Engine Failure

2017 Hyundai Sonata, on a road trip this weekend for my birthday and start feeling shaking when changing gears. Stop to take it into a shop, they tell me it has cylinder misfire. After a compression test they realize the piston rings are failing and tell me I need a whole new engine. Engine replacement exceeds value of the car, it's totaled. Had to tow the car to storage, and buy a flight home. Hyundai says it's not covered by warranty. I financed this car 18 months ago and still owe. I feel robbed.
