My engine has failed, and my steering wheel column has locked. I had the software update on my engine with Napleton that qualified me for a lifetime engine replacement. I submitted maintenance records for my car and pictures of my valvetrain that are well maintained, and hyundai denied my engine claim for exceptional maintenance neglect on Dec8. On December 14th, after reviewing my oil changes, they still denied me for using low quality oil that's obscured. The problem I am having with my car is oil, not being able to get to the pistons inside my engine. It's not fair when the company know they engines have a manufacture defect. Then they blame the customers for lack of maintenance to have an excuse not to replace the engine. Knowing that with or without oil changes in the hyundai sonata 2011 -2012 models the engines will eventually seize anyway.I've reached out to their company over 300 times trying to resolve this matter and I'm still in the same place I started at a month ago. I want to sue for pain and suffering. I've been without a car since nov 9, and it's dec 20. Hyundai has put me and my family life in danger on numerous occasions, with their faulty and defected parts causing two near death experiences. Hyundai sonata has had a recall on every part, and I consider them unsafe and dangerous. I have seven different case reports with Hyundai motor company about excessive oil consumption, and the knocking whining vibrating and shaking. They are very much aware of everything

I dropped off from the highway and checked the engine and there was a smoke coming out from the engine it was scary. I took my car to the dealership and they took some time and they said I have to replace the engine.

In May 2022 the engine was recalled and replaced by Schomp Hyundai located at 100 Havan St, Aurora, CO 80010, and I purchased this car right after the engine recall. Since I bought the car vehicle the engine has been making noise and the AC and heater smell gas and burned fuel inside the vehicle through cabin air vents. I took the car to the Schomp Hyundai and asked them to fix the noise problem as the engine is not properly installed but they refused to fix it and asked me to pay $180 to diagnose the problem and to pay additional for the fix. The second time when I took the car for the gas and fuel fume and I was told that it is not part of the engine warranty; I have to pay $180 to diagnose the problem and pay additional for the fix. As the engine was replaced, the service may have resulted in damage to the high-pressure fuel pipe. While maneuvering the engine into place, the fuel pipe may have been crushed, poorly torqued, or simply not aligned properly. The dealer is not accepting any responsibility.

My vehicle should be covered under a recall for my engine, however Hyundai is denying the claim due to my title being branded as salvage, however according to my research a salvage title does not affect the recall. I believe my engine should be replaced, and Hyundai is refusing to return my calls at this point.
