The contact's husband owns a 2015 Hyundai Sonata. The contact stated while the vehicle was at an independent mechanic for an oil change, the contact was informed that the vehicle was experiencing excessive oil consumption and that it was a known failure. Additionally, the contact stated while driving 73-74 MPH, the vehicle shuddered and stalled. The contact was able to pull to the side of the road. The vehicle failed to restart and was towed to an independent mechanic, where it was diagnosed that the rod bearing had caused engine failure. The dealer determined that the engine needed to be replaced. The mechanic informed the contact the failure was due to a factory defect and would reoccur even after the engine replacement. The vehicle was taken to the dealer, where the same assessment was made. The dealer filed a claim with the manufacturer and sent a diagnostic report with pictures of the failure; however, the manufacturer denied the claim several times. The contact stated that the engine was previously replaced. The manufacturer was notified of the failure. The failure mileage was approximately 152,550.
