Solution

1. Preparation

Gather tools such as an OBD-II scanner, tire pressure gauge, and basic hand tools.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Update Software

Connect the vehicle to Wi-Fi.
Navigate to the software settings on the touchscreen.
Check for updates and install any available software improvements.

3. Battery Inspection

Use the Tesla app to check the battery's state of health.
If the battery health is low, consider contacting Tesla for a battery assessment and possible replacement.

4. Tire Maintenance

Use a tire pressure gauge to check each tire's pressure. Inflate to the manufacturer’s recommended PSI.
Inspect tires for uneven wear; replace if necessary.

5. Brake System Check

Lift the vehicle using a jack and secure it with jack stands.
Inspect the brake calipers and pads for any signs of sticking or wear.
Replace or service the brake components if they are found to be faulty.
