2015 Hyundai Sonata – original owners. Started burning and engine light came on at 124,000 miles. Took it to dealer to be diagnosed and have oil changed. They called said engine oil was sludged up, they would not even change the oil, and said it needed the engine replaced $9500. We contacted corporate Hyundai who said there was an extended warranty on the engine if the failure was related to connecting rod bearing wear. We were assigned a case and the rep contacted the dealer who said our vehicle didnt qualify. In doing research weve read that this damage cannot be determined without dropping the oil pan. We questioned the rep about this and was told we didnt qualify because of the maintenance on the vehicle.
