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.

THE SIMILAR MODEL DESIGN PUMP WAS USED IN THE 2007-2011 CAMRY. TOYOTA HAS ISSUED A WARRANTY EXTENSION ON THAT PUMP. WHY HAS THE RX400H AND THE HIGHLANDER NOT RECEIVED THIS EXTENSION!

SLOWING THE VEHICLE AT A STOP SIGN FROM ABOUT 20MPH. CONSTANTLY APPLIED BRAKE PRESSURE. AT ABOUT 15MPH THE BRAKE PRESSURE INVOLUNTARILY RELEASED AND THE CAR ACCELERATED FORWARD. MY FOOT WAS NEVER ON THE ACCELERATOR AND CONTINUED TO APPLY PRESSURE TO THE BRAKE THROUGHOUT THE ACCELERATION. APPROX. 1/4 SECOND AFTER THE ACCELERATION, THE BRAKE CAME BACK ON AND CONTINUED TO APPLY AT THE SAME CONSTANT PRESSURE. THE ENTIRE SEQUENCE OF EVENTS LASTED ABOUT 1/2 A SECOND BUT CAUSED THE VEHICLE TO LURCH FORWARD WHILE BRAKING. THIS HAPPENS ABOUT ONCE A WEEK.

I OWN A LEXUS RX400H 2006. ON SEVERAL OCCASIONS, THE VEHICLE HAS LURCHED FORWARD (I.E. ACCELERATED) BEFORE STOPPING WHEN I APPLIED THE BRAKES AT A RED LIGHT OR STOP SIGN. I WENT TO THE WILKIE LEXUS DEALERSHIP IN HAVERFORD, PA ON JANUARY 31, 2013. A TECHNICIAN PERFORMED A TEST ON THE VEHICLE AND REPORTED NORMAL BRAKING PERFORMANCE. I HAVE FOUND SIMILAR COMPLAINTS ON NHTSA. BASED ON THESE SIMILAR REPORTS, I BELIEVE MY VEHICLE IS NOT AN ISOLATED INCIDENT. THE BRAKE SYSTEM ON THIS MODEL NEEDS TO BE INVESTIGATED. I WILL ALSO FILE A FORMAL COMPLAINT WITH LEXUS. I HAVE BEEN LUCKY TO NOT HIT A PEDESTRIAN OR VEHICLE, HOWEVER, IT SEEMS AS IF IT IS ONLY A MATTER OF TIME. OTHERS WITH SIMILAR INCIDENCES HAVE NOT BEEN SO LUCKY.

I HAVE EXPERIENCED THE EXACT BRAKING PROBLEM IN MY 2006 LEXUS RX400H AS DESCRIBED IN RECENT "CAR GUYS" COLUMN. WHILE COASTING TO A STOP WITH FOOT LIGHTLY ON BRAKE PEDAL, IF I SUDDENLY STEP HARDER ON BRAKE, IT SEEMS TO DISENGAGE FOR A SECOND BEFORE THE BRAKE TAKES HOLD AGAIN. MY GUESS, SAME AS THE CAR GUYS, IS THAT THERE IS A SLIGHT DELAY IN SWITCHING FROM REGENERATIVE BRAKING TO REGULAR FRICTION BRAKING. IT IS DISCONCERTING, BUT SOMETHING I CAN LIVE WITH AS I AM A CAUTIOUS DRIVER -- LEAVE PLENTY OF FOLLOWING DISTANCE, ETC. THIS HAS HAPPENED OCCASIONALLY, AT VARIOUS TIMES, SO "INCIDENT DATE" IS FICTITIOUS JUST TO GET THROUGH THIS FORM.

MOMENTARY ACCELERATION DURING NORMAL BRAKING. PROBLEM OCCURS REGULARLY (BUT NOT EVERY TIME) DURING NORMAL BRAKING. LEXUS DEALER SERVICE WRITER REPORTS THIS AS NORMAL AND EXPECTED PERFORMANCE. IT APPEARS THAT NORMAL BRAKING STARTS WITH REGENERATIVE BRAKES AND THEN TRANSITIONS TO FRICTION BRAKES. THERE IS A MOMENT DURING THE TRANSITION THAT BRAKING POWER IS LOST AND VEHICLE UNEXPECTEDLY ACCELERATES. TO MAINTAIN EVEN DECELERATION DURING EVERY BRAKING MANEUVER THE DRIVER MUST BE PARTICULARLY AWARE OF THIS POTENTIAL PROBLEM AND BE PREPARED TO QUICKLY APPLY SIGNIFICANT ADDITIONAL PRESSURE TO THE BRAKE PEDAL DURING THE TRANSITION PHASE THEN IMMEDIATELY REMOVE THE ADDED PRESSURE TO PREVENT OVER-BRAKING..

I HAVE A 2006, LEXUS, RX 400 H. A LEXUS CERTIFIED USED VEHICLE. THE VEHICLE WAS NEW TO ME LAST SUMMER. IT ACCELERATES SLIGHTLY WHEN I INITIATE BRAKING 2 OR 3 TIMES OUT OF 20 TIMES. I THOUGHT IT WAS "NORMAL" FOR A CAR WITH REGENERATIVE BRAKING. IT STARTLES YOU WHEN IT HAPPENS BUT HARD PRESSURE ON THE BRAKE STOPS THE CAR. YOU HAVE TO PAY ATTTENTION EACH TIME YOU BRAKE. WHAT IS SCARY IS IT ACCELERATES A LOT IN ABOUT 1 OF 100 TIMES WHEN I BRAKE. AT FIRST I THOUGHT I WAS HITTING BOTH THE GAS AND THE ACCELERATOR ... BUT I AM SURE I AM NOT. THE CAR WILL ACCELERATE TWO CAR LENGTHS BEFORE YOU CAN BRAKE IT. I THOUGHT IT WAS DANGEROUS AND BROUGHT IT TO THE DEALER LAST YEAR. WE WENT FOR A TEST DRIVE AND THE PROBLEM DID NOT OCCUR. THE DEALERSHIP RECORDED THE COMPLAINT AND TOLD ME TO KEEP AN EYE ON IT. THE 2 CAR LENGTH ACCELERATION PROBLEM WAS WORSE IN THE HOT MONTHS AND IT DID NOT SEEM TO OCCUR IN THE WINTER MONTHS. THE SLIGHT ACCELERATION PROBLEM HAS NOT CHANGED IN FREQUENCY. WITH ALL THIS TOYOTA BRAKE STUFF, I WONDER WHY I HAVE NOT HEARD OF THIS PROBLEM IN LEXUS HYBRID CARS TOO?
