NHTSA Complaint #11564633 — 2016 KIA SOUL

My family decided to purchase a 2016 Kia Soul and it was a great car until it stalled on me on a highway, and funny enough I was helping my father on his vehicle on the highway. I had this car towed to Raceway Kia at Freehold NJ , who provided a KDKS software update to the engine. A short time later, the car had to be sent again and they performed an oil consumption test. By this time, my car was near the warranty expiration of 100k and they stated that since I performed this, that if there were problems with my vehicle, they would fix it. Fast forward and now I am experiencing a knocking in my car and it is losing acceleration/ power. I sent my Kia Soul to another dealer, Matt Blatt Kia at Toms River. They diagnosed the engine and stated that there were no engine problems or codes and that I need a new catalytic converter that costs over $3000. This is not fair because there is research that supports that because there is engine problems with this model, this could contribute to catalytic converter problems. I am aware there is an ongoing settlement that qualifies my 2016 Kia Soul, and know that others have had their engines replaced. Links: [XXX] [XXX] What should I do next? I do have the receipts with line by line itemized suggested repairs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
