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…

My Lexus 2019 RX450H is making a squishing squeaking brake actuator noise when pressing the brake pedal. I located well publicized TSBâs 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…

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…

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.

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 itâs 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…
