One problem related to brake hoses, lines/piping, and fittings has been reported for the 2006 BMW 525. The most recently reported issues are listed below.
The brake lines rusted through and lost fluid very quickly as I was driving. I was able to make it to a garage, driving very carefully. Why are the brake lines made of a material which rusts? the garage told me the vehicle was unsafe to drive until the brake lines were replaced. The cost was $491. 88.
