MY VEHICLE IS DISPLAYING A HYBRID SYSTEM CHECK MESSAGE, AND THE HYBRID SYSTEM MALFUNCTIONS. THIS IS CAUSING THE VEHICLE TO STALL IN DRIVE WHILE THE VEHICLE IS IN MOTION. THE VEHICLE LOSES ALL CAPABILITIES TO PROPERLY FUNCTION. I WAS ON A CITY STREET WHEN THIS HAPPENED, AND HAD TO COAST THE VEHICLE DOWNHILL IN TRAFFIC TO PULL OVER. MY ENGINE CHECK LIGHT ALSO ILLUMINATED. THIS VEHICLE HAS NOT BEEN DRIVEN REGULARLY, AS I JUST PURCHASED IT FROM A DEALERSHIP THAT HAD BEEN SITTING ON IT FOR SOME TIME. THE CARFAX CHECK OUT FOR THE VEHICLE, SO IT COULD BE A FAULTY ELECTRICAL SYSTEM INVERTER.

MY 2006 LEXUS RX400H THAT I JUST PURCHASED A FEW MONTHS AGO FROM A LOCAL DEALER (ONE OWNER PRIOR) HAS SHUT DOWN GOING DOWN OUR MOUNTAIN. TAKING MY BOYS TO SCHOOL IT JUST STOPPED IN THE MIDDLE OF THE ROAD AS WE COASTED DOWN OUR MOUNTAIN, AND THE BRAKES JUST STOPPED WORKING. I WAS ABLE TO COAST INTO MY NEIGHBORS' DRIVEWAY AND BARELY ABLE TO USE MY BRAKES. THEY DIDN'T WORK WHEN THE HYBRID LIGHT CAME ON. EXTREMELY SCARY! IT HAPPENED A FEW TIMES PRIOR TO THIS IN THESE LAST FEW MONTHS, BUT I WAS ABLE TO GET IT STARTED AGAIN PREVIOUSLY. IT'S NOW A BRICK WITH A DASHBOARD OF LIGHTS! I AM BEING TOLD BY LEXUS THIS HAS NOTHING TO DO WITH THE INVERTER RECALL AND IN FACT, THEY CLAIMED THAT THEY ALREADY REPLACED IT PRIOR TO MY OWNERSHIP A FEW MONTHS BACK, REPLACED IN 2012, LATER TO FIND OUT THAT WAS NOT TRUE. I HAVE THE SERVICE RECORDS FROM THE FIRST OWNER. I NEED TO KNOW WHAT IS WRONG WITH MY CAR. IT HAD TO BE TOWED FROM MY NEIGHBOR'S HOME ABOUT 500 FEET DOWN OUR MOUNTAIN, BACK UP TO OUR HOME ABOUT 500' BACK UP. THIS IS A SAFETY ISSUE THAT WAS EITHER NOT RECALLED OR NEEDS TO BE FIXED AGAIN AFTER THE RECALL. PLEASE GIVE ME SOME ADVICE. I WILL HAVE TO HAVE IT TOWED TO THE MECHANICS WHEN THEY OPEN. SOME PHOTOS OF MY DASH, ANY SUGGESTIONS? LEXUS NEEDS TO PAY FOR THESE REPAIRS. THIS IS A SEVERE SAFETY ISSUE! THANK GOD I WAS ABLE TO COAST INTO MY NEIGHBOR'S DRIVEWAY. I CAN'T IMAGINE HAD THIS HAPPENED ON THE HIGHWAY IN TRAFFIC. I CAN'T BELIEVE THAT LEXUS WILL NOT STAND BEHIND THIS SAFETY ISSUE AND I AM DEEPLY CONCERNED FOR THE SAFETY OF MY FAMILY. PLEASE REOPEN THIS CASE AND INCLUDE MY VIN NUMBER IN THIS RECALL.

