Symptoms
- Car or charger screen shows a numbered or named error code
- Charging stops or won't start with the code displayed
- Error may clear on its own after retrying
- Error is consistent across multiple charging attempts
Likely causes
- CommonLoose or poor connector contactMany charging errors are simply the system detecting an unreliable electrical connection.
- CommonCharger-side fault rather than car faultSome error codes originate from the charging station itself, especially at public chargers.
- PossibleExtreme battery temperatureVery hot or cold battery temperatures can trigger a protective error that clears once temperature normalizes.
- PossibleOnboard charger faultA hardware issue in the car's own charging equipment can produce a persistent error code.
What to do
- Write down the exact error code or message shown, since this is the most useful piece of information for diagnosis.
- Unplug and firmly reconnect the charging cable, checking that it's fully seated and locked.
- Try a different charger or outlet if available to see if the error is charger-specific.
- If the error mentions temperature, let the car sit for a while to reach a more moderate temperature before retrying.
- Search the exact error code in your owner's manual or the manufacturer's support site, since many have specific documented meanings.
- If the same error persists across different chargers and conditions, contact the manufacturer or a dealer with the exact code.
When to call a pro
If the error persists across multiple chargers and conditions, a dealer can look up the exact code and diagnose the onboard charging system.
