Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect any chargers and turn off the vehicle.

2. Tire Inspection and Maintenance

Check Tire Pressure
- Use a tire gauge to measure the air pressure in all tires.
- Inflate tires to the recommended PSI indicated on the driver's door jamb.
Inspect Tire Condition
- Look for uneven wear or damage.
- Rotate or replace tires if wear patterns are irregular.

3. Software Update

Access Software Settings
- Navigate to the "Software" section on the vehicle's touchscreen.
Check for Updates
- If an update is available, follow the prompts to download and install.
- Ensure the vehicle is connected to Wi-Fi during the update process.

4. Battery Health Check

Inspect 12V Battery
- Use a multimeter to measure the voltage of the 12V battery (should be above 12.4V).
- If the voltage is low, replace the 12V battery.
Battery Conditioning
- Charge the vehicle to 100% and allow it to discharge to 20% to recalibrate the battery management system.

5. Professional Inspection (if necessary)

If issues persist after performing the above checks, schedule a service appointment with Tesla for in-depth diagnostics and potential battery replacement.
