The tint installer didn't put it back in properly. So it's hanging down in one side. I could take it back. But it's really inconvenient to schedule another appointment. I was hoping to just do it myself.
Both are LED, but the coupe's CHMSL is mounted inside the rear window while the sedan's CHMSL is located between the spoiler and trunk lid.

It was the tint guy's fault. There are two clips attached to the window. I did not know they existed and hadn't seen them in any previous photos. I've attached the photos myself for future reference. Basically, the tint guy didn't slide one of the clips back into the cover correctly. It was a 30 second fix once I figured it out
From the top of the cover, the part that is closest to the front of the car, pull straight down. There are two plastic plugs on either side. They will pop out and not break if you do it carefully. Then you can easily slide the cover out from the two clips. It will be loose enough that it shouldn't harm the tint at all.
There are two white ones in the brake light cover. It's possible that if one is missing the clips are still holding it firmly to the window.
There are two black plugs that go in the top liner on either side of the brake light. It would be easy to spot if one of those is missing.
