Brakes Failed problems of the 2001 Mercedes Benz S430

Contact states the there was complete brake failure at 23,000 miles. The vehicle was still under warranty. Service dealer stated they couldn't find what is wrong with the brakes.

The stereo's volume goes up and down. The power steering made a groaning noise when the steering wheel was turned in either direction, the power steering hose was tightened.
