In my humble, uneducated opinion, I'm pretty sure the handful of pack failures I've read about are exactly that - An 88 cell pack which experiences even the failure of one single cell will eventually require the entire pack to be replaced. If you sell a thousand cars with 88 cells in each of them, a handful of defective cells in those 88,000 is to be expected, I thinkmradtke said:Could it simply have been a defective pack?
I'm sure when the defective 'pack' gets back to Mitsubishi, they analyze it and replace the one or two cells and they do something with the repaired pack - Could be that some of their replacement packs are actually recycled low miles packs which have been repaired and tested
I really doubt that anything any user is doing will cause any pack to fail in the first few thousand miles . . . . I suspect all of those are just packs with a bad cell which were going to fail anyway
But, to reiterate Joe's position - I want to drive my car for 200,000 miles if possible, so I'll never treat it 'like any other car'. I will always do whatever I can that I *think* might be better for the battery - It's not a major inconvenience for me and hopefully it will pay off in extended battery life once we're beyond the factory 100K warranty
