ISSUE UV map baking not following the mesh

Hello guys, I’m working on this cartoon police car and I really need a quick fix, I bet you guys can help me in a blink of an eye. Wierd simple issue i’m facing, the uv map thing when i bake it doesn’t repext my mesh and is going a bit too thick, and i need it for tomorrow (last minute job bad on me). Any ideas? Thanks a lot!
