I have a 2007 Honda Odyssey which has been pretty trouble-free, about 62,000 miles. I was away for three weeks and the battery drained completely. I charged it up overnight with my neighbor's charger. Battery took about half a charge. When I plugged in the charger the alarm went off, but after putting in the navigation code it quieted down. The next day I drove off for an errand and the alarm light started flashing on the lower right corner of the dash, and the alarm went off when I stopped and opened the door to get out, but was silenced by hitting the door lock button on my key fob. Then on the way home there was no turn signal, no power lock, no outside temperature indicator, no low speed windshield wiper, no rear wiper, no fluid pump. Then I restarted and a few of those things were restored, like the power locks and the outside temperature. Since I was near the dealership I stopped by and they checked all the fuses - all were OK. Made an appointment, min. of $140 for them to diagnose Monday. Drove again today, Sunday, and outages come and go, even as I drive along. Saw a bulletin for a similar problem due to water damage. Although it rained while I was gone, no sign of water inside. Computer problem?
