2017 Sonata Sport 2.0T
Did a Hyundai Dealer do the engine replacement or did you have an independent shop do the repair / engine? if it was done at the dealer you would be the first owner Ive heard of that did not get a free replacement, it should have warrantied and you should not have paid anything up front.I have owned 3 Hyundai vesicles. Currently have a 2015 Sonata that without any notice, the engine burned. Although the car was still under warranty, they have not reimbursed me for the new engine replacement that cost me $5,095. I put a reimbursement request in in beginning of September. Clearly they have had mechanical issue that occur right after the car hits 60K miles. I will never buy another Hyundai again. They DO NOT stand behind their manufacturing issues or their customers.
Now if you had an independent mechanic / garage do the replacement then I can see where you may run into delays or possibly even denial from Hyundai.
Were there other factors involved, did you have service records to show the service schedule was followed.
