Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I noticed a strong gas smell in my garage whenever I fill up the gas tank, I took my car to Mercedes Benz dealer in houston, tx (Mercedes-Benz of houston greenway) and it was told that my tank has a hole and it leaks fumes into the surrounding that is why I smelled gas. The dealer asked for $3095 to repair the issue which will require replacing the fuel tank. I have been taken good care of my car and I don't understand why there is a hole in the tank in the first place, I believe it is manufacturer defect in the design/workmanship of the fuel system in this model

Mine is a 90000 mile vehicle showing normal wear, no abuse or no accidents, diagnosed with leaky fuel tank. Just spent $900 on fuel pump, sender and pressure sensor-all of which was to fix strong gas odor. Repairs did not abate the strong gas odor when tank is full. Independent Mercedes mechanic then diagnosed as leaky tank and stated that repairs would be about $1500. His parts man said that the part number on the fuel tanks had changed three times-indicating that he thought that Mercedes was trying different fixes. Mechanic also said that his shop has diagnosed/fixed several other with same problem. Gas odor is so strong that I believe that a tossed cigarette would ignite my Mercedes. Mechanic says that the tank is some form of "plastic" and not metal.

There is a strong fuel smell in the vehicle after filling up gas tank. Dealer found the issue associated to fuel sending unit, which seem to be a recurrent issue with this model in Mercedes. Dealer requires $1,400 to fix the issue. I have contacted mbusa to see if they can help with this repair. There has been a voluntary recall on the E class for 03-06 vehicles, however my car is an 07 model and there is no recall on this year, yet forums of Mercedes Benz owners are filled with same complaint for all E class models with chassis W211. Please investigate this issue. I understand there is an open NHTSA case PE12-001 that may be related to my complaint. Thank you for your prompt attention.

When this model is fueled to a full tank, a strong gas smell fills the car (and later the garage). This continues until the fuel burns down to 3/4 of a tank.
