Android Auto Volume Annoyance/bug

[mccmw]

This issue has bothered me since my previous Pixel phone...and has continued on my current Pixel 9 Pro and Android 16. For some reason when I connect to Android Auto in my vehicle, at some point it increases my call volume to maximum. If I'm not careful, and don't manually turn it back down when disconnected from the vehicle, I'm greeted with a nasty surprise (earache) the first time I put the phone to my ear! Is there a setting I'm missing or can I stop Android Auto from messing with my phone volume? Known issue or something I should send a bug report to Google?
