I've been finding high values for RSD when determining precision in our HS-GC. I prepped a 0.5% solution of ethanol.

Have you tried stabilizing the headspace by adding a tiny amount of NaCl ?

Welcome to the forum.
You are new here, your first lesson is that sensible answers require actual questions, and nobody can troubleshoot without details of what you are doing and how.

Did you add a tiny amount of NaCl? Have you finished the chemical analysis?
