These are unverified consumer reports filed with NHTSA, shown as submitted.

• 12/22/2006· SUSPENSION,TIRES

  VEHICLE PULLS TO THE RIGHT. IT WAS 4-WHEEL ALIGNED FOLLOWING INITIAL DELIVERY & ALSO AT ~22K MILES BY THE DEALER. AT 22K MILES, THE DEALER TOLD ME THAT THE FRONT TIRES WERE WORN SEVERELY INBOARD AND THE REAR HAS SOME OF THE SAME INDICATIONS (THEY WERE PREVIOUSLY ROTATED FROM THE FRONT). ALL FOUR TIRES WERE REPLACED. *NM

• 12/21/2010· ENGINE AND ENGINE COOLING,POWER TRAIN

  NO FAILURE, YET. BUT VEHICLE (LEXUS RX400H - 2006) IS A HYBRID. THERE IS A SEPARATE COOLING SYSTEM FOR THE HYBRID COMPONENTS (INVERTER, AND ELECTRIC MOTORS IN TRANSAXLE). COOLANT IS LEAKING FROM THE TRANSAXLE. IF ALL COOLANT LEAKS OUT, THE INVERTER WILL FAIL. WITHOUT THE INVERTER, THERE IS NO POWER - NO ELECTRIC STEERING, NO ELECTRIC BRAKES, AND NO MOTIVE POWER TO THE WHEELS. ADDITIONALLY, THE COOLANT MAY LEAK SOMEWHERE OR ONTO SOMETHING THAT MAY SHORT OUT OR CAUSE A FIRE. THIS IS NOT A LEAK FROM A WORN OUT COOLANT HOSE, BUT DIRECTLY FROM THE TRANSAXLE. BEING A HYBRID, THE AVAILABILITY OF ELECTRIC POWER IS ABSOLUTELY ESSENTIAL. THERE HAVE BEEN REPORTS OF INVERTERS FAILING (JUST CHECK THE LEXUS. TOYOTA AND OTHER HYBRID FORUMS) ON THE HIGHWAY AT SPEED, LEADING TO A COMPLETE LOSS OF POWER. TO THE BEST OF MY KNOWLEDGE, THERE HAVE BEEN NO INJURIES OR ACCIDENTS, BUT THE POTENTIAL IS FRIGHTENING. *TR

  The power steering and hybrid system failed and vehicle completely stopped in middle of busy freeway with no prior warnings or issues before. The safety of my son and I, and others around me during the abrupt stop of the engine. I could not move out of way. The vehicle has been serviced for this exact issue during a recall campaign lasting from 2011 to 2014. Ten years later and it is still happening! There were NO warning lamps or messages or symptoms prior to this failure. It just passed vehicle inspections for the year

  I BOUGHT A LEXUS RX400H BACK IN 2013-2014 AND RECENTLY MY CAR EXPERIENCE SOME SERIOUS ISSUES. WHILE DRIVING ON THE HIGHWAY TO TAKE MY SON TO HIS FOOTBALL GAME MY ABS SYSTEM COMPLETELY WENT OUT ON ME ALMOST CAUSING ME TO CRASH. I RECENTLY WENT TO LEXUS TO FIND OUT THE PROBLEM AND WAS TOLD IT WAS MY ACTUATOR. I ASK LEXUS ABOUT A RECALL I WAS INFORMED OF BACK IN 2016-2017 FOR ACTUATOR AND THEY STATED IT NEVER WAS A RECALLED. SINCE I NEVER WAS NOTIFIED AND ONLY HEARD ABOUT IT FROM ANOTHER LEXUS MECHANIC I ASK HIM FOR DOCUMENTS AND HE TRIED TO THROW AWAY THE PAPER THAT SHOWED MY CAR WAS RECALLED FOR THE ACTUATOR, MELTING DASH BOARD AND ECONOMIC LOSS CLASS ACTION LAWSUIT. I NEED HELP FIGURING OUT WHAT I CAN DO TO GET LEXUS TO HONOR THE SAFETY RECALLS ON MY CAR.

• 11/28/2022· ENGINE

  I was running 72mph on the interstate and the whole car shut down - shifter, engine, lost steering, EVERYTHING!

