NHTSA Complaint #11531032 — 2011 HYUNDAI SONATA

I received a code through my ECM reading P1326 or a knock sensor code. They “diagnosed” my vehicle and gave it back to me after just replacing the knock sensor. After driving it for a week, the code came back and said it just needed an update. Then, the same thing happened, so they rediagnosed the vehicle and turns out there’s a hole in my engine but didn’t mark it under the recall warranty because the hole in my piston wasn’t due to a rod bearing issue. My problem is the Hyundai dealership giving me back a vehicle that is very unsafe to drive not once, but three separate times. For all I know, my engine could have seized any moment and the dealership wouldn’t have taken accountability for anything in regards to having to transport back and forth to their offices.
