Engine Check Light

I have a 2012 Ram 2500 ST with a 6.7L Cummins Turbo in it. It's got right at 79k on the engine. I just bought this from the dealer less than a month ago and I've had it in the shop 4 times due to the engine light coming on. The second time, they replaced the O2 sensor on the catalytic converter. Light came on a week later again; took it back and they said they had to replace the Oxygen sensors and would order them. The fourth time in to have sensors replaced. It's been a week and today, the engine came on again! I think they are parts changing instead of fixing the problem. The only positive about all this is they are doing under Chrysler warranty since I just bought this from them.
Can anyone give me an idea why the light keeps coming on? I thought maybe the gas cap was loose; but after taking it off and putting it back on, the light is still on.
When the light came on; the truck seemed to "caugh", if that makes sense. It runs great once you're cruising; but tends to hesitate while shifting.
Ideas?
Thanks,

This bulletin involves the installation of an Oxygen (O2) Sensor Overlay Harness for any
