NHTSA Complaint #11667368 — 2019 HYUNDAI KONA

This vehicle was sold to me advertised as a certified pre-owned by Somersworth Hyundai in New Hampshire. They have since shut down and I now see that they have a long history of bad reviews and scamming. When I had my first issue with this car, I brought it in thinking that it was covered by a certified pre-owned situation only to find out that it was not. I had a rare, bizarre, and expensive transfer case replacement done and was forced to pay out of pocket. Now, my check engine light has been flashing for about a month. It also started having a slight stutter or shudder in low speed acceleration. It hesitates or feels like I let off the gas for a split second even though I didn't. This happens everyday. I had the spark plugs replaced and that did not turn the flashing check engine light off. The service shop that installed the new spark plugs printed out an nhtsa recall bulletin on my vehicle for piston oil rings that may not have been properly heat treated which could result in engine damage. Consequences being damaged engines may stall and increase the risk of a crash. As well as oil leaks may leak on to hot exhaust components increasing the risk of a fire. Hyundai dealership and Hyundai corporate. Both say there are no open recalls on my exact vehicle. It is not included in this recall. I need the diagnostic process including knock test performed on this vehicle.
