Hi there, I am fairly new to Maya and I've been this issue for a bit. For some weird reason the symmetry on my object just doesn't work, it works if I put it in world but not in object which is odd. Anyone know a way to fix this issue?

Symmetry feature seems to be pivot-centric by default, e.g. it won't budge once you skin your model and offset in space. However, it comes with additional Topology option:
Once you opt for it, Maya invokes in SelectSymmetryEdge mode, where you can click on any edge that represents symmetry.. after that it should work again + you can adjust the Tolerance option, which is two edged sword, as it also might select neighboring elements.
Sorry, I didn't check your file, I believe the model is ok.
trying the topology option states that the mesh isn´t symmetrical which seems not to be true by my definition but you have created non-manifold/invalid geometry at the mouth exactly at the center which the topo feature doesnt like. (there is more so make sure you check your mesh using "mesh > cleanup")
object symmetry will work non the less but as @hamsterHamster said it very picky on the pivot and transforms. so in your case "modify > bake pivot" will make it work.
