Step-by-Step Fix Instructions

  1. 1

    Inspect your charging plug pin slots to check for collapsed, pushed-back, or heavily corroded interior pins.

  2. 2

    Swap over to a separate charging cable or public station hookup post to rule out an external hardware issue.

  3. 3

    Clean out the internal charge socket pins using quick-drying electronic contact cleaner spray fluid.

  4. 4

    Check the vehicle's low-voltage accessory battery condition; a weak 12V battery can drop charging logic bus rails.

  5. 5

    Access the internal charge controller module inside the trunk trim layer to check for tight harness connections.

  6. 6

    Replace the internal charge port locking assembly pin mechanism or install a new charging interface socket.
