Abs actuator failure causing wheels to lock up in wet conditions along with loss of control..I nearly crashed into pedestrians when it failed. suddenly check abs light came on along with abs system malfunction...I could've been killed or killed someone. lexus will not cover the repair though they did for customers under 50k miles and under warranty which is completely criminal. Any lexus of Toyota highlander with abs assembly part # 44510-48080 needs to be recalled and replaced at Toyota and lexus immediately. They want $4000 to fix the system knowing they sold a critical safety part that malfunctions.

In about 2016, ABS light went on and I took it for repair at an independent auto shop for $400. A few months later,received a notice from Lexus of ABS issues so after speaking to Lexus, USA and sending a copy of receipt,I received a credit for having already paid to fix it. Fast forward to feb 2023 and ABS, brake,etc..lights all go on. Received estimate from Southbay lexus for over $5200 to fix Abs actuator assembly and hoses and pump kit, etc.. Found out today online after turning it in for repair at Lexus Southbay that there was primary coverage and secondary coverage offered for this exact issue and a safety/recall letter was supposed to be sent out starting in 9/2020 to owners of Lexus 2010-2012 RX450H vehicles. I never received that letter, so I missed that deadline to receive an inspection/service. Was I and my family in danger? After basic coverage expired at 48k miles, Primary coverage expired in 12/31/21 and secondary expired for owners of 10 yrs or 150k miles or less whichever comes first for this exact issue. I don’t drive much, especially since Covid started so my 2010 Lexus as of today only has only 73,124 miles. Less than 1/2 of 150k miles for secondary miles. I was never informed that there would further issues with ABS SYSTEM nor this extra primary and secondary coverage was available.

AS I WAS PULLING IN A BUSINESS CENTER TO PARK, I STEP ON THE BRAKE BUT THE CAR WOULD NOT STOP. THE ACCELERATOR CONTINUES AND CAUSED MY CAR TO RUN INTO A POWER BOX AT A BUSINESS. THIS CAUSED THE BUSINESS TO HAVE A POWER OUTAGE FOR THE ENTIRE DAY. THE WEATHER WAS CLEAR. IT WAS 11:30AM. THERE WAS NO CAR AROUND THE PARKING LOT MANY SPACES WERE EMPTIED. IM VERY FORTUNATE THAT THE CAR RAN INTO THE POWER BOX OTHERWISE THE CAR WOULD HAVE DRIVEN ITSELF INTO THE STREET! I'M A GREAT DRIVER FOR MORE THAN 20+ YEARS AND NO TICKETS OR ACCIDENTS. INSURANCE CARRIER HAD DECLARED AS TOTAL LOSS DUE FOR THE IMPACT. AIRBAGS DID NOT DEPLOYED.

ON SEPTEMBER 30, 2018, ABOUT 7:00PM, DRIVING SLOWLY IN A NEIGHBORHOOD, SLOWED EVEN MORE TO GO OVER A SPEED BUMP, A LIGHT CAME ON. SECONDS LATER, WHEN I WENT TO BRAKE TO SLOW FOR A TURN, THERE WERE NO BRAKES. I HAD TO PUSH TO THE FLOOR AND THE CAR BARELY SLOWED. MY WIFE WAS IN THE CAR. DIAGNOSED AS BRAKE ACTUATOR AND MOTOR ASSIST FAILURE. INTERNET SEARCH REVEALED LEXUS/TOYOTA HAS KNOWN THIS SERIOUS PROBLEM FOR MANY YEARS OF CARS. A SECONDARY WARRANTY ENHANCEMENT HAD BEEN ISSUED TO DEALERS. LEXUS WON'T HONOR IT BASED ON 'CUSTOMER LOYALTY' (OUR FIRST LEXUS). THEY DIDN'T EFFECTIVELY WARN AND WON'T FIX IT. BRAKES ARE AS SERIOUS AS IT GETS. THERE ARE THOUSANDS OF CARS OUT THERE LIKE TICKING BOMBS THAT COULD HAVE BRAKE FAILURE AT HIGH SPEED OR WHEN A CHILD IS CROSSING THE STREET. IT'S REPREHENSIBLE THAT THEY WON'T FIX IT. UNFORGIVABLE THAT THEY WON'T ISSUE A RECALL. WHY? BECAUSE THE PARTS ALONE ARE $4,500 AND OUR LIVES ARE WORTH LESS THAN THAT. PLEASE DO SOMETHING. REPORTING AND ASKING BECAUSE NOT IF, BUT WHEN, LIVES ARE LOST DUE TO 'COST OF DOING BUSINESS' I'VE DONE MY PART TO MAKE A RECORD FOR THE CLASS ACTION LAWSUIT. SHAME ON LEXUS/TOYOTA.

