2019 Lexus RX Driver assistance Problems

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.

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.

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.
