Gas cap access door/ closing magnet mechanism

Sounds like you also might have also bent the hinge and or door itself. Without pictures we can only guess. An auto body shop, dealer service department or mechanic might be able to help.

My Dad did the same thing, would up needing to replace the actuator assembly and the a new gas door that required repainting to match the truck. He didn’t say how much it cost but he did say next time he will just hot water and blow it dry after it opens.

Since the vehicle is only a year old take it back to the Dealer! Depending on what needs to be fixed maybe they'll work with you and get it done under warranty. It doesn't hurt to ask. Hope that helps! Jim

Junkyard part. Don't buy new and get both the door and the magnet or switch mechanism Dealer cost will be high..
