SERVICE BRAKES

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.

ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE

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.

AIR BAGS

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.

UNKNOWN OR OTHER

While driving roof glass just exploded. Sounded like gun being fired. No one was around us and glass blew outward. Almost had an accident from the explosion.

SERVICE BRAKES

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.

ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM

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.

FUEL/PROPULSION SYSTEM,FORWARD COLLISION AVOIDANCE

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.

Unintended acceleration causing accident March 2, 2023. Low speed frontal collision avoidance assist did not engage causing accident June 11, 2024. August 2023 I agreed to video and Lexus is not providing video of accident June 11th, 2024! Recall on fuel pump and software replaced but still BAD. Radio off.
