Having only had my Volt for about a week, this is the main set of issues I've had as well. Sometimes the iPod connected via USB plays appropriately, and sometimes the startup sound is missing and there's silence while the screen says the iPod is playing. Changing sources usually fixes it. Sometimes Siri works by holding the steering wheel button, and sometimes it doesn't. Sometimes it receives and broadcasts my incoming texts, and sometimes it doesn't. Lots of little gremlins and annoying quirks in the infotainment so far.I have had numerous weird things happen related to the infotainment system on my 2017 Volt.
