NHTSA Complaint #11431670 — 2017 KIA SOUL

Upon startup one day, the engine began knocking. It was turned off and towed. Both an independent service center and Kia dealer have confirmed connecting rod failure, and the need for a total engine replacement. The vehicle is still available for inspection at this time. Fortunately, the issue began when the engine was turned on so the car was not moving at the time of failure, but had it begun on the highway or had a portion of the rod perforated the engine, it could have led to immediate loss of power while in motion and/or leaking oil. There were no warning lamps or messages prior to failure, and the engine had been maintained according to manufacturer guidelines. Periodically prior to this occurrence, the engine did demonstrate temporary reductions in power when accelerating, like it was hesitating to rev up beyond idle speed. However, the local Kia dealer was unable to diagnose the problem at that time (53,293 miles), and simply said to come back if it got worse, giving me the phone number for Kia Roadside Service. Although the loss of power was always temporary and infrequent, it could be a bit surprising when making a right turn into moving traffic, or a left turn across traffic because the car did not move into the traffic as fast as usual, which could have led to a collision with oncoming traffic. Fortunately it never lasted more than a second or two at a time. These symptoms returned the day prior to engine failure in greater frequency and duration. This type of failure is highly unusual for a vehicle of this age (4 years old) and mileage (67,000 miles), and Kia has denied warranty coverage, even though engine issues began before expiration of the warranty.
