1 Brake Fluid Leak problem of the 2009 Mercedes Benz ML350

Failure Date: 09/15/2017

My rear brake lines have corroded to the point that I lost my brakes. The fluid has leaked out. The car is not rusting or showing signs of rust or corrosion. Only the actual brake lines have rusted. It appears to be a defect in manufacturing. The lines should have had a protective coating or been covered in the exposed area to prevent excessive corrosion to the point the brake lines rusted thru and the vehicle lost it's braking ability. This happened while was in stop and go traffic so luckily nobody got hurt but if I was at a high rate of speed I would have lost my braking ability and it could have been much worse.

2 Brake Fluid Leak problem of the 2004 Mercedes Benz ML350

Failure Date: 07/06/2012

While driving on a local street, I noticed that brakes had stopped working. After investigation, I noticed that a corroded brake line was leaking brake fluid. I had contacted Mercedes Benz customer service. I was told to contact a dealer, who confirmed that all brake lines are corroding in the area close to the engine compartment. I was told that this is not a safety issue subject to a recall. I was further told that it is normal for brake lines to corrode and leak. I have not noticed corrosion on any other part of the car, except the brake lines.
