Solution

If your Tesla Model Y's vehicle settings keep resetting, this could be a sign of a software glitch, a problem with the vehicle's battery, or an issue with the vehicle's central processing unit. Below, I will provide a structured approach to diagnose and potentially resolve the issue.

Step 1: Check for Software Updates

Tools Required: Tesla mobile app or the vehicle’s touchscreen.
Procedure:
- On the vehicle’s touchscreen, navigate to ‘Software’.
- Check for any available updates. If an update is available, install it.
- Restart the vehicle after the update to see if the settings issue persists.

Step 2: Power Cycle the Vehicle

Tools Required: None.
Procedure:
- Put the vehicle in Park.
- Press and hold the two scroll wheels on the steering wheel until the touchscreen turns black.
- Once the Tesla logo appears, release the scroll wheels. This will reboot the vehicle's computer system.

Step 3: Check Battery Health and Voltage

Tools Required: OBD-II scanner or Tesla Diagnostic Tool (if available).
Procedure:
- Connect the OBD-II scanner to the vehicle's OBD-II port (usually located under the dashboard).
- Check for any error codes related to the battery management system.
- If battery voltage is low or diagnostic trouble codes (DTCs) are present, it may indicate battery issues.

Step 4: Inspect Vehicle Settings

Tools Required: Tesla mobile app or vehicle’s touchscreen.
Procedure:
- Navigate to ‘Settings’ and check all relevant settings (driver profiles, display, and climate) for any anomalies.
- Ensure that the vehicle is saving these settings properly by changing them and checking if they revert after a power cycle.

Repair Instructions

If the Issue Persists After Diagnostics:

Step 1: Reset All Settings

Tools Required: Vehicle touchscreen.
Procedure:
- Go to ‘Settings’ > ‘Service’ > ‘Factory Reset’.
- Follow prompts to reset all settings. Note that this will restore factory settings and erase saved profiles.

Step 2: Contact Tesla Service

Tools Required: Tesla mobile app or phone.
Procedure:
- If the problem persists even after a factory reset, contact Tesla support through the Tesla app or website.
- Provide detailed information about the issue, any error codes, and steps you have taken to troubleshoot.
- Schedule a service appointment if necessary.

Conclusion

Persistent resetting of vehicle settings in a Tesla Model Y can stem from software issues or hardware problems. Following the steps outlined above will help you diagnose and potentially fix the problem. If all else fails, contacting Tesla support is the best course of action to ensure your vehicle receives the appropriate attention.
