2. Ensure the port is dry and free from liquid before attempting to charge again.

4. Test Charging Station

Sub-steps:
1. Attempt to charge the vehicle using a different charging station or outlet.
2. If charging works at another station, the original station may be faulty.

5. Update Software

Sub-steps:
1. Connect the vehicle to Wi-Fi.
2. Navigate to 'Software' in the settings and check for updates.
3. Install any available updates to ensure optimal charging functionality.

6. Check Vehicle's Electrical System
