   Brake actuator makes a shriek when I engage the pedal. Problem is ongoing and applies to 2015-2019 Lexus RX450 Hybrid models. Problem is getting worse, and I am afraid of brake failure. Lexus has been repairing this problem, gratis, for owners under their Customer Support Program 23LE04. I contacted Lexus and was told that Hawaii-based Lexus Vehicles are part of the Japan Dealer Network and to contact them. I made an appointment and the car was inspected on April 16, 2026. The outcome was that Lexus of Hawaii/Japan will not repair my vehicle unless I pay $4,000 for a new brake booster pump assembly /labor. Lexus of N. America is covering this repair for 10 years or 150,000 miles, but they refuse to honor it here in Hawaii.

   My Lexus 2019 RX450H is making a squishing squeaking brake actuator noise when pressing the brake pedal. I located well publicized TSB’s documenting the awareness by Toyota/Lexus of the problem. (TSB: MC-10245447-9999) Brake Squawk/Knock Noise. I checked with my local Lexus dealership to see if my vehicle had been repaired. It had Not!. Temecula Valley Lexus, 42081 Dealer Drive, Temecula, Ca. 92591. (951)365-6834. I scheduled an appointment for repair on 1/26/26. They rejected making the repair because my vehicle DID NOT have any codes in the computer OR any lights on the dash. They did in fact, confirm the brake actuator noise. I reject that concept because WHO could know ahead of time if a part experiences a (1st time) total failure without throwing codes and turning on dashboard lights? As I read the symptoms of severe problems experienced in a higher level of failure by brake actuators, I would not want to have to experience a crash accident in which the actuator would operate correctly in a hard stop condition or have ABS failure and brake lockup occur. Personal harm and property damage should not have to be an indicator if I can have the manufacturer cover a repair. Please advise What I should do to increase the response in the direction of getting this known problem repaired.

   I was dropping my husband off at cardiac rehab. I was stopped and had my foot on the brake suddenly the car launched forward into the back of a car parked in front of me. The other driver got out of the car and said he wasn't hurt. We were able to drive the car home stopping 3 times to pull pieces of the car off that were dragging on the road. We took the car to a mechanic at the end of the road. He scanned the codes for us. Pre-collision 2 ClAll ; Intuitive Park Assist ClAll Front Sensor Comm. Circuit ; Front Recognition Camera ClAll ; Lane Keeping Assist ClAll Front Radar Sensor Incorrect Axial Gap ; BCM B124B Light Source Sensor Open/Short. The insurance adjustor totaled the car and they picked it up today. No warning lights showed up on the dash until after the accident.

   I am reporting a safety-related violation. The dealership told me the vehicle had only a minor accident with no airbag deployment. This was false. Carfax shows the vehicle actually had a major accident with airbag deployment, which they failed to disclose. This misrepresentation affects the safety system, airbag sensors, and the ability of the airbags to function properly in future collisions. This nondisclosure is a serious safety concern and fraudulent practice. I am requesting NHTSA to review this as potential safety fraud involving failure to disclose a prior airbag deployment.

   Brakes making honking sound when applied even when stopped. My brake actuator is failing and has been confirmed by the LEXUS Dealership. Noise and stiff breaks has been going on for a while. There is no recall, but Lexus put out LSB to dealerships May 15, 2023 and revisions earlier. This information should be provided to owners IMMEDIATELY, if the actuator fails, this is a safety issue.

   For some unknown reason the car will suddenly display multiple warning lights, check engine, service needed, traction control off/inactive then the car will go into reduced engine power mode which prevents acceleration and causes the car to feel like it’s going to stall or shut off. This has happened several times on major high speed highways causing other cars to slam on their breaks, drive recklessly to avoid my failing car. My daughter has been in the car several times when this happened and it took everything in my power to not collide with another vehicle. We have taken the car to the Lexus dealership every time and they have tried to fix the car over a dozen times but it keeps happening. They don’t seem to know the issue or cause, trying several different solutions. How can a car manufacturer not know what is wrong with their own car not how to fix it? What am I supposed to do, just keep driving it and pray an accident never happens? There is no warning when this happens and no way to keep the car from swiftly decelerating or keep the car from using “minimal engine power” which I’m to,d is to protect the engine but I’m more worried about us. The date below is for the most recent incident.

