The contact owns a 2014 Hyundai Santa Fe sport. The contact stated that while driving 63 mph, the cruise control was activated, and the rpm fluctuated between 2,200 and 3,500. Additionally, there was a burning odor detected, and lots of smoke was coming from the exhaust pipe that filled both directions of the street. The vehicle was taken to the dealer. The dealer diagnosed that the pcv valve had carbon and that the spark plugs were corroded with carbon. The dealer performed an oil consumption test but did not complete the test due to the spark plugs needing to be replaced. The dealer informed the contact that the pcv valve and spark plugs needed to be replaced. The dealer removed the pcv valve; however, the vehicle was not repaired. Prior to the failure, the contact had an engine block code that was reset twice without repair. The manufacturer was made aware of the failure and a case was opened. However, the manufacturer notified the contact that the case was closed and was sending out documents to the contact. The failure mileage was approximately 128,127.
