HYBRID. IT WOULD NOT START (THE READY LIGHT WOULD NOT COME ON), THEREFORE IT WAS INOPERABLE. FORTUNATELY, THE CAR WAS PARKED AND DID NOT DIE WHILE DRIVING. IF IT WOULD HAVE DIED WHILE DRIVING, MANY DANGEROUS POSSIBILITIES COULD HAVE INCURRED. AFTER HAVING IT TOWED TO A LEXUS DEALER IN COLUMBUS, THE SOURCE OF THE PROBLEM WAS DIAGNOSED AS WATER IN THE HYBRID BATTERY AREA. AFTER LENGTHY DISCUSSION WITH LEXUS SERVICE PERSONNEL, THEY CONCLUDED THAT "WELDS" NEAR THE HATCH HINGES HAD COME APART, WHICH ALLOWED WATER TO SEEP INTO THE INTERIOR OF THE CAR TO THE HYBRID ELECTRONIC CONTROLS. LEXUS SERVICE HAD EXPERIENCE THESE PROBLEMS BEFORE, AND HAD GUESSED AT A VARIETY OF REASONS (SUCH AS EXCESSIVE OPENING AND CLOSING OF THE HATCH, WIND CATCHING THE HATCH WHILE IT WAS OPEN, AND OTHER LAME REASONS). THERE IS NO TICKER ON THE HATCH TO COUNT HOW MANY TIMES IT WAS OPENED NOR WHAT THERE ANY GUST OF WIND THAT WOULD HAVE CAUSE THE WELDS, TWO WELDS, TO BREAK ALLOWING WATER TO SEEP INTO THE CAR. MY CONCLUSION IS THAT SINCE THE PROBLEM HAS OCCURRED BEFORE, THAT THERE IS EITHER A MANUFACTURING ISSUE, AN ENGINEERING ISSUE, OR BOTH. I AM NEITHER AN EXPERT IN THESE AREAS, BUT DO HAVE SOME COMMON SENSE. LEXUS CORPORATE OR THE DEALER WOULD NOT CONFESS TO THE WRONGDOING AND THEREFORE I HAD TO SHELL OUT OVER $1600 IN REPAIRS. THEY WANTED ANOTHER $1100 TO RE-WELD THE 3 INCH GAP ON BOTH SIDES WITH PAINTING INCLUDED. DUE TO THE EXPENSE, I HAD TO OPT FOR USING SILICONE TO SEAL THE GAPS AND AM FORCED TO DRIVE THE CAR IN DRY WEATHER. *JS

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.
