Recall repairs done at original dealership(bought new). Passenger seat components that were repaired started an electrical fire under the passenger seat while vehicle was driving. There was a horrible smell inside the car and coming thru the air vents so I turned the ac off and smoke started billowing from under the seat. Immediately pulled over and removed children from car. Vehicle is available. Incident happened with 1 adult 3 kids in car driving. Dealership towed from side of road and kept in service for 54 days(rental provided) and returned with over 1600 new miles on it with no usage of the vehicle told to me and now the affected seat is not connected into the electrical system of the vehicle. Manufacturer did not choose to inspect. No warnings prior.
