ELECTRICAL SYSTEM
I READ ON THE EDMUNDS SITE FOR LEXUS 400H, MANY OWNERS ARE COMPLAINING ABOUT THE FAILURE OF THE ELECTRIC INVERTER ON THE MODEL YEAR 2006. I OWN THIS CAR AND I HAVE NOT EXPERIENCED ANY PROBLEM. I BELIEVE YOUR AGENCY SHOULD BE LOOKING INTO THIS SITUATION AS IT APPEARS THAT OWNERS ARE REPORTING THAT LEXUS IS NOT ADMITTING TO THIS SITUATION. ONE OWNER REPORTS THAT LEXUS KNEW ABOUT THE PROBLEM IN 2006 AND CHANGED TO A DIFFERENT INVERTER STARTING WITH VIN #'S GREATER THAN 60036526. MY CAR'S VI # FALLS BELOW THAT CUTOFF AND I AM VERY WORRIED. WHEN THE INVERTER FAILS, ALL POWER TO THE VEHICLE FAILS AND THE DRIVER IS IN SERIOUS TROUBLE. THANK YOU FOR YOUR CONCERN FOR MY SAFETY WHILE DRIVING. *TR UPDATED 06/02/11

SERVICE BRAKES, HYDRAULIC
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. *TR

STEERING
I DRIVE A 2008 LEXUS RX400H. I EXPERIENCED A SERIOUS ELECTRIC POWER STEERING FAILURE, WHICH CAUSED ME TO LOOSE CONTROL OF THE CAR WHILE DRIVING. ON OCT 15, 2009, I DROVE MY CAR ON THE FREEWAY WITHOUT INCIDENT. LATER THAT DAY, I PARKED MY LEXUS RX VEHICLE, AND IN DOING SO I TURNED THE STEERING WHEEL TO THE RIGHT "LOCK' POSITION. WHEN I RETURNED TO THE CAR I MADE A HARD LEFT U-TURN TO EXIT THE PARKING AREA. AS SOON AS I ACCELERATED AND TRIED TO TURN THE WHEEL BACK TOWARDS THE RIGHT TO STEER, I REALIZED MY POWER STEERING HAD FAILED COMPLETELY, AND I COULD BARELY CONTROL THE CAR. AFTER STRUGGLING WITH THE STEERING FOR SEVERAL HUNDRED YARDS, I WAS FINALLY ABLE TO PARK THE CAR AT THE SIDE OF THE ROAD. THE INCIDENT OCCURRED IN THE EVENING AND THE VEHICLE WAS TOWED TO THE CLOSEST LEXUS DEALERSHIP THE NEXT DAY. THE LEXUS DEALERSHIP REPAIR TECHNICIAN INITIALLY REPORTED THAT "STEERING WHEEL DOES NOT WORK" - "TOWED-IN" - "LIGHT IS ON" "CHECK AND ADVISE". UPON FURTHER EXAMINATION, THE LEXUS REPAIR TECH REPORTED A "CODE C1568 POWER STEERING OPEN CIRCUIT". THE LEXUS DEALER INFORMED ME THAT THIS POWER STEERING PROBLEM WAS "COVERED BY WARRANTY". THE LEXUS REPAIR TEAM INSTALLED A COMPUTER ASSY, POWER STEERING 89650-48010. SUDDENLY, LEXUS REFUSED TO COVER ANY COST TO REPAIR THIS FAILURE BECAUSE THEY CLAIMED THEY HAD DETERMINED THAT THE POWER STEERING FAILURE COULD ONLY BE CAUSED BY A COLLISION. I DID NOT HAVE A COLLISION. I WROTE TO TOYOTA OF AMERICA, AND THEY CONFIRMED THIS CONCLUSION TO BE CORRECT. *TR

LEXUS RX400H 2006 - ABS - WHEN APPLYING BRAKES TO SLOW DOWN, IF THE CAR IS ON A BUMPY ROAD, THE BRAKES SEEM TO GIVE OUT AND THE CAR LUNGES FORWARD. THIS SEEMS TO HAPPEN AS CAR SWITCHES FROM REGENERATIVE BRAKING TO REGULAR BRAKES. I HAVE REPORTED THIS ISSUE TO THE DEALER SEVERAL TIMES, AND THEY HAVE YET TO FIND ANY PROBLEM. *TR

