To have closure on this posting
I visited my Dealer about a month after I picked up our new 2014 Miev and asked the service manager what happened with my 2012 Miev I traded in.
He said they changed the 3rd OBC and his mechanic drove it daily for about 3 weeks,
They recently sold it and it seems there is no problem with it.
I asked him what was the cause of the problem.
He came back with that he believes it was the EVSE upgrade I had done.
With the last OBC failure, it lasted 3 days, and I never even used my upgraded OE portable EVSE.
Reflecting on the recent epidemic of OBC failures in our forum.
Horsefeathers - I just shook my head and walked away.
I guess we will never know what was the cause.
