I'm not going to take it in again just yet
and especially with this erratic behavior
and I've already spent near $2000 on it.

You need an OBDII scanner and check for Pending codes.
https://www.kbb.com/obd-ii/on-board-diagnostics-guide/
The equipping of the car, varies with model year. At
one time, you could barely get a set of basic codes from
cars. That article mentions that now some cars have Bluetooth,
and you need a program for your SmartPhone to read that out.
I believe you can also get devices that plug into the
diagnostic port below the steering wheel area, and convert
the info to Bluetooth.
Mine is just a cable that plugs into the diagnostic port
(a wired scanner), and the diagnostic port also has +12V on it,
to power the scanner. That is how the display on the scanner lights up,
when you put the key in.
I found a web page for my car, with the basic codes on it,
which includes the nuisance ones like "Emissions: gas cap loose".
Then when you go to the dealership and buy a gas cap, it's
the wrong one :-/ (Even though you bring the VIN and the
part number comes from their computer, and the part number
label is on the bag with the gas cap... it's still the wrong one.)
I would think, that any time the red light comes on, there should
be a code ready to be picked up by the scanner. If the code is
"transient", then a Pending code is delivered. Any condition
which leaves the red light on solid, then that would also
be reported as a solid error in the scanner. Both can be
cleared by using the button on the scanner interface for
clearing the codes.
While you can run the cooling reservoir too low, other
faults include sludge plugging up the cooling system. Some
car models are more known for this than others. Same goes
for lubricant (oil) sludge on engines which "run too cool". One
of my cars even had a recall for the cam shaft, because
the oil distribution system was not lubricating the
last cam on the cam shaft. So the cam shaft got replaced for
free.

One of your automotive parts retailers in the US, allows customers
to borrow a scanner from the desk, and go out and check the
car. If a person is skint for cash, that's an alternative
to buying one. Assuming you can get your car to the
place to use it.
It's too bad the connector is so inconvenient
to work with. I always had to do contortions to be able to
see the connector so I could mate the cable. The people who
designed that connector, certainly did not worry about
"smooth capture" in the connector design. The connector
is "robust" but "minimally functional" in terms of how
smooth the insertion is.
If they'd designed it properly, it could have been just a
USB connector. But just our luck, they use a plastic automotive
connector.
