After fueling up, a smell of gas occurs. Slight gas puddle forms under the car after every fuel up. Drops gas gauge down and after that no more smell of fuel but still slight puddle of gas after leaving the car parked. Noticed it about a month ago and it seems to get worse. Doesn't seem safe knowing the car is leaking fuel.

Fuel leaking to the inside of passenger compartment under access port under rear seat cushion, that's the location of the fuel pump. I made an appointment with tucson mercedes benz to inspect the car since I believed that a mercedes recall would correct the problem. I had several discussions with service advisor mark schofield and he assured me twice that the recall is in place and they would fix the fuel system defects without charge. He called me this evening and told me all about why tucson mercedes would not cover the repair, I was told the extended warranty program ended 2/21/2018. I bought the car on 4/5/18, filled it up with gas on 4/08/18 and the car was filled with fumes that night as well as in my garage. Tucson mercedes first said that the tank was leaking at the vent tube between the left and right access points. He told me that the cost would normally be $3000 but he reduced it to $2000. I asked mark how the fuel could run across the top of the tank, climb the locking ring and puddle on top of the left side fuel pump? He also told me that mercedes could not just replace a portion of the fuel system without replacing the entire fuel system, including the tank. Also, not true. He said that upon a second examination was made and there appears to be a crack on top of the fuel pump and now that's where the leak is coming from. Now his price to repair all is $770 + tax. After a few words more, the price dropped to $700 + tax. I feel that mercedes should just fix my vehicle and call it good. This learned that this car had a fuel pump installed at 59,000 miles. I missed their self imposed cut off date by about 6 weeks, not so much time for such a serious manufacturing defect to health and safety. The fumes inside my car and garage could have caused a fire or worse yet, an explosion. The problem first appeared after the first time I filled the tank.

There is a gas leak on the sending unit (fuel tank) when the vehicle is filled with fuel. This is an extremely dangerous issue, and it is common with the mercedes benz e320. I am concerned for my safety and the safety of my child who complains of the strong smell of gas while riding in the car. It leaves the smell of gas in my garage as well..

We have been experiencing fumes of gas after the gas tank is completely filled. Later the car developed rough idling. We took the car to mercedes-benz of oklahoma city where the car has always been serviced for inspection, the dealership kept the car for four days. In the mean time we received a letter from mercedes-benz of USA notifying us of extension of warranty on fuel system for up to 15 years. When we asked the dealership about it we were told they know and are following the "bulletin" issued by the company. Initially we were told there was a leak on the top of the gas tank, however the car was returned to us by replacing the fuel filter under warranty. There was no paper work so we don't know what was actually diagnosed and done. The car is still idling rough, the fuel gauge is not reading correct (though the tank is full, gauge shows 1/4th empty). We will take the car back to the mercedes dealership tomorrow. Fuel leak is a serious matter, we wish the company had taken serious steps to fix it and had informed the customers of the actual problem. Hope the federal safety agency will look into this matter.

I had a gasoline to leak in the well under the passenger seats in the back of my 2003 e320 mercedes benz. This is a serious safety hazard. About 2 weeks ago, I had to spend $1200.00 to replace a fuel pump on my 2003 e 320 mercedes benz. When will mercedes benz recall these models for fuel pump problems? They were never able to detect the problems while this car was under warranty, but now it's coming up 11 years later. Over 40 complaints have been sent to the consumer product safety commission (cpsc) about this problem, but mercedes is still saying that there are no recalls, nor do they have any knowledge of these fuel leak problems. There are also owners in other states with the exact problem, but listed below is a complaint on cpsc's website from a laurel, md 2003 e320 owner with the same problems that I'm experiencing: jul 31, 2011 - laurel, md - gasoline my 2003 mercedes benz e320, in which the fuel filters are located underneath the rear seat, had a powerful gasoline order inside the vehicle. The benz repair shop stated it was a hairline fracture in the fuel filter and it was leaking gas. They replaced the filters, but I've seen them replace the same type filters in 2008 models. I think this is a defective product and a safety hazard. If me or my spouse had been a smoker, or caused a spark, we could've potentially caused a fatal explosion. I think this needs to be investigated.

I have a 2003 e320 sedan, I can smell very strong gas fumes all in the car cabin every time I fill up with gas - not topping off, and no fuel leaking. This is so prevalent I have to leave my car parked outside instead of in my garage. This can last for around three days. I have investigated possible causes and none seem to actually correct the issue. This can be quite costly. I also have noticed many many other complaints filed for the same reason. Please help.
