NHTSA Complaint #11689470 — 2015 HYUNDAI TUCSON

I started having oil issues 3 years after purchasing my hyundai Tuscan 2015. I took my vehicle to hyundai several time all of which I was told by service guy and I quote “Hey its Hyundai, just following up so right now we have a consumption issue. It is currently 2.5 quarts low. The tech recommends re doing the oil change and returning in 1000miles and recheck. When you return and we see that the oil level is more than a quote low then we would have you reduce the service interval from 5000miles to 3000miles, let me know if you have any questions. I had many questions and also wanted to know why it was my responsibility to do all these things if they know the engine is faulty. Had another diagnostic and the code P1326 populated. That means indicates an issue with the Knock Sensor Detection System (KSDS), often pointing to actual engine knocking caused by worn connecting rod bearings, but also potentially to a faulty knock sensor, wiring problems, outdated ECM. The Theta II engines are documented to have clogged oil galleys, preventing proper lubrication and causing premature wear. They do everything the can NOT to fix the issue even with a lifetime warranty on that engine.
