took it back this morning pissed off and said enough is enough. so now they are trying this out. they filled up the tank with gas at there expense then after putting back on the second new gas cap GOT SOME BLACK DUCT TAPE AND TAPED THE CAP INTO PLACE SO IT WOULDN'T MOVE I GUESS. They told me to drive the car until it got down to 1/4 tank and bring it back.They would do this test twice and if the light stays off they would then order another new gas cap.

If light comes on before then they said they would have to call in a another nissan factory tech. sorry to ramble but needed to vent.
