This isn't a complaint, it is a request for consideration of or assistance for the replacement of the gasoline tank for my vehicle. When I took ownership from the previous owner, the first time I filled up the gas tank, the vehicle was emitting a strong gasoline odor. I took the vehicle to the Mercedes Benz certified service representative here because this is where the previous owner always had this vehicle serviced. There were no records showing this problem being looked into, and when I asked the previous owner, he said he never filled up the gasoline tank, always putting in $15 - $20 or so at a time, therefore he never smelled the gasoline odor. The Mercedes Benz certified service representative informed me that this model along with 2005 and 2007 models had similar problems with the gasoline tanks. I then took it to our Mercedes Benz dealership here and talked with a service representative. He was very, very helpful, very knowledgeable, and told me there were problems with this issue on these models, but no vehicles had been recalled. He told me how much it would cost to have the gasoline tank replaced (worse case scenario) suggested I write to you and see if you would consider replacement or assistance. It is my first Mercedes Benz to own and I love this vehicle. I am a retired minister living on social security, so anything you could do for me would be prayerfully appreciated. Would you mind looking into this and assist me with this problem? thank you very much.

On gas filled up, the entire garage smell of strong gasoline smell that can cause nausea and dizziness if garage door is not opened to allow fresh air, mechanics said there is a leak in the fuel system and similar car owners have the same issue. Smell will go away when the fuel level is below 7/8 level. I started having this problem at around 40,000 miles and currently around 48,000, I hardly use the vehicle due to the smell and safety concern. Mercedes should recall this defects for epa, safety and health concerns before any incidence and resulting class action lawsuit.

Whenever gas tank is filled, strong gasoline smell persist around car until fuel level drops to 3/4 level. If car is parked in a garage, entire garage has extremely strong gasoline odor. Car was taken to the dealership and dealer advised that fuel tank has a leak with no safety recall. This is a serious fire hazard and after searching internet I found out that hundreds of users have reported exact same issue. Mercedes should fix this issue for free.

Mercedes E350 2006, has bad odor of gas. I noticed after filling up gas, and parked my car in garage in the morning my whole garage had a smell of gas. I looked around underneath and every where inside outside I don't see any leak of gas. I can just smell gas fumes... I have called Mercedes dealer haven't heard anything back and I research web and found so many other cars of Mercedes have this problem.. I hope this can be recall and fix.

The contact owns a 2006 Mercedes Benz E350. The contact stated that after refueling the vehicle, a strong odor of gasoline was emitted. The odor would dissipate once the amount of fuel within the tank dropped below three-quarters full. The vehicle was taken to an authorized dealer where the fuel tank was lowered. The failure continued. The vehicle was taken back to the dealer where the contact was informed that there was a faulty gasket on the fuel sending unit. The gasket was replaced, but the failure continued. The vehicle was not taken back to be repaired a third time. The manufacturer was not made aware of the failure. The failure mileage was 40,000.

Car's (Mercedes Benz E350 sdn 2006) fuel gauge showed that the tank was half full. About ten minutes into the drive, the vehicle decelerated automatically from 65 mph to 0 mph. Police were called to prevent a pile on crash. Towed car to dealer who found that there was a gauge malfunction. Replaced gauge. Two months later, the very same problem recurs. Leads me to believe that the fuel gauge is unreliable can create a safety issue especially in freeway driving, the vehicle has been in the shop four times in the last three months to fix these issues. While fixing the sensors, the car had a distinct gasoline odor especially when tank was full. The dealer did a smoke test and concluded that the tank was leaking and had to be replaced. Now, with a new tank, and new sensors for fuel supply, the exact same problem re-occurs. I am very concerned about the safety implications of a fuel gauge malfunction. Please note that the fuel safety light in never triggered when the gauge malfunctions so the driver has no way of knowing that the gas is running out. Updated 01/13/11 uddated 03/24/11
