After filling my car with fuel, I have notice a strong odor of gas fumes in my garage which smells throughout my entire home and inside my car. But I don't see any leaks on the floor. After the gas tank drops to 3/4 of a tank, the smell of fumes goes away. This has been going on for a very long time. I believe this is a safety issue and that Mercedes should repair it asap. Thanks. Also the fuel cap sensor constantly stays blinking as if there is something wrong with the connection to the fuel tank opening, every time I re fuel. I have even had the fuel cap replaced with a new one and the sensor in the car still comes on every day.

My E 320 has gas smell in my garage after refueling since June/2012. The smell is getting even stronger for last a few months.

- San Jose , CA, USA

Reference NHTSA action number: PE12001. There is a distinct fuel smell after filling up the tank. Do not smell inside vehicle but do smell after the car is put away inside garage. No sign of leakage under the car (puddling or drips). Goes away after fuel tank is less than full. There is no smell if you only fill to 3/4.

- Punta Gorda, FL, USA

The fuel tank cannot be filled up completely. Doing so causes the car to smell like gasoline. There seems to be a fuel leak on the tank which causes the gasoline to spill. The odor comes mostly from the back seat of the car. If the tank is filled, the car will have the gasoline odor for weeks even with the windows left open. This is quite dangerous in many ways since I have an infant who is required by law to sit in the backseat rear faced.

- Miami, FL, USA

There was a fuel leak that caused the car to smell of gas when the tank is near full (3/4) to completely filled. The fuel has not been leaking to the ground and I have been unable to pinpoint exact location. When I would go into my closed garage after the car had been parked for a while the smell of fuel is too strong to ignore. My mechanic told me the source is the sending unit and tank assembly. He told me the failure was common and the situation could become very dangerous if ignored. The cost to replace the tank is going to run $2,000. The car has never been damaged and should not require a tank replacement at this point in its lifecycle.

- Campbell, CA, USA

I have noticed strong gasoline odors emanating from my car after refueling. I purchased a new Mercedes Benz gas cap and installed it. Filled the gas tank and gasoline odor was still very strong. I do not 'top off' when refueling. Researched issue online at benzworld.org and discovered that the gas odor issue I am experiencing may be related to a problem being seen in numerous Mercedes Benz E-model vehicles. As advised by the other owners having this issue I detached the rear seat cushion from the car and removed the bolts from the circular access panel that covers a portion of the fuel tank on the driver's side of the vehicle. In the depression on top of the gas tank where numerous electrical wires attach to the fuel pump I found a significant quantity of raw gasoline pooled. This presents a very unsafe situation and I am no longer willing to park the vehicle in my garage due to the potential fire hazard. The pooling of raw gasoline also represents an environmental issue due to the evaporation and creation of toxic fumes. I understand that Mercedes Benz dealers are demanding $2,000. Or more to rectify the problem by removing and replacing the gas tanks in impacted vehicles. I feel that the manufacturer of this defective component should be held responsible to recall it and replace it. I understand that the NHTSA's current investigation action no. For this issue is PE 12001.
