Imported Model importing with random black faces

Hello,

Im trying to import some car files into a project I’m working on however the model keeps coming in with messed up geometry. When they open if Rhino or Maya they look clean. I have attached two screen shots. One from Maya and one from Unreal to show the issue. It doesnt seem top be the file format, It is happening with both fbx and obj in the same way. If anyone has an idea of what might be happening please let me know.

Thank you!
