Again with misinformation and lack of knowledge on subject :).   If that was the case in 10 years and my battery was caput I could drive on my ICE as the Volt comes with both.  

In researching the Volt before buying what I discovered was that the overwhelming majority loved theirs....and the Gen 2 was a step up...  lighter, more range etc.     So those vehicles are nearing 10 years and so far no bad press I am aware of.
