My 2020 premier is in the garage fully charged but I cannot get the level 2 charger unplugged from the port. The latch on the charger plug works fine but something is catching and holding the plug when trying to unplug it. I have locked/unlocked the doors many times with both fobs, disconnected the 12v battery twice, and even banged on the fender around the port per suggestion. Nothing seems to help releasing the plug from the car. Any suggestions as cannot leave the garage with the cord attached!!
