Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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. …”
NHTSA complaint #11618706, filed 2024-10“Car displaying parking brake malfunction and and cruise control malfunction intermittent when using the parking break, seem that TSB (T-SB-0168-19) was open for Camay from 2018 to 2020 exhibiting the same issue but not for this car. This a safety concern since parking brake becomes disable, this issue resets after restarting the car again.”
NHTSA complaint #11466703, filed 2022-05“The car makes a Brake Squawk noise when the brake pedal is applied. The noise sometimes is unbearable. Dealer replaced the brake actuator. The noise came back after a few months.”
NHTSA complaint #11532979, filed 2023-07“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.”
