2006 LEXUS RX400H TOTALLY SHUTTING DOWN WHILE I WAS DRIVING ON I4 TODAY. NO POWER STEERING, NO POWER BRAKES, ENGINE DIED AND LUCKILY I WAS ABLE TO COAST TO A SAFE PLACE FROM 70MPH! RIGHT BEFORE IT HAPPENED, THE CHECK ENGINE LIGHT CAME ON, THE ENGINE MISFIRED, THEN ALL OF THE LIGHTS ON THE DASHBOARD CAME ON INCLUDING THE CHECK VCS, CHECK HYBRID AND CHECK ANTI-LOCK. HAD TO HAVE IT TOWED TO OUR MECHANIC BECAUSE IT WOULDN'T START AND COULD NOT BE DRIVEN ONTO THE TOW TRUCK. CODES THAT IT THREW SAID IT WAS A HIGH VOLTAGE SYSTEM REGENERATIVE MALFUNCTION AND A BAD ENGINE COIL. IT WAS A VERY DANGEROUS SITUATION WITH IT SHUTTING DOWN ON THE INTERSTATE AND I HAD NO CONTROL WHAT SO EVER! THIS WAS THE SECOND TIME THIS HAPPENED TO ME IN THIS CAR AND THE COMPUTER WAS REPLACED THE WEEK AFTER I PURCHASED THIS CAR USED IN OCTOBER 2017.

AS I WAS DRIVING, WHEN I PRESSED THE BRAKES I COULD HEAR A GRINDING NOISE AND DID NOT FEEL ENOUGH PRESSURE ON THE BRAKE PEDAL, I GOT SCARED AND SLOWED DOWN MY SPEED. IT TURNED OUT THAT ACCORDING TO THE AGENCY SERVICE SHOP, THE BRAKE ACTUATOR NEEDS TO BE REPLACED SINCE IT DOES NOT PROVIDE ENOUGH AIR/PRESSURE WHEN I BRAKE AT A LOW SPEEDS (IT'S WORN OUT), PLUS THE CV AXLE ON DRIVER'S SIDE IS LEAKING. MY POINT IS, IT COSTS ME OVER $3,000 DLLS TO REPAIR WITH ONLY 1 YEAR LABOR/PARTS WARRANTY; I READ THAT BRAKE ACTUATORS FOR 2006, 2007. & 2008 RX400H LEXUS AND TOYOTA HIGHLANDER MODELS CAME OUT DEFECTIVE, THAT ONCE THEY GET REPLACED, THEY WILL FAIL AGAIN MOST LIKELY WITHIN A YEAR AND LEXUS HAS NOT DONE ANYTHING ABOUT IT, PRETENDING THAT THERE IS NOTHING WRONG WITH IT, ALLOWING US TO DRIVE OUR VEHICLES LIKE THAT WHILE HAVING OUR LIVES AT RISK. I AL SO READ THAT MECHANICS WORKING FOR LEXUS COMPANIES HAVE STATED THAT LEXUS SPENDS MILLIONS OF DOLLARS ON BRAKE ACTUATORS ALONE BECAUSE THEY GET REPLACED TOO OFTEN. PLEASE INVESTIGATE THIS ISSUE AND IF POSSIBLE FORCE TOYOTA/LEXUS TO DO A MASSIVE RECALL. I DO NOT HAVE THE MONEY NOR CAN'T AFFORD TO PAY THIS MUCH MONEY TO REPAIR IT. I AM STILL MAKING PAYMENTS TOWARDS THE COST OF THE VEHICLE, OVER $15,000 ABOUT 3 YEARS AGO AND I DO NOT THINK THIS IS FAIR. I AM THE ONLY DRIVER, LIVE IN A SMALL CITY, AND DO NOT DRIVE IT MUCH.

