Solution

1. Battery Health Check

Access the Tesla app and navigate to the battery health section.
If health is below 80%, consider contacting Tesla service for potential battery replacement.

2. Driving Habits Evaluation

Review the trip summary in the Tesla interface.
Adjust driving style to optimize energy consumption, such as avoiding rapid acceleration and heavy braking.

3. Tire Inspection

Use a tire pressure gauge to check the pressure of all tires.
Inflate tires to the recommended pressure (usually around 42 PSI for Model 3).
Inspect tires for uneven wear; replace if necessary.

4. Software Update

Connect to Wi-Fi and check for available software updates in the vehicle settings.
Follow prompts to install updates, ensuring the vehicle runs on the latest software for optimal efficiency.

5. Climate Control Assessment

Monitor the usage of the climate control system; excessive use can drain battery quickly.
Use seat heaters instead of cabin heating when possible to conserve energy.

6. Visual Inspection

Check for any obstructions in the wheel wells or undercarriage.
Remove any debris or items that may be affecting aerodynamics.
