Hyundai Sonata Engine Recall and Warranty Frustration

Hey People! :red_car:

I bought my 2013 Hyundai Sonata with 50,000 miles, did all scheduled maintenance, and kept records. At 89,000 miles, the engine unexpectedly failed. Advantage Hyundai in Hicksville refused warranty coverage, citing gaps in maintenance records despite my efforts to provide more. This model has a known engine recall, yet Hyundai Assurance seems unhelpful. Disappointed in customer loyalty. :triumph:

Has anyone faced similar issues or have advice on next steps? Thanks!
