No, it was only changed in 2021.

Since I imagine others will be confused, this does not refer to the seats folding flat into the floor. Rather, it refers to the seatback folding flat against the seat bottom for easy removal.

Why would they change the seats mid model to NOT fold flat? What's the point in that?

They changed them mid model to fold flat. 18-20 models did not fold flat, 21+ models do.

That was stupid of them to remove the fold flat feature. Having lugged our '15 seats in and out several times, and having pulled the seats out of my '99 camaro a few times that obviously don't fold flat, well, the Odyssey seats are definitely easier to remove flat!

Probably something that slipped through the engineering changes when they implemented magic slide.
