Solution

1. Preparation

Gather necessary tools such as a laptop with Tesla service software (if applicable) and a USB drive for data backup.
Ensure the vehicle is parked safely and powered off.

2. Software Update

Connect to Wi-Fi through the touchscreen if available.
Navigate to ‘Software’ on the touchscreen and check for any available updates.
If an update is available, download and install it.

3. Soft Reset

While the vehicle is in Park, press and hold the two scroll wheels on the steering wheel until the Tesla logo appears (approximately 10 seconds).
Wait for the touchscreen to reboot and check if the issue persists.

4. Battery Inspection

Open the front trunk (frunk) and inspect the 12V battery for any signs of corrosion or loose connections.
If necessary, use a multimeter to check the battery voltage; it should be around 12.6V or higher.
If the battery is low, consider replacing it with a new one.

5. Log Review

Use the Tesla service software to connect to the vehicle and download logs.
Review the logs for any error messages that may indicate a hardware failure or other issues.

6. Hardware Check

If issues persist, consult Tesla service for a potential hardware assessment.
Check for warranty coverage, as the touchscreen may require replacement.
