Hole under wireless charger
I was driving today and the active brake assist kicked in when driving through an underpass. Suspecting that it was because of the sudden shift from bright to shadow. There was an orange soda in the cup holder and half of the content spilt. I tried to clean as much as possible but noticed that there was a hole under the wireless charging pad rubber.
Anyone knows if that's a drain? I'm afraid that the sugar water will cause damage to some wires.

Hopefully the rubber stopped the majority of your orange soda from getting through.

I think it is a good guess that it is for smart phone cooling due to the fact that the rubber pad over it is perforated and has small bumps to raise it and allow air movement. If so, this is a good, unadvertised feature.

Very interesting. My GLC wireless charger is the only in-car charger that I've used that doesn't heat up my phone. Maybe it's an A/C vent for phone cooling? Kind of like some cars have that little vent in consoles and glove boxes.

The chances of fluids entering this area are slim, but it's still a silly design choice. If fluids do enter this hole, and if there are electric components underneath, they are likely to get damaged. It looks like they designed it better with the new Electric GLC where the wireless chargers are in a separate area slightly higher than the drink holders.

This would make the most sense. I tried holding my Grainger above the hole while driving more csr today and didnt feel any air coming out of it. Unless it's only active when the phone is placed on top of the rubber pad. I don't see any fans either.
