Several times I start my car and the radio stations have all been unset, the clock has been unset and the charge in my battery is gone! It turns on immediately and I can reset the clock and the radio stations. I drive for about 5 minutes and all of the sudden there is a full charge in my battery and eveything works normally - this has happened on 4 different occasions???

Might want to check the connectors on your 12V battery. If it gets disconnected it will cause your 144V battery to recalibrate the next time you start up the car. Would also explain why your desk is losing its memory.

When I installed my new deck (disconnecting the 12V battery in the process) I didn't know the 144V battery would recallibrate, it was not a fun moment when I pulled out of my driveway onto the hiway and had no assist :shock:

Loss of electric engine

Thanks - I'll let you know what happens - I took it to the dealer today and got a call a few hours later that they were able to recreate the problem but now they can't get it started and have to confer with engineers at Honda??? It doesn't sound too good - but it's under waranty and I'm glad they were able to witness the problem.

I believe if the 12V battery is dead or disconnected the car won't start. Could someone confirm this?

Yes if the car looses 12 volts the computer will loose track of the battery SOC and will recalibrate. This would also cause you to loose our radio pre sets. You didn't mention the specifics of the car. If it's an older one the little 12 volt is probably just about dead. Insight under hood batteries tend to only last a few years due to the fact that they are never cycled and are always on a float charge. From your description I would bet it's either the 12 volt battery or a bad connection to it.

It was the connection to the battery

You guys were correct - it was the connection to the battery. The interesting thing was that the problem only happened in the afternoon - turns out the connector to the 12v battery was loose - during the heat of the day the connecter became looser and lost contact. In the morning when it was cooler the connection was better and I never lost power. Thanks for answering