• 11/27/2017· ELECTRICAL SYSTEM,ELECTRONIC STABILITY CONTROL (ESC)

  YEARS AGO, I BEGAN TO HAVE A SERIES OF BATTERY FAILURES WHILE STILL UNDER WARRANTY. EACH TIME, LEXUS JUST TOLD ME IT WAS A DEAD BATTERY, AND REPLACED IT (PRO RATA, NOT FREE TO ME). I GRADUALLY BECAME AWARE THAT THESE FAILURES WERE BEING ACCOMPANIED BY A MESSAGE TO "SHIFT TO P WHEN TURNING OFF IGNITION," WHICH I ALWAYS DO. I SUSPECTED THAT THE VEHICLE WAS SOMEHOW SENSING THAT THE VEHICLE WAS NOT LEVEL AND WAS WRONGLY ENGAGING SOME SORT OF STABILITY SYSTEM, DRAINING THE BATTERY. THE CURRENT EPISODE IS ACCOMPANIED BY A "VSC" ERROR MESSAGE, WHICH IS INDEED A STABILITY SYSTEM. OTHERS HAVE REPORTED THIS ONLINE AS HAVING KILLED THEIR VEHICLES WHILE THEY ARE IN MOTION. I AM FORTUNATE THAT THIS DID NOT HAPPEN TO ME...YET. HOWEVER, I AM NOW OUT OF WARRANTY AND AM TOLD THIS WILL COST OVER $8000 TO FIX. I THEREFORE WANT TO ADD MY VOICE TO THE GROWING NUMBER OF AFFECTED CUSTOMERS--LEXUS SHOULD BE RESPONSIBLE FOR THIS CLEAR FLAW IN THEIR MANUFACTURING!

• 11/27/2016· SERVICE BRAKES

  THE BRAKES MAKE A STRANGE CHIRP-TYPE NOISE WHEN I APPLY PRESSURE, USUALLY IT HAPPENS WHEN I AM STOPPED AND MY FOOT ON THE BRAKE. HOLDING MY FOOT STEADY ON THE BRAKE AND IT HAPPENS RANDOMLY AND OFTEN. I HAD MY BRAKES CHECKED AND THE PADS AND ROTORS ARE FINE; THEY TOLD ME IT WAS THE ACTUATOR AND WAS A KNOWN LEXUS PROBLEM. THIS HAS BEEN HAPPENING FOR SEVERAL MONTHS AND I HAVE NEVER GOTTEN A NOTICE FROM LEXUS STATING IT IS A PROBLEM.

• 11/27/2014· ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM

  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

• 11/19/2018· ELECTRICAL SYSTEM,ENGINE

  CHECK HYBRID SYSTEM LIGHTS CAME ON AND THE VEHICLE FAILED TO START. THIS IS THE SECOND OCCURRENCE. THE INVERTER WAS REPLACED FOLLOWING THE FIRST OCCURRENCE IN 2011. THE VEHICLE WAS MOVING DURING THE FIRST OCCURRENCE.

• 11/18/2011· STEERING

  I HAVE BEEN TOLD BY THE DEALER THAT THE POWER STEERING RACK HAS DEVELOPED A SEVERE LEAK AND WILL COST $1,800 TO REPAIR. I HAVE SEARCHED THE WEB AND FOUND OTHER OWNERS WITH A SIMILAR DEFECT WITH THEIR LEXUS 330'S. IT DOES NOT SEEM THAT THE STEERING RACK IS SOMETHING THAT SHOULD BE FAILING LIKE THIS EVEN THOUGH THE CAR IS 5 YEARS OLD. *TR

• 11/18/2011· ENGINE AND ENGINE COOLING

  TL* THE CONTACT OWNS A 2006 LEXUS RX400 HYBRID. THE CONTACT WAS DRIVING 5 MPH AND MAKING A LEFT TURN WHEN A CLUNKING NOISE WAS HEARD FROM UNDER THE HOOD, FOLLOWED BY THE ENGINE STALLING. THE CONTACT ADDED THAT PRIOR TO THE FAILURE, A WARNING LIGHT ILLUMINATED STATING TO CHECK ALL SYSTEMS INCLUDING 4WD AND HYBRID. THE VEHICLE WAS TAKEN TO THE DEALER AND THE MANUFACTURER WAS CONTACTED. THE VEHICLE WAS NOT REPAIRED AND THE VIN WAS UNKNOWN. THE FAILURE AND THE CURRENT MILEAGES WERE 82,000.

