Hey friends, my gas cap seems to be trapping air in the tank at the moment. Whenever I go to fill up, it starts and stops and every time it stops I hear the air whistle out. This hasn't caused any driving issues but it has made filling the tank obnoxious in the winter. My first thought and the mechanics first thought was that the purge valve needs to be replaced, however I noticed it doesn't have any issues whatsoever when the car is on, even in just electric mode (car not fully on). Could this be a software bug that needs to be fixed? How could it be the purge valve if it only happens when the car is off?
Additionally, the button to release the cap hasn't been working, I've been using the manual release in the trunk. My guess is the actuator needs to be replaced. Could that be related to the issue? Thanks to anyone who can offer some help!
