Pano sunroof self adjust while driving

Hey guys i know its October and Halloween is around the corner but either my sunroof is haunted or something is glitching out! Over the last few days while having the pano roof tilted open (not retracted) while driving i hear the distinct noise of the sunroof motor trying to close the glass. Its done it a few times but never caught the roof actually closing until this evening. As i was merging onto the highway i heard the noise and quickly looked to actually see the sunroof go from fully tilted to about half tilted...no inputs or switch touching on my end. Anyone else ever experience this?

It open and closes depending on speed, to reduce noise/wind/drag

Is that a documented feature? It seems to be random and haven't been abe to duplicate on purpose...just totally random.

It is documented in the manual, where there are two common occasions where the pano roof can automatically lower/raise depending on the scenario. There is one more occasion where the roof can auto-close, due to PRE-SAFE safety feature before a possible collision.

Rain closing function when driving - Vehicles with a panoramic sliding sunroof:
If it starts to rain, the raised sliding sunroof is automatically lowered while the vehicle is in motion.

Automatic lowering function - Vehicles with a panoramic sliding sunroof:
If the sliding sunroof is raised at the rear, it is automatically lowered slightly at higher speeds. At low speeds, it is raised again automatically.

My sunroof leaked a little water when i went through the car wash twice. I could feel it on my face. When I took it back to the dealer, they said "its normal, within spec"
Lmao ok...
