I bought a 2019 Hyundai Tuscon in 2020. Never owned a Hyundai but the warranty was "the best in the business". I loved it, the way it drove, the features, the way it looked inside and out. One problem though, the car has gone through 5 catalytic converters in the last 2 years. It has been at a Hyundai service department 6 out of the last 8 months. The catalytic converter has been replaced 4 times. The timing chain and the cylinder heads have been replaced by my extended warranty(Not Hyundai). They don't know what is causing the catalytic converter to go out so I have 3 options: 1st option is to replace the engine for around 12k. 2nd option is to pay 4k up front for a complete tear down of the engine to find the root cause, then hope my extended warranty(Not Hyundai) will pay to repair it. My extended warranty doesn't cover the catalytic converter so Minimum of 7K. The third option was to go pick up the car, engine light on and needed a new catalytic converter. I chose the 3rd option since I don't have 7-12k. I begged, pleaded and threatened Hyundai to help with the repairs and they responded by saying"We decline to offer any financial assistance". I don't have a clue what to do now. I can't sell it or trade it in and I can't drive it . I have a loan on it so I am screwed. My advice is not to buy a Hyundai/Kia product so you don't end up in a situation like I am in. Their "best in the business" 10yr/100k warranty was useless. My car is the exact definition of a "Lemon", this is 100% an engine defect. I know that sounds harsh but this has been the most stressful, upsetting and frustrating experience I have ever been through. I still love the car but just wish I could drive it.
