Use a soft cloth to clean the charging port and connector to remove any debris.
Inspect the charging cable for any visible damage or fraying.
Ensure the connector is securely plugged into the vehicle.

4. Reset Driving Mode

Access the vehicle settings on the touchscreen.
Navigate to the "Driving" section and select the "Acceleration" option.
Change the setting to "Ludicrous" or "Plaid" mode, if available, to enhance acceleration performance.
