I've seen numerous posts on various forums about this issue. Over the past few months I intermittently have no audio in my 2017 LX570. It can go days or weeks and e everything works fine. Then boom, no audio, no volume indicator, no voice command, and no power to the rear seat entertainment. This happens when I start the vehicle and usually resolves after parking it for a while. Being that it's random, the dealership can't diagnose it. I'm able to pull codes B15D0 and B15D3. I've seen posts where the issue was permanent, but never intermittent like mine. Has anyone else experienced this?
