NHTSA Complaint #11482444 — 2011 LINCOLN MKX

I have had fairly issues with overheating and have had several repairs done including: 12/29/2019 - Radiator Fan Assembly and Electric Fan Motor Replacement 10/02/2021 - Replace Thermostat and Gasket & Replace Coolant Recovery Tank 8/9/2022 - Installed Module, Control, Sensors and Fuel Filler (all done with regards to presumably fixing the overheating and RPM fluctuation while overheating) I paid $3K for the August 2022 repairs and they told me they could not replicate the issue but believe that the repairs are related to the problems I am experiencing. I use my car to drive to periodically drive to another town (60 miles away) and then to drive to the airport for work (about 25 miles). After August, I took my car on the 60 mile drive and 30 miles in, the car started overheating. I called the Ford dealership and they told me to check the radiator (it was full and slightly bubbling). The idea of driving a vehicle that is not safe (not going to make it to my destination after repairs intended to do so) is terrible. When I got back home (terrified after having to drive the same car back 60 miles later that evening), I took the car back to the same Ford dealership. After a couple of days, they told me they THINK it is the internal water pump. When I asked them if that would guarantee the fix, they said NO because no codes are showing up and there are no other signs of overheating (so it SHOULD be the internal water pump). This does not seem right to me. The car has electronic sensors everywhere and the dealership put me back on the road with a car that started to overheat within 30 miles.
