What can I do to make the Hyundai dealership replace my engine while I’m still under warranty?

I have a 100,000 mile warranty for my 2017 Hyundai Tucson. I have 2500 miles until it runs out. I am currently in my second “oil consumption” procedure. I have paid $2700 out of pocket for a catalytic convertor due to being over the mileage for coverage, I found out after the fact it was not that but my engine burning oil and a fast rate which would be covered under my power train but I keep getting the run around. I’m technically still under the lemon law period for a brand new car being the original owner. I have maintained routine maintenance over the almost five years the car has been in my possession. Every time I go to the dealership, I beleive I’m getting half truths and then they continue to do things to restart the process in which I speculate they hope I run out my warranty.
