Hello Frankly0919,
A helpful article for unexpected CarPlay issues can be found here: Use CarPlay with your iPhone - Apple Support. You might want to try forgetting your car and then setting it back up, as that can help refresh the settings.
Updating your iPhone to the most recent iOS version can help with this behavior. Follow this guidance:
Update your iPhone or iPad
“1. Back up your device using iCloud or your computer.
2. Plug your device into power and connect to the internet with Wi-Fi.
3. Go to Settings > General, then tap Software Update.
4. If you see more than one software update option available, choose the one that you want to install.
5. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now."
We also advise that you make sure your car firmware is updated. Check your car manual or reach out to the car manufacturer for those steps.
We hope this helps. Let us know if we can assist with anything else at all. Take care.
