2013 NISSAN MAXIMA Fuelpropulsion System Problems

I PURCHASED THE VEHICLE IN 2017 WITH 39997 MILES ON IT. WHEN I TOOK IT TO THE GAS STATION THE PUMP SHUT OFF EVERY 6 CENTS. THE PLACE I PURCHASED THE VEHICLE AT WOULDN'T DO ANYTHING BECAUSE THE CAR WAS SOLD "AS IS' AND A WEEK HAD PASSED. I DIDN'T TAKE THE CAR IN FOR REPAIRS BECAUSE I DIDN'T HAVE THE MONEY . I REFINANCED THE VEHICLE IN 2018. SHORTLY AFTER THAT I RECEIVED I LETTER IN THE MAIL FROM NISSAN OF A WARRANTY POLICY ENHANCEMENT WHICH WAS FOR COMPLETE EVAP TUBE BLOCKAGE. READING FURTHER THE LETTER DESCRIBED EXACTLY WHAT MY CAR WAS DOING. SO I TAKE THE CAR TO PISCHKE MOTORS NISSAN FOR REPAIRS. THE CAR HAD 69978 MILES ON IT AT THAT TIME. THEY TOLD ME THAT IT HAD TO BE A COMPLETE EVAP TUBE BLOCKAGE TO BE COVERED BY THE WARRANTY. I WAS THINKING THAT THATS WHAT...
