Thanks for posting your experiences. Thankfully, knock on wood, we have had no trouble with ours and most iMiev owners seem to be pretty happy with the car too (perhaps the unhappy ones don't bother to post here ??). Of course there is bound to be some glitches with all these new EVs, more so than with ICEVs that have generally had the glitches worked out. I sometimes visit the i3 or Leaf forums, and there are plenty of problems and horror stories to read through, so I don't think the iMiev is unique in this regard.
Anyway, I just wanted to say thanks for sharing. It helps us owners, and potential buyers, know what to expect and prepare, or negotiate, for and hopefully learn from those problems. I think that Mitsubishi will abandon the iMiev once the PHEV Outlander comes to market (2016 sometime?) while the iMiev is not seriously marketed or sold; perhaps it was/is just a way for Mitsubishi to improve the electric drive train so that the PHEV Outlander will be a more solid product.
