First off, 02's came with the upgraded computer with better battery management so that's probably the reason for no early model support. The reason for the extension may just be to compete with Toyota's standard warranty or to keep Insight owners happy. From what I've read, Honda has picked up most (if not all) of the bill for battery replacements even before this extension so this might just make it official.

Apparently and "officially" the answer is yes, affirming yout statement. But I doubt for long enough for it to become an "issue" ...
Dead end thread and another effective multi post Troy. Why did Honda :?: The only answer we have is in their letter. Follow-up to the link above if there are other questions that have not already been covered in the thread. But impossible to answer questions are not encouraged.
