Gas tank "burp"

Mine did the same thing for years. I learned just to not fill it up all the way. Finally the did a recall. Take it to your local dealership and they will replace your tank for free ($1100. value).

Take it to an independent Chrysler specialist. It should be easy to diagnose and fix. Here's a directory link for you: https://repairpal.com/chrysler-repair-in-south-mills-north-carolina
