2010 Lexus RX Brakes Problems

ABS TCS lights came on and check brakes warning was displayed. The power assist failed making the brake pedal very hard to press in order to stop.

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.

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.

ABS System failure Suddenly while driving in wet conditions abs malfunction appears check brake system appears, brakes locked up several times under light braking pressure first occurred two months ago. Dealer inspected estimated repair 3700$ Not isolated event as I see many complaints online from other owners

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.

BRAKE BOOSTER MALFUNCTION, I WAS ENTERING THE FREEWAY, SUDDENLY MY BRAKE PEDAL STIFFENED UP AND NO BRAKES, KEEP PUMPING BRAKES AND PARKING BRAKE LIGHTS CAME ON AND BRAKE MALFUCTION CAME ON THE DASH. ONLY 103,973 MILES

WHEN I WAS ON REVERSE GEAR IN MY LEXUS TRYING TO GET OUT OF THE PARKING SPOT, THERE WAS SUDDEN UNINTENDED ACCELERATION CRASHING MY LEXUS INTO A PARKED VEHICLE. I TRIED TO HIT THE BRAKES WHICH DID NOT WORK AND THE VEHICLE DID NOT STOP. THERE WAS EXTENSIVE DAMAGE TO THE PARKED CAR.

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

HAD TO REPLACE THE BRAKE FLUID IN THE VEHICLE AT 30000 MILES. LEXUS REQUIRES THIS SUPPOSEDLY TO MAINTAIN THE INTEGRITY OF THE BRAKING SYSTEM AND PROVIDE A SAFE VEHICLE. I FEEL THIS IS A SAFETY DEFECT IN THE DESIGN. ANY VEHICLE' SHOULDBE ROBUST ENOUGH TO LAST MUCH LONGER THAN THIS WITHOUT THIS LEVEL OF SERVICE BEING REQUIRED BY THE MANUFACTURER. IF THE VEHICLE DOES REALLY NEED THIS, THAN LEXUS SHOULD COVER IT UNDER WARRANTY. BRAKES ALSO REQUIRED DISASSEMBLY AND CLEANING AT 15000 MILES AT CUSTOMERS EXPENSE. *TR

I WENT OUT TO GRAB A BITE TO EAT FOR MY DAUGHTER AND I CAME TO A STOP LIGHT AT A MAJOR INTERSECTION. I RECEIVED THE TURN ARROW SO I ACCELERATED THRU THE TURN AND THEN PUNCHED THE GAS TO MAKE IT THRU THE NEXT LIGHT THAT WILL TURN RED IF YOU DON'T GIVE IT A LITTLE GAS TO GET THRU IT. I MAKE IT THRU THE LIGHT AND GET IN THE RIGHT LANE TO SLOW DOWN TO MAKE MY TURN AND MY BRAKES DON'T WORK AND MY CAR STARTS ACCELERATING ON ITS OWN. I HAVE NO CONTROL OF THE SPEED SO I THROW THE CAR IN NEUTRAL AND KEEP SLAMMING THE BRAKES WHILE THE BRAKE MALFUNCTION LIGHT APPEARS. I'M NOT SURE HOW MY CAR SLOWS DOWN AND I MAKE A RIGHT TURN INTO A PARKING LOT AND MY ENGINE IS STILL SOUNDING LIKE IT IS ACCELERATING AND I AM IN NEUTRAL. MY CAR ROLLED TO A STOP, I SHUT IT DOWN AND CALLED THE LEXUS LINE. THE HAD A TOWING COMPANY OUT WITHIN AN HOUR AND THE TOW TRUCK DRIVER TOLD ME THIS IS AT LEAST THE 10TH TIME HE HAS HAULED THIS TYPE OF CAR FOR THE SAME THING. *TR

TL* THE CONTACT OWNS A 2010 LEXUS RX350. THE CONTACT WAS DRIVING APPROXIMATELY 25 MPH WHEN THE BRAKES WERE APPLIED BUT THE VEHICLE WOULD NOT RESPOND. THE BRAKE PEDAL WAS ABNORMALLY DEPRESSED INTO THE FLOORBOARD AND THE CONTACT CRASHED INTO A FIRE HYDRANT AND THE SIDE OF A BUILDING. ONCE THE VEHICLE CAME TO A COMPLETE STOP, THE AIR BAGS DEPLOYED. THE CONTACT WAS NOT INJURED. THE VEHICLE WAS TOWED THE DEALER BUT WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 25,000.

2010 LEXUS RX450H. CONSUMER STATES PROBLEM WITH BRAKING SYSTEM *TGW THE CONSUMER NOTICED AFTER DRIVING THE VEHICLE FOR A FEW MONTHS, THAT IT SOMETIMES SURGED FORWARD A FEW FEET WHILE BRAKING OR WHEN LETTING OFF THE BRAKE. THE DEALER INFORMED THE CONSUMER THE BRAKING SYSTEM WAS TYPICAL OF A HYBRID VEHICLE. THE CONSUMER STATED A COUPLE OF WEEKS LATER, THE VEHICLE SURGED FORWARD AGAIN AS SHE WAS BRAKING. *JB

