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.

Cars need to go full bluetooth for connectivity with smart phones in my view. Putting wireless charging plates in cars and not putting in full bluetooth connectivity is an oxymoron move by auto makers. But I get it.. technology moves more incrementally in many car designs, rather then in broad range additions. IF a company puts a wireless charging plate in a car.. it should come with full bluetooth connectivity.. and not just one bluetooth channel, but multiple channel support.

I'm not saying USB ports do not have some value in applications inside cars.. just that the mechanical interface of a gen 1/2 USB port was never designed in the USB standards for environments with bumps, vibrations, etc. It was originally designed to easily mate peripherals to static computer setups. Perhaps the newer generation USB port standards are better for this.. but I have not seen evidence one way or the other yet. That said.. a properly designed device OS would be resilient to minor glitches in connection via USB. iPhones appear to be pretty resilient for this.. some Android phones.. not so much.

The later Android Auto version is wireless, my Pixel 2 automatically open AA when BT connection is established, just the HU is not supporting it yet. Some new ones do: JVC 845, Kenwood DDX9705S, etc.
