Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect any external devices or chargers.
Gather tools such as a tire pressure gauge, and a laptop for software checks if necessary.

2. Update Software

Connect the vehicle to Wi-Fi and check for any available software updates.
Follow on-screen instructions to install updates, which may include improvements to battery management.

3. Inspect Battery Health

Access the battery health report through the Tesla app or vehicle settings.
If the battery capacity shows a significant drop, consider contacting Tesla service for diagnostics and potential battery replacement.

4. Tire Pressure and Condition

Use a tire pressure gauge to check the tire pressure, ensuring it matches the manufacturer’s recommended levels.
Inspect tires for wear or damage and replace if necessary.

5. Adjust Charging Settings

Review charging settings in the Tesla app to ensure that the car is not frequently charged to 100%, which can degrade battery life.
Set a daily limit of around 80% for regular use to prolong battery health.
