Antifreeze Loss/NO Leaks?

The only thing I can think of is a blown head gasket could leak coolant into the block on most cars... check your oil for signs for water or overfilling immediately.

The oil level is fine and also it seems that hot air is coming from the vents inside the car with the AC system turned OFF, that hasn't happened before either.

My vents blow warm air with a/c off too. I've heard of others having this problem so it may be normal unfortunately.

Hey,
My 2011 Touring Z has the same issue, loss of fluid, smell, no leaks, no antifreeze detected in the oil. Any advice would be great, thanks

How much are you losing?

Yes you do have a leak. Put your Z up on jack stands and take off the belly pan. Get a flashlight and look around for dried up green or blue coolant. Use a cooling system pressure tester if you got one. This will help force coolant out of any leak points so you can see coolant dripping. I know a common leak point on our cars is the plastic restrictor between the two right side heater hoses. Mine started to crack. Or, check the weep hole for the water pump. You'll see witness marks on the left hand side of the block.
