The company currently doesn't have a fix for the issue, but it says it's working on one. In the meantime, Honda will be making available to owners additional information on ensuring the seats are properly installed. Honda is also notifying owners via mail of the issue.
This isn't the first time Honda has had issues with the second-row seats in the Odyssey. Last year, Honda issued a major recall and stop-sale on the Odyssey for a different latching issue. In that case, the latch mechanism that allowed the seats to move forward for easier third-row entry didn't always secure the seats after they were moved back. This increased the risk of injury in a crash, though no injuries were reported related to the issue.