I WAS DRIVING APPROXIMATELY 30 - 40 MPH ON THE FREEWAY. I WENT TO MAKE A LANE CHANGE, LOOKED OVER MY SHOULDER TO MAKE SURE LANE WAS CLEAR, AS I TURNED BACK, THE CAR IN FRONT OF ME STOPPED. I PUT ON MY BRAKES, THERE WAS NO RESPONSE FROM MY BRAKES, THEY DISENGAGED. MY CAR SURGED FORWARD AND HIT THE CAR IN FRONT OF ME. MY SEATBELT DID NOT HAVE ANY TENSION, THEREFORE, MY BODY HIT THE STEERING WHEEL. NOTHING HAS BEEN DONE. THE ACCIDENT JUST HAPPENED. *TR

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

TL* THE CONTACT OWNS A 2010 LEXUS RX450H. WHILE DRIVING APPROXIMATELY 25 MPH THE CONTACT DROVE OVER A BUMP IN THE ROAD WHILE DEPRESSING THE BRAKE PEDAL. THE VEHICLE STALLED AND SUDDENLY THE BRAKES DISENGAGED. THE CONTACT STATED THE FAILURE OCCURRED SEVERAL TIMES AND CAUSED A REAR END COLLISION WITH ANOTHER VEHICLE. THERE WERE NO INJURIES AND A POLICE REPORT WAS NOT FILED. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIANS WERE UNABLE TO DIAGNOSE THE FAILURE. THE TECHNICIANS STATED THE REGENERATIVE AND THE HYDRAULIC BRAKING SYSTEM BEGAN TO SWITCH FROM ONE TO THE OTHER AND CAUSED THE HESITATION. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 2,000.

TL*THE CONTACT OWNS A 2010 LEXUS RX 350. WHILE DRIVING THE VEHICLE AT APPROXIMATELY 50 MPH, THE CONTACT DEPRESSED THE BRAKE PEDAL BUT THE VEHICLE DID NOT SLOW DOWN. AS A RESULT, THE CONTACT CRASHED INTO ANOTHER VEHICLE. THERE WERE NO INJURIES BUT A POLICE REPORT WAS FILED. THE VEHICLE WAS TAKEN TO AN AUTOMOTIVE BODY SHOP BUT NO REPAIRS WERE MADE WHEN THE COMPLAINT WAS FILED. THE VIN WAS UNAVAILABLE. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 5,000.

LEXUS HYBRID SUV 2010 RX450H. CAR WAS IN SNOW SETTING AND WHEN I TRIED TO BRAKE ON A LIGHT SNOW SURFACE, THERE WAS NO RESPONSE FROM THE BRAKES AND I ALSO WAS UNABLE TO STEER. I CONTINUED FORWARD UNTIL I REACHED CLEAR PAVEMENT AND WAS THEN ABLE TO BRAKE. THIS HAPPENED 3 TIMES TODAY UNDER THE SAME CONDITIONS. LUCKILY NO CARS WERE COMING OR I WOULD HAVE BEEN HIT BROADSIDE ON A BUSY STREET. *CN

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 HAVE A NEW 2010 LEXUS RX 350 KEEP STALLING WHILE I WAS WAITING FOR TRAFFIC LIGHT, PROBLEM STATED SOON AFTER I STARTED DRIVING , WHILE MILEAGE WAS AROUND 1500, WHEN THE CAR STALLED ABS (ANTI BRAKE SYSTEM) SIGN SHOWED UP. I TOOK THE CARS SEVERAL TIMES BACK TO LEXUS, THEY USED THEIR COMPUTER TO CHECK COMPUTER RECORDS OF MY CARS AND CLAIMED NOTHING WRONG WITH THE CAR, UNTIL THE THIRD TIME I WENT BACK , THE BRAKE MALFUNCTION WARNING SIGN SHOWED UP WHILE LEXUS'S TECHNICIAN WAS INSIDE THE CAR WITH ME, THEN THEY KEPT THE CAR 10 DAYS AND REPAIRED THE PROBLEM, BUT STILL CLAIMED NOTHING ELSE IS WRONG WITH THE CAR, CANNOT EXPLAIN WHY THE CAR STALLED, THEY CLAIMED COMPUTER OF MY CAR DIDN'T RECORD ANY STALLED HISTORY THEREFORE NO PROOF CAR STALLING PROBLEM. I TOLD THEM THE COMPUTER OF MY CAR IS SO DEFECT THAT THEY DIDN'T FIND BRAKE MALFUNCTION PROBLEM UNTIL THE SIGN SHOWED UP IN DASHBOARD, WHY ARE THEY STILL RELY ON THE COMPUTER? THEY KEPT THE CAR FOR 10 DAYS TO REPAIR A BRAKE, HOW COME IT TAKES 10 DAYS? I BELIEVE THEY FOUND OUT THAT THE CAR HAS MORE THAN BRAKE PROBLEMS, AND THEY KNOW ALL THE LEXUS CAR HAS POTENTIAL PENDING PROBLEM, EITHER ELECTRONICALLY OR COMPUTER THAT CONTROL THE ELECTRONIC , IMAGINE IF MY CAR STALLED WHILE I WAS DRIVING ON THE HIGH WAY, FOR THE SAFETY OF ALL THE CARS ON THE STREET, YOUR DIVISION SHOULD LOOK INTO THE PROBLEM OF NOT ONLY TOYOTA BUT ALSO LEXUS AND OTHER CARS MADE BY TOYOTA MOTOR INC. *TR
