car service question

[Danzig]

ok...we own a 2010 crossover. check engine light came on, didn't flash a code.....just on. few days later, it went off.
few weeks later it came on again. seemed to idle a bit rough, and then stalled once (tony always leaves car running when fueling) when tony opened gas cap.
so, take it to dealer. 1146 bucks later, it's 'fixed'. check engine light comes right back on. nothing different, still idling rough. back to dealer. 'oh, now its this, but we won't charge'. pick it up. day later, light back on. back a third time. told them to drive it a few days before we get it back (dealership is 2 hours away) and it seemed after 3-4 hours of driving it comes on. they brought it back yesterday, with a bill.
check engine light just came back on.


so, i am out qbout 15 hours going back and forth, and over a thou in 'repairs' that didn't do squat. anyone know what i should do next? call the car maker?