• 11/17/2020· ENGINE,FUEL/PROPULSION SYSTEM

  CAR DIES AFTER DRIVING FOR A BIT. WE'VE SPENT OVER $3K FIXING FUEL PUMP, BATTERIES, AND OTHERS. FROM WHAT I'M READING IT SOUNDS LIKE MY CAR SHOULD BE ON THE INVERTER RECALL LIST, BUT IT'S NOT.

• 11/15/2016· UNKNOWN OR OTHER,FUEL/PROPULSION SYSTEM

  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.

• 11/14/2013· HYBRID PROPULSION SYSTEM

  TL* THE CONTACT OWNS A 2006 LEXUS RX400H. THE CONTACT STATED THAT SHE RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 13V396000 (HYBRID PROPULSION SYSTEM) AND STATED THAT THE PARTS WERE NOT AVAILABLE. THE MANUFACTURER WAS NOTIFIED. THE CONTACT HAD NOT EXPERIENCED A FAILURE.

• 11/09/2021· ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM

  Engine dies out as per recall but already did recall and still has same problem and code coming. Out took to Lexus Dealer to check they came out to be battery cooling fans being defective. Got estimates and was crazy amount told them don't repair suv. After talking to Dealer they state the fans has nothing to do with recall and warranty is over.

• 11/03/2010· TIRES

  THE 2006 LEXUS RX400H HAS CONTINUOUSLY DEMONSTRATED EXTREMELY EXCESSIVE INSIDE FRONT TIRE WEAR. THE ORIGINAL FACTORY TIRES WERE REPORTED AS WORN OUT AT A 10K MILE DEALER INSPECTION, AND THAT IS AFTER AN INSPECTION AT 5K MILES BROUGHT NO PROBLEMS TO MY ATTENTION. AFTER APPROXIMATELY 50K MILES, ON THE THIRD SET OF TIRES, WITH REPEATED ATTEMPTS TO ALIGN THE FRONT END AND RESOLVE THE PROBLEM, THE ISSUE APPEARS TO REMAIN. THIS VEHICLE DESTROYS FRONT TIRES AT A RATE THAT WILL TAKE CONSUMERS BY EXTREME SURPRISE AND COULD RESULT IN SERIOUS TRAFFIC INCIDENTS DUE TO FRONT TIRE FAILURE. TIRES WITH A LOWER SPEED RATING DO SEEM TO IMPROVE LIFE, AS I HAVE SEEN IN THE LAST SET OF TIRES (EACH SET TRIED HAS BEEN DIFFERENT MANUFACTURER WITH HIGHER LIFE RATINGS); HOWEVER IT DOES NOT RESOLVE THE ISSUE SINCE THE LIFE OF THE TIRES IS STILL BEING DEMONSTRATED TO BE WELL LESS THAN HALF THAT EXPECTED. *TR

• 11/01/2016· AIR BAGS,UNKNOWN OR OTHER

  CRACKED DASHBOARD ISSUE (AS PER THE SO-CALLED WARRANTY ISSUE PER CSC-10057809-9406). 10-MONTHS AGO I WAS PROMISED PARTS BY LEXUS OF MONTEREY, CA, AND, I'VE SINCE CONTACTED THEM FIVE OR MORE TIMES...NO PARTS ARE FORTHCOMING. THE LEXUS REGIONAL MANAGER OFFERS NO HELP. WHAT CAN I DO?

