2009 Cadillac DTS Fuel System Problems

HAVE BEEN SMELLING GAS AFTER FILL UPS FOR SEVERAL MONTHS. EACH TIME I FILL IT AND PARK IT IN MY GARAGE IT FILLS WITH GAS FUMES THAT COULD EXPLODE AND KILL SOMEONE UNAWARE. ODOR LEAVES AFTER DRIVING 30 MILES OR SO. GOT CHECK ENGINE LIGHT AND O'REILY AUTO PARTS CHECK AND SAID IT SHOWED FUEL ISSUES. TOOK CAR TO MY GM DEALER AND THEY SAY NEED A NEW GAS TANK, A NEW GAS CAP AND NEW EVAPORATIVE LINES BECAUSE I HAVE A LEAKING GAS TANK LEAKING AT OR NEAR FILLING AREA, AND GAS CAP IS NOT GOOD AND LINES ARE LEAKING ACCORDING TO A "SMOKE" TEST. REPAIRS ARE $2,800. I AM 75 YRS OLD AND HAVE NEVER HAD A GAS TANK LEAK AT THE "NECK" AREA AFTER OWNING SOME 40 DIFFERENT CARS, SOME OF THEM VERY OLD. I BELIEVE THIS MAY BE A FACTORY DEFECTIVE PRODUCT AND A DANGEROUS ONE AT THAT. IT IS CURRENTLY AT THE DEALER AND TOMORROW I WILL PAY $175 FOR THE SMOKE TEST BUT I CANNOT AFFORD TO FIX IT SO I WILL ONLY FILL IT TO THE 12 GALLON POINT INSTEAD OF FULL. PLEASE ADVISE IF THERE IS A RECALL OR PERHAPS OTHER CADILLAC DTS OWNERS WITH THIS OR A SIMILAR PROBLEM

FUEL RELAY MELTED I REPLACED IT AND MELTED AGAIN JUST LIKE MY OTHER CADILLAC DTS. BOTH ARE SAME YEAR AND ALSO SAME MILES. I GET THAT FIXED BY DEALER ON 03/26/2013 AND THIS ONE AT DEALER SINCE LAST MONDAY. PROBLEM RELAY BOXES IS GOING TO BE REPLACED JUST LIKE THE OTHER ONE. MELTING IS VERY DANGEROUS WHEN RELAY BOX RIGHT UNDER THE BACK SEATS. *TR

FUEL RELAY KEEP BURNING MELTING DUE TO OVERHEAT. RELAY BOC IS UNDER THE BACK SEAT I DON'T THINK THAT SHOULD BE SAFE AND HAS TO BE RECALLED ALL DTS I HAVE THIS ONE HAPPENED OVER TWO MONTHS AGO THIS CAR WAS 93325K AT THAT TIME. MY OTHER 09 CADILLAC DTS HAS SAME PROBLEM AND IN DEALER SERVICE RIGHT NOW AND THAT CAR HAS 94200 K ON IT. BOTH 2009 DTS IS IT JUST A COINCIDENCE. *TR
