Radiator bottom hose broken

[alpac]

I was was coming back from a 20mns drive this evening when the message 'check coolant level' appeared. I step out of the car and could hear a big pchiiiii! I opened the hood and saw that a hose at the bottom of the radiator was gone. I can see a hole at the bottom of the radiator where I guess the hoose was attached to. I do not know yet if the hoose attachment part of the radiator is broken or if it is just the hoose which is gone. Recently I had another cooling system problem when the top hoose between the expension tank and the radiator broke. Is the cooling system a weakness of the X5?