VEHICLE APPEARED TO ENTER "FAIL-SAFE" MODE WITH REDUCED POWER WHILE DRIVING ON HIGHWAY RESULTING IN REDUCED ABILITY TO CONTROL VEHICLE. SEVERAL MINUTES LATER, WHILE DRIVING ON CITY STREET, THE VEHICLE EVENTUALLY LOST ALL POWER WHILE STOPPED AT RED LIGHT AND COULD NOT BE DRIVEN, AND POWER-STEERING ALSO FAILED. WARNING LIGHTS INCLUDED "CHECK HYBRID SYSTEM," "CHECK ENGINE WARNING LIGHT," "SLIP INDICATOR," AND PERHAPS OTHERS. AFTER TURNING OFF AND TURNING BACK ON AT RED LIGHT, THERE SUFFICIENT POWER TO DRIVE VEHICLE AGAIN, THOUGH "CHECK HYBRID SYSTEM" AND "CHECK ENGINE WARNING LIGHT" REMAINED ILLUMINATED. A COUPLE HOURS LATER, AFTER RESTARTING VEHICLE, WARNING LIGHTS WERE NO LONGER ON AND VEHICLE COULD BE DRIVEN NORMALLY. THE CONDITION APPEARS SIMILAR TO ISSUE IN TOYOTA SAFETY RECALL 13V-396. HOWEVER, OUR VEHICLE'S VIN IS NOT IN THE RANGE OF THAT RECALL. WE HAVE NOT YET CONTACTED LEXUS DEALERSHIP REGARDING THIS ISSUE. *TR

I PURCHASED THIS CAR ON 6/11/2016 WITH 125, 812 MILES. I AM NOW AT 140, 949 AND TODAY WHILE DRIVING DOWN THE ROAD WITH MY DAUGHTER IN THE CAR MY VSC MAINT LIGHT, ABS LIGHT, BRAKE LIGHT, AND TRACK STABILIZER LIGHT ALL CAME ON AT THE SAME TIME. I HAVE CONTACTED THE LEXUS DEALER IN REGARDS TO CAMPAIGN NUMBER 13V396000 AS THIS RECALL IDENTIFICATION IS IDENTICAL TO WHAT HAPPENED TODAY. THIS BEING MY ONLY VEHICLE WHICH CARRIES MYSELF AND MY CHILD THIS SEEMS TO BE A VERY DANGEROUS ISSUE. THE DEALERSHIP INFORMED ME THAT ALL OF THESE RECALLS HAVE BEEN REPAIRED AND MY VEHICLE IS NOT COVERED. IF THIS CAR WAS REPAIRED IT IS OBVIOUS IT WAS NOT REPAIRED CORRECTLY, IF AT ALL. THIS REPAIR WOULD COST ME CLOSE TO WHAT I PAID FOR THE CAR ITSELF! I WOULD LIKE DOCUMENTATION THAT MY VEHICLE HAS IN FACT BEEN REPAIRED AS I AM BETTER OFF BUYING A DIFFERENT CAR AND JUNKING THIS ONE THAN PAYING TO REPAIR IT.

I WAS TRAVELING 60 MPH ON THE HIGHWAY AND MY DISPLAY STARTED READING "CHECK HYBRID SYSTEM" AND "CHECK VSC SYSTEM" SIMULTANEOUSLY. I SEARCHED AND SAW THERE WAS A RECALL FOR THIS EXACT ISSUE (INTELLIGENT POWER MODULE INSIDE THE INVERTER MODULE) FOR CERTAIN VEHICLES OF MY EXACT MAKE/MODEL/YEAR BUT FOR SOME REASON MY VEHICLE IS NOT ON THE RECALL LIST. I TOOK IT TO THE DEALERSHIP AND THEY SAID THE REGULAR 12 VOLT CAR BATTERY WAS THE ISSUE SO THEY REPLACED IT AND THE LIGHT WENT OFF AND THE CAR TESTED NORMAL FOR SEVERAL DAYS HOWEVER WHEN TRAVELING ON THE HIGHWAY ABOUT A WEEK LATER THE SAME LIGHTS CAME ON AGAIN.

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

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

Official recalls

13V396000 · Hybrid Propulsion System: Inverter

Sep 4, 2013

Toyota is recalling certain model year 2006-2010 Highlander hybrid vehicles manufactured February 16, 2005, through July 29, 2010; and model year 2006-2008 Lexus RX400h vehicles manufactured February 23, 2005, through December 2, 2008. The Intelligent Power Module (IPM) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be illuminated on the instrument panel.

Consequence & remedy

Consequence: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. It is possible that the hybrid system will shut down while the vehicle is being driven, causing the vehicle to stall unexpectedly, increasing the risk of a crash.

Remedy: Toyota will notify owners, and dealers will replace the IPM free of charge. Owners may contact Toyota at 1-800-331-4331. Vehicles that had their IPM replaced under recall 11V-342 are not affected by this campaign.

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.
