FOUND OUT THE BRAKE ACTUATOR IS FAILING AND TOLD FROM TOYOTA THEY HAVE RECALLS ON THE ACTUATOR FOR HIGHLANDER HYBRID AND PRIUS HYBRID. LEXUS STATED THEY DO NOT RECALL FOR SAME ISSUE. FEELS UNSAFE WHEN BRAKING AS IT MAKES LOUD NOISE AND GRINDS A BIT. I'VE READ FORUMS ON OTHER SAME YEAR AND MAKES CAUSING THEM TO CRASH. LOUD CHIRPING ON IDLE BRAKING AND WHEN BRAKING HARDER AND SOMETIMES SKIPPING. *TR
THE BRAKES MAKE A STRANGE CHIRP-TYPE NOISE WHEN I APPLY PRESSURE, USUALLY IT HAPPENS WHEN I AM STOPPED AND MY FOOT ON THE BRAKE. HOLDING MY FOOT STEADY ON THE BRAKE AND IT HAPPENS RANDOMLY AND OFTEN. I HAD MY BRAKES CHECKED AND THE PADS AND ROTORS ARE FINE; THEY TOLD ME IT WAS THE ACTUATOR AND WAS A KNOWN LEXUS PROBLEM. THIS HAS BEEN HAPPENING FOR SEVERAL MONTHS AND I HAVE NEVER GOTTEN A NOTICE FROM LEXUS STATING IT IS A PROBLEM.
DT*: THE CONTACT STATED WHILE APPLYING BRAKE PRESSURE AT ANY SPEED ON VARIOUS ROAD CONDITIONS, THERE WAS AN INCREASED STOPPING DISTANCE. THE VEHICLE WAS INSPECTED BY A DEALER WHO DETERMINED BRAKE FLUID HAD LEAKED INTO THE BRAKE BOOSTER RENDERING THE MASTER CYLINDER INOPERATIVE. AFTER THE INITIAL MASTER CYLINDER REPLACEMENT, THE PROBLEM PERSISTED. THE VEHICLE WAS RETURNED TO THE DEALER WHO DETERMINED THE MASTER CYLINDER NEEDED TO BE REPLACED AGAIN. THE MANUFACTURER WAS NOT ALERTED.
Brake system sets a high tone pitch indicating failure accompanied by all Brake, ABS, PS, Traction Control Lights. This is an know failure for Hybrid systems. It can occur completely random, while driving without notice. Complete brake pressure is lost with exception of a hard feel to the pedal that allows some incomplete breaking to occur and can also cause locking of the brakes at slower speeds. We replaced The brake actuator as recommended with factory new in March of 2024 Started much earlier. Problem has returned Summer of 2025.
