Default AC off due to high engine temp

I have a 2012 Cruze. The dumb part of this is that I canít remember what warning I originally received from my car, but it made me check the coolant level. It was extremely low so I topped it off when the car was cold. It was fine for a while. A couple days later, my coolant was low again so I topped it off again and had a mechanic look at it. The mechanic said he put air on everything and couldnít find a leak (he did find a transmission leak but thatís most likely a separate issue). Also the oil in my car is clean so the transmission fluid wasnít going in there.

Fast forward 3 months and now my car is fine with the coolant levels (as far as I know ha) but when I have the air conditioning on, my temperature gauge will go past half (3/4), my air turns off, then I get an error that says ďAC off due to high engine tempĒ. This happens at any speed (has happened at 40 mph, 65 mph, etc). Also it doesnít always do it. I just sent this car to the same mechanic hoping that heíd find something but he drove it in the morning when it was 70 out and then in the evening when it was 90 out and didnít encounter a problem. I drove it the next morning and it was fine, but later that day I drove it and it went past half, did the error message, but this time my air stayed on and my engine corrected itself. Nothing sounds loud in my car, unless it is actually a cooling fan and itís super quiet. Could it be a temperature sensor? And why was my coolant leaking and now itís not? The mechanic has good ratings and I donít want to take it a huge corporate mechanic and get charged a ridiculous amount.

Today on my way home from dinner with friends my 2013 Chevy Cruze gave a warning "A/C off due to high engine temp" and the fan started running at full speed. I arrived home safely and checked my coolant level which was normal with no leaks anywhere to be found. I let the car sit for a while then restarted it only to find that the fan came on immediately and was running at full speed.
