“2007 HYBRID ABS BRAKE ACTUATOR PROBLEM. THE PRIMER MOTOR CONTINUES TO RUN TO PRIME THE PUMP EVEN WHEN CAR IF OFF. THE HUMMING NOISE CHANGES WHEN YOU PRESS ON THE BRAKES TO LOAD KNOCKING GROANING NOISES. NO DASH WARNING SIGNS. I BOUGHT THIS CAR USED AND IT HAS ALWAYS MADE THE HUMMING NOISE SINCE I BOUGHT IT. I THOUGHT THIS WAS NORMAL FOR A HYBRID. SOMETIMES BRAKE PEDAL WOULD PUSH EASILY TO FLOOR, BUT THEN GET TIGHTER. I WOULD HEAR THE KNOCKING GRINDING NOISE. NO WARNING LIGHTS, HAD BRAKES CHECKED AND THEY ARE GOOD. THOUGHT MAYBE AIR IN LINE. THIS NOISE AND LOOSE PEDAL STARTED ABOUT 1 YEAR AGO. 6/2024 IT DID NOT HAPPEN ALL THE TIME. I ALSO HAVE A COMPANY CAR, SO I DO NOT DRIVE THE TOYOTA HIGHLANDER THAT OFTEN. NOW I CANNOT DRIVE IT AT ALL. FOR FEAR THAT THE BRAKES WOULD GO OUT. I STARTED LOOKING FURTHER ONLINE ON INFORMATION REGARDING THIS. IT SEEMS TOYOTA AND LEXUS RX 300 HYBRIDS (SAME PART MODEL NUMBER) 44510-48060 ARE ALL DOING THIS. I LOOKED UP RECALL'S AND NOTHING FOR ABS HYBRID PROBLEMS. JUST LAST WEEK ALL WARNING LIGHTS CAME ON IN MY CAR BRAKE VSC.

“Subject: Urgent Safety Concern - Recurring Issues with Toyota Highlander Hybrid Models Dear National Highway Traffic Safety Administration, We owned the car since almost new, after repeated attempts with Toyota, like others 300K customers from their own site, I am writing to file a formal complaint regarding persistent safety issues with Toyota Highlander Hybrid models, specifically between the years 2004 and 2007. Despite previous reports and numerous attempts to seek assistance from Toyota, the response has been unsatisfactory, with the company deflecting responsibility rather than providing a resolution. **Vehicle Information:** - Make: Toyota - Model: Highlander Hybrid - Year: 2007 - VIN: [XXX] **Description of the Issue:** 1) The primary concerns involve the hybrid a) BRAKE actuators failing/loosing braking power 2) the electrical inverters, which have shown a pattern of failure across many vehicles, including my own. 3) Leaky blow back from engine into intake. 4) Seat belts are not properly retracting, These failures could compromise the safety of the vehicle but also risk to the driver, passengers, and others on the road. **Previous Reports:** I have…”

“I REPLACED MY BRAKES AFTER SEVERAL WARNING LIGHTS AND CODES KEPT POPPING UP ON MY DASH. HAD THE ROTORS TURNED. BUT WHEN I RETURNED TO DRIVING MY CAR AFTER I THOUGHT IT WAS FIXED THE BRAKES WOULD ALL OF A SUDDEN JUST GO OUT THE HYDRAULIC PART WOULD GO COMPLETELY TO THE FLOOR. THE CAR WOULD MAKE A HIGH PITCHED NOISE AND THEN NO BRAKES. TOOK IT TO TOYOTA IN CLINTON TN. SAID MY ABS BRAKE ACTUATOR WAS FAILING. WOULD COST ME 2200 DOLLARS TO FIX. THIS CERTAIN PART ON YOUR CAR IS SUPPOSED TO LAST YOU A LIFETIME. I DONT HAVE MONEY LIKE THAT NOW IT WAS TAKE ME A LIFETIME TO SAVE UP FOR THE REPAIRS. VERY SCARY. THIS WOULD HAPPEN TO ME RANDOMLY AS I WAS DRIVING NO MATTER WHERE OR HOW FAR THE TRIP I WAS TAKING. DIDN'T KNOW IF I WAS GOING TO BE ABLE TO MAKE IT HOME SOMETIMES. YOU JUST NEVER KNEW WHEN. SOMETIMES IT WOULD BE FINE AND OTHERS IT WOULD BE ABSOLUTELY SCARY.”
