NHTSA Complaint #11619501 — 2018 HYUNDAI TUCSON

my mechanic and I noticed that motor oil engine is running out too fast that is normal. I take my suv to do oil change every 5,000 miles, I can't even wait the 5,000 miles because the oil level is low, he double check for any dripping of oil. my mechanic told me that it is not safe drive the car in low level of oil because it can cause a fire in the engine. I went to the hyundai dealer to explian them the problem and they told me there is nothing they can do to fix the issue because my manufacture guarantee is over, I don't feel safe to dive my car in that condition so thats why I'm here making this request to hopefully you guys can help me. the most important thing is the safe of my family.
