I use the automatic cruise control on my 2018 Subaru pretty much 100% of the time I'm on a highway, and I've never noticed this problem. The only limitation like this that I've noticed is that the range isn't long enough for me to trust it to slow down if I'm traveling at highway speed and there's a stationary vehicle far ahead. Is this what you are referring to? Because I don't think that's the same problem. If I'm not traveling at highway speed in the same situation, I'll let the cruise control do its thing, and as soon as the stopped vehicle is in range, it will start to slow down.
