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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Customer complains of fuel smell outside of vehicle on approach. Upon entering the vehicle the smell is unbearable and causes nausea when driving. Inspected the vehicle and found the left side (driver's) fuel pump seal is leaking causing fuel to puddle and saturate inspection plate. The fuel wicks past inspection plate gasket and into the passenger compartment saturating the area directly under the rear seat. Replaced fuel pump module with seal (gasket) as well as gasket on right (passenger) side.

There is a very strong gas order in and around my vehicle when I fill the gas tank. I have avoided filling my tank more then 3/4 full due to this order. This cannot be safe. I have never experienced anything like this with any other vehicle I have ever owned.

When the gas tank is filled over 75% there is a strong fuel smell inside and outside the vehicle. If I fill less than 75% there is no problem. I have experimented with fuel levels from full ( not topping off ) down to the 75% and will have the fuel smell. The smell will cease whenever the level drops below the 75%. leak is coming from fuel pump seal / gas tank. Called multiple dealers and they acknowledged this is common problem.

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 NHTSA 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.
