Why do I smell horrible gas fumes from my 2017 Ford Edge in my garage??

What is your question?

Bought a new left over 2017 Ford Edge. It has just flipped 1000 miles. After short trips of 25 miles or less, I put this vehicle in my garage. I smell gas fumes for several days. One would think I'd spilled some gas but that is not the case. There are no leaks. These gas fumes are strong enough that they actually seep into my attached breezeway. I'm very concerned that some part of this vehicle isn't functioning correctly. Also fear for some kind of explosion! Can you help?

What makes this problem better or worse?

It's worse after a trip

How long has your 2017 Ford Edge had this problem?

several weeks
