Oh (gasp!) who could you two possibly be talking about?
It wouldn't (gasp!) be the same guy who in the very first reply to this very thread said that the battery in Volts would be needing replacement "soon", would it?
I just checked my 2011 with ~170,000 (and counting) KM on it, almost 4 years after that reply. Yep, original battery, still working great.
Sadly, it doesn't guess what direction I want to go, so I have to manually move a shifter lever like a mere peasant.
And when the heated seats controller crapped out GM fixed it under warranty, they didn't say it was a "wear item" and have the computer lock the seat heaters to the "High" setting and tell me that was a failsafe setting.
Bumpers and roof also still firmly attached as well!
