Lexus covered two other fuel pump safety issues for this make and model (2018 RX 450h), one under a manufacturer recall and one through a customer support program.

“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.”Owner report · Service Brakes · Dec 2022
