Six problems related to fuel pump have been reported for the 1999 Mercedes Benz ML320. The most recently reported issues are listed below.
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.
Vehicle was shutting off and burning a lot of gas. Consumer was going on a trip, and dealer checked vehicle the day before the road trip. Consumer was 100 miles away, and vehicle cut off. Vehicle was towed to nearest dealer. Cause still cannot be found.
Consumer states fuel pump failed three times.
Vehicle has a faulty fuel pump. The consumer received a recall letter regarding the power steering, however the consumer did not state if the vehicle experienced a failure.
Vehicle has experienced a no start condition. Dealer has replaced fuel pump twice, but defect still occurs.
