Hi there! I understand your myBuick app isn't indicating that your vehicle's battery is dead and is showing no issues. Let's dive a bit deeper so I can assist you better.

Could you please tell me if your vehicle is actually having battery problems (like not starting or electrical issues), but the app still reports no problem? And are you able to connect the app to your vehicle normally otherwise? Also, have you tried any troubleshooting steps with the app already?

Sometimes the app may not detect a dead battery because it relies on vehicle data sent via cellular or OnStar connection, which might not be updated if the battery is too low or disconnected.

Here’s a step-by-step plan we can try:

1. Force Refresh App Connection:
- Log out of the myBuick app, then log back in to refresh your vehicle’s data connection.
- Ensure your phone has a strong internet connection during this process.

2. Check Vehicle’s OnStar System:
- Press the blue OnStar button in your vehicle to verify that OnStar service is active and communicating. If it’s unable to connect, that might prevent battery status updates.

3. Disable Power Saving Features on Phone:
- Turn off any “Do Not Disturb” or “Power Saving/Low Power Mode” on your phone, as those can limit app background activity and notifications.

4. Verify Vehicle’s Battery Status Manually:
- Check your vehicle’s dashboard for battery warnings, or use a multimeter to test battery voltage. A healthy battery usually reads around 12.6 volts when the engine is off.
- If you find the battery is indeed dead or low, the app might just not yet reflect that.

5. Update or Reinstall the myBuick App:
- Sometimes, an app update or reinstall helps clear bugs that prevent accurate data reporting.

If after these steps the app still doesn’t report the battery issue, it may be a limitation in the current software or vehicle communication. In that case, you might want to contact an OnStar Advisor at (877) 558-8352 for further diagnostics or visit a Buick service center to evaluate the battery and the vehicle’s telematics system.

Would you like me to guide you through any of these steps one at a time? Or do you already know the battery is dead and want help with starting or access tips? Let me know!
