Consumer Description

Corroded brake lines. This is a well known issue for many ML350s built during this time period. This car was built with steel brake lines that easily corrode and present a serious safety issue. While driving a few months ago, the car suddenly lost the ability to brake because a line rusted completely through. The mechanic noted the lines are rusted in many other places as well. Mercedes refuses to correct this under warranty.
