Possible Causes

Undersized supply wiring, Loose terminal screws at input or contactor, Worn or oxidized contacts in charge handle, Continuous operation at maximum current in high ambient temperature

How to Fix / Troubleshooting

Safety first: If you smell burning plastic or see smoke, shut off power immediately at the breaker.

  • Step 1 – Reduce current: In the Rivian app, lower the maximum charging current and monitor temperature over a session.
  • Step 2 – Check handle temperature: If only the handle is hot, inspect the connector pins for discoloration or pitting. Replace the handle/cable assembly if damage is visible.
  • Step 3 – Inspect internal lugs: With power OFF and cover removed, check and retorque the input and output lugs to manufacturer specs.
  • Step 4 – Evaluate environment: Improve ventilation around the charger and avoid charging during peak heat if possible.

Persistent overheating indicates a need for professional evaluation and likely replacement of the cable or internal contactor.
