NHTSA Complaint #11521063 — 2016 HYUNDAI SONATA

I purchased a 2016 Hyundai Sonata 2.4L with the Theta II engine back in December 2016. I purchased it as a Hyundai Certified Pre-owned (CPO) vehicle, with the 10 year, 100,000 mi powertrain warranty. The car had approximately 36,000 mi on the odometer. Starting at about 60,000 mi on the odometer, I began to notice excessive engine oil consumption. The factory has made attempts to remedy the issue under the 10 year, 100,000 powertrain warranty coverage, but none have lasted more than 1,000 mi. After 1,000 mi of a "repair" service, the engine is back to consuming lots of engine oil. As a result, I have resorted to checking the dip every time I fuel up, and top off engine oil as it gets consumed. To my estimate, my oil consumption is between 200 to 300 mi per qt of oil consumed, which is well in excess of the factory acceptable levels of 400-500 mi per qt of oil consumed. Then, Hyundai USA's Customer Care's customer reps, case managers, and Hyundai National Managers all have told me in several occasions over the past two years that my car is either "out of warranty" (despite not yet having reached the 10 year, 100,000 mi mark, nor the extended 120,000 mi mark) or that Hyundai has never sold any Hyundai CPO cars with the 10 year, 100,000 mi powertrain warranty in the US, despite my sales records and owner's records indicating that my car came with the warranty. Hyundai is trying to breach its 10/100 powertrain warranty contract and trying to have me pay for the diagnostic and repair costs out of my pocket.
