Have noticed recently (may have always happened but didn’t notice) that when I park the car at the airport or at home (locked, not plugged in) that after a day or two I cannot connect to the car (remote link or Chevrolet app) to check battery status, tire pressure etc. Also the volt stats do not update either after a day or so. The first time this happened I though that perhaps the battery was dead.

After getting back the car always started normally and the communications issues disappeared and volt stats updated again.

Is this normal?
Anyone else notice this?

Parked locations are always in cell phone areas, not a loss of cell signal area

My hunch is it disables the cellular modem so you don't have a dead 12V battery when you come back (12V is required to start the car and only charges when the car is on). I haven't left my Volt unplugged long enough to find out.

After a few days, the On-star module goes to sleep to save the 12 volt battery. The system will wake up every few hours for about 15 seconds so that if On-star is trying to unlock the doors or locate the car but unless your are trying to get updates with the app during those few seconds, it will not update.

Yes, this is normal, working as designed

Back on Sept 2, 2014, I got this reply from OnStar;

edk-austin,

I understand your frustrations. I just wanted to provide some clarification. The OnStar RemoteLink application has a limit to the number of commands you can send, which can be reset by starting the vehicle once again. This command limit is in place to prevent the draining of the battery, as the OnStar system needs to draw power every time it is accessed. I apologize for any inconvenience.

If you want to stay in touch with the car via Onstar while away you should remote start it every three or four days, but you may only want to do that if it’s plugged in. This prevents the Onstar radio from going to sleep as described above.

You can only remote start it twice between actual power cycles with the car's power button.

Thanks, did not know that. I think that the Onstar radio goes to sleep after four or five days, so if you are away for less than two weeks, you could probably start it remote twice to keep it awake.

OnStar goes to standby if car is not started for a few days (5 days?). Newer 4G units are supposed to stay on longer
