NHTSA Complaint #11647188 — 2017 HYUNDAI TUCSON

My 2017 Hyundai tucson is consumeing oil at a steady rate. Took it to dealership roughly year to do oil consumption test. They said my headgasket, turbo, and pil pan was all leaking. They replaced those parts before starting oil consumption test would be performed. $3,300 later still consuming roughly 1 quart per 500 miles. It faild the oil consumption test and i was advised to do a combustion chamber cleaning next. $700 later and im burning 1 quart roughly every 1k miles. Took it back to them and said thats normal and it is fixed. I'm very concerned considering no car should burn that much oil in between 3k oil changes and only holds 5 quarts of oil. I also have 2 young children and wife that regularly drive the car and it's sluggish when getting on the gas like entering the highway and I'm worried the engine may just go out of nowhere. My local dealership doesn't really care nor does corporate. This is my last ditch effort to get something done. I know I and many, many, many, others are also dealing with this and something needs done soon. Thank you for your time.
