The rear sliding power door on the passenger side closed on my six year old child. He was trapped in the door and could not move until I opened the door. He has pain and visible injuries on his back from the door. This happened on 2.10.23. There have not been any incidents with the van leading up to this incident. This happened when the van was parked in the garage and the engine was off. We have not tried to replicate the incident because it caused an injury. The vehicle is available for inspection.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2016 Toyota Sienna verdict →