   My vehicle has an intermittent check engine light along with an ICS malfunction code that pops up on the dashboard. The car doesn’t want to turn on after every gas fill up. After taking my car to a couple of independent shops, they determined that the issue with the car was the high pressure fuel pump. The suggested, I take it to the dealer as there was TSB bulletin on it. Furthermore I still had the letter from Lexus stating the issue. The local dealership refused to do the work and suggested other work after charging a huge amount for the car inspection. Lexus Corp wouldn’t help on the matter. There are 4 other complaints on this same issue and the dealers and the Plexus Corp are getting away with not calling this an actual recall because the government hasn’t stepped in.

    I’ve approximately the last 45 thousand miles, Lexus dealers have replaced the brake actuator and other components of the brake system on this vehicle at least 6 times due to noise issues. Lexus has stated that this is not a safety issue, I have an open ticket with Lexus, but yesterday I had to slam on the brakes and did not get nearly the response that should have come right away. There are no warning lights, as far as I can tell the traction control didn’t engage, and eventually the car suddenly started breaking much harder, but it was very delayed l, and disproportionate with any additional force applied. Lexus knows the brake system is an issue in this model to the point where they are covering the system for 10 years or 150,000 miles, but to say that it isn’t a safety issue seems short-sighted. This system works in conjunction with the radar sensors adaptive cruise control, and I’ve had. This car has also had a number of seeming electrical issues, with every door lock actuator replaced at least once, some of them more than once, and the infotainment system shuts down and reboots randomly or freezes.

    AC doesn't work properly. We had several incidences when we were driving from Houston (TX) to Dallas (TX) in hot summer. The AC worked well when we left Houston, however it stopped blowing cool air when we were in the middle of nowhere on highway. The air became warmer and warmer, and there isn't anyway that we can adjust the air volume nor to cool it down. We took our car to Lexus dealer for diagnosis and nothing unusual was detected. The dealer suspect the cool air clogged in condenser that blocked cool air from entering the cabin. This is truly a safety concerns to all Lexus owners. When we drive on highway, in the middle of nowhere in hot summer, the car cannot provide a comfortable environment to driver and passengers, especially for babies or older passengers. It's a safety design flaw with Lexus RX350.

    At the initiation of braking effort by pressing the pedal, there is a noise. This noise goes away completely beyond a point of compressing the brake pedal and even before complete braking. Lexus dealer said it was brake actuator. Repairing it is labor intense and costs $3800. However not a safety concern and can be driven. He did offer to do regular maintenance of topping off fluid, multi-point inspection, tire rotation package. I saw there were recalls and complaints about the same problem with other year's Lexus models. Can you investigate this and let us know if we can avail a recall fix for this? Thank you for your time.

    On december 28th , 2022, i was giving a ride to a collegue of mine. She opened the door and got in . I proceeded to get the car out of park and suddenly the car accelerated and i could not get the car under control. I turned the car so it would not hit the structure in front of me. I turned but still could not control the car and the only way was to put the car in to park . It jumped the curb and stopped. The Left side door opened in the process and was open as this happened.

    Lexus 2019 RX350 driving down hill with adaptive cruise control on tries to keep speed set at 72mph but as going down hill car gains speed so adaptive cruise control applies brakes to slow down. After 1-2 mile of downhill driving the car starts to vibrate severely until ADC is turned off allowing brakes to cool. Brakes seem normal as they slow car down without the vibration. Engaging ADC starts the whole process over again while going down hill. ADC does not cause vibration if on normal level or slightly downgrade sloping road.
