Possible Causes

Deformed plastic housing on GM J1772 handle, Slightly bent alignment key, Swollen or melted areas from overheating, Debris lodged in connector or vehicle port

How to Fix / Troubleshooting

Safety first: Do not force the connector; forcing can damage the vehicle’s charge port.

Steps:

  • Inspect visually: With power OFF, compare the GM connector to images in the manual. Look for warping, cracks, or melted areas.
  • Clean gently: Remove any visible debris from the connector and vehicle port with a dry, soft brush.
  • Check latch operation: Ensure the latch moves freely and is not catching on the vehicle port.

If insertion/removal remains difficult, the connector body may be deformed from heat or impact. The safe remedy is replacement of the GM J1772 cable and handle assembly.
