I bought anew Hyundai Sante Fe sport either April or May of 2018. This past spring i got a recall notice for a knock sensor update. Brought it in for that, it's first inspection and i had a free oil change too. About 500 miles later i was on the interstate with the cruise on and it kicked the cruise off and started bucking and had a lot less power. Brought it in and they said it was common after the update and needed a new wiring harness. They gave me a loaner and they had it fixed in a few days. Today i was bringing the wife to work and it did the same thing and the weird part was it did it in the exact same place on the interstate. Brought it to the dealer when they opened, they gave me a loaner and said they would call if there was any major issues or when it was done. He just called and said the performed a test and the engine failed so they are replacing it. Just under 12k on the car! To me it just seemed like an electrical or fuel issue, no knocks, pings or any other noise, just a lack of power and felt like the throttle was cutting out. Not going to argue with a new engine though.....
