On thursday october 23, 2014, I took my 2004 e320 sedan to schumacher mercedes benz in scottsdale arizona. I asked them to check out a 'check engine' light and informed them that there was an occasional strong odor of gasoline. On friday october 24, 2014, the dealership called to inform me that the gas tank and sensors needed to be replaced because of a leak. My service coordinator also told me that it is a common / known problem with the make and model of my vehicle. The cost to repair it would be $4000 + I contacted the federal safety agency website and learned that there is an open investigation and a complaint opened march 15, 2013 ,,, however there has been no recall issued as of this time. The car has not yet been repaired. On october 24th, I took it to a repair shop who works exclusively on mercedes benz vehicles, for a second opinion / evaluation.

I left my home in cincinnati, oh at 8:25, with a 1/2 tank of gas, drove ~ 3 miles to hwy126 and merged to 75s. I moved from the right to the middle to the left lane. After being at 50 MPH ~ 2 minutes on the left lane, the car suddenly stopped. The dashboard was all lit up with warning signs, check engine, brakes and oil. I put my hazard light on, put the car in park, turned the key off, and then back on. The same warning signs came on and the car did not start. I called mercedes assistance who advised to call 911 and that a tow truck will arrive in 1 hour. I called 911 and surprisingly got a voice message that all operators are busy! A minute later an operator came on the line, she asked where I was and I told her that I was on the left (high speed lane). She asked me if I was in a black mercedes. She indicated that a dispatcher is on the way. At 8:51 I called aaa to get a towtruck earlier. They said they will come in 45 min. A car assistance van came and eventually the police car. They stopped behind my car, and tried to turn the car on and were unable to, they asked me to put it in neutral but the gear would not move. The policeman stopped the traffic on the highway, asked me to step out of the car while he managed to put the gear on neutral and asked me to sit back in the car and steer. They manually pushed the car to the right shoulder but I was not able to steer as the power steering was not working. At 9:18 the aaa truck came and towed the car to the mercedes dealership. They diagnosed the problem as a sudden failure of the crankshaft position sensor and replaced it for a charge of $463.46. I found on the web that several mercedes models have had this problem occur but there has never been a recall. The sudden complete failure of a car in the midst of rush hour traffic creating a major hazard to me and other drivers needs the attention of the federal safety agency.

I own a 2004 e320 with only 44,652 miles. After every fill up strong order of gas from left side near back seat area also check engine light will always comes on. I took car to a mb mechanic trained by mb he removed the rear seat and left fuel sending unit cover , found a huge puddle of gas on and round gas tank pump area. I was told the pump seal was no good, I had the pump and seal replaced, filled tank again with the same result. Finally, last friday, with the seat and sending unit cover off we filled the tank and drove the two miles back to the mechanic shop, when we arrived the whole area around the pump was full of fuel, upon inspection one could see the fuel running from the top of the fuel tank and puddle around base of the fuel pump. We video the fuel running from top of the fuel tank. Contacted local mb dealer where I purchased the vehicle but was told there is no warranty on vehicle. The dealer will inspect and repair the vehicle but the expense will be on me. I don't allow anyone in my family to drive this car because of this problem. This is very dangerous situation that needs to be address.
