No recall was ever issued despite the fact that a failure of the braking system.

STARTED NOTICING "BURPING" NOISE WHEN I PRESSED ON BRAKES FROM ENGINE BAY, THEN LATER I NOTICED CONTINUOUS CLICKING SOUND COMING FROM FRONT PASSENGER ENGINE BAY AFTER I WOULD TURN OFF ENGINE COMPLETELY. AS LATER TIME WENT BY THE CLICKING SOUND WOULD GET LONGER AND CONSISTENT. I ALSO EXPERIENCED THAT THE VEHICLE WOULD "LUNGE" FORWARD WHEN I WOULD START THE ENGINE AND INITIALLY SHIFT THE VEHICLE INTO DRIVE POSITION AND HAVE TO PUMP THE BRAKE PEDAL TO COMPLETELY STOP. THATS WHEN UPON FURTHER RESEARCH ONLINE I FOUND A "WARRANTY ENHANCEMENT" FROM TOYOTA REGARDING BRAKE ACTUATOR BEING REPLACED. BUT TOYOTA PUT A 10-YEAR EXPIRATION ON THE WARRANTY SO MY VEHICLE DIDN'T QUALIFY BY 6 MONTHS! TOYOTA NEVER MADE AWARE OR REACHED OUT TO THEIR REGISTERED CLIENTS OF THIS DANGEROUS RECALL THAT IS $3,000.00 TO REPLACE. I WAS INFORMED THAT WHEN THE BRAKE ACTUATOR COMPLETELY GOES BAD THAT STOPPING THE CAR WILL BE ALMOST IMPOSSIBLE TO STOP FOR THE AVERAGE DRIVER AS THE BRAKE ACTUATOR APPLIES NEEDED BRAKE FLUID PRESSURE TO ALL FOUR BRAKE CALIPERS TO SLOW THE VEHICLE DOWN.

I RECENTLY PURCHASED (07/17/12) A 2008 USED RX400H, I QUICKLY NOTICED THAT WHILE BRAKING IF THE ROAD HAS ANY BUMPS OR UNEVENNESS THE VEHICLE SURGES FORWARD DURING THE BRAKING PROCESS AND THEN RESUMES BRAKING AFTER THE SURGE. THIS HAPPENS CONSISTENTLY WHEN THERE ARE ANY BUMPS IN THE PAVEMENT. THIS IS VERY FRIGHTENING AS IT COULD EASILY CAUSE AN ACCIDENT SINCE THE BRAKING IS INTERRUPTED AND THE CAR ACTUALLY ACCELERATES WHEN IT SHOULD BE SLOWING DOWN! I HAVEN'T DRIVEN IT IN THE WINTER YET BUT I AM ALREADY CONCERNED AND UPSET THAT THIS CAR THAT I PURCHASED BECAUSE OF THE HIGH SAFETY RATINGS ON THE NHTSA SITE NOW TURNS OUT TO BE POTENTIALLY VERY UNSAFE. *TR

THE ROAD WAS SNOWY AND SLIPPERY, BUT NOT ICY. WHEN THE VEHICLE ABOUT 50 FEET AHEAD OF ME STOPPED FOR THE TRAFFIC LIGHT, I APPLIED THE BRAKES, BUT TO NO EFFECT. MY VEHICLE DID NOT SLOW, AND I DIDN'T HEAR THE NOISE OF THE ANTI-LOCK BRAKE SYSTEM. I CHOSE TO GO OFF THE ROAD AND HIT A PIPE RAILING RATHER THAN THE TANKER TRUCK THAT WAS STOPPED IN FRONT OF ME. OTHER VEHICLES AT THE SAME LOCATION HAD NO PROBLEM STOPPING. COPIES OF MY CORRESPONDENCE WITH TOYOTA ARE AVAILABLE. TOYOTA ONLY ROAD TESTED THE VEHICLE ON DRY PAVEMENT.

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

WHEN APPROACHING A STOP, AT AN APPROXIMATE 25-35 MPH, ON TYPICALLY CITY STREETS WITH SOMEWHAT UNEVEN SURFACE, WHILE APPLYING THE BRAKES, THE CAR WILL LURCH FORWARD MOMENTARILY SHORTLY INTO THE STOP. IT PRODUCES THE SUDDEN ANXIETY FEELING THAT THE CAR WILL NOT STOP AND CAN BE FELT BY DRIVER AND PASSENGERS. IT DOES NOT HAPPEN AT EVERY STOP, JUST NOW AND THEN. THIS HAS OCCURRED SINCE THE CAR WAS PURCHASED. WE HAD THE CAR SERVICED SOME TIME BACK TO ADDRESS THE "B" GEAR NOT SLOWING THE CAR ON HILLS. THE "B" GEAR ISSUE WAS RESOLVED DURING THIS SERVICE. INADVERTENTLY THE BREAKING ISSUE SEEMED TO OCCUR LESS FREQUENTLY. SINCE IT HAS BEEN SOME TIME SINCE THE SERVICE, THE BREAKING ISSUES HAS SLOWLY RESURFACED AND WITH A GREATER FREQUENCY. *TR

I OWN A 2008 LEXUS 400H HYBRID PURCHASED AS NEW LAST YEAR. ALMOST IMMEDIATELY WE NOTICED A PROBLEM WITH THE BRAKES WHEN STOPPING OVER BUMPY SURFACES -- IT WAS ALMOST AS IF THE BRAKE DISENGAGED WHILE TRYING TO STOP. WE BROUGHT IT BACK TO THE DEALER, WHO ASSURED US EVERYTHING WAS WORKING PROPERLY. THEY EVEN BROUGHT IN A NATIONAL EXPERT TO EVALUATE AND WE AGAIN WERE TOLD THE CAR WAS WORKING AS IT SHOULD. THE PROBLEM HAS NOT GONE AWAY -- IF ANYTHING IT IS WORSE -- AND IT APPEARS TO BE PRECISELY THE SAME PROBLEM NOW BEING REPORTED WITH THE PRIUS BRAKING SYSTEM. TOYOTA/LEXUS BASICALLY IGNORED US WHEN WE COMPLAINED AND THE PROBLEM IS NOT FIXED. IT IS OF MAJOR CONCERN AND HAS BEEN SINCE WE BOUGHT THE CAR. IT IS A REPLACEMENT FOR A PREVIOUS 400H THAT WAS TOTALED IN AN ACCIDENT, AND THE PREVIOUS CAR DID NOT HAVE THIS PROBLEM. *TR

WHEN BRAKING, ANY SMALL BUMP, PARTICULARLY ON WET SURFACES, CAUSES BRAKING TO CUT OUT FOR A SECOND OR TWO, AND THE CAR DOES NOT DECELERATE AS FAST. ADDED PRESSURE IS REQUIRED TO ENGAGE THE REGULAR BRAKES TO RESUME THE SAME STOPPING LEVEL. THIS NON-LINEAR STOPPING CHARACTERISTIC CAUSES INCREASED STOPPING DISTANCES AND LOSS OF CONTROL IN BRAKING (AT LEAST FOR A SECOND OR TWO). THIS SEEMS TO BE CAUSED BY THE REGENERATIVE BRAKING CUTTING OUT WHEN THE ANTI-LOCK SYSTEM ENGAGES MOMENTARILY. *JB *TR
