Fuel Delivery Problems of Mercedes Benz ML320

Recently, my 2000 Ml320 would end up cranking while starting. Took 2 attempts to get the car started up. Took my mercedes to the local authorized shop and was told that the fuel pump went out. Had the fuel pump replaced & filter & the new updated lines. Previously back in December 2005, power steering line was damaged. Serviced at same dealership. A small hole was discovered on the pipe and power steering went out. Almost made me hit the garage.

I picked this note up from a mercedes-benz interest group website, and examined my Ml320, and found this to be a true danger (ticking time bomb). Here: don't know if this has been a subject of discussion before, so forgive me if it has, I'm new here. I'm a dealership technician in southern CA, and I see a lot of the routine failures on all of the models. Most of the time, when something safety related is a repeat or common failure on a car, there is a recall or a campaign on the issue. Not this time. For the last few years, I have been seeing 163's with chafed fuel and brake lines. Now there's two very important systems on any vehicle, fuel and brakes. The typical failure is directly below the master cylinder at the foremost brake line. The only fuel line rests innocently against the line, chafing and rubbing for many miles. Now, you would think, ok, it's a rubber hose on a metal line, no big deal, right? no! the fuel line is lined with braided stainless steel, which effectively cuts into the brake line. I have personally replaced several brake/fuel line combos on these vehicles, and seen many others do the same. Any time I see it, I replace the lines, and bring it to the attention of higher-level personnel in mb, but two years from the first one I had seen, there has not been to date (to the best of my knowledge) any recognition of this failure by mb corporate. More common on ml 55, 500, 430 up to 2003. They seem to have shortened the fuel line on the newest vehicles. If I come across one soon, I'll try to take a picture to give you folks an idea of what I'm talking about. A friend worked on one out of state that had complete brake failure, and the woman driving ended up going through a stoplight. I'll check in once in a while, if anyone has any questions I'll do my best to answer them. Just a heads-up, do yourself a favor and go look at your engine 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.

Fuel line coming out of gas tank came loose and sprayed raw fuel all over back of car and onto street. Could have ignited from any spark or open flame.

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??.

On 04/24/02 my car started stalling out and not starting. It was towed to the nearest dealership. The fuel pump, fuel line, and fuel filter were repaired by 04/25/02. A terrible fuel smell took over the car and I returned it on 04/26/02. It was repaired and returned to me on 4/30/02. It started breaking down again on 05/05/02 and I took it in on 05/06/02. They had it for 10 days (until 05/16/02) and it broke down out of town on 05/25/02 where it remained for 21 days (until 06//15/02). It then broke down on the drive home (05/15/02)and I took it to the shop two days later (05/17/02, dealership closed). All of the problems are directly related to the fuel injectors, fuel pump and the entire system related to this but I have a 2 year old unreliable Mercedes Benz I am now paying to repair. I have contacted Mercedes Benz USA and they have been supportive of the service departments' repairs but I believe I have a car I can't sell, trade in or drive now and I paid $38,000. For it a year ago. Please instruct me on the best plan of action at this point.
