The car was parked the night before and not driven the entire next day. I noticed the smoke filled car in the evening. This was a stock 2003 Honda Civic Hybrid the only change from when it came off the line at Honda was the Hybrid ReVolt battery pack. No chargers nothing. Since the new pack was installed this car has operated just fine with no IMA lighs. This vehicle was operated regularly its entire life and always operated fine up to the last day it was driven. The car still will operate in the "by-pass" configuration just fine (if you can stand the intense smoke smell in the car). If I hadn't kept the car closed it would have flamed up and burned to the ground. I am really glad it did stay contained to the vehicle. Matt's latest claim is that the event must have originated external to the battery pack and burned the battery pack in the process. Which is clearly not the case.
