: the contact stated while driving 40 mph the vehicle hesitated. The smell of gas was present when parking and a puddle of gas was noticed under the vehicle. An independent repair shop inspected the vehicle and determined the wiring harness of the fuel pump melted and replaced the fuel pump. The dealer was contacted.

This is experienced by most of the ml drivers: While driving the car, the car just stops and here is what Mercedes said and what happens according to mb research: The gas inside some underground tanks dissolves the protective liner. The liner ends up as a gooey substance in our tanks. As long as the pump is running there is no problem. After shutting down, the substance hardens inside the pump and freezes it. Have someone hit the bottom of the tank with a big hammer while someone else is starting up at the same time and most likely you'll get the vehicle running again - then drive to the dealer as soon as possible to get the pump replaced. Frozen pumps sent for evaluation to stuttgart did work when they arrived there without the presence of gas the "glue" had hardened to a point that it got brittle and the pumps worked again.

Car would crank but would not start. Brought to dealer they changed the fuel pump, fuel lines, fuel filter, and cleaned fuel injectors. Picked up car, worked fine for a couple of days then same problem happend again. Called dealer for a tow. Because at the time I was to drive to dealer the power steering went out making car inoperable. Dealer said the clamp that connects to the power steering hose came loose causing the power steering fluid to leak out. That problem seems to be fixed. My dealer addressed my original problem by thinking that my keys to the car were triggering some kind of antitheft device in the cars computer to keep it from starting, they gave me two new keys, worked fine for about 30 miles when this time while actually driving the car went completely dead, I was glad to be in a turn lane at the time. The two previous times it took about an hour for the car to restart this third time it took only about ten minutes. The dealer still remains baffled.

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.

Would be driving vehicle when it would stop suddenly without warning. Was at gas station & had turned vehicle off & put fuel in vehicle. Had tried to restart vehicle which did not start. Took to dealer. Fuel pump would go into a vapor lock. Fuel is not getting to proper channels. Fuel pump has been replaced twice for same problem.
