There is a problem on communication logic between OEM head unit and the later Android version. Software issue, not hardware. I have Pixel 2 with Android 9 and Axon 7 with Android 7. On the CR-V with stock HU, Android Auto on the Pixel 2 keep disconnected randomly while the Axon 7 is stable. On my other car with Pioneer 4200-NEX, same cable, both Pixel 2 and Axon 7 are stable. Both never disconnected. I am pretty sure stealership will blame your USB cable first.
I've had my 2018 EX since March and I have the same issue where it randomly disconnects. After a few minutes of it not reconnecting on its own, I will unplug and replug it back in.
PIA when I'm on the highway and using Google Maps.
Dealer couldn't replicate the problem nor did they find anything wrong with the port. No surprise there.
