Oil consumption recall

Had the test , was told come back in 1500 miles , now after 90 miles my cars is at QEC. Being checked because it was sputtering and almost stalled .
dealership upset me so I escalated the issue.
Now they have replaced o2 sensors and coil boots , still diagnosing rough idol .
But the dealership said nope not oil consumption or under powertrain warranty..

Thank god for executive services , they are still working on my baby
