Symptoms
- Charging fault icon or message when plugged in
- Charging stops, doesn't start, or is much slower than expected
- May happen with one specific charger/cable but not others
Likely causes
- CommonFaulty or damaged charging cableCables can develop internal wear, especially with frequent use or outdoor storage.
- CommonDirty or damaged charging port on the carDebris or bent pins can prevent a good connection.
- CommonProblem with the charging station itselfPublic and home chargers can have their own faults unrelated to the car.
- PossibleOnboard charger module faultThe car's internal hardware that manages AC charging can fail.
- Less commonExtreme temperature limiting charge rateVery hot or cold weather can slow charging as a protective measure.
What to do
- Try a different charger or charging station if one is available, to isolate whether it's the car or the charger.
- Inspect the charging port on the car for debris, moisture, or bent pins.
- Check the charging cable for visible damage, especially near the connectors.
- Unplug and firmly reconnect the cable, making sure it clicks/locks in place.
- Restart the car (or the app, if using a smart charger) and try again.
- If it fails on multiple chargers and cables, have the car's charging system diagnosed by a dealer.
- Contact the charging network's support line if the fault seems to be with a public charging station.
When to call a pro
See an EV-certified dealer or specialist if the fault persists across multiple chargers and cables, which points to an onboard charging system issue.
