Have you got Coolant in the Radiator? Low collant levels will cause cold hair to blow through the vents becuase there isn't enough warm coolant getting into your heater core. So it will just drag cold air in from outside. Check the Radiator before you start your car next. (DO NOT CHECK IT WHILE THE ENGINE IS WARM! or you'll be making a trip to the hospital ;) ) That, or your thermostat might be stuck... but on a car that new... I would hope not...

Definately sounds like a coolant transfer issue. Either no coolant or the thermostat is not working correctly. I would have the thermostat changed and the system flushed. Also, make sure they purge the system of air as this can cause engine overheats. I've also read on a couple of other message boards that the radiators fail often on these cars. I own a 300m and am going to change mine out due to a leak on the passenger side of the radiator.
