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. Reading all the problems with this ABS actuator pump, this should be recalled. 6/2025 per online, it is a known problem with toyota in the hybrid models. All of these units will need to be replaced, only a matter of time. Usually toyota's run up to and overr 300k miles. I planned on keeping mine around. But it is a 2007 with 189k miles on it. I am not sure I want to invest $2000.00 on just a part for a car this old! Junk yards sell used ones for $800+. Same model number and only in time that will fail. Apparently toyota has issued a new model number 44510-48061. There is also another new model 44050-48191. The replacement part (no labor) varies in price 44510-48060 new $1200.00, 44510-48061 $1350.00, 44050-48191 $2000.00

Subject: Urgent Safety Concern - Recurring Issues with Toyota Highlander Hybrid Models 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 previously reported these issues to Toyota, but the attempts to resolve the matter have been met with deflection of blame. It is imperative to note that these issues are not isolated incidents but are widely reported by other owners of the same model. **Impact on Safety:** The malfunctioning of critical components such as the braking system has led to near-miss incidents that could have resulted in severe injuries or fatalities. It is unacceptable for such critical safety issues to remain unaddressed. **Request for Action:** I urge the federal safety agency to investigate these reports thoroughly and take appropriate action to hold Toyota and its CEO accountable. The safety of countless drivers and the integrity of our transportation system depend on your prompt attention to this matter.

Hazardous safety issue. Possible manufacturer defect to electrical system on 2001-2007 toyota highlanders. While driving at high or low rate of speed, there has been many close calls of being hit from behind due to the manufacturer defect to their electrical components or wiring in specific to rear braking lights. When depressing the brake pedal the rear passenger brake lights do not come on. Light bulbs changed, fuse was checked and connectors checked. There has been multiple identical related issues reported by consumers on many blogs and forums online. Only remedy mentioned was to have the toyota dealer to replace the electrical braking component or circuitry. This should be a recall for the toyota highlander 2001-2007 on the critical braking systems on these vehicles. Why do consumers have to pay upwards of $400 to replace what appears to be a manufacturer issue. This is a accident made to happen. Also due to their poor design, the vehicle can't pass the state's vehicle safety inspection.
