NHTSA recall 19V299000
Electrical System, Power Train · Honda (American Honda Motor Co.)
Details
What's wrong: 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.
Why it matters: 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.
