That's insane... My car will never see rain so not really an issue for me, but insane nonetheless.

It sounds unlikely for you but I've also heard of leaks from cracks in the sealant at the top corners of the rear window. They can be hard to see.

The majority of auto manufacturers use seam sealer for where panels come together and that may deteriorate over time. As stated above, I would start pulling trim and see if you have any water marks or rust to point you in the direction of any leaks.

Here's some helpful threads below for your review.

This is specific to the A-Pillar and contains the Ford TSB about it addressing water intrusion lower than the roof:

Check this thread regarding the rear window channel seam cracking and paint delaminating issue - similar to the front roof channel seam issue. Some M6G members are having severe cracking at the rear window channels, not many at the front. This one is the most complete with M6G owners experiencing severe cracking at the rear window channels:

I would also check to make sure water isn’t coming in over the cabin filter. The modern cowl is supposed to have a few drainage holes to allow water to drain out instead of accumulating. There is also a cowl drain with a flap that is supposed to auto open to allow water to drain. If those holes are plugged with debris or the drainage flap is not functioning, it’s possible water could spill over through where the cabin filter is located.
