IT STARTED HAPPENING A FEW MONTH'S AFTER I PURCHASED THE CAR. I DIDN'T THINK OF IT MUCH BECAUSE IT WAS VERY FAINT AND NOT LOUD AT ALL. THE NOISE WAS GETTING LOUDER INCREASINGLY BUT SLOWLY. THE BRAKES WORKED FINE SO I LET IT GO. LATER ON, IT STARTED BOTHERING ME EVERY TIME I PRESS THE BRAKE PEDAL. THE SQUAWKY NOISE BECAME REALLY ANNOYING SO I TOOK IT TO THE DEALER WHERE I PURCHASED THE CAR. THEIR SERVICE PERSON DIDN'T THINK IT WAS A PROBLEM AND DIDN'T WANT TO TRY TO INVESTIGATE THE ISSUE. A FEW WEEKS/MONTHS (NOT SURE HOW LONG) LATER, I TOOK IT TO ANOTHER DEALER AND THEY CONTACTED LEXUS AND DECIDED TO FIX IT. WHEN I PICKED THE CAR UP, THE NOISE WAS GONE AND I WAS HAPPY FOR A WHILE. AFTER A FEW MONTHS, THE SQUAWKY NOISE STARTED HAPPENING AGAIN. IT WAS VERY NOT LOUD, SO I REALLY HOPED THAT IT WOULDN'T GET ANY LOUDER THAN THAT. THIS TIME, THE PROGRESSION OF THE NOISE WAS SLOWER THAN THE FIRST TIME. I WAITED SOME TIME TO TAKE THE CAR FOR A SCHEDULED MAINTENANCE. I MENTIONED IT TO THE DEALER WHO FIXED IT. THEY WERE LOOKING FOR A LOUD NOISE THAT IS CONSISTENT, WHICH THEY DIDN'T HEAR. I WAS TOLD THAT IT WAS SOMEWHAT NORMAL FOR A HYBRID CAR, SO THEY CAN'T DO ANYTHING SINCE THERE'S NO SAFETY ISSUE. YES, THE BRAKES WORKED FINE, BUT THE BRAKE HAD BEEN MAKING THE SQUAWKY NOISE NOT SOON AFTER I FIRST PURCHASED THE CAR! LEXUS ADVERTISES LIKE THIS: LEXUS EXPERIENCE AMAZING. THE SQUAWKY NOISE IS NOTHING CLOSE TO AMAZING WHEN YOU DRIVE A CAR THAT MAKES A NOISE LIKE MY 2018 LEXUS RX450H. ANYWAY, I WAITED ONE MORE SCHEDULED MAINTENANCE. THIS TIME, I COMPLAINED THAT THE NOISE IS GETTING LOUD AND I CAN'T STAND IT. THIS TIME THEY CONTACTED LEXUS AGAIN, BUT LEXUS TOLD THEM THEY DON'T HAVE TO FIX IT BECAUSE IT WAS NOT A SAFETY ISSUE. SO BASICALLY I'M STUCK WITH A CAR THAT SQUAWKS ALMOST EVERY TIME I PRESS THE BRAKE PEDAL. THE ATTACHED DOCUMENT IS THE EXACTLY MY PROBLEM AND I NEED HELP.

MY 2013 RX450H' ABS LIGHT SUDDENLY TURNED ON WHILE I WAS DRIVING IN A LOCAL ROAD. ALONG WITH THE ABS LIGHT, THERE WERE BRAKE WARNING LIGHT, MASTER MAINTENANCE WARNING LIGHT, SLIP LIGHT ON ALONG WITH "CHECK ABS" "BRAKE SYSTEM MALFUNCTION" WARNING MESSAGES APPEARING ON THE DASH BOARD. VERY UNSETTLING. I TOOK THE CAR TO A LEXUS DEALERSHIP AND THEY RETRIEVED ERROR CODE AS "C1391, ABNORMAL LEAK IN ACCUMULATOR. " THEY DIDN'T DETECT ANY LEAKAGE OR MOISTURE IN THE DIAGNOSIS, THEY RECOMMENDED TO REPLACE THE ABS ACTUATOR AND BOOSTER BUMP/ACCUMULATOR ASSEMBLY FOR A PRICE OF OVER $4300. AFTER I DID SOME RESEARCH OF THIS PROBLEM, I RAN INTO MANY COMPLAINT OF THE SAME ISSUE WITH VARIOUS TOYOTA AND LEXUS CARS, ESPECIALLY ON HYBRID MODELS. I ALSO LEARNED THE FAULTY COMPONENT IS THE ISSUE AND THE ISSUE HAS BEEN THERE ON MY CAR FOR A LONG TIME WITHOUT MY REALIZING IT. BECAUSE 1) THE ABS ASSEMBLY WOULD MAKE THE CHIRPING SOUND WHEN I START THE CAR. SINCE THE SOUND ISN'T LOUD, I WASN'T AWARE IT WAS ANY INDICATION OF A PROBLEM. 2) I ENCOUNTERED AN EVEN MORE SERIOUS SYMPTOM OF THIS ISSUE MANY MANY TIMES. WHEN I PUT THE GEAR ON REVERSE SHORTLY AFTER I SWITCH ON ENGINE, EVEN WHILE I AM STEPPING ON THE BRAKE, THE CAR WOULD JUST MOVE BACKWARD, OUT OF CONTROL OF THE BRAKE. I HAVE TO RELEASE AND REAPPLY MY FOOT ON THE BRAKE TO STOP ITS MOVEMENT. I FAILED TO RECOGNIZE THAT THIS IS THE SYMPTOM OF A FAILING ABS ACTUATOR EARLIER, AS I THOUGHT IT WAS SOMETHING THE HYBRID MODEL HAS WITH ITS ELECTRIC MOTOR KICK IN INSTANTLY. I ALSO LEARNED TOYOTA/LEXUS OFFERED CUSTOMER SUPPORT PROGRAMS FOR THIS SPECIFIC ISSUE ACROSS MANY MODELS AS DETAILED IN THIS POST HTTP://WWW.DIY-TIME.COM/AUTOMOTIVE/TOYOTA/FAULTY-BRAKE-ACTUATOR-BRAKE-BOOSTER-PUMP-ON-TOYOTA-LEXUS-CARS/. LEXUS SHOULD ISSUE SWEEPING RECALL TO ADDRESS THIS PREVALENT ISSUE IN ITS PRODUCTS. THE ISSUE WOULD LEAD TO REAL SAFETY ISSUES FOR DRIVERS.

TL* THE CONTACT OWNS A 2006 LEXUS RX400H. WHILE DRIVING, THE BRAKE PEDAL BECAME VERY DIFFICULT TO DEPRESS AND VIBRATED WHILE BEING DEPRESSED TO THE FLOORBOARD.

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.
