Being I am in Virginia, 5 spd manual tran, ULEV, 99K+ miles I have more than enough strikes against me to get rejected by the Honda dealer for warranty work on the IMA battery
. Another strike might be not being the original owner. It would be great to see the statistics (avg and "1 sigma" in miles to IMA battery failure (as measured by the car and/or stated/collected by the Honda dealers) for 2003-2005 models (other posts indicated Honda slightly changed the battery for 2006 and later models by adding extra cells and changing the control system/program to extend battery life by changing the end points on battery use at the expense of gas mileage). I'm sure Honda has the data. Was it a good business decision for them to extend the warranty to 10/150K in certain states in order to get the "certification" in those states?
Well the dealer price of $30 for a relay is probably consistent with the price of $60 for an on/off clutch switch
I am just thankful the car I have is sort of a hobby item for me right now (until someone in the family needs a replacement anyway). This is certainly less stressful than if it was my everyday car that I had to depend on each day.
There is info on AC items over on the Honda Tech forum if you end up having to go beyond the relay replacement in the AC system to diagnose your problem. My current intermittent AC problem seems to go beyond just depleting the 12V overnight.