• 10/30/2013· STEERING

  WHILE TRAVELING EAST ON RT 2 IN MASSACHUSETTES THE RIGHT FRONT TIRE HIT A BUMP IN THE ROAD AND BLEW OUT. AT THIS INSTANT THE POWER STEERING COMPLETELY FAILED MAKING IT EXTRA DIFFICULT TO GET THE VEHICLE UNDER CONTROL. I LATER TOOK THE VEHICLE BACK TO LEXUS OF MANCHESTER NEW HAMPSHIRE WHERE I PURCHASED IT AND THEY CONFIRMED THAT THE ECU HAD FAILED BY SWAPPING IT OUT WITH A KNOWN GOOD ONE FROM ANOTHER VEHICLE. I FEEL THAT THIS WOULD BE A VERY DANGEROUS FOR ANYBODY WAS NOT STRONG ENOUGH TO BE ABLE CONTROL FORCE THAT A FLAT TIRE PUTS ON THE STEERING WHEEL UNDER THESE CIRCUMSTANCES. *TR

• 10/26/2014· SEATSFire

  I STARTED TO SMELL SOMETHING BURNING, AND MY SEAT WARMER LIGHT WOULDN'T TURN OFF. THE SEAT KEPT GETTING HOTTER TO THE POINT IT WAS UNCOMFORTABLY HOT. FORTUNATELY, I WAS ONLY 5 MI AWAY FROM THE DEALERSHIP WHEN I STARTED TO SMELL THE BURNING. DURING THAT TIME, THE PLASTIC UNDER MY SEAT BUBBLED AND WAS WITHIN MINUTES OF CATCHING FIRE ACCORDING TO THE MECHANIC. THE PREVIOUS MORNING I DROVE INTO BOSTON AND WAS STUCK IN TRAFFIC FOR AND HOUR AND 45 MINUTES. HAD THIS PROBLEM OCCURRED ONE DAY EARLIER, I HAVE NO DOUBT THERE WOULD HAVE BEEN A FIRE UNDER MY SEAT. *TR

• 10/26/2010· ELECTRICAL SYSTEM

  DEAD STARTER BATTERY - 1. SINCE THE VEHICLE WAS NEW (WE ARE ORIGINAL OWNERS) THE STARTER BATTERY WOULD BE DEAD IF WE DID NOT DRIVE THE CAR FOR 4 OR MORE DAYS (OBVIOUSLY NOT BEING ABLE TO TAKE IT ANYWHERE WHERE IT WOULD SIT WITHOUT A CHARGER NEARBY LIKE TO AN AIRPORT). LEXUS HAS REPLACED THE BATTERY 3 TIMES BUT JUST 1 MONTH AGO REPLACED IT AGAIN AND NOW AFTER A 1 WEEK TRIP TO CANCUN BATTERY WAS DEAD AGAIN. LEXUS PRETENDS TO NOT UNDERSTAND THE PROBLEM BUT MANY PEOPLE COMPLAIN OF THIS SAME PROBLEM THAT IS OFTEN MUCH WORSE WHERE THE CAR SHUTS DOWN WHEN DRIVING. MANY PEOPLE THAT HAVE HAD THIS SAME SERIES OF PROBLEMS ULTIMATELY NEED TO HAVE THE INVERTER REPLACED WHICH IS A $9K PLUS PART (SO FAR IT SEEMS WHEN ITS PROVED TO LEXUS THEY DO THIS AT NO CHARGE -- BUT MINE IS NOW OUT OF WARRANTY). 2. PROBLEM ALWAYS OCCURS IF THE CAR SITS WITHOUT BEING STARTED FOR MORE THAN 4 DAYS. 3. THEY HAVE REPLACED BATTERY 3 TIMES. WE ARE AFRAID THAT OUR PROBLEM WILL ESCALATE AND MY WIFE WILL BE DRIVING WITH OUR 8 & 10 YEAR OLD CHILDREN AND THE BATTERY SYSTEM WILL FAIL CAUSING THE ENTIRE CAR TO SHUT DOWN AND SHE IS NOT STRONG ENOUGH TO STEER TO SAFETY WHEN BRAKE AND STEERING ARE NOT WORKING. IT IS UNFAIR FOR US TO POTENTIALLY HAVE TO SELL THE VEHICLE AT A HUGE LOSS TO AVOID THIS POTENTIAL ISSUE (AND THEN SOMEONE ELSE WILL HAVE THE PROBLEM). *TR

