NHTSA Complaint #11709713 — 2014 KIA SOUL

Summary of Safety Defect: While my 16 year old daughter was driving our 2014 Kia Soul in December 2025, the car suddenly lost power in traffic and would not go over 20 mph; the check engine light came on and the vehicle entered limp mode. The sudden drop in power created a high anxiety, hazardous situation for my daughter, who had only had her license for a week, during rush hour traffic. The vehicle was unsafe to operate and had to be towed. Details of the Incident: Diagnostic trouble code P1326 (Knock Sensor Detection System) was confirmed by the Kia dealership. P1326 is part of Kia’s known engine defect population and is tied to safety related engine failures. The dealership documented oil consumption, oil fouled spark plugs, and compression readings below Kia’s minimum specification on all cylinders. The dealership concluded in writing that engine replacement is required. Despite this, Kia denied warranty coverage based solely on a bearing clearance test, without completing the full diagnostic process required under the KSDS settlement. The vehicle remains unsafe and inoperable. Why This Is a Safety Issue: The sudden loss of power and inability to accelerate above ~20 mph created a dangerous situation for my daughter and surrounding traffic. This is a known defect pattern in Kia vehicles covered under the KSDS program. The failure occurred without warning and could have resulted in a collision. Requested Action: I am reporting this because Kia has not responded to my two complaints nor properly addressed a safety related engine defect that is already part of a national settlement. The incomplete diagnostic process and denial of coverage leave the vehicle unsafe and unusable. I request that NHTSA review this incident as part of the ongoing safety concerns involving Kia GDI engines and P1326 related failures.
