I have a Pixel 6 pro and Peugeot 5008 GT and Android auto doesn't work at all. Sometimes it is connected for few mins before it gets disconnected again. It's the same on my previous Pixel 3 XL too. I think the recent update broke this as it had been working since a year on my P3XL. I have sent several bug reports and tried all the troubleshooting steps on official and non official forums. It seems to be a widespread issue and there is no fix yet ? Btw Apple carplay works flawlessly !
