“I am writing to raise a serious concern regarding a issue with my 2018 Lexus RX450hL involving the brake actuator. Since purchasing the vehicle at 63,000 miles, I have noticed hissing, clicking, and squeaking noises when applying the brakes. As the mileage increased to 83,000, these noises have worsened, becoming unbearable. In addition, I am experiencing a shaky driver-side mirror and a rusting hood latch, both of which present safety concerns. For a vehicle under 5 years old , I believe these problems do not reflect the quality I expected, particularly given the premium price I paid. According to Lexus' Technical Service Bulletin (TSB) #L-SB-0032-23 Rev, issued in October 2023, which addresses squawk or knock noises from the engine compartment when the brake pedal is pressed or released, affecting models like the RX450hL. My vehicle exhibits symptoms similar to those described in the TSB. The vehicle was regularly maintained by the previous owner at Lexus of Thousand Oaks and Woodland Hills. Despite this, the major part like brake actuator has failed prematurely. Given Lexus' reputation as a luxury brand, it is unacceptable that such a critical component would fail before the vehicle is 5 years old or has reached 100,000 miles. The combination of the brake actuator defect, the shaky mirror, and the rusting hood latch is disappointing, especially for a vehicle of this caliber. When I initially contacted Lexus Customer Service, I was also dealing with rusting parts and a failing brake booster. Lexus of Cerritos provided a repair estimate of around $5,000 for brake actuator. I was advised to reach out to Lexus Customer Service after my request for a good faith repair was denied due to the inability to obtain the complete maintenance history. However, I have since confirmed with the previous owner and Lexus that the vehicle was regularly serviced. I am also aware that Lexus has issued brake actuator-related recalls for several models.”

“Lexus 2018 Rx450hl is known to have issue with brake actuator. A faulty brake actuator causes the car to fail sudden stop. It’s definitely a safety issue. Lexus have technical service information bulletin(tsib) for this issue since 2019. They never contact the owner to replace the faulty part. So if the car is under warranty they will fix the problem with no cost. But if the warranty pass the threshold, they are charging the costumer 3.5k to replace it. It’s an absolute horrible business practices. This part is a manufactured defect and it’s a safety issue.”
