With Dynamic Cruise Control, the car will brake to keep from overspending. If you are on shallow hill, it will feel like a quick pulse. On a steep hill, you may feel the brakes being applied almost continuously.
Worth paying attention to the behavior and watching if the speed is being reduced when this braking happens. It would be a normal function of the cruise control.
At higher speeds, air resistance does not require much more than lifting off the throttle to slow the vehicle on fairly flat roads.
It can be somewhat odd, until you get used to it. Especially if you don't normally use cruise often, tend to forget about it. Took me some time to get used to it, and now I take advantage of it. Will set the cruise on a steep hill and let the car do all the work.
The OP did not mention Cruise Control, which would explain the braking behavior comments.

There is a clue in your post. 'Cruise Control.'

Sad to say.. I have the same problem when "im in control". Feels like the brakes engage for a moment and then its gone. Everyone can feel it in the car.
