NHTSA Complaint #11685326 — 2017 KIA SEDONA

On [XXX], while driving my 2017 Kia Sedona on a road trip through Killeen, Texas, the engine suddenly began making a loud knocking noise without any prior warning, leading to catastrophic engine failure and complete loss of motive power. The vehicle became inoperable and was towed to University Kia in Waco, Texas. The day prior, on [XXX], the vehicle underwent a thorough pre-trip inspection and full synthetic oil change at Sun Auto Tire & Service (5117 Golden Triangle Blvd., Keller, TX 76244), confirming it was roadworthy with no issues detected initially, though oil was found leaking afterward (maintenance records attached). University Kia confirmed the catastrophic engine failure, likely related to the 3.3L Lambda engine's known oil pressure switch (OPS) defects, as the OPS had been previously replaced under warranty. Kia Motors America (Case [XXX]) denied liability unless I pay $3,000 for a teardown inspection to prove the failure was due to the OPS, despite the vehicle's eligibility under the WTY026 extended warranty (15 years/150,000 miles). This failure aligns with similar complaints and NHTSA investigations into 3.3L Lambda engine issues, such as oil starvation and sudden seizures. Due to the failure, we missed a prepaid hotel stay in San Antonio, incurred additional hotel stay charges as our trip had to be extended, and incurred costs for a rental vehicle to complete the trip.
