NHTSA Complaint #11616359 — 2021 LINCOLN AVIATOR

I have been reporting an issue for over two years with multiple dealerships regarding a sulphur and other strong exhaust smell. This Sulphur smell is most problematic and occurs most often at least one per day. This issue started off intermittently but is now occurring as increase frequencies. The Lincoln dealerships tell me this is normal.  I am not sure what system is exactly failing as no codes are being presented (so says the dealership. This smell is so strong and can be easily smelled in the car but even more once opening the doors or hatchback. I have children that breath this air as well as myself. Often children (my own as well as school friends for which we give rides to) complain about this smell and it is very noxious in nature. This issue has been reported to the dealership MULTIPLE times (Actually reported to two dealerships). Often, I am being told this is "normal" due to gas used. In beginning they would not even log my concern, but this past year I have been submitting online. Always no code so no issue. No other troubleshooting is done. I have even requested additional basic troubleshooting data and not received. This is not a normal smell, as the Lincoln dealership(s) suggest. This smell makes us feel unpleasant. This smell is strong and is hazardous to the health of my family and others. I need Ford to take this issue seriously. Symptoms experienced indicate there is likely a problem with the catalytic converter and they are not addressing.