MY UNCLE BUMPED HIS LEG ON THE DOOR EDGE OF HIS 2006 LEXUS400H, CUTTING HIS LEG WHICH REQUIRED 5 STITCHES. THE EXTERIOR PANEL IS MUCH BIGGER THAT THE INTERIOR PANEL WHICH LEAVES A HUGE POINTED SECTION THAT STICKS OUT RATHER THAN TAPERING SAFELY IN: IF YOU LOOK STRAIGHT DOWN ON IT YOU CAN SEE HOW IT STICKS OUT. *TR

FUEL SYSTEM, DIESEL
MY 2006 LEXUS RX 400H HAS EXPERIENCED A VIBRATION DURING ACCELERATION. IT SEEMS TO STALL THE ENGINE. BRING THE VEHICLE TO DEALER FOR CHECKING. THE DEALER SAID MY VEHICLE USES INCORRECT GRADE OF GASOLINE OR NOT GOOD QUALITY GASOLINE AND RECOMMEND THAT I SHALL ALWAYS USE BETTER QUALITY GASOLINE, I.E. GASOLINE FROM SHELL. THE VIBRATION IS CAUSED BY THE MISFIRE. SUBSEQUENTLY USING THE GASOLINE FROM SHELL AND THE VIBRATION SEEMS TO BE REDUCED OR GO AWAY. LATER ON, TRY TO USE A DIFFERENT BRAND OF GASOLINE (SAME GRADE, PREMIUM) AND THE VIBRATION COMES BACK. IT SEEMS THE VIBRATION HAS SOMETHING TO DO WITH THE TIMING OF IGNITION WHICH IS CONTROLLED BY THE COMPUTER. IT DOES NOT MAKE SENSE THAT THE DESIGN OF COMPUTER SOFTWARE MODELING IS BASED ON CERTAIN BRAND OF GASOLINE OR THE DESIGN MARGIN IS SO TIGHT THAT THE IGNITION TIMING DOES NOT WORK WITH THE GASOLINE THAT IS SLIGHT DEVIATED FROM THE GASOLINE THAT LEXUS USES TO MAKE THE DESIGN. IF I DRIVE THE CAR LONG DISTANCE OR OUT OF TOWN AND CAN NOT FIND THE GAS STATION THAT SELL THE GASOLINE WHICH PRODUCE NO VIBRATION, THEN, I COULD RUN INTO A SERIOUS SITUATION THAT MY VEHICLE COULD BE STALLED OR BROKEN DOWN DUE TO SEVERE VIBRATION. *TR

SERVICE BRAKES, ELECTRIC
I WANTED TO ALERT YOU THAT OTHER HYBRID MODELS THAT WERE MANUFACTURED WITH THE SAME BRAKING SYSTEM AS THE PRIUS SUFFER THE SAME ISSUE. I HAVE A 2010 LEXUS 450H RX AND ITS BRAKES DISENGAGE WHEN I AM DRIVING ON BUMPY ROADS AND OVER POT HOLES. I LIVE IN A NORTHEASTERN CITY WITH MANY BUMPS AND MY BRAKES STOP WORKING OFTEN AND AS A RESULT I HAVE TO SLAM THEM ON MUCH MORE QUICKLY. ALTHOUGH I HAVEN'T HAD A CRASH AT THIS POINT, I CAN EASILY SEE RUNNING INTO THE BACK OF A STOPPED CAR IN FRONT OF ME IF MY BRAKES DISENGAGE AT THE WRONG TIME. THIS IS A CONTINUAL ISSUE AND I DON'T HAVE A SPECIFIC DATE BUT GIVEN THE PRIUS RECALL, I AM CONFUSED WHY MY OWN BRAKES HAVE NOT HAD A SIMILAR SOFTWARE FIX AND THE ISSUE SOUND EXACTLY THE SAME. THE DATE BELOW IS NON SPECIFIC. I HAVE HAD THE CAR FROM DEC 2009 UNTIL NOW AND THE ISSUE HAS BEEN CONTINUOUS. THE BRAKES APPEAR TO WORK FINE ON SMOOTH ROADS. *TR