• 10/19/2012· VEHICLE SPEED CONTROL

  THIS IS A SUDDEN ACCELERATION/UNINTENDED ACCELERATION INCIDENT. I TURNED OFF OF A MAJOR ROAD INTO A SMALL, CROWDED PARKING LOT. AS I SLOWLY PULLED INTO AN AVAILABLE SPACE (WITH A CAR PARKED ON EACH SIDE OF ME), THE CAR SUDDENLY ACCELERATED. ALTHOUGH I KEPT JAMMING ON THE BRAKES AS HARD AS I COULD, THEY DID NOT STOP THE CAR--IT KEPT GOING FORWARD. THE CAR WENT OVER THE WOODEN RAILROAD TIE AT THE END OF THE PARKING SPOT AND CRASHED THROUGH A WOOD FENCE. THE ONLY REASON THE CAR FINALLY STOPPED IS DUE TO THE RAILROAD TIE, WHICH SLOWED THE CAR AT THE REAR AXLE AS THE FRONT OF THE CAR HUNG IN THE AIR. *TR

  Dear manager: I have this 2006 LEXUS RX400H which has CHECK VSC SYSTEM and CHECK HYBRID SYSTEM problems. When I was driving on the highway, the cruise control button is unable to turn on, when at speed of 65 MPH it will suddenly stall in the middle of the road and the READY light will be off and the vehicle has to be stopped by the emergency lane which is REALLY DANGEROUS. I have searched online and found out there were many complains about this issue and LEXUS issued a recall for this type of car and the dealer can change the inverter and ICM free of charge. This recall link is as follows: https://static.nhtsa.gov/odi/rcl/2011/RCONL-11V342-6633.pdf So tonight I am sending this message to see if you can help me to solve this problem.

• 10/02/2025· FUEL/PROPULSION SYSTEM

  After adding gasoline to the tank, gasoline begins dripping from the left rear of the vehicle to the rear of the left rear wheel well. This happens even if the tank is only filled to 2/3 of a tank. I have stopped filling up since when the tank is filled up a LARGE amount of gasoline leaks out onto the ground. FIRE HAZARD while parked or driving. I have seen HUNDREDS of reports of this problem reported online.

• 09/13/2008· SERVICE BRAKES, ELECTRIC

  THE REGENERATIVE BRAKES ON MY LEXUS RX 400H WILL STOP WORKING DURING NORMAL BRAKING OPERATION CAUSING THE OPERATOR TO HAVE TO APPLY MORE PRESSURE TO THE BREAK PEDAL TO COMPENSATE FOR THE LOSS OF REGENERATIVE BREAKING. THIS IS AN INTERMITTENT PROBLEM AND YOU NEVER KNOW WHEN YOU WILL HAVE TO MAKE A BRAKING ADJUSTMENT. THIS PROBLEM FIRST STARTED IN DECEMBER, 2007. I PURCHASED THE CAR IN APRIL, 2005. I DO NOT FEEL THAT AN OPERATOR OF A VEHICLE SHOULD HAVE TO MAKE SUDDEN ADJUSTMENTS IN THEIR BREAKING ACTION TO COMPENSATE FOR THE DISENGAGEMENT OF A PORTION OF THE BREAKING SYSTEM, ESPECIALLY WHEN YOU NEVER KNOW IF IT IS GOING TO HAPPEN. I HAVE TAKEN THIS BACK TO THE LEXUS DEALER ON SEVERAL OCCASIONS AND THEY TELL ME THAT THEY BELIEVE THE CAR IS WORKING NORMAL, EVEN WHEN THE PROBLEM IS INTERMITTENT. *TR

