Kia Engine Settlement-Kia America and Grand Forks KIA dealership is refusing a mandatory diagnostic test for excessive oil consumption under the Kia Theta II Engine Class Settlement, despite the vehicle having the required KSDS software update installed. The vehicle is consuming 1 quart of oil every 1000 miles, requiring constant topping off to prevent engine seizure. Vehicle was brought to Kia Grand Forks on 7/21/25 was told that the valve gasket needed to be changed. Engine light illuminated 10/2025 and car was unable to make it back to dealership from 58369. Vehicle was brought to local mechanic where I was told that the has failed and that the spark plugs had oil on them. Mechanic changed the spark plugs to make it to Grand Forks Kia on 10/14/25 I was told that the Turbo needed to be replaced for $3300 before they can do an oil consumption test. There were no issues with the turbo before it was driven to Grand Forks on 10/14/25.
