Thanks for the info. Is this something that they had to remove the bumper to do or was it something that can be done with minimal disassembly?
Remove the bumper cover with attached grill.
Hobby grade double sided tape could fix this. My passenger side has this I just noticedIt is quite noticeable if you know where to look. I looked at a co worker's 2018 Si and he had the same gap. It seems to be worse on the driver side but is also noticeable on the passenger side. Not sure if it came from the factory that way or if it just popped loose over time. Anyone else have this gap?
Mine doesn't has the problem, but it looks exactly like yours when I pull the cover out. All you need to do is just simply click it back. The plastic pieces that don't go in are the retaining tabs.Yeah, same here. Bought my '18 in November. Looked fine until a few weeks ago. I am wondering if the heat from sitting in the sun possibly causes it. The rubber is a small part of the entire piece that runs along the lower windshield. It is almost like the hard plastic around the wipers is warping and pulling the rubber. It really is a crap design at the ends there. Picture below shows it pulled out all the way-that tab is soft rubber and is supposed to catch the fender lip and it is not strong enough to hold....only thing I have been able to come up with is gluing it to the fender....not a fan of that plan though....
