Question 2014 SRT Idle issue

Does anyone know if the 2014 GC SRT has the Economy Cylinder Deactivation System on the 6.4 / 392 Hemi?????

When I come to a stop light, after I sit there a minute or two, the engine noticeably sounds like and feels like something has either turned on or off, and then the engine begins to idle with a kinda high frequency vibration that is very noticeable, it stays that way until you accelerate...

As soon as you step on the gas, the engine and vehicle accelerate normally, it doesn't seem to effect the drivability. I haven't taken it back to the dealer as yet to see about this, but I was thinking that if it has a cylinder deactivation system, perhaps when idling for a period of time, it deactivates a few cylinders to improve economy, and thus the idle quality suffers from not running on all 8 cylinders...

If anyone has the same issue or any insight, I would love to hear about it....

So it is written, So shall it be done !
