I would say the chances are very remote.

GM's pack is a extremely conservative design. We will find the pack is good for much more than the 100000 mile warranty.
In the future (IMO) we will see GM maintain the 40 mile AER but decrease the pack size from 16 kwh (by increasing DOD). In this way they can reduce the wt and cost of the Volt.
I also would expect the hackers will find a way to change the software to increase AER but your warranty would be in jeopardy.
