NHTSA Complaint #11577082 — 2012 HYUNDAI SANTA FE

My 2012 Santa Fe check engine light came on a few weeks ago and put the car into engine protection mode. This car is less than 15 years old, has under 150,000 miles, has had reasonable upkeep. I am only the second owner. I was able to check the code myself and did so. It was P1326, which in a Hyundai vehicle means that there's a problem with the connecting rod bearings and it needs to be taken to the Hyundai dealership while in limp mode. I did so and they replaced the knock sensor, cleared the code, and sent me on my way. The check engine light came back less than a week later, same issue. The dealership told me that at this stage the Hyundai tech repair line suggests replacing the engine at an enormous cost. However, because my car can pass the BCT (bearing clearance test) Hyundai will not pay for the replacement of the engine because it cannot be said that the connecting rod bearings are the issue. When I asked why I needed to replace the engine, the service advisor was unable to explain which part of my engine was broken and just that it all needed to be replaced or the car would continue to show code P1326 and go into engine protection mode, rendering it unusable. This has been incredibly unsettling for me as a recently separated mother of two. I have been without my vehicle and without income for weeks while trying to contact Hyundai. They are claiming this repair has nothing to do with the THETA II engine recall out for my model year. All advisors have been pressuring me to purchase a new vehicle, but I do believe the reason I cannot use my vehicle is because of the THETA II engine defects and the P1326 code that will continue to render my car unusable. This code when cleared without fixing the problem, has caused my car to go into engine protection mode (unable to accelerate past 2,000rpm) on the freeway, which was dangerous for myself and other drivers on the road as well as terrifying.
