Solution

1. Preparation

Tools Required: Tesla app for diagnostics, laptop with internet access for software updates.
Ensure the vehicle is in an open area with adequate lighting for inspection.

2. Update Software

Connect the vehicle to Wi-Fi.
Navigate to "Software" in the settings menu.
Check for available updates and install them.
Restart the vehicle if necessary after the update completes.

3. Adjust Settings

Open the Tesla app and navigate to "Controls."
Disable features that may lead to battery drain:
- Turn off "Sentry Mode" if not needed.
- Disable "Always Connected" if the feature is not essential.
Confirm that "Walk Away Door Lock" is functioning properly and adjust settings if needed.

4. Inspect and Close Components

Physically inspect all doors, trunk, and hood to ensure they are securely closed.
If any components are not closing properly, realign or repair as necessary.

5. Monitor Power Consumption

After making the adjustments, park the vehicle for a set period (e.g., 24 hours).
Use the Tesla app to monitor the battery drain during this time.
If the drain persists at an abnormal rate, consider contacting Tesla service for further diagnostics.
