NHTSA complaint #11744031

Owner complaint summary

My 2021 Kia Telluride (approximately 82,000 miles) suffered catastrophic engine failure caused by excessive and abnormal oil consumption. The engine consumed oil at a dangerous rate with no warning lights or dashboard indicators of any kind. The only symptom prior to failure was an unusual engine noise. There was no opportunity to take corrective action before the engine failed completely. This failure occurred while I was driving with my children in the vehicle, creating a serious and immediate safety risk. A sudden engine failure at highway or city speeds — with no prior warning — presents the risk of loss of vehicle control, inability to accelerate out of traffic, and potential collision. The failure has been confirmed by two independent service centers: Vanguard Kia in Arlington, Texas and Christian Brothers Automotive. Both confirmed engine failure. The vehicle and failed components are available for inspection upon request. Kia America has declined to provide warranty assistance or goodwill repair coverage despite this being a widely reported issue among 2021 Telluride owners with the same Lambda II V6 engine. No recall has been issued. Repair cost is approximately $11,000. I am still carrying a loan on this vehicle. I am requesting NHTSA investigate this as a systemic safety defect and consider a mandatory recall.
