So Im making a racing game in Unity, but im having a problem, Whenever i add a car controller and hit play, my wheel flip flat, and pivot on that axis. I have tried editing the pivot point in Blender, but no luck. Im also getting this error, not sure if it is related but ill include it anyways. Also, im using the car controller that comes with unity. 
So I ended up solving the problem by using a different wheel model, it must of been the pivot point on the other model.
