As far as I know, on the 2011 and 2012s a few of the cars suddenly saw this failure and it's probably waiting to happen to all the others "some day". On the 2011 I own I'm seriously considering pushing hard for a pro-active replacement before the warranty expires - and when they (likely) turn that down I'll probably go in for the extended warranty just for this part.
Why you think the 2011/2012 problem is "an accident waiting to happen"? My understanding is that it was sort of an "infant mortality" problem: either the bad (batch?) of parts failed quickly (as in the first year) or there wasn't a problem. Luckily, I appear to be the latter (already verified working heat this winter) although I purchased an extended warranty when I bought my Leaf.