TRAFFIC ON I 5 N CAME TO A SUDDEN STOP. I STEPPED HARD ON THE BRAKES. THE ABS FUNCTION DID NOT WORK AND MY CAR SKIDDED AND WOULD HAVE GONE INTO THE LANE ON MY RIGHT IF I HAD NOT CORRECTED THE SKID. THIS COULD HAVE RESULTED IN A SERIOUS ACCIDENT WITH POTENTIAL BODILY INJURIES. I HAD THE VEHICLE INSPECTED BY LEXUS DEALER AND THEY SAID NOTHING WAS WRONG WITH THE ABS BRAKE SYSTEM AND THAT THIS COULD BE ONE IN A THOUSAND INCIDENT. I HAVE DRIVEN SEVERAL OTHER MANUFACTURERS AUTOS WITH ABS AND KNOW THAT THE LEXUS EXPERIENCE IS NOT HOW NORMAL ABS BRAKES SHOULD FUNCTION. THIS IS A SERIOUS DRIVING HAZARD AND I HAVE NOT RECEIVED A SATISFACTORY SOLUTION TO THIS ISSUE FROM LEXUS TO DATE. UPDATED 04/08/14

SERVICE BRAKES, MARCH 13, 2011 - MANSFIELD MA I PURCHASED MY 2010 LEXUS RX 450H IN DECEMBER 2010. 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. 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. HAS ANYONE ELSE NOTICED THIS ISSUE? VIEW DETAILS

I WAS DRIVING MY NEW LEXUS 450H (2,000 MILES) IN A FRESH LIGHT SNOW (1.5 TO 2 INCHES) IN INCLINE VILLAGE NV AT 25 MILES PER HOUR ON A SLIGHT DECLINE WHEN I DEPRESSED THE BRAKE PEDAL TO SLOW DOWN FOR A CURVE A FEW HUNDRED FEET AWAY. IT LOCKED THE WHEELS IMMEDIATELY AND AS A RESULT I HAD NO STEERING CONTROL. GIVEN THAT I HAD ENOUGH TIME TO GET MY FOOT OFF THE BRAKE BEFORE HAVING TO MAKE TURN AHEAD, I REMOVED MY FOOT FROM THE BRAKE (I HAVE BEEN DRIVING IN SNOW MY WHOLE LIFE SINCE I WAS RAISED IN CANADA) AND IT HAD NO EFFECT -- THE WHEELS REMAINED LOCKED AS I GAINED NO CONTROL OF STEERING AND THE VEHICLE CONTINUED TO SLIDE UNTIL IT HIT THE GUARD RAIL ACROSS THE STREET AS I ENTERED THE TURN AT SOME 10 TO 15 MILES AN HOUR. I AM CONVINCED THAT THE PROBLEM LIES IN THE 450H TRYING TO GENERATE POWER WHENEVER THE GAS PEDAL IS NOT DEPRESSED -- THIS IS DIFFERENT THAN MY FORMER LEXUS 400H WHICH ONLY TRIED TO GENERATE POWER WHEN THE BRAKE PEDAL IS DEPRESSED (I KNOW ABOUT THE NEW LOGIC BECAUSE THE POWER GAUGE (THAT SHOWS WHETHER THE BATTERIES ARE CHARGING OR DISCHARGING) SHOWS CHARGING WHENEVER ONE'S FOOT IS TAKEN OFF THE GAS PEDAL ON THE 450H, NOT ON THE 400H). NEEDLESS TO SAY, I IMMEDIATELY WENT TO THE LOCAL LEXUS DEALER AND TRADED THE VEHICLE FOR AN RX350 THAT WILL DRIVE LIKE A NORMAL CAR. I AM ONLY INTERESTED IN HAVING PEOPLE THAT LIVE IN HILLY SNOW CONDITIONS AVOID BUYING THE RX450H AS THEY WILL NECESSARILY HAVE THE SAME EXPERIENCE. I DO NOT HAVE VIN AT THIS TIME AS I AM AT MY SECOND HOME IN CALIFORNIA AT THIS TIME. *TR

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

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
