    I've been charging my 2017 Prius Prime Advanced at work for almost a year on ChargePoint chargers, with no problems at all. Today, I went out to unplug when my car finished charging, and I couldn't get the charge cable to disconnect from the car. I had my key with me, and I could clearly see the locking mechanism moving in and out when I pressed the charge cable lock button. I went in circles with ChargePoint, the local Toyota dealer who services my car and Toyota Roadside Assistance. I finally had to give up and have my wife come pick me up at work. I'm headed back to the dealer tomorrow, who said they would be more helpful when they had both mechanics and managers available. In the meantime, has anyone had this problem? I didn't see anything in this forum, other than one person who didn't have his/her key on their person. I'll post an update when I get the problem fixed... I can't believe how many people suggested that I have the car towed to the dealership :)

    Is it the same ChargePoint charger cable you have been using in the past? Have you always used the connector locking system by pushing the small button inside of the charge port? (red arrow in the diagram) Did the SKS work with your key for the other doors (2 front doors and 1 hatch? I guess it is possible that the antenna for the charge port is specifically damaged. Maybe battery in the fob is weak???
    IDK. I hope you can solve this mystery quickly, but whatever you find out, please let us know the solution.

    Since the lock mechanism is responding to you manually pressing the switch, this may not help, but have you tried this emergency procedure?

    Thanks - yes, I did try the emergency procedure as well. I was glad to learn about that procedure, even though it didn't help this time. This morning a local Toyota mechanic came out, and after verifying that there were no other locks in the system, he muscled out the charge connector. One of the charger pins appeared to have fused into the socket, and remained behind in my Prius. My Toyota dealer now has the car and they are investigating what went wrong. When they let me know what happened, I will update this post for future reference.

    Wow!, You must be glad it did not cause a fire or something. I wonder if it was the car or Charge Point charger that caused this. Obviously, the charger cord must be out of use as well. Is Charge Point doing any investigation?

    Interesting. I had an extension cord fuse to the receptacle on my leaf blower a few years ago. Sounds like the same type of situation.

    WOW!!
    From that second picture showing the Charge Port part stuck in your charging port, it looks like the Charge Port pin was severely corroded.

    Finally received word from ChargePoint - they have no idea what caused the problem, and didn't see anything wrong with their system or the charging connector. Toyota (a long time ago now) also found nothing in the car that might have caused the problem. So, unfortunately, I have no idea what caused the problem in the first place.

    Thanks for the update. Was repair covered by warranty or did you have to pay out of your pocket?

    Out of pocket, as neither Toyota or ChargePoint believe their side to be at fault. So I guess I must have plugged it in wrong o_O Fortunately, our insurance will cover the repair cost.

    Was that your comprehensive that paid for the repair on the car? Did you (or your insurance) have to pay to repair the ChargePoint EVSE too?

    Corrosion in the ChargePoint J1772 increasing the diameter of the terminal? That might explain it getting stuck in there.

    Yes, since no one knows what caused it, we have a blame vacuum. Which has sucked me up into it. Oh well, there are worse problems in life...

    That makes a lot of sense. I am going to pay attention to the charge contacts when I plug in, and see if I ever notice anything unusual. Thanks!

    My comprehensive covered the cost of the Prius repair. I'm not sure if ChargePoint or my company paid for the repairs to the charger - that had never occurred to me! I'm glad it didn't come up.
