A non-manifold error is showing up whenever I try and use 2 symmetry planes to generate an enclosure around my car saying it cannot because of non-manifold bodies. I don't understand what I should do to resolve it, can someone tell me what it is I should do?

Here's the geometry of the file and relevant screenshots:

I use the STEP file for Ansys Workbench 18.2. Please suggest what it is that I should do!
My symetry planes are ZX plane and YX plane, but it throws up the error when I mention the ZX plane! And are there any other errors in the geometry that can affect the simulations later?

I had the same problem before and the solution is to flatten the tire and create an extrusion underneath the wheels. It makes sense to do this since in real life your tire will flatten a bit on the ground making a plane as a result.

when you create the cut make sure to have some sort of extrusion underneath so you can avoid having a "cusp" around the wheels. It will make your life easier later on.

hope this helps

Thank you so much! It works!

I have a new problem, the enclosure after Boolean subtraction creates two square holes at the bottom where the tires are flattened and although meshing is successful, I'm unable to close them up by meshing and an stairstep warning is also showing up. How do I fix it? Suggestions mentioned increase maximum angle to 180 degrees but it didn't work. Images in link!
