Some drivers worry that this exposes their gas tank to thieves and/or saboteurs, but this feature only works while the car is unlocked. If you try to open your gas tank this way without first unlocking your vehicle, it will remain closed and locked just like your regular car doors.
If you unlock your car and press on the fuel tank door to no avail, there may be an issue with the locking mechanism on your door. In these cases, it’s best to check with your mechanic to make sure that your vehicle isn’t experiencing electrical issues.
