What 2014 Lexus RX owners say
Brakes
The contact owns a 2014 Lexus RX450H. The contact stated that occasionally while depressing the brake pedal or the accelerator pedal or while stopped at a traffic light, there was an abnormal squeaking sound coming from the brake actuator. There was no warning light illuminated. The vehicle was taken to the dealer and the vehicle was diagnosed with a faulty brake actuator. The dealer recommended replacing the brake actuator assembly. The vehicle was not repaired. The manufacturer was notified of the failure and provided the contact with a case number and would respond within 72 hours. The failure mileage was approximately 141,090.
When I press on my brakes they make a loud roaring sound right away. Usually when brakes are about to go out its usually a squeaky noise then it will go to loud roaring noise. There has not been an indicator on the dash about any issues with the vehicle. I found it rather odd that the brakes made the roaring noise immediately. It didn't squeak at all. I would like for this matter to be looked into. There is no way there should be a brake system failure right away. The schrader valve has a crack and freon is leaking out of and the air is not blowing cold air.
