This is in regard to the federal safety agency id #10033607, also mercedes benz service campaign #2009100002 dated jan 2010, for model 163. My vehicle isn't covered by above mercedes service campaign because it's v-6 model, but showing exactly the same safety problem. I've taken and attached a few photos of the problem area showing severe damage to fuel line and less so to brake line. The photos showing severe chafing between fuel line & brake line just below master cylinder. The service campaign only covers 8 cylinder models, but my 6 cylinder model is showing exactly the same chafing at the same area. I have not experienced any problem, but just noticed this issue last few days.

The computer let the consumer know that brake pads were defective, while taking the vehicle out on a test drive caliper locked up. Prior to this happening vehicle was starting in third gear, instead of first gear. It difficult to move out in traffic. Dealer/mechanic experienced the same problem, and replaced the fuel pump, and fuel line.

Based on a dealer reccomendation, I have become aware the mercedes benz has been conducting and unpublicised "campaign" to advise owners of certian of the ml series suvs of the desireability of "upgrading", at the owners expense, the fuel system including filters and lines. This is apparently in response to a number of fuel filter and fuel pump failures, ascribed by mercedes to "poor quality u.s. Fuel" these failures have the effect of immobilizing the car, without warning. These unexpected stoppages cn have very serious saftey implications if they occur in a moving traffic flow situation. Mercedes is well aware of this problem but has not directly informed owners and takes the position that it is not a saftey issue and therefore not subject to a recall. I believe that a documented problem, ascribable to faulty design or materials that can lead to a sudden and unexpected loss of power is a very serious hazard and should be corrected by the manufacturer.

1.) brake pads need replacing after 10,000 miles. 2.) fuel filter replacement requires newly designed part and additional hoses, clamps etc totaling over $300. Because previous part causes fuel leaks(?) and not available. Shouldn't mb pay for part of this??
