my car was overheating, but the overheating didn't went into red zone. slightly above the normal range and there was coolant leak on the day happened.

Next day, I checked with mechanic to see if leaks there. They pressure tested and don't find any leaks.

After they returned the car, again everything seems normal(driven for 4 days).
seems thermostat is sticky. I bought a thermostat just in case if problem repeats.

Background:
First time I observed, I was on highway and it's cold (40 F)outside and my a/c is in auto mode. In a/c auto mode, a/c is still throwing cold air. I switched to a/c econ mode, switched on leather seat heat buttons(both driver & passenger). After few mins, I observed overheating problem(though it didn't went into red zone). I turned off leather seat buttons and a/c. then it came to normal.

Second time I observed, the following day after few miles driven with a/c/heaters all off.

After mechanic returned car, no issue observed.

I'm wondering, is the problem just with thermostat or anything else?

Thanks
