Got a new 2017 LT, drove it a few hundred miles then had to park it in the garage for a prolonged trip out of town, which I am still on. For about the first two weeks I could check its status with the RemoteLink application, but now it is no longer responding, getting a message: "Hotspot Status refresh failed".

I left it with the traction battery about half-charged and put the 12v cell on a battery tender.

Does OnStar go into a sleep mode after a certain period of inactivity?

Yes, onstar will shut down after a few days to preserve 12v battery power. (it doesn't know you have it on a tender, it's programmed to not run based on time since last vehicle start)

Thanks, canehdian.

On the Leaf, it was 14 days. However, and I don't know if this is true for the Volt, if you remotely used a function that accessed the Telematics, it reset the inactivity timer...
