I tested the '18 Odyssey and the door reversed with just the slightest pressure on my arm. The Pacifica scared me a bit with how much I had to push back on it to get it to reverse. Just my experience and only on the one Odyssey.
Its kind of scary that the Pacifica has to be pushed back with some force for the automatic door stop to work the way it should. It really makes me wonder how safe kids are dealing with these doors, hopefully its an issue that is resolved soon.
