I recently got my 8th gen about 2 months ago and I have been trying to figure out this problem with the windshield since then. I don’t know what part I need. I came across some other threads about this same issue and they ordered a part that looked like it went from the windshield to the back of the car. I am not missing the piece the runs along the time only that runs alongside the clips. I might be mistaken and that might have been the right part that I needed. If anyone could help I would appreciate it.
