I had same issue when I first got truck, then deleted my Bluetooth connection (my phone) and WiFi (my home) I initially programmed in and then reinstalled them. No more problems (5000 miles - 3/4 year). Not sure which one solved the problem.
Same here on Day 1 of ownership. Pixel phone didn't lock up but the Infotainment system did. After deleting the BT connection in the truck & the Pixel, and a reboot of both, I haven't had any connectivity issues. The phone connects to the truck and the stored music on my phone starts shuffle play via BT within 10 seconds or so.
This happens to me sometimes using my Motorola MA1 wireless android auto dongle. Usually rebooting radio solved it. Most times it works fine, this just happens every so often. My Motorola MA1 usually takes at least a minute or so to connect. Seems like most people say their's connects much faster. I am using the USB c port for the Motorola as I have a music USB stick in the USB a port. I haven't tried deleting and reinstalling the Bluetooth or WiFi connection. Might try that but like I said it seems to work fine, about 8 out of 10 times usually.
