In the past few months I have noticed that that when I push the button to release the charging cable it turns white, I hear a noise but it doesn't release. I either have to repeatedly push the button or hold it down for 10s or so to get it to release. Same thing happens if I try to release using the button by the charge port on the car. I wasn't sure if it was the cable or my car, but this morning I quickly stopped at a supercharger and it did the same thing, so it's likely the car. Has anybody had their charge port go bad and have to be replaced. I'm worried I'll end up stuck somewhere so will probably make an appointment to get it fixed.
