Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Ensure the vehicle is in "Park" mode and the ignition is off.

2. Battery Health Check

Access the vehicle's settings menu.
Navigate to the "Battery" section and check the health percentage.
If the battery health is significantly low (below 80%), consider contacting Tesla service for possible replacement.

3. Update Software

Connect the vehicle to Wi-Fi.
Check for any available software updates in the settings.
Follow the prompts to install any updates, which may contain fixes for battery management.

4. Inspect Energy Consumption

Monitor the energy consumption via the dashboard during a drive.
Validate if the consumption aligns with normal driving patterns.
If excessive, review settings for energy-saving modes and adjust driving style to be more efficient.

5. Tire Pressure and Condition

Use a tire pressure gauge to check each tire's pressure.
Inflate tires to the recommended PSI found in the driver's door jamb.
Inspect tires for signs of wear or damage and replace if necessary.

6. Disable Energy-Heavy Features

Turn off any features that may draw excessive power, such as air conditioning or heated seats.
Use the "Energy" settings to activate "Chill Mode" for a more efficient driving experience.
