The Feburary, the infamous IMA light appeared, and sure enough, autostop, assist, etc, stopped working. I still managed 80mpg the next day dropping the Insight into the dealer. I strongly suspect they were in the "legal CYA mode" when they said you can't drive this car with a dead hybrid batter pack. I had nearly 95,000 miles on it.
They nearly gave me a heart attack stating the battery pack, BCM, and MCM unit would cost $6,500. They later told me Honda would cover all costs above $450. They had it repaired in nine days - very quick compared to stories I've heard.
The two things I believe brought this on was the 2-3 times I let the 12-volt battery go dead, causing the hybrid battery pack to drain trying to save it. The new software (it's a 2000 Insight) might also help prevent this. Also, I drove on the agressive side the first 2-3 years.
Being older and wiser, I expect this new battery pack to last well beyond another 100,000 miles. I have not had a single recal after three months, even driving up the Rockies on I70 west of Denver.