THIS WAS OUR FIRST HYBRID VEHICLE. WE WERE NOT FAMILIAR WITH THE WEIRD NOISES AND THE PARTICULARSBIN THE WAY THE VEHICLE OPERATES. THIS PARTICULAR ISSUE WAS WITH THE ABS BREAKING SYSTEM. I HAD TAKEN MY CAR TO LEXUS A FEW TIMES FOR OIL CHANGES, A PROBLEM WITH THE POWER CONVERTER AND ANOTHER ISSUE OVER THE LAST 6 PLUS YEARS I ALWAYS COMPLAINED ABOUT THE PULSING OF THE BRAKES AND THE BARKING AND OTHER NOISES COMING FROM THE CAR. THIS LAST MONTH OR SO A WARNING LIGHT FOR ABS AND ANOTHER WARNING HAD COME UP. I HAD RECENTLY HAD THE REAR BRAKES DONE AND CALLED THE LOCAL BRAKE SHOP . THEY RAN DIAGNOSTICS AND SAID THE ABS ACTUATOR NEEDED REPLACED. ERROR CODE C1256 AND C1391. I DECIDED TO LOOK UP THESE CODES AND MY LEXUS MODEL AND FOUND MANY. MANY MANY PEOPLE WITH THIS SAME ISSUE OVER THE LAST 3 YEARS OR SO. MOST RECEIVED A LETTER FROM LEXUS ADVISING OF A"WARRANTY ENHANCEMENT. I HAVE NEVER RECEIVED THIS OR ANY RECALL LETTER FOR MY LEXUS. THE PEOPLE ON THESE LEXUSCLUB BOARDS ALL HAD THIS ISSUE. MANY OF THEM DID NOT HAVE THE "WARNING LIGHT" COME ON AND WERE DENIED A REPAIR. I HAVE ALWAYS HAD THE ISSUE AND THE WARNING LIGHT CAME ON A MONTH OR SO AGO AND I FIND THAT THIS IS A HUGH SAFETY ISSUE SINCE IT'S WITH THE BREAKING SYSTEM. LEXUS IS AWARE OF IT AND EXTENDED THE WARRANTY TO 12/31/2017. WELL EVEN THOUGH I PURCHASED AN EXTENDED WARRANTY THEY SAY IT'S NOT COVERED AND ITHE REPAIR IS ABOUT $2500-$3000 . TODAY WE CALLED LEXUS CUSTOMER SERVICE AND THEY STATE IT'S OUR FAULT FOR NOT BRINGING IT IN ON TIME THEY SAID THEY DID THEIR DUE DILIGENCE AND SENT THEM. WELL I HAVE NEVER ONCE RECEIVED ANY RECALL IT WARRANTY ENHANCEMENT NOTICE. I HAVE LIVED HERE 23 YEARS AND OWNED THE CAR FOR MORE THAN 6 YEARS. LEXUS CALLS THIS A WARRANTY ENHANCEMENT"DEALERS CALL THIS A SAFETY ISSUE. SHOULD HAVE BEEN A RECALL .BUT TO AVOID THE RECALL STIGMA THEY ISSUE AN ENHANCEMENT

WHILE DRIVING 50 MPH ON A BUSY ROAD IN MA THE CAR ABRUPTLY STALLED AND LOST POWER AND ABILITY TO CONTROL IT OTHER THAN WITH A GLIDE AND MANUAL STEERING TO PULL OFF THE ROADWAY AND OUT OF BUSY TRAFFIC, WHICH COULD HAVE BEEN DEADLY FOR BOTH OUR SON AND THE PEOPLE DRIVING AROUND HIM. UPON HAVING IT TOWED TO THE LEXUS DEALERSHIP, THEY INFORMED US THAT THE DASHBOARD SENSORS WERE INDICATING A FAULTY OIL PUMP AND POSSIBLY A FAILED INVERTER. "THEY HAD NO WAY OF DETERMINING IF THE INVERTER WAS FAULTY WITHOUT FIRST REPAIRING THE OIL PUMP FOR $1200." UPON REPAIRING THE OIL PUMP, WE LEARNED THE INVERTER ($8000 REPAIR) WAS DAMAGED AND NEEDED REPAIR. THE DEALER COULD NOT EXPLAIN THIS AND HAD "NEVER SEEN OR HEARD OF SUCH A THING." FURTHER INVESTIGATION ON OUR PART, SHOWED THAT OVER 235,000 2006 AND BEYOND TOYOTA HYBRID VEHICLES HAD BEEN RECALLED FOR A FAULTY INVERTER IN 2013. WHILE OUR VEHICLE VIN DOES NOT SHOW UP ON THE RECALL LIST, WE BELIEVE WE ARE EXPERIENCING THE EXACT SAME PROBLEM. LEXUS CORPORATE IS DENYING ANY PART IN THIS AND REFUSED TO STAND BEHIND THE VEHICLE WITH ONLY 109,000 MILES AND QUICKLY CLOSED THE CASE. OUR CONCERN IS THERE ARE MORE VEHICLES OUT THERE WITH THIS ISSUE, AND THAT IT COULD BE DEADLY FOR OPERATORS AND DRIVERS. IF THE INVERTER WAS IDENTIFIED AS FAULTY ALREADY ON OVER 235,000 VEHICLES, AN EXPANDED SEARCH ON ADDITIONAL VINS NEEDS TO TAKE PLACE. LEXUS WAS VERY COMFORTABLE IN CONFIRMING THAT THEY DID NOT AND WOULD NOT STAND BEHIND THEIR VEHICLES BEYOND 100,000 MILES, AND ESSENTIALLY, IT WAS GOOD THAT OUR SON DID NOT GET INJURED, AND SORRY OUR CAR WAS ESSENTIALLY TOTALLED (VALUE OF VEHICLE IS APPROX $9000 BASED ON KELLY BLUE BOOK) FOR THE FAULTY INVERTER WHICH WAS NOT IDENTIFIED ON THE RECALL.

