My 2017 Deserthawk has begun bucking and chugging like a bull. I thought maybe it was just some bad gas. Ran it down to half a tank and refilled and a ways up the road, it threw a service light. Doesn't matter the speed. Idle, 30, 70 - it's bucking about. Other than the stupid mysky roof sticking, I haven't had any problems and I just crossed 52k. Anyone had a similar issue? I dropped it off at dealer early this morning but I've heard nothing from them.
