The contact owns a 2017 Hyundai Sonata. The contact stated that the vehicle experienced excessive oil consumption with an abnormal burning odor. The vehicle was taken to a dealer, and an oil consumption test was performed. The contact was informed that the vehicle passed the inspection. While driving later, the vehicle stalled and was taken back to the dealer, where it was determined that the vehicle was consuming an excessive amount of engine oil, and several DTC including the Knock Sensor Detection System (KSDS) were found. The contact stated that while driving or reversing at various speeds, the vehicle shuddered, made abnormal rattling sounds, entered HEV Lock Mode, and the vehicle stalled. The vehicle occasionally came to a complete stop in the middle of the road and had to be pushed out of the roadway. On other occasions, the driver was able to pull over to the side of the road. The vehicle failed to restart and was towed after stalling. The contact stated that the check engine warning light was illuminated before the vehicle entered HEV Lock Mode, with several unknown warning lights illuminated. The vehicle was towed to the dealer, where several tests, including bearing clearance tests and unknown repairs, were performed; however, the failure persisted. During the final service visit, the dealer diagnosed the vehicle with engine wear and tear and fractured pistons. The dealer determined that the engine needed to be replaced; however, the service manager informed the contact that there was no guarantee that replacing the engine or catalytic converter would resolve the failure due to severe engine damage. The vehicle was not repaired. The manufacturer was notified of the failure and offered loaner vehicle assistance on several occasions; however, coverage for the engine replacement was denied.
