So the little physical key locking mechanism in the trunk lid... Mine has a huge gap around it:
Water gets inside the trunk LID and drips out of the lock mechanism when I open it. The water isn't leaking past the trunk lid into the trunk, it's leaking into the inside of the trunk lid itself. This huge hole is the most likely culprit right now. My dealer parts guy tells me there is no gasket that is supposed to be here.
Can anyone snap a pic of theirs to confirm that the button is supposed to be sticking OUT of the lid? Also, does anyone have a link to a guide for replacing this part so I can see how it mounts internally and what is involved in opening this up to see why it's improperly mounted?
Thanks.
Edit: it looks like the bracket is sold separately as part # 204-758-00-14, but I'm not sure if this is the problem here...

I discovered a piece of seal stuck to my rear window which is falling off:
This part doesn't show up in the catalog anywhere, so my take is this was someone's half-assed attempt to fix the leak without identifying the problem first.
Can someone confirm this piece is extraneous?
Edit: this piece could also have been added as a half-assed fix for ANOTHER leak that I haven't found yet. And it might have actually served this purpose at some point...
that piece of rubber glued to the glass is a factory feature. I have it on MY'14 W212
I'm starting to think that rubber piece isn't available as a separate part, and it only comes with a new rear window... So I'll just find an appropriate adhesive and stick this one back on...

It doesn't look like a necessary seal piece... but you have a leak coming from somewhere so the easiest thing to do is rubber glue it back original
As soon as it gets back above freezing, I'm going to do a proper water intrusion test to confirm where the water is actually entering from. Maybe the gap around the lock mechanism is a red herring.

I look forward to knowing what did leak
self-sealing rubber pins ...
These little guys 8x pieces total go from rain collection area directly into trunk area.
One missing and trunk payload becomes a profit center on either side premium accessories.
That side of the trunk lid as well as the left and right edges are all pinch welded shut, so the water must be coming in along the edge near the license plate--up by the lock mechanism somewhere, but I can now see that the trim that goes around the lock mechanism isn't sealed either. I need to pop it off and see what is behind it which IS supposed to seal...
It appears that water could be entering at one or more of these areas to collect inside the trunk lid, though the Star would be my first look. I wonder if there was ever collision damage to the trunk lid and it was replaced.
Not likely the STAR logo as water leak source for now a 2014 car, as this kind of nylon grommet last very long and this one never get UV exposed.
Still we need to check these when they go older
Very good points. Thanks for all the pics and quality info.
I'm going to go over every single possible leak point in the trunk after I fix this stupid leak in my cooling system at the interface to the windshield washer reservoir.
