2011 Lincoln Mkx

First incident 10-15-2019 (purchased used vehicle 09-30-19) Exiting freeway at 55mph and suddenly brakes stopped working( was able to pull aside) then brakes worked normal again. Took vehicle to check breaks and nothing wrong was found. Second incident 02-17-2020 Driving son to school at 35mhp brakes stopped working while doing a right turn and ran over sidewalk to avoid hitting vehicle in front. Bumper got a little damage. Brakes check again and nothing was found. Third incident 05-15-2022 Driving at 55mph on road and brakes stopped working before trying to stop at red light. Hit cement in middle of the road to avoid crashing. Used emergency brake and Bumper was scratched. Turn on and off truck and brakes work normal again. June 22-2022 Took to mechanic after being inspected at several places and found nothing wrong. Replaced brakes, Front shocks and fluid. November 23-2022 Driving on freeway at 70mph. Brakes failed again and almost crash with eighteen wheeler. Was able to hit the brakes with all my strength and merge into honking traffic to pull over on the freeway emergency lane. (could have been fatal) This incidents indicated are major but the problem has been in occurrence on and off randomly and frequently.

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.
