I have 67K miles, and I've been experiencing a recal about once every two weeks. I've been keeping a log of every recal since the start of the year, and have had the dealer I use check it once so far (the invoice indicates the battery pack was operating "normally" and they fully charged the IMA battery before returning the car to me, but no real change in behavior). I'm due to take it for normal service and the headlight recall soon, and I'm going to ask them to check both the IMA battery and the 12V under the hood. I figure I'm gonna have them check it every time I take it in, and will bring my log and graphs in hoping that maybe somehow I'll end up with a new IMA battery if needed prior to the warranty expiring. We'll see how it goes.