MAY 1, 2018 LEXUS HEADQUARTERS US 19001 S WESTERN AVE TORRANCE, CA 90501 ATTN: CUSTOMER SERVICE I AM THE OWNER OF A 2006 RX400H I HAVE RECENTLY DISCOVERED HAS AN ABNORMAL LEAK IN THE BRAKE ACTUATOR DESIGNATED C1391 ON COMPUTER DIAGNOSTIC EQUIPMENT. I HAVE BEEN ADVISED BY THE SERVICE DEPARTMENT OF A LOCAL DEALERSHIP THAT THIS HAS RENDERED THE ABS BRAKE SYSTEM INOPERABLE. FURTHER, I AM DISAPPOINTED TO LEARN LEXUS IS UNWILLING TO REPAIR THE CAR UNDER A WARRANTY EXTENSION PROGRAM ESTABLISHED BY THE COMPANY. MY VEHICLE IS BEYOND THE 10 YEAR WINDOW ESTABLISHED BY LEXUS FOR THIS PROGRAM, YET UNDER THE 150,000 MILEAGE LIMIT. THROUGH ON-LINE RESEARCH I LEARNED LEXUS HAS BEEN AWARE OF VEHICLES WITH DEFECTIVE BRAKE ACTUATORS FOR OVER A DECADE. YET, THE COMPANY FAILED TO PROVIDE NOTIFICATION THAT WOULD HAVE ALLOWED ME TO TAKE CORRECTIVE ACTION WITHIN THE WARRANTY EXTENSION TIME PERIOD. I AM DISHEARTENED TO LEARN LEXUS WOULD ALLOW AN OWNER TO DRIVE A VEHICLE WITH A LATENT SAFETY DEFECT. AND, I DO NOT UNDERSTAND WHY LEXUS WOULD JEOPARDIZE THE QUALITY BRAND IT HAS WORKED SO DILIGENTLY TO ESTABLISH. UNDER SIMILAR CIRCUMSTANCES, HONDA HONORED AN EXTENDED VEHICLE WARRANTY ON MY CAR, TOTALLY UNRELATED TO SAFETY. THE COMPANY REPLACED A FAULTY AIR CONDITIONING COMPRESSOR, WARRANTED FOR 80,000 MILES, ON A CAR WITH 85,000 MILES WITHOUT CHARGE. HONDA SUPPORTS CUSTOMERS WITH ACTION, NOT JUST WORDS. IN MY OPINION, THEY DELIVERED ON A COMMITMENT TO CUSTOMER SATISFACTION. I WOULD HAVE EXPECTED NO LESS FROM LEXUS. I URGE LEXUS TO RECONSIDER THE COMPANY'S DECISION TO NOT REPAIR A DEFECTIVE COMPONENT ON MY VEHICLE THAT COMPROMISES MY SAFETY AND THE SAFETY OF OTHERS. THANK YOU FOR YOUR CONSIDERATION IN THIS MATTER.

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.

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.

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.
