NHTSA complaint #11768938

Owner complaint summary

On September 4, 2026, my son was driving our 2021 Kia Telluride on the highway at approximately 70 mph with cruise control engaged when the vehicle suddenly began making a clicking noise, followed by a catastrophic engine failure. We observed no oil-pressure warning or other advance dashboard warning before the failure. The sudden failure at highway speed created a significant safety risk. I am the original owner. The vehicle had approximately 115,000 miles at the time of failure. Its most recent oil change was performed on June 4, 2026, at 112,613 miles, approximately 2,400 miles before the incident. The servicing Kia dealership reported that the engine had a hole in it and essentially no oil remaining. The oil filter and drain plug were in place, and the dealership reported no external oil leak that explained the missing oil. An oil-filter-housing leak had previously been repaired in January 2026. The cause of the oil loss and engine failure has not been conclusively established. I am concerned about possible excessive internal oil consumption and the absence of an advance warning before catastrophic failure. I request that NHTSA investigate whether this condition affects other Tellurides and creates a risk of sudden engine failure or loss of propulsion at highway speed. Kia denied my initial request for goodwill repair assistance. The case has been escalated, but remains unresolved. The vehicle and failed engine are available for inspection through the servicing dealership.
