Honda Odyssey may roll away after being parked

NHTSA campaign 19V299000 · Reported 2019-04-12 · Honda (American Honda Motor Co.)

high How serious is it? About this label

Serious — a van that rolls on its own can injure someone or hit another vehicle; you can keep driving, but until it is fixed set the parking brake every time you park.

What's wrong, in plain English

On these Odyssey minivans, a loose battery cable connection or a worn-down battery can make the transmission's computer restart on its own. When it restarts, it can shift the van into Park while it is still moving, which can damage the small rod that locks the parking gear. If that rod is damaged, the van may not truly hold in Park and can roll away after you walk off. Dealers tighten the battery connections, update the software, and check the parking rod, free.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to confirm your Odyssey is included.
2. Contact your Honda dealer, or call Honda at 1-888-234-2138, and mention recall Z4J or Y4K.
3. Have the battery connections, software, and parking rod checked — all free of charge.
