Has injector wires shorting out against tunnel wall been much of a problem on 2018 MC or just occasionally? What's the fix?

There is a technical service bulletin on that. I never had mine done, but I did rotate the injectors slightly to get the plugs away from the tunnel. I also globbed some RTV on the harness at the wire to plug interface to try to prevent the wires from breaking over time. Thoughtful zip tie use can help keep things in place too.

Make sure if you disconnect the injectors you get the wire lock fully seated. Previous owner [or someone else] failed to do that on my '18. The harness wire socket and injector pin wore eachother out to the point both were trashed. New injector and new harness, fixed.

Worn injector pins.
