2020 NitroZ21 cockpit deck cracking

[NitroZ9999]

Looking for anyone that has a soft spot in their Nitro Z20 or Z21. My son was stepping down off the front deck into the cockpit this past Spring & it made a terrible cracking sound now the floor sinks down about an inch or more everytime we step in the center of the cockpit…..? When you tap the floor in this area it sounds hollow? Is this a broke stringer issue?
Major structural issue either way…called WRMG & tgey said it wasn’t covered under warranty….

Are you the original owner? Thought these things had a life time warranty for structural issues the the original owner.
