Amusingly a poster above indicated they had issues with multiple Subarus, and another had issues with Hondas (which is what has worked well for me).
People on this forum want it to be a technology issue, and I'm sure it is to some extent, but I think the differences between driving styles is also a large component. If you're a careful driver that usually leaves a lot of separation, many AEB implementations will rarely trigger and you'll usually understand why when it does. Whereas if you're an aggressive driver that cuts between vehicles, leaves <1 s separation, etc., you will notice a lot of "unexpected" braking from these systems. Like the poster above that was upset the system slowed them down when they were nearly clipping a car exiting the road.
