NHTSA Complaint #11715134 — 2020 KIA TELLURIDE

For some time, I was noticing that my 2020 Kia Telluride was consuming excessive amounts of motor oil - at least one quart per 1000 miles. I have had my car serviced regularly by a certified reputable mechanic and scheduled oil changes and other required service every 5000 miles. At around 69,100 miles the check engine light appeared and I immediately took the car in for service. I was advised that the spark plugs and valves were heavily carbon fouled. The spark plugs needed changing and the valves needed cleaning. It was also necessary to replace the coils. Total repair bill was $2008.84. I was advised by my mechanic that excessive oil consumption is a problem with KIA automobiles and after researching the issue myself, found this to be the case. Some engine design issues, most likely with oil leaking past the pistons into the combustion chambers, causing fouling. I have learned that ultimately, the pistons and valves will become fouled again, the engine warning light will reappear and possibly, the engine will break down - hopefully, not in a distant place without knowledgable service. The new car warranty for my KIA was 100,000 miles but since I bought it used (I am the second owner) the warranty was reduced to 60,000 miles. I filed a complaint with KIA Motors and asked that they simply extend my warranty to 100,000 miles but since there is no pending recalls for this problem, my request was denied.
