The hinges may be wore out. Where applicable, you can take hinge bolts loose and see if there is any adjustment. Also, check the catch, see if adjustable.

I realize this is an old post. In the future hope you don't have any vehicle issues, but, if you do, keep the site in mind. They are always working to improve the site and it's free to ask a question.

Have a good day.
