NHTSA Complaint #11575127 — 2011 HYUNDAI SONATA

November 2021 I was coming home from work when the engine started making a horrible noise. I limped the vehicle home and contacted Hyundai and was told to bring the vehicle in to the dealership. It was stated that Hyundai had closed the campaign on the knock sensor the week before bringing it in, but they would try. About a month later the dealership called and said that I needed to come get the car due to they were selling the dealership lot. I towed it there and towed it home and have continued to peruse actions to correct the lifetime warranty that is offered due to shavings left in the engine when manufactured. Found another recall that said my vehicle is affected by this recall and to scheduled a service appointment. When delivering the car back off yesterday at the new dealership that took over, I was informed that the recall would probably fail due to another recall that had never been preformed, which is a recall that I had never been presented with by mail or communication of any sort. This was in the middle of the global pandemic when the world was shut down, and I have never been presented with any recalls from Hyundai. They may have sent notification through the US POSTAL SERVICE, but never came in to my possession, knowledge or mailbox. The contact stated Hyundai refused to proceed with the recall on the vehicle due to the fact that contact had done his own oil changes. The contact is requesting assistance to get Hyundai to honor their obligation.
