NHTSA Complaint #11477265 — 2014 HYUNDAI TUCSON

On 7/29/2022 we took a trip with a 2014 Tuscan from from Boise Idaho to Worland WY. About 2 hours past Pocatello in a town called Kemmerer Wyoming the vehicle started to knock in the engine. As this happened the Vehicle started to derate its self from 80 MPH to 50mph and wouldn't accelerate past 1500RPMs. We pulled over and checked the oil and found metal on the rag used to check the oil. Ran a code reader and it read P1326. That means The Knock Sensor Detection System is tripped. In 2020 they fixed the sensers on most vehicles using the GDI engine because they would have a faulty trip. The tell tale sign that it wasn't a faulty senser was the engine knock and metal in the oil. We drove two hours the night before and didn't notice anything out of the ordinary. I would get oil changes every 3k to 5k miles. I checked fluids the night before when I left Boise. This issue came up with no warning. Turns out Hyundai has a life time warrantee on the GDI engine because they have major problems. They was a 1 Billion Dollar Law Suit against Kia/ Hyundai for issues during the manufacturing. This issue applies to the Hyundai Sonata, Santa Fe, Tucson and Kia Optima, Rio ,Sorento ,Soul and Sportage. Make sure to call Hyundai/Kia and they should replace the engine free of charge or give you a option to trade even if you DO NOT have a warranty. I attached a link that should prove to be helpful in researching this issue. https://www.safetyresearch.net/hyundai-kias-billion-dollar-engine-problem-that-broke-the-nhtsa-civil-penalty-barrier/
