2013 Cat and 02 monitor not ready
I have a 2013 volt. And for some reason my Cat and 02 monitors will not set. I do not have any faults in the vehicle. I have done driven the vehicle. In mountain mode for a week and in Hold mode for a week still nothing. I used a snap on scanner and recorded the engine sensor data. When reviewing the O2 sensor are reaping correctly. The pre 02s switches about one a second and the post O2S stays steady @ .75v Is this a known issue for volts? If so what is done to correct it?

You need to run the battery down and run on gas for some set period. Went through this with my 2012 when it got a recall flash at the dealer just before emissions test. I ran battery down and did a freeway run of about 30 miles. That clear down to one code not set and I got it through emissions.
If you have a SnapOn, you should be able to set those monitors to "ready" with the tool. Last time I checked, my SnapOn Solus could do it.
William, Did you ever figure out the issue or resolve it? Having the same problem with our 2013 Volt.
