“The contact owns a 2016 Kia Sorento. The contact stated that after starting the vehicle, while driving to the residence, the coolant temperature gauge went from COLD to HOT. The contact inspected the vehicle and became aware that smoke was coming from the engine compartment. The contact waited for the engine to cool down before driving to the residence. The coolant reservoir was extremely low, and coolant was added; however, the engine continued to smoke, and the coolant reservoir was empty after an hour. The vehicle was taken to a certified mechanic who diagnosed and determined that coolant was leaking from the coolant reservoir. The coolant reservoir was replaced; however, the failure returned within 5 minutes of restarting the vehicle. The mechanic then diagnosed the vehicle with complete engine failure. The vehicle was towed to the dealer, where the contact requested information on a Limited Extended Warranty Extension and a recall; however, there was no coverage for the repair. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case. The failure mileage was unknown.”
