The problem
Honda (American Honda Motor Co.) is recalling certain 2018-2019 Odyssey vehicles. Loose battery terminal connections or a degraded battery may cause the Transmission Control Unit (TCU) to unexpectedly reboot. Upon rebooting, the TCU may shift the transmission to the "Park" position, possibly damaging the parking rod.
The risk
A damaged parking rod can allow the vehicle to roll when parked, increasing the risk of a crash or injury.
The fix
Honda will notify owners, and dealers will ensure the battery terminal connections are secure and will update the TCU software, free of charge. Additionally, the parking rod effectiveness will be checked. The recall began May 31, 2019. Owners may contact Honda customer service at 1-888-234-2138. Honda's numbers for this recall are Z4J, Y4K.
