1 Crankcase (pcv) problem

Failure Date: 04/13/2026

In December of 2025 at approximately 95,000 my 2021 kia Telluride (VIN [xxx] ) showed the oil level was about two quarts low. My car has had regular maintenance including oil changes at santa fe kia. At the next oil change appointment in March, I pointed out the oil consumption concern. At that point kia recommended an oil consumption test be performed. The car had 96,700 miles at that point. At 97,700 kia indicated that the oil level was fine. At 99,600 I checked the oil and discovered it was more than two quarts low. I called santa fe kia to address the issue and they indicated that a quart every 1,000 miles is within kia standards and recommended another oil consumption test which would take me over the 100,000 warranty. I called kia customer care to address the issue. A case was opened, but they kept referring me back to the dealership to be dealt with. After researching the issue myself, I presented the well known and documented oil consumption issue amongst kia consumers to include pcv valve and piston ring issues. I have an appointment scheduled for 4/16/26, but I am being told that I will be liable for the cost of the pcv valve replacement, compression test and oil leak test which are all known issues related to the problem. Santa fe kia's service manager is ignoring my request to submit an engine warranty claim citing that they didn't find a problem outside of kia's acceptable oil consumption and kia's customer care refuses to open a claim and keeps referring me back to the dealership. I will be at approximately 99,850 when I arrive at my appointment on 4/16/26. I am concerned that the engine has a major issue and will be told that my warranty is over by the time the issue can be determine and resolved. I am also concerned that there has already been engine damage done without noticing the high oil consumption. Information redacted pursuant to the freedom of information act (foia), 5 u. S.
