Seems there may be a trend arising with LED Headlamps that have been replaced.
On mine, the gasket for the turn signal LED module was torn and water entered into the headlamp and pooled at the bottom. Once enough built up, it leaked into the Headlamp Driver Module and shorted everything out.
A tiny amount of condensation is normal with extreme temperature or humidity changes, but should clear within 10 minutes on an LED headlamp. There are two recirculating fans that operate to cool the heat sinks even with the ignition off. If you have condensation for more than a couple of hours or can see streak marks on the inside of the lens, push your dealer for replacement.
What would have been a less than $1500 warranty claim submitted by the first dealer I went to, ended up being just shy of $18k from a dealer while I was on a road trip.