  TWO DIFFERENT TIMES, AFTER DRIVING 2 HOURS OVER A MOUNTAIN PASS ON THE HIGHWAY, PULLING A SMALL POPUP CAMPER, THE VEHICLE DIED AT THE CAMPGROUND. AFTER DOING SOME RESEARCH, I FOUND OUT THAT TOYOTA/LEXUS USED PRIUS INVERTERS ON 2006 HYLANDER AND RX440H VEHICLES AND THEY OVERHEAT AND FAIL BECAUSE THEY ARE MEANT FOR A SMALLER VEHICLE AND HAVE INADEQUATE SOLDER. THERE IS A RECALL FOR INVERTERS ON 2006, BUT MY VIN NUMBER IS NOT SHOWING UP AS QUALIFYING. THE INADEQUATE INVERTERS WERE INSTALLED ON RX400H MODELS WITH VIN NUMBERS ENDING IN 60036526 AND LOWER. MY VIN NUMBER ENDS 60029638-- SO AN INADEQUATE INVERTER WAS INSTALLED IN MY VEHICLE. TOYOTA/LEXUS NEEDS TO ADD MY VIN NUMBER TO THE RECALL GROUP, BUT THEY ARE HESITANT BECAUSE OF THE EXHORBITANT COST OF THE INVERTER. THIS IS A SERIOUS SAFETY ISSUE BECAUSE THE OVERHEATED INVERTER CAN CAUSE THE VEHICLE TO GO INTO A FAIL/SAFE- LIMP HOME MODE SUDDENLY AND THE VEHICLE CAN COMPLETELY SHUT DOWN WHILE DRIVING CAUSING THE VEHICLE TO STALL UNEXPECTEDLY, WITH HIGH RISK OF A CRASH AND POSSIBLE INJURY OR DEATH

  AS I'M SURE YOU ARE AWARE ' HYBRID CARS ARE VERY QUIET AND THUS PRESENT A DANGER TO PEOPLE WALKING THROUGH PARKING LOTS. THE DANGER IS PARTICULARLY SERIOUS WHEN THOSE DRIVING THE HYBRIDS ARE BACKING OUT OF PARKING SPACES - NO MATTER HOW CAREFULLY THE DRIVERS ARE BACKING OUT! PEDESTRIANS DEPEND ON THEIR HEARING TO ALERT THEM TO CARS BACKING OUT, SO THEY SIMPLY WALK RIGHT BEHIND A CAR THAT IS ALREADY MOVING. I OWN A 2006 LEXUS 400H AND I HAVE BEEN TRYING TO PURCHASE REPLACEMENT BACK-UP LIGHTS THAT BEEP TO ALERT PEDESTRIANS, BUT NONE ARE AVAILABLE FROM ANY SOURCE. I URGE THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION TO TAKE QUICK ACTION TO ENSURE THAT FUTURE MODELS INCLUDE EXTERNAL SOUND FOR HYBRIDS WHEN THEY ARE BACKING UP AND ALSO TO MAKE IT POSSIBLE TO PURCHASE REPLACEMENT BACK UP LIGHTS THAT PROVIDE THAT SAME CAPACITY FOR OLDER HYBRID MODELS.

I AM BEGINNING TO BE CONCERNED. ABOUT THE SAFETY AS IT APPEARS THE DASH IS DETERIORATING MORE AND MORE AS THE DAYS GO BY AND AM CONCERNED FOR ANYONE RIDING WITH ME.

I DID NOTICE THAT I HAD RUN OVER ANY ROAD DEBRIS BUT THE TIRE HAD A TWO INCH SLICE IN THE SIDEWALL. THE TIRE WAS IN GOOD CONDITION, ORIGINAL LEXUS EQUIPMENT, A MICHELIN 235/55R18 . TODAY, MY DAUGHTER WHO OWNS A 2007 TOYOTA HIGHLANDER HYBRID (BASICALLY THE SAME CAR AS MY LEXUS 400H) HAD A SIMILAR INCIDENT WITH HER BABY IN THE CAR. SHE HIT A CURB WITH THE CAR HARDLY MOVING. THE TIRE "BLEW", AND LIKE MINE, WENT FLAT IMMEDIATELY. SHE HAD A SIMILAR TWO INCH GASH IN THE SIDEWALL. THE TIRE WAS ORIGINAL TOYOTA EQUIPPED. I'VE BEEN DRIVING A LONG TIME. I'VE NEVER SEEN SIDEWALL BLOWOUTS LIKE THIS (MINOR PROVOCATION) SINCE RADIAL TIRES WERE INTRODUCED. PLEASE CHECK OUT THESE TOYOTA PROVIDED TIRES. *TR
