This thread started by "JoeReal" smells of BS and is bordering on trolling or at least trying to get a rise out of the less experienced or uneducated Volt owners.
It is impossible, with the stock HV battery in a Gen 2 Volt to get that number of miles unless you are driving some sort of "fixed" loop with no stopping, using cruise control and driving at well under standard speed limits, or driving downhill and charging at the bottom (or you have faulty software for your guessometer).
Please fully describe your problem or your style of driving so that new owners here will not be misled.
