In reference to PE12-001 ongoing investigation fuel leaks. When gas is put in car, strong gasoline smell inside cabin. Brought to attention to dealers several times & was assured there was nothing wrong. In March 2011, they replaced the fuel pump as goodwill gesture since complaints were received prior to warranty expiring. In April 2012 advised Mercedes of fuel smell remained, at this time I was informed of a crack in gas tank under backseat. Fuel tank was replaced, brought car home, after filling with gas, once again strong fuel odor but accompanied by visual of fuel under auto. Mercedes now stated it was due to installation error & now was corrected. I have not picked up vehicle, do not have faith another potential life threatening "error" will not occur. How do we know if the replacement tank/pump doesn't have same design flaw, not worth my children's or my life to find out.

Check engine light came on. Smelled gas in and around car. Dealer found minor purge leak. Vehicle failed fuel tank leak test. Gas is pooling in the area under the back seat behind the driver. Small nipple cannot be replaced without damage. Recommended new fuel tank. Fuel sending unit is a disaster. Same type of system that was in the E55 amg which was recalled. Please investigate. Updated 01/28/11 according to the invoice, the fuel tank was leaking at the top of the tank around the expansion plug. Updated 02/03/11
