Hmm I haven't had that problem, instead my bug is with the "BOTH HANDS ON THE WHEEL!" warnings.
The thing is basically driving itself so why can't I just rest my hand(s) at the bottom of the wheel--very annoying. I don't like cruise control in the first place so this really fries me.
You have two different "modes" of BlueCruise, and which one is on will depend on the road you're on and its conditions. If it is a BlueCruise mapped road, you never need to put you hands on the wheel and it will drive all by itself. If you are on a divided highway, but not one that is BlueCruise mapped, the car will do most of the work, but still requires you to have your hands on the wheel. (And, honestly, the latter is not BlueCruise, it's just normal adaptive cruise control with lane centering.) It can also require hands on if lane conditions are poor or in construction zones.
If you are constantly getting an alert to put your hands on the wheel, you are not in an area or a condition in which BlueCruise is available. It's easy to tell from the appearance of the dash...
1) if the whole dash is blue: BlueCruise is on, no hands required
2) if the dash is normal and the lane lines are just marked in blue, you are not in a BlueCruise area or it is not available for one reason or another.
Your profile says you are "up north"...here is the BlueCruise Map:

If you are not driving on one of those highways, BlueCruise is NOT available on that road.