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.. *TR

VEHICLE SPEED CONTROL, SERVICE BRAKES, AIR
I PURCHASED MY 2010 LEXUS RX 450H IN JULY OF 2009. EVER SINCE I BOUGHT IT, I HAVE NOTICED THAT FROM TIME TO TIME, WHEN I PRESS THE BRAKE PEDAL, THE CAR SEEMS TO SURGE FORWARD(!) MOMENTARILY BEFORE IT SLOWS DOWN. THIS HAPPENS MOST FREQUENTLY WHEN DRIVING OVER BUMPY ROADS. AND IT WILL HAPPEN EVEN IF I AM ONLY COASTING AND NOT TOUCHING THE GAS PEDAL WHEN PRESSING THE BRAKE INITIALLY. IT HAPPENS TO ME AT LEAST ONCE OR TWICE A WEEK. IT IS SOMEWHAT DISTURBING. I HAVE MENTIONED THIS TO MY LEXUS DEALER, BUT THEY HAVE DISMISSED MY CONCERNS BOTH TIMES I BROUGHT IT UP. I NOTICED THIS EVEN BEFORE I HAD HEARD OF THE TOYOTA RECALL ON HYBRID PRIUS BRAKES, BUT FROM WHAT I READ, THE ISSUE SOUNDS SIMILAR TO THE PRIUS HYBRID 2010 PROBLEMS. BUT THERE IS SO FAR NO RECALL ON LEXUS 2010 HYBRID BRAKES. HAS ANYONE ELSE NOTICED THIS ISSUE? *TR

INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) *YEAR: 2008 * MAKE: LEXUS * MODEL: RX400H * COMPONENT: THE HYBRID BRAKING SYSTEMS * VIN: [XXX] * COMPONENT -- THE 2008 LEXUS RX400H HYBRID BRAKING SYSTEMS DOES NOT WORK PROPERLY. WHEN THE VEHICLE GOES OVER A SMALL ROAD DEPRESSION OR A SMALL POT HOLE ON ONE SIDE OF THE WHEEL, IT TEMPORARILY LOST CONTROL OF THE BRAKE WHILE THE DRIVER'S FOOT IS ON THE BRAKE PEDAL. IT ALSO BEHAVES THE SAME WAY WHEN THE VEHICLES SLIPS ON THE SNOWY ROAD. IT IS VERY SIMILAR TO TOYOTA PRIUS BRAKING PROBLEMS. I REPORTED TO THE TOYOTA DEALER. THE TOYOTA DEALER TOLD ME THAT IT INTENDED THAT WAY. IF THE VEHICLE IS DRIVING IN A TRAFFIC BUMPER TO BUMPER, IT IS VERY LIKELY TO HIT THE CAR IN THE FRONT REAR END WHEN THE BRAKE SYSTEMS LET GO THE BRAKE WHILE THE OPERATOR IS PRESSING ON THE BRAKE PEDAL. IT IS A SAFETY ISSUE. IT HAPPENS EVERY TIME AND IT CAN BE DUPLICATED UNDER THE ABOVE CONDITIONS. THEY SHOULD FIX THIS LIKE THEY DO WITH THE PRIUS. *TR

VEHICLE SPEED CONTROL
AS I WAS PULLING INTO MY PARKING SPACE AT WORK THE CAR SUDDENLY ACCELERATED AS I WAS BRAKING. THE CAR WOULD NOT STOP NO MATTER HOW HARD I PRESSED ON THE BRAKE PEDAL. THE ACCELERATION CAUSED ME TO SLAM INTO THE WALL OF MY OFFICE BUILDING AND BOUNCED THE CAR BACK 3-4 FEET. AT THE TIME OF THE INCIDENT I WAS IN TOTAL SHOCK AND HAD HIT MY LEG AGAINST THE PANEL DURING THE CRASH. AS THE DAY PROGRESSED I STARTED FEELING MORE AND MORE PAIN AND DISCOMFORT THROUGHOUT MY NECK, SHOULDERS AND CHEST AREA. THIS WAS THE FIRST TIME I HAVE EVER FELT A SUDDEN ACCELERATION OF THE CAR WITHOUT PRESSING ON THE GAS PEDAL. NOW THAT THIS HAS HAPPENED I HAVE REALIZED OCCASIONALLY WHEN I PRESS ON THE BRAKE PEDAL THE CAR DOESN'T SLOW DOWN IMMEDIATELY. WHETHER THIS HAS ANYTHING TO DO WITH THE INCIDENT IS BEYOND ME. THE CAR WAS LATER TOWED TO LONGO LEXUS IN EL MONTE, CA FOR I NO LONGER FEEL SAFE DRIVING IT. NOTHING HAS BEEN DONE TO CORRECT THIS FAILURE. *TR
