2019 Nautilus Overheating

[Carmasterone]

Does anyone owning a 2019 Lincoln Nautilus experience overheating issues, and or loss of coolant ? My Nautilus continually overheats and uses/loses coolant especially at highway speeds. No visual leaks, I have had the thermostat checked and intermittently I have added a gallon or more coolant when the engine light comes on when overheating occurs. When it does happen I pull over, let the engine cool down, add coolant and I am on my way. Never seems to happen during city driving local repair shop is baffled as well. Someone suggested a new radiator cap. Just looking for help, thank you in advance.

Your overheating/loss of coolant problem needs to be diagnosed right away. Engine destruction is at risk.
Find out where that coolant is going asap.

Is it going into the engine oil or is it going out the exhaust pipe?
Is the water pump shaft seal leaking only under pressure?
A shop can diagnose the engine coolant for exhaust gases.

What engine do you have?

The 2.0L (4 cylinder engine) has a known issue for coolant leaking into the cylinders and being burned. There should be a replacement program for these engines with a new block design that fixes this. I would check with your local dealership regarding this matter sooner rather than later. As mentioned before, engine destruction is imminent. From the sounds of your post it is highly likely that it is already occurring.
