   I was sold this car in July of 2025, and I was sold an extended warranty. I didn’t know about the recall, the recall caused engine failure so the warranty company refuses to pay for the new engine and Hyundai refuses to pay for the new engine even though the recall caused it and the dealership that sold it to me refuses to pay for the new engine even though they sold it to me with the open recall please help!

   the car only has 76000 miles on it. there are no check engine lights and the oil has always been perfect and changed on time. There is a known issue apparently with Piston slap that will lead to engine failure. Hyundai refuses to replace the engine, knowing the issue. Driving it puts my safety and others at risk. the Hyundai dealership in Merriam KS has confirmed the issue.
