Project #47945: Auto Repair

I have a 2017 buick encore preferred turbo. I can only drive the car for 10mins or less before the small hose on top of my coolant reservoir pops off and in return my car overheats. Im not sure if I need a new reservoir or thermostat. Or if one of the hoses is clogged. The engine has always ran very hot but never overheated until monday. And my coolant reservoir empties every couple of days but i haven't found any leaks. I know i need my vehicle for work and I've missed 3 days already. Thank you
