NHTSA Complaint #11584651 — 2015 KIA SOUL

My catalytic converter failed just under 4 years after getting the SC176 recall done in July 2020. I believe it's possible there was a step missed in the replacement of my catalytic converter related to the recall, specifically the Catalytic Overheating Protection Engine Control Unit logic that may have caused the converter to fail. I do not detect that on the attached receipt from the repair that was done for the recall. Although there were no safety issues that happened, after reading the recall and what can happen as a result of the catalytic converter failing, I am concerned for my safety if I drive it any longer in that condition. The problem has been diagnosed by my local Kia dealership on Friday 4/19/24 and that is where the car is presently. I have attached the inspection report and the cost to fix it. The vehicle has not been inspected by anyone other the Kia dealership. There was a ticking sound when I accelerated that wasn't there before on 4/3. The service engine light came on Thursday 4/4 when I was getting my routine oil changed. I changed the PCV valve and the light went off until approximately 4/17 and then I called the dealership to schedule bringing it in for the diagnosis which was 4/19. This is the only information I have at this time. Any help you can provide will be greatly appreciated.
