I have my Y in for a service appointment right now for this issue and others. The rep. I met with for the drop off had an interesting response, he said: "this is now the second time I've seen this issue - I'm not sure if this is by design or not so I need to do some research with Tesla to find out".
I haven't heard more from the rep. yet (it's only been a couple days and I had like 15 items to address) so I though it would be helpful to hear from the group here if your Y also has these cuts/slits or not on your seals. You have to pull the seals slightly with your hand to make them visible, picture below of one of these seal slits. Important to note all 4 of my door seals had at least 2 or 3 slits in each.
