Check fuel fill inlet. 2013 Ford Mustang?

I'm 18, I saved up all my money from work and I just bought a 2013 mustang in cash less then a week ago from a dealership. I bought the gold premium warrenty for 48 months. A message came up that said "check fuel fill inlet" a few days ago. Not positive on what it means, or the severity of it. Some insight would be great.

Gas cap buddy

This car has Ford's "Easy Fuel" capless fuel filler inlet. The inlet may have an obstruction stuck in it or the check ball may be stuck. If you have the warranty, I'd take it in. This may be considered an emissions equipment issue, which should be covered under a federally mandated warranty anyway.

Check the gas cap. You may not have gotten it on tightly.

Gas cap, pop her off and back on good… Or it thinks gas cap (vacuum leak losing gas tank pressure)

Really? You know the cap you take off to gas up. I can't imagine they built it into the door that pops open, if so then that

dang thank you fodaddy

"it would appear that sticking Easy-Fills aren't that uncommon, with the cure usually being a vigorous hammering at the dealership."

There's a pollution system that sucks the gasoline vapors out of the gas tank when the car is just sitting, to keep them from escaping to the athmosphere. That system requires that the gas cap completely seal the fuel tank, even to a vaccuum. If the gas cap is either loose or leaking, it will give you that error code.

Ford Mustangs are cool
