Actually there still seems to be a problem. Today I relearned how to run 
savvycan remotely. What I find is I receive a burst of packets when I 
first connect and then I lose the connection. I tried swapping in my dev 
module but get the same symptoms. For all three of my modules currently 
powered up, the gvret session consistently dies ~7 seconds after connecting.

Thursday I went for a quick drive and got a flatbed alert and I see now 
that with the engine running v.e.on is "no". No idea why the module in 
my CTS-V doesn't have the same problem. (But it is also unable to keep a 
gvret session up.)
