A "batt low see manual" light and warning beep occurs on my Honda Odyssey 2011 since purchase. My Honda dealer has charged the battery and checked the software without solving the problem. I have also reported to Honda headquarters. Honda has not fixed this problem. The odyclub and edmunds townhall forums are full of others reporting this problem. Honda's recommendation is simply to drive the van more rather than find a resolution for this issue.
