NHTSA Complaint #11433465 — 2017 HYUNDAI TUCSON

My car was purchased brand new in November of 2017. It has 71k mikes on it and has been regularly maintained. I began To notice around 50k miles that the oil was brining at an accelerated amount. My car required oil before the designated 5k miles and it would begin “clicking” which alerted me to this issue. September 17, 2021 I was Driving and my vehicle failed to accelerate and began making noises that resembled the oil issue. My car had a full synthetic oil change less than 3k miles ago and by the time I pulled Into my driveway the car stalled. Checked oil and it was low. Added 3 quarts of oil on 9/17/21 and left it to sit. 9/18/21 car started and was driven to car wash and was sitting idle for approximately 45 minutes and on drive home, stalled and had to have oil added again. No leaks were present at anytime and no smoke. Went to dealership where I purchased vehicle and was told they would need to do oil consumption test but that would require me driving it 1k miles up to three times. I explained that my vehicle was breaking down and I was Fearful to drive it. In fact I bought A new car on 9/18/21 and have to get this car fixed to sell. Dealership said this is a known problem and no other way to assess than for me to drive the car the 1k miles and test it. It is still under warranty. I was also informed of an ABS issue that they can fix at same time. While all of these issues are going on, no check engine light or any other diagnostic symbol appears. This makes it hard to even catch before getting to the point of stalled engine. This can be a danger to myself, family and others when car stalls on major highway.
