[Volt Owner]

Two interesting things happened today, for the first time in 6 years, that I think may be related:

1. The center screen seemed to lose communication with the clock: It didn't display the current time, and pressing the 'TP' button gave the "set clock" screen, but there was no time displayed, and the set clock buttons didn't do anything.

2. We have time-of-use electric metering. Electricity is more expensive starting at 5:00 p.m. I plugged the Volt into my level 1 charger when I got home at 4-something. At 5:00, I got a message from OnStar telling me that charging had been interrupted.

Yes, I expect charging to interrupted at 5 p.m., because that's when the rates go up. However, I didn't expect OnStar to tell me so, because it never did that in the past. Could this be because OnStar didn't know what time it was?

When I powered the Volt on, the clock seems to be back to normal.

Not to incite anything, but are you still running the original 12V battery? It's common for a failing 12V battery to manifest in unusual computer behavior. That said, I can't say I've had any clock issues with my '13 and I don't normally have the charge set to anything other than "charge immediately" since I just pay a flat rate throughout the day and holding off on charging doesn't impact my bill. It would make sense to get a message from onstar about a charge interruption, but I was under the impression that didn't occur if you had it set to only charge during specific hours but rather only due to loss of line voltage from either a wall disconnect, or if the handle was removed from the charge port.

1. Can't speak to this one. Gremlins.

2. That's not normal. When the schedule ends and it's not done charging it should just stop and go into delayed mode (flashing green). You'd then enter your car to see it 80% full (or whatever the number is)
The charge interrupted message is normally for when the car is unplugged while actively charging or there is a failure in the electrical supply (power outage, voltage drop, etc) that interrupts. It shouldn't matter what time the clock says.

Dollars to donuts it's a 12v battery problem. Mine was original issue until last week, first time in the shop for me. Lots of weird little issues. They were fixing something else, but I asked them to check and replace the 12v battery. They tested it, it wouldn't even start the car - it had been right on the edge of failing for some time.

Sure would be nice if people included basic stuff like the year of their car, miles when they post issues...

Seeing that in the first line the OP stated "for the first time in 6 years" which would put it at an '11 or '12. But I certainly agree that minor details such as year and mileage help tremendously when trying to help diagnose issues.
