NHTSA Complaint #11697033 — 2020 KIA SPORTAGE

While driving uphill on Interstate 15 North near Temecula, California, the vehicle suddenly lost engine power without warning. My speed dropped from approximately 75 mph to around 60 mph in heavy traffic. This unexpected loss of acceleration created an immediate safety hazard, as vehicles behind me were traveling at freeway speeds and I was nearly rear-ended. I had to maneuver from the far-left lane to the shoulder while the vehicle continued to lose power. Once stopped, the check engine light was flashing, and the engine temperature gauge showed extreme heat, raising concern for a potential fire. The vehicle was towed to a Kia dealership, where technicians confirmed a complete engine failure and recommended a full short-block replacement. The vehicle has been regularly serviced and has more than a dozen documented service visits, including visits for ongoing oil-consumption concerns. Despite this, the low oil warning light never illuminated when the engine oil level was low; the only alert that appeared was the routine maintenance reminder. The lack of a low oil warning contributed to undetected oil loss and sudden engine failure. This failure occurred at approximately 92,000 miles and mirrors previously reported engine and bearing defects in similar Kia models. The vehicle and documentation are available for inspection upon request.
