• Check the gas cap first — a loose or damaged cap is a common trigger and an easy fix.

• Look for other dashboard alerts (battery, hybrid system, or ABS) that help prioritize repairs.
• If the 2020 Toyota Prius Prime is plugged in, ensure it is charging normally and the EV system shows no faults.
