NHTSA Complaint #11545673 — 2017 HYUNDAI TUCSON

My 2017 Hyundai Tuscon excessively consumed oil. I took it into Hyundai of Kirkland. I was informed an Oil Consumption test would be completed by the Service Advisor, Chris Z. First I had my oil changed, then I was told to bring the car back in around 1000 miles. the first time I brought the car in, I was over 1000 miles. Chris informed me he would rather me bring the car back in under 1000 miles than over 1000 miles.
