Constant Speed Sputter

My 2012 Arcadia, when you are driving at a constant speed (and not using cruise control) will shudder/sputter. If you stay the same speed for a bit it constantly shudders/sputters.If you give it some gas or let of the gas it resumes normal operation and runs smoothly.Any thoughts on this are appreciated.

Firstly, check the spark plug gap. If the plugs are worn, you can have this symptom. Otherwise, a faulty coil. The ECU will not always store a code for misfires like this. Lastly, it could be a transmission issue. Unfortunately, it's common on these and it may be a solenoid causing incorrect shift or seals bad. hope this helps
