High-voltage plug disconnection and port locking security on the 2023 Mercedes S-Class plug-in hybrid or electric models are regulated by electronic charging port locks, vehicle central unlocking signals, and connector release latches.
How to Fix It:
-
Unlock the Vehicle: Ensure the vehicle doors are fully unlocked using the key fob or interior unlock switch to release the charging port lock pin.
-
Check Indicator Light: Look at the status light near the charging socket to confirm it turns white or blue, indicating the locking pin has retracted.
-
Press Release and Pull: Press the release button on the cable handle and pull the connector straight out of the socket without applying bending force.
