I thought my halfshaft seals was leaking also, turned out to be the axle boots themselves. It seems the
oil separated from the grease inside the boot, running down the flange only after the car set for a couple of dats with no activity. As soon as I get some run in time, I will pull them and have them rebooted or possibly replace the whole assembly. My car is still new, I'm sure there will be some more "warranty" issues to take care off.
