A friend of mine was driving from NY to Florida last week in his 2016 Kia Sorento with the 2.4 engine when his engine self destructed in North Carolina. He bought the vehicle new and did regular maintenance and had 126K on it. He had it flat bedded home and is awaiting an estimate because he was told the rebuild wouldn’t be covered under warranty. Needless today he isn’t happy. What should the cost to rebuild it be? He said it started making a knocking sound and lost power and he limped to an exit which luckily was close by.
