At 93,693 miles, the engine check light and the IMA light appreared. The autostop would not activate. Battery indicated full charge, but the Assist/Charge bar was out. Car drove normally and even seemed to have less of a performance drop off then when it recals (that has no occurred in about three months). Got 80mpg on my 25-mile work commute this morning without an IMA. Lute Riley in Richardson took several hours and $250 to find out: IMA battery - out MCM - out BCM - out Codes: 1644 and 1600 The estimate cost for parts and labor was $6,400. Warranty for the 2000 Insight was 80,000. After discussions with the Service Manager, a deal was made that Honda would pay for all but $450 and my rental car. Hopefully the batteries and unit will be superior to the OEM. Heard horror stories of waiting 1-2 months for a battery pack, so a 9-day turnaround is not bad. I was driving a KIA Rio with an automatic for a rental. Did not get a chance to fill it up, but I went 131 miles on the last fillup and used as much as four gallons - nearly 33mpg. That's the EPA combined estimate. It will be awhile to determine if there is any change in performance, but it appears unchanged. I paid $449 for the repair - Honda covered the remaining $6,000. I paid $343 for the rental. My resolutions is to never let the 12-volt battery go dead (last time the hybrid battery pack went dead trying to save it). Also, don't plan to use the Assist for longer than 30 seconds - i.e. moderate use.
