Symptoms
- Charging starts but stops before completing multiple times
- App or charger shows the session ended unexpectedly
- Problem happens at the same charger or different chargers
- Sometimes resumes on its own, sometimes needs manual restart
Likely causes
- CommonLoose or poor cable connectionA connector that isn't fully seated can intermittently lose contact, especially if bumped.
- CommonCharging network connectivity issuesPublic chargers depend on a stable internet connection, and network drops can end sessions unexpectedly.
- PossibleCar's charge limit or schedule ending the sessionA set limit or schedule can cause the car to intentionally stop charging, which can look like an interruption.
- PossibleCharger hardware faultAn aging or malfunctioning charging station can drop sessions inconsistently.
What to do
- Check that the cable is fully seated and locked at both the car and the charger.
- Review your car's charge limit and schedule settings to rule out an intentional stop.
- If using a public charger, check the network's app or website for reported outages at that location.
- Try a different charger or charging network to see if the interruptions are location-specific.
- Keep a record of when interruptions happen (time, location, charger type) to help identify a pattern.
- If interruptions happen consistently at home, have the home charger and its circuit inspected.
When to call a pro
If interruptions happen across multiple chargers and locations, have a dealer check the car's onboard charging system.
