NHTSA Complaint #11666930 — 2025 HONDA ODYSSEY

On June 14th 2025, I reversed up my driveway, uphill, shifted to neutral to allow the vehicle to roll downhill a bit so I could straighten it out. While rolling forward, the transmission was jammed into park with no warning or interaction from me, causing my head to sling forwards in a whiplash fashion from the abrupt change in inertia. This was both harmful to me, to the transmission, and is a major defect. Engaging a transmission into park while moving is reckless, harmful and extremely dangerous. The failing component is most likely the transmission control unit and is available for inspection upon request, but has not been inspected by anyone other than myself. The problem is reproducible by me.
