Possible Causes

Overheating of internal components causing silent derating, Loose supply terminals causing voltage drop, Marginal contact in Type 2 connector, Weak Wi-Fi or load management commands stopping charge

How to Fix / Troubleshooting

Safety first: Repeated interruptions can indicate overheating or wiring issues. Do not ignore burning smells or hot surfaces.

  • 1. Check for heat: After a stopped session, gently touch the charger housing and cable. Warm is normal; very hot or soft plastic is not. If excessively hot, stop using and call a technician.
  • 2. Disable smart features temporarily: In the Kia app, disable scheduled charging, load management, or remote stop features and test a manual session.
  • 3. Inspect supply wiring (electrician): Have an electrician tighten all terminals and verify that voltage remains stable during charging.
  • 4. Inspect connector fit: Ensure the plug seats fully in the vehicle inlet with no wobble. A worn connector may need replacement.
