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.
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
