Charge port makes 4 clicks when opening before pin retracts...

Every time I open the port to charge, it clicks 4 times before the pin on the bottom retracts and I get the white ring. So I can charge fine but I don't remember hearing this before. It's always exactly 4 clicks. If it was some sort of sticking issue, you'd think the number of clicks would vary.

I have a brand new sealed charge port I bought a few years ago just in case I ever get stranded because of a failed port but not ready to install it quite yet if it turns out this is not a real issue.

I'm still on V8.1..at least until next week when I do the MCU2 upgrade.

Update on Dec. 6, 2018 Posting: My current firmware is 2018.49.12.1. I had mobile service twice since posting on Dec. 6, 2018. They took care of all problems (minor) except for the clicking on the charging port. The service tech explained that the clicking is related to a "cold weather feature". He explained that the charge port has a solenoid which turns on and off creating the ticking sound. This is designed to make sure that the charge port does not freeze . According to the tech, the ticking is enabled by the computer right around 8C (46F). It has been below 8C for the entire month and I have no way to confirm what he says until it gets warmer. I will post an update if I learn anything more or when the weather gets warmer.

What was the final resolution on this issue?
Mine started doing this a few weeks ago, shortly before I received an error for the charge port door sensor. Now the door doesn’t work right, always thinks it’s open even when it’s not. Have a service appointment next week to get it looked at.

Do you park outside by chance? Apparently this is a somewhat common problem because water intrudes into the charge port door and pools around the sensor/electronics. Thinking all the rain we had in December made mine fail.

Charge port door. There's a sensor in the door that detects when it is open and it progressively failed until would no longer charge. I did not get a door sensor error so I thought it was the charge port. So I installed a new port, installed the staged next version of software which did not fix the issue.

I then replaced the door ($85) which fixed the issue and it's been fine ever since.

Mine has always been garaged.
