Air in coolant system problems. Normally the OEM will have a specific bleeding procedure to follow eliminating the air. We got the car up to temp on a drive then with engine still running took the cap off the coolant resevoir tank and left the car runningthe water should bubble and show signs of air coming out. But somehow air finds its way to get into this and forms air pockets.
If the cap develops a fault or is replaced with one thats not compatible with the system air can get into the system and cause problems. Most cooling systems use sealed hose systems that allow coolant flow within them. Trapped air can prevent the coolant from flowing.
