20201026FUEL/PROPULSION SYSTEM
I INHERITED THIS VEHICLE FROM MY FATHER AND WHEN I FUEL UP THE SMELL OF GAS IS OVERPOWERING. I CHANGED HOSES AND GASKETS IN 2018 AND WAS OK UNTIL 3 MONTHS AGO. NOW IT ALWAYS SMELLS LIKE GAS TO THE POINT OF LIGHT-HEADED AND VOMITING. CALLED MERCEDES THERE WAS AN ACTIVE RECALL THAT EXPIRED IN 2019 BUT I HAD NEVER RECEIVED NOTICES AND SPOKE TO MY MOTHER THAT ALSO NEVER RECEIVED. MERCEDES ADMITTED THEY HAD INCORRECT ADDRESS SO THEY WERE SENDING TO A DECEASED PERSON TO WRONG ADDRESS. BUT SINCE IT IS EXPIRED, THERE IS NOTHING I CAN DO FOR A FAULTY FUEL TANK THAT IS EXTREMELY DANGEROUS

20200330FUEL/PROPULSION SYSTEM
2004 MERCEDES E320 HAS A STRONG GAS SMELL. TOOK VEHICLE TO DEALER AND FOUND OUT THAT "1/3 THE FUEL TANK HAS A COVER ON TOP OF IT-SANDWICHED BETWEEN THE TOP OF THE TANK AND THE FLOOR OF THE VEHICLE THE TANK IS LEAKING WHERE THE COVER MEETS THE 2/3 TANK WHEN YOU PULL THE BACK SEAT OUT YOU CAN SEE THE TANK TOP-FUEL IS SEEPING OUT STAINING THE SIDE OF THE TANK" I WAS TOLD THERE WAS A 15 YEAR EXTENDED WARRANTY DUE TO THIS ISSUE AND I WAS ADVISED IT EXPIRED. I WAS NEVER NOTIFIED OF THE EXTENDED WARRANTY AND I HAVE OWNED THE CAR FOR 12 YEARS. I REACHED OUT THE MERCEDES HEADQUARTERS AND THEY ADVISE ITS NOTHING THEY COULD DO. THIS IS A BIG SAFETY ISSUE BECAUSE THE CAR CAN CATCH ON FIRE. SHOULDN'T THIS HAVE BEEN A RECALL? DOES SOMEONE HAVE TO DIE BEFORE IT IS. MERCEDES STILL STATED NOTHING THEY COULD DO. THE TANK WILL COST $2300 AND THEY ADVISE NO AFTERMARKET AVAILABLE. THIS IS UNFAIR TO THE CONSUMER BY ALL MEANS. MERCEDES KNOWING KNEW THERE WAS A ISSUE AND NO RECALL HAS BEEN DONE
