I read some recent discussions that a failed OnStar battery might cause you to have to take your Volt into the dealer if 12 V battery power is removed from the vehicle.
Got to ask the question, is there even a backup battery in the Volt OnStar unit?
As I understand it from a previous thread, OnStar has a little non-rechargeable battery in it.
I was interested in hearing more discussion about this.
Does this just throw an error code or are there worse side effects?
If you aren't using OnStar can you just ignore it and continue driving?
Is the OnStar battery only dealer replaceable?
Is all of this true across all GM vehicles with OnStar?
