NHTSA Complaint #11705180 — 2013 KIA SORENTO

I am submitting a formal written complaint to supplement my existing NHTSA Safety Report ID 11702339 regarding a serious fuel system defect on my 2013 Kia Sorento. My car began experiencing sluggish starting, sputtering during acceleration, stalling at stop signs and traffic lights, and a strong fuel odor. A check engine light subsequently illuminated, and due to safety concerns, the vehicle was towed to a Kia dealership for diagnosis. The dealership confirmed and documented fuel leakage from the high-pressure fuel pressure regulator and fuel contamination in the engine oil. This defect presents a serious safety risks: increased risk of engine fire due to fuel leakage, unexpected loss of power while stopped or in traffic, and increased likelihood of a collision due to engine stalling. This vehicle previously had its engine replaced under a Kia recall in 2020, making this failure particularly concerning. Fuel system failures and post-recall engine-related defects have been the subject of multiple Kia recalls, service campaigns, and NHTSA investigations involving engine fires and fuel leaks. Despite the dealership's documented diagnosis and clear safety implications, Kia Consumer Affairs denied recall coverage and refused to assist with repair costs, stating this is not a recall-related issue. The estimated repair cost exceeds $1,700, and the vehicle remains unsafe and undrivable. Given the confirmed fuel leakage, fuel contamination of engine oil, prior recall engine replacement, repeated stalling events, and Kia's refusal to acknowledge responsibility, I respectfully request that NHTSA review this case as part of a potential defect trend, particularly involving high-pressure fuel system components on Kia Sorento vehicles with prior recall engine replacements. I am submitting this complaint to ensure this safety issue is formally documented, investigated, and considered for further action to protect consumers. Thank you for your attention to this serious safety matter
