Solution

1. Brake Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake components.
3. Inspect the brake calipers for proper movement; look for signs of rust or debris.
4. Check the brake pads for wear; replace if they appear worn down or if they are sticking to the rotor.
5. Lubricate the caliper slides if necessary.

2. Tire Check

Sub-steps:
1. Measure the tire pressure using a tire gauge and inflate to the manufacturer’s recommended levels.
2. Inspect the tire tread for uneven wear and replace tires if necessary.
3. Rotate tires if uneven wear is detected to ensure even distribution.

3. Software Update

Sub-steps:
1. Connect the vehicle to Wi-Fi.
2. Navigate to the software update section in the Tesla app or vehicle settings.
3. Download and install any available updates, following on-screen prompts.

4. Regenerative Braking Test

Sub-steps:
