While driving vehicle at approximately 45 mph, engine stalls in middle of busy highway. Was able to get vehicle to side of road in the rain. Vehicle would not start and was towed to dealer. Dealer calls to say engine is blown at 37k miles. Dealer was last to perform oil change. No issues were noted at that time. Awaiting to hear if engine is covered by extended engine warranty that was issued by kia as they are well aware of this problem and has known for several years.
Vehicle experiences the same issues that are also happening on Hyundai sonatas with their engine recalls. While traveling at highway speeds of 50-60 mph and then accelerating, the engine may sometimes jerk/sputter as if about to stall. This may be due to the fact that the engines were not cleaned properly while being manufactured, leaving mechanical debris within, as stated by the Hyundai engine recall investigation. This can become a major concern as the car could potentially become unresponsive on the highway or even slow down/ stop suddenly in the case that the engine may stall.
