2019 Lexus Rx

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.

Codes P219C & P0301 have continuously came on , these lights MIL have made the vehicle go from AWD to 2 wheel drive while in motion. [XXX] vehicle was taken to Bay Ridge Lexus. In brooklyn NY. They over looked this issue and stated it was something else. This has been confirmed via multiple diagnostics machines. Lexus of Edison has also decided not to cover this repair under warranty . The danger of going from 4 wheel drive into 2 wheel drive while in motion is extremely dangerous . These warning lights/MIL once activated has also caused the vehicles sonar to fail cause a serious safety issue. My vehicle is available to be inspected as needed.

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.
