NHTSA Complaint #11595909 — 2020 FORD F-150

On or about April 2024, the "check engine" light came on in my 2020 Ford F-150. My vehicle was just becoming due for re-registration. I had the code for the check engine light checked at my parts dealer and double checked at the maintenance facility I was having services done. The check engine code was for the catalytic converter. I had the catalytic converter and O2 sensors replaced at my service provider, the check engine light was extinguished and the codes had been removed, the vehicle emissions no longer reported on the service/inspection station and the vehicle passed the emissions/safety check for re-registration. In less than one month, the check engine light came on again, with the exact same codes that identify the catalytic converter failing. Both the parts dealer and the service provider tell me that it's impossible. Further checking by the service provider with Ford motor Company service center have told my service provider that my vehicle needs to have the onboard computer system erased and re-installed at my cost because only Ford has the program to do it at their service centers exclusively. This problem seems to be appearing with other Ford vehicles of the same year and engine size. I personally stood in line behind another man who was reporting a problem with his vehicle with the check engine light. Jokingly, I made the comment, "It must be a Ford" and he turned around and asked me "How did you know?" His vehicle is a 2020 Ford van that was parked outside next to my truck. It also has a 5.0 liter V8. Currently, I am awaiting an appointment at either Casa Ford or Visa Ford, the earliest opportunity for them to reprogram the onboard computer system.
