Smell of Gas inside my car ... mechanic says there is no visible fuel leak?

[durome]

I bought new Dodge Grand Caravan (2015). Van has a gasoline odor. Dealer check it for leaks and found none. So dealer had van detail. Odor was still there. So I left van at dealer. The next day I returned to the dealer and this time they had sprayed the interior with something that only masked the odor. What should I do?

Spraying to cover a GAS odor is NOT going to solve the problem. Gas is GAS and a possible FIRE in the making.

I would ask for another car or a REFUND.

As a former mechanic and business owner (now retired) have seen too many cars in the past with FIRE damage from a GAS leak problem.

I hade the same problem.. Yesterday I went to my Dominican mechanic who has 35 years of experience. He did smoke pressure test no leaks were detected although the engine light indicated that I had a massive rear leakage. My Mechanic diagnosed the problem to be fule "valve" that has an electric switch that is supposed to close and open. He removed the switch tested it with voltmeter it was not working. After working on the switch "Valve"for a few minutes it started working we put it back in and I am now driving the car to see if the engine light and gas smell returns. I am hoping this was the problem. My car is a 2002 Nissan Sentra 1.8 engine
