What the Loose Gas Cap Light Means on a Mitsubishi Outlander PHEV
The loose gas cap light on a Mitsubishi Outlander PHEV warns that the fuel filler cap is not sealed, which lets the evaporative emissions (EVAP) system detect a leak. It is a cheap, easy fix but can otherwise trigger the check engine light.

It depends on the urgency (low) and how your Mitsubishi Outlander PHEV is behaving. If the light is red or flashing, or the car drives differently, stop safely and get help. If it is amber and everything feels normal, you can usually drive to a workshop soon — just do not put off the diagnosis.
How much does it cost to fix the Loose Gas Cap Light on a Mitsubishi Outlander PHEV?
