Cruise Control won't set
I have a new 2016 RT-S. Cruise shows "ON". Press the cruise button down to "set", and about 1 out of 10 times it will set. Took back to dealer, they say nothing wrong. Brought it back. Set the first time out. Went through a round a bout. Tried to reset, wouldn't set. Turned cruise off and back on, still wouldn't set.

First place I would check would be the brake light switch. If switch is on cruise won't work. Is your foot making any contact with he brake pedal? It doesn't take much to activate that switch.

I would agree with that. If the brake light is on the cruise will not set.

I would have thought the dealer would have checked that

I used to have the same trouble with my 2014 RT. Mine did that for the first 300 miles or so, and then it worked fine.
Skip ahead to the first 3k mile service. After putting it on the computer, it stopped working again. After 300 miles, it was fine. After that, it never gave any more trouble. Dealer or myself never found the problem.

You said you went through a round about, what was your speed when you tried to resume the cruise? If you were going too slow it may not engage.

The throttle needs to be steady to work best. Cruise won't set if you are accelerating or decelerating. Especially it won't set if you are accelerating under load or decelerating with throttle backed all the way off.
