NHTSA Complaint #11043291 — 2014 CHEVROLET CORVETTE

I NOTICED YESTERDAY WHEN ENTERING MY POLE BARN, A STRONG FUEL ODOR..UPON EXTENSIVE SMELLING, I LOCATED A FUEL LEAK WHEN I HAD THE CAR ON MY LIFT, THE FUEL TANK ON THE DRIVERS SIDE HAS GASOLINE RUNNING DOWN THE PLASTIC TANK. I HAVE MODINE HEATERS IN THIS BLDG, SO I LOWERED THE CAR AND PUSHED IT OUTSIDE WITH HELP. I BOUGHT THE CAR PRE OWNED FROM BERSTROM CHEVY IN OSHKOSH, AND THEY NEVER GAVE ME SOME LETTER THAT I LEARNED WAS SENT TO ALL OWNERS ABOUT THIS PROBLEM, JUST SHORT OF A RECALL. GM EXTENDED THE WARRANTY TO 6 YEARS FOR THIS PROBLEM IF YOU GET IT.. I WANT TO KNOW WHAT IS THE CAUSE OF THIS, BECAUSE IF THEY JUST REPLACE THE NEEDED PARTS, HOW DO I KNOW THIS WILL NOT RE OCCUR.. I READ MANY C7 VETTS FROM 2014 - 2017 HAVE THIS PROBLEM. WHAT SHOULD I DO?
