Solution

1. Software Verification

Ensure the vehicle is running the latest software version. Navigate to "Software" in the settings and check for any pending updates.
If issues persist post-update, consider rolling back to a previous version if available.

2. Reset Energy Settings

Go to "Settings" > "Energy" and reset the energy settings to default. This can recalibrate the battery management system.

3. Battery Calibration

Fully charge the battery to 100% and then drive until the battery is nearly depleted (around 10%).
Recharge to 100% again without interruption to recalibrate the battery management system.

4. Tire Maintenance

Check and adjust tire pressure to the manufacturer-recommended levels (typically around 42 PSI for Model 3).
Inspect tires for excessive wear or damage and replace if necessary.

5. Feature Management

Disable unnecessary features that may drain energy, such as "Sentry Mode" or "Always Connected" if not needed.

6. Contact Tesla Support

If reduced range persists after performing the above steps, contact Tesla support for further diagnostics and potential service evaluation.
