We left our new 2018 Volt Premier at a friends house New Years Eve for obvious reasons. The next evening, Jan 01 we went to pick it up in -10C weather. The battery was completely dead, no lights at all. Nothing. But the doors were unlocked? Called onstar via cell phone. 2.5 hour response time for tow or jump.

We decided to jump ourselves. Hooked up the cables and the car came back to life and started up. Drive battery was almost full. Couldn't tell if the 12V was actually dead or just off line...

I got in to drive and noticed the instrument cluster had changed. Similar to the modern enhanced but there was a new feature with the speedometer now a modern take of the traditional dial speedo's, a small needle that moved around the graduated center circle of the instrument Cluster. I then figured that this was a pushed update to the car that maybe caused the battery to either go flat or just glitch the 12V system and wouldn't start up. See my crude drawing of the new display. IMG_2329.jpg

Either way, we took it home and plugged it in. The next day when we used the Volt, the instrument display changed back to the original Modern Enhanced display and the speedo update was gone, and cannot be found.??? But the car did start with no problems!

Anyone else experience this? or do I have old Instrument Cluster software, and the update wasn't completed.

Thanks,
We are new Volt owners, and new to EV's

Did it look like this: https://i.pinimg.com/originals/bd/a2/ff/bda2ff785aea1a1407976e2fc106b302.jpg ?. If it did, what you where likely seeing was the dash display and computer using part of the display theming/elements for the Cadillac ELR. Which uses the same display and computer hardware.

There have been a few reports of this. In some cases the dash completely changed to the Cadillac theme, but then reverted back to the Volt theme after a shutdown.

Also, if your 12v battery was dead already. You might want to have the dealer check it. There have been a few cases of faulty 12v batteries.

Like stevenwm mentioned, this has been reported in the past specifically with regards to either losing connection to the 12V battery or the battery being dead.

There must be a lot of DNA shared in the software between the Gen2 Volt DIC and the ELR. A software glitch triggers the ELR display to be shown on screen. Personally, I like the ELR display and would welcome having it as an option that could be selected for the Volt but I'm pretty sure that is not in the cards.

Thanks guys. We are new to the EV market and the Volt.

That is exactly it. The center speedo was identical to your photo and the battery indications etc. were on either side. And yes it is quite a nice display. Too bad it wasn’t an option. Quite strange how it appeared then was gone on the next startup.

Thanks for answering my question that was already asked.

I’ll inform the dealer of the issue ASAP

I have had our 2011 Volt 12 volt battery go dead once. It hasn't happened again in ~ 7 years so I have to assume that I did not properly turn the car off. I believe my wife had the key in her purse and got out and away from the car before I turned it off. Without the remote in the car it takes two pushes of the on/off button to turn the car off.
