I have had my Tesla for almost 2 years. Starting last month I started having problems with the car not allowing the plug to be inserted even though the car is on, door open and I have the key in my hand. Eventually it does work either by opening another door or using the display. Other times, it inserts correctly but there is no light... so it does not charge. Last, sometimes it charges but the only way to release it when complete is via the display. I took it to Devon Tesla last week and they reported that nothing was wrong. Any idea what could cause this? They also mentioned that via the microphone I can create a timestamp to help them diagnose the issue. Can anyone explain how to do this since what I have tried has not work. I also installed new key fob batteries but this may no difference. thanks
