2007 Toyota Highlander

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

My vehicle about a year ago started to display the dash lights for the VSC, ABS, and Emergency Brake however there was no indication from the feel of the brakes as they were applied, or any indication that something was wrong with the vehicle. I had my brakes replaced on my rear tires, and for a time the lights went off. In April of 2025, the lights came back on however this time there was a distinct feeling that the brakes weren't working. I had the calipers, pads, rotors, and a tube replaced, however the lights are still on, and the vehicle now violently shakes after reaching speeds of 45 mph (mirroring the complaints from the following site: [XXX] ). Toyota has refused to acknowledge this and put consumers out thousands of dollars. This is clearly something toyota needs to honor.

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 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 NHTSA 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.

While driving a vehicle came across me and when i pressed on the brake hard, the car would stop normally, and ABS, brake, VSC came on the display along with a high pitch sound. I quickly reacted by pressing the E-Brake and shift to B - braking mode to be able to stop or slow down. The dealer said it was the Brake actuator that failed and its out of warrant, there was an enhancement warrant program that was issued by Toyota but expired. I feel the safety of people and property that this should've been a recall knowingly it can go out anytime. Contacted Toyota Corp. and they said this would be an out of pocket cost to the consumer which is around $3000. The manufacturer knew this could go out at any moment and should've made the RECALL instead. during the enhancement warranty program they would not replace it since it was still functioning.

Driving at about 50 mph on two lane road, the VSC and ABS lights come on with a little chime warning, along with some other warnings. Check VSC is also in the small screen instead of the odometer. Toyota knows about ABS actuator issues on this vehicle, but Toyota did not extend the warranty beyond 150k miles and 10 years. This could be a safety issue with the ABS, VSC and brakes. Toyota published a "Warranty Enhancement Program - ZG1" on April 19, 2016, but only to dealers. After the initial warranty period, I've used independent repair shops, so I didn't get any notice. I did get other recall notices from Toyota on this vehicle and had them repaired by the dealer. Toyota should be more accountable for brake issues that could be safety related.

All of the sensors for tires were removed before I bought this car and the tire light keeps on(the pressure is good). My friend said they might adjust the mileage, I wonder if there is something wrong with this car. There was only one break working while getting this car, the mechanics from other maintenance store found this critical issue out while I asked them to fix the working one. Nobody from that car dealer told me about this issue and let me drive this car with only one break for one month. Meanwhile, they promised me there would not be any safety issue and charged me for safety checking. Thank you for your time on my case.

While driving down the 405fwy downhill, all my lights went off and showed VSC system on my dashboard. This part of the fwy is not extremely steep but somewhat is. When applying my brakes it was hard to get my vehicle to stop especially because I’m on a freeway and when trying to slow down because I’m going downhill. I had my family in the car. I can’t imagine if my my brakes actually gave what would happen. I researched this and Toyota only called this a “warranty extension” for your Brake Actuator. I can’t believe this hasn’t been classified as an official recall. Especially since it pertains to the brakes. An essential quality mechanism to prevent death. They obviously know they were in the wrong here since the warranted this as a “warranty extension”. All these vehicles should be recalled for human safety. Shame on them.

we were station in the Military base in Belle chasse LA. I'm having a SAFETY issue with the vehicle brake system and ABS.I contacted Toyota and nothing was done this vehicle has like 76000 miles and this a mayor concerned, and safety issue I believe this is a factory problem from day one. I have read thousands of same complaints on line with same problem. I also read that Toyota had the same issue with Prius and my understanding is that it was a recall on those. My car is low in millage for the year and I have been the only owner. This is a safety issue and I need help I'm very concern for our safety and others . Thank you, and your attention to this matter is appreciated.

The 2007 Toyota Highlander Hybrid and certain Prius and Lexus models were equipped with an ABS actuator that could potentially fail and cause serious injuries and or death. A safety notice and enhanced warranty covered the parts and labor 10 years later; however, after the 10 years was up, the owner would be responsible for the all the costs. I noticed the vehicle making erratic noises from the engine bay and discovered it was the brake actuator but no warning lights or significant braking issues were of concern around 1/5/22. On 1/30/22 I was driving the vehicle when suddenly multiple lights came on which include the VSC, ABS, Brake, warning light, and exclamation warning light came on. The vehicle started acting erratic with unusual power loss and poor braking responsiveness. This also occurred on my 2005 Toyota Prius which I got into an accident in where the vehicle was totaled. This part should last the life of the vehicle, and if replaced in the past due to safety concerns under the enhanced warranty, all vehicles with the same old part number should be recalled and replaced at no charge to the owner.
