Solution

1. Preparation

Gather necessary tools: a clean cloth, flashlight, and possibly a flathead screwdriver for prying.
Ensure the vehicle is parked safely and powered off.

2. Inspect and Clean the Charging Port

Use the clean cloth to wipe the charging port area to remove any debris or dirt that may be obstructing the port.
Check the alignment of the charging port door; ensure it is not misaligned or jammed.

3. Manually Open the Charging Port

If the charging port does not respond, gently insert a flathead screwdriver into the small slot located near the charging port.
Carefully pry open the charging port door to see if it will move freely.

4. Electrical Connection Check

Open the trunk and locate the wiring harness connected to the charging port assembly.
Ensure that all connectors are secure and that there are no signs of corrosion or damage.
If necessary, disconnect and reconnect the wiring harness to refresh the connection.

5. Software Reset

With the vehicle in park, perform a soft reset by holding down both scroll wheels on the steering wheel until the touchscreen turns off and then back on.
After the reset, attempt to open the charging port again using the vehicle's button or mobile app.

6. Replace Charging Port Assembly (if needed)

If the charging port still does not open, it may be necessary to replace the charging port assembly.
Remove the interior panels surrounding the charging port following manufacturer guidelines.
Disconnect the old charging port assembly and replace it with a new unit, securing all connectors properly.
