This is now the second time that we are having a rear hatch failure. with about 37,000 miles on this van, the control module shorted out due to water getting into it due to a bad seam (according to other Odyssey owners who are suing Honda for this).

The car had a leak in the trunk that was not our fault it was not due to an accident but rather came that way when we bought it brand new. We were unaware of this leak and now our entire trunk control panel is flooded and the trunk is totally useless as it will not open at all, not even manually. The only way to open it is to crawl to the back and open it from the inside.
