VIN: [XXX] 2021 Hyundai Kona experienced sudden engine failure at approximately 103,000 miles. The engine began knocking without any prior warning, and the check engine light came on at the same time the knocking started. The vehicle was not driven for an extended period after the issue began. There were no earlier warning indicators or drivability issues that would suggest neglect or lack of maintenance. The failure was immediate and unexpected. This vehicle had previously received Hyundai recall T8Y, which involved an ECU update related to engine monitoring and performance. Despite this manufacturer intervention, the engine still experienced sudden failure. Hyundai has denied warranty and goodwill coverage for this failure. This appears to be a premature engine failure and raises concerns about reliability and safety due to the sudden nature of the issue.

I am reporting a persistent and unresolved excessive oil consumption issue that I began to notice at approximately 61,000 miles. I follow all routine maintenance and oil change schedules, but my car has returned to the dealership I purchased from (only owner), three times for this specific problem. - First Visit (64,074 miles): I shared my observations of excessive oil consumption to the dealership, they stated there was an oil leak at the timing cover and oil pan. They repaired the leaks, however this did not resolve the consumption issue. - Second Visit (65,273 miles) - The oil change done by Mobil at 75,238 miles, before I brought my car in for the third time to Hyundai for the consumption issue, documented that my oil level was at the 'Low'(L) level, this is the case each time I get an oil change around 3,000 miles - The third time bringing my car to Hyundai my mileage was at 78,913, less than 3,000 miles since my last oil change. Before making the appointment my cars engine sound...

The vehicle has 82.000 miles on it, and the engine started to rattle as I entered the street to my house, and the motor quit running. I had the vehicle hauled to a repair garage for analysis, and they said the piston rings failed. The vehicle is in perfect shape except for the broken engine.
