Solution

1. Preparation

Gather tools and materials required for inspection and repairs.
Ensure the vehicle is parked on a level surface and turned off.
Disconnect the battery (if necessary) following Tesla's guidelines.

2. Update Software

Navigate to the vehicle’s settings menu.
Select 'Software' and check for any available updates.
If an update is available, initiate the download and installation process, ensuring the vehicle remains connected to Wi-Fi.

3. Adjust Autopilot Settings

Access the Autopilot settings through the vehicle display.
Review and adjust settings such as 'Traffic-Aware Cruise Control' and 'Autosteer' to ensure they are properly configured.
Consider disabling features temporarily to see if the phantom braking issue persists.

4. Clean Sensors and Cameras

Use a microfiber cloth and a gentle cleaning solution to clean the forward-facing cameras and ultrasonic sensors.
Ensure that all cameras and sensors are clear of dirt, debris, or moisture that could affect performance.

5. Inspect Brake System

Remove the wheel covers (if applicable) using a socket set.
Visually inspect brake pads, rotors, and calipers for wear or damage.
Check brake fluid levels and top off using the recommended fluid type if low.

6. Reset the Vehicle

Perform a soft reset of the vehicle by holding down both scroll wheels on the steering wheel until the touchscreen reboots.
Once the system restarts, test drive the vehicle to check for improvements in braking behavior.
