Button wouldn't pop gas cap. If someone pushed the button you could then pry it from the outside - 2 person job. When I had the dealer look at it, they quoted a part and labor in the neighborhood of $300 for a fix. They'd seen the issue before on other Dodges. It is currently working again, however the cap is very loose.

this is a manufacture problem, I have seen multiple complaints and dangerous at times when getting out to open on highway for gas.
