What are my next steps to diagnosing oil over-consumption 2017 Hyundai Santa Fe?

Hello, the problem with most third party warranties is that they don't generally cover internal engine concerns like stuck piston rings or valve concerns that cause oil consumption. They consider that wear - not failure of components. 3.5 quarts. in 1,000 miles is almost enough to see oil running out the tailpipe - that's a ton! How many miles on your Hyundai? Did you buy it new or used? Sometimes you could have recourse with a Hyundai dealership - have you asked them? You're in a difficult position to be sure; hopefully you have a repair shop working with you helping you navigate?
