My new Model 3 LR arrived last weekend. I had a Wall charger installed in my garage a while back. The first time I went to charge the car I pressed the button on the Wall charger handle to open the Charging port door and nothing happened. I had to open it by hand. I've been using the app now to open and unlock the charger, that works fine. I had a service call yesterday at my home. The Tesla service man concluded there's something wrong with the Wall charger. They gave me a phone number to call specifically for the charger and said they would repair or replace it. So I called and spoke to someone who had a real attitude and said "if the charger is charging your car then the problem is the car not the charger" and she instructed me to schdelu another service appointment, which I did. She said I need to try another charger somewhere else to see if that makes a difference. What's so frustrating is that Tesla Cars & Tesla Chargers are 2 different divisions of the same company that don't seem to want to work together. I'll bring my car to a service center and try their charger, if the charging door opens then the problem is my Wall charger. Anybody have similar experience dealing with this problem and how it got resolved?
