Exactly appearance as in consumer complaint: odi case number: 10311317. I am writing to let people know that I have resolved an issue myself because I know that nether dealership nor private mechanics would not have sufficient time to properly troubleshoot an issue. I would guess that there is a design flaw in tolerances between guides of brake pads and cylinder slots. Pads are too tight sitting in cylinder, causing excessive force to brake and getting them almost get stacked close to rotor. This causing uneven rotor worming, vibration and humming sound. It is really dangerous. Using grinder I have reduced the size of pad guides. 2 minutes of work. Issue is gone and never recurred.
When I was driving the vehicle it started to make a rumbling and rattling sound in the rear of the vehicle. I notified Toyota corporation and they flat out refused to assist me or offer any "good faith" measure or any service whatever to assist me with the defect. The rear passenger wheel bearing hub assembly was leaking and was not detectable when the car was taken for services and inspection.
