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.

Gas odor both inside and outside of vehicle when tank is filled to maximum capacity. Odor lingers until tank is about half empty. Inspected fuel pump/filter located under rear drivers side seat and discovered gas leakage/puddle. Gas leak is within a couple of centimeters from two electrical cable connections attached to fuel pump/filter - an imminent fire hazard. Prevailing fumes are hazardous to vehicle passengers, especially small children, and may cause dizziness while driving or loss of consciousness.

After refueling and filling the fuel tank, a strong odor of gasoline emits from the outside of the car and inside the car. After checking online, previous complaints of fuel level sending unit seal failure causing pooling of gasoline around the sending unit next to electrical connectors and directly under the left rear passenger seat. I removed the rear seat and access panel to the sending unit and discovered pooled gasoline around the sending unit. The sending unit appeared tight. I did not notice any cuts or failure to the hose, just around the sending unit itself. My local Mercedes dealer claimed there are no recalls for this condition, even though there appear to be many complaints. The dealer also told me I would have to bring my car in to be inspected by a mechanic to truly diagnose the issue.

6 disc changer door will not open. Right after bumper to bumper warranty was over, dealer said they had replaced many of them that week, but refused to fix it and it was only 1,000 miles past warranty. Before warranty was up, the dealer said the fixed gas hose recall but still smell gas after filling the vehicle. They will not look at it anymore.
