Hey, I may have a solution for you, based on the opposite problem I just had yesterday with our car. When I hooked up the cable to our car, after a long trip, it started making ugly 'clicking' noises I've never heard before. Didn't think there was a problem until I saw a red triangle on the dash, which said the cable didn't latch, and wasn't charging. So I removed it, and this time consciously shoved it in there solidly, to make sure it was all the way in. No problem after that. So my suggestion for you is to also shove the cable in before pressing on the button, which might reduce the force required on the motor to unlatch it. Give it a try, and see if that works .There is a clicking sound, but the cable remains stuck until I release it from the trunk.
I honestly tried everything for the same type of problem, and this was the only thing that worked surprisingly. Just tapped it with my palm lightly a few times while using the cable’s wireless unlock button simultaneously. Don’t know if this fix will necessarily work for everyone, but definitely worth a try if you’re in a tough predicament with a need for immediate charging. Shout out to Sophias dad for the advice!Strangely, I had this happen to me this morning(first time). I eventually opened it with a couple gentle whacks on the charge port door.
The lid isn't actually ever locked down, if you can't get it open electrically just lift the lid with a fingernail, credit card, suction cup...predicament with a need for immediate charging
